Snap On MW120 MIG Welder

Like I said, I thought about that, but it welded great for years with the last liner. I'm going talk with my local welding company tomorrow. It may need a whole new gun. But I'm going to try to file the opening where I cut it first and see what that does.
Burnish it with the wire. Drag it back and forth a baggilion times putting pressure 360 at the openings
