13N27 - Weldcraft 13N27 1/16-inch TIG Collet Body (5-Pack)

Precision Engineered TIG Consumable: Weldcraft 13N27

The Weldcraft 13N27 Collet Body is a fundamental component for Gas Tungsten Arc Welding (GTAW) systems, specifically engineered to accommodate 1/16-inch (1.6mm) tungsten electrodes. As a critical interface within the torch head assembly, this collet body performs two primary functions: it secures the collet to hold the electrode in place and transfers the welding current from the torch body to the tungsten. Manufactured to rigorous OEM tolerances, the 13N27 ensures a concentric fit that minimizes runout and promotes a stable, focused arc, which is essential for high-precision welding applications in aerospace, motorsports, and industrial fabrication.

This component is part of the standard "2 Series" consumable line, making it widely compatible with a broad spectrum of TIG torches. It is designed for use with air-cooled 9-series torches and water-cooled 20 and 25-series torches. Specific compatible models include the Miller Weldcraft A-125, W-200 Pencil Flex, W-225 Pencil, W-250, W-280, W-310, W-375, A-200 Modular, A-150 Auto, and W-250 Auto TIG Torches. The versatility of the 13N27 makes it a staple inventory item for shops utilizing multiple torch configurations.

Constructed from a high-grade copper alloy, the Weldcraft 13N27 offers superior thermal conductivity. This material choice aids in the rapid dissipation of heat generated during the welding process, thereby protecting the torch head from overheating and extending the service life of the consumable itself. Unlike inferior generic alternatives, genuine Weldcraft parts feature precise threading that prevents cross-threading and ensures a gas-tight seal, reducing the risk of atmospheric contamination in the weld pool. This pack contains five collet bodies, providing a reliable supply for maintenance and ensuring consistent performance across multiple welding stations.

Proper maintenance of the torch front end is vital for weld quality. Over time, collet bodies can suffer from heat deformation or thread wear, leading to poor current transfer or gas turbulence. Replacing worn components with the 13N27 restores the electrical efficiency and gas shielding capabilities of the torch, ensuring that operators can achieve X-ray quality welds consistently.
