Key Components:
- Main Unit: Houses the control circuitry, battery, and display.
- Spot Welding Pens: Connected via flexible cables, these pens deliver the welding current to the workpiece. The pins are removable and replaceable.
- Foot Pedal Switch: Activates the welding process, allowing for precise positioning of the pens.
- Power Adjustment Knob: Controls the output power from 1 to 9 levels (0-800A).
- Digital Display: Shows the internal battery voltage in real-time.
- Charging Interface: For connecting the power adapter to recharge the internal battery.
5. Setup
- Initial Charge: Before first use, fully charge the spot welder. Connect the power adapter to the charging interface on the unit and plug it into a suitable power outlet. The digital display will show the battery voltage. Charge until the voltage stabilizes at its maximum level.
- Connect Components: Ensure the spot welding pens are securely connected to the main unit. Connect the foot pedal switch to its designated port.
- Work Area Preparation: Set up your work area on a stable, non-flammable surface. Ensure adequate lighting and ventilation. Keep all necessary materials (nickel strips, batteries, etc.) within reach.

6. Operating Instructions
6.1 Power On/Off
The device typically powers on automatically when the knob is turned from the 'OFF' position. To power off, turn the knob fully counter-clockwise to the 'OFF' position.
6.2 Adjusting Welding Power
The spot welder features a 1-9 level knob adjustment for output power, ranging from 0-800A. Turn the knob clockwise to increase the output power. A higher setting is generally required for thicker nickel strips or stronger welds. Start with a lower setting and gradually increase as needed for your specific material.

6.3 Welding Process
- Prepare Workpiece: Ensure the nickel strip and battery terminals (or other materials) are clean and free of oxidation.
- Position Pens: Place the two spot welding pens firmly onto the nickel strip, ensuring good contact with the material to be welded. The pens should be positioned close together but not touching each other.
- Initiate Weld: While maintaining firm pressure on the pens, press and hold the foot pedal switch.
- Observe Indicator: The red light on the unit will blink three times quickly, indicating the welding cycle is in progress. After approximately 0.5 seconds, the unit will output a current to complete the weld.
- Release Pedal: Release the foot pedal switch once the weld is complete.
- Inspect Weld: Carefully inspect the welded joint for strength and appearance. Adjust the power setting if the weld is too weak or if it burns through the material.

Tip for Beginners: The battery voltage level displayed on the LCD screen is crucial. Ensure the voltage is above 7.3V for optimal welding performance. If it drops below this, recharge the unit.
7. Maintenance
- Cleaning: Regularly clean the welding pens and the main unit with a dry, soft cloth. Ensure no metal dust or debris accumulates on the welding tips.
- Welding Pen Tips: The tips of the welding pens are consumable. If they become worn or pitted, they can be removed and replaced to maintain optimal welding performance.
- Storage: Store the spot welder in a cool, dry place away from direct sunlight and moisture. Ensure the unit is powered off before storage.
- Battery Care: To prolong battery life, avoid completely discharging the unit. Recharge when the voltage display indicates a low level (below 7.3V).
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Weak or inconsistent welds | Low battery voltage, insufficient power setting, poor contact with workpiece, dirty welding tips. | Recharge the unit (if voltage is below 7.3V). Increase power setting. Ensure firm and clean contact. Clean or replace welding tips. |
| Unit does not power on | Battery fully discharged, power knob in 'OFF' position. | Connect to charger. Turn power knob clockwise to an active setting. |
| Welds burn through material | Power setting too high. | Decrease the power setting using the adjustment knob. |
| Foot pedal unresponsive | Foot pedal not properly connected, faulty pedal. | Check foot pedal connection. If issue persists, contact support. |
