13N25 - Weldcraft 13N25 TIG Collet Body .020" for 9/20 Series Torches (5-Pack)

Precision TIG Components for Micro-Welding

The Weldcraft 13N25 Collet Body is a critical consumable designed specifically for the finest TIG welding applications. Engineered to accommodate 0.020-inch (0.5mm) tungsten electrodes, this collet body is essential for operators performing micro-welding tasks where precision and arc stability are paramount. As a genuine Weldcraft product, it meets rigorous manufacturing standards, ensuring that the internal geometry perfectly matches the corresponding collet to provide a secure grip on the electrode without slippage or deformation.

Constructed from a high-purity copper alloy, the 13N25 offers excellent thermal and electrical conductivity. This material choice minimizes resistance heating at the torch head, which is crucial even at the lower amperages typically used with .020" tungsten. Efficient heat transfer helps prolong the life of the consumable and the torch head itself. The component is designed to thread seamlessly into standard 9, 20, and 25 series TIG torch bodies, acting as the housing that compresses the collet against the tungsten when the back cap is tightened.

This 5-pack configuration ensures that professional fabricators have ready replacements on hand. In precision environments such as electronics repair, medical device manufacturing, or aerospace instrumentation, the integrity of the torch consumables directly impacts the quality of the weld. Worn or damaged collet bodies can lead to poor gas coverage or erratic arcs. By utilizing the 13N25, users ensure their equipment remains in peak condition for the most delicate welding operations.

Compatibility is broad within the small-body torch category. Whether using an air-cooled WP-9 or a water-cooled WP-20 or WP-25, this collet body serves as the standard interface for the smallest available tungsten diameter. It is not compatible with gas lens setups; it is a standard collet body intended for use with standard alumina nozzles.
