Esab 0157123018 Tig Torch Collet Body 1/8 Inch

Product Description

The ESAB 0157123018 is a 1/8 inch collet body designed for TIG welding torches. The collet body secures the tungsten electrode inside the torch head, maintaining proper alignment and electrical contact during the welding arc. It is a wear item replaced during routine torch maintenance by welders and fabricators in both shop and field settings. This part corresponds to industry standard number 10N28 and is sized for 1/8 inch tungsten electrodes. The compact size and low individual weight make it practical to stock in multiples for ongoing service work.

This collet body is suited for use in light-duty to medium-duty TIG welding applications across manufacturing, metal fabrication, maintenance and repair, and pipe welding environments. It fits the HW17, HW18, and HW26 torch series, which are commonly found in both industrial and vocational welding setups. Installers and welding technicians replace collet bodies when electrode grip weakens, when the bore shows wear, or during full torch rebuild service.

Installation Notes

Collet body replacement is performed by a qualified welder or welding equipment technician. Always disconnect the torch from the power source and allow the torch to cool completely before disassembling the torch head. Remove the back cap, electrode, and collet before extracting the collet body. Inspect the torch body threads and gas lens seat for wear or contamination before installing the replacement collet body.
