598478R - HW-26RV Air Cooled TIG Torch Head with Valve

ESAB HW-26RV TIG Torch Body with Valve (598478R)

The ESAB HW-26RV is a premium replacement TIG torch body designed for heavy-duty air-cooled applications. Known for its robustness and reliability, this torch body is part of the Heliarc™ line, providing welders with a durable tool for demanding industrial environments. The "RV" designation indicates a Rigid neck with a built-in gas Valve, making it an essential component for welding setups that require manual gas control directly at the torch, such as scratch-start or lift-arc TIG welding on power sources without an internal gas solenoid.

Rated for approximately 200 amps, the HW-26 series is the workhorse of air-cooled TIG torches. It handles higher amperages than the smaller 17 series while remaining air-cooled, eliminating the need for a water cooler. This specific body (598478R) is engineered to ESAB's high standards, ensuring excellent conductivity and heat resistance. The integrated valve is smooth to operate, allowing precise control over pre-flow and post-flow shielding gas, which is critical for protecting the tungsten electrode and the weld pool from contamination.

This torch body is compatible with standard 26-series consumables, including collets, collet bodies, gas lenses, and alumina cups, making it easy to integrate into your existing inventory of TIG parts. Whether you are replacing a damaged torch head or building a custom TIG rig for field work, the ESAB HW-26RV offers the performance and longevity professional welders expect. Its rigid neck provides a stable and consistent angle for general-purpose welding tasks.

Key Features:

• Integrated Gas Valve: Allows for manual control of shielding gas, perfect for machines without gas solenoids.
