I;ll give everlast a buzz in the morning to get the polarity on the pins.
Thank You
Here is an older drawing that has the polarity labeled, but since you may damage things, I would invest in a volt meter just to be sure. Also be aware that there are current limiting inline resisters on those pins so the voltage reading on your THC might be different from the settings that worked good for your Hypertherm.
Long arc, short arc, heliarc and in-the-dark!
