If there is an output greater than 0.5a-1a, it indicates that the ultrasonic generator has generated oscillation current and is working. The reason may be that it is not effectively transmitted to the ultrasonic transducer, such as the open circuit of the connecting wire in the middle. Of course, it is also possible that the interior of the ultrasonic transducer is completely damaged. At this time, the simple way is to test with a transducer that is determined to be normal, and the problem can be distinguished; Of course, if the current is large at this time, greater than 1a and greater than the normal no-load current, it is necessary to focus on the inspection of the transducer, whether there are cracks in the aluminum parts, whether there are cracks in the horn, etc;

After eliminating the above problems, it is necessary to check the output circuit. The output circuit is connected with the ultrasonic transducer and forms a parallel resonant circuit with the ultrasonic transducer. Due to the failure or value change of components in the circuit, it will cause no vibration or weak vibration, which should be completely eliminated;

While paying attention to whether the sound wave output of ultrasonic plastic welding machine is normal, we should also have a good effect in terms of quality. Choosing more reliable equipment will be the basis for ensuring more stable performance. Therefore, we should compare more, so that we can be accepted by more consumers, so that we can be more in place in terms of service, so as to be recognized by more users, so that we can be better in terms of quality.
