10N31 - Weldcraft 10N31 1/16" Collet Body (5-Pack) for 17/18/26 Torches

Precision TIG Consumables for Professional Fabrication

The Weldcraft 10N31 Collet Body is a critical component designed for precision TIG welding applications. Engineered to accommodate 1/16-inch (1.6mm) tungsten electrodes, this collet body serves as the foundational interface between the electrode, the collet, and the torch body. It is manufactured from high-grade brass, a material selected for its excellent balance of thermal conductivity, electrical transmission properties, and mechanical durability under thermal cycling. This specific model is part of the industry-standard "3 Series" consumables, making it universally compatible with the widely used 17, 18, and 26 series TIG torches, including both air-cooled and water-cooled variants.

In the TIG welding assembly, the collet body performs two primary functions: it houses the collet which grips the tungsten, and it contains the gas orifices that distribute shielding gas into the ceramic cup. The 10N31 is a standard collet body, distinct from gas lens varieties, offering a robust and cost-effective solution for general welding tasks where standard gas coverage is sufficient. Its precise machining ensures that the tungsten electrode remains centered within the gas cup, a vital factor for maintaining arc stability and preventing weld contamination. The threading is manufactured to tight tolerances to ensure a secure fit into the torch head, preventing gas leaks that could compromise the weld pool.

Professional fabricators understand that the quality of consumables directly impacts the quality of the arc. Inferior collet bodies can suffer from poor threading, inconsistent gas flow holes, or soft alloys that deform under heat, leading to poor current transfer and arc wandering. By choosing genuine Weldcraft components, operators ensure consistent performance. This product is supplied in a pack of five, facilitating efficient inventory management for industrial environments where minimizing downtime is a priority. Whether used in aerospace, automotive, or general fabrication, the 10N31 provides the reliability required for high-quality TIG welding.

Regular inspection of collet bodies is recommended as part of a preventative maintenance schedule. Over time, heat cycles can cause oxidation or deformation, and spatter can clog gas ports. Replacing the collet body when signs of wear appear ensures that the shielding gas flow remains laminar and the electrical connection to the tungsten remains solid. This 5-pack ensures that a fresh replacement is always available when needed.
