The device is a portal mechanical structure with accessories that move along the rails. Thermal/plasma cutting machines under numerical control system (CNC) control are designed for the graphic cutting of ferrous and non-ferrous metal plates by plasma cutting. The thermal/plasma cutter consists of a CNC program control system, a gate drive system, a torch drive system, an electrical control cabinet, a gas distribution system, and a Hypertherm plasma source kit. The wiring of the gas hose and the electrical control line to the cutting machine is carried out through a flexible cable layer.
