0558005137 - ESAB PT-19 Plasma Nozzle 300A 2.0mm

Precision Engineering for Heavy Industrial Cutting

The ESAB 0558005137 Nozzle is a critical component designed for the PT-19 plasma cutting torch system. Engineered to handle high-amperage applications, this nozzle is rated for 300 Amps, making it suitable for heavy-plate fabrication and industrial scrapping operations. The nozzle features a precision-bored 2.0mm (0.078 inch) orifice which plays a vital role in constricting the plasma arc, increasing its energy density and velocity to achieve clean, dross-free cuts on thick materials.

Manufactured from high-conductivity copper alloy, this component is designed to efficiently dissipate the extreme thermal loads generated during 300A operation. Proper heat management is essential to prevent orifice erosion and extend the service life of the consumable. The geometry of the nozzle is strictly controlled to ensure optimal gas flow dynamics, stabilizing the arc and protecting the electrode. As an OEM part, it guarantees correct alignment within the torch head, preventing gas leakage and ensuring the safety and reliability of your plasma cutting equipment.

Regular inspection and replacement of the nozzle are necessary to maintain cut quality. A worn or ovalized orifice can lead to beveled cuts, reduced cutting speeds, and increased dross. This genuine ESAB replacement ensures that your PT-19 system continues to operate at peak performance parameters.
