53N58 - Weldcraft 53N58 Alumina Gas Lens Cup #4 (10-Pack)

Weldcraft 53N58 Alumina Gas Lens Nozzle Overview

The Weldcraft 53N58 is a premium Alumina Gas Lens Nozzle designed to meet the rigorous demands of precision TIG welding. Manufactured from high-quality alumina ceramic, this nozzle offers superior thermal conductivity and resistance to high-impact environments. It is specifically engineered to interface with gas lens collet bodies, a configuration that significantly improves the laminar flow of shielding gas compared to standard collet bodies. This reduction in turbulence is critical for maintaining a clean weld pool and preventing atmospheric contamination, particularly when welding reactive metals or high-grade alloys.

This specific nozzle is a Size #4, featuring a 1/4-inch (6.4 mm) orifice diameter. It is fully compatible with a wide range of air-cooled and water-cooled TIG torches, including the 9, 20, 22, 24, and 25 series. The standardized threading ensures a secure fit with compatible gas lenses, preventing gas leakage at the cup connection. The alumina material composition is selected for its ability to withstand rapid thermal cycling without cracking, a common failure mode in lower-quality ceramic cups. Additionally, the surface finish of the Weldcraft 53N58 resists the adhesion of weld spatter, simplifying post-weld maintenance and prolonging the service life of the consumable.

Industrial professionals rely on genuine Weldcraft parts for their consistency in manufacturing tolerances. In automated or high-precision manual welding, variations in nozzle geometry can affect gas coverage and arc stability. The 53N58 ensures reliable performance, making it a staple inventory item for fabrication shops utilizing compatible TIG torch systems. This product is supplied in a package of 10, providing an economical solution for high-volume welding operations requiring regular consumable replacement.
