KP2030-3B1 - Lincoln Electric 1/16" TIG Collet for 9/20 Series Torches

Precision TIG Welding with Genuine Lincoln Consumables

The Lincoln Electric KP2030-3B1 Collet is a critical component for professional TIG welding applications, designed specifically to hold 1/16-inch (1.6 mm) tungsten electrodes securely within the torch assembly. In the Gas Tungsten Arc Welding (GTAW) process, the collet serves two primary functions: it mechanically grips the electrode to prevent slippage during operation, and it acts as the primary electrical contact point, transferring welding current from the torch body to the tungsten. Because of this dual role, the quality and condition of your collet directly influence arc stability and weld integrity.

Manufactured to Lincoln Electric’s exacting standards, this collet is engineered for compatibility with PTA-9, PTA-20, and PTW-20 series torches, as well as other industry-standard 9 and 20 series models. The component is machined from high-grade copper alloy, chosen for its excellent thermal and electrical conductivity. This ensures that current is transferred efficiently with minimal resistance heating, which prolongs the life of both the collet and the torch head. The precision bore is sized strictly for 1/16-inch electrodes, ensuring a concentric grip that keeps the tungsten centered in the gas cup. A centered electrode is vital for maintaining uniform shielding gas coverage and preventing weld contamination.

Over time, thermal cycling can cause collets to twist, deform, or lose their spring tension, leading to poor arc starts and unstable arcs. Using genuine Lincoln Electric replacements like the KP2030-3B1 ensures that you are restoring your equipment to factory specifications. Whether you are welding thin-gauge stainless steel, aluminum, or mild steel, relying on high-quality consumables helps eliminate variables in the welding process, allowing the operator to focus on technique and puddle control. This collet is an essential stock item for any fabrication shop utilizing air-cooled 9-series or water-cooled 20-series TIG setups.

Investing in genuine OEM parts minimizes downtime associated with equipment troubleshooting. Generic collets often suffer from poor machining tolerances, which can lead to arcing inside the torch body or difficulty in tightening the back cap. The Lincoln KP2030-3B1 guarantees a perfect fit, ensuring your TIG torch operates at peak performance for critical welding tasks.
