– not going so well. experienced welder, using recommended setting on machine. green tungsten, clearance effect set to 0-minus 3 (tried all settings), AC setting, proper rod, meticulously cleaned aluminum. 100% argon. 15cfm.
base metal wont puddle (3003 AL) . certainly wont flow. filler rod beads up (4043).
Im going to go get another alloy sheet, but this has been disappointing to say the least. this will have been an expensive mistake if this machine will not weld aluminum.
