6. Setup

6.1 Charging the Soldering Iron

Before first use, fully charge the soldering iron. Connect the provided Type-C USB cable to the soldering iron's charging port and to a 5V USB power source (e.g., computer, USB adapter, power bank).

• A red light indicates charging.
• A green light indicates charging is complete.

Charging typically takes about 1 hour.

6.2 Installing a Soldering Tip

Ensure the soldering iron is off and cool before changing tips.

1. Gently pull out the existing heating element/tip assembly from the main body.
2. Select the desired soldering tip.
3. Carefully insert the new heating element/tip assembly into the main body until it is securely seated.

7. Operating Instructions

7.1 Power On and Temperature Setting

1. Press and hold the Power/Settings button to turn on the soldering iron. The digital display will illuminate.
2. Use the '+' and '-' buttons to adjust the desired temperature. The iron supports 5-level temperature adjustment within the range of 260℃ - 420℃ (500℉ - 788℉).
3. After setting the temperature, wait approximately 7 seconds for the iron to heat up to the set temperature. The digital display will show the real-time temperature.

7.2 Switching Temperature Units (°C/°F)

To switch between Celsius and Fahrenheit, briefly press the Power/Settings button while the iron is on. The display will toggle between °C and °F.

7.3 Using the Work Light

The integrated work light automatically activates when the soldering iron is in use, providing illumination to improve soldering precision and efficiency, especially in dimly lit areas.

7.4 Soldering Technique

• Ensure the components to be soldered are clean and free of oxidation.
• Apply a small amount of rosin/welding flux to the joint if necessary.
• Touch the hot soldering iron tip to both the component lead and the PCB pad simultaneously to heat them.
• Once heated, apply soldering wire to the joint, allowing it to flow evenly. Do not apply solder directly to the iron tip.
• Remove the soldering wire, then remove the iron tip. Allow the joint to cool without disturbance.

7.5 Sleep Function

The soldering iron is equipped with a sleep function to conserve battery and prevent accidental overheating. If left inactive for 10 minutes, the iron will enter sleep mode, stopping the heating process. The sleep indicator light will be on.

To wake up the soldering iron and resume heating, simply press any button.

8. Maintenance

8.1 Tip Cleaning and Tinning

• Regularly clean the soldering tip using the included cleaning sponge (dampened, not soaking wet) or a brass wire cleaner.
• After cleaning, re-tin the tip by applying a small amount of fresh solder. This helps prevent oxidation and prolongs tip life.
• Never file or sand the tip, as this can damage its protective plating.

8.2 Storage

When not in use, ensure the soldering iron is turned off and completely cooled. Store it in its protective case to prevent damage to the tip and body.

9. Troubleshooting

10. User Tips

• For delicate work, use the pointed tip and a lower temperature setting.
• The knife head tip is excellent for drag soldering or removing components with multiple pins.
• Always ensure your work area is well-lit; the built-in work light is helpful, but additional lighting can improve precision.
• Practice on scrap electronics before working on important projects to get a feel for the iron's heat and response.

11. Warranty and Support
