I've been welding in this car for a year and never had anything like this happen.
I ran out of gas and the welder was doing fine. Got a new bottle delivered today and hooked it up. When I started welding it sounded different, lots of soot, the metal doesn't puddle the way it did before and the welds look like crap! (IMG:style_emoticons/default/headbang.gif) The other thing that happens is that the wire fuses itself to the gun tip. Settings are the same on the machine and everything was fine. The only thing that changed was a new bottle of gas. I'm sure it's possible for them to put the wrong mix or the wrong gas but before I call them is there something else I should be looking at?

Still curious if OP's problem went away.
@Jeff Hail Jeff, any advice on TIG'ing Galvanneal? I've tried grinding it back (both sides) but some of the zinc is actually annealed into the steel and can't be removed by grinding and still leads to electrode contamination and puddle pops. Not an issue for MIG. At this point it's painfully slow with TIG but I'm surviving. However, the thought of going back to a MIG rig has crossed my mind several times now. Best success I've had is by feeding as much filler as quickly as I can. I suspect it helps dilute the zinc in the puddle by getting fresh filler (ER70-S2) in there. Apologize for thread high jack. I'll post fresh thread if I've offended anyone but this appears to have the attention of the welders among us. |
