5. Setup
5.1 Changing the Heating Element
To change the heating element:
- Slot the soldering iron tip into the V-shaped groove.
- Pull the soldering iron to separate the heating element.
- Attach the new heating element to the soldering iron.
- Place the soldering iron tip into the hole and apply gentle pressure to secure the tip to the soldering iron.

5.2 Initial Connection
- Connect the soldering iron and place it into the soldering iron holder.
- Connect the soldering iron holder's power cord to the receptacle at the back of the station.
- If the soldering iron holder and the main unit need to be separated, unscrew the indicated screw.
- Connect the station to a power socket and turn ON the power switch. The soldering station's heating element will begin heating, and the operation indicator will turn ON. The indicator stays ON when heating up, blinks rapidly when the temperature is stabilized, and turns OFF when cooling. When the operation indicator blinks rapidly, the soldering iron's temperature has stabilized and is ready to use.
6. Operating Instructions
6.1 Rapid Heating
The Silverflo 982-I features rapid heating, allowing the soldering iron to reach operating temperature quickly.

6.2 Sleep Mode
This function extends the lifespan of the heating element, conserves energy, and protects the environment. When the soldering iron is placed back into the holder, it will enter sleep mode. If the set temperature is over 250°C (482°F), the temperature will cool to 200°C (392°F). If the set temperature is less than 250°C (482°F), the temperature will cool to 90°C (194°F). Pick up the soldering iron to exit sleep mode.

6.3 Memory Channels (CH1/CH2/CH3)
You can preset temperature configurations in each memory channel for different needs. When soldering, you can select the suitable preset temperature configurations in CH1/CH2/CH3 quickly according to different soldering applications.
- Press the CH1/CH2/CH3 memory channel button to choose the desired memory channel.
- Turn the CH1/CH2/CH3 memory channel knob to set the desired temperature.
- Once done setting, wait for approximately 4 seconds. The setting is complete.

6.4 Automatic Shut-down
The soldering iron enters sleep mode when placed inside the soldering iron holder. At this point, the station's CPU will begin a countdown. If the soldering iron is not picked up within approximately 30 minutes, the soldering station will automatically shut off. To restart the soldering station, pick up the soldering iron.

6.5 Digital Temperature Calibration
Temperature discrepancies may occur due to changes in the environment's temperature or due to the replacement of the heating element and other components. This function allows you to correct these discrepancies, improving work efficiency and extending the lifespan of the soldering iron.
- Set the desired calibrated temperature. Once done setting, wait for approximately 4 seconds and turn OFF the power switch.
- When the station is not turned on, press and hold the temperature adjustment knob and turn ON the power switch at the same time. The display will show the set temperature and three dots.
- When the temperature has stabilized, turn the temperature adjustment knob to enter the temperature measured by a thermometer.
- Once done entering, press the temperature adjustment knob to confirm the entry. The system saves and exits the setting interface.

6.6 F/℃ Conversion
This function allows the station to comply with user preferences in different regions.
- Press and hold the temperature adjustment knob for approximately 2 seconds. The display shows "C" or "F".
- Turn the temperature adjustment knob to select either Fahrenheit or Celsius display mode.
- Once done selecting, press the temperature adjustment knob two times. The system saves and exits the setting interface.
6.7 Buzzer Prompt
This function enables or disables the audible buzzer for notifications.
- Press and hold the temperature adjustment knob for approximately 2 seconds. The display shows "C" or "F".
- Press the temperature adjustment knob once. The display shows "bON", indicating the buzzer prompt is now on.
- Turn the temperature adjustment knob to turn the buzzer prompt ON or OFF.
- Once done setting, press the temperature adjustment knob once. The system saves and exits the setting interface.
6.8 First Use Tip
Upon the first use of the soldering iron, set the temperature to 250°C (482°F). When the iron is just hot enough to melt solder, coat the soldering iron tip with a layer of solder (the use of rosin core solder is recommended), then set the temperature to your desired temperature.

7. Maintenance & Precautions
- If a layer of oxidization forms on the surface of the soldering iron tip, a misconception can be created that the soldering tip cannot heat up properly to melt the solder and do the tinning. But the actual temperatures of both the heating element and soldering tip are high. In such an instance, please do not increase the temperature value confusedly but use a metal wool ball to remove the oxidization following the steps below:
- Set the temperature to 300°C (572°F).
- Once the temperature has stabilized, gently rub the soldering iron tip inside the metal wool ball.
- When the oxidation is partially removed, continue applying solder onto the tip while rubbing it until the soldering tip is completely coated with solder. If the tip is too severely oxidized beyond cleaning, replace the heating element.
- DO NOT use metal files to remove the oxidation on the soldering iron tip. If the soldering iron tip deforms or rusts, replace the heating element.
- DO NOT apply excessive force on the soldering tip when soldering. Doing so will not only damage the iron tip but also not improve the heat transfer.
- When placing the soldering iron back in the holder to idle after a high-temperature operation, adjust the temperature to 250°C (482°F) or below for idling. Failure to do so, and leaving the soldering iron tip to idle on a high-temperature setting will cause the accelerated aging of the heating element and shorten the lifespan of the heating element and soldering iron tip.
- After every operation, clean the soldering iron tip, then tin the tip with a new layer of solder to prevent oxidization.
8. Troubleshooting
Error Codes and Solutions:
- S-E: This is an indication that the station's sensor module is faulty. You need to replace the heating element (the heating element and the sensor modules). Or the soldering iron/heating element is not connected.
- SLP: This is an indication that the soldering station is in Sleep Mode.
- tOP: This is an indication that the system is in over-heat protection mode. The system will automatically restore itself in a short while.
9. User Tips
- The Silverflo 982-I offers precise temperature control and quick heating, which are beneficial for delicate micro-soldering tasks.
- Utilize the memory channels (CH1/CH2/CH3) to quickly switch between frequently used temperature settings for different components or solder types.
- The automatic shut-down and sleep mode features are excellent for extending the lifespan of your heating elements and saving energy, especially during breaks in work.
- Regularly clean and tin your soldering iron tip after each use to prevent oxidation and ensure optimal performance.
