• First Indicator Light (Green):
  • Constant light: Power is normal.
  • Breathing: The machine has entered manual hibernation mode and is slowly reducing to room temperature.
• Second Indicator Light (Red): Illuminates when the setting temperature is 300°C.
• Third Indicator Light (Red): Illuminates when the setting temperature is 350°C.
• Fourth Indicator Light (Red): Illuminates when the setting temperature is 400°C.
• General Indicator Behavior:
  • Always on: Warming/cooling process is complete.
  • Flashing: The iron is currently warming up or cooling down to the set temperature.

6.3 PID Precise Temperature Control

The GD301 utilizes PID (Proportional-Integral-Derivative) control for stable and accurate temperature maintenance, making it suitable for both simple soldering and precision repairs.

7. Maintenance

• Tip Cleaning: Regularly clean the soldering tip with a damp sponge or brass wool to remove oxidation and solder residue. A clean tip ensures better heat transfer and longer tip life.
• Tip Tinning: After cleaning and before storage, always tin the tip with a small amount of solder to prevent oxidation.
• Storage: Ensure the soldering iron is completely cool before storing it in a dry place.
• Inspection: Periodically inspect the power cable and the iron for any signs of damage.

8. Troubleshooting

• Iron not heating:
  • Check if the power supply is properly connected and functioning.
  • Ensure the power supply meets the 9-24V requirement.
  • Verify the soldering tip is correctly installed.
• Poor solder joints:
  • Clean and re-tin the soldering tip.
  • Increase the set temperature if necessary.
  • Ensure the components and PCB pads are clean.
• Temperature unstable:
  • Ensure the power supply is stable and provides sufficient current.
  • Check for any loose connections.

10. User Tips

• The GD301 heats up very quickly, often in just a few seconds, even when powered by a compatible power bank, making it highly convenient for portable use.
• For optimal performance, especially during continuous or heavy-duty soldering, consider using a power supply with a higher current capacity within the specified voltage range.
• If your kit includes multiple soldering tips, ensure each tip fits securely into the iron before use.
