I have no amperage control via foot or hand controllers. I've even used a known good miller foot control and no dice. Unit works fine when RMT2T Hold is selected but not when RMT STD is selected. I can start an arc with whatever max amp. dialed in but the amperage doesn't deviate from start amperage.

Any ideas out there? Pedal is set up with pins A-E. Do I need one or more of the other pins to use a standard tig torch on this?
