its scrap from the fabrication shop i work at.

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

[MidgetTodd]

Yea thats the only way I've tried is putting the spool gun on my mig. I dont have a tig and have never used one, just mig and stick.

[rawlins87]

It take alot of heat and time to heat up at first, then less heat and wire.

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.

On tig had to

adjust gas (argon)

switch to dc+ to aniel(sp?) the tungsten on copper

switch to ac

theres on more setting but i forget wtf its called.

Our TIG welder has a "finger control" and I can't hardly weld with it. At my old job, I welded aluminum from time to time, but it rarely looked as good as what you have there!

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

Thanks ..found it...i'd of spent a day thinking it was me.

Some of it looks pretty decent! I want a GTAW welder

I could use an aluminum trailer Gump.

Wish I had a tig welder....My hobart mig can do aluminum but its too much trouble to convert.

hm, me and my brothers just bought a miller mig, and bought a aluminum roll/gun, we havent tried using it yet but i guess i will let all know how it goes.
