20 gauge? Have you thought about oxy-acetylene welding (or better yet, oxy-hydrogen)? You'll need aluminium flux for the process, but it will probably be easier than TIG welding something that thin. If you want to give it a try, Fornier Enterprises sells a kit with flux and a manual called "How to Gas-Weld Aluminum."
Or just the flux: http://www.fournierenterprises.com/c...roductid=17012
And there might be a new pair of gloves for sale there too
