0559351031 - ESAB PT-36 Shield Cap 200A H35 for Thin Plate

Precision Engineered for High-Amperage Plasma Cutting

The ESAB 0559351031 Shield Cap is a critical component for industrial mechanized plasma cutting systems, specifically designed for the PT-36 torch series. Engineered to handle a current of 200 Amperes, this shield cap is optimized for use with H35 plasma gas—a mixture of 35% Hydrogen and 65% Argon. This specific gas blend is typically utilized for high-speed, high-quality cutting of non-ferrous metals such as stainless steel and aluminum. The shield cap plays a vital role in directing the shield gas flow around the plasma arc, constricting it for energy density while simultaneously protecting the inner nozzle from molten spatter and double-arcing.

Manufactured to tight tolerances, the 0559351031 ensures concentricity between the electrode, nozzle, and shield, which is paramount for maintaining cut angularity and edge quality. This particular model is designated for material thicknesses of less than 1 inch (< 25.4mm), indicating its internal geometry is tuned to provide the optimal standoff and gas dynamics for thinner to medium-gauge plates within the 200A power envelope. Using the correct shield cap for the specific plate thickness and amperage is essential for preventing consumable burnout and achieving dross-free cuts.

Constructed from high-grade tellurium copper or similar conductive alloys, this OEM part offers excellent thermal conductivity, rapidly dissipating the intense heat generated by the H35 plasma arc. This thermal management extends the life of the consumable stack and ensures consistent performance during long production runs on gantry cutting machines.
