45V116 - Weldcraft 45V116 Large Diameter Gas Lens 1/16" (2-Pack) for WP-17/18/26

Weldcraft 45V116 Large Diameter Gas Lens Overview

The Weldcraft 45V116 is a premium large diameter gas lens designed for industrial TIG welding applications requiring precision and superior shielding gas coverage. Engineered to fit Series 17, 18, and 26 TIG torches (including WP-17, WP-18, and WP-26 models), this consumable is an essential upgrade for fabricators working with reactive metals or complex joint geometries. This package contains two (2) genuine Weldcraft gas lenses, sized specifically for 1/16-inch (1.6mm) tungsten electrodes.

The primary function of the 45V116 gas lens is to transform the turbulent flow of shielding gas from the torch into a coherent, laminar stream. This is achieved through a multi-layered fine mesh screen integrated into the brass body of the lens. By smoothing out the gas flow, the lens creates a wider and more stable protective envelope around the weld pool. This is particularly critical in industrial environments where drafts or positional welding might otherwise compromise the integrity of the shield, leading to porosity or oxidation.

For MRO and supply chain managers, stocking the 45V116 ensures that welding operators have the necessary components to maintain high-quality standards. The large diameter design differs from standard gas lenses by offering an even broader area of coverage, which is beneficial for materials that require extended post-weld shielding or for walking-the-cup techniques on larger pipes. Compatibility with standard large diameter alumina nozzles (57N series) and appropriate insulators (such as 54N63) is required for proper installation.

Weldcraft, a brand synonymous with TIG welding excellence, manufactures these components to strict tolerances. The brass construction ensures excellent electrical conductivity and heat dissipation, while the stainless steel mesh screens are resistant to corrosion and heat degradation. Using genuine Weldcraft parts like the 45V116 helps maintain the duty cycle and performance ratings of the torch assembly, ensuring reliable operation during extended welding shifts.
