4. Operating Instructions
The YIHUA 982D-I PRO offers a range of features for precise and efficient soldering.
4.1 Power On/Off
To power on the unit, press the main power switch located on the rear of the station. The full-color LCD display will illuminate, showing the YIHUA logo during startup, then displaying the current and set temperatures.
4.2 Temperature Adjustment
The temperature can be adjusted from 90°C to 450°C (194°F to 842°F) using the rotary knob on the front panel. Turn the knob clockwise to increase the temperature and counter-clockwise to decrease it.
4.3 Customizable Temperature Presets
The station features four customizable temperature preset channels (CH1, CH2, CH3, CH4). These allow you to quickly switch between frequently used temperature settings.
- CH1 (300°C/572°F): Recommended for Tinning & Cleaning.
- CH2 (350°C/662°F): Recommended for General Soldering.
- CH3 (380°C/716°F): Recommended for Tinning & Cleaning.
- CH4 (400°C/752°F): Recommended for Ground Planes.
To set a preset, adjust the temperature to your desired value, then press and hold the corresponding channel button (CH1-CH4) until the setting is saved.
4.4 Dual Tweezers Operation
The C716C tweezers handpiece allows for simultaneous heating of two points, making it ideal for desoldering small SMD components.
4.5 Sleep Mode and Automatic Shutdown
The station features intelligent sleep and automatic shutdown functions to conserve energy and extend the lifespan of the heating elements.
- Sleep Mode: When the handpiece is placed in its holder, the station enters a low-wear idling sleep mode, reducing the tip temperature to 200°C (392°F). This mode is adjustable from 1 to 10 minutes.
- Automatic Shutdown: If the handpiece remains in sleep mode for an extended period (configurable), the unit will automatically shut down.
4.6 Password Protection
The station can be password-locked to prevent unauthorized changes to settings. Refer to the built-in digital manual for instructions on configuring and using the password lock.
4.7 Buzzer and Temperature Unit Settings
The unit allows you to toggle the buzzer sound ON/OFF and switch between Celsius (°C) and Fahrenheit (°F) temperature units. These settings can be accessed through the menu on the display.
5. Maintenance
Proper maintenance ensures the longevity and optimal performance of your soldering station.
5.1 Tip Cleaning and Replacement
Regularly clean the soldering tips using the provided sponge or brass wool. The integrated holder features a groove for easy, tool-free tip removal and installation.
5.2 General Cleaning
Wipe the main unit and handpieces with a soft, damp cloth. Do not use abrasive cleaners or solvents. Ensure the unit is unplugged and cooled down before cleaning.
6. Troubleshooting
This section addresses common issues you might encounter with your soldering station.
6.1 Automatic Temperature Calibration
If you suspect temperature inaccuracies, perform an automatic temperature calibration. This feature ensures consistent temperature accuracy without the need for external thermometers.
Calibration Steps (refer to built-in digital manual for detailed visual guide):
- Adjust the temperature to 250°C (482°F) or higher.
- Pick up the handpiece and allow it to stabilize.
- Press and hold the temperature calibration button for approximately 2 seconds.
- Turn the knob to select Tool A/B calibration.
- Place the soldering iron tip in full contact with the thermocouple in the calibration port.
- Press the knob to exit once calibration is successful.
6.2 Digital Manual (Built-in)
The unit includes a built-in digital manual accessible via the menu. This manual provides detailed instructions and diagrams for various functions, including setup, calibration, and password configuration.
