 I want to repair a broken aluminum cast pickup tube from an automotive
oil pump. I have a cheapie MIG unit running .030 flux wire for
steel. I don't have a bottle or regulator. This is not a high-
strength application. What result will I get with .030 aluminum wire
and no gas?

It won't be good. Take it to a welding shop.

I'm beginning to think there are no easy cheap ways to do repairs on
aluminum. I've tried two different torch weld alloys and gotten mixed
results at best. The biggest problem I've found with those though is the
expansion and contraction of hte metal. I can do very small repairs, but
for anything bigger it breaks itself, or melts the weld further back as you
try to work along further up.

You just have to invest in the right equipment I guess.
