5. Setup

5.1 Attaching/Replacing the Soldering Tip

The electric soldering head can be replaced according to welding needs.

1. Hold the body of the soldering iron with your right hand and gently pull the existing soldering iron tip out.
2. Loosen the stainless steel tube sleeve by turning the copper gear to the right to remove it.
3. Insert the new soldering iron tip into the ceramic heating element.
4. Tighten the stainless steel tube sleeve by turning the copper gear to the left.

5.2 Power Connection

Connect the soldering iron's power plug to an appropriate AC 110V~240V power outlet. Ensure the outlet matches the plug type (US or EU) and voltage requirements.

5.3 Soldering Iron Stand

Always place the soldering iron securely in its designated stand when not in active use. This prevents accidental burns and damage to your workspace.

6. Operating Instructions

6.1 Power On/Off

• To power on, long press the + button for 6 seconds.
• To power off, long press the + button for 6 seconds again.

6.2 Temperature Adjustment

Figure 5: Temperature Adjustment Controls

• Press the + button once to increase the temperature by one degree.
• Long press the + button to continuously increase the temperature.
• Press the - button once to decrease the temperature by one degree.
• Long press the - button to continuously decrease the temperature.
• When no button is pressed for 3 seconds, the newly set temperature will be memorized and will be maintained at the next startup.
• After setting the temperature, allow approximately 30-50 seconds for the heating core to reach the set temperature and for the soldering iron tip to stabilize at that value.

6.3 Temperature Unit Switch (Celsius/Fahrenheit)

• Press the # button once to switch the temperature display between Celsius (°C) and Fahrenheit (°F).

6.4 Temperature Calibration

It is recommended to calibrate the soldering iron at approximately 320°C for optimal accuracy.

1. Power on the soldering iron and allow it to heat for 90 seconds.
2. Place the soldering iron tip on a thermometer, ensuring full contact between the tip and the thermocouple by adding a small amount of solder.
3. Wait 2-4 seconds after the thermometer shows a stable temperature, then record the thermometer's reading.
4. Remove the soldering iron from the thermometer.
5. Press the + and - buttons simultaneously to enter the temperature calibration interface.
6. Input the adjustment amount:
   • If the set temperature was 290°C and the measured temperature was 282°C, the difference is +8°C. Input '08' on the LCD.
   • If the set temperature was 290°C and the measured temperature was 300°C, the difference is -10°C. Input '-10' on the LCD.
7. Press the + and - buttons simultaneously again to exit the temperature calibration interface.

6.5 Basic Soldering Techniques

Figure 6: Basic Soldering Operations

• Preheating with Rosin: After the soldering iron has preheated to the desired temperature, gently touch the tip to rosin to clean and prepare it for soldering.
• Applying Solder: Once the soldering iron tip reaches the set temperature, touch the solder wire to the joint and the heated tip. The solder should melt and flow smoothly onto the connection.

6.6 Using Desoldering Aids

Figure 7: 6 Pieces of Desoldering Aids and Their Uses

• Hook: Used for removing resistance elements by dissolving and lifting them.
• Indenter: Useful for soldering small electronic components by pressing and positioning them before soldering.
• Cross: Designed for fixing or adjusting components and component pins, such as resistors and capacitors, for proper molding.
• Hammer: Employed to clean solder-plugged holes and expand printed circuit board holes.
• Knife: Can be used to cut copper-clad connecting wire on the printed circuit board, correct circuits, or remove rust.
• Brush: Ideal for cleaning dust and residue on the solder part before soldering, and for cleaning solder balls.

6.7 Using the AN8205C Multimeter (if included)

Figure 8: AN8205C Multimeter Features

The AN8205C Multimeter is a versatile tool for electrical measurements. Refer to its dedicated manual for detailed instructions. Key functions include:

• DC Measurement
• Temperature / Transistor testing
• AC Voltage / Diode / Resistor measurement
• DC Voltage / On-off Buzzer for continuity checks

7. Maintenance

7.1 Soldering Tip Cleaning

To ensure optimal performance and longevity of your soldering tips:

• After each use, clean any residual tin wire or solder from the tip using a damp sponge (often included with the soldering iron stand).
• Ensure the sponge is moist, not soaking wet, to avoid thermal shock to the tip.
• Regular cleaning helps prevent oxidation and maintains efficient heat transfer.

7.2 Silicone Protection Coil

The silicone protection coil at the power cord effectively protects the cord from heat and wear, extending its service life. Periodically inspect the coil and cord for any signs of damage.

8. Troubleshooting

9. User Tips

• Tinning the Tip: Always tin your soldering iron tip with a small amount of solder before and after use. This protects the tip from oxidation and improves heat transfer.
• Proper Ventilation: Always work in a well-ventilated area or use a fume extractor to avoid inhaling harmful solder fumes.
• Cleanliness: Keep your workspace clean and free of debris. A clean tip and clean components lead to better solder joints.
• Practice Makes Perfect: If you are new to soldering, practice on scrap components or wires before working on important projects.
