- Page 5 Drop Buffer Adjusting Screw: Adjust the drop buffer rate of the welding head (at the point 24mm from the end of the drop stroke). Rotate it clockwise to increase the buffer rate or rotate it anti-clockwise to decrease the buffer rate. Vibrating Cylinder: Accommodate and secure the oscillator and spacer to connect the welding head.
- Page 6 14. Welding timer: The time during which the ultrasonic wave is transmitting. 15. Curing Timer: The time from stopping the ultrasonic transmission to when the vibrating cylinder rises. During this time, the plastic is curing from its molten state with the pressure being exerted on the work-piece.

- Page 13 III. Operation Guidelines: (1) Notes: 1. During operation, do not open the door of the electrical box to avoid high-voltage injury. 2. Carry out adequate grounding to avoid electrostatic charge. 3. During operation, both hands should be placed around the button and keep away from the welding head to avoid injury.
- Page 14 ※ 6. Before operation, always check the sonic wave to ensure the resonance between the vibration system and oscillator, especially after the welding head is replaced or the amplitude is changed. (5) Mold Adjustment Procedure To acquire the largest throughput, the distance between the welding head and the work-piece should be as short as possible, but a sufficient space is required for the placement and removal of the work-piece.
