Spot Welding Power Setting:

Start with the first gear and increase the power slowly until it can be welded. Do not increase the power if it can be welded. Avoid MOS bombs. The black solder joints indicate that the power is too high.

When welding, press down the soldering pin lightly, and the nickel sheet and the battery can be bonded together. The harder you press, the less solid the welding will be. It will automatically trigger after pressing down for one second.
