Esab 0157121016 Gas Lens Tig Torch Collet Body 1mm

Product Description

The ESAB 0157121016 is a 1mm gas lens collet body designed for TIG welding torch assemblies. The collet body serves as the holding component that grips the tungsten electrode and channels shielding gas through a lens screen to produce a laminar, stable gas flow around the weld zone. This design reduces turbulence and improves arc stability, which is especially valuable when welding thin or reactive materials. Licensed welding professionals and skilled fabricators install this component as part of routine torch consumable maintenance. It weighs 0.01 pounds and is sold individually, with a minimum order quantity of 10 units.

This collet body is intended for use in TIG torch assemblies that accept 1mm tungsten electrodes and gas lens hardware. It is suited to both light industrial and precision fabrication applications where consistent shielding gas coverage is required. The gas lens configuration is commonly used on stainless steel, aluminum, and titanium weldments where porosity and contamination must be minimized. This part ships as a single unit and is typically stocked in multiples to support ongoing torch consumable inventory.

Key Features

• Gas lens collet body design promotes laminar shielding gas flow for improved arc stability
• Sized for 1mm tungsten electrode diameter
• Compatible with HW-17, HW-18, and HW-26 TIG torch platforms
• Lightweight at 0.01 pounds, minimizing added torch mass
• Sold as a single unit per package; order in multiples of 10

Compatibility

Designed for use with HW-17, HW-18, and HW-26 TIG torch collet body assemblies. Industry standard reference number 45V42 applies to this component.

Installation Notes

Installation is performed by a qualified welder or welding equipment technician. Disconnect the torch from the power source and shut off shielding gas supply before disassembling the torch head. Thread the collet body into the torch head by hand first to avoid cross-threading, then snug with the appropriate torch wrench. Inspect the gas lens screen for damage or clogging during each consumable change to maintain proper gas coverage.
