TIG Welding Torches

TIG stands for tungsten inert gas and is technically called gas tungsten arc welding (GTAW). The process uses a non-consumable tungsten electrode that delivers the current to the welding arc. An inert gas, typically argon, protects and cools the tungsten and weld puddle.0Image result for Welding Torches defineOne can distinguish between two types of welding torches: injector torches for low pressure acetylene and medium pressure torches for high pressure acetylene.An arc welding torch is a device that is used to transfer current to a fixed welding electrode. The torch also serves to position the electrode and direct the flow of shielding gasImage result for Welding Torches defineThe torch is the tool that the welder holds and manipulates to make the weld. It has a connection and valve for the fuel gas and a connection and valve for the oxygen, a handle for the welder to grasp, and a mixing chamber (set at an angle) where the fuel gas and oxygen mix, with a tip where the flame forms.
