4. Setup Instructions
- Connect the Soldering Iron Handle: Insert the connector of the soldering iron handle into the 'HEATER' port on the front of the host unit. Ensure it is securely connected.
- Connect the Power Cord: Select the appropriate power plug (US, EU, UK) for your region, as the station supports universal voltage (110-240V). Connect the power cord to the power cord interface on the rear of the host unit and then to a suitable power outlet.

Choose the correct power plug (US, EU, UK) based on your regional voltage requirements. - Connect the Anti-static Ground Wire: For safety and optimal performance, connect the anti-static ground wire to the static electricity line interface on the rear of the host unit and ensure it is reliably grounded.
- Place the Soldering Iron Stand: Position the dormant seat (stand) on a stable, heat-resistant surface. Place the copper ball and cleaning sponge in their designated areas within the stand.
- Insert the Soldering Iron: Place the soldering iron handle into the dormant seat when not in use.
- Power On: Flip the power switch on the rear of the host unit to the 'ON' position. The display will light up.
5. Operating Modes
5.1. Control Panel Overview

- Handle Interface: Connection point for the soldering iron handle.
- Display: Shows current temperature, error codes, and settings.
- Temperature Regulation Knob: Rotary encoder for adjusting temperature and navigating settings.
- ESD SAFE: Electrostatic Discharge Safe indicator.
- Switch: Main power switch.
- Power Cord Interface: Connection point for the power cord.
- Static Electricity Line Interface: Connection point for the anti-static ground wire.
5.2. Basic Operation
- Temperature Adjustment: Rotate the encoder knob left or right to adjust the temperature. The adjustable range is 100-480°C.
- Temperature Enhancement (One-Click Boost): Click the encoder knob once to increase the heating core temperature by 50°C. This function is valid for set values below 450°C and automatically exits after a set time.
- Manual Standby: In normal operating mode, quickly turn the knob to the left to enter standby mode.
5.3. Automatic Modes
- Automatic Standby Mode: If the handle is idle for a set period (default 60 seconds), the main unit enters standby mode, automatically adjusting the heating element temperature to a user-defined protection level. To exit standby mode and resume normal operation, operate the encoder or pick up the handle.
- Automatic Sleep Mode: If no operation is performed in standby mode for a set period (default 5 minutes), the main unit enters sleep mode, turning off the heating element and cooling to room temperature. To exit sleep mode and restore operation, press the encoder knob or pick up the handle.
- Automatic Memory: The soldering station remembers the last set temperature and other settings when restarted, eliminating the need for repeated adjustments.
- Buzzer Reminder: The built-in buzzer emits different sounds to indicate mode changes, allowing you to understand the station's status without looking at the screen.
5.4. Setting Modes (P01-P06)
- Enter Setting Mode: Press and hold the encoder knob until 'P01' appears on the display.
- Navigate Settings: Click the encoder knob to cycle through setting options (P01, P02, P03, P04, P05, P06).
- Adjust Parameters: Rotate the encoder knob left or right to modify the parameter for the selected option.
- Exit Setting Mode: Press and hold the encoder knob to save changes and exit.
Setting Options:
- P01 (Standby Protection Temperature): Set the standby temperature for the heating core (100-300°C, default 200°C). This should be lower than the operating temperature.
- P02 (Standby Mode Time): Set the idle time before entering standby mode (1-120 seconds, 'oFF' to disable).
- P03 (Sleep Mode Time): Set the idle time before entering sleep mode (1-120 minutes, 'oFF' to disable).
- P04 (One-Touch Enhanced Temperature Retention Time): Set the duration for the temperature boost (60-180 seconds).
- P05 (Sound Status): Turn the machine's buzzer sound on or off.
- P06 (Heating Core Temperature Calibration Parameter): Adjust calibration parameters (35.0-80.0) for precise temperature calibration.
5.5. Temperature Calibration
This machine supports precise single-point temperature calibration of the heating core.
- Before entering calibration, note the current operating temperature setting.
- Select P06 in the setting mode to enter calibration parameter modification.
- Use a professional soldering iron temperature measuring instrument to measure the actual temperature of the heating element.
- While in P06, adjust the calibration parameters using the encoder knob. The host will beep twice to confirm adjustments.
- Compare the measured temperature with the set temperature:
- If measured temperature > set temperature, increase calibration parameters.
- If measured temperature < set temperature, decrease calibration parameters.
- Continue adjusting until the measured temperature matches the set temperature. Press and hold the encoder to save and exit.
6. Maintenance
6.1. Soldering Iron Tip Care
- Keep Clean: Always keep the soldering iron tip clean. Use the provided copper ball and cleaning sponge to remove excess solder and residue.
- Maintain with Solder: After use, tin the tip with a small amount of fresh solder to prevent oxidation and extend its lifespan.
- Avoid High Temperatures: Do not set the temperature too high for extended periods. Optimal welding temperature is generally between 350-380°C. High temperatures accelerate tip aging. Utilize the temperature enhancement and standby functions to manage tip temperature effectively.
- Replacing Tips: When replacing a soldering iron tip, especially if it's from a different manufacturer, ensure you select the corresponding model and recalibrate the temperature (refer to Section 5.5).

7. Troubleshooting
7.1. Error Codes
The soldering station may display error codes to indicate specific issues:
- 'Err' or 'SE': Indicates that the handle or heating element is offline, or the heating element has an open circuit fault.
- 'O.CP': Indicates a short circuit fault in the heating element. The host will sound an alarm.
- 'OPP': Indicates an abnormal heating fault of the heating element. The host will sound an alarm.

7.2. Solutions
- For 'Err' or 'SE': Check if the handle cable and heating element are properly plugged in. Inspect the handle and soldering iron tip for any visible damage. If necessary, remove and inspect or replace the heating element.
- For 'O.CP' or 'OPP': Remove the heating element and inspect it. Also, check the host unit for any issues. If the problem persists, the heating element may need to be replaced.
- New Heating Element Break-in: When using a new heating element for the first time, especially a domestic one, it needs a break-in period. Initial temperature fluctuations or errors are normal. Adjust the temperature to 350°C and let it age for approximately 3-10 minutes before normal use.
8. Safety Precautions
To prevent electric shock, personal injury, fire, or explosion, always adhere to the following safety guidelines:
- Electrical Safety: Ensure the power cord is connected to a correct and properly grounded power source before use. Do not operate on live electrical components.
- Handling Hot Components: The soldering iron tip and heating element become extremely hot during operation. Always use the included anti-scald pad when quickly changing the welding tip to prevent burns.
- Proper Storage: When not in use, always place the soldering iron handle on the designated soldering iron stand to prevent fire hazards.
- Supervision: Do not leave the equipment unattended when powered on. Always turn off the power when not in use.
- Unauthorized Modifications: Non-professionals are not allowed to disassemble or maintain this product. Do not use unapproved controllers or handles for operation.
- Grounding for Welding: When performing important welding work, ensure your power outlet is connected to a ground wire. If necessary, connect the independent ground wire interface at the end of the welding station to a reliable ground source.
- Incompatible Handles: Do not attempt to insert handles from other manufacturers into the welding station's main unit. Incompatible handles may cause vibration and wake-up function failure, hardware damage, loss of temperature control, and potentially serious consequences such as fires.
