Abstract
After the initiation of a first current-supplying time an insulator of a coated wired W,cuts off an electrically conductive path and hence a secondary current I,for melting and removing the insulator is caused to flow from an upper electrode,by way of an intermediate electrode,. An interior conductor is exposed to form an electrically conductive path leading to workpieces (W,and W,) between the upper electrode,and a lower electrode,, allowing a branch current I,to flow into the lower electrode,. A control unit monitors a current detection signal <I,> from a current detecting circuit,. When the signal <I,> has reached a skip level SK, the control unit terminates the supply of current of a first current-supplying time and initiates the current supply of a second current-supplying time for joining the wire W,to a terminal member W,.
