If you encounter issues with your spot welder, refer to the following common problems and solutions:

• Device not turning on: Ensure the battery is charged. Connect the Type-C charging cable and allow it to charge for some time before attempting to power on again.
• Weak or inconsistent welds:
  • Check the battery level; a low battery can affect welding power.
  • Increase the gear (power) setting.
  • Ensure the welding pins are clean and have good contact with the nickel sheet and battery terminal. Sand the tips if necessary.
  • Verify the welding angle (45°-60°) and apply firm, even pressure.
• Overheating: The device has an intelligent internal temperature detection system. If it overheats, it may temporarily shut down. Allow it to cool down before resuming operation.
