Topic: Welding Help, welding thin metal to thick metal
I've got a Millermatic 141 (MIG with gas) and have low double-digit hours using it. I can weld thin metal to other thin metal, I just have to keep the power down and be smooth. Thick metal to other thick metal is easy, but thin metal to thick metal is giving me a hard time.
I end up keeping the power low to keep from burning holes in the thin metal, and laying down a few beads on the thin metal until I've got some mass of metal built up so I can turn up the power and weld the built-up bead to the thick metal. This appears to work, but looks nothing like what good welders do when they weld thick to thin. I was thinking that I could turn up the power and re-flow the whole thing, but is that necessary or even a good idea?
What am I missing here (other than skill, knowledge, talent, etc)?
