A wire stripper of the type wherein an electrically heated blade rotates about the wire to melt a circle of insulation so that an end piece of insulation can be pulled off. A circuit for energizing the device operates for a preset time at a predetermined current, to assure melting of insulation to the required depth without damaging the central conductor and to minimize the time of the operation. A blade support extends along a side of the blade opposite the side that contacts the wire, to support the blade against deflection, and to help confine heat to the blade. The blade is an easily replacable element whose opposite end extends through apertures in a pair of spaced pins, and current is carried to the pins by a pair of slip rings and a pair of flexible wires that extend in helixes about the shaft from the slip rings to the pins.
