45V24 - Weldcraft 45V24 TIG Gas Lens Collet Body .040" (2-Pack)

Precision Gas Shielding for TIG Applications

The Weldcraft 45V24 Gas Lens is a critical consumable for professional TIG welders seeking superior shielding gas coverage and improved weld quality. Designed specifically for use with .040-inch (1.0mm) tungsten electrodes, this component replaces the standard collet body in 17, 18, and 26 series TIG torches. Unlike standard collet bodies which can create turbulent gas flow, the 45V24 utilizes a multi-layered fine mesh screen. This screen acts as a diffuser, straightening the flow of argon (or other shielding gases) into a coherent, laminar column. This reduction in turbulence is essential for maintaining a pure weld pool, particularly when working with reactive metals or in drafty shop environments.

Enhanced Visibility and Access

One of the primary technical advantages of switching to the Weldcraft 45V24 Gas Lens is the ability to extend the tungsten electrode further beyond the nozzle cup without compromising shielding integrity. In standard setups, extending the tungsten too far results in the gas column dissipating before it reaches the weld pool, leading to porosity and oxidation. With the laminar flow provided by this gas lens, operators can extend the tungsten significantly further—often up to an inch depending on the cup size—allowing for exceptional visibility of the arc and puddle. This feature is indispensable when welding inside corners, deep grooves, or complex pipe geometries where the torch nozzle would otherwise obstruct the welder's view.

Compatibility and Durability

Manufactured to Weldcraft's rigorous standards, the 45V24 ensures a precise fit with industry-standard WP-17 (air-cooled), WP-18 (water-cooled), and WP-26 (air-cooled) torch bodies. It is designed to work in conjunction with 54N-series gas lens nozzles (cups) and standard .040" collets. The brass body construction offers excellent conductivity and heat resistance, ensuring consistent current transfer to the collet and tungsten. Supplied in a convenient package of two, these gas lenses are an essential stock item for any fabrication shop focused on high-quality GTAW processes.
