I hope somebody can help me out here. Iím trying to weld up some cracks and holes in old body panels. The metal (22ga) is very good but all I seem to do is burn through when I try to weld it.
Iím using my MM 250 with .023 wire with 25/75 gas mix set at 25 psi. My gun is a Bernard T3 that I just put a new .023 liner in. The suggested settings are 16.5 volts and wire speed at 38 (low). Iíve tried settings all over the board with no success. Canít experiment too much as I donít need any more holes than I already have to deal with.
Thanks so much,
