3. Safety Information

Always observe the following safety precautions when operating the LUKEY 702 soldering station to prevent injury or damage to the equipment:

• Electrical Safety: Ensure the power supply matches the specified voltage (220V-240V). Always connect the unit to a grounded outlet. Do not operate with wet hands or in damp environments.
• Heat Hazard: The soldering iron tip and hot air nozzle reach very high temperatures. Avoid direct contact with skin or flammable materials. Allow components to cool completely before handling.
• Fume Ventilation: Soldering produces fumes that can be harmful. Always work in a well-ventilated area or use a fume extractor.
• ESD Protection: The unit features antistatic protection. However, always take additional ESD precautions when working with sensitive electronic components.
• Proper Use: Use the station only for its intended purpose. Do not modify the unit or use non-original parts.
• Storage: Store the unit in a dry, safe place away from children and unauthorized users.

4. Setup Guide

Follow these steps to set up your LUKEY 702 soldering station:

1. Unpack: Carefully remove all components from the packaging and inspect for any damage.
2. Placement: Place the main unit on a stable, heat-resistant, and non-flammable surface, ensuring adequate ventilation around the unit.
3. Connect Hot Air Gun: Connect the hot air gun handle cable to the designated port on the front panel of the main unit. Ensure it is securely fastened.
4. Connect Soldering Iron: Connect the soldering iron handle cable to its respective port on the front panel. Place the soldering iron in its stand.
5. Attach Nozzle: Select the appropriate hot air nozzle for your task and securely attach it to the hot air gun.
6. Power Connection: Connect the power cord to the main unit's power input on the rear, then plug the US plug into a grounded 220V-240V AC outlet.

5.1. Hot Air Rework Station Operation

1. Power On: Press the 'HOT AIR' power button on the front panel. The digital display will illuminate.
2. Set Temperature: Use the 'TEMP' up/down arrow buttons for the hot air section to set the desired temperature (range: 100 - 480 ℃).
3. Adjust Airflow: Rotate the 'AIR' knob to adjust the airflow speed. Start with a lower setting and increase as needed. The maximum airflow is 120 l/min.
4. Operation: Once the set temperature is reached, the hot air gun is ready for use. Always hold the hot air gun by its handle and direct the hot air away from yourself and flammable materials.
5. Cooling Function: After use, place the hot air gun back into its holder. The unit features a unique cooling function: the fan will continue to operate until the airwave temperature falls below 50 ℃, automatically turning off to extend the lifespan of the handle and heating element.

5.2. Electric Soldering Iron Operation

1. Power On: Press the 'SOLDER' power button on the front panel. The digital display will show the current temperature.
2. Set Temperature: Use the 'TEMP' up/down arrow buttons for the soldering iron section to set the desired temperature (range: 200 - 480 ℃).
3. Tinning the Tip: Before first use or after cleaning, tin the soldering iron tip by applying a small amount of solder. This helps with heat transfer and prevents oxidation.
4. Soldering: Apply the heated tip to the joint, then feed solder onto the joint, not directly onto the tip. Allow the solder to flow evenly.
5. Cleaning the Tip: Regularly clean the soldering iron tip using the included sponge (dampened with water) or copper wire cleaner to remove excess solder and oxidation.

6. Maintenance

Proper maintenance ensures the longevity and optimal performance of your LUKEY 702 soldering station.

• Soldering Iron Tip Care: Keep tips clean and tinned. Replace tips when they become pitted or excessively oxidized. Use only lead-free solder if working with lead-free components.
• Hot Air Nozzle Cleaning: Periodically inspect and clean hot air nozzles to ensure unobstructed airflow.
• Sponge Maintenance: Keep the cleaning sponge damp (not soaking wet) during use. Replace the sponge when it becomes worn or heavily soiled.
• General Cleaning: Keep the main unit and handles clean and free of dust and debris. Use a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Power Off: Always turn off the unit and unplug it from the power source when not in use or before performing any maintenance.
