KP2017-6B1 - Lincoln Electric No. 10 Alumina TIG Nozzle (5/8") for 9/20 Series Torches

Technical Overview of Lincoln Electric KP2017-6B1

The Lincoln Electric KP2017-6B1 is a professional-grade Alumina Nozzle designed to meet the rigorous demands of industrial Gas Tungsten Arc Welding (GTAW). This specific nozzle is sized as a No. 10, featuring a 5/8-inch (16 mm) orifice diameter. It is engineered to fit the Lincoln Electric Pro-Torch™ TIG models, specifically the air-cooled PTA-9 and the water-cooled PTW-20, as well as other industry-standard Series 9 and Series 20 torch bodies.

Manufactured from high-purity alumina ceramic, this nozzle offers exceptional resistance to thermal shock and high temperatures, ensuring structural integrity even during prolonged welding cycles at higher amperages. The larger orifice size of the No. 10 cup is particularly advantageous for applications requiring a broader shield of inert gas, such as when welding reactive metals like titanium or when a longer tungsten stick-out is necessary to reach into tight corners or fillets.

Proper gas coverage is critical for preventing atmospheric contamination and porosity in the weld pool. The KP2017-6B1 ensures a laminar flow of shielding gas when used with compatible collet bodies. Its threaded base allows for quick and secure replacement, minimizing downtime in production environments. This component is an essential consumable for fabricators requiring precision and reliability in their TIG welding setup.
