Compatibility Note: These collet chucks are intended for CK Worldwide MR70 and MR140 Micro TIG torches. They are not universal TIG torch collets. Confirm your torch model and tungsten diameter before ordering.

Designed for Precision Micro TIG Welding

CK Worldwide MR70 and MR140 Micro TIG torches are designed for welding applications where a compact torch head and precise electrode positioning are important.

The collet chuck is a key component of the Micro Torch assembly, helping secure the tungsten electrode during welding.

Using the correct collet chuck size helps maintain proper electrode fit and reduces the possibility of unwanted tungsten movement during operation.

These replacement collet chucks are useful for maintaining the torch's original configuration when an existing chuck becomes worn or damaged.

Choosing the Correct Collet Chuck Size

Always match the collet chuck diameter to the tungsten electrode being used.

• .040" (1.0mm): Use with .040" tungsten electrodes.
• 1/16" (1.6mm): Use with 1/16" tungsten electrodes.
• 3/32" (2.4mm): Use with 3/32" tungsten electrodes.

For example, if your MR70 or MR140 Micro TIG Torch uses a 1/16" tungsten electrode, select the CK-MR116C collet chuck.

Important: The collet chuck must match the tungsten diameter to provide the proper fit. Do not use an incorrectly sized chuck to hold a smaller or larger tungsten electrode.

How This Product Is Sold
