Aluminum Welding

I could make you a nozzle that slips over the end of the gun that has a tube on it for argon. Teflon liners are cheap.

how the hell can you weld 2 peices of aluminum together with copper? and no shielding gas? you've got to be kidding... give your head a shake, you might hear some rocks rolling around up there. 
i've used the old copper trick with mig welding steel by clamping a plate of copper to the edge of some steel to prevent the filler material from going over the sharp edge i wanted to keep.
