4. Safety Information
This module generates high voltage. Improper handling can result in serious injury or death. Adhere to the following safety guidelines:
- Do not touch the output wires or arc during operation.
- Ensure all connections are secure and insulated before applying power.
- Operate the module in a dry environment, away from flammable materials.
- Keep out of reach of children.
- If you are not experienced with high voltage electronics, seek professional assistance for installation.
- Always disconnect power before making or changing connections.
5. Setup
Setting up the high voltage module is straightforward, requiring minimal external components.
Wiring Instructions:
- Identify the input wires: The red wire is for the positive (+) terminal of your DC power source, and the white wire is for the negative (-) terminal.
- Connect the red input wire to the positive terminal of your chosen DC power supply (3.6V, 4.8V, 6V, or 12V).
- Connect the white input wire to the negative terminal of your DC power supply.
- The two thick black wires are the high voltage output terminals. Ensure these are properly insulated and positioned for your intended application, maintaining the specified arc distance.

For practical use, it is recommended to incorporate a switch between the power supply and the module's input to control the high voltage output.
6. Operation
Once the module is correctly wired and secured, operation is simple:
- Ensure all safety precautions are observed.
- Apply the specified DC input voltage (3.6V, 4.8V, 6V, or 12V) to the red (positive) and white (negative) input wires.
- The module will immediately begin to generate high voltage pulse current at its output terminals.
- Observe the arc discharge between the output terminals. The arc distance is approximately 10 mm.
Typical Applications:
This high voltage generator module can be used in various applications, including but not limited to:
- Foggers
- Electric gun salutes
- Gas stoves (for ignition)
- DIY high voltage experiments (with extreme caution)

7. Maintenance
The Walfront High Voltage Transformer Module is designed for durability and requires minimal maintenance. Follow these guidelines to ensure its longevity:
- Keep the module clean and free from dust and debris.
- Store and operate the module in a dry environment to prevent moisture damage.
- Avoid exposing the module to extreme temperatures or direct sunlight for prolonged periods.
- Regularly inspect the wires for any signs of damage or fraying. Replace if necessary.
8. Troubleshooting
If you encounter issues with your high voltage transformer module, consider the following troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| No high voltage output / No arc | Incorrect input voltage Loose or incorrect wiring Faulty power supply Module damage | Verify input voltage matches specifications (3.6V/4.8V/6V/12V DC). Check all wire connections for proper polarity (Red to +, White to -) and tightness. Test your power supply with another device. If all else fails, the module may be damaged and require replacement. |
| Weak or inconsistent arc | Insufficient input current Poor connections Environmental factors (humidity) | Ensure your power supply can deliver sufficient current (1000 mA). Re-check all connections for good contact. Operate in a dry environment. |
| Module overheating | Prolonged continuous operation Over-voltage input | Allow the module to cool down between uses. This module is typically designed for intermittent operation. Verify input voltage is within the specified range. |
