A Quick Question on TIG Welding

Yes and no.
You can get different grades of filler rods, ask for ones that are ''fully killed'' steel filler rods. They will have a light copper coating on them.
That is to say that they have very few imperfections in the steel.
If you use something like a coat hanger for instance, the weld will pop and bang because of pockets of imperfections in the wire.
Ask any competent welding supply shop for tig filler rods and they will set you up with the right ones you need as well as the tungsten rods you need.
