[QUOTE="patooyee, post: 391893, member: 483"] The above pic is the first beads I've laid so far on aluminum. Machine set at 180 amps, 1/8 thoriated, unknown base aluminum, 5356 filler rod. I know why the end of the weld is falling though ... it is because the heats builds up there and has nowhere to go. I've read to add more filler to prevent that but it seems I can't add it fast enough? My tungsten isn't balling, but it doesn't seem to be hurting anything. Instead it is forming little nodules on the tip. Weird thing, my machine came with two tubes of 5356 filler rods, one seems a bit older than the other. The older tube ABSOLUTELY won't weld, contaminates the ever living **** out of everything whereas the slightly newer tube seems to be doing fine. Any theories on this? Should I trash the older tube? Input? [/QUOTE]
