Esab 0157121018 Tig Torch Collet Body HW-17 HW-18 HW-26

Product Description

The ESAB 0157121018 is a replacement collet body designed for use with Heliarc TIG welding torches. The collet body secures the tungsten electrode inside the torch head, maintaining proper alignment and ensuring consistent arc stability during gas tungsten arc welding (GTAW) operations. It is a precision consumable component that must be matched to the correct torch model and tungsten diameter to function properly. Licensed welders and professional fabricators performing TIG welding on ferrous and non-ferrous metals rely on collet bodies as routine service parts to maintain torch performance.

This collet body is compatible with the HW-17, HW-18, and HW-26 series Heliarc TIG torch configurations. These torches are widely used in industrial fabrication, maintenance and repair, and precision welding applications across sheet metal, pipe, and structural work. The 0157121018 is a single-piece replacement item sold individually, making it well suited for field service kits and torch maintenance inventories.

Key Features

• Direct OEM-style replacement collet body for Heliarc TIG torches
• Compatible with HW-17, HW-18, and HW-26 torch models
• Secures tungsten electrode for stable arc and consistent weld quality
• Sold as a single unit for straightforward consumable restocking

Compatibility

Designed for use with ESAB Heliarc HW-17, HW-18, and HW-26 TIG torch bodies. Verify tungsten diameter and torch series before ordering to confirm proper collet body fitment.

Installation Notes

Collet body replacement is performed by qualified welders or welding equipment technicians. Always disconnect the torch from the power source and shielding gas supply before disassembling the torch head. Avoid overtightening the back cap or collet nut, as this can deform the collet body and damage the tungsten seating surface. Inspect the collet, gas lens, and nozzle for wear when replacing the collet body.
