KP4141-4 - Lincoln Electric LC105 40A Plasma Nozzle (5-Pack)

Precision 40A Plasma Cutting Nozzle for LC105 Torches

The Lincoln Electric KP4141-4 is a specialized 40-amp nozzle designed for the LC105 plasma torch platform, primarily utilized with the Tomahawk 1500 plasma cutting system. This consumable is critical for defining the shape and intensity of the plasma arc, constricting the gas flow to create a high-velocity, high-temperature stream capable of severing conductive metals with precision. Manufactured to Lincoln Electric's exacting tolerances, these nozzles ensure optimal electrical and thermal conductivity, which is essential for maintaining arc stability during operation.

In plasma cutting, the nozzle orifice diameter is directly correlated to the amperage setting. The KP4141-4 is engineered specifically for 40-amp output, making it the ideal choice for thinner gauge materials where a narrower kerf and lower heat input are required. Using the correct nozzle amperage rating prevents premature orifice erosion and ensures the arc remains focused. This results in cleaner cuts with reduced dross accumulation on materials such as mild steel, stainless steel, aluminum, brass, and copper. The nozzle also plays a vital role in the cooling of the electrode and the shielding of internal torch components from molten spatter.

These nozzles are suitable for both standard cutting and gouging applications within the 40A range. Regular inspection and replacement of the nozzle are necessary to maintain cut quality; a damaged or widened orifice can lead to beveled cuts, loss of arc, or damage to the torch head. This package contains five (5) genuine Lincoln Electric nozzles, providing operators with necessary spares to maintain continuous production in industrial environments ranging from automotive repair to general fabrication.
