5. Setup

5.1 Initial Inspection

Upon unpacking, inspect all components for any signs of damage. Ensure all listed package contents are present.

5.2 Removing Transit Screws

Before initial use, locate and remove any transit screws from the bottom of the main unit. These screws are typically installed to secure internal components, such as the air pump, during shipping. Failure to remove them may cause excessive vibration or damage during operation.

5.3 Connecting Components

1. Connect the soldering iron cable to the designated socket on the main unit.
2. Place the soldering iron into its stand. Ensure the stand is stable and includes the cleaning sponge and brass tip cleaner.
3. Connect the hot air gun cable to its designated socket on the main unit.
4. Attach the desired hot air nozzle to the hot air gun.
5. Plug the power cord into the main unit and then into a standard 110V AC power outlet.

6. Operating Instructions

6.1 Powering On and Temperature Unit Conversion

Press the main power switch to turn on the unit. The digital displays will illuminate. To switch between Celsius (°C) and Fahrenheit (°F), press and hold both the UP and DOWN temperature adjustment buttons simultaneously for either the soldering iron or hot air rework station while the unit is on.

6.2 Soldering Iron Operation

Figure 6.1: Demonstrates the soldering iron in operation, showing the temperature display and the process of soldering components onto a circuit board.

1. Turn on the 'WORK' switch for the soldering iron section.
2. Use the 'UP' and 'DOWN' buttons to set the desired temperature. The soldering iron features PID temperature control, ensuring rapid heating and stable temperature maintenance within the range of 212°F to 896°F (100°C to 480°C).
3. Allow the iron to reach the set temperature. The display will show the current temperature.
4. Apply solder to the joint. The iron's precise temperature control facilitates efficient soldering.
5. When not in use, place the soldering iron back into its stand. The iron will automatically enter sleep mode and cool down after 10 minutes of inactivity, extending the life of the heating element.

6.3 Hot Air Rework Station Operation

Figure 6.2: Illustrates the hot air rework station in use, showing the temperature display and the application of hot air for desoldering or rework tasks on a circuit board.

1. Turn on the 'WORK' switch for the rework station section.
2. Use the 'UP' and 'DOWN' buttons to set the desired air temperature. The hot air gun can be adjusted from 212°F to 932°F (100°C to 500°C).
3. Adjust the air volume using the dedicated adjustment button.
4. Allow the hot air gun to reach the set temperature.
5. Direct the hot air flow onto the component to be reworked or desoldered.
6. After use, place the hot air gun back into its holder. The unit features an automatic cooling system that will continue to blow air until the nozzle temperature drops to a safe level, preventing damage to the heating element and ensuring safety.

7. Maintenance

7.1 Soldering Tip Maintenance

• Always tin the soldering tip with a small amount of solder before and after use to prevent oxidation.
• Clean the tip frequently using the brass tip cleaner or a damp sponge.
• Replace tips when they become excessively worn or corroded to maintain optimal performance.

7.2 General Cleaning

• Ensure the unit is unplugged and completely cool before cleaning.
• Wipe the main unit and handles with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Keep the air vents clear of dust and debris to ensure proper airflow and cooling.

8. Troubleshooting

• Unit does not power on: Check the power cord connection and the power outlet. Ensure the main power switch is in the 'ON' position.
• Soldering iron or hot air gun not heating: Verify that the respective 'WORK' switch is engaged and the temperature is set above the ambient temperature. Check cable connections.
• Inconsistent temperature: Ensure the soldering tip is clean and properly tinned. For the hot air gun, check for any obstructions in the nozzle or air intake. The unit features PID control for stability, but extreme environmental conditions can affect performance.
• Hot air gun does not enter standby/cool down: The hot air gun is designed with an automatic cooling system that activates when placed in its holder. If this function does not engage, ensure the holder sensor is clean and unobstructed. If the issue persists, contact customer support.
• Excessive vibration or noise: Ensure all transit screws were removed during setup. If the issue persists, internal components may require inspection by a qualified technician.
• Temperature offset adjustment: If you suspect the displayed temperature is inaccurate, the unit allows for temperature offset adjustment. Refer to the detailed instructions in the full user manual for specific steps on how to calibrate the temperature offset.
