Sounds like everyone has had the same experience. I think flux core is
fine when it's sunday and you're out of gas. It works fine but it's
messier. It's also harder to get it to feed cleanly--perhaps because the
roller crushes it a little. It's almost as bad as soft aluminum wire.
I use straight argon--I don't remember why, I think it's because I do a
little aluminum welding as well, though every time I go through all the
setup I wonder why. You have to replace the entire feed system with a
lined tube. I borrowed a gun that feeds from the gun handle instead of the
base unit, and that was really slick. If you want to try MIG welding
aluminum, that's the one to get.

For all my work, including body panels, I use the Argon - Co2 gas bottle
and
0.023" diameter MIG mild steel wire which is copper coated to keep it
from
getting rusty when I'm not using it. It works great. I bought it 15
years
ago for my restorationand have been using it for the one I'm doing now.
It
has 3 settings. I use the lowest setting to do butt welding (edge to
edge
for smoothe results) as setting 2 for overlap joints where no one will
be
able to see them. For thicker pieces, I use the #3 (High) setting.
