KP2016-3B1 - Lincoln Electric #7 Alumina TIG Cup for PTA-9/20 Torches

Industrial Grade TIG Consumables

The Lincoln Electric KP2016-3B1 Alumina Nozzle No 7 is a critical consumable designed for precision Gas Tungsten Arc Welding (GTAW). Engineered to meet the rigorous demands of industrial fabrication environments, this nozzle is manufactured from high-purity alumina ceramic. This material selection is paramount for ensuring longevity and performance, as alumina offers exceptional resistance to high temperatures and thermal shock. In production settings where torches undergo rapid heating and cooling cycles, the structural integrity of the nozzle is essential to prevent cracking and downtime.

This specific nozzle features a #7 orifice, measuring 7/16 of an inch (approximately 11 mm) in diameter. This size is widely regarded as a standard for general-purpose welding, providing a balanced shield of inert gas that protects the weld pool from atmospheric contamination without consuming excessive gas. It is specifically calibrated to fit Lincoln Electric's PTA-9 and PTA-20 series torches, as well as other industry-standard torches with similar front-end configurations (often referred to as the 9/20 series). The precision threading ensures a tight mechanical seal against the collet body, preventing gas leakage that could lead to porosity in the weld.

For procurement and inventory managers, the KP2016-3B1 represents a reliable OEM replacement part that ensures compatibility and consistency across welding stations. Using genuine Lincoln Electric consumables helps maintain the validity of equipment warranties and ensures that the welding parameters remain stable. The nozzle's design facilitates laminar gas flow, which is critical for achieving X-ray quality welds in industries such as aerospace, petrochemical, and automotive manufacturing. Its durability reduces the frequency of replacement, thereby optimizing operational costs and maintaining continuous workflow efficiency.

Whether utilized in manual welding operations or automated setups, this alumina nozzle delivers the consistency required for high-quality metal joining. It is an essential stock item for any facility utilizing Lincoln Electric TIG equipment for light to medium-duty applications.
