45V26-AAA - Miller Weldcraft 45V26-AAA 3/32" TIG Gas Lens (2-Pack)

Precision Gas Coverage for High-Quality TIG Welding

The Miller Weldcraft 45V26-AAA Gas Lens is a premium consumable designed to elevate the performance of standard TIG welding setups. Engineered specifically for use with 3/32-inch (2.4 mm) tungsten electrodes, this gas lens replaces the standard collet body in 17, 18, and 26 series TIG torches. This specific "AAA" variant is distinguished by its advanced 7-screen mesh construction. Unlike standard gas lenses that may use fewer screens, the 7-screen design provides exceptional filtration and flow straightening capabilities. This results in a coherent, laminar column of shielding gas that effectively protects the molten weld pool from atmospheric contamination, even in drafty conditions or when longer electrode stick-out is required.

Industrial fabricators and maintenance professionals rely on the 45V26-AAA for applications requiring strict adherence to radiographic quality standards. By smoothing the gas flow, the lens reduces turbulence that often leads to porosity and oxidation in sensitive materials like stainless steel, titanium, and aluminum. The ability to extend the tungsten electrode further past the nozzle cup—often up to an inch or more depending on gas flow rates—grants the operator superior visibility of the arc and puddle. This is particularly advantageous when welding in deep grooves, corners, or complex geometries where a standard nozzle would obstruct the view or fail to provide adequate coverage.

This product is supplied as a package of two, ensuring that operators have a backup on hand to minimize downtime. Proper installation requires the use of compatible gas lens insulators (typically the 54N01) and alumina gas lens nozzles (54N series). Integrating the Miller Weldcraft 45V26-AAA into your welding procedure specification (WPS) ensures consistent gas delivery and helps maintain the integrity of the torch assembly by efficiently dissipating heat.
