Setup
1. Charging the Soldering Iron
Before first use, fully charge the soldering iron. Connect the provided USB Type-C cable to the charging port on the soldering iron and a compatible USB power source (e.g., computer, USB adapter, power bank). The charging time is approximately 90 minutes.

Figure 2: Charging the soldering iron via its Type-C port. A red light indicates charging, and a green light indicates charging is complete.
The LED indicator light will be red during charging and turn green when charging is complete.
2. Installing Soldering Tips
Ensure the soldering iron is off and cool before installing or replacing tips. To install a tip, gently push it into the heating element opening until it is securely seated. To remove, pull the tip straight out. The kit includes three types of tips: Round, Horseshoe, and Knife Head, for various soldering tasks.

Operating Instructions
1. Power On/Off
Press and hold the power button (usually marked with a circle and a line) for a few seconds to turn the soldering iron ON or OFF. The LCD screen will illuminate upon power-on.
2. Temperature Adjustment
Once powered on, the LCD will display the current temperature. Use the '+' and '-' buttons to adjust the temperature. The soldering iron offers five preset temperature levels:
- 260°C (500°F)
- 300°C (572°F)
- 340°C (644°F)
- 380°C (716°F)
- 420°C (788°F)

3. Switching Temperature Units (°C/°F)
To switch between Celsius (°C) and Fahrenheit (°F), double-click the power button (or the main adjustment button, depending on the model variant). The display will change accordingly.

Figure 6: Double-clicking the button allows toggling the temperature display between Celsius and Fahrenheit.
4. Sleep Mode
The soldering iron is equipped with an automatic sleep mode to conserve battery and enhance safety. If left idle for 10 minutes, the soldering iron will enter sleep mode, stopping the heating process. The sleep indicator light will turn on.
The hibernate function automatically turns off after 5 minutes of being turned on if no activity is detected.
To wake up the soldering iron and resume heating, press any button.

5. Basic Soldering Use
- Select the appropriate soldering tip for your task and ensure it is securely installed.
- Turn on the soldering iron and set your desired temperature. Wait for the iron to reach the set temperature (approximately 6 seconds for tinning).
- Clean the tip using the damp sponge on the soldering stand.
- Apply a small amount of solder to the tip to tin it, ensuring good heat transfer.
- Place the hot tip against the components to be soldered, heating both simultaneously.
- Apply solder to the heated joint, not directly to the iron tip. Allow the solder to flow and create a strong connection.
- Remove the solder and then the iron. Allow the joint to cool naturally.
- Always return the soldering iron to its stand when not in use.

Maintenance
- Tip Cleaning: Regularly clean the soldering tip using the damp sponge provided in the stand. This helps remove oxidation and ensures efficient heat transfer. Never file or sand the tip.
- Tip Tinning: After each use, or if the tip becomes discolored, apply a small amount of fresh solder to the tip to keep it tinned. This prevents oxidation and prolongs tip life.
- Storage: Store the soldering iron in its protective case when not in use. Ensure the iron is completely cool before storing. Keep it in a dry place away from direct sunlight and moisture.
- Battery Care: For optimal battery life, avoid fully discharging the battery frequently. Charge the iron when the low battery alarm (L-0) appears. If storing for extended periods, charge the battery to about 50% every few months.
Troubleshooting
This section addresses common issues you might encounter with your soldering iron.
| Problem/Error Code | Possible Cause | Solution |
|---|---|---|
| H-E (Heater Core Failure) | The heating core or soldering tip is not properly inserted or is faulty. | Ensure the soldering tip is fully and correctly inserted. If the problem persists, the heating core or tip may need replacement. |
| L-0 (Low Battery Alarm) | The battery charge is critically low. | Recharge the soldering iron using the provided Type-C cable. |
| Iron not heating up | Not powered on, low battery, or tip not properly installed. | Ensure the iron is powered on. Check battery level and charge if necessary. Verify the soldering tip is securely installed. |
| Temperature not stable | Tip is dirty or oxidized, or not properly tinned. | Clean and re-tin the soldering tip. Ensure the tip is fully inserted. |
