    Please post serial number

    First thing to look at is the brushes--slip rings not dirty, brushes move freely in their holders, not worn out. I think there is a minimum brush length spec in the manual for that machine. Also, if engine RPM is incorrect, it won't weld very well. Get a Kill-A-Watt meter at Home Depot or Harbor Freight and check the freq on the 60 HZ outlet--follow engine RPM adjustment procedure in the manual, and adjust for 62.5 Hz. at the outlet with no load. You can also look for corroded connections in the weld current path.

        Yep, stuff breaks and gremlins get in equipment.

        So it welds OK now?
