On behalf of Expert Village, I’m Terry and
today I’m going to show you how to use a welder. Alright this is a TIG welder. It runs on reverse
polarity. It’s uses a shielding gas. This particular one is a hundred percent argon.
You have your porcelain cup. You have your tip which is made out of tunstin. And you
have your pedals right here which controls the amount of amps that you’re applying so
you can back off when you need to and apply more amps when you need to. This is the filler
rod. You feed it with one hand and you hold your torch, they call this the torch, with
the other hand. Now there’s different ways. You want to use your hands to stabilize your
torch, so you can hold it like so, a lot of people hold it like this and come off of their
pinky. It’s just whatever is more comfortable to you. So when you start with a TIG you always
want to heat up your metal, your drop in metal. You work it around until you go to, to get
in the consistency you want and then you drop more metal in. And that’s TIG welding.
