My other issue with this machine is that on line voltage (230-240) it is so inconsistent. Will weld fine for a short time and then suddenly act like someone cranked up the wire speed and start banging the weld with wire or, just the opposite and burning the wire up to the tip. Again no help from Miller or my LWS. I am absolutely tired of jacking with this. I have been a dedicated Miller user for more than thirty years but now am seriously considering going red.
