0558005218 - ESAB 30-40A Plasma Nozzle for PT-37/38/39 Torches (5-Pack)

Precision Plasma Arc Constriction for Mechanized Systems

The ESAB 0558005218 Nozzle is a critical consumable component designed specifically for the PT-37, PT-38, and PT-39 series of Plasmarc™ mechanized cutting torches. Engineered to operate within the 30 to 40 Amp current range, this nozzle plays a pivotal role in defining the shape and intensity of the plasma arc. In plasma cutting, the nozzle constricts the ionized gas flow, focusing the energy density to achieve clean, precise cuts with minimal dross. Using genuine ESAB nozzles ensures that the orifice geometry is maintained to strict tolerances, which is essential for maintaining cut angularity and edge quality in automated environments.

Manufactured in the United States, these nozzles are built to withstand the intense thermal dynamics of the plasma cutting process. The copper alloy construction provides excellent thermal conductivity, rapidly dissipating heat away from the orifice edge to prolong consumable life. For mechanized setups where consistency is paramount, relying on OEM specifications guarantees that the torch height controls and gas flow parameters remain synchronized with the consumable's performance. Deviations in nozzle bore quality can lead to arc instability, reduced cutting speeds, and increased wear on the electrode.

This package contains five (5) nozzles, allowing operators to maintain a ready supply of replacements for continuous production. Regular inspection of the nozzle orifice is recommended; even minor irregularities or 'keyholing' can significantly impact the quality of the cut part. By utilizing the correct 30-40A nozzle for your specific amperage settings, you optimize the gas velocity and arc focus, resulting in superior performance across compatible ESAB plasma systems.

Whether you are running a PT-37 on a CNC table or utilizing the PT-38/39 configurations, this nozzle ensures that your equipment operates at peak efficiency. It is designed to integrate seamlessly with the torch head assembly, ensuring proper electrical isolation and gas sealing.
