10N46 Alumina TIG Cup #8 (1/2 Inch) - 10 Pack

Upgrade Your Torch Kit

Every TIG welder knows that a clean, consistent arc starts with the right front-end consumables. This 10-pack of 10N46 Alumina Nozzles gives you the reliability you need to lay down stack-of-dimes welds without worrying about your equipment. The #8 size (1/2-inch opening) is a workhorse in the welding shop, providing a generous umbrella of shielding gas that is perfect for walking the cup on pipe or performing freehand weaves on plate. Whether you are welding stainless steel exhaust systems or structural aluminum, having a fresh nozzle ensures your gas flow remains laminar and your tungsten stays protected.

Built for the Heat

TIG welding generates intense localized heat, and your cup takes the brunt of it. These nozzles are made from durable Alumina ceramic, a material chosen specifically for its ability to resist the thermal shock of starting and stopping arcs repeatedly. They resist splatter buildup better than lower-grade ceramics, meaning you spend less time scraping off spatter and more time welding. If you are "walking the cup," the rim of these nozzles is tough enough to glide along the joint without chipping easily, giving you that smooth, rhythmic motion essential for a consistent bead profile.

Universal Fit for Standard Torches

Don't worry about brand compatibility. If you are running a standard 17, 18, or 26 series torch—whether it's a trusty air-cooled rig in your garage or a water-cooled production torch at work—these cups will screw right on. They are designed to fit standard collet bodies (not gas lenses). This makes them a versatile addition to your welding bag. With 10 in a pack, you can keep a few in your toolbox, a few on your cart, and spares in the cabinet, so you never have to stop mid-project because of a cracked cup.

Why Choose the #8 Cup?

The #8 cup is often considered the "Goldilocks" size for many welders. It offers better gas coverage than a #6, allowing for slightly longer tungsten stick-out to see into tight corners, but it isn't as bulky as a #10 or #12, allowing you to maneuver in restricted spaces. It is an excellent choice for tungsten electrode sizes ranging from 1/16" to 1/8", covering the vast majority of general welding tasks. Grab this pack and ensure your torch is ready for whatever job comes through the door.
