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

Heavy-Duty Air-Cooled TIG Head with Valve

For professional welders requiring a robust solution for field welding and shop fabrication, the ESAB HW-26V Body W/Valve (598478) represents the gold standard in air-cooled TIG torch design. This torch body belongs to the heavy-duty 26-series family, known for its ability to handle higher amperages—typically up to 200A DC—without the complexity and weight of a water-cooled system. The "V" designation indicates the presence of a knurled manual gas valve located on the neck of the torch body, providing critical functionality for specific power source configurations.

The manual gas valve is particularly advantageous when pairing TIG torches with CC (Constant Current) power sources that lack internal gas management, such as "buzz boxes" or generator welders. The operator can initiate gas flow prior to the arc strike (pre-flow) and maintain it after the arc is extinguished (post-flow) to protect the tungsten and the weld pool from oxidation. This level of control is vital for producing X-ray quality welds in remote locations where sophisticated TIG inverters may not be available.

Constructed with high-grade copper components and high-temperature silicone rubber insulation, the HW-26V resists cracking and electrical tracking even under thermal stress. The head angle is designed for optimal ergonomics, reducing wrist strain during out-of-position welding. It accepts all standard 10N and 57N series consumables, allowing for a wide range of cup sizes and tungsten diameters (typically up to 5/32").
