KP2033-3B1 - Lincoln Electric 1/16" Gas Lens Collet Body for 9/20 Series Torches

Precision Gas Shielding for High-Quality TIG Welds

The Lincoln Electric KP2033-3B1 Gas Lens is a critical consumable designed to enhance the performance of Gas Tungsten Arc Welding (GTAW) operations. Engineered specifically for 1/16-inch (1.6 mm) tungsten electrodes, this collet body replaces standard collet bodies in compatible torches, such as the PTA-9 and PTW-20 series. The primary function of this component is to transform the turbulent flow of shielding gas from the torch into a coherent, laminar stream. This is achieved through a series of fine stainless steel mesh screens integrated into the brass housing.

By rectifying the gas flow, the KP2033-3B1 provides a wider and more stable umbrella of shielding gas over the weld pool. This stability is paramount when welding reactive materials like titanium, aluminum, or stainless steel, where atmospheric contamination can lead to immediate defects such as porosity or oxidation. Furthermore, the laminar flow characteristics allow the operator to extend the tungsten electrode further beyond the nozzle cup—often up to an inch in draft-free conditions—providing superior visibility of the arc and puddle in tight joints or complex geometries.

Manufactured to Lincoln Electric's rigorous standards, this gas lens ensures consistent electrical conductivity and thermal transfer, helping to keep the collet and tungsten cool during extended welding cycles. It is an essential upgrade for fabricators seeking to improve weld aesthetics and metallurgical integrity.
