KP2034-6B1 - Lincoln Electric 5/32" Gas Lens for 9/20 Series Torches

Precision Shielding for Heavy TIG Applications

The Lincoln Electric KP2034-6B1 Gas Lens is a premium TIG welding consumable designed to enhance the performance of PTA-9, PTA-20, and PTW-20 series torches. Engineered for 5/32-inch (4.0 mm) tungsten electrodes, this gas lens replaces standard collet bodies to provide superior shielding gas coverage. The core advantage lies in its multi-layered fine mesh screen, which transforms the turbulent gas flow from the torch into a coherent, laminar stream. This reduction in turbulence is critical when welding reactive metals or when operating in drafty shop environments, ensuring the weld pool remains uncontaminated by atmospheric gases.

By stabilizing the gas column, the KP2034-6B1 allows welders to extend the tungsten electrode further past the nozzle cup—often up to an inch depending on the setup—without losing shielding effectiveness. This feature is invaluable for accessing deep corners, fillets, or complex geometries where standard nozzle configurations would obstruct the welder's view or fail to provide adequate coverage. Additionally, the improved efficiency of the gas delivery system can lead to reduced gas consumption rates, offering long-term operational savings for high-volume fabrication shops.

Manufactured to Lincoln Electric's rigorous standards, this component ensures a precise fit with compatible torch bodies and collets. It is an essential upgrade for professionals seeking to maximize weld quality and consistency in demanding TIG applications requiring larger diameter electrodes.
