4. Setup
Follow these steps to set up your 938BD-III station:
- Unpacking: Carefully remove all components from the packaging. Verify that all items listed in the 'What's in the Box' section are present.
- Placement: Place the main unit on a stable, heat-resistant, and non-flammable surface. Ensure adequate ventilation around the unit.
- Connect Soldering Iron: Plug the soldering iron cable into the designated port on the front panel of the main unit. Secure it if a locking mechanism is present.
- Connect Hot Air Gun: Plug the hot air gun cable into its designated port on the front panel.
- Install Hot Air Nozzle: Select the appropriate nozzle for your task and securely attach it to the hot air gun.
- Power Connection: Connect the power cord to the main unit and then to a grounded electrical outlet.
- Accessories: Place the soldering iron stand, cleaning sponge, and metal cleaning ball in their respective positions for easy access during operation.
5. Operating Instructions
5.1 General Operation
- Turn on the main power switch located on the front or side of the unit. The digital display will illuminate.
- Use the dedicated control knobs or buttons for the hot air gun and soldering iron to adjust temperature and airflow (for hot air).
- Allow the tools to reach the set temperature before beginning work.
5.2 Temperature Calibration
Both the hot air gun and soldering iron can be calibrated for accurate temperature readings, improving work efficiency.
Digital Temperature Calibration: This image demonstrates the process of calibrating the temperature. First, simultaneously press the '+' and '-' buttons (1). Then, measure the current actual temperature using an external thermometer (2). Finally, adjust the displayed temperature to match the measured temperature (3).
5.3 Auto Sleep Function
The soldering iron features an intelligent dormancy function to save energy and prolong tip life.
10-Minute Auto Sleep: If the soldering station detects no usage or movement for more than 10 minutes, the soldering iron will automatically enter sleep mode (indicated by 'SLP' on the display). To reactivate, simply pick up the soldering iron from its stand.
6. Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your soldering station.
- Soldering Tip Cleaning: Always clean the soldering iron tip before and after use. Use the provided metal cleaning ball or a damp cleaning sponge.
- Sponge Usage: Dampen the cleaning sponge with distilled water before use. Wring out excess water to prevent thermal shock to the tip.
- Tip Tinning: After cleaning, re-tin the soldering iron tip with a small amount of solder to prevent oxidation.
- Nozzle Cleaning: Periodically clean the hot air gun nozzles to remove flux residue and ensure unobstructed airflow.
- General Cleaning: Keep the main unit and tools free from dust and debris. Use a soft, dry cloth for cleaning. Do not use abrasive cleaners or solvents.
- Storage: Store the unit in a dry, dust-free environment when not in use. Ensure all components are cool before storage.
Soldering Iron Stand and Cleaning Accessories: The stand provides a safe place for the soldering iron and includes compartments for storing various soldering iron tips. It also features a metal cleaning ball for dry tip cleaning and a cleaning sponge for wet cleaning, both essential for maintaining tip longevity and performance.
