57N74 - 57N74 Large Diameter Alumina Gas Lens Cup #8 (10-Pack)

Achieve Cleaner Welds with the #8 Large Gas Lens Cup

Take your TIG welding results to the next level with the 57N74 Large Diameter Alumina Gas Lens Nozzle. If you are tired of struggling with porosity, gray welds on stainless steel, or poor visibility in tight corners, switching to a large gas lens setup with this #8 cup is the solution. This nozzle is a favorite among professional fabricators for its ability to provide a wide, calm blanket of shielding gas over the weld puddle. By smoothing out the gas flow, it eliminates the turbulence that often sucks oxygen into the weld, giving you those colorful, shiny beads you strive for.

The #8 size (1/2-inch opening) is the perfect "daily driver" for a wide range of applications. It is large enough to provide excellent coverage on pipe and plate, yet compact enough to maneuver around roll cages or manifolds. Because it is made from high-quality alumina ceramic, it stands up to the intense heat of AC aluminum welding and high-amperage DC work without cracking or melting prematurely. The durability of this cup means you spend less time changing out broken parts and more time under the hood.

One of the biggest advantages of using this 57N74 nozzle with a gas lens is the ability to stick your tungsten out further. Whether you are walking the cup on a root pass or reaching into a tight gusset, the laminar flow keeps your tungsten protected even at extended lengths. This pack of 10 ensures you always have a fresh cup ready to go in your toolbox. Compatible with all major TIG torches including the WP-17, WP-18, and WP-26 series (with large gas lens bodies), this is an essential upgrade for any serious welder looking to improve their consistency and weld quality.
