1. Introduction
This manual provides detailed instructions for the safe and effective operation, setup, and maintenance of your Seesii SE208sd Spot Welder and Heat Gun Kit. This kit is designed for precise spot welding of battery packs and heat shrinking PVC, offering a comprehensive solution for various projects.
2. Safety Information
Always prioritize safety when operating electrical tools. Failure to follow these safety guidelines may result in electric shock, fire, or serious injury.
- Eye Protection: Always wear appropriate eye protection (safety glasses or goggles) when operating the spot welder or heat gun to protect against sparks, molten metal, or hot air.
- Ventilation: Use the spot welder and heat gun in a well-ventilventilated area to avoid inhaling fumes.
- Flammable Materials: Keep flammable materials away from the work area. The heat gun produces high temperatures, and welding creates sparks.
- Electrical Safety: Ensure the power supply matches the tool's requirements. Do not operate with damaged cords or plugs. Avoid contact with live electrical parts.
- Work Surface: Use a stable, non-conductive work surface.
- Children and Bystanders: Keep children and bystanders away from the work area.
- Heat Gun Handling: Do not touch the nozzle of the heat gun during or immediately after use, as it will be extremely hot. Allow the tool to cool completely before storing.
- Spot Welder Probes: Ensure welding probes are clean and properly seated. Avoid short-circuiting the probes.

5. Operating Instructions
5.1. Spot Welder Operation
The spot welder offers both Auto and Pedal modes for flexible operation. Ensure your workpieces (e.g., nickel strip and battery terminals) are clean and properly aligned.

5.1.1. Selecting Operating Mode (Auto/Pedal)
The 2.4-inch LCD screen allows you to select between Auto and Pedal modes. Navigate the menu using the control buttons.
- Auto Mode: For fast, effortless welding. The unit automatically triggers a weld when both probes make contact with the workpiece.
- Pedal Mode: For independent and controlled operation. A weld is triggered only when the foot pedal is pressed, allowing for precise placement.

5.1.2. Adjusting Welding Gear (Power Settings)
The spot welder features 999 gear settings to adjust welding power. This allows for precise control over the weld strength for various materials and thicknesses.
- Use the navigation buttons on the unit to adjust the 'Gear' setting on the LCD screen.
- Start with lower settings and gradually increase until the desired weld strength is achieved.
- The unit can handle nickel-plated 0.5mm, pure nickel 0.3mm, copper 0.15mm, and steel 0.3mm.

5.2. Heat Gun Operation
The 350W mini heat gun is ideal for shrinking PVC heat shrink wrap around battery packs or other applications requiring controlled heat.
- Temperature Settings: The heat gun offers dual temperature settings: LOW (400°F / 200°C) and HIGH (670°F / 350°C). Select the appropriate setting using the switch on the handle.
- Application: Direct the hot air stream evenly over the PVC heat shrink wrap. Move the heat gun continuously to prevent overheating any single spot.

8. Troubleshooting
If you encounter issues, refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Weak or inconsistent welds | Low power setting (Gear), dirty/worn probe tips, poor contact, insufficient charge. | Increase Gear setting. Clean or replace probe tips. Ensure firm contact with workpiece. Recharge the unit. |
| Unit not turning on | No power, unit not charged. | Check power connection. Charge the unit. |
| Heat gun not heating | No power, faulty switch. | Check power connection. Ensure switch is in ON position. |
| Overheating protection activated | Continuous heavy use. | Allow the unit to cool down. Reduce usage intensity. |
