摘要

Device for determining the revolutions of cutting heads (5) during removal of deposits from welding electrodes comprises an electrical and/or magnetic contact-less element (4) arranged on or in the cutting head made from anti-magnetic material. The element passes a sensor (3) which is sensitive for the properties of the element during rotation of the cutting heads. The sensor acquires information about the revolutions of the rotation and the rotating direction of the cutting heads.
