Can anyone please give me some suggestions as I am new at this. I tried running a few beads on some 1/8 6061. I cleaned the plate with a scotch bright hand pad, then wiped it clean. I'm using 3/32 Ceriated (sharp point), CFH@13, 3/32 4043 filler. NO.6 cup (no gas lens). I'm curious why the bead was coming out so wide? they're anywere from 1/4 to almost 3/8" wide. They are also very dirty, I could see black stuff floating in as I dipped the filler (not sure if this was coming from the parent material or filler), and they even feel rough or gritty. I tried the the balance at 20 and then 10 for max penetration, 125 - 150 A, and tried 100 to 125 hz. I noticed as I pull the electrode away from the part, the arc widens, how close should the electrode be held to the part? Any help would be great.
