General Mach Discussion / Help! My "torch on" control is always on. Won't cut current.

« on: May 30, 2014, 06:02:27 PM »

I have a small pro cut plasma table which has been running fine for a while.  Recently the relay of the torch control went bad.  After some fiddling, something happened now there is always current running through the control side of the relay, and it's keeping the relay open all the time... Help please.
