Welded aluminum for the first time...

Its tough going from steel to alum. Have to move much faster, adj to the differences of the spool gun, dont have the easy signs of heat transfer to go by. I've tried several times and have to admit I'm not good at all with alum.

Ive heard its possible to weld with mig, but very uncommon

Don't you just switch gas on the mig and polarity maybe. I gotta Hobart 220v and all the wire just never needed to weld anything aluminum yet.

Have to use a spool gun. Alum wire is not rigid enough to be pushed through the typical 10' lead on a mig.
