5. Operating Instructions
5.1 Power On/Off
Locate the ON/OFF switch on the side of the soldering station. Flip the switch to 'ON' to power on the unit. The LCD display will illuminate and show the current temperature. Flip to 'OFF' to power down.
5.2 Temperature Adjustment
The soldering station offers two methods for temperature adjustment:
- Precise Adjustment: Use the (+) and (-) buttons to adjust the temperature in single-degree increments within the 200℃ to 480℃ range. Long-pressing these buttons will change the temperature in 10-degree increments.
- Preset Temperatures: Press the Function Key (gear icon) to cycle through three preset temperatures: 200℃, 350℃, and 420℃.

5.3 ℃/℉ Conversion
To switch between Celsius (℃) and Fahrenheit (℉) temperature units, simultaneously press and hold the (+) and (-) buttons for a few seconds until the unit changes on the display.

5.4 Power-On Memory
The soldering station is equipped with a power-on memory function. When the unit is turned off and then back on, it will automatically resume operation at the last set temperature, eliminating the need to reset it each time.

5.5 Auto Sleep Function
For safety and to extend the life of the soldering iron tip, the station features an auto-sleep mode. If the soldering iron is inactive for more than 10 minutes, the temperature will automatically drop to a constant 180℃. To exit sleep mode, simply pick up the soldering iron or press any button.

6. Maintenance
6.1 Soldering Tip Cleaning
Regularly clean the soldering tip using the included copper wire ball. This helps remove oxidation and solder residue, ensuring optimal heat transfer and prolonging tip life. Avoid using abrasive materials or excessive force.
6.2 Temperature Calibration
If the actual temperature of the soldering iron deviates from the set temperature, you can perform a temperature calibration:
- With the unit powered on, long-press the Function Key (gear icon) for approximately 3 seconds.
- The display will show a calibration value (e.g., "-04℃"). This indicates the current temperature offset.
- Use the (+) and (-) buttons to adjust the offset. The setting range is typically -50℃ to +50℃. Adjust until the displayed temperature matches a known accurate external thermometer reading of the tip.
- Press the Function Key again to save the setting and complete the calibration.

6.3 General Care
Keep the soldering station clean and free from dust and debris. Store it in a dry environment when not in use. Periodically check all connections for tightness and wear.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Station does not power on | No power supply; Power switch off; Damaged power cable. | Check power outlet; Ensure power switch is ON; Inspect power cable for damage and replace if necessary. |
| Soldering iron not heating | Iron not properly connected; Heating element failure; Incorrect temperature setting. | Ensure iron connector is secure; Contact support if heating element is suspected; Verify temperature setting is above 180°C (sleep mode). |
| Temperature display is inaccurate | Needs calibration; Faulty sensor. | Perform temperature calibration (see Section 6.2); Contact support if calibration does not resolve the issue. |
| Error Code 'E-2' displayed | Internal sensor error or heating element issue. | Turn off the station, unplug, wait a few minutes, then restart. If the error persists, contact SEEKONE customer support. |
