5.1 Spot Welding Function

The 788H offers precise control over welding parameters for various materials, primarily nickel strips for battery pack assembly.

1. Agbara Tan: Flip the 'POWER' switch to the ON position. The display will illuminate.
2. Yan Ipo Alurinmorin: Ensure the 'WELDING / CHARGE' switch is set to 'WELDING'.
3. Ṣètò Ìsinsìnyí: Use the 'SET CURRENT' knob to adjust the welding current. The display shows the current level (e.g., 0-99). Start with lower settings and increase gradually. For 0.1-0.2mm nickel strips, typical settings range from 50-800A.
4. Set Pulse Mode: The unit supports single or dual pulse welding. Adjust the pulse setting based on the material thickness and desired weld strength. Dual pulse is generally recommended for stronger, more consistent welds.
5. Mura Awọn ohun elo: Clean the surfaces to be welded. Place the nickel strip over the battery terminal or other material.
6. Position Electrodes: Carefully position the welding pins onto the nickel strip, ensuring both pins make firm contact with the strip and the underlying material.
7. Bẹ̀rẹ̀ ìṣẹ́po: Press the foot pedal to initiate the weld. The unit will deliver the set pulse(s).
8. Ṣayẹwo Weld: After welding, inspect the joint for strength and appearance. Adjust current and pulse settings as needed. For pure nickel strips, 0.1-0.15mm thickness is typically supported effectively.

5.2 Battery Charging Function

The 788H can also function as an adjustable battery charger.

1. Yan Ipo Gbigba agbara: Flip the 'WELDING / CHARGE' switch to 'CHARGE'.
2. Batiri Sopọ: Use the provided charging wires to connect the battery to the 'CHARGE' terminals (red for positive, black for negative).
3. Ṣeto Voltage: Use the 'VOLTAGE' knob to set the desired charging voltage (4.2V - 36V). Ensure this matches the battery's nominal voltage.
4. Ṣètò Ìsinsìnyí: Use the 'CURRENT' knob to set the desired charging current (0A - 3A). A common charging rate is 0.5C to 1C of the battery's capacity.
5. Abojuto gbigba agbara: Awọn àpapọ yoo fi awọn ti isiyi voltage and current. Monitor the charging process and disconnect the battery once fully charged to prevent overcharging.
