A friend made used a plasma cutter on some heavy steel plate. Comparing this thing to a cutting torch is like comparing a fillet knife to a meat axe.
Question: Anybody know why these things are still so danged expensive? The cheapest ones only have a 30% duty cycle and are still more than $500. It would seem that this will be the next big Chinese import??
Is anything burned or used up on these machines that is outrageous to replace--or do they simply get the job done with an electric arc and air?
