I have to weld thin wall duct work sometimes at work, and even after cleaning the galvanization off, it is still "dirty" so to speak. I have found using .030 cored (no shielding gas) works well. I have the ability to use either Pulse or Mig Mode and choose the latter.
I tried a few other things that did not work so well. Using a variety of shielding gasses only produced more spatter, and pulse welding in several configurations made the arc rather unsteady. I did try several pulse configurations to get the background arc to hold, but ultimately had better luck in MIG Mode.Comment

Have you tried using unobtanium? Or try magic....either should work.Comment
