KP2032-5B1 - Lincoln Electric 1/8" TIG Collet Body for 9/20 Series Torches

Precision TIG Components for Professional Results

The Lincoln Electric KP2032-5B1 Collet Body is a critical consumable designed for precision TIG welding applications. Engineered to accommodate 1/8 inch (3.2 mm) tungsten electrodes, this collet body serves as the primary interface between the torch head and the collet, ensuring secure electrode retention and efficient current transfer. It is manufactured to strict tolerances, providing the stability required for high-quality welds in demanding industrial environments.

This component is specifically compatible with Lincoln Pro-Torch™ models PTA-9, PTW-20, and PTA-25, as well as other industry-standard 9 and 20 series TIG torches. The body is constructed from high-grade copper alloy, which offers excellent thermal and electrical conductivity. This material choice minimizes resistance heating within the torch head, thereby prolonging the life of both the collet and the torch itself. By maintaining a consistent electrical contact with the collet, the KP2032-5B1 helps stabilize the welding arc, which is essential for achieving defect-free welds on materials like stainless steel and aluminum.

In addition to its electrical functions, the collet body plays a role in shielding gas management. It houses the collet and aligns it within the gas cup (nozzle), allowing for a laminar flow of shielding gas around the tungsten and the weld pool. Whether you are using air-cooled or water-cooled setups, relying on genuine Lincoln Electric consumables ensures that your equipment operates at peak performance levels, reducing downtime associated with poor arc starts or component failure.
