I have been stick and MIG welding steel for years but I bought a spool of .030 aluminum wire and threaded in my mig and it feeds fine. I've never welded aluminum before, how important is gas for this ? will it work without gas ?
I tried it without any gas (no argon on hand) and had terrible results but I don't know if it's settings although I tried all of them or if it's b/c no gas.
Trying to weld 1/8" aluminum to start with.
