A method and device for electrically connecting enameled wire ends with contact surfaces. The enameled wire is stripped and pressed against the contact surface. The wire is charged with at least one of an electromagnetic and an acoustical energy. The enamel layer of the wire end is destroyed with the first energy in a first step. This is accomplished by charging the region with at least one of a first electromagnetic energy and a first acoustical energy. The enamel layer of the wire end is only partially destroyed in the first step through the pressing of a region of the wire end against the contact surface with a first pressing force. The wire is permanently connected to the contact surface with a second energy in a further step. The same region of the wire is pressed against the contact surface with a second, lower pressing force in the subsequent process step. It is charged with a second energy and connected to the contact surface so as to conduct electricity.
