I have this plasma torch:I am pretty convinced that it is a knockoff of Hypertherm PAC-130 torch, see So, I want to slowly make a plasma cutter. My first test/experiment could be as follows: 1) connect torch and pilot leads to power supply, electrode negative
2) Set power supply to 250 volts and 20 amps max.3) Start compressed air flowing.
4) Turn on power supply5) Nothing should be happening
6) Give it a little jolt of high frequency, the shorter the better7) That should ignite the pilot arc
8) Blue flame should be coming out of the nozzle. That is the pilot arc. Watch arc for a while.
Does this sound like a sensible first step? I am aware that it would not produce the main cutting arc, but it could make a pilot arc. thanksi
