Hi, I just bought an used plasma cutter few days ago. I removed the cover and took a few photos of the internal. Can someone help me to identify whether this is a HF starting unit or a pilot arc starting unit. I think it has a P80 torch. unns_boy Gallery - My Photo Gallery

It would be easier to identify if you showed pictures and details of the brand name and model number. The Torch appears to be a Trafimet P80......which some plasma manufacturers call a "High Voltage" start torch. It can use a capacitive discharge, an inductive discharge or high frequency starting method, all of which can create RF electrical noise interference. There is some circuitry in the pictures that appears to have components as used in a high frequency spark gap oscilator circuit.

I am 99% sure it is a high frequency start system.
