Not possible.
Aluminum is very tough to weld. Because it conducts heat so well it just burns through in a giant blob. There is no color change or indication of when it is hot and about to melt. It just suddenly melts and usually burns through.
For a MIG setup:
Aluminum wire is too soft for any welder to push through a line.
You need a special powered spool gun at the end and different gas.
Even then results will be very substandard without a ton of experience.
Practice make perfect, so get a bunch of scrap and practice.
