Hi,
To get parts for your welder you'll need to have the serial number off the tag on the case. This problem could have other causes, have you:
Checked the tension on the wire spool? You ought to be able to pull the wire by hand easily.
Checked the tension setting on the pinch rollers? Too much tension can drag down the motor speed.
You could also have a bad control card depending on which model wire feeder this is.
Regards,
Carl

I have welded countless hours with Linde & Lincoln & even a few Hobarts & the only time that I ever had the same problem was when the ground connection either to the object I was welding, or the welding cable ground wasn't good & clean & tight. Same on stick welders also. I did develop the habit of grinding not only where I was preparing to weld, but where I was placing my ground clamp & that always provided a better "frying bacon" sound as I went along the business of pushing a bead. In a welder, the only other thing than that is involved is the step-up transformer and your wire. Hope this helps.
