Hello,
I have a MM210, serial# LC054331, with factory installed spool gun.
I am original and only owner, MM is always indoors.
Honestly SG was used for one project that was a few hours of Non-continous welding.
The steel side works perfectly.
The spool gun has the 35volts at pins #1 and #2
Has same voltage from circuit breaker as steel side that feeds both.
I was able to use a known working spool gun that yielded same result.
Original spool gun plugged into steel side activates steel components.
Miller said replace the 1 and only board in machine pt# 204807
I am guessing now problem leads me to the RC6 plug on board pin#4
