53N61S - Weldcraft 53N61S #8 Alumina Gas Lens Cup (10-Pack)

Technical Overview of the Weldcraft 53N61S Alumina Nozzle

The Weldcraft 53N61S is a specialized Alumina Gas Lens Nozzle designed to optimize shielding gas coverage in Gas Tungsten Arc Welding (GTAW) applications. Engineered with a #8 orifice, which corresponds to a 1/2-inch (12.7mm) exit diameter, this nozzle is critical for welders requiring a broader envelope of inert gas to protect the weld pool from atmospheric contamination. The nozzle is manufactured from high-grade alumina ceramic, a material selected for its exceptional thermal conductivity, high impact resistance, and ability to withstand the extreme thermal shock cycles inherent in TIG welding.

This component is specifically categorized as a "Gas Lens" nozzle. Unlike standard nozzles that thread onto a standard collet body, the 53N61S threads onto a gas lens collet body (such as the 45V series). The internal geometry of the nozzle works in conjunction with the gas lens mesh screens to laminarize the flow of argon or helium. This laminar flow allows for a longer tungsten stick-out, providing the operator with better visibility of the puddle and improved access to tight joints without sacrificing shielding integrity. The 53N61S features a standard length of approximately 1-3/16 inches, making it a versatile choice for general fabrication.

Compatibility is a key feature of the 53N61S. It is designed to fit the "2 Series" front-end parts, which encompasses a wide range of air-cooled and water-cooled torches. Specifically, it is compatible with Weldcraft (and equivalent) WP-9, WP-20, WP-22, WP-24, and WP-25 series torches. It is also suitable for various sub-models including 9F, 9FV, 20M, 20F, and 24W. This nozzle is rated for TIG amperage ranges typically found in these torch classes, handling duty cycles appropriate for both light-duty air-cooled and heavy-duty water-cooled applications (80 A - 250 A depending on the torch setup). This product is supplied in a package of 10, ensuring facilities have adequate stock for consumable replacement.
