This video is not mine. I am using a Lincoln 100. no gas, I know that polarity is correct (I checked). I sometimes get similar pop with all kind of heat ranges and wire speeds. What I know is that I am lazy to clean up the surface. Maybe this is an issue. I remember the worst I got, on popping, was welding the rebars, lot of surface rust.

What wrong with tennis shoes?

Thanks guys.
