5.2. Welding Procedure

Follow these steps for effective spot welding:

1. Select Mode: Use the controls to select either Automatic or Manual mode based on your preference.
2. Adjust Parameters: Set the desired gear (power level), preheat time, and trigger time (delay) according to the thickness of the nickel sheet and the material being welded. Experiment with lower settings first.
3. Position Welding Pins: Place both welding pins firmly onto the nickel strip, ensuring good contact with the battery terminal underneath. The recommended welding angle is 45°-60° to the welding surface for optimal results.
4. Initiate Weld:
   • Automatic Mode: The weld will automatically trigger after the set delay once both pins make proper contact.
   • Manual Mode: Press the welding button located on the side of the device to initiate the weld.
5. Inspect Weld: After each weld, visually inspect the connection to ensure it is strong and secure.
