Esab 0157123060 Alumina Gas Lens Tig Nozzle Size 7

Product Description

The ESAB 0157123060 is an alumina gas lens nozzle designed for use with TIG welding torches. This Size 7 nozzle features an 11mm orifice and is machined from alumina ceramic, a material well suited to the high-heat environment of TIG welding. It seats into gas lens torch bodies, working with the gas lens collet body to produce a laminar shielding gas flow that improves arc stability and weld quality. Licensed welders and field technicians installing or replacing nozzle consumables on TIG torch setups will find this a direct-fit replacement component. Industry standard reference 54N14 applies to this nozzle.

This nozzle is rated for use with the HW17, HW18, and HW26 torch series. These are common air-cooled and water-cooled TIG torches found in fabrication shops, pipe welding, maintenance welding, and precision sheet metal work. The gas lens configuration makes this nozzle appropriate for applications requiring extended electrode stickout or improved shielding gas coverage, such as welding in tight joint geometry or on reactive metals like titanium and stainless steel.

Key Features

• 11mm orifice diameter provides adequate shielding gas coverage for Size 7 torch applications
• Alumina ceramic construction withstands high radiant heat from the TIG arc
• Gas lens-compatible design promotes laminar shielding gas flow for improved arc stability
• Conforms to industry standard 54N14 for broad interchangeability
• Compatible with HW17, HW18, and HW26 torch bodies

Compatibility

Designed for use with ESAB HW17, HW18, and HW26 TIG torch series. Conforms to industry standard number 54N14. Sized as a direct replacement for Size 7 gas lens nozzle applications on these torch bodies.

Installation Notes

Installation should be performed by a qualified welder or welding equipment technician. Shut off the shielding gas supply and ensure the torch is disconnected from the power source before replacing the nozzle. Alumina ceramic nozzles are brittle and should be threaded in by hand without tools to avoid cracking. Inspect the collet body and gas lens for contamination or wear whenever the nozzle is replaced.
