5. Setup

5.1 Charging the Device

Before first use, ensure the spot welder is fully charged.

1. Connect the provided USB Type-C charging cable to the input port on the side of the spot welder (refer to Figure 3.2).
2. Connect the other end of the USB cable to a compatible USB power adapter (4.5V-5.5V, current ≤2.5A).
3. The indicator lights will show the charging status. Charge until the battery is full.

5.2 Connecting the Bonding Wires

Attach the welding pens to the main unit.

1. Insert the connector ends of the two bonding wires into the gold-colored ports on the front of the spot welder.
2. Ensure a secure connection.

6. Operation

6.1 Power On/Off and Level Adjustment

1. Power On: Long press one of the red control buttons on the top surface of the device until the indicator lights activate.
2. Adjust Welding Level: Short press the same red control button to cycle through the available welding power levels. Select the appropriate level for your material. The indicator lights will typically show the selected level.
3. Power Off: Long press the control button again until the indicator lights turn off.

6.2 Spot Welding Procedure

Follow these steps for effective spot welding:

1. Prepare the Workpiece: Ensure the welding object is clean, free of rust or contaminants, and in a flat state.
2. Position the Workpiece: Fix the items to be spot welded securely.
3. Apply Welding Pens: With the device powered on and the desired welding level selected, touch the copper tips of the two bonding wires (welding pens) to the welding object. Ensure both tips make firm and simultaneous contact with the material at the desired welding point.
4. Automatic Welding: The device will automatically output a welding pulse when the soldering pins are connected to the workpiece. The welding process occurs in milliseconds.
5. Cooling Time: After each weld, allow a cooling time of approximately 10 seconds before handling the welded object or performing another weld in the same area.

Note: The device is designed for welding 0.1-0.15mm plates, iron plates, and stainless steel. It is primarily used for welding cylindrical batteries, nickel-hydrogen batteries, and lithium batteries.

7. Maintenance

• Cleaning: Keep the device and welding pens clean and free of debris. Use a dry cloth to wipe the main unit.
• Storage: Store the spot welder in a dry, cool place away from direct sunlight and moisture when not in use.
• Battery Care: For optimal battery life, avoid completely discharging the battery frequently. Recharge the device when the battery level is low.
• Welding Pen Inspection: Regularly inspect the copper tips of the bonding wires for wear or damage. Replace if necessary to ensure good electrical contact.
