PURPOSE:To prevent a wire from being damaged and cut without excessive magnetostrictive vibration at the time of deceleration of wiring speed by dropping excitation voltage lower than that at the time of acceleration when wiring speed of a wiring machine is at deceleration and also the wiring is not an end. CONSTITUTION:An excitation circuit 8 for generating excitation voltage for magnetostrictively vibrating a stylus 10 according to an output of a V-F conversion circuit 7 is connected to the circuit 7, while the stylus 10 for performing magnetostrictive vibration by excitation voltage and melting an adhesive layer is attached to the excitation circuit 8. When wiring speed is at deceleration and also the wire is not an end, an output from a sawtooth wave generation circuit 1 is input not via an analog switch A3 but via a resistance attenuator 2 and an analog switch B4 to the V-F conversion circuit 7. DC voltage of a reduced value is input to the V-F conversion circuit 7. The stylus 10 performs magnetostrictive vibration according to the reduced excitation voltage. |
