Forget the mig. The cost of sorting it out to weld ali would be more than the job is worth. You will need different gas, different wire & to change the liner in the torch. It will also take lots of practice to do.
I didn't know I'd have to change the liner - but at the end of the shift - if you have the mig - why not play with it ?
I'd rather play with some plate first though in honesty !
If you had a British motorbike in the sixties you had to have gallons of Hermatite Red and Green.
In the late sixties I had a choice between a new Honda which came with electric start, indicators, etc or a new Triumph which came with a free oil drip tray.

Doesn't that sit with a load of truth Graham ? - my old man's mate gave us a pillion ride on the back of a 305 Honda way back then - Jeezuus - there was nothing british which would do what it did - even tho' it sounded like a tin of nails rattling away !

The steel line (like a net curtain wire) will "pick up" the soft alloy. Even if you have the right teflon liner it will now be full of steel which will affect the weld. Its also better if you have a short torch as you need to keep the feed as straight as possible. You can get adapters that puts the roll on the gun end that gets round some of the issues. But not good for access.
Having to rent a second cylinder might still put you off. Also migging alloy is not that easy or neat.
