I finally upgraded my little DC Inverter Fusion 200PHF TIG to a decent (for my budget) AC/DC welder, a Parweld XTT202P and began hooking it up yesterday. I've got a foot pedal with it and when I plugged it in, the settings I could alter became extremely limited and controlled completely by the Pedal. So starting amps was 5amps and full pedal deflection would get me to around 200Amps, but with the pedal connected I cannot change them. There is a loop in the foot pedal plug connecting pins 1 & 2 which I think cause this effect but is it "Normal" I have a pedal on the IFL 200PHF and I can set the start amps and peak amps and modulate in between on the pedal, I know the start amps on the XTT202P are set automatically unless you set 4T. I have a Parweld torch with the trigger and amperage control wheel which I am going to connect up omitting the Pin 1 & 2 loop and see what that does. My question is which is the "Normal" way for the Welder / Pedal combination to work?
