Hi George,

I don't know the answer to the above question, but when I MIG welded many years ago I seem to remember a spray to reduce splatter - maybe it's that?

Anyway, I wanted to also suggest that if you weld outside (to stop the garage catching fire for example!), and are using a gas MIG, watch out for the wind blowing the shroud away. It makes the weld splatter, and gives a visually, and probably mechanically, worse weld. Even a light breeze is enough to do it. A non-flammable shield might help, or wait until there is no wind.
