1. Turn on the power switch and the indicator light is on.
2. Turn on the power switch of the generator, the power indicator light is on, the output fault indicator light is slightly on, and the power adjustment knob is placed at the minimum position.
3. If the output fault indicator light is on for some reason during use, resulting in overcurrent protection, it is necessary to shut down the ultrasonic spot welder, turn the power adjustment knob counterclockwise, and turn it down before starting the machine.
4. It is not allowed to turn on the generator for a long time when the transducer is empty, otherwise it is easy to generate heat and damage the transducer.
5. During normal welding, clamp the parts to be welded on the welding fixture, turn on the switch and carry out one-time welding.
6. Adjust the "welding time" knob to increase the welding time clockwise and decrease it counterclockwise.
7. Power, time and pressure are three important factors for the welding system. Workpieces of different specifications require different power. Time and pressure need to be adjusted repeatedly to achieve the best process specification.

8. After use, cut off the ultrasonic spot welder power switch.
