People Also Ask:

What is an ultrasonic generator?

The industrial ultrasonic generator, also known as ultrasonic power supply and ultrasonic power box in the industry, mainly converts the main power into an electrical signal that can match the ultrasonic transducer to drive the ultrasonic transducer to work. The frequency of the ultrasonic welding power supply is generally used as 15KHz,20KHz,30KHz,35KHz, and 40KHz.

How to adjust the ultrasonic generator?

The digital ultrasonic generator has four welding modes: time, energy, grounding, and continuous(while the programmed model has no continuous mode), you can adjust the mode per your application requirements. After you receive the ultrasonic power supply, we will send you the user manual and related instruction videos. If you have any questions, please consult our support team for help.

How can you guarantee we receive a good quality?

We have a serious inspection process for quality control, and each delivered product has a quality inspection certificate.

What is the warranty of the ultrasonic welding generator?

The warranty period is 12 months since the shipping out time.
