Mma Welder

What type of TIG welder do I need for aluminium?

I’m looking at getting a TIG welder, for aluminium. I’m a competant mig/mma/Gas Welder, but I’m a bit confused by all the TIG machines offered. Some say they won’t weld aluminium. What type/size machine should I be looking for on a limited budget?
This is needed for thin aluminium, I have an ally reel for the mig, but is only good for thicker ally.

Hi You need a TIG welder with AC. The cheaper DC tig welders are for steel and Stainless Steel. Alloy requires an Alternating Current (AC) to break up the formation of oxides and provide a clean weld. AC/DC welders, they are switchable, can be 2 or 3 times more expensivethabn straight DC. Unless you are going to do a lot of welding it will be cheaper to take to a good fabrication shop. Remember you will need Argon as the shield gas.

Hope this helps.

Cheers Dave
