The ultrasonic signal generator is composed of an ultrasonic power amplifier module which can convert 50 / 60 Hz power frequency AC to super audio frequency for the transducer and a control module with the functions of "system protection monitoring" and "automatic tuning". The control module can cut off the ultrasonic energy when the ultrasonic welding work fails, so as to provide high safety and reliability for the generator and even the whole set of welding equipment.

The built-in automatic constant amplitude system can automatically compensate for different air pressure changes and voltage fluctuations, and can steplessly adjust the ultrasonic amplitude from 50% to 100%, so as to meet the requirements of different welding workpieces.

Using IGBT as power amplifier, the reaction speed is 100 times faster than that of traditional silicon power transistor, so the protection function is better.
