KP2033-2B1 - Lincoln Electric .040" Gas Lens for 9/20 Series TIG Torches

Precision Gas Lens for Industrial TIG Applications

The Lincoln Electric KP2033-2B1 Gas Lens is a critical consumable designed to enhance the performance of Gas Tungsten Arc Welding (GTAW) operations. Engineered specifically for use with .040-inch (1.0 mm) tungsten electrodes, this component replaces the standard collet body in compatible TIG torches. It is manufactured to precise tolerances to ensure seamless integration with Lincoln Electric's PTA-9, PTA-20, and PTW-20 torch series, as well as other industry-standard Series 9 and Series 20 torches.

The primary function of this gas lens is to transform the turbulent flow of shielding gas from the torch into a coherent, laminar stream. This is achieved through a multi-layer stainless steel mesh screen integrated into the brass body. By rectifying the gas flow, the lens ensures a more stable and effective shield around the molten weld pool, significantly reducing the risk of atmospheric contamination such as porosity or oxidation. This is particularly vital in industries requiring high-purity welds, such as aerospace, food and beverage processing, and petrochemical piping.

From an operational standpoint, the KP2033-2B1 allows for a greater electrode stick-out—often up to an inch or more depending on conditions—without compromising shield integrity. This feature provides welders with better access to restricted joints and deep grooves where standard nozzles would fail to provide adequate coverage. The component is built for durability and consistent performance, making it a reliable choice for MRO environments and high-production fabrication shops.

Installation is straightforward, requiring a compatible gas lens nozzle (cup) to accommodate the wider diameter of the lens body. This part is essential for fabricators looking to optimize their TIG setups for thinner gauge materials where .040" tungsten is utilized, ensuring that the arc remains focused and the heat affected zone is minimized.
