45V41 - Weldcraft 45V41 Gas Lens for 9/20 Series Torches (.020") - 2 Pack

Genuine Weldcraft 45V41 Gas Lens for Precision TIG Welding

The Weldcraft 45V41 Gas Lens is a premium TIG torch consumable designed to enhance the performance of your welding setup. Sold in a convenient package of two, these gas lenses are engineered specifically for use with 0.020-inch (0.5 mm) tungsten electrodes. They are compatible with the popular 9 Series (air-cooled) and 20 Series (water-cooled) TIG torches, including models WP-9, WP-20, A-125, and W-250. By replacing a standard collet body with this gas lens, operators can achieve significantly better gas coverage and weld quality.

Gas lenses are an essential upgrade for welders looking to improve their results on critical joints. The primary function of the 45V41 is to transform the turbulent flow of shielding gas into a laminar flow. This is achieved through a multi-layer mesh screen inside the lens that straightens the gas stream as it exits the nozzle. The result is a coherent column of gas that protects the molten weld pool more effectively from atmospheric contamination, even at slightly longer stick-out distances.

Using a gas lens like the 45V41 allows the welder to extend the tungsten electrode further past the cup without sacrificing shielding integrity. This extended stick-out provides superior visibility of the arc and the puddle, which is particularly beneficial when welding in tight corners, fillets, or obstructed areas. Additionally, the improved efficiency of the gas coverage can sometimes allow for a reduction in gas flow rates, saving on consumable costs over time.

These genuine Weldcraft parts are manufactured to strict tolerances, ensuring a perfect thread fit into your torch body and optimal electrical conductivity. Whether you are working on delicate aerospace components, thin-gauge stainless steel, or precision instrumentation, the 45V41 gas lens provides the stability and control needed for high-quality TIG welding.
