As some of you may remember, I remade my old Hobart CyberTig to be controlled by a microcontroller and it is now capable of doing "high voltage DC" of up to 300 VDC (as well as low voltage high current DC of up to 80 V).
The use of low voltage power supply is stick and TIG, which already works.
My intended use for high voltage power supply is to make a plasma cutter. I have a compressor and air dryer. My problem is that unlike stick and TIG welding, I have never done any plasma cutting, have no friends who do such, and would like to see how it works. (I have read some stuff, but reading is not a substitute for experience)
So, if anyone of you are in Chicagoland, own a plasma cutter and would like to get paid some sensible amount for showing how one works (beer is on me), let me know. thanks
