54N18 - Weldcraft 54N18 #4 Alumina Gas Lens Cup (10-Pack)

Weldcraft 54N18 Alumina Gas Lens Nozzle #4 (10-Pack)

The Weldcraft 54N18 Alumina Gas Lens Nozzle is a premium consumable designed for professional TIG welding applications. This #4 size nozzle, featuring a 1/4-inch (6.4mm) orifice, is engineered to work specifically with gas lens collet bodies on 17, 18, and 26 series TIG torches. Manufactured from high-grade alumina ceramic, these nozzles offer exceptional resistance to thermal shock and impact, ensuring they hold up under the rigorous conditions of industrial welding environments.

One of the primary advantages of using the 54N18 gas lens nozzle is the improvement in shielding gas coverage. When paired with a gas lens, this nozzle helps produce a laminar flow of argon, which is significantly more stable than the turbulent flow created by standard collet bodies. This stability allows the welder to extend the tungsten electrode further past the cup—often up to an inch or more—without compromising the integrity of the shield. This feature is particularly beneficial when welding in tight corners, deep grooves, or complex geometries where visibility is limited.

The 54N18 is a standard length nozzle that fits seamlessly into existing TIG setups for the popular 17 (air-cooled), 18 (water-cooled), and 26 (air-cooled) torch series. The alumina material not only resists heat but also minimizes the adherence of weld splatter, making post-weld cleanup easier and extending the life of the consumable. This package contains 10 genuine Weldcraft nozzles, ensuring that your shop is well-stocked for continuous production or maintenance tasks.

Whether you are fabricating stainless steel exhaust systems, repairing aluminum components, or performing general mild steel welding, the Weldcraft 54N18 provides the reliability and performance required for high-quality X-ray quality welds. Trust in the durability of genuine Weldcraft parts to maintain consistent arc stability and gas protection.
