598478 - ESAB HW-26V Air-Cooled TIG Torch Body with Gas Valve

Reliable Replacement TIG Torch Body

The ESAB HW-26V TIG Torch Body (598478) is a premium replacement component designed to restore the performance of your air-cooled TIG welding setup. Built to the rigorous standards of the classic Heliarc line, this torch body is engineered for durability and consistent electrical conductivity. It is specifically designed for the 26-series style torches, which are among the most popular and widely used heavy-duty air-cooled torches in the industry.

One of the standout features of the HW-26V is the integrated gas control valve. This manual valve allows the welder to open and close the shielding gas flow directly at the torch handle. This is an essential feature for welding machines that do not have a built-in gas solenoid, such as many stick welders used for scratch-start TIG or older engine-driven welders. By giving you control at your fingertips, it ensures you save gas between welds while maintaining proper coverage during the arc.

This torch body is rated for approximately 200 Amps DC (at 60% duty cycle), making it robust enough for medium-to-heavy fabrication work on steel and stainless steel. It utilizes standard industry consumables, meaning you can easily find collets, collet bodies, and cups that fit this head without needing proprietary parts. Whether you are repairing a damaged torch or building a custom rig for field work, the ESAB HW-26V offers the reliability you need to keep welding.
