45V45 - 45V45 TIG Gas Lens 1/8" (3.2mm) for 9 & 20 Series Torches (2-Pack)

Enhance Your TIG Welding Precision

The Generic 45V45 Gas Lens is an essential upgrade for welders looking to improve the performance of their 9, 20, or 25 series TIG torches. Designed to accommodate 1/8-inch (3.2mm) tungsten electrodes, this gas lens replaces the standard collet body to transform how shielding gas is delivered to the weld pool. By utilizing a multi-layered mesh screen, the lens smooths out the gas flow, eliminating the turbulence often associated with standard nozzles. This laminar flow creates a stiffer, more consistent column of gas that protects the molten puddle more effectively from atmospheric contamination.

One of the primary benefits of switching to a gas lens system is the ability to extend the tungsten electrode further beyond the cup. With a standard collet body, sticking the tungsten out too far results in poor shielding and porosity. However, the stable gas stream provided by the 45V45 allows for a significantly longer stick-out (often up to an inch depending on conditions), giving the welder superior visibility of the arc and puddle. This is particularly advantageous when welding in tight corners, inside pipes, or in other confined spaces where the torch nozzle would otherwise obstruct the view.

Constructed from durable copper and brass, these gas lenses are built to withstand the heat and demands of professional welding environments. They are compatible with a wide range of air-cooled and water-cooled torches, including the popular WP-9 and WP-20 models. Whether you are fabricating automotive exhaust systems, aerospace components, or performing general maintenance, the 45V45 gas lens offers a cost-effective way to boost weld quality and consistency.

Key Benefits:

• Superior gas coverage reduces oxidation and porosity.
• Allows for longer tungsten extension for better joint access.
• Compatible with standard 9/20 series consumables (requires compatible insulator).
• Sold as a convenient 2-pack to keep your shop stocked.
