An automated plasma cutting system is provided that includes a positioning system mounted to a support, an automated plasma arc torch mounted to the positioning system, and at least one power supply operatively connected to the automated plasma arc torch. The power supply may provide electrical power and fluid flow to the automated plasma arc torch for operation. The system further includes a controller in communication with the automated plasma arc torch and the power supply, and an auxiliary plasma arc torch operatively connected to the power supply, wherein the power supply provides electrical power and fluid flow to both the automated plasma arc torch and the auxiliary plasma arc torch. The automated plasma arc torch may process the workpiece to generate a set of features, while the auxiliary plasma arc torch may process/cut a residual framework of the workpiece remaining after formation of the set of features.

A plasma heater includes a plasma heating section, an exhaust wasteheat heating section, a gas circulation pump, a water cooling system, and a treatment tank for waste gas and waste water. Flames emitted by plasma torches of plasma generators are directly sprayed onto first water pipes for heating. Exhaust generated after combustion of the plasma torches flows through the tail gas residual heat heating section in the metal cylindrical casing, then flows out of the metal cylindrical casing to enter the gas circulation pump, and flows back into the plasma generators through the gas circulation pump for recycling. After the circulating exhaust operates for more than 10 minutes, the discharged waste gas and waste liquid enter the recovering treatment tank.

A plasma torch assembly comprises a plurality of plasma torch apertures. Each of these plasma torch apertures is adapted to receive a plasma torch. The plasma torch assembly also comprises a working position for operation of the plasma torchthe working position is pressure sealed for hyperbaric operation of the plasma torch. The plasma torch assembly also has means to move each of the plasma torch apertures to the working position. In this way, plasma torches can be swapped in and out of the working position. A method of operating a plasma torch device comprising such a plasma torch assembly is also described.
