10N25S - Generic 10N25S 1/8-Inch Stubby TIG Collet (2-Pack)

Technical Overview of the Generic 10N25S Stubby Collet

The Generic 10N25S is a specialized TIG welding collet designed to facilitate the "stubby" conversion of standard 17, 18, and 26 series TIG torches. This component is critical for operators requiring reduced torch head length to access confined spaces or complex geometries. Unlike standard 10N-series collets which maintain the full length of the torch head, the 10N25S is significantly shorter, working in conjunction with a specific stubby collet body (typically part number 17CB20) to condense the front-end assembly.

Manufactured from high-grade copper alloy, this collet ensures efficient thermal and electrical conductivity, which is paramount for maintaining arc stability and preventing overheating at the contact point with the tungsten electrode. The collet is precision-bored to accommodate 1/8-inch (3.2mm) tungsten electrodes. Its split-design mechanics allow it to compress securely around the electrode when the back cap is tightened, ensuring a firm grip that prevents tungsten slippage during welding operations. The mechanical integrity of the collet is essential for consistent current transfer from the power cable to the electrode.

This component is categorized as a consumable due to the thermal cycling and mechanical wear it endures. Over time, the collet may deform or lose its elasticity, leading to poor arc starts or unstable welding conditions. The Generic 10N25S serves as a direct dimensional replacement for the Weldcraft 10N25S, offering full compatibility with industry-standard torch bodies including the air-cooled WP-17 and WP-26, and the water-cooled WP-18. It is not compatible with 9 or 20 series torches, which utilize a different consumable system natively.

Implementing a stubby collet system effectively bridges the gap between the heavy-duty current capacity of larger torches and the maneuverability of smaller micro-torches. This configuration is particularly advantageous in pipe welding, roll cage fabrication, and manifold repair where clearance is limited. The 10N25S is supplied in a pack of two, ensuring operators have immediate replacement stock available to minimize downtime.
