The ESAB 0558009550 is a heavy-duty OEM nozzle retaining cup engineered for the mechanized PT-36 Plasmarc torch system. It functions as the primary mechanical clamping component for the front-end consumable stack, compressing the plasma nozzle and gas distributor against the internal torch body. This component establishes and maintains airtight, dual-chamber geometric seals to isolate high-pressure plasma cutting gas from external shielding gas.
Features
Pneumatic Separation Control: Seals torch tip under mechanical compression to ensure unmixed pathways for plasma and shielding gases
Suppression of Double-Arcing: High dielectric resistance eliminates cross-conductive tracking paths
Anti-Deformation Architecture: Resists thermal stress to prevent thread stripping, warping, or stretching
Arc Stability: Ensures exact centering and height alignment of the nozzle for dross-free cuts
