Hello all,
I'm considering the purchase of a plasma cutter to cut complex shapes from copper sheet. Thickness range of interest is 0.020" to 0.125" (~0.5mm to ~3mm). Most cutting will probably be 1/16" (~1.5mm) and below.
I've perused the archive and found folks generally in agreement that this is a reasonable thing to do, but I do have a few specific questions based on what I read.
- When cutting copper, how close should I expect the experience to be to claims that plasma cutters "cut steel like a hot knife through butter?" Visions of tacking a (non-conductive) template to the sheet and slicing away are pretty appealing, but does it really work that way??
- For cutting copper, how much should I derate the mfr's claims of capacity? Can I get away with one of the little 110V, internal compressor models, or do I need more juice?
- Can I get a clean edge without lots of melty bits...err..I mean dross on the cut?
It would be great to hear from folks who actually plasma cut copper, but, of course, any and all advice is greatly appreciated.
Thanks and Regards,
Tom Colson
