Setup
- Unpack: Carefully remove all components from the packaging.
- Connect Soldering Iron: Insert the soldering iron handle's connector firmly into the designated port on the soldering station host.
- Power Source:
- Battery Power: Attach a compatible 18V/20V DEWALT, Milwaukee, or MAKITA battery to the base of the soldering station. Ensure it clicks securely into place.
- DC Port Power: Alternatively, connect a 20V DC/3.5A power adapter (not included) to the DC input port on the side of the station.
Warning: Do NOT use both battery and DC port power simultaneously. This can damage the unit and pose a safety risk.
- Place Iron in Stand: Position the soldering iron in the heat-resistant holster ring when not in active use. The station also features portable solder wire storage slots.
Operating Instructions
- Power On: Flip the master power switch to the "ON" position. The LED Nixie display will illuminate.
- Adjust Temperature: Use the adjustment knob to set the desired temperature. The temperature range is 200°C-480°C (392°F-896°F). Turn the knob clockwise to increase temperature and counter-clockwise to decrease.
- Fahrenheit/Celsius Conversion: Press the temperature adjustment knob briefly to switch between Fahrenheit (°F) and Celsius (°C) display modes.
- Soldering: Once the desired temperature is reached (indicated by the display), you can begin soldering. Apply solder to the joint, not directly to the iron tip.
- Sleep Mode: If the soldering iron is not used for a set period (adjustable from 1-8 minutes), it will automatically enter sleep mode to protect user security, increase battery life, and extend heating element life. The display will show "F0X" (where X is the set time).
- Wake from Sleep Mode: Gently shake the soldering iron to wake it from sleep mode. It will quickly return to the previously set temperature.
- Stand-by Mode: If the soldering iron remains in sleep mode for an extended period, it will enter stand-by mode. The display will show "L0X" (where X is the set time).
- Wake from Stand-by Mode: Turn the temperature adjustment knob to wake the station from stand-by mode.
- Digital Temperature Calibration: The station supports digital temperature calibration for precise temperature control. Refer to the specific instructions for your calibration device.
- Power Off: When finished, turn the master power switch to the "OFF" position and disconnect the battery or DC power supply. Allow the iron to cool completely before storing.

Maintenance
- Tip Cleaning: Regularly clean the soldering iron tip using a tip cleaner (e.g., brass wool or a damp sponge). This increases the life of the iron tip and ensures better solder joints.
- Storage: Store the soldering station and iron in a dry, safe place when not in use. Ensure the iron is completely cool before storage.
- General Cleaning: Wipe the station and iron handle with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Tip Replacement: Replace worn or damaged soldering tips as needed. Ensure the replacement tips are compatible with your soldering iron.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Station does not power on. | No battery or DC power connected; battery depleted; power switch off. | Ensure a charged, compatible battery is connected or DC power adapter is plugged in. Check master power switch. |
| Soldering iron not heating up. | Incorrect temperature setting; iron not properly connected; unit in sleep/stand-by mode. | Adjust temperature knob. Check iron connection. Wake from sleep/stand-by mode by shaking the iron or turning the knob. |
| Poor solder joints. | Dirty or oxidized tip; incorrect temperature; old/poor quality solder. | Clean the soldering tip. Adjust temperature. Use fresh, good quality solder. |
| Temperature display shows "F0X" or "L0X". | Unit is in Sleep Mode (F0X) or Stand-by Mode (L0X). | Shake the iron to exit Sleep Mode. Turn the temperature knob to exit Stand-by Mode. |
User Tips
- Battery Compatibility: Always double-check that your 18V/20V battery is from one of the compatible brands (DEWALT, Milwaukee, MAKITA) to ensure proper function and safety.
- Temperature Control: For delicate electronics, start with a lower temperature and gradually increase it until the solder flows smoothly. For larger components or wires, a higher temperature might be necessary.
- Tip Selection: Use the appropriate soldering tip for the task. Finer tips are good for small components, while broader tips are better for larger joints or desoldering.
- Pre-tinning: Always pre-tin your soldering iron tip with a small amount of solder before use to improve heat transfer and prevent oxidation.
