Plasma arc cutting
...free electrons and positive ions. The plasma arc, which can reach temperatures of up to 28,000°C, is transferred to the workpiece, which is usually positive, where it “blows away” the molten metal. Energies of approximately 10kWh m-3 and thermal efficiencies of 85–90% can be achieved. There are three commonly used plasma systems. Manufacture An alternative to flame...
