Too bad I don't have a digital, hopefully I can 'xplain myself. Yesterday when I was praticing, I was notching a pice of tubing and welding it to another piece. I'm using .25 wire right now. I had one bead that rocked, looked almost professional. Anyway, during this bead, I found myself instead of just moving the nozzle straight, I was moving it back and forth left to right (actually it was up and down, but for simplicity terms). My bead looked great. Is the movement of the nozzle as described right for something like I was doing? Should I move up to .30 wire? Reason I was doing this is because of the notch itself. I was using the chop saw method, so instead of the "U" part being straight, it was angled and I felt the bead wasn't wide enough.
