Welding Aluminium With A Mig

[zebra]

Hi

I have a mig,is it possible to weld alum?

If not what da ya suggest without purchasing a tig.

Thanks

I could be wrong...and quite often am, but it seems like a subtle ad

hmmm seems i was right...

...while im here the el cheapo gasless migs you can get from repco, supershite auto etc......im guessing it wouldnt be possible to weld aluminium with those...all this talk of gas has me a wee bit confused lol

you can get the alloy wire for those small units - and no doubt there are those disposable gas canisters in Argon also - but then you need a new liner for the wire feed ....

prob easier to buy one of those cheap AC TIG machines if you are going to try it.

cheers thanks chris

which do you think would be easier mig or tig...im a total newb at welding...was thinking of getting a mig cause i fail at arc welding somthing bad...but havent really had much practice in general

Tig takes the longest to learn for sure, but it will give you a buzz when you lay your first perfect bead.

I dont stick weld very well at all, I have to guess what the filler is doing due to the slag hiding the weld.

I bought one of the chinese 200amp AC/DC tigs, similar to the ones on ebay. There is even one with a plasma cutter built in. Does the job nicely and easy enough to learn, just hit the Miller US website and practice, then practice some more. The gas can be expensive though.

My opinion is that mig is faster for batch work and tig is higher quality for custom work.

Bah, MMAW is easy, you just need to know where to look while welding. I watch the weld puddle at the end of the electrode, if you have the correct current settings for the material and electrode and maintain a nice short arc length. The rest takes care of itself!
