Well i always knew how to MIG and Stick weld, but never tig, i was thinking about getting a machine..

I was wondering what the Different Cup sizes or head sizes were for? and what are the different tungstens for?


How do guys that weld manifolds get the torch into the tight spaces between the runners?

Sorry for dumb questions, im just trying to figure out what im gonna need for the stuff i wanna do ( i wanna start making some headers and stuff like that) but i also wanna make some things out of allumnium
