Tagging Matt Hayden as we'd communicated earlier on dual shield questions. Wasn't happy with the performance of the Lincoln 71M dual shield wire I tried. No matter what I did, there was random worm tracks, lousy root fusion in 1F, and man it was smoky. Decided to try another flavor and wow what a difference. This is Eutectic DO266S set at 25V/250 IPM 40 CFH 75/25 gas. The first thing I noticed was a fraction of the smoke, and no worm tracks. Wet in really nice. And even in 1F there's root fusion. Very promising. Still need to get used to it. Definitely need to slow down for more fill, and shift my aim up a little, as I'm favoring too low in the fillet. This may end up my go to dual shield. It's a little spendy at about $8.79/pound, but it works.
