5. Operating Instructions
5.1 Power On/Off
To power on the unit, flip the main power switch located on the rear of the station. The LED display will illuminate. To power off, flip the switch back.
5.2 Temperature Adjustment
The soldering station features a digital LED display for precise temperature control. The temperature range is 200°C to 480°C (392°F to 896°F).
- Adjusting Temperature: Use the rotary knob on the front panel to increase or decrease the desired temperature. The display will show the set temperature.
- Quick Heating: The soldering iron heats up rapidly, reaching operating temperature in approximately 5 seconds.
