How to Weld Thick Metal With a TIG Welder - Kevin Caron

- From www.kevincaron.com - Artist Kevin Caron welds hardened railroad spikes with his TIG welder ....
Caron is setting up his new Everlast PowerTIG 251Si multiprocess welder for TIG welding some railroad spikes. He's working on one of his Shitake Agaves, so he thought he'd give the welder something heavy to chew on.
On the panel, he has it set on high frequency start, standard TIG - no pulse - 150 amps, and 4T because he's using the welding torch trigger instead of the foot pedal. He's set the welder to 1 second of upslope and 1 amp to start, 1 second of downslope, and 4 amps to stop. He pushes the button to put his settings into preset mode, and he's ready to go.
Why is he using TIG welding for this project? He wants to check out this new machine at some higher amps to see how it does, test the cooling capability of the machine, and to see if he can hit the duty cycle. He also likes TIG welding because it's clean, basically smoke free and quieter.
If you look on his workbench, you can see the mess he made when he was using this welder to MIG weld the base of the sculpture. There's lots of spatter and debris you just don't get with TIG welding. With TIG, you get a nice clean weld - a nice clean joint so you don't have to clean it up. That's helpful with this part of the sculpture, which is sticks up above the base and will be more visible, so he wants nice, clean welds. He used the MIG welder for the structural, unseen part of the sculpture.
Caron puts on his safety equipment and tacks the two railroad spikes together. The tack looks pretty good, although you can see where the gas hadn't quite purged out of the torch at the beginning. He runs another bead on the side of the spike and is able to get a puddle going. He says he probably could bump up the amperage a bit from 150 to 165, but he gets a nice looking bead with no holes or porosity - just the way it's supposed to turn out.
Lessons learned: be sure you get all the rust off the metal to get a good, clean solid weld. Also, the machine seems quite capable of welding heavy metal.
Caron is ready to get back to working on this sculpture, so you have time to go to www.kevincaron.com to see more how-to videos and his wild work, and to "like" him on Facebook at / kevincaronstudios
Well, you might want to stick around just to see why you need to switch those cables when moving from MIG to TIG welding ....

Hey Kevin... I'm glad to see that even professionals make the occasional "blooper". I've just begun to add MIG and TIG welding equipment to my existing stick and oxy-LPG equipment so have found your videos very useful. Love the website too... you have some great stuff over there.
Awesome thx!
Learned mig from ya, getting better at tig now too... Work in progress.

That is awesome!
I went over to check your website finally last year. You got some great works. I get great ideas when riding my motorcycle as well. I'm just finishing up my diploma and love to tig. I have a question though. You said in another video that you never took welding classes and I'm wondering how did it take you to learn get settings right? Ok well, thanks for your videos, they're always insightful and entertaining.
Thanks for sharing Kevin 👍👍
No problem 👍
Did u ever make a video on what size rod to use with what size material being used ?
how do I calculate the amps on different types metals?(stainless, iron.....)
what happens if you use more amperage then you need?(hot)
would I make a hole on the surface or break the machine?
I just go with 1 amp per 0.001 of metal thickness.. adjust as needed..
If you go to hot on amps yes, you can blow a hole through the metal. But I don't think you can break the welder.
It's why I prefer TIG also, clean weld, no messing up my workspace. And no hot metal getting inside my clothes!
Or the spark in your ear!
I'm building frame work fit machines..... kind of vague .... I know... mostly 3/16th and below.. I about to pull the trigger on a new MIG welder ..,. should I be rethinking this ?
I always wonder if fit sound be good for structural and home repair type work..... any advice?
I would go with tig for that thickness. Much easier in my opinion.
Model number just rolls off your tongue. :-) Lots of settings, whew!
+C Crosby I practiced. ROFL - I was reading it off the panel. The settings get easier as you work with it and are well worth learning.
+Kevin Caron, Artist---Hey Kevin What the heck are you doing? Mary LOL ..
Hi kevin great tips and advice!! I have a lincoln invertec160tp but the front and back of the tig torch have gone walk about.... Would you happen to know if the tigs are all generic sizes or specific to each torch? A long shot i know but thank you in advance. Aus
+Dubstep Look on the side of the torch. there will be a number and a letter.. get the same size. Should fit no problem.. Or just get a whole new hose with torch to fit that machine.. Check with the folk at CK torches.. they will know what fits that machine..
+Kevin Caron, Artist thanks a million mr caron!! Cheers
Awesome! :D
Where did you get the arm sleeve protectors? I like the look of them
+Sheldon Otto Goggle "heat sleeves". Found some on Amazon. These came from tigdepot.com
So can tig welding be considered for structural welds? Or is it just a way to glue to pieces of metal together without all the clean up.
+TinManKustoms Most certainly used for structural work. Like power plants, refinery's and so on...
I understand the yellow flap on the front of your welding helmet, protect your neck from the UV, but what is the white fluffy thing on your headband? Is that a mega sweat absorber, or is is something else? I ask because I have the problem of the lights in my shop causing a reflection on the inside of my helmet making it hard to see the welds, I have tried moving the lights, but, you need lights, so I still get the reflections, but I was thinking of a flap on the top of my helmet too...

+StuInTokyo Big sweat band!! It's regularly over 110 degrees in the shop this time of year..
Thanks Kevin
Kevin I am one of those starving hobyists i have a second hand Lincoln flux core 90 amp welder. Is there a way to use this for thicker metal like what you are welding
+Robert Merrick Sorry but no... Without adding more amps to the output you just can't do the thicker metals..
Yes!
Preheat your steel and grind the corners off your steel then run 2 passes with a broader pass on top.
The heat from your welder is being quickly wicked away by the steel.
The first pass will hold and super preheat the steel.
The second pass will ensure your welding on really hot steel and therefore bite in deeper.
Also flux core welding is best done inside or on a windless day.
have you ever made anything with premade Damascus billets?
+Sylvan Energy Solutions Tried to make my own one time.. Don't know enough about blacksmithing to do any good with it.. Just made a mess....
Oh ya, you forgot to call...lol
Looks good, but should use a gas lens instead of the collet set up, but great work man.
+Thomas Wilson
Thanks, have to buy another set of gas lens I guess..
it happens right...
Was anyone else reminded of GoT by the work piece?
!
Thanks for watching and posting.
Now break it and show where it broke.
You should have been here earlier!
Typical artist personality
Thanks, I think.
