45V116S - Weldcraft 45V116S Large Stubby Gas Lens 1/16" (2-Pack)

Technical Overview of the Weldcraft 45V116S

The Weldcraft 45V116S is a specialized Large Diameter Stubby Gas Lens designed to enhance the performance of TIG welding operations using 1/16-inch (1.6mm) tungsten electrodes. This component is engineered to fit a wide range of air-cooled and water-cooled torches, specifically the 9, 20, 9P, 9V, 20P, 22, and 25 series. By replacing standard collet bodies with this gas lens, operators can achieve a significantly more stable shielding gas envelope. The internal mesh screens within the lens rectify the flow of inert gas (typically Argon), transforming turbulent flow into a coherent, laminar stream. This reduction in turbulence is critical for preventing atmospheric contamination of the weld pool, particularly on sensitive materials like stainless steel, titanium, and aluminum.

Operational Benefits and Design

One of the primary technical advantages of the 45V116S is its "stubby" configuration. This design shortens the overall length of the torch head assembly, thereby increasing the welder's ability to access confined spaces and complex geometries that would be inaccessible with a standard length setup. Furthermore, the laminar flow generated by the gas lens allows the tungsten electrode to be extended significantly farther—often up to an inch or more depending on conditions—beyond the ceramic cup without compromising shielding coverage. This extended stick-out provides the operator with superior visibility of the arc and the weld puddle, facilitating greater precision. The "Large Diameter" aspect of this specific lens ensures a wider umbrella of shielding gas, which is beneficial for maintaining coverage over the heat-affected zone during cooling.

Compatibility and Specifications

This product is sold in a package of two, ensuring that industrial supply inventories can be maintained with adequate backup components. It is a genuine Weldcraft part, manufactured to strict tolerances to ensure proper electrical conductivity and thermal management within the torch head. It is specifically keyed for 1/16" (1.6mm) diameter electrodes. Users should note that utilizing this stubby gas lens typically requires compatible stubby collets and specific large-diameter alumina nozzles to complete the assembly. The 45V116S is an essential upgrade for fabrication environments requiring high-quality radiographic welds and improved operator ergonomics.
