I'm trying to get a high schools THC operating. the unit is a CandCNC DTHC II
I never see the arc voltage LED light up.
I read that at the twistlock on the plasma rear for THC the pins 5,6 and are typically voltage divided at 50:1
I only see 20-30 milivolts under operation at the audio jack connector into my THC DTHC II. I should expect to see what? I expected a relatively stable dc voltage I can measure with a decent multimeter that is about 3v? I do have continuity through the cable from the twistlock to the audio jack.
I just read the powermax 85 manual page about setting different voltage divider settings, but it seems all settings should be at least 2v
I have not opened the plasma power supply yet. That is the next step.
Thanks.
