13N08 - Weldcraft 13N08 #4 Alumina TIG Cup (10-Pack)

Technical Overview of Weldcraft 13N08 Alumina Nozzles

The Weldcraft 13N08 Alumina Nozzle is a standard consumable component designed for precision TIG welding applications. Manufactured from high-grade alumina ceramic, this nozzle offers a balance of impact resistance and thermal stability, making it suitable for general-purpose welding in various industrial environments. The #4 size designation indicates an orifice diameter of 1/4 inch (6.4 mm), which provides a focused shielding gas stream ideal for accessing tight corners or welding on thinner gauge materials where a narrower gas column is required.

Alumina (aluminum oxide) is chosen for these nozzles due to its high dielectric strength and ability to withstand the intense radiant heat generated during the GTAW process. Unlike lower-grade ceramics, Weldcraft's alumina composition resists thermal shock, reducing the likelihood of cracking during rapid heating and cooling cycles. This specific nozzle, part number 13N08, is engineered to thread directly onto standard collet bodies found in 9, 20, 22, and 25 series TIG torches. It ensures a gas-tight seal to prevent atmospheric contamination of the weld pool.

Industrial operators appreciate the consistency of genuine Weldcraft parts. The manufacturing tolerances of the 13N08 ensure that the gas flow remains laminar as it exits the cup, minimizing turbulence that could lead to porosity. This 10-pack configuration is optimized for MRO (Maintenance, Repair, and Operations) inventory management, ensuring that welding stations remain operational with minimal downtime due to consumable depletion.
