The main way TIG differs from other processes is its electrode. The electrode in the torch is a short tungsten rod, sharpened to a point. The difference is that the electrode isn''t consumed. Instead, while working the torch with one hand, the operator feeds a long rod made of filler metal into the weld puddle. This metal rod is consumed by the …
