so I only played a couple of hours with a MIG and I'm only starting to get welds that don't entirely look like a mutant cross-breed between a roadkill hairy centipede and an alien life form. Plenty of splatter around too. Admittedly, I was just playing with old rusty metal and don't know what I'm doing. But I just saw a series of pics from somebody else with plenty of similar splatter. I mean little spherical beads of molten metal that must be ejected and fall pretty far away from the weld, and end up like little beads all over the place. I guess those could be ground down easily enough, but probably better to not have them in the first place. So that got me to be curious about it. What's causing these? and how to avoid them?
