I'm no welder, but it's nice to know that I'm not the only guy who is occasionally tempted to throw a POS tool across the room. Just the other day, I had my GP Triton charger in my hand. I was mad, and I was looking real hard at that concrete wall in the basement. I didn't do it, but I was sooooooo close to chucking that thing.

I've done some mig welding on mild steel. I do okay with it. I've been tempted to buy a Tig machine several times, but the ones I wanted always cost close to $1000, and I don't think I can sell enough mufflers to ever pay for it.

I used to be a Journeyman sheet metal worker. I had to weld galvanized sheet metal more times than I'd care to admit. Nasty stuff. You need enough ventilation to simulate a tornado, just to keep from passing out from the fumes. I would always drink milk before, during, and after welding on that stuff. It helps keep the headache to a dull roar. If you don't drink milk, the headache is enough to make you contemplate a swan dive off the top of a very tall building with a paper parachute.
