Key Components:

• Main Control Board: Houses the primary circuitry, including the microcontroller, power regulation, and relay.
• Digital Display Module: Provides real-time feedback on set time and current parameters.
• Time Adjustment Potentiometer: Used to set the duration of the welding pulse.
• Current Adjustment Potentiometer: Used to set the intensity of the welding current.
• Input/Output Terminals: For connecting power supply, welding transformer, and trigger switch.

4. Setup Instructions

Follow these steps to correctly set up your NY-D01 control board:

1. Power Supply Connection: Connect a suitable AC 9V power supply to the designated input terminals on the control board. Ensure the voltage matches the board's requirements (e.g., AC 9V for the control circuit).
2. Main Power Input: Connect the main AC power (e.g., 110V or 220V, depending on your transformer) to the primary side of your welding transformer. The control board will switch this power.
3. Welding Transformer Output: Connect the primary winding of your spot welding transformer to the output terminals of the control board (typically marked for AC input and output to the transformer).
4. Trigger Switch Connection: Connect a foot pedal or manual trigger switch to the designated trigger input terminals. This switch initiates the welding process.
5. Digital Display Connection: Ensure the digital display module is securely connected to the main board via its ribbon cable.
6. Initial Power-Up: After all connections are verified, apply power to the control board. The digital display should illuminate.

Note: Always double-check all wiring before applying power to prevent damage to the board or connected components. Consult a qualified electrician if you are unsure about any wiring steps.

5. Operating Instructions

The NY-D01 board allows for independent adjustment of welding time and current. The digital display shows the currently set values.

Adjusting Parameters:

• Time Adjustment: Rotate the potentiometer labeled for 'Time' (often marked with 'T' or a clock icon) to increase or decrease the welding duration. The digital display will show the set time in milliseconds (ms) or cycles.
• Current Adjustment: Rotate the potentiometer labeled for 'Current' (often marked with 'C' or an ampere icon) to adjust the welding current intensity. The digital display will show the set current percentage or value.

Welding Process:

1. Place the materials to be welded between the spot welding electrodes.
2. Press the trigger switch (foot pedal or button). The control board will activate the welding transformer for the set time and current.
3. Release the trigger switch after the welding cycle is complete.
4. Inspect the weld for quality and adjust time/current settings as needed for optimal results.

Tip: Start with lower settings and gradually increase them until a strong, consistent weld is achieved for your specific materials.

6. Maintenance

Proper maintenance ensures the longevity and reliable operation of your control board.

• Cleaning: Keep the board free from dust, metal shavings, and debris. Use a soft, dry brush or compressed air for cleaning.
• Connections: Periodically check all wiring connections to ensure they are secure and free from corrosion.
• Storage: When not in use, store the control board in a dry, dust-free environment.
• Inspection: Regularly inspect the board for any signs of damage, such as burnt components or loose connections.
