heat treating is not that complicated. Stick it in an oven at 990 degrees until its thoroughly heated (depends on thickness) quench it. Then stick it in another oven at 320 for 18hrs. Here read about it

it isn't that easy but it can be done. you would have to buy a step down transformer, then make an adapter that picks up only two legs of the 480 3P to connect to the transformer then plug your machine into the output of the transformer. I can give more info if you really want to do this but i sugge...

there is no way that was done with a spool gun. you can see where the a/c arc, from the tig torch, cleaned the aluminum oxide on both sides of the bead. the reason highdezman's practice weld doesn't look more like it it cause his puddle was a little hot and it all flowed together. To be sure though ...

I'm thinking (which is dangerous) that the torch is moved left to right and slightly forward adding filler when torch is to either side. Helps when you need wider bead.

the reason people are using lanthanated instead of thoriated is because there is some concern about the dust when grinding thoriated since it is radioactive. i think Jodi says " That this is the one time the fix is better than the original". there are enclosed wet grinders that capture the...

I just started TIG school last Monday myself. One of my instructors happens to be the Admin of this site. He also instructed me in MIG last year. The tungsten melts in DCEP because current flows from -to+ so the current is going from part to be welded to tungsten. Which heats it up. In DCEN current ...
