KP2018-2B1 - Lincoln Electric No. 7 Alumina Gas Lens Cup for 9/20 Torches

Premium Alumina Gas Lens Nozzle for Industrial TIG Applications

The Lincoln Electric KP2018-2B1 is a high-performance Alumina Gas Lens Nozzle designed to meet the rigorous demands of industrial TIG welding. Engineered with precision, this No. 7 size nozzle features a 7/16-inch (11 mm) orifice, making it an ideal choice for a wide range of welding applications where consistent gas coverage and weld integrity are paramount. Manufactured from high-grade alumina ceramic, this consumable offers exceptional resistance to thermal shock and high temperatures, ensuring a longer service life even under continuous duty cycles common in manufacturing and fabrication environments.

This nozzle is specifically designed to function as part of a gas lens system. Unlike standard collet bodies that can create turbulent gas flow, a gas lens system utilizes a mesh screen to organize the shielding gas into a laminar column. The KP2018-2B1 directs this coherent stream of gas over the weld pool, significantly reducing the risk of atmospheric contamination, porosity, and oxidation. This is particularly critical when welding reactive metals such as stainless steel, titanium, and aluminum, where shield integrity is directly correlated to mechanical properties and aesthetic finish.

Compatibility is key for maintenance, repair, and operations (MRO) efficiency. The KP2018-2B1 is fully compatible with Lincoln Electric's PTA-9, PTA-20, and PTW-20 series torches, as well as Magnum PRO 9 and 20 models. It serves as a direct replacement for standard industry part number 53N61, allowing for seamless integration into existing inventory systems for standard 9/20 series TIG torches. By utilizing genuine Lincoln Electric consumables, operators ensure that their equipment maintains the tight tolerances required for precision arc control and reliable electrical conductivity.

In addition to its thermal properties, the alumina construction provides a robust barrier against physical impact and spatter adhesion. While TIG welding produces minimal spatter, the ceramic material is easy to clean and resists the buildup of contaminants that could otherwise disturb the gas flow. For facility managers and welding engineers seeking to optimize their TIG processes, the KP2018-2B1 offers a balance of performance, durability, and cost-effectiveness, ensuring that production lines remain active and weld quality remains high.
