The Lincoln Electric KP2016-6B1 Alumina Nozzle No 4 is a critical component for professional TIG welding setups, designed to deliver precise shielding gas coverage and withstand the rigors of industrial use. Manufactured from high-purity alumina ceramic, this nozzle is engineered to resist high temperatures and thermal shock, ensuring a longer service life compared to standard ceramic cups. It is specifically designed to fit Lincoln Electric Pro-Torch™ TIG models, including the PTA-9 and PTA-20 series, as well as compatible industry-standard torches.
With a 1/4 inch (6.4 mm) orifice, the No. 4 cup is ideal for applications requiring focused gas flow or access to tight corners and confined spaces. Proper gas coverage is essential for preventing atmospheric contamination, porosity, and oxidation in the weld pool. This nozzle directs the shielding gas (typically Argon) directly over the tungsten electrode and the molten puddle, creating a stable environment for high-quality welds on materials such as stainless steel, mild steel, and aluminum.
Industrial fabricators and maintenance professionals rely on genuine Lincoln Electric parts for their consistency and fit. The threaded design allows for quick and secure installation onto the collet body, minimizing downtime during consumable changes. Whether used in aerospace, automotive, or general fabrication, the KP2016-6B1 provides the reliability needed for critical welding tasks.
