I've been welding for 40 years and still, as technology charges, learn something every day thanks to people like you.

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!

Wow, respect for admitting where you were a little off and setting up a test in such a way that you couldn’t bias it

So thankful that this video doesn't have a bunch of loud crappy metal music as a backing track.

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!

just found your channel. Finally tig tips I can use. Cheers dude.

Just found your channel. Great videos man. Very thorough, direct and to the point. Thanks for taking the time to make them.

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.

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

Awesome video, thanks for taking the time to make it along with all of your other ones.

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.

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

You're a very good instructor. I just wish I could think as fast as you deliver. Very helpful ... Thanks!

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 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

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.

Just got my first tig thanks for this info will definitely look back over your over tips

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

Nice video as always!! Thanks for showing the gauge block, I'm gonna make one for myself cause it's so handy!

Great idea on the depth gauge. Really enjoy your videos.

For this CNC application the straight torch would be IDEAL. Great Video

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 😎

I just bought a tig welder, and am teaching myself how to use it. If I have a question, I search in your videos. Thank you for educating me.

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.

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.

All your video's are extremely helpfully, every time I watch your video's I learn something new. Regards Hugh South Africa

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.

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 👍🏽

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 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👍

Wow! I was lost in a sea of videos trying to find why I sucked and you have me dialled in and on my way. The right way!. Thanks

You have an awesome attitude and are still positive. Keep up the good work

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.

Great job! It's a science with lots of variables..thanks for making this video!👍

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!

Thank you for all your knowledge, Justin

I’ve been wanting that Fupa 12 to try on stainless. Awesome video learned alot

Great video, thank you for posting. This was extremely helpful.

Justin, you rock! Your explanations are very helpful and informative.

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.

I do not weld, I dont own a welder. But I think I will be watching all your videos. They are awesome to watch!

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.

Very informative and easy to follow, thanks and keep the videos comming.

Great vid as usual, think I was using too little stick out on stainless tube, now I will try this aproach next time , thanks

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. 🇦🇺🤜🏼🤛🏼😎🍀🍀🍀

Great video !! You answer me real questions with concrete numbers, very usefull videos for me, congrats!

Cool thanks for the info. Learning to tig. Using an OLD SCHOOL P&H welder.

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

Awesome video very informative!!! I have been wanting to try one of those style cups. And that definitely broke down there uses!!!😀👍💯

Those pyrex cups 🤤 beautiful. That would come in handy for all these firetruck Ariels I work on. Keep up the great videos!

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 haven’t even watched this but last night I was tigging and wondering about this. So thanks for the video!

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 illustration it helps a lot and very interesting to be sure...great job

That's a lot of work for an experiment. Thank you.

Many thanks for such excellent advice and demonstrating of skills, is outstanding

Good info, thanks for doing these tests.

So much to learn from your serie!!! Thanks!!!

Really great advice you give out on this stuff

Interesting comparison. Thank you.

love your videos and want to add on this one ,, repeat the test but with the proper cup per stickout

thanks brother for the time this was a real good test

Great video Justin! I'm just learning about tig welding and you seem to be world class!Wordering how much stick up you run on that hair...Just playing

You've helped me understand everything that I was doing wrong. Thank You

i just started watching you make great vids with really good explanations

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 :)

Your torch has a lot of stick out because it's glad to see you !

Great job... Well worth watching, and very intuitive. Thanks

Thank you so much for this video it's backing up what I've been saying for a long time

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.

I love your videos man, they are so informative !! Cheers on them and regards from Germany

Smart guy. Thanks for the cool tests.

Finally a good video that answers the question.

I agree you're results are very interesting. I run similar stick out to your usual standards, but I'll try a little less on tubing and see how it turns out. Thanks for all your guys hard work, it's help motivate me to get back into fabricating again after a very long back injury recovery from the Army. Oh and just so you know my shop hat is looking pretty prime for a replacement ;-) #loveFUPAcups

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 😁

Nice work! Very informative, thanks.

Interesting good to know thanks for setting up your CNC to weld with

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

Awesome videos as always.great information here!

Good stuff. I'm trying to get in Tig as well. Thanks for your videos. Like 👍

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.

I like your big brother teaching approach.

Well done and very interesting. Thanks.

Dude thanks for everything you share 🙏💯

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.

Great video ! but i kind of miss test of the stickout lenght with the small cup like 8... maybe next time

Just found your channel, enjoyed the comparisons and learning from you. Subbed and belled.

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.

Your videos are very educational and informative. I have working experience with brazing and pipe sweeting. I am interested in getting back to tig welding. It's been years since I last used a tig. I will be purchasing an AC/DC tig from harbored freight. But, should I use the peddle or non- peddle option?

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.

As a new comber this is some awesome info. Gotta get my welder up and running. I come from a stick welding so this is going to be interesting lol. But luv the videos!

Just learning how to dig, this was helpful

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?!

Great tip on the stick out block.

So I am watching this video and thinking to myself "There's something missing" Then it hit me. There's not enough welders in frame. There should be no less than 50 welders behind you. Get yourself together man.

Very helpful for a beginner! Since I’m a beginner. Thank you

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

Very interesting video. Many thanks.
