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

Reliable 10N47 #7 TIG Cup for 17/18/26 Torches

Upgrade your TIG torch setup with the 10N47 Alumina Nozzle Cup, a size #7 ceramic cup essential for everyday welding tasks. Designed for the popular 17, 18, and 26 series TIG torches, this consumable is a staple in any welder's toolkit. Whether you are working on an automotive exhaust, repairing farm equipment, or performing precision fabrication, having a fresh, high-quality nozzle is key to maintaining a stable arc and a clean weld puddle.

Why Choose Alumina?

Ceramic nozzles come in various grades, but standard alumina offers the best combination of cost-effectiveness and performance for general welding. It handles high amperage heat without melting or deforming. The pink-hued ceramic body is easily identifiable and provides the necessary electrical isolation to prevent arc wander or shorting against the workpiece. The 10N47 is designed to thread easily onto your collet body, creating a seal that directs your Argon shielding gas exactly where it is needed.

Versatile #7 Size Applications

The #7 cup features a 7/16-inch (approx. 11mm) bore. This intermediate size is perfect for a wide range of tungsten electrode diameters, typically from 1/16" (1.6mm) up to 3/32" (2.4mm). It offers better gas coverage than smaller #4 or #5 cups, allowing for slightly longer stick-out when reaching into corners, while not being as bulky as large gas lens cups. This makes it an excellent "go-to" size for root passes and fill passes on pipe and plate.

Seamless Fit and Function

Don't let poor-quality consumables compromise your welds. This nozzle is manufactured to precise tolerances to ensure it screws on smoothly and stays tight during operation. It fits standard setups using 10N30, 10N31, or 10N32 collet bodies. It is not designed for use with gas lenses (which require 54N series cups), making it the correct choice for standard torch configurations. Keep a few 10N47 cups in your shop to ensure you are always ready to lay down perfect beads.
