I am getting a new plasma cutter. I have decided on HyperTherm ONLY. I have a Victor smoke wrench for big stuff now, and am considering this for small stuff, including some 20somethingish gauge paintlock, which I shall shape into sculptures and works d' arte.
I was wrestling with what size to get. I tend to overbuy on stuff, but I think with this, I can go with what I need. The larger ones need more air, hence bigger compressor. It already looks like I'll need a compressor to go with this anyway. There is a huge difference in price for each jump in capacity, so one of those jumps could easily pay for the compressor. I would be doing a lot of cutting, so wonder if a 30 would be hearty enough for high duty cycle. Or would a 45 be better, or just overkill, which I like?
How about used units? Are gently used units a good risk? Is there a lot that goes out on these things when used correctly?
I would have to say that one with 3/8 capacity would do the work I want to do, and for all the extra money, I can live with my gas rig for thicker cutting.
TIA
