30cab,

All good info, for the shell tack the edge first, then depending on the length of the crack
put more tacks, use 15-25 amps. Weld no more than 1/4 long, and if you get crap on the back side you are too hot. Take home " junk " from work for practice. Will your
machine weld AC, if so, practice on soda cans. Start off with .040 tungsten on light stuff. I weld .020-.025 SS and it's tough.
