8C116 - CK 8C116 1/16-Inch Collet for 8 Series TIG Torches (Replaces 53N14)

Precision Engineering for Micro-TIG Applications

The CK Worldwide 8C116 Collet is a critical consumable component designed specifically for the 8 Series line of TIG welding torches. Engineered to accommodate 1/16-inch (1.6mm) tungsten electrodes, this collet ensures the precise alignment and electrical connectivity required for high-quality welding operations. The 8 Series torches, including models such as the CK24, CK80, CK90, and CK180, are typically utilized in restricted-access applications or for fine-detail work where torch profile minimization is paramount. Consequently, the internal components, including the 8C116, must adhere to strict dimensional tolerances to maintain the compact form factor of the torch head while delivering reliable performance.

Manufactured from high-grade copper alloy, the 8C116 collet exhibits superior thermal and electrical conductivity. This material selection is essential for minimizing resistance heating at the point of contact between the power cable delivery system and the tungsten electrode. Efficient current transfer stabilizes the welding arc, which is particularly critical when operating at the lower amperage ranges often associated with 8 Series torch applications. The collet features a split-design mechanism that compresses against the tungsten electrode when the back cap is tightened, providing a secure mechanical grip that prevents electrode slippage during operation.

This component serves as a direct functional replacement for the industry-standard part number 53N14, ensuring broad compatibility with torches adhering to the 8 Series form factor, including those from Weldcraft, Lincoln, and other major manufacturers utilizing the 24-style head assembly. Proper maintenance of the collet is vital for process consistency; a worn or deformed collet can lead to poor arc starts, unstable arcs, and reduced consumable life. The CK 8C116 is machined to resist twisting and deformation, ensuring concentricity is maintained for the lifespan of the consumable.

Technical Specifications and Compatibility

The CK 8C116 is strictly compatible with 8 Series torch bodies. It is not interchangeable with the larger 2 Series (9/20) or 3 Series (17/18/26) consumables. Users must ensure their torch setup utilizes the 8 Series front-end parts. This collet pairs with the corresponding collet body and nozzle configurations standard to the CK24 and CK80 systems. It is rated for the full amperage capacity of the compatible torches, provided the duty cycle limits of the torch body are respected.
