KP2030-5B1 - Lincoln Electric 1/8" TIG Collet for 9/20 Series Torches

Genuine Lincoln Electric TIG Torch Consumable

The Lincoln Electric KP2030-5B1 is a high-precision collet designed for use with 1/8 inch (3.2 mm) tungsten electrodes. As a critical component in the TIG welding assembly, this collet ensures the electrode is held firmly in place within the torch head, facilitating the necessary electrical contact required for stable arc initiation and maintenance. Manufactured to Lincoln Electric's rigorous standards, this part is engineered to withstand the thermal cycles inherent in Gas Tungsten Arc Welding (GTAW) while maintaining its dimensional integrity.

This specific collet is compatible with a wide range of air-cooled and water-cooled torches, specifically the Lincoln PRO-TORCH™ PTA-9 and PTA-20 models, as well as the PTW-20 water-cooled torch. Its design follows the industry-standard form factor (often cross-referenced as 13N24), making it also suitable for use with generic WP-9, WP-20, and WP-25 series torches. The component is machined from high-grade copper alloy, chosen for its superior electrical conductivity and heat dissipation properties, which helps prevent overheating and extends the service life of both the collet and the collet body.

Proper selection of consumables is vital for inventory management and operational efficiency. The KP2030-5B1 is supplied as a single unit (indicated by the B1 suffix in some cataloging systems, though often sold in bulk packs depending on the distributor). It is designed to mate perfectly with the corresponding collet body and back cap, creating a sealed gas path that protects the weld pool. Industrial supply managers should ensure this SKU is stocked for fabrication teams utilizing 300-series amperage ranges or standard precision TIG setups requiring 1/8" electrodes.

Replacing collets at regular intervals is recommended to prevent arc wandering caused by poor electrical contact or physical deformation. A worn collet can twist or fuse to the tungsten, leading to downtime. By utilizing genuine Lincoln Electric parts like the KP2030-5B1, facilities ensure equipment reliability and consistency in weld quality across production lines.
