I just wanted to let you all know I am open to any suggestions you have for a newby on tig. I seam to be able to join metal together alright, but still a whole lot of grinding and cleaning. Still learning how to manipulate that puddle. Also noticed that puddle stops puddling somtimes and gets this black bubbly looking. This is all on 304 stainless. I just grind it away when I get that. Seams to be metal under it all.
