21330 - ESAB 50A Plasma Nozzle for PT-20/21AMX Torches (Pack of 5)

High-Performance 50A Nozzle for Mechanized Plasma Cutting

The ESAB 21330 50 Amp Nozzle is a critical consumable component engineered specifically for the PT-20AM and PT-21AMX Plasmarc™ mechanized cutting torches. In the realm of plasma cutting, the nozzle plays a pivotal role in constricting the plasma arc, focusing the energy density to achieve precise, clean cuts on conductive metals. This specific nozzle is rated for 50 Amperes, making it ideal for medium-duty industrial cutting applications where accuracy and edge quality are paramount.

Manufactured to ESAB's stringent tolerances, this nozzle ensures proper gas flow dynamics and arc alignment. The orifice geometry is precision-drilled to maintain a stable arc column, which is essential for mechanized systems where travel speeds and standoff heights are automated. Using a nozzle with the correct amperage rating is vital; operating a 50A nozzle at significantly higher currents can lead to rapid orifice erosion, while lower currents may result in an unstable arc and poor cut quality.

The PT-20 series torches are workhorses in automated cutting environments. The 21330 nozzle is designed to withstand the intense heat generated during the plasma process, utilizing high-grade copper alloys that offer excellent thermal conductivity. This efficient heat dissipation helps prolong the lifespan of the consumable, reducing downtime associated with frequent changeovers. For maintenance, repair, and operations (MRO) professionals, ensuring a stock of these nozzles is essential for maintaining the operational efficiency of CNC plasma tables and other mechanized setups utilizing the PT-20/21AMX systems.

This package contains five (5) nozzles, providing a cost-effective solution for high-volume production environments. Regular inspection of the nozzle orifice is recommended. As the orifice wears and becomes out-of-round, cut angularity will increase, and dross levels will rise. Replacing the nozzle at the first sign of performance degradation ensures that the mechanized system continues to deliver the high-quality cuts expected from ESAB equipment.
