| TIG welders are designed for the Gas Tungsten Arc Welding process (GTAW), which is commonly referred to as the Tungsten Inert Gas process (TIG welding). The TIG process derives the heat for welding from an electric arc established between a non-consumable tungsten electrode and the part to be welded. Filler metal, if used, is manually feed into the weld puddle when TIG welding.
The TIG welding process requires an air- or water-cooled torch to hold the tungsten electrode and is connected to the TIG welder. The TIG welding process also requires an external shielding gas, typically argon, helium, or a mixture of the two to protect the molten metal and electrode from atmospheric contamination.
High quality welds can be produced with TIG welders. The TIG welding process also has all position welding capability and is excellent on very thin materials. Additionally, a TIG welder makes welds that have outstanding appearance and clean-up is fast and easy since there is no slag and essentially no spatter.
