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

Achieve Precision Welds with Weldcraft 54N18 Gas Lens Nozzles

When your welding project demands the absolute best in visibility and gas coverage, upgrading to a gas lens setup is the professional's choice, and the Weldcraft 54N18 Alumina Nozzle is the perfect companion for that upgrade. Designed to fit the popular 17, 18, and 26 series TIG torches, this #4 size cup (1/4 inch) is small enough to get you into tight corners and narrow joints where larger cups simply can't fit. Whether you are welding a roll cage, an exhaust manifold, or intricate stainless steel artwork, this nozzle gives you the clearance you need to see the puddle clearly and control the arc with precision.

The magic of this nozzle lies in its compatibility with gas lenses. Standard cups often produce turbulent gas flow, which can pull in oxygen and contaminate your weld if you extend the tungsten too far. The 54N18, when paired with a gas lens collet body, delivers a smooth, laminar column of shielding gas. This allows you to extend your tungsten electrode much further—sometimes up to an inch depending on conditions—giving you unprecedented access to deep crevices without sacrificing shield quality. The result is a cleaner, brighter weld with less oxidation and rework.

Durability is key in any shop environment. Made from premium pink alumina ceramic, these nozzles are built to withstand the intense heat of the TIG arc and the rapid cooling that follows. They resist cracking and chipping better than generic alternatives, meaning you spend less time swapping out broken parts and more time under the hood. This package contains 10 genuine Weldcraft nozzles, ensuring you are stocked up for the long haul. Don't let a cracked cup stop your production; keep your bench loaded with the industry standard for reliability and performance.
