6CB418 - CK Worldwide 2 Series Short Collet Body 1/8" (3.2mm)

CK 6CB418 Short Collet Body Overview

The CK 6CB418 is a specialized short collet body designed for use with 2 Series TIG torches, including the popular WP-9 and WP-20 models. Engineered by CK Worldwide, this component is essential for welders requiring a compact torch setup to access confined spaces or achieve precise arc control. The collet body is machined to strict tolerances, ensuring a perfect fit for 1/8-inch (3.2mm) tungsten electrodes.

In the TIG welding process, the collet body plays a critical role in transferring welding current to the electrode and directing shielding gas flow. The 6CB418 is manufactured from high-grade tellurium copper alloy, which provides superior electrical conductivity and heat resistance compared to standard generic parts. This ensures stable arc performance and prolongs the lifespan of the consumable, reducing downtime for industrial operations.

Compatibility and Application

This short collet body is part of the 2 Series consumable line. It is compatible with a wide range of air-cooled and water-cooled torches, including:

• Air Cooled: WP-9, CK9, CK100, CK110, CK130


• Water Cooled: WP-20, WP-25, CK200, CK230, CK230FL2L

It is designed to be used in conjunction with matching short collets and back caps to minimize the overall length of the torch head. This configuration is particularly useful in pipe welding, aerospace applications, and automotive fabrication where clearance is limited.

Technical Specifications

The CK 6CB418 is rated for the amperage capacities of standard 2 Series torches. It securely holds 3.2mm tungsten, preventing slippage during welding. Regular inspection and replacement of collet bodies are recommended to maintain optimal gas coverage and prevent contamination of the weld pool.
