I followed Wayne's suggestion and found a way to fully test this welder programmable cycle. I shorted the leads. The program worked. Interestingly, at first, at high amperages, the contactor would drop out intermittently. After I swapped wires so that the contactor is wired on utility power, that stopped and I could ramp output up all the way to 190 amps. DC voltage was obviously very low due to the intentional short condition. So, big thanks goes to Wayne.
