6. Bedienungsanleitung
6.1 Ein-/Ausschalten
Once connected to a power source, the soldering iron will typically power on automatically. To power off, disconnect the C2C cable.
6.2 Temperatureinstellung
- The 0.99-inch IPS LCD color screen displays the current temperature.
- Use the adjustment buttons (usually '+' and '-' or similar) on the handle to increase or decrease the target temperature.
- Das Bügeleisen wird sich schnell auf die eingestellte Temperatur erhitzen.
6.3 Sleep Standby Function
The soldering iron features an intelligent sleep standby function. If inactive for a set period, it will automatically enter sleep mode to conserve energy and prolong tip life. Movement or pressing a button will wake it up.
6.4 Allgemeine Löt-Tipps
- Ensure the soldering tip is clean and tinned before use.
- Apply a small amount of solder to the tip to improve heat transfer.
- Heat both the component lead and the PCB pad simultaneously with the soldering iron tip.
- Apply solder to the heated joint, not directly to the iron tip.
- Remove the solder and then the iron, allowing the joint to cool naturally.
