KP2030-6B1 - Lincoln Electric 5/32 Inch TIG Collet for PTA-9/20 Torches

Precision TIG Collet for Industrial Applications

The Lincoln Electric KP2030-6B1 is a high-performance collet designed to accommodate 5/32-inch (4.0 mm) tungsten electrodes. Engineered specifically for the Lincoln Electric PTA-9, PTA-20, and PTW-20 series TIG torches, this component plays a critical role in the electrical transfer system of your welding setup. By securely gripping the tungsten electrode, the collet ensures consistent current flow from the torch body to the arc, which is essential for maintaining weld quality in demanding industrial environments.

Manufactured from high-grade copper alloy, this collet offers excellent thermal and electrical conductivity. Its precise machining guarantees concentricity, preventing the tungsten from slipping or becoming misaligned during operation. This is particularly important when working with larger diameter electrodes like 5/32" where heat generation is higher. Proper collet fitment reduces electrical resistance at the contact points, minimizing heat buildup within the torch head and prolonging the lifespan of both the consumable and the torch itself.

For maintenance and repair operations (MRO), using genuine OEM parts like the KP2030-6B1 ensures compatibility and reliability. Generic substitutes often lack the tight tolerances required for optimal gas coverage and arc stability. This collet integrates seamlessly with standard collet bodies and gas lenses used in the 9 and 20 series torch platforms, making it a versatile addition to any professional welder's inventory.
