When you guys do the "loop and swoop" technique mig welding. do you pull torch so that it angled back at the puddle or push the torch? sometimes I get it to lay nice and flat and stack good, other times it builds up in the center leaves those craters in the center. trying to work on consistancy.
With the auto-set function you can just set it to the wire size you have and the metal thickness you are welding and then it's just a matter of getting the oscillation down. . .whether that is a whip out/whip in, zig-zag, C-whip, J-whip, etc. you can get the stack of dimes with the auto-set without a problem. I've got a Miller Autoset 211 and I can get the stack of dimes using auto-set and an oscillation.
