I wonder if you can help me out, I have a thermal arc arcmaster 300 acdc Tig that is acting up if I use a foot pedal with it. Foot pedal disconnected, I can adjust power on front of machine and weld all day long using the torch switch. If I plug pedal in and select remote, I press the pedal and arc fires and shows 6 amp on readout. If I continue to press pedal to increase power, the readout will goto 0 and no power increase. Pedal is a brand new ssc pedal which ssc stated is correct for my machine
