13N11 - Weldcraft 13N11 Alumina TIG Cup #7 - 10 Pack

Reliable Gas Shielding for Precision TIG Welding

The Weldcraft 13N11 Alumina Nozzle is a critical consumable for professional TIG welders seeking consistent performance and durability. Sized as a #7 cup with a 7/16-inch (11mm) orifice, this nozzle is engineered to provide optimal shielding gas coverage for a wide variety of welding applications. Manufactured from high-grade alumina ceramic, these nozzles are designed to withstand the intense thermal cycling inherent in Gas Tungsten Arc Welding (GTAW). The material offers an excellent balance of impact resistance and thermal conductivity, ensuring that the nozzle maintains its structural integrity even during prolonged welding sessions at higher amperages.

This 10-pack configuration is ideal for industrial environments and busy fabrication shops where downtime must be minimized. The 13N11 is a standard consumable compatible with the popular 9 series (air-cooled) and 20 series (water-cooled) TIG torches, as well as 22, 24, and 25 series models. Its precise threading ensures a secure fit onto the collet body, preventing gas leakage that could compromise the weld pool. Unlike lower-quality generic alternatives, genuine Weldcraft parts are manufactured to strict tolerances, ensuring that the orifice remains perfectly centered for uniform gas distribution.

One of the standout features of the Weldcraft alumina composition is its resistance to spatter build-up. In TIG welding, keeping the cup clean is essential for maintaining laminar gas flow; these nozzles resist the adhesion of molten contaminants, making them easier to clean and extending their service life. Whether you are welding stainless steel, aluminum, or mild steel, the #7 cup size offers a versatile middle-ground coverage suitable for medium-sized joints and general fabrication tasks. By choosing the Weldcraft 13N11, operators ensure their equipment performs at the level required for aerospace, motorsports, and precision piping applications.
