Do I. AC/DC arc, Mig, and Oxy/Acetylene. Kind of part of the deal growing up.
Comes in handy now, I just finished today at work custom making a hanging rail system in a van for the guy that delivers drapes. Made it out of Unistrut, 1" iron pipe, and lots of sticks.
Also made this last weekend with the home ac unit. It's the reason I will have to take the crossmember out of the hotrod and modify it to allow dual exhaust. I could borrow an engine stand, but it's probably going to be a while before I'm ready to install it, so I just wanted a little cart I could move it around the garage on. I havn't cleaned the weld spatter or painted it yet, I'll do that to sell it after I take it off the motor when I put it in the car.
