53N18 - Weldcraft .040" Collet Body for WP-24 Series TIG Torches (5-Pack)

Precision TIG Components for Micro-Welding Applications

The Weldcraft 53N18 Collet Body is a critical consumable designed specifically for the WP-24 and WP-24W series of TIG torches. In the realm of precision welding, particularly where micro-torches are utilized for intricate aerospace, automotive, or instrumentation fabrication, the integrity of the electrical connection between the power source and the electrode is paramount. This collet body is engineered to accommodate a 0.040-inch (1.0mm) tungsten electrode, a standard size for fine-detail work requiring low amperage and high control.

Manufactured from high-grade copper alloy, the 53N18 ensures optimal thermal and electrical conductivity. This material choice aids in the dissipation of heat generated during the welding process, thereby extending the service life of both the collet body and the surrounding torch components. As an OEM part from Weldcraft (a Miller Electric brand), it adheres to strict dimensional tolerances. This precision ensures that the collet body threads smoothly into the torch head and seats the collet firmly, preventing the tungsten slippage that can occur with inferior aftermarket components.

For industrial procurement and maintenance, reliability is key. The 53N18 is supplied in a pack of five, allowing MRO managers to maintain adequate stock levels for production environments. Regular replacement of collet bodies is recommended to maintain arc stability; over time, thermal cycling and mechanical wear can degrade the threads and the internal seating surface, leading to poor current transfer and erratic arc starting. By utilizing genuine Weldcraft consumables, operators ensure that their WP-24 series torches perform to factory specifications, delivering the consistent results required for code-level welding.

This component is compatible exclusively with the 24 series front-end parts. It works in conjunction with the corresponding collet and nozzle (cup) to shape the shielding gas flow and secure the electrode. Its compact design is integral to the low-profile nature of the WP-24 torch, allowing welders to access tight corners and confined spaces without obstruction.
