I have a 200 DX I believe it is the model that was around just before the digitals came around. Well anyways I recently fired it up and the foot pedal doesnt seem to be working. Its just acting like a switch basically with no amperage control. The work piece is grounded I know because I can strike an arc without the pedal hooked up(amperage control on the machine works when not using the pedal.) I've fiddled with amps on the machine, and the pedal control knob. Ive also tried turning all the other various knobs from 0 to full(AC Freq, and bal.) Also If I turn the pulse on the machine will weld to whatever I set the high, low, and frequency to(but the foot pedal still wont have control; just acts like a switch like say on the torch that came with the machine.)
Ive tried it with both the stock torch and a CK torch.
I looked around a bit and couldnt find any threads with issues like this.
Any ideas? Thank you
