13N25 - Weldcraft 13N25 TIG Collet Body .020" (5-Pack)

High-Precision TIG Torch Component

The Weldcraft 13N25 Collet Body is an essential consumable engineered for the precise demands of Gas Tungsten Arc Welding (GTAW). Designed to accommodate .020-inch (0.5mm) tungsten electrodes, this component acts as the critical interface between the collet and the torch body, facilitating both the mechanical positioning of the electrode and the transfer of welding current. It is manufactured to strict tolerances to ensure seamless compatibility with all 9, 20, and 25 series TIG torches, including popular models like the WP-9 air-cooled and WP-20 water-cooled systems.

Fabricated from a high-grade copper alloy, the 13N25 collet body offers superior thermal and electrical conductivity. This material selection is vital for minimizing resistance heating at the contact points, thereby preserving the integrity of the torch head during operation. The internal geometry is machined to mate perfectly with the corresponding 13N series collet, ensuring a concentric grip on the fine .020" electrode. This mechanical stability is paramount for maintaining a consistent arc length and focal point, which is particularly challenging when welding thin-gauge materials requiring low amperage.

In the context of gas management, the standard collet body helps align the electrode within the ceramic cup, contributing to the laminar flow of shielding gas around the weld pool. While distinct from a gas lens system, this standard body provides robust and reliable performance for a wide range of general fabrication tasks. The product is supplied in a package of five, allowing maintenance teams and operators to keep an adequate stock of spares, ensuring that production is not halted due to consumable wear or damage.

Adhering to OEM specifications, genuine Weldcraft parts like the 13N25 prevent common issues associated with ill-fitting generic components, such as thread galling or gas leakage. Regular inspection of the collet body for signs of thermal fatigue or mechanical deformation is recommended to maintain the highest quality weld output.
