4. Einrichtungsanweisungen

4.1 YIHUA 939D+ Soldering Station Setup

  1. Place the soldering station on a stable, heat-resistant surface.
  2. Connect the soldering iron handle to the 'IRON' receptacle on the front panel of the 939D+ station. Ensure a secure connection.
  3. Place the soldering iron into its holder.
  4. Insert the cleaning sponge into the sponge tray and dampen it slightly with water. Alternatively, place the brass ball cleaner in its designated area.
  5. Connect the power cord to the back of the soldering station and then to a 110-127V AC power outlet.

4.2 YIHUA 305D-IV DC Lab Power Supply Setup

  1. Position the power supply on a stable surface, ensuring adequate ventilation around the unit.
  2. Connect the power cord to the back of the power supply and then to a 110-127V AC power outlet.
  3. For output, connect your test leads or device to the output terminals (red for positive, black for negative, yellow for ground) on the front panel.

5.1 YIHUA 939D+ Digital Soldering Station Operation

  1. Einschalten: Flip the ON/OFF power switch. The digital display will illuminate, showing the current temperature.
  2. Temperatureinstellung: Rotate the temperature adjustment knob to set the desired temperature. The range is 392-896°F (200-480°C). The display will show the set temperature briefly, then return to the actual tip temperature.
  3. Auswahl der Temperatureinheit: Press the °C/°F button to switch between Celsius and Fahrenheit display modes.
  4. Kalibrierung: If necessary, use the CAL adjustment point for temperature calibration. Refer to advanced user guides for detailed calibration procedures.
  5. Löten: Once the desired temperature is reached and stabilized, clean the soldering iron tip using the damp sponge or brass ball. Apply solder to the joint, not directly to the iron tip.
  6. Ausschalten: After use, turn off the power switch and allow the iron to cool completely in its holder before storing.

5.2 YIHUA 305D-IV Regulated DC Lab Power Supply Operation

  1. Einschalten: Press the 'POWER' button on the front panel. The LCD display will light up.
  2. Bandtage-Einstellung: Verwenden Sie die Taste „VOL“.TAGE' Grob- und Feineinstellknöpfe zum Einstellen der gewünschten Ausgangslautstärketage (0-30V). The display shows the current voltage Einstellung.
  3. Aktuelle Anpassung: Use the 'CURRENT' coarse and fine adjustment knobs to set the desired current limit (0-5A). This acts as a maximum current draw for the connected device.
  4. Konstante Lautstärketage (CV) / Constant Current (CC) Modes: The unit automatically switches between CV and CC modes. When the load draws less current than the set limit, it operates in CV mode (maintaining set voltage). If the load attempts to draw more current than the set limit, it switches to CC mode (maintaining set current, voltage Tropfen).
  5. Schutzfunktionen: The 305D-IV includes short-circuit protection and overcurrent protection. In case of a fault, the unit will limit output to protect itself and the connected device.
  6. Ausschalten: Press the 'POWER' button again to turn off the unit.

6. Wartung

6.1 Wartung der Lötspitze

  • Reinigung: Regularly clean the soldering iron tip using the damp sponge or brass ball cleaner. This removes oxidation and old solder, extending tip life and improving heat transfer.
  • Konservieren: After cleaning and before storing, apply a small amount of fresh solder to the tip (tinning). This protects the tip from oxidation.
  • Spitzenersatz: If a tip becomes excessively worn or damaged, replace it with a new compatible YIHUA tip. Ensure the iron is cool before changing tips.

6.2 Allgemeine Reinigung der Einheit

  • Ensure both units are powered off and unplugged before cleaning.
  • Wipe the exterior surfaces of the soldering station and power supply with a soft, dry cloth.
  • Verwenden Sie keine scheuernden Reiniger oder Lösungsmittel, da diese das Material beschädigen können.asing oder Anzeige.
  • Halten Sie die Lüftungsöffnungen frei von Staub und Schmutz.
