Lincoln Electric KP4749-332 Tig Torch Collet Copper Alloy

Product Description

The LINCOLN ELECTRIC KP4749-332 is a replacement collet designed for use in 9/20 series TIG torches. The collet holds and centers the tungsten electrode within the torch body, maintaining proper electrical contact and alignment during the TIG welding process. Machined from copper alloy, it provides reliable conductivity and dimensional stability under the thermal demands of arc welding. This collet is sized for 3/32-inch tungsten electrodes, with a bore diameter of 0.094 inches. It is a consumable component replaced by welding technicians during routine torch maintenance or when electrode grip degrades.

This collet fits 9/20 series TIG torches and is suited for both shop and field welding environments where 3/32-inch tungsten electrodes are standard. Typical applications include light to medium-duty TIG welding on steel, stainless steel, and aluminum in fabrication, maintenance, and repair settings. Welding technicians performing torch rebuilds or consumable restocking will find this a direct-fit replacement for worn or damaged collets in compatible torch assemblies.

Key Features

• Copper alloy construction for high electrical conductivity and heat resistance
• 0.094-inch bore diameter sized for 3/32-inch tungsten electrodes
• Designed for 9/20 series TIG torch bodies
• Direct OEM-style replacement for worn or damaged collets
• Compact form factor for straightforward torch reassembly

Compatibility

Designed for use with 9/20 series TIG torches using 3/32-inch tungsten electrodes.

Installation Notes

Installation is performed by welding technicians during torch maintenance or consumable replacement. Disconnect the torch from the power source and allow it to cool completely before disassembling the torch head. Remove the existing collet, insert the KP4749-332, and reassemble the torch body snugly without over-tightening the back cap. Follow the torch manufacturer's service instructions and applicable workplace safety procedures when handling TIG torch components.
