Working principle

The ultrasonic generator converts low frequency alternating current into high frequency alternating current and converts electrical energy into mechanical energy of high frequency vibration through the transducer.
When the welding head is ACTS on the contact surface of the thermoplastics, it produces tens of thousands of high-frequency vibrations per second.
High frequency vibration transmits ultrasonic energy to the welding area through the upper welding piece, and the upper and lower welding pieces in this region experience friction and cause local high temperature.
After the ultrasonic action, the pressure takes a few seconds, so that it solidifies and adjusts, forming a solid molecular chain for welding.

Automatic frequency monitoring

When the generator is started with an ultrasonic wave, the appropriate operating frequency point will be found as the starting frequency according to the load characteristics of the converter and the welding head. During the welding process, the generator will constantly monitor the frequency to make sure that the entire system is always operating at the proper frequency point. This is particularly effective for a welding process that can affect the temperature of the welding head, which can cause the resonance frequency to shift.

Constant amplitude control

The PID amplitude control algorithm embedded in the generator can perform closed loop control on the output amplitude signal and adjust adaptive to changes in the external environment and workpiece to ensure the consistency of the amplitude signal output.

10 ~ 100% amplitude adjustable

Different amplitude output can be set for different welding process requirements.

Three welding modes

According to different welding methods, the generator provides three welding modes: external control, time and energy.

LCD local monitoring

The generator can display operating parameters such as ultrasonic frequency, amplitude, power, energy, voltage, current and phase in real time and also adjust related parameters locally.

RS485 remote control

Support MODBUS RTU standard protocol, can communicate directly and PLC or HMI and other industrial control equipment for remote communication, automation control.

Protection function

Provide temperature, current, voltage, phase protection function.
