I know you can get aluminum weld wire for migs and that you would have to use 100% argon.
What I need to do is make some modifications to my oil pan. I want to delete my current oil drain and install a new aluminum oil drain bung.
Any tips for me? Anything I should know? Should I just pay someone?

Aluminum MIG with a spool gun is more for production work and welding plate or long runs. Not for something detailed like welding a bung in, because you would have to more so fast it would land up looking like shit. Not to mention you need at least a machine equivalent to a Millermatic 215 and a spool gun which are around $550. Just have it TIG’ed by someone
