MR116C - CK Worldwide MR116C 1/16-inch Micro Torch Collet Body

Precision TIG Components for Micro Applications

The CK Worldwide MR116C Collet Body is a specialized consumable designed exclusively for the CK Micro Series TIG torches, including the MR70 and MR140 models. In the realm of micro-welding, where precision is paramount, the quality of your torch consumables dictates the stability of your arc and the cleanliness of your weld. This 1/16-inch (1.6mm) collet body is engineered to hold the tungsten electrode firmly in place, ensuring perfect alignment within the gas cup for consistent shielding gas coverage.

Manufactured from high-grade copper alloy, the MR116C offers excellent thermal and electrical conductivity. This is particularly important in micro-torches where heat dissipation is critical due to the compact size of the head. By efficiently transferring current to the tungsten, this collet body helps maintain a focused and stable arc, which is essential when working on thin-gauge materials, electronics, or intricate aerospace components. The precise machining prevents arcing inside the torch head, prolonging the life of both the consumable and the torch itself.

Replacing your collet body regularly is a key maintenance step for professional TIG welders. A worn or deformed collet body can lead to poor gas flow, tungsten slippage, or erratic arc starts. The CK MR116C is built to OEM specifications, guaranteeing a perfect fit for your Micro Series torch setup. Whether you are performing delicate repairs or high-specification fabrication, trusting genuine CK Worldwide parts ensures your equipment operates at peak performance.

Key Technical Benefits

Using the correct collet body size is non-negotiable for safety and quality. The MR116C is specifically sized for 1/16" tungsten electrodes, a common size for the amperage ranges typically seen in micro-TIG applications. Its robust construction resists deformation under heat, providing a reliable grip on the tungsten throughout the welding cycle.
