Finally, press 'SET' again to save and exit the calibration mode.
7. การบำรุงรักษา
Proper maintenance ensures the longevity and optimal performance of your soldering station.
7.1. Soldering Tip Care
- การเลือกอุณหภูมิ: High temperatures can degrade the soldering tip's function. Utilize the lowest possible temperature for your soldering task. The A9PRO's excellent temperature recovery allows for effective soldering at lower temperatures, protecting sensitive components.
- การทำความสะอาดปกติ: Regularly clean the soldering tip using the copper wire cleaning ball provided. After soldering, residual flux can lead to oxidation and carbide buildup, which damages the tip, causes soldering errors, and reduces heat conduction.
- Cleaning When Not in Use: Avoid leaving the soldering iron at high temperatures for extended periods when not in use. This can cause solder on the tip to oxidize, significantly reducing its heat conduction efficiency.
- หลังการใช้แต่ละครั้ง: After completing your work, clean the soldering iron tip and apply a fresh layer of tin (re-tinning) to prevent oxidation.
7.2. Checking and Cleaning the Soldering Tip
- อย่าทำ File: อย่าใช้ file or abrasive material to remove oxide from the soldering tip.
- ขั้นตอน:
- ตั้งอุณหภูมิไว้ที่ 250°C (482°F)
- Once the temperature stabilizes, clean the tip with a cleaning sponge or the copper wire brush and inspect its condition.
- If the tinned part of the soldering iron tip shows black oxide, re-tin the tip with a new layer of solder. Then, wipe the tip with a clean sponge until all oxide is removed, and re-tin it again.
- If the soldering iron tip is deformed or heavily rusted, it must be replaced with a new one.
7.3. Heating Core Replacement
The AIFEN A9PRO uses a heating core integrated with the welding head. To replace it:
- Turn off the power to the soldering station.
- Allow the heating core to cool down completely.
- Carefully unplug the old heating core/tip assembly.
- Insert the new heating core/tip assembly.

8 การแก้ไขปัญหา
If you encounter any issues with your AIFEN A9PRO Soldering Station, refer to the following common problems and solutions:
- Display shows "S-E" with intermittent buzzer:
This indicates that the heating core is either burnt out, disconnected, or not properly placed in the handle. Check the heating core and its connection to the handle. Ensure the tip is fully inserted.
- Display shows "H-A" with continuous beeping:
This signifies that the heating core has a short circuit. Immediately turn off the power. Remove the short-circuited heating core. Wait for 3 minutes, then power on the station again. Replace the faulty heating core if necessary.
9. เคล็ดลับผู้ใช้
- Choosing the Right Tip: The A9PRO is compatible with C115, C210, and C245 series tips.
- C115 Tips: Best for ultra-fine circuits under a microscope, such as multi-layer circuit boards or complex flying leads. Use cutter tips for small solder joints and pointed tips for tiny solder joints.
- C210 Tips: Ideal for mobile phone repairs, car remote controls, precision small electrical appliances, and cables. Use cutter tips for small to medium solder joints (e.g., IC bases) and sharp tips for small flying wires and small solder joints.
- C245 Tips: Recommended for home appliance maintenance, general mobile phone repair, and computer motherboards. These high-power (120W) tips handle both large and small solder joints effectively, though their larger size might make tiny solder joints slightly more challenging.

Figure 7: Guide to selecting appropriate soldering tips for different tasks.
- เล่มที่tagความเข้ากันได้: The A9PRO supports a universal input voltage of AC100-240V. However, ensure you select the correct plug type (e.g., EU plug for 220V regions like Germany, France; US plug for 110V regions like the United States, Canada) to match your local electrical outlets.
10. คำถามที่พบบ่อย (FAQ)
- Q: Is the A9PRO compatible with JCD soldering tips?
- A: The A9PRO is designed for compatibility with AIFEN/SUGON C115, C210, and C245 series tips. Compatibility with other brands like JCD is not guaranteed, and using non-compatible tips may affect performance or damage the unit.
- Q: Can C210 tips be used with a C115 handle?
- A: The A9PRO station itself supports C115, C210, and C245 series tips. However, each tip series typically requires its corresponding handle (e.g., C210 tips with a C210 handle). Ensure you use the correct handle for the tip series you intend to use.
- Q: What is the thinnest tip available for the A9PRO?
- A: The C115 series tips are generally the thinnest and most precise, ideal for micro-soldering applications. Refer to the "User Tips" section for guidance on selecting the appropriate tip for your work.
