OVERVIEW

Technical Specification: Weldcraft 10N50 Alumina Nozzle

The Weldcraft 10N50 Alumina Nozzle is a critical consumable designed for Gas Tungsten Arc Welding (GTAW) applications requiring precision and durability. Manufactured from high-grade alumina ceramic (Al2O3), this nozzle offers an optimal balance of thermal conductivity, dielectric strength, and mechanical robustness. The alumina composition is specifically engineered to withstand the high-temperature environment of the TIG arc without degrading or fracturing under thermal shock, making it a standard choice for general-purpose fabrication.

This specific nozzle is designated as size #4, which corresponds to an orifice diameter of 1/4 inch (approximately 6.4 mm). The smaller bore size is particularly advantageous for applications requiring focused gas coverage or when accessing tighter joints where a larger cup would obstruct the welder's view or contact the workpiece. The nozzle features standard industry threading, ensuring seamless compatibility with all major brands of 17, 18, and 26 series TIG torches (often referred to as the "3-series" or large-body torches). This universal fitment allows for easy integration into existing inventory systems for workshops utilizing air-cooled 17/26 torches or water-cooled 18 torches.

The 10N50 nozzle attaches directly to the collet body of the torch assembly. Its ceramic construction provides necessary electrical insulation, preventing the energized torch components from shorting against the workpiece. Furthermore, the material's resistance to spatter buildup ensures consistent laminar gas flow, which is essential for preventing atmospheric contamination of the weld pool. This product is supplied in a pack of 10, facilitating efficient inventory management for high-throughput industrial environments.

FAQ

The 10N50 nozzle fits all 17, 18, and 26 series TIG torches. This includes air-cooled 17 and 26 models, as well as water-cooled 18 models from Weldcraft, Miller, CK Worldwide, and other major brands.

A #4 nozzle has an inside diameter of 4/16ths of an inch, which equals 1/4 inch or approximately 6.4 millimeters.

This product is sold as a package of 10 individual nozzles.

Alumina (pink) nozzles are made from high-grade ceramic and offer better impact and heat resistance compared to lava nozzles. They are the industry standard for general TIG welding.

No, the 10N50 is a standard nozzle designed to thread onto a standard collet body. It is not compatible with gas lens collet bodies (which typically use the 54N series nozzles).

Yes, alumina nozzles are suitable for both DC welding on steel/stainless and AC welding on aluminum.

Yes, this is a genuine Weldcraft (Miller) product, part number 10N50.

You would choose a #4 cup for welding in tight corners, for intricate detail work, or when you need to conserve shielding gas on smaller welds.
