Hi,I have a miller syncrowave 250 that is almost 2years old. I tried to run on ac for the first time to do a small aluminum repair today. I ran about 20 seconds at about 80amps stopped to take a look and reposition the piece and it would not initiate the arc. All I could get is a little spark each time I touched the tungsten on the workpiece.I have checked points and torch connections. Also the ground. DC IS OK. Maybe hf problem? Any suggestions.
