13N13 - Alumina TIG Welding Nozzle Cup, Size #10 (5/8 Inch), 10-Pack

Precision Alumina Shielding for GTAW Applications

The Weldcraft 13N13 Alumina Nozzle is a critical consumable designed for the precision requirements of Gas Tungsten Arc Welding (GTAW). Engineered to fit the industry-standard 9 Series (air-cooled) and 20 Series (water-cooled) TIG torches, as well as the 25 Series, this nozzle ensures seamless compatibility with a wide range of welding equipment. The nozzle features a #10 orifice, corresponding to a 5/8-inch (approximately 16mm) bore diameter. This larger size is specifically advantageous for applications requiring a broader envelope of inert shielding gas, such as when welding reactive alloys like titanium or stainless steel, or when utilizing a longer tungsten electrode extension to reach into tight corners or fillets.

Manufactured from high-quality alumina (aluminum oxide) ceramic, the 13N13 offers a robust balance of thermal properties and mechanical strength. Alumina is the standard material for TIG nozzles due to its high melting point and excellent electrical insulating properties, preventing arc wandering and shorting against the workpiece. While alumina is resistant to the high heat generated by the welding arc, it is a ceramic material and should be handled with care to avoid impact damage. Users should also avoid rapid quenching in water, as thermal shock can cause cracking.

This product is supplied as a package of 10 nozzles, facilitating efficient inventory management for industrial environments. The threaded base is designed to mate perfectly with standard collet bodies (13N series), ensuring a gas-tight seal when seated against the torch insulator. It is important to note that this nozzle is designed for standard setups and is not compatible with gas lens collet bodies, which require the 53N series nozzles. For fabricators seeking reliable performance and consistent gas flow dynamics in their 9/20 series torch setups, the 13N13 remains a staple component.
