KP2019-3B1 - Lincoln Electric KP2019-3B1 #6 Alumina Gas Lens Cup (3/8 in)

Industrial Grade TIG Consumable: Lincoln Electric KP2019-3B1

The Lincoln Electric KP2019-3B1 is a premium Alumina Gas Lens Nozzle designed to meet the rigorous demands of industrial TIG welding environments. Classified as a No. 6 cup with a 3/8-inch (9.5 mm) orifice, this component is engineered to work in conjunction with gas lens collet bodies to deliver superior shielding gas performance. Unlike standard nozzles which can produce turbulent gas flow, this gas lens nozzle facilitates a laminar flow pattern. This technical advantage is critical in high-precision industries such as aerospace, petrochemical, and food and beverage manufacturing where weld integrity and atmospheric contamination are primary concerns.

Manufactured from high-quality alumina ceramic, the KP2019-3B1 offers exceptional thermal stability and electrical insulation. The material is selected for its ability to withstand the intense radiant heat generated during the GTAW process without fracturing or degrading rapidly. This durability translates to reduced downtime for consumable replacement and lower long-term operational costs for fabrication shops. The nozzle is specifically threaded to fit securely onto Lincoln Electric gas lens assemblies used with PTA-9, PTA-20, and PTW-25 series torches, ensuring a gas-tight seal that prevents atmospheric aspiration.

For procurement and MRO specialists, stocking the KP2019-3B1 ensures that welding operators have access to versatile consumables. The No. 6 size is an excellent intermediate choice, providing adequate coverage for medium-amperage applications while remaining compact enough for general fabrication tasks. By utilizing gas lens technology, facilities can often reduce post-weld cleaning times due to the improved shielding quality, thereby enhancing overall process efficiency. This product represents Lincoln Electric's commitment to quality and performance in the welding consumables market.

Integration of this nozzle into your welding supply inventory guarantees compatibility with standard Lincoln TIG setups. It is an essential component for operations requiring high-quality root passes or welding on reactive metals like stainless steel and titanium, where gas coverage is paramount. The KP2019-3B1 is a testament to precision engineering, designed to optimize the TIG welding arc and puddle control.
