53N16 - 53N16 Collet for 24 Series TIG Torch - .040 Inch (2-Pack)

Technical Overview of the 53N16 Collet

The 53N16 Collet is a critical consumable component designed specifically for the 24 Series TIG torch platform, which includes models such as the Weldcraft WP-24 and the legacy Linde HW-24. This component is precision-manufactured to accommodate tungsten electrodes with a diameter of .040 inches (1.0mm). The collet functions as the primary electrical contact point between the torch power cable and the electrode, necessitating high-grade copper alloy construction to ensure minimal electrical resistance and efficient thermal transfer.

In the assembly of a 24 Series torch, the collet is positioned within the collet body. As the back cap is tightened, axial force is applied to the collet, compressing its split-end design against the tapered interior of the collet body. This mechanical action secures the tungsten electrode in place, preventing slippage during operation and ensuring the electrode remains centered within the gas stream. The 53N16 is engineered with tight tolerances to match the specific geometry of the 24 Series front-end parts, which are significantly smaller than standard 17/18/26 series consumables due to the micro-torch design intended for confined spaces.

Proper maintenance of the collet is essential for arc stability. Over time, thermal cycling and mechanical stress can cause the collet to deform, twist, or lose its spring tension. A compromised collet may lead to poor arc starts, wandering arcs, or overheating of the torch head due to increased resistance. This generic replacement part adheres to the dimensional standards of the OEM 53N16, providing a reliable fit and consistent performance for precision TIG applications. It is supplied in a package of two, allowing operators to maintain a ready stock of spares for critical welding tasks.
