Some of my first Dozen AL beads with filler rod after the dots and non-filler drills .I dialed down the amperage from 145 to 125a. 65% EN, 120hz. 3/32-4043The foreground coupon is the newest drill .Reason for post: I notice that my filler rod will sometimes develop a small spindly tail. Is this because I am very green and that I am dragging the rod in and out of the puddle?
Reply:Yea if it's not a deliberate fast dab-n-pull it can dribble and leave ugly dross as it oxidizes from only being partially covered by shielding gas.

I did a lot of aluminum railings and a lot of aluminum welding and it was that early one bead at a time thinking that allowed me weld so fast later on. I would not worry about how the overall looks just make sure you can make one nice bead add your filler, lower the heat move a very small amount forward and do it again. Sincerely, William McCormick
