1. Turn on the voltage of the ultrasonic plastic welding machine and maintain a certain air pressure.

2. Use special tools to remove the original welding die on the equipment and install the ultrasonic die for the products to be welded (loose clockwise, remember to tighten it). Here, pay attention to tighten the screws of the die first. Make sure that the contact surface between the screw of the ultrasonic mold and the horn of the machine is clean and tidy. If necessary, grind it with fine sandpaper.

3. Turn on the power supply of the ultrasonic welding machine, turn on the start button, wait for five seconds, turn off the power supply, and then press the acoustic detection button on the controller to hear the ultrasonic from the ultrasonic welding machine (the sound should be crisp, without hoarseness and excess noise). If the sound is hoarse or screaming, it is necessary to check whether the ultrasonic mold is broken or loose, and take countermeasures.

4. Loosen the two fastening handles behind the boot rack, and swing the machine head up to a certain height according to the height of the product.

5. Turn off the air source and keep the equipment in a static state without power. (adjust the air pressure controller to "zero")

6. Place the products to be welded on the ultrasonic bottom mold and ensure mold clamping.

7. Pull down the whole mold vibration cylinder, make the upper mold close to the bottom mold, shake the head lifter, press the upper mold onto the product, and keep the product consistent with the upper and lower molds.

8. Increase the air pressure to 0.1MPa, turn the selector switch to manual, press two green start buttons to lower the ultrasonic mold and press the product.

9. Shake the lifter to keep the limit screw at a distance of 1mm from the vibration cylinder.

10. Tighten the frame fastening handle, fix the bottom mold, and press the red emergency stop button to raise the machine head.

11. Select the automatic switch fluctuation, adjust the welding parameters and time of the product, and arrange the production.
