have a straight AC-only thunderbolt now. "not so great" on thin stuff,
like 2x2 by a sixteenth wall sq steel tubing. I get 'burn through' too
often to suit me. would an AC/DC model of the same machine be any better
on THIN stuff?

I realize a mig setup with a gas bottle would 'for sure' be better, but
there's an AC/DC thunderbolt used nearby...

thanks for comments, guys
