6. Connexió d'alimentació: Connect the power cord to the unit's power inlet and then to a standard 110-127V AC power outlet.
7. Encesa inicial: Flip the main power switch located on the front panel to the "ON" position. The digital displays will illuminate.

5. Instruccions de funcionament

5.1. Soldering Station

1. Encès: Press the "SOLDER" power button to activate the soldering iron.
2. Ajust de temperatura: Use the "TEMP. SET" up/down buttons for the soldering station to adjust the desired temperature. The display shows the set temperature and actual temperature.
3. Unitats de temperatura: The unit supports both Celsius (°C) and Fahrenheit (°F) display. Refer to the manual's settings section for switching between units.
4. Funció de son: The soldering iron features a sleep mode. When placed in its holder, it will automatically enter sleep mode after a set period to conserve energy and extend tip life. It will rapidly heat up when picked up.

5.2. Hot Air Rework Station

1. Encès: Press the "REWORK" power button to activate the hot air gun.
2. Ajust de temperatura: Use the "TEMP. SET" up/down buttons for the rework station to adjust the desired hot air temperature.
3. Ajust del flux d'aire: Use the "AIR" knob to control the airflow intensity.
4. Apagada automàtica: The hot air gun will automatically cool down and shut off when placed in its stand, extending the heating element's lifespan.
5. Mode manual: A "MAN" button allows the hot air gun to run continuously, bypassing the automatic shut-down feature when in the stand.

5.3. DC Power Supply

1. Encès: Press the "POWER" button in the DC Power section to activate the power supply.
2. Voltage Ajust: Use the "VOLTAGE" knob to set the desired output voltagi (0-15V).
3. Ajust actual: Use the "CURRENT" knob to set the desired current limit (0-3A).
4. Output/Test Modes: The power supply has "OUTPUT DISPLAY" and "TEST VOLTAGE" modes.
   • Visualització de sortida: Connect your device to the "OUTPUT DISPLAY" terminals. The display will show the actual voltage and current being drawn.
   • Prova Voltage: Connect test leads to the "TEST VOLTAGE" terminals to measure external DC voltage (fins a 35 V).

   Nota:

   The testing section functions are integrated; use ONLY one at a time. Do not use the voltmeter for AC devices or voltages greater than 35V.
5. Port USB: A dedicated 5V 0.5A USB port is available for powering small devices like smartphones. Avoid using it for devices with large power requirements.

6. Manteniment

Regular maintenance ensures the longevity and optimal performance of your YIHUA 853D USB 3A station.

• Soldering Iron Tip Cleaning: Regularly clean the soldering iron tip using the included brass wool cleaner or a damp sponge. This prevents oxidation and ensures efficient heat transfer.
• Replacing Soldering Tips: When a tip becomes worn or damaged, replace it with a new one. Ensure the iron is cool before changing tips.
• Neteja de la boquilla d'aire calent: Clean hot air nozzles as needed to prevent blockages.
• Neteja general: Keep the main unit clean and free of dust and debris. Use a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Emmagatzematge: When not in use, store the unit in a dry, dust-free environment.
