Welder Tig Welder, Welding Tig Welding. The Tig Welding process allows the Welder exact control over the weld pool which results in a clean weld with deep penetration. TIG Welding Machines are frequently used to weld stainless steel, aluminum, magnesium, copper, brass, chrome and other alloys.

The acronym TIG stands for tungsten inert gas; though, the official name for the progression is GTAW, Gas Tungsten Arc Welding. A type of arc welding, TIG uses a tungsten electrode held in a TIG torch. Shielding gas flows from around the tip of the torch to stop weld contamination. The tungsten electrode is not consumed by the weld; it simply serves as a means of directing the arc. A separate filler rod adds metal to the weld. The welder uses one hand to hold the TIG torch, one hand to hold the filler rod and a foot control to operate the heat input to the weld.

Most stick Welding Machines can be converted into TIG machines through the addition of an air cooled TIG torch with a gas valve on the neck, TIG machines also provide additional features that allow for wider welding applications. High frequency start features produce an arc without a physical strike. Preflow and post flow, a characteristic that starts the stream of shielding gas before and extends it after the actual welding. Particular frequency settings manage the welding arc for welding different types of metal, including aluminum.

Operated By Only Whoever Is Skilled Welder

A Tig Welder can weld any type of metal. Specialized Welders are required for TIG processes because the skill required is high. TIG welds are of the highest quality when compared to stick Welders. Stick Welders can weld steel where medium skill is required. Stick welding is used for rugged outside conditions and repair shops. Tig Welders are used in more refined conditions and applications.

TIG welders require less current and offer a pleasing weld appearance although looks and weld integrity are not related, a pretty weld can also be a useless weld. A tungsten electrode is used to carry the arc from the torch to the work piece. Filler metals require separate electrode that is fed manually. The gas is used for shielding.

Most of the welding packages have a work cable, clamp, input power cord, TIG torch, gas regulator with hose and foot control. Shielding gas is also required but it is sold independently and the bottles containing gas are usually for hire. For safety reasons, individual protective gear, especially gloves, Automatic Welding Helmets and protective clothing should be worn to shield the welder from het, infra red, ultra violet hazzards.
