No.
Are you sure it is a high frequency one ?

Yes, granted you have a decent PC regarding latency and set it to /64.
Beware that most cheap BOB's use very slow optocouplers so it might end up not working for you even when set at /128.

Disclaimer:
Mesa clearly states not to use the THCAD300 with high frequency start plasma sources.

That being said, i have several of them (5 or 6, not sure) in daily use with high frequency and high voltage start plasma sources.

So if you think you can follow instructions on how to wire it and know your way around high power electronics and stuff, post some pictures of the insides of the plasma cutter so i can try to figure out where the THCAD should be connected.
Be warned that things will go up in smoke if any mistake is made and i will refrain from giving such information as soon as i deem it unsafe. That is my decision to make, not you, not this forum or anyone else, after all it is highly dangerous, so chances for fire, smoke, injury or death are also high.
