Genuine Hypertherm HyPerformance (HPR) nozzle assembly for 260 A mechanised plasma cutting of thick plate mild steel, using oxygen as the plasma gas and air as the shield gas. The nozzle constricts the high-current plasma arc through a precision orifice to deliver a narrow, high-energy cutting jet with square edges and low dross. Replace it when the orifice is worn or damaged. Use with the matching 260 A electrode and shield.
