Ultrasonic Spot Welding Machine Manual

Product Parameters

Preparation Phase:

Connect the output cable plug of the transducer (amplifier) of the ultrasonic spot welding machine to the generator, and the connection is reliable;

Confirm that the titanium alloy die head of the transducer is not in direct contact with the stainless steel of the bottom plate of the bracket;

Connect the ultrasonic spot welding machine to the 220V/50Hz three-core power supply, and a green indicator light will be on on the instrument control panel, indicating that the instrument is powered on and can be operated.

Warning: Make sure the transducer is well connected and turn on the power button before use. Note that opening the circuit without connecting the transducer is likely to damage the circuit, and instrument damage due to customer mishandling is not covered by the warranty.

Steps for Usage:

1. Frequency adjustment

The fine-tuning frequency knob on the panel can adjust the frequency; it has been adjusted before leaving the factory.

WARNING: Customer self-adjustment or frequent adjustment is not recommended.

If you need to adjust, please follow the steps below:

(1) When the ultrasonic power is turned off;

(2) Confirm that the transducer and the generator are connected reliably and correctly;

(3) Put the transducer into the bracket circular ring with the left hand, adjust the two adjustment fastening screws of the bracket with the right hand, and adjust the stainless steel distance between the end face of the titanium alloy mold and the bracket table according to the thickness of the mask. Generally, the flat mask is 0.1~ 0.15mm (thickness of 1 sheet of A4 paper); KN95 mask is 0.2~0.25mm (thickness of 2 sheets of A4 paper);

Warning: The titanium alloy die head of the transducer must not directly contact the stainless steel, otherwise the ceramic sheet of the transducer will be broken and the die head will be deformed.

(4) Firmly and evenly tighten the two fastening screws, completely fixed, and must not be loose;

(5) Turn on the ultrasonic generator switch;

(6) Slowly turn the knob with the left hand, and slide the right hand on the titanium alloy die head up and down to touch it. The feeling of sliding is the greatest. When there is no screaming, it is the best matching frequency. At this time, the transducer is in the best working state.

2. Power adjustment

Adjust the power knob, observe the working current, and set the appropriate welding power according to the thickness of the welding mask.

Warning: The power is generally 0.15~0.25A at no-load, and the current at load is 0.5~0.8A.

Warning: Overload work is strictly prohibited. In order to protect the machine, transducer and mold, please set the maximum working current reasonably. It is recommended not to exceed 0.4A!

3. Air pressure adjustment

Adjust the cylinder pressure of the upward and downward strokes (decrease clockwise, increase counterclockwise), so that the welding head can touch the welding surface smoothly after stepping on the pedal, and be careful not to cause vibration of the welding surface.

4. Welding time setting

Please set different welding time according to the thickness of the mask. Generally, the time of flat mask is 0.3~0.4S, and the time of N95 is 0.6~0.7S.

Setting Operation:

* Set welding time (in OP mode).

* Enter the setting interface by long pressing the setting button.

* Select the working mode by increasing and decreasing the buttons, and the working mode will flash to prompt.

* Short press the setting button, select the working mode as OP, and enter the parameter setting.

* In the parameter setting interface, short press the setting button to switch the parameter to be modified, and short press/long press the increase/decrease button to modify.

* Short press the pause button to switch the timing unit (1s/0.1s/0.01s/1min).

* After all parameters are set, press and hold the setting button to save the settings and exit.

5. Step on the pedal and start spot welding.

Warning: The operator should be trained to work, skilled and careful to operate the instrument, and the fingers should be 3~5mm away from the welding head during spot welding, and the fingers should not be placed under the titanium alloy head and directly pedal, and do not operate fatigued.
