KP2033-4B1 - Lincoln Electric 3/32" Gas Lens for 9/20 Series Torches

Precision Gas Shielding for Critical TIG Applications

The Lincoln Electric KP2033-4B1 Gas Lens is a premium consumable designed to enhance the performance of Gas Tungsten Arc Welding (GTAW) operations. Engineered specifically for use with 3/32-inch (2.4 mm) tungsten electrodes, this gas lens replaces standard collet bodies in 9 and 20 series TIG torches. The primary function of this component is to transform the turbulent flow of shielding gas into a coherent, laminar stream. By utilizing a multi-layer fine mesh screen, the gas lens distributes argon evenly around the tungsten and the weld pool.

In industrial environments where weld quality is paramount, such as aerospace, motorsports, or sanitary piping, the stability of the shielding gas is critical. Turbulence caused by standard collet bodies can draw atmospheric contaminants into the weld pool, leading to porosity or oxidation. The KP2033-4B1 mitigates this risk by creating a column of gas that remains stable even at greater distances from the nozzle. This allows the operator to extend the tungsten electrode significantly further than with standard setups, providing the necessary reach for complex geometries while maintaining a pristine inert atmosphere.

Manufactured to Lincoln Electric's exacting standards, this component ensures consistent electrical conductivity and thermal management. It is compatible with a wide range of air-cooled and water-cooled torches, including the PTA-9, PTA-20, and PTW-20 models. Integrating this gas lens into your welding setup is a cost-effective method to immediately improve weld aesthetics and metallurgical integrity.
