Cutting with a carbon electrode is a metal removal process that uses heat generated by a carbon arc. The process employs a carbon/graphite electrode, compressed air, and a standard power source. The clamp resembles MMA clamps but has an additional connection to an air compressor. The tip of the carbon electrode must be sharp and can generate temperatures above 3,000 °C. Carbon electrodes require roughly twice the current compared to metallic electrodes, so the machine’s duty cycle should be monitored to avoid overheating. In general, MMA machines with a capacity below 400 A are not suitable for carbon electrode cutting. The electrode tip should not protrude more than 15 cm from the clamp. Carbon electrodes coated with copper offer greater wear resistance.
