Question for you guys that run a lot of dual shield. Do you think that "slag you drag" is a hard rule? I was padding beads of .045" Lincoln 71M Outershield( C25 gas ) at on plate today set to 25V/250 IPM. Dragged the beads left to right, and pushed the beads right to left. Darned if I could tell the difference. Just used a very slight ( 5-10 deg ) tilt either to or away from the direction of travel, with the gun pointed straight in. I haven't tried a cut & etch yet to see if there's any difference inside, but on the surface it runs great either way. Love the spatter free welds. I must admit I was wearing Crocs and never so much as felt a spark in an hours welding! I know, I know, it's not proper footwear. My shop, my feet, my rules! :)
