You need AC and hi frequency start to weld aluminum with a tig.
Yes you can weld that .032 metal

You can also weld it with an oxy acetylene rig and very small tips, or oxy Hydrogen (though I haven't tried the latter)

If you want to learn that, go over to metalmeet.com and see if you can get to a metalmeet near you.
There may be somebody willing to share some hands on help.
