Plasma is heated to very high temperatures and highly ionized gas cutting machine type, it will arc power will be transferred to the workpiece, the workpiece is melted and high-calorie blown off, forming a plasma arc cutting working condition. Compressed air into the torch assigned by the chamber after two, that the formation of the plasma gas and secondary gas. Plasma arc gases from the molten metal effect, while the auxiliary gas is cooled and the various components of the torch to blow off the molten metal. Cutting power supply consists of two parts of the main circuit and control circuit, electrical principle: The main circuit comprises a contact laser cutting machine, high leakage reactance of the three-phase power transformer, three-phase bridge rectifier, ignition coil and high frequency protection elements and other components. From high leakage reactance lead to steep the external characteristics of the power supply. The control circuit via a push button switch on the torch to complete the entire cutting process: pre-ventilation - the main circuit power supply - frequency arc - cutting - interest arc - stop. Large CNC cutting machine according to the different angles, different materials, choose a different hanger, scribing device configuration, punching and drilling equipment, line cutting torch, plasma torch and the like. Widely used in shipbuilding, pressure vessels, mining machinery, engineering machinery and other industries. High quality frame construction ensures maximum machine rigidity, the gantry structure to eliminate stress annealing machine components, ensure long-term deformation.
