0558004269 - Esab PT-21AMX 90A Plasma Cutting Nozzle (5-Pack)

Precision 90 Amp Plasma Cutting Nozzle

The Esab 0558004269 Nozzle is a critical consumable component designed for high-performance plasma cutting applications. Engineered specifically for use with the PT-20 and PT-21AMX series torches, this nozzle is rated for 90 Amps of cutting current. In plasma cutting systems, the nozzle plays a vital role in constricting the plasma arc, focusing the energy density to achieve clean, precise cuts on conductive metals. By maintaining tight manufacturing tolerances, Esab ensures that the orifice diameter and geometry are optimized for the specified amperage, resulting in superior cut quality and reduced dross accumulation.

This product is supplied as a package of five, addressing the needs of industrial environments where consumable life is a key factor in operational efficiency. The nozzle is constructed from a high-quality copper alloy, selected for its excellent thermal conductivity and resistance to the intense heat generated during the plasma process. Proper heat dissipation is essential for extending the lifespan of the nozzle and preventing premature failure due to keyholing or orifice erosion. As a genuine OEM part, users can expect consistent performance and seamless compatibility with their existing Esab equipment.

Regular inspection and replacement of the nozzle are necessary to maintain cut quality. A worn or damaged nozzle orifice can lead to a widened arc, reduced cutting speed, and increased bevel angles on the workpiece. The Esab 0558004269 provides the reliability required for demanding fabrication tasks, ensuring that the plasma stream remains focused and stable. This specific nozzle configuration is optimized for 90A output, making it suitable for cutting thicker gauge materials where higher energy input is required.

Technical specifications indicate compatibility strictly with the PT-20 and PT-21AMX torch models. Utilizing incorrect consumables can damage the torch head or result in poor arc initiation. Industrial operators rely on Esab's stringent quality control standards to deliver consumables that perform predictably under load. This 5-pack offering ensures that maintenance teams have the necessary stock on hand to perform quick changeovers, minimizing machine downtime and maintaining production throughput.
