The HF start is not shutting off requiring "scratch tig" to weld SS or CS. I was directed to the foot pedal, an RFC-14, and found it in very good condition with the exeption of a green (typically ground) wire not connected to anything. There are stabs on the coil and on the cen limit switch within the footpedal, however neither stab is grounded. It is a 5 pin receptacle however my manual shows a 6 pin receptacle.
