The Lincoln Electric KP2017-2B1 Alumina Nozzle No. 5 is a critical consumable designed for professional TIG welding applications. Engineered to fit Lincoln's Pro-Torch™ series—specifically the PTA-9, PTA-20, and PTW-20 models—this nozzle ensures reliable performance in demanding industrial environments. The nozzle features a 5/16-inch (8 mm) orifice, designated as a #5 size, which is ideal for general-purpose welding where a focused column of shielding gas is required to protect the weld pool from atmospheric contamination.
Manufactured from high-grade alumina ceramic, this nozzle offers exceptional resistance to high temperatures and thermal shock. Unlike lower-quality ceramics that may crack under the stress of rapid heating and cooling cycles, the KP2017-2B1 is built to withstand the rigors of continuous operation. Its durability reduces downtime associated with frequent consumable replacement, making it a cost-effective choice for fabrication shops and manufacturing facilities.
Proper gas coverage is essential for achieving defect-free welds in materials like stainless steel and aluminum. The precision-molded interior of this Lincoln Electric nozzle promotes laminar gas flow, minimizing turbulence that can lead to porosity. Whether you are performing intricate root passes or cosmetic cover passes, this #5 alumina cup provides the consistency needed for high-quality results. It installs easily onto standard collet bodies, ensuring a tight seal and proper alignment with the tungsten electrode.
