0157123012 - ESAB 3/32" TIG Collet for HW-17/18/26 Torches (10-Pack)

Technical Overview of ESAB 3/32" Collet

The ESAB 0157123012 is a standard industrial TIG welding collet designed for use with 3/32-inch (2.4mm) tungsten electrodes. Manufactured from high-grade copper alloy, this component is critical for the electrical interface between the TIG torch and the tungsten electrode. It functions by compressing against the electrode when the back cap is tightened, ensuring both mechanical retention and electrical continuity.

This specific collet is engineered to fit the industry-standard 17, 18, and 26 series TIG torches, including ESAB's own Heliarc HW-17, HW-18, and HW-26 models. It corresponds to the universal part number 10N24. The split-body design allows for the necessary radial compression required to hold the tungsten firmly in place during welding operations. Proper collet sizing is essential to prevent arcing inside the torch head and to maintain a stable welding arc.

Supplied in a pack of 10, these collets are consumable items that degrade over time due to thermal cycling and mechanical wear. Regular inspection and replacement are recommended to maintain optimal torch performance. The copper material provides excellent thermal conductivity, helping to dissipate heat away from the electrode contact point, although it is distinct from the collet body which manages the primary gas distribution.
