2. توصيل الطاقة: Connect the power cord to the unit and then to a grounded 110-127V AC outlet.
3. اتصالات الإخراج: Connect your load to the output terminals using appropriate test leads. Red for positive (+), Black for negative (-), and Yellow/Green for ground (GND).

5. تعليمات التشغيل

5.1 YIHUA 8786D-I Soldering & Rework Station

1. تشغيل الطاقة: قم بتحريك مفتاح الطاقة الرئيسي إلى وضع "التشغيل".
2. حدد الوضع: Use the dedicated power switches for the Hot Air Rework Station and Soldering Station to activate the desired function.
3. Adjust Hot Air Temperature and Airflow: For the hot air station, use the temperature control buttons (Up/Down) to set the desired temperature (212-896°F). Adjust the airflow using the airflow knob. The unit features temperature stabilization.
4. Hot Air In-Holder Standby Mode: When the hot air gun is placed in its holder, it automatically cools down to 212°F and enters standby mode. It will heat up to the set temperature when removed from the holder.
5. Adjust Soldering Iron Temperature: For the soldering station, use the temperature control buttons (Up/Down) to set the desired temperature (392-896°F). The unit features PID temperature stabilization for consistent heat.
6. Soldering Iron Sleep Mode: The soldering iron enters a 10-minute sleep mode when idle, reducing its temperature to 392°F to minimize tip wear. It quickly reheats when picked up.
7. إيقاف التشغيل: Turn off the individual station switches, then the main power switch.
