5. 사용 설명서
5.1 Spot Welding Function
The 788H offers precise control over welding parameters for various materials, primarily nickel strips for battery pack assembly.
- 전원 켜기: Flip the 'POWER' switch to the ON position. The display will illuminate.
- 용접 모드를 선택하십시오: Ensure the 'WELDING / CHARGE' switch is set to 'WELDING'.
- 현재 설정: 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.
- 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.
- 재료 준비: Clean the surfaces to be welded. Place the nickel strip over the battery terminal or other material.
- Position Electrodes: Carefully position the welding pins onto the nickel strip, ensuring both pins make firm contact with the strip and the underlying material.
- 용접 시작: Press the foot pedal to initiate the weld. The unit will deliver the set pulse(s).
- 용접 검사: 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 배터리 충전 기능
The 788H can also function as an adjustable battery charger.
- 충전 모드 선택: Flip the 'WELDING / CHARGE' switch to 'CHARGE'.
- 배터리 연결: Use the provided charging wires to connect the battery to the 'CHARGE' terminals (red for positive, black for negative).
- 볼륨 설정tage: Use the 'VOLTAGE' knob to set the desired charging voltage (4.2V - 36V). Ensure this matches the battery's nominal voltage.
- 현재 설정: 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.
