You make some of the best welding videos Justin. you guys, bob moffat and jodie are my go to for any welding info. you're clarity and straightforward explaination for everything is fantastic, dont lose that quality about your videos!
Thanks for setting that up in the CNC and running this. Good to see some straight up scientific comparison. Think I'll go make one of those gauge blocks that's pretty cool!
Nice videos, used to tig before I lost my index and middle finger on my rod feeder hand and have recently been trying to get back into tig welding again, have to say trying to change which hands are holding the torch and wire have been discouraging to say the least but your videos have inspired me
I was always wondering what the stick out rule was. I am just learning how to TIG weld and this was very informative. I learned how stick out matters and also why you would use a different size cup. Thanks!
Now run 3 more weld lines at the longer stickout (say 12). One with the torch and cup tilted and pointing 'ahead' of the bead (simulating how most folks weld, feeding rod from the front). One with the cup angled backward (which should blow shielding gas back over the bead and keep it shielded for longer). And one straight up / down as you did here.
balisticsquirel was thinking the exact same thing. In theory, due to geometry, an angle should technically all for some degree of extra stickout. I dont think it will be much but should. And then there is still the flow variable and turbulence factor related to it.
Yes and also the blanket behind it will help keep coverage over the weld and flow from cup. Argon is heavier than air. And will fill the area as long as it's covered.
Came here for the post-intro "WTF screen", stayed for a rather informative and interesting video :) Couple of tips about the CNC: You can download so-called 'screens' for Mach3. They are in essence different layouts of the controls. My personal favorite is 'Aqua' since it's not as cluttered as the standard screen and it's design is more pleasant to look at. Number two: for some reason after finishing a pass your CNC wend down to Z0. You should add something like this to the end of the code to prevent this: M05 (turn off spindle or whatever machine thinks is spindle) G04 P500 (pause the program for half of a second) M09 (turn off all coolant outputs, possibly gas to the torch) G0 Z1 (quick retraction to 1" or 1mm above surface) M30 (rewind to start of program) It's good to have a simple text file that you can copy/paste from to get all your basic commands for the beginning and end of the code. Do watch out for G43 (cutter length compensation) since it will send the machine to Z plus whatever-the-tool-table-tells-it-that-the-tool-is-long and it will start working in the air instead of in/on the part. It looks like we are using same software and controller, so if you have any questions then feel free to ask! One more note: another interesting thing is that on that particular controller there are two on/off outputs for spindle, one for CW and one for CCW. They are turned on by M03 and M04 and are both turned off by M05 in the G-code. That means that you can have two attachments on the machine and have it do two things one after another. For example, you can set up the machine to lay a bead with a welder, wait couple minutes for the bead to cool, and pass over it to spray some rust preventative from a can that's activated by a servo.
great feed i'm in Australia & I can't find anyone willing to help with videos so i'd like to say thank you for going out of your way to produce really helpful videos I don't think many people realise how much time & money go into doing what you do
Thank you for all your help I have learned a lot about tig welding.. I bought the prime weld 225 which I saw on one of your videos I like a lot and I am starting to get better at it
Very interesting results with your test on stick out. What would be cool to see is cut and etching to see how the weld profiles are on the different samples. Stress testing results would be interesting to see too. And there is always ways to manipulate the gas where you need it to stay too.
Cool video! May have been worth mentioning that the number on the cup is the cup measurement in 16ths of an inch. So people will know what their cup measures without having to search it or write it down
I absolutely love that gauge that you made. I will try to make myself one tomorrow and see if I can get it on the first try like you did. Thanks for the great information.
Interesting tests. It would be cool to see a similar test with one cup at a typical stick out, but several flow rates. I’d like to know at what point you’re wasting gas with the bigger nicer gas lens setups, and if it’s possible to make them aspirate ambient shop air into the weld like you can with a smaller standard cup.
Great test. Bottom line, my rule of thumb is what ever works best for you to obtain desired results. Being able to see the puddle and add filler accurately is key.
hey mate. ive just got an AC welding machine and watching all your videos. this is an interesting tip I've never thought to do even with my stainless TIG days. I made one tonight from a block of wood and it turns out ive been using to little stick out all this time. cheers.
Just from the first impression of the vid, (and I like to speak out prematurely) is that you sometimes need that tungsten stickout as extreme, (with the proper gas lens), if you gotta get your arc close to the joint, an a tight location that you normally cannot reach. There is a reason, and application for it, now i will finish watching the video of this amazing teacher. Cheers!
I'm still working on my aluminum welding. Not really working on free stuff. Only because, I will still suck at welding Aluminum welding. I enjoy what you do. Continue on. And tech us. PLEASE.
Been welding for years but new to TIG, I have to say Justin, most impressed with your videos. In fact I think they are so good I’ve subscribed for the first time on anything. Keep it up. Cheers from Australia
awsome dude. been welding all my life. never prof. never knew anyone that let me play with there tig. finally got my own. huge help from you bro. really apreciate it.
Really awesome! I purchased an acZdc Tig over a week ago and haven’t fired it up yet. All I’ve been doing is watching all your videos. Thanks heaps for your uploads. The only down side is I’m from Australia and we us the metric system. That block you made transcends all systems of scale. 🇦🇺🤜🏼🤛🏼😎🍀🍀🍀
im just about to purchase a STRATA AC/DC tig and Im looking forward to putting your instruction to the test. I have ARC, MIG and GAS welded before but never TIG. Wish me luck :)
Great vid and info Justin, its something I've always kinda wondered about, but never really got the chance to test out, especially to the degree of accuracy which you have here, which is more than adequate imho. I deffo am with you on going between the 12 and the 8, 8 looks the best to me in this example. It would interesting to see what that same setup would come out like using number 10 stickout. Just FYI, and maybe other folk's too, as a "speed setup" thing, the way I've always set my tungsten is to leave the tungsten loose in the torch while I rest the bottom edge of the cup on a flat surface, the tungsten also of course is down on that same flat surface, it being loose. I then rock the torch either forward or back as needed, eyballing the angles as I do so until the cup and the tungsten create an equilateral triangle like something like this, but "squarer" /\ in relation to the flat surface, (or an "X" type shape - basically you're looking for 90 and 45 degree angles if that makes sense). It's then just a case of nipping down the collet and you're done - with parctice I find it's pretty accurate and can be done in just a few seconds (about 5 or less at a guess, never timed it though)
I'm new to your channel Justin and I must say you have one of the best Welding channels on you tube. I will start digging in to your videos from now on! Thx Justin.
I just have youtube. great vid man. I start my weldin classes in fall. and will be purchasing a tig welder really soon. I'll be sure to remember these tips. thank you👍
Good stuff mate. Any chance you could do the same with the relevant cup sizes and with the cup slightly angled? Love to see the results of this too for comparison. Cheers also for the time and effort you put into your channel. Ive learned a great deal from you and have applied quite few techniques. Keep up the great work 👍🏽
Another great video thanks. It's these details that help understand the how's and why's as i am new to Tig welding. Lots to absorb for a first timer as even basic settings can be difficult when you cannot understanding the problem and need to correct technique or setting adjustments.
Geat video, very usefulI, filled with good information. I don't always get to weld, so whenever I get notified of a TSF video posted I listen and absorb any info you put out there. When I finally gey a chance to weld, I think of what was said in those videos, the new information, and reminders gives me a better plan of action, in m y practices, and helps me consistently become a better welder... Keep them vids coming. Surely is a big help. Thanks!
great stuff. it was great to see the test. i was really surprised by the results. i'll be extending my tungstens out further, as i used to go slightly shorter stick out than recommended. now that i seen the test, my thoughts have changed- nice work
JSYK, that segment at circa 4 min in had great audio. Even the music. If you had switched to a different piece of equipment, make a note. It works well.
I really appreciate these videos, getting any info from stuck up welders is impossible, it’s very cool what you are doing. 8.8 narrowing was my favorite so far.
Thanks for this info Justin. You always produce excellent videos and I've been doing this for over 25 years now and I still end up watching your videos, Bob Moffat's and Jody's vid's after I get in from a shift. Always learning mate. Keep up the good work my friend. Top Man 😎
12 looks best I think no heat problem thank always learning I started awhile ago couple years about 30 years I started stick and never stopped 1933 Chevy frame to a 1955 Chevy front. End assemble thanks never stop learning thank you
Just learning to tig I purchased all needed to get started watching your vids is very helpful and educational i don't care for the long cups mine came with what number cup is good for a beginner on the short cups im using a 6 on the longer cup now your input is appreciated thanks in advance
I welded a crappy cast exhaust port/flange (Harley-Davidson Shovelhead) with a #10 and a ton of stick out in the beginning, until I got the deep part filled, then went to about 3/8" stick out. I bet I was 5/8" or more in the beginning. I turned up the argon flow to about 35. Don't know if it mattered. Nasty metal.
Very good, well done. We take so much of our welding for granted. Your scientific approach plants a lot of knowledge seeds for future use. Plug me in for the drawing, I'm already a bell ringer.
Really interesting, I really need to see things like this to accept any rules. I really like your channel. I am an Arduino coder, musician and artist and starting to do metal work. Just got a TIG setup for my welder. I was really pleased to find a channel that uses Arduino and welding, I am a fan.
Very good knowledge of Tig welding. I enjoy the video and you sharing your knowledge. I am a welding and fabricating tutor at New Zealand Welding School and good learning new ideas from others like yourself. Awesome.
Would be great to see the effects of a longer stick out while welding into a tight corner, does the gas get trapped and provide shielding? That type of joint is my nemesis, just can't see.
Have you done one of your sweet break downs of why tungsten diameter matters and what the difference and benefits are?I can’t seem to find one. I’m re learning tig specifically thin aluminum and I’m told 3/32 will do everything until you get to the really thick metals.
I only use excessive stick out when welding down into a hole Like a broken bolt or stud below flush. When you drilled all those holes in that block I was hoping you were going down that road.
Ive been welding for years, your videos are really great. You're doing the experiments and tackling questions that i've always been curios about but never followed through. Ive learned a lot. Thank you for putting the time and effort in to spread the knowedge!
You might have wanted to mention less stick out you can run less argon flow, more stickout obviously you need to run more for the required coverage. Running the same amount of gas for those different stickout lengths will obviously give different results due to gas coverage.
So what I'm conflicted with is the HAZ. The oxidation should be an effect of stickout and cfh, but the HAZ (I assumed) is an effect of amps and travel speed. This is relevent to me, as I weld 10g-16 g stainless everyday.
Great video! Really enjoying the CNC welding development it is very unique. I would be keen to know why you chose that specific tungsten height and how some angles affect the weld, as an angle simulates how we handle weld. Cheers 👍👍👍 ps no idea how to find the community tab, but I'm hella keen on a cup 😁
You did not take into account possible impurities that can affect both the bead and the tungsten. When I was taught to weld that's what was drilled into me. Not the weld specifically, but the possible contamination of the puddle or the red hot tungsten.
I would think that gas flow rate also needs a bit of tweaking along with stickout. I do understand from a pure experimental standpoint you want to only change one variable at a time.
You get more accurate data when it's only a single variable. Adjust multiple things and the data becomes inconclusive. Stack data on data by only changing one variable at a time and you get one ridiculously long episode.
Hey Justin I like to thank you for having the kindness to share all these valuable detailed and tailored information man. Today man is going to be the first time ever TIG try to weld something as well as STICK try weld. However I have experience in cutting with oxy/Acetylene. I have a question for you.t When it becomes about the.touches
Due to the relative high resistance of tungsten the greater the stick out the more power is going to be lost in heating up the tungsten and the less power in the arc. So the longer the tungsten the cooler the arc will be for the same settings on the welding machine. The weld heat is produced by the I2R (current squared times resistance)losses in the arc.
Good video as always Justin . Enjoyed the live video with you and crummy the other day that was cool would be cool to see more or that. Thank for video no your a busy guy trying to keep up with everything 🙏👊🏻
I am a noob to tig and was having trouble seeing my puddle, lifting my torch to see the puddle caused major porosity weld issues, watching this helped me realize I didn't have enough stick out, thank you for these videos. Can you do a video on cup size nd argon flow settings, I have basically been using 20 for everything for flow regardless or cup size and it's worked well enough but my stick out has been way to short after seeing this.
O and my stick out was probably not enouf did not know about the stick out thanks i realy get a lot out of your tips iv been welding all my life started stick then brazing the mig
Man if you have time to do the same test again just do it with a single cup, when you lower the stickout size drop your CFH the same percentage as the amount of stickout you use to show the same gas flow say if your running a 3/4" stickout on a number 12 at 25CFH try doing a half inch stickout @ 18CFH or roughly 1/4 less CFH see if the results are identical would be awesome to know also
I've been welding for 40 years and still, as technology charges, learn something every day thanks to people like you.
Shoulda paid more attention in english class.
👍🏻

Didn't have far to go into the comments to find thoughts of the angled torch effect, 1st one. Hope to see a follow up too. Weld done
So thankful that this video doesn't have a bunch of loud crappy metal music as a backing track.
Your testing methodology is quite sound, I'm very impressed. You do a good job of stating facts in a way others will understand and retain. Thank you.
was I missing something or was there no gas flow mentioned in the whole video?
How much gas do you use with 25mm of stick out?!
He covers this in another video. Cup number x 2 = minimum cfh to run.
Yes and also the blanket behind it will help keep coverage over the weld and flow from cup. Argon is heavier than air. And will fill the area as long as it's covered.

Very good, well done. We take so much of our welding for granted. Your scientific approach plants a lot of knowledge seeds for future use. Plug me in for the drawing, I'm already a bell ringer.

Great job! It's a science with lots of variables..thanks for making this video!👍
I'm surprised that the high frequency didn't mess with your CNC machine.
Interesting good to know thanks for setting up your CNC to weld with
So what I'm conflicted with is the HAZ. The oxidation should be an effect of stickout and cfh, but the HAZ (I assumed) is an effect of amps and travel speed. This is relevent to me, as I weld 10g-16 g stainless everyday.
Yeah, I started welding in 1978 and I totally agree with Gary
Great video! Really enjoying the CNC welding development it is very unique. I would be keen to know why you chose that specific tungsten height and how some angles affect the weld, as an angle simulates how we handle weld. Cheers 👍👍👍 ps no idea how to find the community tab, but I'm hella keen on a cup 😁
Many thanks for such excellent advice and demonstrating of skills, is outstanding
Very good illustration it helps a lot and very interesting to be sure...great job
You did not take into account possible impurities that can affect both the bead and the tungsten. When I was taught to weld that's what was drilled into me. Not the weld specifically, but the possible contamination of the puddle or the red hot tungsten.
I would think that gas flow rate also needs a bit of tweaking along with stickout. I do understand from a pure experimental standpoint you want to only change one variable at a time.
You get more accurate data when it's only a single variable. Adjust multiple things and the data becomes inconclusive. Stack data on data by only changing one variable at a time and you get one ridiculously long episode.
When I stick my neck out too far, I usually get into too much heat too.
Hey Justin I like to thank you for having the kindness to share all these valuable detailed and tailored information man.
Today man is going to be the first time ever TIG try to weld something as well as STICK try weld.
However I have experience in cutting with oxy/Acetylene.
I have a question for you.t
When it becomes about the.touches
Interesting comparison. Thank you.
Good stuff. I'm trying to get in Tig as well. Thanks for your videos. Like 👍
Do a review of the TIG finger from welding tips and tricks
"It keeps your finger cool for longer than not having it" is about the only review anyone can give.
Due to the relative high resistance of tungsten the greater the stick out the more power is going to be lost in heating up the tungsten and the less power in the arc. So the longer the tungsten the cooler the arc will be for the same settings on the welding machine. The weld heat is produced by the I2R (current squared times resistance)losses in the arc.
Good video as always Justin . Enjoyed the live video with you and crummy the other day that was cool would be cool to see more or that. Thank for video no your a busy guy trying to keep up with everything 🙏👊🏻
I am a noob to tig and was having trouble seeing my puddle, lifting my torch to see the puddle caused major porosity weld issues, watching this helped me realize I didn't have enough stick out, thank you for these videos. Can you do a video on cup size nd argon flow settings, I have basically been using 20 for everything for flow regardless or cup size and it's worked well enough but my stick out has been way to short after seeing this.
Cup size x2 = cfh
Awesome video very informative!!! I have been wanting to try one of those style cups. And that definitely broke down there uses!!!😀👍💯
Thank you so much! I have learned a ton from your channel . Looking to buy another TIG with AC .
1fastbuggy check out the HTP Invertig 221 that’s what he used it’s a great tig welder
Thanks. Will do now. Keep up with the great video's. And thanks for your reply.
Those size numbers are Army Navy standard, otherwise known as a "dash" designation -6 is 6/16 or 3/8
O and my stick out was probably not enouf did not know about the stick out thanks i realy get a lot out of your tips iv been welding all my life started stick then brazing the mig
Man if you have time to do the same test again just do it with a single cup, when you lower the stickout size drop your CFH the same percentage as the amount of stickout you use to show the same gas flow say if your running a 3/4" stickout on a number 12 at 25CFH try doing a half inch stickout @ 18CFH or roughly 1/4 less CFH see if the results are identical would be awesome to know also
Dude, this vidz are Great, keep up the good work. I only MIG right now but I am using all your videos to be ready for when I get a TIG machine.
I haven’t even watched this but last night I was tigging and wondering about this. So thanks for the video!
