Welding Aluminum

I have a small Hobart Mig welder and would like to weld some aluminum. Can someone tell me what I will need to convert the welder? Is it just a matter of changing wire or do I need a different type of gas?
Thanks,

Argon gas, different rollers, I think the same tip will work but depending on how old your whip is you may need a new liner as well.
Aluminum doesn't like to be pushed down the liner like steel wire, you need to make it as easy as possible.

You probably need a lot more amps than what you have to weld aluminum of any thickness..You may be able to weld some thin stuff..

another thing to consider is that aluminum wire is very soft and does not feed well in a small mig..One really needs a spool gun to mig aluminum..

Another thing to look at is what alloy that you have..Some alloys of aluminum are made to be welded and weld very well..some others are not..

what those guys said. and. if you have a 130/140 machine, you can weld thin aluminum. i have done it. but tell me tell ya, its NOT easy. even IF you can get the wire to feed perfect.

Another little trick you can use to help the wire to feed is to keep your welding lead as straight as possible so the wire will not have to be forced around any bends.

Thanks for the help! We used epoxy instead of welding. I'm going to try it one of these days.

Actually, welding aluminum is fun. I have never done it with the long mig lead though. We had spool guns at the shop I worked in.

We also had a welding hood that you wore a respirator under. Breathing the fumes can make you pretty sick.

I also wore that when welding galvanized metal. YUCK!

I never had an issue with stainless, hastelloy, or inconel.

It would be interesting to try it with my little lincoln mig someday.
