[TheForge] cutting 1/4 copper

[Kevin D]

Gawd that sounds wonderful :)  Imagine I could spend $2000 converting an old
welder, ha! (given time and expense)

 Kevin, a long time ago (8 or 10 years) I bought a L-TEC brand plasma
 cutter. It is adjustable up to 40 amps.
 It was very expensive for me then, something like $2k. It has paid for
 itself many times over.
 it will cut up to 1/2 " steel (but not the best looking cut) It rips the
 hell out of 1/4" copper plate though.
 Don't know about being to convert your stick welder over. I think that
 there is a whole lot more to it than that.
