Hope this is in the right place to post. If I am out of line, please advise. I have a CPM 1125ESAB plasma with a pt-27 torch. Is there any way one could run a cheap chinese pt-31 torch on this unit? I do a lot of light cutting and would like to utilize the cheap torch to reduce costs. But I am unsure how to wire the esab as it has an extra wire running into the torch. Might this be an arc start circuit or one to maintain arc? And could that circuit be made to run externally on the side of the torch (w extra insulation)? Or would this be a mistake waiting to happen? Any and all ideas and help would be appreciated.
Thank you,
Don
There are circuit schematics available :
