Kevin-
Thanks for the response. It's good to hear that all this will probably
fall into place at some point.
I'm surprised at the difference I'm seeing between gas and gasless. I
could do fairly reasonable beads with self-shielded wire but as soon as
I set it up for gas, I started just dropping beads and globs of weld on
the surface of the 20 ga. steel and have a hard time getting a good
bead. Sometimes I actually end up making little arches of weld--like
little handles.
I'll keep experimenting.
Thanks again for the tips.
