The Electrode is made by Oxygen-free copper as the material in which there is high quality Hafnium embedded, which guarantee the best electrical conductivity and cutting dynamic energy. The Nozzle Shield/ Nozzle Cup is made by Hafnium wire/copper nickel plated, which brings longer life and abrasive resistance. In addition, precision-processed consumables will be combined well with cutting torch and machine. These Torch Consumables are compatible with P80 Plasma Cutting Torch and similar copies; And it is suitable for Plasma Cutting Machine .Materials: Red copper, hafnium, ceramic Nozzle Orifice Size: 1.1mm, 1.3mm, 1.5mm, 1.7mm Electricity: 40A, 60A, 80A, 100A Cutting Thickness: 1-6mm, 6-12mm, 12-20mm, 20-40mm
