Adding a spool gun to my current welder?

[JMcDonald]

I currently own a Chicago Electric "Dual Mig 151" welder. I bought an OxyAcetylene Setup mainly so Id be able to weld Aluminum, but I am concerned about my success in Al with this setup (not only the ability to lay down a decent bead, but the effects of the heat input into the Al, and the structural integrity of the weld).

Question: Is there a way to convert my MIG to use a spoolgun or anything like that?


If not, and I dont get the O/A to work with Al like Id hoped, then Ill just save up a bit more and either get a new Spool Gunned MIG or a TIG.

I started learning MIG welding with the same machine you have.

It will feed aluminum -- I've run plenty of 4043 aluminum wire through it -- no real problems. The liner is some sort of plastic or vinyl that is OK for Al.

Make sure your tip is one size larger than the wire.

Hmm...

Is Argon the universal gas for welding Al (with MIG, TIG, etc)? If so, then maybe Ill just buy an argon tank and try it out!

Argon is the shielding gas to use for mig Al. flow rate of 15-25 C.F.H.

Nevermind.
