11N65 - ESAB 11N65 Collet Body for HW-12 TIG Torch - 1/4 Inch

Heavy-Duty TIG Welding Performance

The ESAB 11N65 Collet Body is a critical component designed for the rigorous demands of heavy industrial TIG welding. Specifically engineered for the HW-12 (Heliwelder 12) and WP-12 series torches, this collet body allows welders to utilize large diameter tungsten electrodes, specifically the 1/4-inch (6.4mm) size. In the world of welding, the collet body plays a dual role: it houses the collet that grips the electrode, and it acts as the primary transfer point for welding current from the torch cable to the tungsten itself. Because the HW-12 series is typically used for high-amperage applications—often exceeding 500 amps—the quality and conductivity of the collet body are paramount to maintaining a stable arc and preventing equipment failure.

Manufactured from premium-grade copper alloy, this component offers superior thermal and electrical conductivity. This ensures that the massive amount of energy required for heavy plate welding is transferred efficiently, minimizing resistance heating within the torch head. Poorly made consumables can lead to arc wandering, inconsistent starts, and rapid overheating, but the ESAB 11N65 is built to meet OEM specifications for reliability and longevity. It serves as the foundation for your TIG torch's front-end assembly, ensuring that the gas cup, collet, and tungsten all align perfectly for precision work.

Whether you are fabricating thick aluminum sections, repairing heavy machinery, or working in a foundry setting, using the correct consumables is essential for safety and quality. This collet body is designed to withstand the intense thermal cycles associated with water-cooled TIG welding. Regular inspection and replacement of collet bodies are recommended to maintain optimal gas coverage and electrical contact. By choosing the ESAB 11N65, you are investing in a part that supports the high-performance capabilities of your heavy-duty welding equipment, ensuring that your focus remains on the weld puddle rather than equipment troubleshooting.
