Snap On MW120 MIG Welder

Just throwing spitballs here but are you sure enough amperage is getting to the machine? If using an extention cord or plug that that may not be caring enough current. Since you have the feeding problem solved maybe try connecting to a different power source or outlet
Ok will do. I am helping Kitty with some honey dos right this minute so it'll be a little while, but I can tall you it has infinite adjustable wire speed and heat controls which I like. It also has a selector for spot, continuous and stick welding and one more knob....I forget. But I'll get a picture of it in a bit. I thank you graciously for trying to help.
