OVERVIEW

Reliable 10N45 Alumina Nozzles for TIG Welding

Optimize your TIG welding setup with our high-quality generic 10N45 Alumina Nozzles. Designed to fit the industry-standard 3-series torches—specifically the 17, 18, and 26 models—these nozzles are an essential consumable for any fabrication shop or hobbyist welder. The #10 size features a generous 5/8-inch (approximately 16mm) orifice, which provides excellent shielding gas coverage over the weld pool. This larger diameter is particularly beneficial when welding materials that require extensive gas protection to prevent atmospheric contamination, such as stainless steel or titanium, or when walking the cup on larger pipe joints.

Manufactured from premium alumina ceramic, these cups are engineered to withstand high temperatures and thermal shock. Unlike lower-grade materials, alumina maintains its structural integrity even under the intense heat of AC aluminum welding or heavy-duty DC applications. The material also offers good resistance to impact and splatter adhesion, making post-weld cleanup easier and extending the lifespan of the consumable. These nozzles thread securely onto standard collet bodies, ensuring a tight seal that prevents gas turbulence and promotes a stable arc.

This pack of 10 nozzles ensures you have plenty of spares on hand, minimizing downtime during critical projects. Whether you are performing precision work in the aerospace industry or general repairs in an automotive shop, these 10N45 cups deliver consistent performance. They are fully interchangeable with parts from major brands like Weldcraft, Miller, and CK Worldwide, offering a versatile and economical solution for maintaining your TIG torch.

Key Benefits

  • Universal Fit: Seamlessly fits all air-cooled 17/26 and water-cooled 18 series TIG torches.
  • Superior Heat Resistance: Alumina ceramic construction handles high amperage applications without cracking.
  • Optimal Gas Coverage: The 5/8" opening ensures a wide blanket of argon, reducing porosity and oxidation.
  • Economical Choice: High-value generic replacement that meets or exceeds OEM specifications.

FAQ

The 10N45 nozzle fits all 17, 18, and 26 series TIG torches, including air-cooled and water-cooled models from brands like Weldcraft, Miller, Lincoln, and CK Worldwide.

A #10 cup has an orifice diameter of 5/8 of an inch (approximately 16mm). The number represents the size in 1/16th inch increments (10/16 = 5/8).

Yes, it is made of high-grade alumina ceramic, which provides excellent heat resistance and durability for TIG welding applications.

No, the 10N45 is designed for standard collet bodies. If you are using a gas lens, you would typically need a 54N series nozzle (for medium gas lenses) or 53N series (for large gas lenses).

These nozzles are sold in a package of 10.

A larger cup like the #10 provides a wider umbrella of shielding gas, which is beneficial for welding reactive metals like stainless steel or titanium, and allows for greater tungsten stick-out.

No, the 9 and 20 series torches use the 2-series consumables (13N nozzles). The 10N45 is strictly for the larger 3-series torches (17, 18, 26).

This is a high-quality generic replacement part manufactured to meet or exceed OEM specifications for fit and performance.
