10N49 - Weldcraft 10N49 #5 Alumina TIG Cup (10-Pack)

Reliable Shielding for Precision TIG Welding

When you are under the hood, the last thing you want to worry about is your consumables failing mid-bead. The Weldcraft 10N49 Alumina Nozzle is the industry standard #5 cup for a reason: it works. Designed for the popular 17, 18, and 26 series torches, this cup gives you the consistent gas coverage you need for high-quality TIG welds. Whether you are welding mild steel, stainless, or aluminum, having a fresh, clean nozzle is the first step toward a porosity-free weld. The #5 size (5/16") is perfect for tight spots and detailed work where you need a focused gas column.

Built to Withstand the Heat

TIG welding generates intense heat, and your torch parts take the brunt of it. These nozzles are made from premium alumina ceramic, a material known for its ability to handle rapid temperature changes without cracking. While glass cups look cool for Instagram, alumina is the workhorse of the industry. It stands up to the heat of the arc and resists spatter buildup better than lower-quality ceramics. This means you spend less time scraping spatter out of your cup and more time laying down dimes. The high impact resistance also means that if you accidentally drop your torch, your cup has a fighting chance of surviving.

The Value of Genuine Parts

This 10-pack of genuine Weldcraft nozzles ensures you have plenty of backups in your toolbox. We've all been there—you're in the middle of a critical root pass, and you chip your cup. With a 10-pack on hand, you can swap it out in seconds and get back to work. Genuine Weldcraft parts are manufactured with precision threads, so they screw on smoothly every time without binding or cross-threading. Don't settle for cheap knock-offs that might have uneven orifices or poor concentricity; stick with the brand that defines TIG welding quality.

Application Versatility

The 10N49 fits the most common torches found in fab shops and garages across the country. If you are running a WP-17 air-cooled torch on your portable machine or a WP-18 water-cooled setup on a bench, this cup fits. It pairs perfectly with standard collet bodies and is an essential part of any TIG welder's consumable kit. Keep your gas flow laminar and your welds clean with these durable, high-performance nozzles.
