Ultrasonic spot welding machine's debugging

Ultrasonic spot welding machine debugging:

    1. The portable ultrasonic plastic welding machine has been debugged before leaving the factory. If there is no abnormal situation, turn on the power supply and adjust the welding time to the appropriate position and it can be used directly.

    2. Failure analysis:

    When the system is connected to the power supply, the fuse is blown and the power line is short-circuited. When the power switch is turned on, the power indicator does not light up (1. The power supply is not really connected; 2. The rectifier bridge is broken; 3. The power switch or indicator light is broken; 4. blown fuse ;)

    When the power switch is turned on, the power indicator light is on, but there is no ultrasonic wave (1, the voltage is abnormal; 2, the transducer connection is not in good contact; 3, the micro switch is broken; 4, the transducer is broken; 5, the die head is broken; 6 , The connection of the transducer and the die head is loose; 7. The connectors of the circuit board are in poor contact;)
