75/25 currently.

I was in Home Depot, and I happen to see they carried alum wire for this thing...4043 if I'm not mistaken.

It didn't have any info on the gas usuage, or anything, but I was curious if it is possible to mig alum?

Basically i/c pipe and what not.

Any input would be greatly appreciated.

Thanks

 

Don't you need a spool gun for MIG to weld alum?

Hope that help.

 

Theoretically you should use a spool gun or a push pull set up, but it isnt a requirement, to use a normal gun you need a different type contact tip suited for aluminium and use a teflon liner and wire feed wheels suited for aluminium and run 100% Argon or a Argon/Helium mix.

 

and keep your gun and lead very strait if you use a regular gun.otherwise you will have one big mess.

 

birds nest comin.

if a welder is cheap, chances are its a piece of **** and u wont be happy with the results.

 

oh yea forgot to mention keep it as straight as possible and also if you can get a shorter gun get it, and just be careful how you set the tension on the wire feed roller as it does bird nest very easy

 

It was approx $400-500 bucks.

It mig's very well imo. I've had ZERO problems with it, thats why I ask.

So it's possible to do small jobs with alum, it's just the welder may have issue feeding the wire?

I'll look into the accessories and see what I can come up with.

Thanks.

 

i have heard of people using what you have to do some small jobs.just get a bottle of 100% argon and some of that wire you seen there in the store and try it out.i have used my dads spool gun setup on his miller and it is a very messy looking weld though.

 

remember to use a teflon liner and the right contact tips
