6. Operating Instructions
6.1 Understanding the Display
The 1.8-inch TFT screen provides real-time information and allows for parameter adjustments:
- Voltage (V): Current battery voltage.
- Temperature (°C): Internal device temperature.
- Preh (Preheating): Duration of the preheating pulse (in ms).
- Puls (Pulse): Duration of the main welding pulse (in ms).
- Inte (Interval): Delay between pulses (in ms).
- Dots: Number of welding pulses per trigger.
- CUR (Current): Real-time welding current.
- SUM: Total number of welds performed.
6.2 Adjusting Welding Parameters
The SWM-10 allows for custom settings to optimize welding performance:
- Use the navigation buttons (usually up/down arrows or a rotary encoder) to select the parameter you wish to adjust (Preh, Puls, Inte, Dots).
- Press the confirmation button (often a central button or a separate 'SET' button) to enter adjustment mode for the selected parameter.
- Use the navigation buttons to increase or decrease the value.
- Confirm your selection to save the new setting.
- Double Pulse Welding Technology: The device utilizes a double pulse system. The first pulse cleans the oxide layer on the weldment surface, reducing spark spattering. The second pulse ensures consistent energy output for improved welding reliability. Adjusting 'Preh' and 'Puls' fine-tunes this process.
6.3 Performing a Spot Weld
- Prepare Workpiece: Ensure the nickel strip and battery terminals (or other materials) are clean and free of oxidation.
- Position Pens: Place the tips of both welding pens firmly and evenly onto the nickel strip, which should be in contact with the material to be welded. Ensure good contact pressure.
- Initiate Weld: The device will automatically detect contact and initiate the welding process according to the set parameters. A distinct spark and sound will indicate a successful weld.
- Inspect Weld: After welding, carefully inspect the joint for strength and appearance. Adjust parameters as needed for optimal results. The SWM-10 can weld nickel plate, sheet iron, and steel sheet up to 0.25mm thick.
6.4 Power Bank Function
The SWM-10 can also function as a power bank:
- Connect your USB-powered device (e.g., mobile phone) to the USB output port (5V 2.1A) on the SWM-10 using a compatible USB cable.
- The SWM-10 will begin charging the connected device. The screen may display charging status or output parameters.
7. Maintenance
- Cleaning: Regularly clean the welding pen tips to remove any residue or oxidation. Use fine-grit sandpaper or a wire brush if necessary. Keep the main unit clean and free of dust.
- Storage: Store the SWM-10 in a cool, dry place, away from direct sunlight and extreme temperatures.
- Battery Care: For optimal battery life, avoid fully discharging the battery frequently. If storing for extended periods, charge the battery to approximately 50-70%.
- Inspection: Periodically inspect the welding pens and cables for any signs of damage or wear. Replace damaged components immediately.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Poor or inconsistent welds | Incorrect welding parameters; dirty welding tips or workpiece; insufficient pressure; low battery. | Adjust Preh, Puls, Inte, and Dots settings. Clean welding tips and workpiece. Apply firm, even pressure. Recharge the device. |
| Device does not power on | Battery is completely discharged; faulty power button. | Charge the device for at least 30 minutes. If still unresponsive, contact support. |
| Overheating warning on screen | Continuous heavy use; poor ventilation. | Allow the device to cool down. Ensure adequate ventilation around the unit. Reduce welding frequency. |
| Power bank function not working | Low battery on SWM-10; faulty USB cable; connected device not compatible. | Ensure SWM-10 is sufficiently charged. Try a different USB cable. Verify the connected device is standard USB-chargeable. |
9. User Tips
While no specific user reviews or Q&A were provided for this manual, here are some general tips for optimizing your experience with the FNIRSI SWM-10:
- Practice on Scrap Material: Before working on your main project, practice welding on similar scrap materials to fine-tune your settings and technique.
- Consistent Pressure: Apply consistent and firm pressure to the welding pens for reliable and strong welds.
- Cleanliness is Key: Always ensure both the nickel strip and the battery terminals are clean. Any dirt, grease, or oxidation will significantly reduce weld quality.
- Monitor Temperature: Keep an eye on the device's temperature displayed on the screen, especially during prolonged use, to prevent overheating.
- Battery Level: For best performance, ensure the device has a sufficient charge before starting a welding session.
