Could I use the inverter from a MIG welder to make a plasma cutter? Answered

I would buy a plasma torch, connect it to a compressor, and then connect the output of the MIG welder's inverter to the torch. (I'll sort out a HV system to strike the arc.) My basic question is: 'Could this work?'


No, you can't. The voltages and amperages are very diferent between a plasma cutter and a mig welder. i.e. a plasma cuter has 50 AMP and min 200 Volts. but the MIG welder has 50 VOLTS and 300 AMPS.
