I've had a MIG welder for many years and have gotten pretty good welding
sheet metal with it. 
( The greatest improvement came a couple of years ago when I replaced my
Harbor Freight unit with a Hobart 140)  
Anyway, my current project car is Aluminum and I have several cracks and
patches that need to be welded. Is it worth buying a Argon tank so I can
weld the cracks my self or is there a whole new learning curve when welding
aluminum with a MIG?
