Hi, I'm new to welding, I just finished setting up my used MM175. I plugged the machine in and turned it on just to see if the feed rollers would turn. After pushing the switch to turn the machine on it remained dead. I checked the voltage at the outlet and that is correct across the 2 hot lines, there is power to the reset on both legs. I have no lights on the circuit board (green & red) if anyone has any idea what could be wrong I'd appreciate hearing from you, thankyou.
