5. Bedienungsanleitung

5.1 YIHUA 8786D-I Soldering & Rework Station

  1. Einschalten: Flip the main power switch to the 'ON' position.
  2. Auswahlmodus: 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. Lötkolben-Schlafmodus: 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. Ausschalten: Turn off the individual station switches, then the main power switch.

  1. Einschalten: Press the 'POWER' button to turn on the unit. The LCD display will illuminate.
  2. Lautstärke anpassentage: Verwenden Sie die Taste „VOL“.TAGE' Grob- und Feineinstellknöpfe zum Einstellen der gewünschten Ausgangslautstärketage (0-30V). Observe the voltage reading on the LCD display.
  3. Adjust Current Limit: Use the 'CURRENT' coarse and fine adjustment knobs to set the desired current limit (0-5A). This protects your circuit from overcurrent.
  4. Konstante Lautstärketage (CV) / Constant Current (CC) Mode: The unit automatically switches between CV and CC modes depending on the load. 'CV' indicates Constant Voltage mode, and 'CC' indicates Constant Current mode.
  5. Schutzfunktionen: The unit includes Over VoltagÜberspannungsschutz (OVP) und Überstromschutz (OCP) zum Schutz der angeschlossenen Geräte und des Netzteils selbst.
  6. Ausschalten: Press the 'POWER' button to turn off the unit.
