45V44 - Weldcraft 45V44 TIG Gas Lens 3/32" (2-Pack)

Optimize TIG Shielding with Weldcraft Precision

The Weldcraft 45V44 Gas Lens is a critical upgrade for professional TIG welders seeking superior shielding gas coverage and improved weld quality. Designed to replace standard collet bodies in 9, 20, 22, 24, and 25 series TIG torches, this component utilizes a multi-layer mesh screen to rectify the flow of shielding gas. By transforming the typically turbulent gas stream into a coherent, laminar column, the gas lens ensures that the weld pool remains protected from atmospheric contamination even under challenging conditions.

One of the most significant technical benefits of the 45V44 is the ability to extend the tungsten electrode stick-out. In standard setups, extending the tungsten too far results in the dissipation of the shielding gas envelope, leading to porosity and oxidation. With the laminar flow provided by this gas lens, operators can extend the tungsten up to an inch or more (depending on cup size) while maintaining a stable protective atmosphere. This feature is indispensable when welding in deep corners, fillets, or restricted spaces where nozzle obstruction typically hinders visibility.

Manufactured from high-grade copper and brass, the 45V44 is engineered to withstand the thermal cycling and electrical demands of TIG welding. It is sized specifically for 3/32-inch (2.4mm) tungsten electrodes, a common size for medium-amperage applications ranging from 125A to 250A. Whether utilizing an air-cooled WP-9 or a water-cooled WP-20, this genuine Weldcraft component ensures precise fitment and optimal electrical conductivity. This package contains two gas lenses, ensuring you have a spare on hand for critical projects.

Implementing gas lenses into your welding procedure specification (WPS) can lead to tangible improvements in weld aesthetics and structural integrity. The reduction in turbulence not only saves gas in some configurations but also produces a cleaner, shinier bead profile on sensitive materials like stainless steel and titanium. Trust in the reliability of Miller Weldcraft components to maintain the high standards required for industrial fabrication.
