54N16 - Weldcraft 54N16 Alumina Gas Lens Nozzle #6 (3/8") - 10 Pack

High-Performance Alumina Gas Lens Nozzle

The Weldcraft 54N16 Alumina Gas Lens Nozzle is a premium consumable designed for professional TIG welding applications requiring superior shielding gas coverage and durability. Manufactured from high-grade alumina ceramic, this nozzle exhibits exceptional thermal conductivity and impact resistance, significantly reducing the risk of cracking under high-amperage thermal cycling. It is engineered to withstand the rigorous demands of industrial fabrication environments.

This #6 size nozzle features a 3/8-inch (9.5mm) bore, optimized for medium-amperage applications where a balance between gas coverage and accessibility is required. Unlike standard nozzles, the 54N16 is designed specifically for use with gas lens collet bodies. The gas lens system creates a laminar flow of shielding gas, reducing turbulence and minimizing atmospheric contamination of the weld pool. This laminar flow allows the operator to extend the tungsten electrode further beyond the nozzle face—improving visibility and access to tight joints such as fillets and pipe roots without compromising shielding integrity.

Compatible with all major 17, 18, and 26 series TIG torches (3 Series), the 54N16 integrates seamlessly into existing torch setups. Its standardized threading ensures a secure fit with 45V-series gas lenses. The nozzle's smooth surface finish resists spatter adhesion, simplifying post-weld cleaning and extending the consumable's usable life. Supplied in a convenient pack of 10, these nozzles ensure that operators have a reliable supply of high-quality consumables on hand to maintain productivity and weld quality.
