Question about Lincoln Welding Tools
Sound like you have the wrong polarity for the wire you are using. Without knowing what kind of wire you are using, check the following:
A) If using inner shield wire (gasless wire) your ground clamp must be connected to the positive (+) side and your ground cable to negative.
B) If using metal core wire (need gas) ground clamp must be on negative side.
Polarity change it's done on the upper side of the drive rolls.
