6. Operating Instructions
Follow these steps to operate your Awithz SH2 Mini Spot Welding Machine:
- Power On: Press and hold the power button to turn on the device. The large color screen will illuminate.
- Select Mode: The device supports both automatic and manual welding modes. Use the control buttons to select your preferred mode.
- Automatic Mode: The device will automatically detect contact and initiate the welding pulse.
- Manual Mode: You will manually trigger the welding pulse using a button or trigger mechanism.
- Adjust Welding Settings: Use the control buttons to adjust welding parameters such as power level (gear) and preheat settings, if available. Start with lower settings and gradually increase as needed for your material.
- Prepare Materials: Clean the surfaces of the battery and nickel strip to be welded. Use sandpaper if necessary to remove any oxidation.
- Position for Welding: Place the nickel strip firmly against the battery terminal. Position the welding pins squarely on the nickel strip, ensuring good contact with both the strip and the battery terminal underneath.
- Perform Weld:
- In Automatic Mode, the weld will trigger automatically once good contact is made.
- In Manual Mode, press the trigger button to initiate the weld.
- Repeat: Move to the next welding point and repeat the process.
- Power Off: After use, press and hold the power button to turn off the device.
