5. Operating Instructions

5.1 General Operation

• Power On: Flip the main power switch on the unit. The digital displays will illuminate.
• Temperature Unit Conversion: The unit supports both Celsius (°C) and Fahrenheit (°F). Refer to the manual for specific button combinations or settings to switch between units.
• Calibration Function: The unit features a calibration function for precise temperature control. Consult the full manual for detailed calibration procedures to ensure greater temperature precision.

This close-up image highlights the dual digital displays on the main unit, showing temperature readings for both the soldering iron and the hot air gun, enabling real-time monitoring.

5.2 Hot Air Gun Operation

The hot air gun offers both manual and automatic modes for various applications.

• Power On/Off: Use the "HOTAIR" switch to turn the hot air gun function on or off.
• Temperature Adjustment: Use the "HOTAIR" temperature knob to set the desired temperature (212-932°F / 100-500°C). The display will show the set temperature.
• Air Volume Adjustment: Use the "AIR" knob to adjust the airflow (up to 120L/min, 1-8 levels).
• Manual Mode: When the hot air gun is removed from its holder, it will maintain the set temperature and continuous airflow. This mode is suitable for continuous work.
• Automatic Mode (Standby Mode): When the hot air gun is placed back into its holder, the unit will automatically cool down and enter standby mode. This protects the heating element and extends the gun's lifespan.

Figure 6: Hot Air Gun Operating Modes

This image illustrates the two operating modes of the hot air gun: Manual Mode (continuous airflow when off the stand) and Automatic Mode (cooling down and standby when placed on the stand).

Figure 7: Manual Mode Operation

This image shows the hot air gun being used in manual mode, demonstrating continuous airflow for desoldering components from a circuit board.

Figure 8: Automatic Mode Activation

This image depicts the hot air gun placed back into its stand, activating the automatic mode where airflow continues without heating to cool down the unit.

5.3 Soldering Iron Operation

• Power On/Off: Use the "SOLDERING" switch to turn the soldering iron function on or off.
• Temperature Adjustment: Use the "SOLDERING STATION" temperature knob to set the desired temperature (212-932°F / 100-500°C). The display will show the set temperature.
• Tip Selection: Choose the appropriate soldering tip for your task from the included set (I/B/K/3.2D/3C).
• Sleep Mode: The soldering iron features a sleep mode to reduce wear and extend the lifespan of the soldering tip and heating element when not actively in use.
