363-1015 - CK Worldwide 10N47 Alumina Nozzle Cup #7 (7/16") for 17/18/26 Series Torches

High-Performance TIG Shielding with the 10N47 Alumina Nozzle

The CK Worldwide 10N47 Alumina Nozzle Cup is a standard consumable designed for precision TIG welding applications. Engineered to fit the widely used 17, 18, and 26 series TIG torches, this #7 size cup provides a 7/16-inch (11mm) orifice, offering an optimal balance of gas coverage and accessibility for a variety of joint configurations. Manufactured from high-grade alumina ceramic, this nozzle is built to withstand the intense thermal cycling and high heat associated with Gas Tungsten Arc Welding (GTAW).

Robust Ceramic Construction

Alumina (Aluminum Oxide) is the industry standard material for TIG nozzles due to its excellent electrical insulation properties and high thermal resistance. The 10N47 cup is impact-resistant and designed to resist cracking under thermal shock, ensuring a longer service life compared to lower-quality generic alternatives. This durability reduces downtime spent replacing consumables and ensures consistent shielding gas flow, which is critical for preventing atmospheric contamination of the weld pool.

Broad Torch Compatibility

This nozzle is designed as a direct replacement for the industry-standard 10N47 part number. It threads securely onto standard collet bodies (10N series) used in air-cooled and water-cooled torches. Specifically, it is compatible with:

• 17 Series: Air-cooled torches (150A).
• 18 Series: Water-cooled torches (350A).
• 26 Series: Air-cooled torches (200A).

Whether you are using a CK Worldwide torch or a compatible model from other major manufacturers like Miller (Weldcraft), Lincoln, or ESAB, this nozzle ensures a tight fit and reliable performance.

Optimized Gas Coverage

The #7 orifice size (7/16") is a versatile choice for general-purpose welding. It provides a gas shield wide enough to protect the tungsten electrode and the molten puddle during medium-amperage welding on steel, stainless steel, and aluminum. The smooth interior finish of the cup promotes laminar gas flow, reducing turbulence that can lead to porosity in the weld. This makes it an essential component for fabricators requiring high-quality aesthetic welds and structural integrity.
