摘要：
When starting a wire cutting operation, a first predetermined current is supplied from a power unit to a wire, and at the same time predetermined tension is applied from a tension applying device to the wire. When a first predetermined time elapses since the start of the wire cutting operation, the current supplied from the power unit is switched to a second predetermined current which is smaller than the first predetermined current, and also the predetermined tension is continuously applied, whereby the wire is cut.
