At the school I taught at and our shop we have had every brand of plasma cutter, Lincoln, Miller, Esab, ThermoDynamics and have had the best luck with Hypertherm. They have given us the best performance. I know they are not red or blue but they work.
Hypertherm seems to be the one of choice from what I've seen. I have a 600 on my Plasmacam, never missed a beat. Use OEM parts and clean DRY air. My thoughts haev always been to buy the best I could afford even if they don't match color or make. Like a Milwaukee grinder, Dewalt miter saw, Stihl chainsaw. My reasearch shows Hypertherm wins on this one.
