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

Heavy-Duty ESAB HW-26RV TIG Torch Body

Upgrade or repair your TIG welding setup with the ESAB HW-26RV Torch Body (Part Number 598478R). This air-cooled torch head is designed for welders who need the power handling of a 26-series torch combined with the versatility of a manual gas valve. The HW-26RV is a "Rigid Valve" body, meaning it features a fixed neck angle and a fingertip control valve for shielding gas. This configuration is particularly popular for field applications, pipe welding, and maintenance repair operations where simple, robust equipment is preferred.

The inclusion of the gas valve on the torch body gives the operator full autonomy over gas flow. This is indispensable when using welding power sources that lack a built-in gas solenoid, such as many stick welders used for TIG applications. By simply turning the valve, you can initiate gas flow before the arc starts and maintain it after the arc is extinguished to ensure proper shielding of the cooling puddle and tungsten. The body is constructed from high-temperature resistant silicone rubber and copper components to ensure efficient current transfer and operator comfort.

As an air-cooled unit, the HW-26RV eliminates the complexity of water-cooling systems while still offering a substantial amperage rating, generally around 200 amps at 60% duty cycle (depending on specific setup and gas). It utilizes standard 10N and 57N series consumables, ensuring that replacement parts like cups, collets, and back caps are readily available and affordable. This body is a direct replacement for worn-out HW-26 style heads and fits standard handles and cable assemblies designed for this series.

Benefits for the Welder:

• Manual Gas Control: Essential for TIG rigs on engine drives or stick machines.
• Robust Air-Cooled Power: Handles thicker materials without the bulk of water lines.
• Cost-Effective Maintenance: Replace just the body rather than the entire torch assembly.
• Proven Reliability: ESAB's manufacturing ensures a tight fit and long service life.
• Versatile Application: Suitable for mild steel, stainless steel, and aluminum welding tasks.
