Loosen the drive wheel, remove contact tip and cut
wire off so 1/4'' sticks out the rear of the tip. Go to
your grinding wheel and grind about 1/16" off the
front of the tip where the wire is welded to the front
of the tip. Now tap the end of the wire at the back
of the tip and it will break loose. Run a gas welding
tip cleaner in the front of the tip to take the burrs out.
Works every time. G.M.
