Contact-Arc-Metal-Cutting (shortened CAMC) with a sword like cutting-electrode is a thermal cutting technique currently used for decommissioning of nuclear facilities. A water jetting electrode made up of pure graphite, carbon fibre reinforced graphite or a special tungsten-copper-alloy, melts the metallic workpiece in a cyclic process by resistance heating and a free burning high current spark channel. A Master-Slave-Manipulator leads the electrode through the components, free of tool guiding force.
