PP256 Plasma stopped working

[performance]

For starters you are using 4T. Put it in 2T. It won't cut if it is in 4T, if you keep the trigger held down. Not sure why it went into duty cycle unless you were keeping the pilot arc on for extended time. You are under pressure though on your cutting psi, which should be about 70 for CUTTING, and probably higher if static. What size compressor are you using? (cfm/ tank size). Is your torch in the negative?

I tried it in both 2T and 4T. No luck. I bumped the air pressure to 70+lbs at the welder, and 90 at the compressor. The compressor has a 15 gallon tank, and is rated at 4.9cfm at 40 psi, 4.5 at 90.

I don't think the compressor is the issue. I had made many cuts with the same setup without any problem. I had just made a cut before it stopped working.

The torch is connected to the negative connector.

Thanks for your help,
