Safety Information
Always observe the following safety precautions when using the soldering station:
- Ensure the soldering station is placed on a stable, heat-resistant surface.
- Work in a well-ventilated area to avoid inhaling solder fumes.
- Wear appropriate personal protective equipment, including safety glasses.
- Do not touch the soldering tip or heated parts of the iron, as they can reach very high temperatures.
- Always return the soldering iron to its holder when not in use.
- Keep flammable materials away from the work area.
- Unplug the unit from the power outlet when not in use or before cleaning/maintenance.
- Do not operate the soldering station if the power cord or plug is damaged.
Setup
- Unpack Components: Carefully remove all items from the packaging.
- Connect Soldering Handle: Insert the soldering handle's connector into the designated port on the front of the soldering station.
- Place Soldering Iron in Holder: Position the soldering iron securely in the handle sleep seat. Ensure the anti-scalding silicone pad is correctly placed if applicable.
- Connect Power: Plug the power cable into the power inlet on the back of the soldering station, then connect the other end to a suitable AC100~240V, 50/60Hz power outlet.
- Ground Wire Connection (Optional but Recommended): If your setup requires it, connect the ground wire to an appropriate grounding point.

Operating Instructions
- Power On: Flip the power switch on the back of the soldering station to the 'ON' position. The LCD display will illuminate, showing the current temperature and set temperature.
- Temperature Adjustment: Use the 'Up' and 'Down' buttons on the front panel to set your desired working temperature. The intelligent PID control will quickly bring the tip to the set temperature.
- Rapid Warming: The station features a special heating method that allows for quick tin melting in approximately 6 seconds, and rapid temperature recovery. You can pick up the handle and begin welding without significant waiting time.
- Intelligent Automatic Sleep Function: When the soldering iron is placed in its holder and remains idle for a set period, the station will automatically enter a sleep mode, reducing the tip temperature. This extends the service life of the welding tip by up to 5 times. The last set temperature is automatically saved.

Maintenance
- Tip Cleaning: Regularly clean the soldering tip using the provided copper wire ball or a damp sponge. This helps maintain optimal performance and extends tip life.
- Station Cleaning: Keep the soldering station and holder clean from solder splashes and debris. Use a dry cloth for cleaning.
- Handle Care: The handle is made of high-quality, high-temperature resistant materials. Avoid excessive force or dropping the handle to prevent damage.
- Tip Replacement: To replace a soldering tip, ensure the station is off and the tip has cooled down. Carefully pull out the old tip and insert the new one.

Troubleshooting
- No Power: Check if the power cable is securely connected to both the station and the power outlet. Ensure the power switch is in the 'ON' position.
- Tip Not Heating: Verify that the soldering handle is properly connected to the station. Check if the tip is correctly inserted. If the issue persists, the tip or heating element might need replacement.
- Inconsistent Temperature: Ensure the tip is clean and properly tinned. Environmental factors (e.g., strong drafts) can affect temperature stability. If the problem continues, contact support.
- Soldering Iron Not Entering Sleep Mode: Check if the soldering iron is correctly placed in the handle sleep seat. Ensure no obstructions prevent proper seating.
