We just got our new miller 252? or something like that in our shop, Im new to mig, its been all tig and gas welding for me til now: I was having popping problems, watched the vid, set it all up and still had the problem, ended up being the tension on the wire feed, it looked fine but when you go to weld the slight pressure of the wire going into the work paused, or slipped a bit so the wire was stopping and starting, increased the tension and works perfect!
