KP2843-2 - Lincoln Electric Tomahawk LC40 Standard Plasma Nozzle (5-Pack)

Precision Engineering for the Tomahawk Series

The Lincoln Electric KP2843-2 Standard 40A Nozzle is a critical component designed specifically for the LC40 plasma torch, commonly found on the Tomahawk 625 plasma cutting system. In plasma cutting, the nozzle serves the vital function of constricting the plasma arc, focusing the high-velocity gas stream to generate the intense heat required to melt through conductive metals. This genuine Lincoln Electric consumable is manufactured to tight tolerances, ensuring that the orifice remains perfectly centered and sized to maintain a stable, high-density arc at 40 amps. Using authentic consumables is essential for preserving the fluid dynamics of the plasma gas, which directly correlates to cut angularity, dross accumulation, and overall edge quality.

Material Versatility and Performance

These nozzles are engineered to handle a wide variety of conductive materials, making them a versatile choice for fabrication shops and industrial environments. Whether you are processing mild steel, stainless steel, aluminum, brass, or copper, the KP2843-2 maintains a consistent arc characteristic that allows for clean severance and precision detail work. The copper alloy construction provides excellent thermal conductivity, rapidly dissipating the intense heat generated during the cutting process to prevent premature melting of the nozzle tip. This thermal management is crucial for extending the lifespan of the consumable and protecting the torch head from heat damage.

Maintenance and Replacement

Plasma nozzles are subject to wear over time due to the extreme heat and the erosion caused by the plasma arc. A worn nozzle with an out-of-round orifice can lead to beveled cuts, reduced cutting speed, and arc instability. This package contains five (5) standard 40A nozzles, providing operators with the necessary inventory to maintain continuous operations. Regular inspection of the nozzle orifice is recommended; replacing the nozzle as soon as cut quality begins to degrade ensures that your Tomahawk 625 continues to operate at peak efficiency. By sticking with genuine Lincoln Electric parts, users ensure seamless compatibility and reliability that aftermarket alternatives simply cannot guarantee.
