you can actually mig aluminum too....I've done it a many of times on live all trailers and trailer doors...good penetration is a must, and you have got to know what your doing, and have the right gas mix which you can find on the internet....

twfields79 "Are you sure heliarc welding will work on cast aluminum?"

I had the entire cast aluminum transmission/engine case heliarc welded on my old BSA after I broke it (please, don't ask how, it's embarassing) and never had any more problems with it. I suggest you do a little web surfing on the subject to get a fuller picture, but here's one site with a description:
