10N50 - Alumina TIG Cup #4 (1/4") for 17/18/26 Torches - 10N50

Industrial Grade Alumina TIG Nozzle 10N50

The Generic 10N50 Alumina Nozzle is a fundamental consumable for TIG welding professionals utilizing standard 3-series torches. Engineered from high-impact alumina ceramic, this nozzle is designed to withstand the intense thermal cycling inherent in Gas Tungsten Arc Welding (GTAW). The 10N50 is a size #4 cup, featuring a 1/4-inch (6.4mm) orifice, making it an excellent choice for applications requiring tight access or focused shielding gas coverage on thinner materials.

Compatibility is a key feature of this component. It is manufactured to precise industry standards to ensure a perfect fit with all major brands of 17, 18, and 26 series TIG torches, including Weldcraft, Miller, Lincoln, and CK Worldwide. Whether you are operating an air-cooled 17 or 26 torch, or a water-cooled 18 series torch, this nozzle threads securely onto the standard collet body (10N series) to direct argon flow efficiently over the weld pool.

Alumina ceramic is chosen for its balance of durability and cost-effectiveness. It offers significant resistance to thermal shock, reducing the likelihood of cracking during rapid heating and cooling cycles. Additionally, the smooth surface finish helps minimize spatter adhesion, although regular inspection and cleaning are recommended to maintain optimal gas flow characteristics. This nozzle is not designed for use with gas lenses; it is intended for standard collet body setups.

For industrial MRO operations, maintaining a stock of 10N50 nozzles is essential to prevent downtime. As a consumable that is directly exposed to the arc environment, the nozzle will eventually degrade or accumulate debris. This generic replacement part provides a reliable, high-quality alternative to OEM parts, delivering consistent performance for mild steel, stainless steel, and aluminum welding tasks.
