FAQ
An argon torch switch is a component that is used to control the flow of argon gas to the weld area during TIG welding. It is typically located on the TIG welding torch and allows the welder to turn the gas flow on and off as needed.
Argon gas is used in TIG welding because it is an inert gas that does not react with the metal being welded, which helps to prevent contamination of the weld area. It also helps to shield the weld area from oxygen, which can cause oxidation and other types of weld defects.
There are several types of argon torch switches available for TIG welding, including thumb-operated switches, rocker switches, and foot pedals. The type of switch used depends on the specific welding application and the preferences of the welder.
