Abstract
A setting tool for driving fastening elements into a substrate comprises a holder for holding a fastening element; a drive-in element for transferring a fastening element held in the holder into the substrate along a setting axis; and, a drive for driving the drive-in element toward the fastening element along the setting axis, wherein the drive comprises an electrical capacitor; a squirrel-cage rotor arranged on the drive-in element; and, an excitation coil, which during rapid discharge of the capacitor is flowed through by current and generates a magnetic field that accelerates the drive-in element toward the fastening element, and wherein the setting tool has a control unit, which is suitable for carrying out a fuse discharge of the capacitor during which current does not flow through the excitation coil.
