The Hypertherm 220637 is a heavy-duty outer retaining component and beveled shield cap engineered for HyPerformance HPR series automated plasma cutting systems. It serves as a sacrificial and protective barrier for internal consumables while managing gas flow dynamics in high-amperage mechanized environments.
Features
Vented Shield Design: Directs secondary gas flow to cool internal consumables and the nozzle.
Conical Flow™ Technology: Increases arc energy density for cutting speed and quality.
Shield Protection: Protects the nozzle from molten metal blowback during piercing operations.
Stack-up Precision: Engineered to maintain alignment tolerances for the five-part consumable stack (Electrode, Swirl Ring, Nozzle, Retaining Cap, Shield).
Swirl Action: Contributes to the swirling action of the plasma gas in specific configurations.
Synergistic Design: Consumable geometry is matched to system power supply features to optimize service life.
