How to use
Connect the soldering iron to an appropriate 4.5 V DC power source and allow the tip to reach working temperature according to the solder manufacturer's recommendations. Clean the tip and components before soldering to ensure good thermal contact and reliable joints. Use a suitable solder alloy and apply solder to the heated joint, not directly to the tip. Work on small sections at a time, allowing cooling between operations to avoid overheating nearby components. After finishing, disconnect the power supply and store the iron safely once the tip has cooled completely.
