KP2017-3B1 - Lincoln Electric #6 Alumina TIG Cup for PTA-9/20 Torches

High-Performance Alumina Ceramic Nozzle for Precision TIG Welding

The Lincoln Electric KP2017-3B1 Alumina Nozzle is a critical consumable designed for the professional welder utilizing the Pro-Torch™ TIG series. Specifically engineered for the PTA-9, PTA-20, and PTW-20 torch bodies, this nozzle ensures seamless compatibility and performance. The nozzle features a No. 6 orifice, corresponding to a 3/8-inch (9.5 mm) bore diameter, which is a versatile size suitable for a wide range of amperage settings and joint configurations. By directing the shielding gas flow in a laminar column around the tungsten electrode and the weld pool, this nozzle minimizes atmospheric contamination and oxidation, resulting in cleaner, higher-quality welds.

Manufactured from high-grade alumina ceramic, the KP2017-3B1 exhibits excellent thermal shock resistance and dielectric strength. This material choice allows the nozzle to withstand the intense heat generated during the Gas Tungsten Arc Welding (GTAW) process without fracturing or degrading rapidly. The ceramic composition also resists the adhesion of weld spatter, although TIG welding typically produces minimal spatter, ensuring the nozzle remains clean and unobstructed for longer periods. This specific part number corresponds to the industry-standard 13N series form factor, making it a reliable replacement for standard collet body setups.

In industrial MRO environments, maintaining a stock of genuine Lincoln Electric consumables is essential for minimizing downtime. The KP2017-3B1 is manufactured to precise tolerances, ensuring a secure thread engagement with the collet body. This tight seal is vital for preventing gas turbulence and air aspiration that can lead to porosity in the weld metal. Whether used in aerospace, automotive, or general fabrication, this alumina nozzle provides the consistency required for critical welding applications.
