So wanting to expand my capabilities I would like to learn to weld aluminum. I have a Millermatic 211 MVP welder already which does everything I need to do as far as steel goes.

If I was to take on a project which incorporated aluminum I have no way to weld it and really cant afford a TIG set-up. So my question is a spool gun capable of welding sheet aluminum (miller says 14ga or larger), or is it like the flux core of aluminum welding and designed for odd jobs that are hard to reach? Do I need a TIG to do it right?

Also is there any difference in welding Aluminum or steel(technique)? Miller suggests "pushing".

I don't plan on doing any structural building with Aluminum, so I dont see me going thicker than 14ga.

I'm continuing my research it has only begun. I know there is some knowledge on this site, figured I would tap into it again.
