Was brazing some parts together last night at about 130 amps DC when the arc got a bit funny. I stopped and restarted things....output with an arc struck and the pedal to the wood is 6 amps....even with with the amps set at 185. Switched it to scratch start with the same results. Pedal position seems not to change anything.
Is it something stupid I can diagnose/fix at home? I've probably only got about 50 hours since I bought it in 2007. I checked my input voltage and I've got 237 volts across both hots with the unit plugged in and running. My Mig, compressor, plasma and other 220V toys work fine....so I don't think it's input power related.
