I have yet to manage a weld in aluminium, but it's on my list of stuff to learn. I went to a forum at Oshkosh and watched a guy gas weld the stuff, but he recommended using hydrogen. The Henrob guy is an artist. For most welding, I doubt if the torch is that much superieo but I had mine for over 20 years and I am so used to it, I don't want to change. It is damned heavy though but after constant use you just adapt.
