On the note, I picked up a diamond coated cut off wheel for a 4-1/4" angle grinder. We did a ton of cutting on everything from 1/4" wall tube to sheet metal while building a race car over the last few months. It lasted at least the same as 30-40 abrasive cut off wheels. And again, no stink and smoke and no busted wheels. Highly recommended if you use cut off wheels a lot.
A plasma is on my list. What is the difference between scratch start and HF start? Is it the same as the old scratch start tig welders?
I wonder if anyone makes one that can use a TIG/stick welder as a power source? I have an giant old L-Tec Heliarc 306 in great condition that I could use for a power source if someone makes such a beast.
EDIT: I just did some research, it could be done, maybe, but cheaper and easier to buy a plasma cutter...
