45V45 - ESAB 45V45 TIG Gas Lens 1/8" (3.2mm) for 9/20 Series Torches

Optimize Your TIG Welding with ESAB 45V45 Gas Lenses

The ESAB 45V45 Gas Lens is a premium TIG welding consumable designed to replace standard collet bodies in 9, 20, 22, 24, and 25 series TIG torches. Engineered for use with 1/8" (3.2mm) tungsten electrodes, this gas lens is an essential upgrade for welders seeking superior shielding gas coverage and improved weld quality. Unlike standard collet bodies that can create turbulent gas flow, the 45V45 utilizes a multi-layer mesh screen to organize the shielding gas into a coherent, laminar column.

This laminar flow technology provides a wider and more stable umbrella of protective gas over the weld pool. By eliminating turbulence, the ESAB gas lens significantly reduces the risk of atmospheric contamination, porosity, and oxidation, particularly when welding sensitive materials like stainless steel, titanium, and aluminum. The consistent gas coverage ensures that the weld zone remains clean and protected, even in drafty conditions or when the torch angle is less than ideal.

One of the primary operational benefits of using the ESAB 45V45 is the ability to extend the tungsten electrode further beyond the cup edge—often up to an inch or more—without losing shielding effectiveness. This extended stick-out capability is invaluable for precision applications, allowing the welder to see past the nozzle and clearly view the arc and weld puddle. It also facilitates welding in deep grooves, corners, and other restricted-access joints where a standard nozzle would obstruct the view or fail to provide adequate coverage.

Manufactured to ESAB's high standards, this gas lens is built from durable brass and copper components, ensuring excellent conductivity and heat resistance. It integrates seamlessly with standard TIG torch setups, requiring only a compatible gas lens nozzle (alumina cup) to complete the assembly. Whether you are a professional fabricator or a serious hobbyist, upgrading to an ESAB gas lens is a cost-effective way to enhance your TIG welding performance.
