0559210113 - ESAB PT-36 400A WMS Plasma Electrode

Technical Overview of the ESAB 400A WMS Electrode

The ESAB 0559210113 is a specialized high-amperage electrode engineered for the Water Mist Secondary (WMS) plasma cutting process. Designed primarily for use with the ESAB PT-36 automated plasma torch, this component is rated for operation at 400 Amperes. The WMS process is distinct in its utilization of Nitrogen as the plasma gas and ordinary tap water as the secondary shield. This combination allows for a high-energy density arc that significantly improves cut speeds and edge quality on non-ferrous materials such as stainless steel and aluminum.

Constructed to withstand the extreme thermal loads of 400A cutting, this electrode features a robust conductive body and a high-performance insert material tailored for Nitrogen plasma environments. The geometry of the electrode is precision-machined to ensure concentricity with the nozzle, which is vital for maintaining arc focus and preventing double-arcing during high-power operation. In the WMS process, the water shield vaporizes to create a hydrogen-rich atmosphere around the arc, reducing oxidation on the cut face; the electrode plays a pivotal role in sustaining the stable arc root required for this chemical interaction.

Industrial MRO professionals and automated cutting system operators rely on genuine ESAB consumables to maintain the tight tolerances required in heavy fabrication. The 0559210113 electrode is manufactured to strict OEM specifications, ensuring consistent electrical conductivity and thermal dissipation. Proper maintenance of the electrode, including regular inspection of the pit depth, is essential for preventing torch damage and ensuring the longevity of the entire consumable stack in continuous production environments.

By utilizing this specific 400A WMS electrode, facilities can leverage the full capabilities of their m3 Plasma systems, achieving dross-free cuts and reducing secondary processing operations. It represents a critical node in the high-precision thermal cutting workflow.
