0559211711 - ESAB 800A Aluminum Plasma Shield Cap H35/N2

Precision Engineered for Heavy Industrial Plasma

The ESAB Shield Cap 800A Al H35 N2 (Part Number: 0559211711) is a specialized consumable component designed for high-performance mechanized plasma cutting systems. Engineered by ESAB, a global leader in welding and cutting technologies, this shield cap is built to withstand the extreme thermal and physical stresses associated with cutting at amperages as high as 800A. It is specifically calibrated for applications involving Aluminum workpieces where H35 (35% Hydrogen / 65% Argon) or N2 (Nitrogen) are utilized as plasma or shield gases. In the realm of industrial MRO and fabrication, using genuine OEM parts like this shield cap is critical for maintaining the tight tolerances required for automated cutting machinery.

The primary function of this shield cap is to protect the inner nozzle and electrode from molten metal spatter (dross) and the intense radiant heat generated during the cutting process. By maintaining a clean and undamaged front-end assembly, the shield cap ensures consistent arc starting and stability. Furthermore, it plays a vital role in directing the flow of the secondary shield gas. This gas curtain not only cools the nozzle but also assists in constricting the plasma arc, leading to higher energy density and cleaner cuts. For facilities processing thick aluminum plates, the specific geometry of this cap helps mitigate the formation of dross and improves the angularity of the cut edge.

Compatibility is key in mechanized systems such as the ESAB m3 Plasma series. This component is manufactured to exact specifications to ensure a perfect seal and electrical isolation where necessary. Improperly fitted or generic alternatives can lead to gas leaks, double-arcing, and premature torch failure. By investing in the authentic ESAB 0559211711 Shield Cap, operators ensure their equipment runs at peak efficiency, reducing downtime associated with consumable changes and troubleshooting. This part represents the intersection of durability and precision, essential for heavy-duty industrial environments.

Whether you are operating a gantry cutting table or a robotic cell, the condition of your torch consumables directly impacts your productivity. This 800A shield cap is robust enough to handle long duty cycles, making it an ideal choice for shipyards, heavy equipment manufacturing, and structural aluminum fabrication. Ensure your inventory is stocked with the correct consumables to keep your production lines moving without interruption.
