22028 - ESAB PT-19 Plasma Torch Nozzle Base 400A (Pack of 5)

Technical Overview of the ESAB 22028 Nozzle Base

The ESAB 22028 Nozzle Base is a critical consumable component engineered specifically for the PT-19 plasma cutting torch series. Designed to facilitate the high-performance demands of heavy industrial cutting, this nozzle base serves as the foundational interface between the torch head and the cutting nozzle. It is rated to handle substantial electrical currents, supporting operations up to 400 Amps, which is characteristic of the heavy-duty capabilities of the PT-19 system. The component plays a vital role in the 2-piece nozzle assembly configuration, ensuring precise alignment and secure seating of the nozzle tip.

Manufactured to ESAB's rigorous OEM standards, the 22028 base is constructed from high-grade conductive materials that optimize electrical transfer while managing the intense thermal loads generated during the plasma arc process. Proper functioning of the nozzle base is essential for maintaining the concentricity of the plasma arc; a worn or damaged base can lead to poor cut quality, irregular bevels, and premature failure of downstream consumables. This pack contains five units, allowing maintenance teams to keep critical spares on hand for immediate replacement during scheduled service intervals or unexpected failures.

In the context of the PT-19's gas dynamics, the nozzle base also assists in the correct distribution of plasma gas and shield gas flows. By maintaining the structural integrity of the torch's front end, it prevents gas leakage and ensures that the cooling mechanisms of the torch function as intended. This is particularly important in mechanized cutting environments where consistency and repeatability are paramount. The 22028 is a direct replacement part, ensuring seamless integration with existing PT-19 setups without the need for modification.
