The ESAB 0559211710 is a specialized high-amperage shield cap engineered for the PT-36 plasma cutting torch, a core component of ESAB's m3 Plasma systems. This specific consumable is rated for 800 Amperes and is designed exclusively for the Water Mist Secondary (WMS) process. The WMS technology utilizes nitrogen as the plasma gas and ordinary tap water as the shield gas, creating a unique chemical reaction in the plasma stream that significantly improves energy density and cut quality on non-ferrous metals.
In the WMS process, the water in the shield stream divides into hydrogen and oxygen. The hydrogen creates a reducing atmosphere that prevents oxidation on the cut face, while the high energy density allows for faster travel speeds compared to standard H35 cutting. This shield cap is critical in directing that water mist shield flow accurately around the plasma arc, constricting it for precision while simultaneously cooling the nozzle and front-end parts. At 800A, the thermal loads are extreme; therefore, the material composition and geometry of this shield cap are manufactured to strict OEM tolerances to withstand the heat and prevent premature failure.
This component is essential for industrial fabricators cutting thick sections of stainless steel and aluminum who require a premium finish with minimal dross. By using the correct 800A WMS shield cap, operators ensure the stability of the arc and the longevity of the downstream consumables (nozzle and electrode). It serves as the primary mechanical interface between the torch internals and the workpiece environment, providing necessary standoff control and spatter protection.
