3. Power Connection: Connect the power cord to a suitable power outlet (220V or 110V, depending on your model).

4.2. Operating Instructions

1. Power On: Plug in the soldering iron. The digital display will light up, showing the current temperature.
2. Temperature Adjustment: Use the '+' and '-' buttons on the handle to adjust the desired temperature. The temperature range is 120°C to 550°C. The digital display will show the set temperature.
3. Heating: The ceramic heating core will quickly reach the set temperature. Wait for the temperature to stabilize before beginning work.
4. Soldering: Apply solder to the joint, ensuring proper contact with the heated tip.
5. Smart Sleep: If the soldering iron is left idle for 30 minutes, it will automatically enter sleep mode. To wake it up, simply press any button.
6. Power Off: Unplug the soldering iron from the power outlet after use. Allow the tip to cool down completely before storing.

5. Maintenance and Care

• Cleaning: Clean the tools with a dry cloth. Do not use corrosive chemicals.
• Rust Prevention: Avoid prolonged contact with hand sweat. Apply a small amount of anti-rust oil to the metal parts before storage if necessary.
• Inspection: Inspect the soldering iron and tips for wear, deformation, or damage before each use. If damaged, stop using immediately and replace any faulty components.
• Tip Care: Keep soldering tips clean and tinned to ensure optimal heat transfer and longevity. Use a damp sponge or brass wool to clean the tip during use.

6. Troubleshooting

This section addresses common issues you might encounter with your RELIFE 936 Soldering Iron.

• Iron not heating: Check if the power cord is securely plugged into a working outlet. Ensure the power button (if any) is on. Inspect the power cord for any visible damage.
• Temperature not stable: Ensure the tip is properly seated and clean. Fluctuations can occur if the tip is loose or heavily oxidized.
• Poor solder joints: Verify the temperature setting is appropriate for the solder and components being used. Ensure the tip is clean and properly tinned.
• Iron enters sleep mode unexpectedly: The smart sleep function activates after 30 minutes of inactivity. If it activates during active use, ensure you are occasionally interacting with the iron (e.g., pressing a button) or adjust your workflow.
