This process uses a concentrated electrical arc to burn the material through a high-temperature plasma beam. All conductive materials can be cut. Plasma cutting units with cutting currents from 20 to 160 amperes can cut plates with 0.5 to 50 mm thicknesses. Plasma gas is mainly compressed air. The air plasma arc cutting unit can cut mild, alloy steels, aluminium, copper and other metals and alloys.

• Modern technology for all electrically-conductive materials, used particularly for structural steel, stainless and non-ferrous metals
• Low heat distortion of the material due to densely concentrated plasma arc
• High cutting speeds (5 to 7 times higher than with oxy/fuel cutting) and low dead times (no preheating required)
• Material thickness 0.5 to 50 mm cuttable with plasma current up to 160 amperes
• Efficient cuts in structural steel of up to 30 mm vertically or bevelling
• Highest cutting quality obtainable with fine-beam plasma or water-injection plasma method
