What a different way to approach the issue, I was bringing up the heat slowly until I first got the Puddle needless to say I was putting in way to much heat. Time & travel speed effects the heat input more than even the amperage setting, it's like a light just went on in my head, thanks.
Enjoying my morning coffee and figured I'd prepare for the day ahead by watching some instructional videos. I'm just getting in to TIG (I've done MIG and pulse MIG for nearly 15 years in a part-time production environment) and I'm so glad I landed on your videos. Very clear, concise, and informative!
I'm just so glad you put your years of experience up for us to see. You could have compiled your own coursework and sold it to schools. You could have STARTED your own school. You could have kept only to the lecture/guest educator circuit. All these things would have made you crazy rich without reaching the audience you do here. Thanks man. (P.S You can still do all those other things but please dont stop the videos :D)
Schools actually recommend to watch his videos...mine did and a lot of young You tubers mention his videos....old welders can make stuff look really easy lol
A real treat watching you chase that puddle at 160 amps. Amazing what a reduction in HAZ there was between even 140 and 160. Clearly, we're dealing with a non-linear phenomenon.
Hearing you talk about the heat transfer made me think of something I learned about lampworking. That's welding glass tubes and shaping them. As you heat the glass it's helpful to think of it as water flowing into a dry sponge. The longer you sit in one area the deeper it soaks. In glass you have to keep it moving or it will drip like honey off a spoon. In your case 80A had to soak more to get hot enough and that soaked more heat in to the surrounding metal. Anyhow, good stuff 10 years later.
im a mechanical engineer. everytime i watched your video i always wanted to dive into welding practise and try your techniques and etc..😊 this is really educational.
WOW! Huge difference in the look of the weld at 80-140. My instructor told me to turn my heat to 60 on 1/8" stainless steel, and I must admit it took forever to establish a puddle. I'll try to turn my amperage between 90 -100 tomorrow and use this technique
Somehow , you get a perfect focus on your puddle , and this makes it easier to understand just what you are trying to get across to us . I appreciate that .
Great video Jody . The wife came out to the shop and I showed her the tig finger and she took exception to it's placement on the particular finger it was placed. I just had to say that is how Jody does it and then it was all good. Thanks
I just wanted to say I appreciate your content it really helps. All the data you include really helps. Filler size tungsten using multiple amps and materials and how you lay it.
Jody you're a wizard sir, you make this look so easy. finally got the power line run for my tig machine and I've been trying to do your "steel drill" for the past two evenings. to say I have a lot of practice to do would be an understatement. thanks for your videos
As always, a great and very instructional video. To the point and well put across. Thanks too for not assuming that everyone lives in the US. You have a worldwide audience where most of us use metric!
What you demonstrate in this video is a daily ordeal at my job! I weld aluminum floors that are sometimes up to 28 feet in length with 8 seams that get fully welded. If you run to cold, you basically warp the entire floor. Hot and fast is the only way to do it. It's all push pull of course, TIG would never be practical. Thanks for the hard work you put into your videos man, keep it up.
Thanks, Jody 😊. I'm basically a novice when it comes to tig welding. Was having issues last night trying to tack up a new welder cart, I believe I was long arching causing my tungsten to constantly lose its point 😒. After dipping my tungsten half a dozen times (but in my defense, I was on the dirty, crooked floor trying to get a nice square joint 🤣) guess I was overcompensating. Thanks again man 👍😊👍. Cheers!
Of all the videos I've watched on welding this is one of the best. I just got my first tig, a Dynasty 210 DX and thanks to you and Mr Tig I have ben putting down some good caterpillars. 😎 Thanks Jody
Thanks again, you really get to the nuts and bolts of the operation and makes it easy to understand the reasons why you are showing the methods to use.
I use and like a tri mix tungsten, can't say I've seen any of your videos using different kinds of tungsten. PS keep the video coming your a bank of welding knowledge that I greatly appreciate you sharing. (Tig finger genius!)
thank you very much for this excellent lesson, I think showing less heat by increased speed is very helpful and you did an excellent job. details like larger spark is higher voltage helps me a lot and I do need help.
I was just explaining this to a UA-camr that bought a 3 in 1 Mig Tig and Stick for his car restoration, this video will probably be twice as effective as my explanation
Hi Jody. Really like your videos, ive been tig welding for a good few years now and I still learn something from your videos. Could you do a video on how to deal with porous welds when welding mild steel? Even when properly preped I still get abit of porosity occasionally and its very frustrating. I doubt I'll be the only one who suffers this problem from time to time.
Just got started with TIG welding. You videos are excellent. Thank you for putting them together. I'll look at your store to see if I can express my appreciation in more material ways. :)
On the tube mills that I’ve worked on. Both carbon and stainless the seams are joined together using a coil on carbon. steel as the seams are mashed together and a skiving blade right after to shave the the top weld off. As for stainless a laser is used right at the point of seam contact to mash the two together. Carbon runs anywhere from 160fpm to 300fpm. The best we can get out of stainless because of the annealing process is about 30fpm.
Those tig fingers r good Jody I must say I like em I do a lot of tig. I find it helps if u wear a heavier glove like a mig or stick glove on that torch hand your puting it on it fits more snug. If u could make a smaller size one that fits snug on a tig glove would b good. U want it snug n they r a little big if u use it on your pinky finger like most prob do. Otherwise handy little things. For others using em they do fray with use over time but if u have a flap disc\ sanding disc they last quite a bit longer if u give sharp edges a little sand to remove the sharp edge.Sheared edges or burred edges chew these things up pretty quick. But once again these things r very handy. Always got one in my box!
These are awesome ! I picked up a TIG after doing a little research for my body shop. A lot more aluminum is being used in the bodies, and they have to be welded. In steel bodies, the metal has gotten thinner so the old icy-acetylene torch with fluxed brass or copper clad steel rods are out due to warpage. On the thin steel I've laid a wire from my MIG as filler and welded over it. Leaves a nice flat surface with very little grinding. My question is this: can I use this lay wire technique with aluminum?
Damn, wish I had seen this video a few weeks ago. I just got done finishing an exam piece and was running 50 amps on a v-butt, outside corner and T-fillet, with anything higher I just got undercut no matter how much filler wire I put into it. Got it done in the end but was sloooow going. Great video as always.
I know this video is very old but I would love to see this test done without a gas lense with maybe a regular #7 cup. take a look at the fabrication series video that shows how the gas lense changes how the heat effected zone looks
When dipping the welding wire into the weld pool do you just keep doing it rhythmically, or can you actually see when it needs to be done. Thanks in advance Stuart
Awesome video as usual! Tons of great knowledge and info. And for those that TIG weld, and don't have a TIG Finger yet, get one....or 2 or 3...worth every penny 10 times over!
Love youre videos...I'm currently a student struggling with tig..in youre opinion is laying the wire a stronger better penetrating method than the dime method?
I don't think I have missed one of your videos as yet simply because you are so straight forward and to the point with some humour. At this point I was going to praise you quite a lot but I want you to still be able to fit that mask over your head. I do however have a question about the TIG finger .... would it also be suitable for use with a MIG welder in a case where there is simply nothing to steady against other than the work piece with the left hand little finger and the right hand steadying on the left hand, so essentially the TIG finger would be worn on the little finger of the left hand and pass approximately 3" away from the welded joint and approximately 7" from the active weld? Please keep on posting so that I can keep on learning. Allan
Use the TIG finger for MIG welding? I do it all the time. but here is the thing... if you hold the tig finger too close to the mig arc, like 1 inch away, it will definitely start fraying.
As always awesome video Jody my skills have come a long way since I started watching and I actually passed my first test first time and you have a little to do with that. Also your DVD is going to make a good addition to my collection
can we apply this to thinner gauge steel/ alum. and what applications such as cups, lenses travel speed and amps? ive gotten into the sheetmetal industry and i need some insight, Thanks for all the vids Jodi
Love those video Jody, still trying to get it down. I am having better luck with aluminum than SS. I think my arc is too long, because I am having a horrible finish with lots of porosity and too much heat discoloration.
At the end of the video you touched on heat spread affects on aluminium welding. Repairing structural things like aluminium boats, can they be welded without bad HAZ effects?
Hazzy238 Aluminum will always suffer from a loss of strength in the HAZ. You can minimise this loss in strength but never eliminate. When you think of welding structural aluminium jobs remember to consider the strength of the joint will only be 2/3 yield of base material rule of thumb.
do you have any videos that show tig welding on very thin ferrous and non ferrous metal. range from 24 to 12 gage sheets. or will they vary on different techniques?
Please could you tell me what material you use for the filler wire on cold steel. Here in Hong Kong they are telling me to use 316 Stainless steel filler rods and they are selling for $750 per 5 kg ...owch. The other option they gave me was just use a STICK welding rod WITH the gig welder to join two pieces of cold rolled steel 5mm thickness together :-)))) Hmmmm sounds dangerous. What do I need the filler rods for? Im welding could pressed steel 5mm together to make a TIG trolley. Please could you shed some light as to what material the filler rods should be! Thank you Richard
great video joey. ive been following for awhile now. i just got a great job in beaumont texas working at Ohmstede. making heat ex-changers. using tig, mig and stick applications. im looking for some vids for a little thicker material. say, 3/8ths. all positions. i need one of those tig fingers also haha. but yes. which one would be best to go by. lately ive been using 316 filler and 410. along with some 2205. i want some a better stack of dime, all positions
Love your videos. As an R/C Heli instructor, explaining things in understandable detail is your forte. OK, I'm on my second "m" size bottle of argon just doing bead line after line, with and without filler. However, try as I may I just can't my fillet weld the color and small weld size of your fillets using the same steel as in the video. My amps are 120 with 1/16" 1.5% lanthanaded rod, wp9 torch and my time for welding 3" is right around 35 seconds. Before I pull out what's let of my hair, can you help? Thanks for your effort, Pete O
My second charpy test piece past today ironically. I had to do stringers as apposed to my normal weave or j technique. And yes I did cheat on the travel speed. Lesson learned! Didn't think these things were so important. Thanks for this lesson
weldingtipsandtricks Im actually glad it failed cause it lets me know that I have been doing it wrong for a long time! Thank you again for your commitment to welding and sharing your knowledge!
What material did you weld on and what was the difference between weaving and not weaving measured in joules? Also interrested in what the bar for passing was set at.
InqWiper The material was SA 516-70N. It doesn't seem that critical seeing as its all rusted and pitted very badly. Sorry I don't know the passing level measured in joules but we did the next test with stringers and it passed. Personally, I think its all BS. Our first test piece was sent to a lab in Pennsylvania and passed with flying colors and I weaved the root and some of the filler. The next 3 that failed were sent to a different lab in Houston. Im not the best welder but I have never had a problem with a weave as long as I stayed within the interpass parameters. If you think about it, weaving does require a slower travel speed inputting more heat. I hope this helped somewhat.
D Armstrong I'm no expert and not familiar with ASME but looking up the material online it doesn't appear to be that sensitive regarding heat input. You say the material was rusted and stuff, did you weld on top of it or did you try fixing it up first? I would not be surprised if it was a material quality problem if you welded on a rusty and overall poor piece.
Enough pedal over a time difference does make a large impact on the strength, geometry & composition of the weld. As Jody states, heat input isn't necessarily a BAD thing. You need to weld 'hot' enough to get great penetration.
Given that your arc length was nearly the same, the heat input would be 4,800 amp-seconds at 80 amps and half that, 2,400 amp-seconds at 160 amps. Good video lesson.
Perfect instruction. Question. That DVD contain the same video that you have on youtube? I mean If during the yeas as a subscriber I watched all your videos, will I find anything new there/
Jody Great Job really appreciate the info and yes the tig finger has saved me many times My welds don't look that good but the tig finger helps me stay on track thx art
Jody i love the new tig finger but I'm still waiting on u to review my machine .I'm wanting to see what a pro thinks about it .its a thermal arc 186 ac/dc with foot pedal
is it just me or is it actually therapeutic to watch TIG welding videos ?
It's therapeutic to lay tig welds aswell ... tig welding saves lives....because we break off as independents and don't have bosses to kill.
What a different way to approach the issue, I was bringing up the heat slowly until I first got the Puddle needless to say I was putting in way to much heat. Time & travel speed effects the heat input more than even the amperage setting, it's like a light just went on in my head, thanks.

You could have compiled your own coursework and sold it to schools.
You could have STARTED your own school.
You could have kept only to the lecture/guest educator circuit.
All these things would have made you crazy rich without reaching the audience you do here.
Thanks man.
(P.S You can still do all those other things but please dont stop the videos :D)
jon arbuckle. yup.
Schools actually recommend to watch his videos...mine did and a lot of young You tubers mention his videos....old welders can make stuff look really easy lol
A real treat watching you chase that puddle at 160 amps. Amazing what a reduction in HAZ there was between even 140 and 160. Clearly, we're dealing with a non-linear phenomenon.
Thanks to Jody I'm well on my way on getting my D17. 1 certification fusion welding for aerospace applications.
GOD BLESS YOU JODY!

This man reminds of my favourite teacher, genius of an instructor that can’t be taught at teaching school, gifted.
I've learned more about Tig welding watching this guy than I did in school by far the best instructional welding videos out there
im a mechanical engineer. everytime i watched your video i always wanted to dive into welding practise and try your techniques and etc..😊 this is really educational.

I just wanted to say I appreciate your content it really helps. All the data you include really helps. Filler size tungsten using multiple amps and materials and how you lay it.
Impressed with this video. Every tig vid teaches me something else I should know. Week 5 of my year long course, improving little by little.
TIP FOR YOU WHO havent bought the CD's.... Its a must have!!!! I gave it a try and man it makes stuff go way easier than I thought. Well made !
Jody you're a wizard sir, you make this look so easy. finally got the power line run for my tig machine and I've been trying to do your "steel drill" for the past two evenings. to say I have a lot of practice to do would be an understatement. thanks for your videos

Thanks again, you really get to the nuts and bolts of the operation and makes it easy to understand the reasons why you are showing the methods to use.
Just bought 2 tig fingers I cant wait to try them out, they will be a huge help getting CWB tickets!!!

This is one of your best videos in my opinion. You and your tig fingers rock!
I have purchased 2 TIG fingers and a XL. Love love love them

Okay. Finally sold me on the tig finger. Great video as always!
Your the biz jody, just want to say. 40 yrs welding never done a lap weld.
Damn, wish I had seen this video a few weeks ago. I just got done finishing an exam piece and was running 50 amps on a v-butt, outside corner and T-fillet, with anything higher I just got undercut no matter how much filler wire I put into it. Got it done in the end but was sloooow going. Great video as always.
Another great video, Jody! I finally ordered a TIG finger...can't wait to try it out.
hey thanks, I cant wait to here what you think about it.
Love my tig fingers! I often use the xl one across my knuckles on my support hand when mig welding
All the video's are great....and the TIG finger is GREAT!
I know this video is very old but I would love to see this test done without a gas lense with maybe a regular #7 cup. take a look at the fabrication series video that shows how the gas lense changes how the heat effected zone looks
The key to controlling heat input is higher voltage and borderline current. Voltage is also the key to better quality welds.
When dipping the welding wire into the weld pool do you just keep doing it rhythmically, or can you actually see when it needs to be done.
Thanks in advance
Stuart
Superb video, you’re very good at teaching.
You the man Jody! Love your vids!
Got me 2 XL and 1 L TIG finger!👍
Great video thank you for being an excellent teacher and an expert.
So I'm about to order my first TIG finger and I want to know how long they last, should I get more than one?
Awesome video as usual! Tons of great knowledge and info. And for those that TIG weld, and don't have a TIG Finger yet, get one....or 2 or 3...worth every penny 10 times over!
Sr You are just a legend!! Thank you for all your videos
This guy is a national treasure!
Love youre videos...I'm currently a student struggling with tig..in youre opinion is laying the wire a stronger better penetrating method than the dime method?
What sort of camera/lens/shade setup do you use? Your close-up arc shots are amazing.
Good explanation about travel speed and heat. Love my Tig Finger, before using that I was stopping too soon due to the heat
I don't think I have missed one of your videos as yet simply because you are so straight forward and to the point with some humour. At this point I was going to praise you quite a lot but I want you to still be able to fit that mask over your head.

Beautifully explained enough to understand.
Beautiful welds! You are very straight forward, very informative tutorial.
Can you show this welding on thinner sheetmetal?
As always awesome video Jody my skills have come a long way since I started watching and I actually passed my first test first time and you have a little to do with that. Also your DVD is going to make a good addition to my collection
can we apply this to thinner gauge steel/ alum. and what applications such as cups, lenses travel speed and amps? ive gotten into the sheetmetal industry and i need some insight, Thanks for all the vids Jodi
Jody, love your channel. Please keep them coming.
Great video Jody, as usual.. I always learn something new from your videos. Thanks!
Love those video Jody, still trying to get it down. I am having better luck with aluminum than SS. I think my arc is too long, because I am having a horrible finish with lots of porosity and too much heat discoloration.
At the end of the video you touched on heat spread affects on aluminium welding. Repairing structural things like
aluminium boats, can they be welded without bad HAZ effects?
Hazzy238
Aluminum will always suffer from a loss of strength in the HAZ. You can minimise this loss in strength but never eliminate. When you think of welding structural aluminium jobs remember to consider the strength of the joint will only be 2/3 yield of base material rule of thumb.
Hi Jody while TIG welding what's a different's while you yousing continues HF vs were just strice arc with HF? while welding
What tungsten rod do you prefer to use?
Thanks so much for this video! However what is the rule for welding dissimilar width material like 1.6>3mm mild steel, what would you set the amps to?
What does "using tight arc" mean? Just getting closer to the arc with the tungsten?
Man I want to tig weld now. Gotta get me that new everlast welder that I have been looking at. Can't wait to make arcs.
Hello there tig welding steel platting a side each other not stepped on ... how do u make yur heat the same as u cant make such pool.
do you have any videos that show tig welding on very thin ferrous and non ferrous metal. range from 24 to 12 gage sheets. or will they vary on different techniques?
Please could you tell me what material you use for the filler wire on cold steel. Here in Hong Kong they are telling me to use 316 Stainless steel filler rods and they are selling for $750 per 5 kg ...owch.
The other option they gave me was just use a STICK welding rod WITH the gig welder to join two pieces of cold rolled steel 5mm thickness together :-)))) Hmmmm sounds dangerous.
What do I need the filler rods for? Im welding could pressed steel 5mm together to make a TIG trolley.
Please could you shed some light as to what material the filler rods should be!
Thank you
Richard
great video joey. ive been following for awhile now. i just got a great job in beaumont texas working at Ohmstede. making heat ex-changers. using tig, mig and stick applications. im looking for some vids for a little thicker material. say, 3/8ths. all positions. i need one of those tig fingers also haha. but yes. which one would be best to go by. lately ive been using 316 filler and 410. along with some 2205. i want some a better stack of dime, all positions

My second charpy test piece past today ironically. I had to do stringers as apposed to my normal weave or j technique. And yes I did cheat on the travel speed. Lesson learned! Didn't think these things were so important. Thanks for this lesson
glad you passed. it sucks to fail a weld test. even if its a material issue and not in the actual weld metal
weldingtipsandtricks Im actually glad it failed cause it lets me know that I have been doing it wrong for a long time! Thank you again for your commitment to welding and sharing your knowledge!
What material did you weld on and what was the difference between weaving and not weaving measured in joules? Also interrested in what the bar for passing was set at.
InqWiper The material was SA 516-70N. It doesn't seem that critical seeing as its all rusted and pitted very badly.

Jody,
Thanks for all the videos. Helps me teach my students.
Ran those tube mills for years started with a twin tig head at 9fpm then went to lasers at 20fpm on stainless
Is heat input synonymous with potential for damage to the material?
Enough pedal over a time difference does make a large impact on the strength, geometry & composition of the weld. As Jody states, heat input isn't necessarily a BAD thing. You need to weld 'hot' enough to get great penetration.
If you’re tig welding stainless, there is a greater potential that the material will break down
Can you please tell me how I could use your TIG finger heat shield? Please send me details. Thank you.
thanks for the lesson Jody...you're the best PROPS!!!
Does this hold true for stick to an extent
Given that your arc length was nearly the same, the heat input would be 4,800 amp-seconds at 80 amps and half that, 2,400 amp-seconds at 160 amps. Good video lesson.
Wonderful as always. You make it look sooooo easy.
Just a small physics point here about the heat spot at 10:00 - air is a poor conductor of heat relative to your metal table.
What welder do you use for most of your tig videos
hi Jody if your 26 th torch how many ams it's rated if my 18 th torch could handle 400Amp
Perfect instruction.
Question. That DVD contain the same video that you have on youtube? I mean If during the yeas as a subscriber I watched all your videos, will I find anything new there/
i always welded @ 130 amps for 2 mm stainless steel and it feel good when you use to it
Hi, love your work and procedure❤ Harrington.
how much is the tig finger, i'm leving in vietnam, how can i get it?
Jody
Great Job really appreciate the info
and yes the tig finger has saved me many times

thx

Another great video - loving my TIG finger XL (Big hands!).
Jody i love the new tig finger but I'm still waiting on u to review my machine .I'm wanting to see what a pro thinks about it .its a thermal arc 186 ac/dc with foot pedal
Appears to be 1/16 filler? Or was that 3/32?
My steel after welding has a large effected zone and gets red hot every single time. I'm not sure where I'm going wrong.
What tungsten do you use for stainless? awesome vid!
