6. Operating Instructions
6.1 Power On/Off
Flip the main power switch located on the front panel to turn the unit ON or OFF.
6.2 Soldering Station Operation
- Temperature Adjustment: Use the '+' and '-' buttons or the rotary knob in the "SOLDERING STATION" section to set the desired temperature. The current temperature will be displayed on the LED screen.
- Auto Sleep Mode: If the soldering iron is not used and remains stationary for longer than 10 minutes, it will automatically enter sleep mode. The display will show "SLP". To resume operation, simply pick up the soldering iron.
6.3 Hot Air Rework Station Operation
- Temperature Adjustment: Use the '+' and '-' buttons or the rotary knob in the "REWORK STATION" section to set the desired hot air temperature.
- Air Volume Adjustment: Use the dedicated rotary knob to adjust the air flow rate.
- Auto Start/Stop: Pick up the hot air gun from its holder to activate it. The unit will begin heating to the set temperature. When you place the hot air gun back into its holder, it will automatically cool down and enter standby mode.
6.4 Digital Temperature Calibration
This function allows you to fine-tune the temperature display for accuracy:
- Initiate Calibration: For the soldering station, simultaneously press the temperature "+" and "-" buttons.
- Measure Actual Temperature: Use an external temperature measuring device (e.g., a thermometer designed for soldering tips) to measure the actual temperature of the soldering iron tip or hot air stream.
- Adjust Display: Use the '+' and '-' buttons to adjust the displayed temperature on the station to match the actual measured temperature.
