Gas tungsten arc welding (GTAW), also known as tungsten inert gas (TIG) welding, is an arc welding process that uses a non-consumable tungsten electrode to produce the weld. The weld area is protected from atmospheric contamination by a shielding gas (usually an inert gas such as argon), and a filler metal is normally used, though some welds, known as autogenous welds, do not require it. A constant-current welding power supply produces energy which is conducted across the arc through a column of highly ionized gas and metal vapors known as a plasma.

GTAW is most commonly used to weld thin sections of stainless steel and non-ferrous metals such as aluminum, magnesium, and copper alloys. The process grants the operator greater control over the weld than competing procedures such as shielded metal arc welding and gas metal arc welding, allowing for stronger, higher quality welds.

The PowerTig series from Everlast offers a broad range of performance and features at very reasonable prices. Each model's design and control layout is focused on user convenience. The controls are easily identifiable and are grouped according to function. Whether you are welding with AC or using the pulse feature, you can easily identify control settings and parameters with a single glance. The Everlast TIG welders are set apart from the competition because they offer easy to adjust settings without complicated hidden menus and difficult to access features found in many inverter welders. Easy starting and exceptional stability and control of the welding arc are well known features of the entire PowerTig line.

Our lineup of tig welders have high duty cycles that easily exceed the competition. With high volume cooling and IGBT electronics from Infineon, the PowerTig line can easily handle tough jobs. When you turn on an Everlast PowerTig welder, the distinct sound of the fan reassures the ear that it's got plenty of cooling to handle heavy duty commercial applications.

If you are in the market for a GTAW or GTAW-P (TIG) unit, consider the functions and features that each PowerTig model has to offer. From our 200 amp DC only Power I-Tig to our 315 amp AC/DC PowerTig, Everlast has a model with the functions you need in a TIG welder. Everlast Power TIG welders feature pulse welding ability with full parameter adjustments. The AC/DC models feature balance control and frequency control while welding in AC. Panel control while welding is another feature that many users find helpful. Panel controlled welding offers stable and consistent preset welding parameters. For those that prefer foot pedal control, all models offer foot pedal control as a standard feature.
