Cutting by melting. The steel is cut using plasma. The plasma is generated by an electric arc. The electric charge causes the gas to ionize partially. During this process, the gas passes into plasma with a possible temperature up to 30,000 ° C. The high temperatures cause the steel to melt and parts even sublimate. AWS features 2 HD plasma cutting machines with 1 or 2 torches with cutting thicknesses of up to 20 mm or 50 mm with a 40 meters in length cutting bed.
