1 - Check the ground connection to the work, including the actual cable to clamp connection.
2 - Make sure that the wire feed rollers are nice and clean. The wire needs to be clean too.
3 - Check that the polarity changing wire connections are nice and tight, clean, etc.
4 - change and or service the contact tip at the end of the gun.
as always, gently clean out the loose junk inside the case. A clean welder is a happy welder. :-)
