Aluminum welding: Spool gun advice?

[69427]

I'm getting more interested in trying out a spool gun for some aluminum welding. Anybody have any experience with these and some advice on what to look for or look out for?

Thanks.

I know this is a million years after the original post, but I have a Miller Spoolmate 100 and I run it on a Miller 211 auto-set. They just blow right through anything thinner than 14 gauge and you're limited to nothing thicker than 3/8". You have to use 100% argon shielding gas, and buy a bunch of extra tips. I had a hell of a time getting it dialed in and went through two packs before I could even lay down a bead.
