6. Operation

6.1 Spot Welding

1. Prepare Materials: Ensure the surfaces of the materials to be welded (e.g., nickel sheet to battery terminal) are clean and free of oxidation.
2. Position Welding Pens: Hold one welding pen in each hand. Place the tips firmly and simultaneously onto the two points to be welded on the material. Maintain even pressure.
3. Automatic Welding: The device will automatically detect contact and initiate the welding process based on the set preheat, pulse, and interval times. You will hear a distinct welding sound.
4. Inspect Weld: After welding, carefully remove the pens and inspect the weld joint. It should be firm and clean. If the weld is weak or sparks excessively, adjust the settings (see Section 7) or clean the welding tips.

6.2 Power Bank Function

The SWM-10 can also serve as a power bank to charge other devices.

1. Connect Device: Plug your USB-powered device (e.g., smartphone) into the USBA discharging port (7) on the SWM-10 using a compatible USB cable.
2. Charging Indication: The SWM-10 display will show a "Charging" indicator, confirming that power is being supplied to your device.

9. Safety Information

To ensure safe operation and prevent injury or damage, please observe the following precautions:

• Always wear appropriate personal protective equipment (PPE), including safety glasses or a welding helmet, and heat-resistant gloves.
• Operate the device in a well-ventilated area, away from flammable materials and liquids.
• Do not touch the welding tips or the welded material immediately after welding, as they will be extremely hot.
• Keep the device and welding pens dry. Do not operate in wet conditions.
• Ensure the welding pens are properly connected before use. Loose connections can cause arcing or overheating.
• Do not attempt to weld materials thicker than 0.25mm or materials not listed as weldable, as this may damage the device or result in poor welds.
• The SWM-10 features intelligent protection mechanisms: low temperature, high temperature, overcharge, over-discharge, impact resistance, voltage regulation, and short circuit protection. If any warning appears on the screen, cease operation and troubleshoot the issue.
• Keep out of reach of children.

10. Troubleshooting

If you encounter issues with your FNIRSI SWM-10, refer to the following common problems and solutions:

• Poor or Weak Welds:
  • Ensure welding tips are clean and sharp. Replace if worn.
  • Verify sufficient battery charge.
  • Adjust welding parameters (preheat time, pulse time, interval) in the settings menu. Start with lower settings and gradually increase.
  • Ensure firm and even pressure is applied to both welding pens simultaneously.
  • Check that the material thickness is within the 0.1-0.25mm range.
• Device Not Powering On:
  • Ensure the battery is charged. Connect to a power source via the Type-C port.
  • Press and hold the Power/switch button for a few seconds.
  • If unresponsive, try inserting a thin object into the Reset hole (9) to perform a hard reset.
• "Over Temperature" Warning:
  • The device has overheated. Stop operation and allow it to cool down in a well-ventilated area.
  • Avoid continuous, rapid welding cycles.
• "Low Voltage" Warning:
  • The internal battery is low. Recharge the device immediately.
• "Short Circuit" Warning:
  • This indicates a short circuit in the welding circuit. Check the welding pens for damage or exposed wires. Ensure the tips are not touching each other before contacting the workpiece.

11. User Tips

• The SWM-10 is versatile and can be used for welding nickel sheet, iron sheet, stainless steel sheet, and aluminum sheet. Always ensure the material is compatible and within the specified thickness range (0.1-0.25mm).
• The device's operation is controlled via a 4 combination gear adjustment system, allowing for fine-tuning of welding parameters to suit different tasks. Experiment with settings to find the optimal combination for your specific welding needs.
• Utilize the power bank function (5V/2.1A charge and discharge rates) to keep your mobile devices charged on the go, adding extra utility to your spot welder.

12. Maintenance

• Cleaning: Regularly clean the welding tips and the main unit with a dry, soft cloth. Ensure no metal dust or debris accumulates around the welding ports or screen.
• Tip Replacement: Replace worn or damaged welding tips promptly to maintain welding quality.
• Storage: Store the SWM-10 in a cool, dry place, away from direct sunlight and extreme temperatures. Ensure the battery is partially charged (around 50%) for long-term storage.
• Battery Care: Avoid fully discharging the battery frequently. Recharge when the low voltage warning appears.
