No i am not being attacked by russian jets but my MIG welder keeps burning back the wire it never welds to the contact tip. 
It does it when set to the factory specs suggested for the thickness of metal being welded and wire size.

When welding the weld puddle blobs up never really penetrating lots of sparks and crap flying. The wire feeds out and almost immediately melts back until it feeds out and melts back again. My first thought is that the wire speed is too low but wire speed seems to no make a difference.

Ground is good and new bottle of shielding gas I have checked everything I could think of.
