Analysis of the reasons for the ultrasonic welding machine to burn the insurance

The ultrasonic welding machine will burn the fuse when it is turned on, which means that the ultrasonic generator will burn the fuse as soon as it is turned on, and the fuse will be burned repeatedly.

The ultrasonic welding machine burns the fuse as soon as the power is turned on. Fault 1:

Mainly check the power circuit of the ultrasonic generator, including the fuse circuit, the 450V1000uF large electrolytic capacitor, and the rectifier bridge. You can use an open circuit to determine the fault range, which is to disconnect the DC output.

The ultrasonic welding machine burns the fuse as soon as the power is turned on. Fault 2:

There is no problem with the boot, but the fuse is burned at the beginning of the ultrasonic test, which means that the ultrasonic oscillation circuit is heavily loaded, and the output current exceeds the maximum current value of the fuse. Most of the cases are caused by the damage of the ultrasonic transducer and the damage of the ultrasonic mold. This situation is often accompanied by damage to the power board, and the load needs to be disconnected, and the power amplifier board needs to be repaired and then powered on for testing.
