proma thc and 60s plasma cutter

Postby ScottLister » Mon Jun 25, 2018 8:19 am

I have a 60s plasma cutter and a proma thc. I removed the jumper to obtain the 1/50th divided voltage but I am getting nothing on my thc. My table manufacturer said to use the raw arc voltage with a 100k resistor to fix the problem. When I read in the everlast manual it says the raw arc voltage is already coming through 2 100k resistors. My question is do I need to install another 100k resistor or can I just connect to the raw arc voltage pins on the cpc connector? Any help would be appreciated.

There is an error in the Everlast documentation. See this thread


I never got this working properly until I joined 2 x 48 volt power supplies together and put 98 volts through the divider board and measured the output with a voltmeter.
