camera shots are awesome clearer than my wielding mask thanks again
Great way to state that! I've learned more about welding puddle control here than many other sites because of the excellent camera work on this channel.
@@jameswyatt1304 EXCELLENT camera work! Man, that plasma cutter goes through that steel like butter! That was so cool to see.
@@jameswyatt1304 tttt to try
I only use camera shots to view my welds

AWESOME arc shots. Being one that has done some plasma gouging that was really cool to see those arc shots. Nice work guys!
Thank you sir 🍻
-Camera Guy
@@Welddotcom May you please tell us what type of camera did you used for the gouging shots?
Hey Bob- i have the 60i- good machine. I was running at 40 amps and was burning up consumables non stop. I called TD. They said stock consumables and torch are made for 60 amps. The stock number consumables last about twice as long running 50-60 amps. Just figured id let you know great vid
Dang, really?? Never woulda thunk it! Thanks for sharing that, brotha! I have a 60 amp also and my thoughtset on it was that I was saving consumables by running it around 45... but come to think of it, I remember thinking it was odd that I used 1 tip all day w the machine maxed out and gouging/ cutting 3/4" Steel all day... I tried justifying it by thinking it must've had something to do with the moisture content of my air that, which can certainly make a huge difference, but still, I think your explanation might make more sense on that particular day... guess now I know why!
Thanks again!
Cheers mate!

Ps. Weld.com - thanks again for another great video! Keep up the great content!
This channel is the best. The fact we get this awesome training from experienced guys for free? What a time to be alive.
amen brother
Earlier they were up on the roof slapping themselves with hot mops and such.
Had any one noticed Bob has really listened up lately. Loving it, learning heaps bloody good stuff.
Listened up? Glad you're loving the videos 👍
Bob, a very good tip for getting the cut lines to be cleaner. Use a 1/2" thick by 2" wide piece of metal as a guide. Use vice grips to clamp it down to your workpiece and glide the plasma cutter across it. Keeps your cuts much cleaner with less of those waves. Makes clean up a heck of a lot easier.
Great video! Always enjoy watching your videos. I've done quite a bit of gouging with plasma. Its usually easier to get it into tighter spots than carbon arc gouging. Ive found that regular cutting tips work best if you need to be more accurate turn down around 20-35 amps. I use it a lot for removing the welds on hand rails or joints that need to be flush before paint. A lot faster than grinding entirely by itself.
if it sounds like bacon frying you're welding really good. if it smells like bacon frying stop welding and put yourself out
I end up watching welding vids as a pastime. It's tv time for me. Been doing it for years. This is the first video I've seen where I can actually see the rod being consumed as it's fed in. Being able to see the cap of slag form trailing the puddle is nice too, really ties into the perspective on doing it right. These videos are great!
Your photographer could do an episode on how to capture stunning and helpful footage of welding and gouging. The clarity of the puddle, slag, and rod manipulation and consumption is excellent.
Awesome camera work!
I use plasma gouging a lot at work when cutting bucket liners out. You can be very selective of how much metal you remove or let stay. Again great video thanks.
I prefer it for 3 reasons
1. Theres alot less heat sinkage and slag
2. It cleans down to bare metal which equals less grinder time.
3. Plasma cuts are the best cuts next to a shear.
I have the hypertherme 85 almost the Cadillac of plasmas. I work on a lot of spring hangers on tankers. I use the 15 degree angle torch so I can see what all I’m cutting you throw a 2inch or better arc off of one for thight spots. Just keep yourself around 50amps or so and keep a 45 degree angle and stay on top of it.
Mr. Bob is a welding God and welding legend!!
Thank you for your videos!!🤙🤙👍
Great video Bob, all you need now is a bucket to sit on,some Redman and a smokestack turning about 20" per minute
Ever try a gouging rod? Not a carbon arc rod. Years ago I used a product from rockmount research called Electra. These days I get a similar product from my LWS called metal mover. Works really good and is handy when you don't have a plasma cutter in your back pocket. It would work perfect on this demo.
I haven;t tried plasma gouging, it would have been real nice to have used this today, for SS 6g pipe weld.I've used plasma cutters over 10 years almost everyday, they are good machines but need to be used the right way, I think a lot of people haven't used them a lot and think they are the holy grail of metal cutting lol, though good for SS cutting
The veiw from the person doing the gouging is the best veiw, the only veiw that you can really see when you touch the weldmat on the opposite side.
Real people doing real work ,at the end of a shift you can see what was accomplished , that gives you pride and self confidence and pennies in your pocket.
love when the 7018 slag come off like that
I agree, nothing better than a self peeling slag and in the welding context too! Ha ha ha ha ha ha....
Another great video. I have a plasma cutter, but have never tried gouging. I use #5 lens in goggles for OA and plasma.
Plasma gouging ok for straight away seams...but it doesn't gouge corners well at all. We do custom fab for naval projects and have lots of corners, inside and outside. Technology is great for some things, but nothing beat cag when your moving alot of metal for 100% full pen.
Thank you for the knowledge and experience you share. Sorry if my question is stupid. Is it possible to use a plasma cutter without gouging mode for this operation?
Yes. Gouging mode just fine tunes it. But the tips are good to get. Gouging tips have a wider hole for bigger blast
Awesome video and camera work always enjoy
Well done. That was nice and clean join when you were done with that process.
I haven't spent much time at all with plasma gouging either. Always reverted the old tried and tested, dirty and loud carbon arc gouging as well.
I might give that a try myself this week, just to see for myself how well different techniques work.
Love the videos. I wish I had a resource like your channel when I was in trade school and throughout my apprenticeship.
For all you guys just starting out, pay attention to what this guy is teaching. Every resource at your disposal can be invaluable.
Accumulate as much knowledge from him and others as much as possible, then keep what you need and put the rest in your back pocket for another day (figuratively of course) don't be putting rod stubs in your pocket.
Great video 👍
As always well done sir. I love to see that 7018 go in. Learn something every day. I have never gouged with a plasma. Looks so much easier and cleaner than that carbon torch. Thanks for the video
You have to move that plasma very quickly hey. Never seen gouging with a plasma before. Great job mate. You have all the skills 👍
i think a series on backgouging different joint designs would be beneficial especially using different techniques to back gouge be it plasma carbon arc oxy fuel scarfing and grinding
awesome close footage!!!!!!
Pick an angle that works and walk it. Works ever time.
Faster and quieter than CAG. Both processes use air so AWS has no issue, both require grinding to remove oxide and nitrided metal. A real time saver when you have hundreds of feet.
Would have been one pass with 7024 😌
I have done a lot of plasma gouging on cracked truck chassis where no grinder is possible. These things are very cool machines and do an amazing job. The process is, gouge the crack untill nearly through, put on a lower amp consumable and then cut through, clean up and weld. Don't set yourself on fire! Trucks chassis can be very difficult to get out of when the fan goes brown!
Impressive Mr. Moffatt. Thank you for the demo. Interested to see the upcoming comments. Perfect camera shots again.
First off I have to say great camera work. These tip and institutional videos are what keep me coming back. I have never tried this before but I will be seeing a if my plasma cutter has a gouge setting. Great video keep up the good work
Thanks for the support
Plasma gouging it's kind of Handy if you have a big enough plasma and making short runs
Very nice camera work. I've personally used plasma-gouging while working for a BNSF Rail Road contractor. Personally, I prefer to use the Carbon Arc/Air Arc method for weld removal. But for some things, I can definitely see the usefulness of Plasma Gouging. I haven't seen a lot of Carbon Arc processes by your channel. You should do some intricate cutting operations using small diameter carbons. i have used everything from ?3/32"? up to 3/8" carbons for aluminum and steel work. Love your videos.
Far less violent and much quieter than a carbon arch. I never liked the sound of sizzling ear wax. Excellent video, thumbs up and l ain't hitch hiking .👍
Amen man lol
Nowhere near as efficient though
@@robertatwood2503 turn the amperage up and that could be a one pass thing. Looked a hell of alot smoother than carbon arc goughing as well.
It’s much cleaner though, and you have more control.
Went to the bathroom with just the audio playing at the start thinking "man if this wasn't about plasma gouging I'd swear he was burning rod right now" and I am feeling very good and smug at this moment
Thank You for another great video. This video is just in time, next week I start repairing an earth moving scraper. I will spend about a day gouging and grinding. After watching this video I have more confidence that my methods are sound and I will be able to do a good job.
Bob how do know what rod it is without smelling it?! 😂
Derrick Quintal little Earthy Ahh it’s organic
3:00 why cant you amp up the process on the fly? how old is stick welding and we still have no technical help to help us preform the weld better. i should at least beable to adjust the heat range slightly on the fly? yes/no?? or in this case burn the end of the stick a little hotter. with control i can variably or progressively increase/decrease at my demand. seems i've thought should had that feature long before the first microboard. if stick welding is still ultimately the best. why is this continued to get overlooked in this time and age? when anything is made at the slightest whim it will sell more to a few from the masses? I should be a billionaire with all these ideas. it surely isnt going to confuse anyone nearly as much as a mig or tig machine with every possible adjustment. anyway I know. i would buy it.. So `Every:, Body'. certainly would too.
aah yes ultimately I would see the amps displayed inside my helmet
and yes there would be a microboard in the rod holder with thumbwheel or touch sensor control options. controlling the step phases of the inverter process to meter the amps. simple? arc blow??
@@beefsupreme5291 More printed circuit boards = more (expensive, often scarce) parts to break.
Fantastic process and great visually, I am looking forward to more on plasma gouging. What's the cost comparison between abrasive prep and plasma gouging?
Time and materials, is my guess.
I have completed a fillet weld that penetrate that well that it weld to the bench underneath, 1/2 steel plate in 1978, and received a high pass in welding
I must give gouging a try with my everlast plasma cutter.
With plasma gouging (3yrs experience) still learning myself ive found a clean line and a very very steady hand will always favor you my personal experience
I have done quite a bit of plasma gouging on heavy equipment. I usually take a moment and use a piece of scrap to set the amps to get my depth of cut.
Rather than using angle and washing the arc back and forth.
With some practice you can get it so you can remove pretty well exactly what material you need to,give or take 1/32 or so?
So you run your gun more verticle, using amps to get the depth, what does the dross do, does it get blown away sufficiently? Another poster said he's running 80amps, but I don't remember what thickness material.
I still run a slight push angle but I don’t need to go forward and back or adjust my angle to get the depth . I just use the scrap piece and dial up the amps while keeping the torch speed and push angle the same until the depth I’m looking for is achieved.
Then use the same settings on my actual workpiece.
GREAT CAMERA WORK! Made me want to learn !
Maybe something for the shop to look into, work has big shop and all the arc gouging going on when they were doing the sound test in the shop everyone has to wear ear plugs now. If they can bring the sound level do and it’s fast that awesome.
Yes more please.
with the pt31 torch drill out the tip 2.5mm then you can gouge with the cheapo machines
It was cool. I've only done it a couple times then used mig but I'd really like to see it cut open and bent if possible, just to see how the penetration went. Thanks
I've tried it, I found it ok for in the shop and on small jobs, but I can still remove metal faster with carbon arc gouging. CAG is much more portable too I think.
I would say yes maybe. But with the newer plasmas that have the compressor inside them you basically need a gen /power and the plasma. Cag you need a gen and welder and the gouge setup. So I’d say it’s kinda a toss up.
Plasmas more portable not to mention more economical cag needs a massive power source at least 300amps and a lot of air pressure
I have a 600 amp welder generator with a 60 cfm compressor on my truck along, I can run 1/2" carbons and gouge a groove 3/4" wide by 1" deep in a single pass. I'm all set up for gouging with a mobile setup. I showed up a hypertherm Powermax 125 that was a demo for plasma gouging. Plus with that big of a machine, in the field, you'd need a 40kw generator and a 40cfm air supply to power it in the field.
steady as a rock Mr. Bob… thanks for the lesson..
Great shots - great video - thanks
Great video. God has given you great talent and abilities.
You did just fine on your demo Bob. Usually what i do for plasma gauging is i normally run it around 80 amp and upping the air pressure for thick material. Not that there was anything wrong with your settings and understanding it only goes up to 60 amp, just looked like it was a bit more work for it on the 3/8's plate.
I don't plasma gouge very often either , at least the type you did but I plasma cut a lot of old welds on lift gates to weld on new ones. instead of pushing the metal out of the way try a pulling action with the plasma cutter. when pulling you can see the trail left by the weld root \ seam in which the 2 pieces if metal meet a lot better than trying to see through the arc as you push. so if you are cutting you will see the seam appear as soon as your through the weld and if your gouging you will see the seam disappear when you reach the weld with less guess work and passes. this method will leave more slay though , nothing an air hammer or needle scaler won't quickly take care of.
Awesome video. sometimes i also use the plasma cutter to put the angel on the material, instead of grinding it. Bob, why didn't you smell, or lick that rod?. are you feeling ok? lol
Brilliant video thank u
We always try to leave no more than 1/8” to back gouge out. Gouge it, one pass and done.
Can someone explain why this is done? why not fit the piece properly to achieve penetration the first time? Just curious.
I'd heard of CAG, but not seen this. Very good video with wonderful camera shots, solid audio, and humane-to-viewer editing. The quality shows every time you produce a new one and I learn every time.
I have done plasma gouging unintentionally while learning my FP18 wouldn't cut aluminum thicker than a soda can, though it cuts thin steel well. (^_^) With a better PC and skill, it's good to see it as a useful technique.
Got a question? Is it OK to weld out and gouge like that with A.W.S. ? IF IT IS THAT'S COOL.. I've always took my test ding 6.G.R ! Haven't tested in years on flat metal. Just curious.
Love your channel. . Keeps my mind fresh. By going over something different every day
Yep, by AWS D1.1 (Structural Welding Code - Steel) all CJP welds made without backing need to be backgouged and welded from the opposite side, unless you have qualified a welding procedure specifically without backgouging. Most people do not do that, and just run within the boundaries of the prequalified procedures. Also when you say is it OK to "..gouge like that.." the D1.1 has no limits on the process used for gouging except that "oxygen gouging shall not be used on steels that are ordered as quenched and tempered or normalized"
I burnnoff welds with plasma on semi trailer suspension hangers so cleanly ive smack the fram with a hammer squaired up new hanger and welded it rught back on...
Good demo. Never used plasma arc gouging in the field, only in the shop. Carbon arc, used it for decades. But my first go to on heavy equipment and weldments has always been with oxy-acetylene torch with a banana style gouging tip or my modified #2or3 cutting tip with the center blow hole slightly drilled out about 2-3 times the size dia. of the original hole to a depth of about 1/8". Heat it fast to start, get it melting and control O2 blow by feathering cutting lever and move along washing out old weld or what ever needs gouging in ferrous metal. Fast, quit, inexpensive and very accurate. Just can't get deep inside a bore as you can with a carbon or piercing rod. May make a good video to show viewers another option. Thanks Ed K. Cleve. Oh.
With the Thermal dynamics there are A-D tips. A are 10-40 amps (precision gouging like with a Hypertherm 45XP) the B-D re 60-100 amp nozzles with different profiles to the gouge.. I amp thinking you could try some standard 70-80 /100 amp nozzles and expand out the profile with even more options.. I been marking with 120 amp nozzles in the gouge mode, and coming up with excellent results. Even with argon.. It will mark in the expanded metal mode too.. So there is more work to do, and tons of options.
I have been running mine on a CNC table, and there is a auto interface available now. I just wired in my own voltage divider from my hardware setup, but arc good/raw voltage,and contactor is there on the 19 pin inside the machine.. It supports the SL100SV torch, and auto detects when plugged in.. Also the 40 amp SL-40 torch will work with this machine if you really want to get into art/small torch type work.. Nothing in the manaul will tell you this stuff...Just have to know Thermals to figure stuff out..
Pins 3-4 on the 19 pin will fire the torch. In case you want to use the Automation torch on a track burner.. Standard machine torch has trigger wires hanging out the ATC connection so no reason to get into the machine for that one..valve torch is much faster cycling, but really does not matter on a track burner,,
I have the TD cutmaster51 are you saying i could get diffrent but acceptable results putting on nozzles that are not listed as available consumables? I know need is the mother of invention in your case it may have been need and availability. Thanks for your response in advance
Jesus, nice flap-wheel rack. Show-off
We're going to do a build video coming up soon.
Great arc shots. Looks a lot more controllable than carbon arc gouging.
AMEN ON THAT.. when I C.A.G. I look like ELVIS dancing around controlling the arch jump
Hehehehe
I have used this a lot to repair deaper cracks in thicker material rather than spending forever and a day with a grinder or cut off wheel gauging things out. And with some practice you can get things cleaned out to the right depth very quickly!!
You do shop or field work?
Bob, great video and the arc shots are amazing.
im bob moffat hnnnnnnnghhh
Garrett Butler lmfaooo😂😂
best arc shots ever. Nice camera work!
Carbon arc is kind of enjoyable i used to do alot of that at the barge manufacturing facility i worked at (not on my stuff honest to god lol) i didnt mind it all that bad...crazy sparks though
I personally use a slight rocking motion as I go when plasma gouging, especially when removing alot of material, it seems to cut down on how many passes I have to make, and kinda spreads out the slag so it flakes off a bit easier. It works for me, but other people I have talked to tried it and made a mess. Basically keep your "fulcrum" of the motion as the centerline of the deepest point you want to gouge, and rock the back of your torch from side to side SLIGHTLY. It takes a bit of practice, the hardest part for me was following a straight path and doing a slightly unnatural motion, sorta like the way pushing a shortcircuit mig bead feels kinda unnatural at first, especially for guys who do alot of SMAW work.
Just figured I would throw in my two cents, it has worked for me.
Edit: I was told by coworkers that my gouging technique makes it impossible to work near me because it sends slag straight up in the air to either side...so dress accordingly...
perfect beads i love your videos
Oh and on a side note, have you done a series on the different uses of tig electrodes, there characteristics and a deml of each?
Soon.
Highest definition arc shots I have ever seen. I would love to see some super slow motion clips.
The arc from the plasma gouge is incredible - controlled mayhem.
It absolutely is.
what's the air psi on that gouging?
90
I weld ASME pressure vessels for a living. We use Miller MIG's. I've been using a hypertherm powermax 65for back gouging set at 45 amps. A little wiggle followed by 1/8" wheel them a quick 1/4" wheel to clean up the top edges and finish it with a wire wheel. Exray everyday.
You make it sound easy! Thanks.
@@donsmith9081 it really is that easy. I'm the guinea pig at work. I get all the new toys that gets purchased. I wired the plaz to the fuze box and cut some stainless steel. I thought wahoo been doing this for years. Boss said weld 2 plates together 1 side only, then airarc the other side like normal. I saw the setting I needed and blew through. I turned the amps down and tilted the torch to around 1:30 position and pushed my way down the line east peasy. The salesman finally came over and said no explanations needed here and left. Don't forget the wiggle. It opens up the gouge to 1/8 inch .
Don't forget to look in your owners manual. You may have to change the nozzle and drag cup to another type that they will show. For a quick 12 inch section I usually leave on the regular cutting consumables and tilt the back of the torch to the 2:00 position. Remember, it's called a drag cup for a reason. Lay that guy right onto the metal and go for it. The angle is close enough.
If you arc off the metal and cup, change your electrode and nozzle. Same as cutting.
"always change the electrode and nozzle as a set. Store an electrode and different nozzle to keep from burning your torch with mismatched worn parts
Greetings from Australia, you guys do awesome content and camera work thank you.
I do have a question about the gouging.
Are you removing metal deep and wide with every cut or are you just making it slightly deeper with one cut and then widening it with the next cut?
Deep and wide...that's what she said.
@@eduardosampoia5480 lol
Nice video but you didn't show any set ups on the plasma gouging machine..??
Interesting to see that done Bob - useful demo. :)
It is awesome! I've actually used it w a plasma. No gouging but I gouged W it! Lol it's about the angle W that one.
I've done a whole lot of carbon arc cutting, even cutting off bearings on shafts. wondering how is this for cutting bearing races of shafts?
What kind if wheel are you using for clean up?
Wow Bob definitely gotta give that a try thumbs up.
Love watching those rods just melt in.
One of the benefits of plasma arc gouging VS carbon arc gouging, is that you don’t get the high electric demand charges that you pay for the entire month when using CAG. That’s a big deal if you have a small repair job and don’t want to pay the extra fees for a small job.
What chuck Norris uses for a water pick.
When I worked on the River welding barges and boats we would run a pass on the inside and on outside would carbon gouge the weld out to get 100%
OFF SUBJECT: I have watched this channel for about 2 years. What happened to the guy from Ks. that used to run this? I enjoy and learn a lot from you also.
Same guy... We're just in a different shop.
What is back gouging. Please anyone help
how would one prevent the distortion?
I have a 60 amp Miller that I use for gouging. From my experience you are getting close to the limits of usable depth. I must say that it seems more difficult to maintain the arc with the Miller and still keep enough touch angle to move the molten metal out of the groove
Wish I coulda used that inside a bow thruster instead of an arc rig lol
I’ve done tons of carbon arcing, but never any plasma gouging. That was very cool. It also sounds much quieter. The camera shot was most excellent too.
I've only done oxy/fuel gouging in a class room. Was part of my grade to do it correctly.
Anyway's, I thought you were supposed to gouge at a 90° angle. Or is what I'm saying just a different technique?
Cutting, sure. Gouging? Never done it that way.
no 10
Cool video!
Why not just prepare both sides for a full strength weld?
Still would need to back gouge to sound weld metal, but would have to remove less metal by gouging
Dont know why youtubes been randomly unsubscribing me from you and a lot of other channels
No idea. That's the first I've heard of it.
I only gouge to remove old welds so less grinding.
