MR332C - CK MR332C 3/32-inch Micro Series TIG Collet Body

Precision Consumables for Micro TIG Applications

When performing intricate welding tasks that require the finesse of a Micro Series TIG torch, every component in your front-end assembly plays a critical role in the final weld quality. The CK MR332C Collet Body is a specialized consumable designed exclusively for CK Worldwide's Micro Series torches, including the popular MR70 and MR140 models. Engineered to handle the specific demands of precision fabrication, this collet body ensures that your tungsten electrode is held securely and concentrically, providing the stable arc required for delicate work on thin-gauge materials.

The MR332C is sized specifically for 3/32-inch (2.4mm) tungsten electrodes, a common size for medium-range micro welding applications where slightly higher amperage capacity is needed compared to the finest wires. Manufactured from high-grade copper alloy, this collet body offers excellent thermal and electrical conductivity. This is particularly important in micro torches, where heat dissipation is managed within a much smaller form factor than standard 17 or 26 series torches. By efficiently transferring current to the tungsten and helping to wick heat away from the front end, the MR332C helps prolong the life of your consumables and the torch head itself.

Using genuine CK Worldwide parts like the MR332C guarantees proper fitment and performance. Generic replacements often lack the tight manufacturing tolerances required for micro torches, leading to gas turbulence or poor electrical contact. With the CK MR332C, you can trust that your gas shielding will remain laminar and your arc will remain focused, allowing you to concentrate on the artistry of your weld. Whether you are repairing aerospace components, working on tool and die molds, or fabricating medical devices, this collet body is an essential component of your Micro TIG setup.

Key Benefits for the Welder

• Exact Fitment: Tailored specifically for the unique thread patterns and geometry of MR70 and MR140 Micro Torches.


• Stable Arc: Holds the tungsten firmly to prevent vibration or wandering during critical welds.


• Durable Construction: Made from robust copper alloy to withstand thermal cycling.


• Versatile Sizing: Accommodates 3/32" tungsten, bridging the gap between ultra-fine and standard welding tasks.
