Shane I'm full blown diabetic I just rest the heel of my right hand on the object and use my left to help me move and keep it steady. So Far I'm all self taught but I'm registering for classes in DEC. and start in Jan. Welding and fabrication. Good luck and take care of yourself before it goes full blown. Link you rock even if you can't spell post some more videos.

Im in welding class in high school... and yes oxy welding is a good skill to learn before you tig... tig sucks when you weld alum. cuz when you contaminate it and have to start over and ball the tungsten up again..

It's not all that bad to do really. Most likely, you didn't do much of it, or didn't have somebody there to show you a couple things that could have made a big difference for you.

I spent years welding that stuff, and it's really pretty easy to weld when you get used to it. It's not as sensitive to heat as stainless is.

And for those that use the term "arc welding".... tig IS arc welding, Mig IS arc welding, stick IS arc welding... Oxy-acetylene? nope, guess why.. cause there's no arc there!!

Why bother? DOT certifications are pretty much useless. Look up the DOT specs and they really aren't ----. Go for at least AWS certifications, if you're getting them on your own or through a welding class. Then, when it comes to working for somebody else, ASME certifications are the best ones to get.
Also, if the DOT specs are similar to ASME or AWS specs, speaking of material thicknesses, your 1" test will only certify you to weld something like 1/2"-2" plate...which is not very useful. 3/8" plate will certify you to weld thicknesses that you are more likely going to encounter.

You don't have to learn to stick weld before doing tig welding. I taught welding for quite a while, for Heil trailers. They didn't do any stick welding. It was all mig and tig. I found it didn't make much difference whether they did mig or tig first, even. I had pretty good success teaching tig welding to people that had never seen an arc before. I had guys that could pass AWS tests on aluminum within a week or two.

Nope...just break the dirty tip off, or grind it clean. Leave it broken on the end, or grind it a bit blunt, and go back to welding. It will get round again on its own ir you're welding hot enough.
You will very seldom see professionals do the old copper block and switching polarity thing to ball up the tungsten...unless they either like the habit, or are doing xray work.

well the 3/8 stuff is easy anyways. I passed that with ease. I would agree that 1" is not going to be used as much by anymeans. But my instructor seemed to think it was a pretty big thing. I actually just tried a 1" test on tuesday just for the fun of it,but I was kinda in a rush to get it done and ended up getting it a little bit to hot and it crystlized in the metal. It broke at 10 tons. So I guess I will have to work on that. I actually have got a 3/8 plate to bend complety in half. It was not xrayed though but I think that is would have passed that anyways. well no more classed till January kinda sucks but at least I will have some time to practice in between times.

In many schools, they like to run you through all these certifications because they charge you for each one. It's a scam. 1" plate is easier to do than 3/8" plate because you can weld it hotter and decrease the chances of lack of fusion or slag inclusions.
What interpass temperature does the procedure call for?
If you havn't seen a procedure, you need to ask for one.

pics are coming this weekend promise. lol borrowing my dads camera
