  The ultrasonic welding machine includes an ultrasonic oscillator, an ultrasonic vibrator, a booster, a horn, and a press unit. The ultrasonic oscillator converts an input 50/60 Hz electrical signal into an electrical signal of 20 kHz or 40 kHz. Furthermore, the ultrasonic oscillator amplifies the input voltage (100 V or 200 V) to about 1000 V inside the oscillator. The ultrasonic vibrator generates a stretching motion in the piezoelectric element by repeatedly turning ON / OFF the application of a voltage of 20 kHz or 40 kHz using a characteristic that the thickness changes when a voltage of the piezoelectric element is applied. The booster increases or decreases the amplitude transmitted from the ultrasonic transducer. The horn amplifies or attenuates the ultrasonic vibration transmitted from the booster inside the horn, and transmits the ultrasonic vibration to the object.
