11GL53 - WP-12 Gas Lens 5/32" (4.0mm) - 11GL53

High-Performance Gas Lens for Heavy-Duty TIG Welding

The 11GL53 Gas Lens is a specialized consumable designed for the WP-12 series of water-cooled TIG torches. Engineered to support high-amperage welding operations up to 500 amps, this component is essential for fabricators working with thick materials and requiring precise arc control. The gas lens is specifically sized to accommodate 5/32-inch (4.0mm) tungsten electrodes, making it a robust solution for heavy industrial applications.

Unlike standard collet bodies which can create turbulent gas flow, the 11GL53 utilizes a multi-layer mesh screen to organize the shielding gas into a coherent, laminar stream. This laminar flow technology provides a much broader and more stable umbrella of protection over the molten weld pool. By effectively displacing atmospheric contaminants such as oxygen and nitrogen, the gas lens significantly reduces the risk of porosity and oxidation, ensuring high-integrity welds on sensitive metals like stainless steel, aluminum, and titanium.

One of the primary technical advantages of installing an 11GL53 gas lens is the ability to extend the tungsten electrode further past the nozzle cup—often up to an inch or more depending on the gas flow rate and cup size. This extended stick-out capability is crucial when welding in deep grooves, tight corners, or complex geometries where standard nozzle configurations would obstruct the welder's view or fail to provide adequate shielding. The component is manufactured from high-grade copper alloys to ensure optimal electrical conductivity and heat dissipation, which is vital when operating at the WP-12's 500-amp limit.

This product is a direct replacement for standard collet bodies in WP-12 setups and integrates seamlessly with standard WP-12 collets and alumina nozzles. It is an indispensable upgrade for automated welding systems and manual welders alike who demand consistency, cleanliness, and superior arc performance in their heavy-duty fabrication processes.
