This is from a manual for your welder. Would be interesting to see a picture of your manual.
The ground clamp is the one on the right. It is labeled as positive. This is the way the manual said to set it up for wire feed. So is that correct?
I was afraid of that.Can't see your did any thing wrong. Call Lincoln?
The only hassle I had was getting the wire from welder to the tip.
Power Mig 255 here. Buy it once and buy it right.I always remove the tip before running the wire through........ and this thing should work without all this diagnosing........ take it back, you would like a 220 machine better anyway..........Love my Lincoln power mig 200, 12 years old, never a hiccup
I've checked voltage at the outlet. Other things work in the outlet.I have this same welder I can take a picture of my setup. Also did you check to make sure you had a neutral at the outlet?
