KP2033-1B1 - Lincoln Electric .020" Gas Lens Collet Body for 9/20 Series Torches

Precision Gas Coverage for Micro-TIG Applications

The Lincoln Electric KP2033-1B1 Gas Lens is a specialized TIG welding consumable designed for the most delicate and precise welding tasks. Sized specifically for .020 inch (0.5 mm) tungsten electrodes, this gas lens is an essential upgrade for welders working with extremely thin gauge materials, electronics, or medical components where arc stability and gas purity are paramount.

Unlike standard collet bodies which can create turbulent gas flow, this gas lens utilizes a multi-layer mesh screen to organize the shielding gas into a coherent, laminar column. This laminar flow provides a much stiffer and more reliable shield around the weld pool, significantly reducing the risk of atmospheric contamination (porosity) even if the torch angle varies slightly or if there are minor drafts in the workshop.

Enhanced Visibility and Access

One of the standout benefits of switching to the KP2033-1B1 gas lens is the ability to increase tungsten stick-out. Because the gas column remains coherent for a longer distance, you can extend your tungsten further past the ceramic cup—often up to an inch depending on the cup size—without compromising shielding. This is critical when welding in tight corners, inside pipes, or in recessed areas where a standard nozzle would obstruct your view of the arc.

Compatibility and Durability

Manufactured to Lincoln Electric's high standards, this component is machined from durable brass alloy to ensure excellent electrical conductivity and heat resistance. It is designed to fit standard 9-series (air-cooled) and 20-series (water-cooled) TIG torches, including the Lincoln PTA-9, PTA-20, and PTW-20 models. Whether you are a professional fabricator or a hobbyist focusing on precision work, this gas lens improves the consistency and quality of your TIG welds.
