I have a welder I have been working on for some time am lost as to what is causing this issue. The machine welds but after a few inches the wire stops burning the wire continues to feed and then all of a sudden it will start burning again. I have changed drive rolls, mig guns, new tips. This is on a Miller 74s with dual heads. The power source is a shopmaster 300.IMG_0712.jpg

Welder welds for a minute then balls up.
