cwlewis123 - When using the Push method (or forehand technique), it actually produces lower penetration because the arc force is directed away from the weld puddle. The Pull method (or backhand technique) will typically produce deeper penetration. When MIG welding mild steel you can use either method, but pushing usually offers a better view and enables you to better direct wire into the joint.

Nice video; very helpful. One suggestion for improvement: note the voltage and WFS values used in each case and, most importantly, how they deviate from the “auto set” values.
Good video Chris, I like your technique. Best thing about welding is every welder has their own unique way to generally get the same result, a quality weld is what we are looking for. You should make another video showing how to finish welding a roll cage in its final position.
I understand your method of turning up the heat to get into the joint better and that is fine. My mothod is to keep the settings untouched and pull back the nozzle exposing the inner tip more allowing me to get further into the joint like your 45 degree example. just be careful not to touch or dip the tip.. Other than the risk of dipping the tip there are no negatives to the method I have mentioned.. Just a tip from a professional fabricator to anyone who may not be so experienced..
Your right about welding thinner tubing, at my job I'm weld pretty much 12 gauge above or below that, of course it's on a lot of farm or rodeo equipment but learning the proper procedures of how hot you should run it to get penetration, this first welding job taught me a lot and hoping to move up to another welding job to make good money, and maybe open up a shop like this to build roll cages or various projects
Miller Welder, thank you for your input, I agree with you on the push/pull statements you made HOWEVER, that DOES NOT apply to VERTICAL DOWN WELDING like shown in the PIPE/TUBE welding shown in the video I commented on; but flat, of course it's true.
He's still going downhill. If he wanted better quality welds, he'd go uphill with a perpendicular or slight push angle depending on where you are on the pipe.
For me this is new also ive been a welder all my life from what i gather pushing a weld is better than pulling because you let less chance of contamination into the weld its self it all depends on argon pressure and if your using flux core wire and the cleaness of the weld material also i heard and i use this on my own mig that using wire cleaner pad and lube pad from cyber weld does keep the wire going to the gun clean and properly lubed for better welds they are not expensive and you can buy a 6 pack three red and three black i use them on my miller 140 mig...and how good the argon/c02 mix is and you have to adjust the pressure up or down 15-25 to see what works
In response to some of the comments, I have welded both in the field on oil sell sites and on roll cages and had them cut apart. It is ok to weld downhill on a cage because you will get the needed penetration and after the main bars are installed, you have to be a contortionist to install the rest of it, only giving the option of welding downhill many times.
Every thing looked great but what I wanted to see more was direction, how welder moves his arms and wrists from the top to bottom around the tube which is the hard part for me to do, making it look smooth.
pretty welds are for guys who have perms. when is this faking chunk of iron gonna end. I like the middle welds the best in the examples of what was cut out. Its beautiful. I cried.
Damn, look at those arcs... this guy's a champ. He never even touched-on the hardest part about welding tubing; making smooth arcs. Pulling a weld around a tight circumference like that is annoyingly difficult. You're basically welding blind. That's why most MIG'd cages have more of a diamond shape to the welds, rather than a circle. Even on 3" exhaust tubing, it's difficult to go all the way around without welding off into the sunset somewhere.
Great video! Noticed that you have a really nice lack of splatter going on and I was wondering how you control that? I can do some good welding with good penetration but it looks like a ball-bearing factory afterwards. I also normally use 75/25 Argon-Co2 and what flow rate do you use and why would you increase or decrease it? Thanks!
+Charles Rutherford Thanks for reaching out. We're glad to hear you liked the video! There are two main keys to reducing spatter: 1. Proper voltage and wire feed settings - too much voltage will product larger "globular" spatter balls, while too much WFS will cause the wire to buck which will also result in spatter. 2. Contact tip to work distance and torch angle - it is very important to maintain a constant contact tip to work distance (for this application, typically 3/8") and maintaining a constant torch angle. This is very critical and difficult to do as you manipulate the welding gun around the tubing. With a little practice, it will become second nature. You are also using the same gas as the one used in the video. Flow rates are usually set at 25-30 cfh. We hope this helps. Please let us know if you have any further questions.
@MillerWelds - The presenter covered the need for change in settings for the tighter corners, but did not say what the changes were. Also noting the base metal thickness, amps, feed rate etc would be good to add.
Hi Patrick, thanks for reaching out. Please reference the video at 4:15-4:40 for what the changes are. We typically don't speak to these settings because everyone welds at a different travel speed, has a different torch angle, uses different techniques, etc. Please let us know if you have any further questions.
I keep seeing a lot of talk about vertical down and vertical up welding, push or pull. Some people question if its good or bad? In the end the answer is.....yes. Anyone can set parameters for a vertical up weld and set them wrong. Yes, one position gives more penetration given the direction of travel blah blah blah. Its a well know fact to all of us that weld for a living. Now, I'm a Welding Engineering Technology major right now and one of the biggest things that our studies have found is that a big part of penetration lies in the work/travel angle. We have found a lot of tests that support the vitality of your need for penetration lies in your parameters (easy enough to figure out) and your work/travel angle. I'm still not sure why this is. I believe that GMAW is becoming such a fast solidification process that lack of penetration/fusion or even partial fusion can be solved by some angle adjustments. Just some food for thought. Not saying I'm right or wrong. Just wanted to let some people know so maybe they could try it and see if it helps somewhere down the line. Cheers!

I was hoping you could answer this, is this technique of goin forward and then back before goin forward again somethin you have found to work good for cages or is this just how you typically weld. Ive seen and done alot of techniques and do this w tig sometimes but never tried it w mig. Your welds look great and was very curious to see the forward then back. Was hopin u could give some insight on that technique. Thanks and love the video ill be tryin it
Brian B The torch manipulation used here was mainly for aesthetics. Torch manipulation works very well when filling any type of gap. As the torch moves forward out of the puddle, it causes a freeze line in the back. As the torch is manipulated back into the puddle, there is increased penetration into the base material. Overall, the strongest weld bead is a steady stringer bead, but most people like the aesthetic freeze lines that torch manipulation leaves behind. Also, the technique used in this video was a circular technique. Please let us know if you have any further questions.
Question: You said pulling is a good method on pipe. I build industrial ladders using 2" mild steel w/ Mig can I also drag around the tubing will I get better pen ?
Pushing usually produces lower penetration and a wider, flatter bead because the arc force is directed away from the weld puddle. In addition, pushing usually offers a better view and enables you to better direct wire into the joint. Dragging typically produces deeper penetration and a narrower bead with more buildup.
Great video! Do you think will be posible to create a strong welding surface with FluxCore (without gas)?. Could you record any other vídeo about it?, video with tips about prepare material, direction welding, protection surface... Thanks a lot
+Carlos QuinT Thanks for reaching out! We're happy to hear that you liked the video. We have a playlist dedicated to FCAW that you might find helpful. You can access it here: ruclips.net/p/PLEF04BE932F8B5E22 Please let us know if you have any further questions. Thank you.
Your video is awesome CHRIS .Is it good to use a MIG light when your welding inside corners? Also Chris, is a 135 MIG welder good enough to start with.? Will the joint welds have the same strength as a 175 welder?
+James Weissbach Thank you for your questions. First, we recommend that you take caution with roll cages because someone’s life may be in the balance of your welds someday. We recommend a 240v power source for welding roll cages. It will ensure you have plenty of power to make a sound weld. We hope this helps. Let us know if you have any further questions.
What voltage were using for this when not in the 45 degree Vee and what voltage when you were? That steel you used? Is it SCCA approved and how much do you think that Camaro’s cage weighed.
Thanks for reaching out. With the Millermatic 212, there is no volt meter or wire speed meter to show the exact setting. The voltage adjustment and wire speed adjustments have reference numbers on the dial for setting the machine. We were at 4.5 on the voltage setting and 55 on the wire speed.
+victormorelo666 Thank you for your question. The amperage is determined by the Voltage setting and Wire speed. With the Millermatic 212, there is no volt meter or wire speed meter to tell us the exact setting. The voltage adjustment and wire speed adjustments have reference numbers on the dial for setting the machine. We were at 4.5 on the voltage setting and 55 on the wire speed. For more information, you can also reference our MIG Calculator on our website: www.millerwelds.com/resources/weld-setting-calculators/mig-solid-core-welding-calculator Please let us know if you have any further questions. Thank you.
We are using a couple different “stitching” techniques. Sometimes we do “small circles” and sometimes, a slight “back and forth” motion. These welds could also be done without a “stitching” technique by running in a straight line.
valveman12, Starting and stopping on roll cage tubing is very common. Normally with thicker tubing, starting and stopping is always a point of possible failure due to the colder starting point. With stock car chassis, most of the tubing thickness is .120 wall, making cold starting less of an issue. Also, the massive amount of tubing and triangulation in chassis design overcompensates for any individual stressed applied to one select weld starting point. If you are concerned about starts and want to make sure you are at a higher weld temperature when you hit the weld joint, start (partially) on the stop point of the previous weld, then roll into the joint. Another way to help ensure that your starts are quicker is by clipping off the ball that forms on the weld wire after you finish the previous weld, prior to starting the next. Keep in mind that if you change your weld position and travel from a pull to a push, or vice-versa, the weld will look noticeably different. It takes a slight machine adjustment to go from pull to push and keep the weld appearance and penetration similar. Please let us know if you have any further questions.
+TransAmDrifter PL It will depend on the roll cage material and sanctioning body rules. While mild steel cages can be MIG or TIG welded, we recommend TIG for 4130 Cr-Mo cage material. Please let us know if you have any further questions.
2:35 + 3:00 + 5:00 = Nice Welds. The others (not counting the beginning counter-examples) not acceptable. BTW: VD is OK on thin metal and usually necessary to prevent burnthrough.
Quick question regarding amps and wire speed I’ve google amps and wire speed charts and in one miller chart it says when using .30 mig wire size the speed is 2 ipm per amp and i just downloaded the Miller app and in there it says 2 ipm per amp when using .35 wire size im a bit confused now with your experience which wire will it be easier to control the wire speed? In which wire size do you usually go 2 ipm per amp or roughly close to 2ipm?
Hi Corona, thanks for the question. What machine are you referring to in particular? The majority of our small MIG welding units don’t show the welding amperage. Our machines show a 10-100 scale, which is going to be a percentage of the wire speed that a particular machine is capable of running. Thank you.
Miller Welders I didn’t make my self clear i apologize for that! I meant to say that in most welding charts i found in google they say that roughly 2 ipm per amo when using .030 mig wire and in the miller app it says 2 ipm when using .035 mig wire, my questions is in which mig wire are size are you more likely to go 2 ipm.
derpy swagerz We recommend using the Spectrum 625 X-Treme, a portable and powerful 40-amp plasma cutter that offers 5/8 in. mild steel cutting. See the following product page for more details: www.millerwelds.com/products/plasma/product.php?model=M00243 If you have any further questions please let us know.
+toolman talal Thanks for your question. We would recommend using a MIG process to weld in this application. However, if that's not possible, you'll want to use a 3/32" size 7018 electrode. This is a good electrode for welding in all positions, so will work well to handle tubing. To weld with this size electrode, you will need between 65 and 100 amps, depending on how thick the tubing is. For heavier frame rails or tubing (1/8" or higher), you can increase the electrode size to 1/8" and use a 110- to 160-amp machine. Good luck - let us know how it goes!
The funny thing is that they don't want you to stop your welds either. They want a continuous weld. Kind of impossible to do vertical up all the way around without stopping. fyi I'm being half way sarcastic.
vertical downhill is usually the sign that its a cheap job , farmers weld like this in sheds , try that on a pipe line job and you will be on your way home by lunch time.
tom thompson I agree but this is just short circuit mig and Brandon the machines they use are different when it comes to pipe it's either stick or dual shield and you drag not push
Hi John, you can call our tech support team at 920-734-9821, or you can send a message by filling out the Contact Us form on our website: www.millerwelds.com/support/contact-us-form.
Potog13 - Yes - A 180 amps welder would be enough to make weld on roll cages. We recommend downloading our Miller “weldsettings” app ( www.millerwelds.com/mobile/ ). This app will give you the recommended settings for the different types and sizes of wires. Please let us know if you have any further questions.
What amps/wire speed and volts was he at? I use the exact same mig welder at my school, that way i could get a rough idea when I practice on bars/pipe.
monsterink101 It's going to depend on how fast your move or manipulate the MIG gun. A good starting spot would be voltage at 4 and wire speed at 50 for 1/8 material, or voltage at 3 and a wire speed of 45 for your .083-.095 thickness. Hope this helps.
if I could weld that nicely I wouldn't even paint the finished product lol... just prep-wipe nice and clean and clearcoat, let the artistry speak for itself...
Yes, truth. I would have done a bit more practice before committing it to Video for all to see. At my School Mig Pipe is 'B' so there is no way that would have been accepted, 15% better would barely pass unless you were lucky and the Instructor was busy. I am not saying it is unacceptable.
Thanks for your question, Adam! Straight argon is an inert gas and provides good shielding from contamination, but hard wire steel needs some CO2 added to help with penetration. This is why a 75% Ar 25% CO2 mix is preferred for solid wire steel wire in the short circuit transfer mode. If you use only 100% argon, you will have a high, ropey, crowned weld bead with shallow root penetration. 100% argon is commonly used for aluminum wire. Let us know if you have any further questions. Thank you!
I liked how he used it in the manual mode...because the auto mode sucks! Mine was an out of box failure and had to be sent back for a board replacement. Even after the board replacement the weld stutters at the beginning of each weld, almost impossible to accomplish a decent plug weld on auto body panel thickness'.
Gary - you may want to check a few things to make sure the Auto-Set function is working properly. You're connected to 208V or 230V power, correct? A good ground is key, so make sure all paint is removed. The Millermatic 212 is a bit more sensitive to stickout lengths, so make sure to shorten up that distance as much as possible. If you've tried these fixes already, you may want to give our service guys a call when you're in front of the machine to talk through some other possibilities. You can call 920-734-9821 and ask for MIG service. Let us know if you have any other questions.

stop putting going back with your torch in the puddle, each time you do that you stop the penetration in the front of your weld. AND ALSO DON'T WELD DOWN HILL IT HAS NO PENETRATION!!!!
Interesting that you say a downward weld has no penetration.. I am a professional fabricator and I build things that are shot at regularly such as reactive targets like Pie racks, dueling trees, IPSC Targets and lots of other odd jobs that require Armor plate and etc.. A lot of times I use a vertical down technique on crucial areas and even though people are shooting thousands and thousands of rounds at the things I build, I have yet for anything to come back that has broken or failed. Proper technique, heat and travel speed are what gets good penetration. Not the direction you travel. As far as push/pull blah blah, I have to do it all and it is more a matter of circumstance and preference than it is strength. We have tested it and I am here to tell you that a vertical down weld can be very strong.. If it can stand up to the vibration and force transferred from the impact of a .50 cal rifle round or .338 Lapua I think it is fine for a roll cage ;).. I am the lead fabricator of Armorgeddonready.com the targets I build are used at competitions as well as training facilities and gun ranges. if they failed, they would not be.. That is all..
drvn1 i believe that down hill can have penetration.On smaller material thicknesses. Bet when you get into heavy plate and structural welds. Or any thing that is under constant pressure or load. You should always run uphill... Down hand has its place. As in fast production and products that are not great loads of pressure. Also is depends on type of filler you are using. That is just my two cents.. .
I guess a .308 round at 10 Meters doesn't create any pressure, or the .50 Barrett at 100 Meters.. All the things I build can be found here.. We do pretty much anything you can think of when it comes to armor.. www.armorgeddonready.com Everything you see on this site I built.. Now granted most things are not welded in a vertical down motion but some things are such as the hinges on the Pie rack and the Brackets that hold the paddles on the dueling tree.. .. Thousands of rifle rounds and no weld failures.. Material ranges from 3/8 to 1/2" thickness.. 1/2" is the very hard AR550 used for the High powered rifles.. such as the .50 caliber sniper rifles and etc.. There is also the "Pulse mode" on the Miller 350 that we use that works very well for the thicker materials. Good setting for Pulse with .035 wire is 25, 440.. When welding in the normal MIG setting with 3/8" down to 1/8" material I have found that 18.1, 282 works really well.. Now I will admit that a Verticle down weld is not as strong as a horizontal weld whether it be a push or pull. However I have one question for you.. Would you rather have a not so good welder which in my experience 80% of welders fall in this category do an upward motion or have a really skilled welder do a vertical down? The main factor in my mind would be the welder and not so much the direction :)

What about directing the shielding gas? You lose some of that without the nozzle don’t you? Wouldn’t that hurt penetration some? Seriously asking.
As a Welderman,I Like the shows,thanks.
It's me,
Sule
Greetings, Welderman!
I didn't realize vertical down was acceptable for a certified cage. I did all mine vertical up like a Boss!
Your right about welding thinner tubing, at my job I'm weld pretty much 12 gauge above or below that, of course it's on a lot of farm or rodeo equipment but learning the proper procedures of how hot you should run it to get penetration, this first welding job taught me a lot and hoping to move up to another welding job to make good money, and maybe open up a shop like this to build roll cages or various projects
Why is the completed cage missing weld?
Brian Dunn I was looking for this comment, almost gave up and said it myself.
If you look through the bars you will see the concrete floor. Its not complete.
great tips, just learning to weld roll cages atm and this is really helpful!
Great welds . Does he come with the Miller ?
I'm not a welder, and those first two samples made me cry.
I'm always looking for ways to make the welds I make with my powermts better. Thank you for your informative videos.
Excellent welding Chris and done properly
Excellent video. I want to start using some of these techniques with my everlast welder now. Great tips.

Very good welding.
Are you using lower case E or forward backward motion? Does it make a difference either way?
Damn, look at those arcs... this guy's a champ. He never even touched-on the hardest part about welding tubing; making smooth arcs.

Is a millermatic 180 auto set welder good enough to penetrate and weld this dom material?

Brian B The torch manipulation used here was mainly for aesthetics. Torch manipulation works very well when filling any type of gap. As the torch moves forward out of the puddle, it causes a freeze line in the back. As the torch is manipulated back into the puddle, there is increased penetration into the base material. Overall, the strongest weld bead is a steady stringer bead, but most people like the aesthetic freeze lines that torch manipulation leaves behind. Also, the technique used in this video was a circular technique. Please let us know if you have any further questions.
Question: You said pulling is a good method on pipe. I build industrial ladders using 2" mild steel w/ Mig can I also drag around the tubing will I get better pen ?
Pushing usually produces lower penetration and a wider, flatter bead because the arc force is directed away from the weld puddle. In addition, pushing usually offers a better view and enables you to better direct wire into the joint. Dragging typically produces deeper penetration and a narrower bead with more buildup.
Great video! Do you think will be posible to create a strong welding surface with FluxCore (without gas)?.
Could you record any other vídeo about it?, video with tips about prepare material, direction welding, protection surface...
Thanks a lot
+Carlos QuinT Thanks for reaching out! We're happy to hear that you liked the video. We have a playlist dedicated to FCAW that you might find helpful. You can access it here: ruclips.net/p/PLEF04BE932F8B5E22 Please let us know if you have any further questions. Thank you.
How do I sighn up for this certification
Your video is awesome CHRIS .Is it good to use a MIG light when your welding inside corners? Also Chris, is a 135 MIG welder good enough to start with.? Will the joint welds have the same strength as a 175 welder?
+James Weissbach Thank you for your questions. First, we recommend that you take caution with roll cages because someone’s life may be in the balance of your welds someday.
We recommend a 240v power source for welding roll cages. It will ensure you have plenty of power to make a sound weld.
We hope this helps. Let us know if you have any further questions.
It's like artwork. Nice.
What voltage were using for this when not in the 45 degree Vee and what voltage when you were? That steel you used? Is it SCCA approved and how much do you think that Camaro’s cage weighed.
Thanks for reaching out. With the Millermatic 212, there is no volt meter or wire speed meter to show the exact setting. The voltage adjustment and wire speed adjustments have reference numbers on the dial for setting the machine. We were at 4.5 on the voltage setting and 55 on the wire speed.
you really inspires !! not sure if you mentioned the amp that you selected to weld those pipes? thank you !!
+victormorelo666 Thank you for your question. The amperage is determined by the Voltage setting and Wire speed. With the Millermatic 212, there is no volt meter or wire speed meter to tell us the exact setting. The voltage adjustment and wire speed adjustments have reference numbers on the dial for setting the machine. We were at 4.5 on the voltage setting and 55 on the wire speed.

Please let us know if you have any further questions. Thank you.
Where you stitching while you were doing the pull method ?
We are using a couple different “stitching” techniques. Sometimes we do “small circles” and sometimes, a slight “back and forth” motion. These welds could also be done without a “stitching” technique by running in a straight line.
For some tubing joints I find I have to stop and start again because of a poor position. Any tips on proper restart?
valveman12,
Starting and stopping on roll cage tubing is very common. Normally with thicker tubing, starting and stopping is always a point of possible failure due to the colder starting point. With stock car chassis, most of the tubing thickness is .120 wall, making cold starting less of an issue. Also, the massive amount of tubing and triangulation in chassis design overcompensates for any individual stressed applied to one select weld starting point.
If you are concerned about starts and want to make sure you are at a higher weld temperature when you hit the weld joint, start (partially) on the stop point of the previous weld, then roll into the joint. Another way to help ensure that your starts are quicker is by clipping off the ball that forms on the weld wire after you finish the previous weld, prior to starting the next.
Keep in mind that if you change your weld position and travel from a pull to a push, or vice-versa, the weld will look noticeably different. It takes a slight machine adjustment to go from pull to push and keep the weld appearance and penetration similar.
Please let us know if you have any further questions.
Miller Welders Than you for the reply and info.
Nice beads and haha your company name has the same second name as me
Thanks man
Isn't TIG method better for quality welds, such as rollcage welding?
+TransAmDrifter PL It will depend on the roll cage material and sanctioning body rules. While mild steel cages can be MIG or TIG welded, we recommend TIG for 4130 Cr-Mo cage material. Please let us know if you have any further questions.
how much would you charge to make a roll cage for a 2000 chevy silverado 1500 L.S.
extended cab
2:35 + 3:00 + 5:00 = Nice Welds. The others (not counting the beginning counter-examples) not acceptable.
BTW: VD is OK on thin metal and usually necessary to prevent burnthrough.
I sure want to build roll cages with my everlast welder.
Quick question regarding amps and wire speed I’ve google amps and wire speed charts and in one miller chart it says when using .30 mig wire size the speed is 2 ipm per amp and i just downloaded the Miller app and in there it says 2 ipm per amp when using .35 wire size im a bit confused now with your experience which wire will it be easier to control the wire speed? In which wire size do you usually go 2 ipm per amp or roughly close to 2ipm?
Hi Corona, thanks for the question. What machine are you referring to in particular? The majority of our small MIG welding units don’t show the welding amperage. Our machines show a 10-100 scale, which is going to be a percentage of the wire speed that a particular machine is capable of running. Thank you.
Miller Welders
I didn’t make my self clear i apologize for that! I meant to say that in most welding charts i found in google they say that roughly 2 ipm per amo when using .030 mig wire and in the miller app it says 2 ipm when using .035 mig wire, my questions is in which mig wire are size are you more likely to go 2 ipm.
There is a missing section in the estructure not welded.
would it be bad if I used a harbor fright welder on my roll cage?.
+Demetri Rubi just make sure it has enuff power to do a proper weld a 90 amp won't do 160 or better
what is the best thing to use for cutting all my metals that precise?
derpy swagerz We recommend using the Spectrum 625 X-Treme, a portable and powerful 40-amp plasma cutter that offers 5/8 in. mild steel cutting. See the following product page for more details: www.millerwelds.com/products/plasma/product.php?model=M00243 If you have any further questions please let us know.
If i gonna be welding with stick welding machine what electrodes should I use? and what amperage for the 30 and 45 degrees ?
+toolman talal Thanks for your question. We would recommend using a MIG process to weld in this application. However, if that's not possible, you'll want to use a 3/32" size 7018 electrode. This is a good electrode for welding in all positions, so will work well to handle tubing. To weld with this size electrode, you will need between 65 and 100 amps, depending on how thick the tubing is. For heavier frame rails or tubing (1/8" or higher), you can increase the electrode size to 1/8" and use a 110- to 160-amp machine. Good luck - let us know how it goes!
Miller Welders thanks this was an excellent answer :) .
Downhill short-circuit mig has a place, and welding cages isn't it. IMHO...
The funny thing is that they don't want you to stop your welds either. They want a continuous weld. Kind of impossible to do vertical up all the way around without stopping.
fyi I'm being half way sarcastic.
vertical downhill is usually the sign that its a cheap job , farmers weld like this in sheds , try that on a pipe line job and you will be on your way home by lunch time.
Pipeline welders typically do weld downhill. Less time = more production.
+Brandon Spence
you think ....
IIRC downhill is ok for up to 1/4" or non structural
tom thompson I agree but this is just short circuit mig and Brandon the machines they use are different when it comes to pipe it's either stick or dual shield and you drag not push
what tools are used to cut the ends off those tubes to have that fish mouth shape?
Thanks for reaching out. The tool used for this is a tubing notcher
Fun stuff
reason for having to turn up the machine when you have the longer CTWD is that the amount of stickout effects the voltage.
Hey miller is there away I can connect with someone if I have any questions so I’m not asking on here all the time thanks

Hello. what Amp do i need to have on my welding mechin to be abel to welld a steel Roll cage?
have a 230V 180amp welder now.... will it do the work?
Potog13 - Yes - A 180 amps welder would be enough to make weld on roll cages. We recommend downloading our Miller “weldsettings” app ( www.millerwelds.com/mobile/ ). This app will give you the recommended settings for the different types and sizes of wires. Please let us know if you have any further questions.
Miller Welders The app is great! thanks :)
No problem. We're glad you find it helpful. Let us know if you have any further questions.
can you use a millermatic 211
What amps/wire speed and volts was he at? I use the exact same mig welder at my school, that way i could get a rough idea when I practice on bars/pipe.
monsterink101 It's going to depend on how fast your move or manipulate the MIG gun. A good starting spot would be voltage at 4 and wire speed at 50 for 1/8 material, or voltage at 3 and a wire speed of 45 for your .083-.095 thickness. Hope this helps.
Ok cool thanks ill give that a shot
Miller Welders
What would the setting be compared to on a miller 211???
if I could weld that nicely I wouldn't even paint the finished product lol... just prep-wipe nice and clean and clearcoat, let the artistry speak for itself...
are you welding side to side or in a circular motion ?
Thanks for your question! Chris explains the welding technique at the 2:43 mark. Let us know if you have any further questions. Thank you!
well at the completed roll cage part 5:35 you missed a weld bottom side 1st vertical from right 1st horizontal from the bottom
Must be the same (missing) weld visible at 0:15 that also caught my eye.
Yes, truth. I would have done a bit more practice before committing it to Video for all to see. At my School Mig Pipe is 'B' so there is no way that would have been accepted, 15% better would barely pass unless you were lucky and the Instructor was busy. I am not saying it is unacceptable.
What setting?
what thickness wire are you using with that mig
Thanks for your question! Chris explains what wire is used at the 1:34 mark.
NICE
you are using hardwire. why are you using 75/25 and not straight argon?
Thanks for your question, Adam! Straight argon is an inert gas and provides good shielding from contamination, but hard wire steel needs some CO2 added to help with penetration. This is why a 75% Ar 25% CO2 mix is preferred for solid wire steel wire in the short circuit transfer mode. If you use only 100% argon, you will have a high, ropey, crowned weld bead with shallow root penetration. 100% argon is commonly used for aluminum wire. Let us know if you have any further questions. Thank you!
would you recomend higher percentiges of Ar over 75/25 ? For example we have 82/18 here too
What size filler wire did you use ? thanks
reaperwayne We used 0.30 filler metal wire on these roll cage angles. Please let us know if you have any further questions.
Thank you
I liked how he used it in the manual mode...because the auto mode sucks! Mine was an out of box failure and had to be sent back for a board replacement. Even after the board replacement the weld stutters at the beginning of each weld, almost impossible to accomplish a decent plug weld on auto body panel thickness'.
Gary - you may want to check a few things to make sure the Auto-Set function is working properly. You're connected to 208V or 230V power, correct? A good ground is key, so make sure all paint is removed. The Millermatic 212 is a bit more sensitive to stickout lengths, so make sure to shorten up that distance as much as possible. If you've tried these fixes already, you may want to give our service guys a call when you're in front of the machine to talk through some other possibilities. You can call 920-734-9821 and ask for MIG service. Let us know if you have any other questions.

stop putting going back with your torch in the puddle, each time you do that you stop the penetration in the front of your weld.
AND ALSO DON'T WELD DOWN HILL IT HAS NO PENETRATION!!!!
Interesting that you say a downward weld has no penetration.. I am a professional fabricator and I build things that are shot at regularly such as reactive targets like Pie racks, dueling trees, IPSC Targets and lots of other odd jobs that require Armor plate and etc.. A lot of times I use a vertical down technique on crucial areas and even though people are shooting thousands and thousands of rounds at the things I build, I have yet for anything to come back that has broken or failed. Proper technique, heat and travel speed are what gets good penetration. Not the direction you travel. As far as push/pull blah blah, I have to do it all and it is more a matter of circumstance and preference than it is strength. We have tested it and I am here to tell you that a vertical down weld can be very strong.. If it can stand up to the vibration and force transferred from the impact of a .50 cal rifle round or .338 Lapua I think it is fine for a roll cage ;).. I am the lead fabricator of Armorgeddonready.com the targets I build are used at competitions as well as training facilities and gun ranges. if they failed, they would not be.. That is all..
drvn1 i believe that down hill can have penetration.On smaller material thicknesses. Bet when you get into heavy plate and structural welds. Or any thing that is under constant pressure or load. You should always run uphill... Down hand has its place. As in fast production and products that are not great loads of pressure. Also is depends on type of filler you are using. That is just my two cents.. .
I guess a .308 round at 10 Meters doesn't create any pressure, or the .50 Barrett at 100 Meters.. All the things I build can be found here.. We do pretty much anything you can think of when it comes to armor.. www.armorgeddonready.com Everything you see on this site I built.. Now granted most things are not welded in a vertical down motion but some things are such as the hinges on the Pie rack and the Brackets that hold the paddles on the dueling tree.. .. Thousands of rifle rounds and no weld failures.. Material ranges from 3/8 to 1/2" thickness.. 1/2" is the very hard AR550 used for the High powered rifles.. such as the .50 caliber sniper rifles and etc.. There is also the "Pulse mode" on the Miller 350 that we use that works very well for the thicker materials. Good setting for Pulse with .035 wire is 25, 440.. When welding in the normal MIG setting with 3/8" down to 1/8" material I have found that 18.1, 282 works really well.. Now I will admit that a Verticle down weld is not as strong as a horizontal weld whether it be a push or pull. However I have one question for you.. Would you rather have a not so good welder which in my experience 80% of welders fall in this category do an upward motion or have a really skilled welder do a vertical down? The main factor in my mind would be the welder and not so much the direction :)
+Kamel Khenifar When you do not know what you are talking about a wise man keeps his mouth shut otherwise he looks stupid and ignorant - like you.
What gas is used to welding ?
75% argon 25% co2 or straight co2
