Yahoo!!! Something I know about!
MIG is easy, bt yes you *must* use Argon, not the more common and cheaper 
Argosheild, it just don't work, and use Ali wire (which you probably guessd)

I would personally use TIG, it does a much much neater job, and as long as 
you use the same grade filler as the parent material it's a piece of 
cake.  Just make sure that the welding equipment is setup for Ali, on ours 
you need to set reverse polarity, and crank the starting (or 
striking...depends on the manufacturer) voltage a heap.  Apart from that 
it's TIG101 stuff, clean surfaces, clamped tightly and away you go :)

Remember, Arc and MIG are for pigs, TIG is for Artists ;-)
