5. Operating Instructions

5.1 Power On/Off

Press the main power switch to turn the unit on or off. The LCD display will illuminate.

5.2 Hot Air Rework Station Operation

Temperature Range: 100℃ to 480℃ (212℉ to 896℉).
Temperature Adjustment: Use the '+' and '-' buttons under 'SMD REWORK' to adjust the hot air temperature.
Air Volume Adjustment: Use the rotary knob in the center to adjust the air volume.
Auto Start/Stop: When the hot air gun is lifted from its holder, it will rapidly heat up to the set temperature. When placed back in the holder, it will automatically cool down and enter standby mode.

5.4 Memory Channels (CH1, CH2, CH3)

The station features three memory channels for both the hot air rework station and the soldering station. These allow you to store and quickly recall frequently used temperature settings.

To Set: Adjust the temperature to your desired value, then press and hold the corresponding CH button (CH1, CH2, or CH3) until the display flashes, indicating the temperature is saved.
To Recall: Simply press the desired CH button to instantly switch to the stored temperature.

5.5 Sleep Mode and Auto Shutdown

Sleep Mode: If the soldering iron is left in its stand for 10 minutes without activity, it will automatically enter sleep mode, reducing the tip temperature to prevent oxidation and save energy. The display will show 'SLP'.
Auto Shutdown: If the soldering iron remains in sleep mode and is not woken up after 30 minutes, the station will automatically shut down for safety and energy conservation.
