In TIG Welding (Tungsten Inert Gas Welding or GTAW), the Tig Welder strikes an arc between a tungsten Tig welding electrode and the workpiece.
A separate Tig welding filler wire can be added to the weld pool as necessary.
The weld pool is protected from oxidisation by pouring an inert welding gas (usually Argon) over the weld pool; this welding gas is usually turned on and off by the Tig Welder.
Tig welding is fairly easy to learn (especially if you have experience of Gas Welding as the skill set is similar).
The up side is that Tig Welding is probably the most versatile of the arc welding processes
The down side is that it is a slow process and a good quality Tig Welder can be expensive, although prices have been falling as Tig Welding has become more popular.
Tig Welders fall into two basic categories:
DC only Output Welding Current Tig Welders - which can be used for most applications including the Tig Welding of Steel, Stainless Steel and Copper.
AC/DC Output Welding Current Tig Welders - These can be used in DC mode for Tig Welding of Steel, Stainless Steel and Copper etc (as DC only machines), or in AC mode, where they can be used for Tig Welding Aluminium and Aluminium Alloys. AC/DC Tig Welders are however, significantly more expensive than DC only Tig Welders.View our Tig Welder Range
