INSTRUCTION MANUAL FOR LF-389D TEMPERATURE CONTROLLED SOLDERING STATION INTRODUCTION Thank you for purchasing the LF-389D soldering station – the best solution for your
soldering equipment needs! We believe that you will be more than satisfied with many features and the versatility of your new soldering station. Please carefully read the instruction manual prior to operation to maximize the advantages of using your new soldering station. WARNING: This appliance is not intended for use by children or other persons without assistance or supervision if their physical, sensory or mental capabilities prevent them from using it safely.
has been designed to meet the present and future soldering needs of the electronic production industry, hobbyist and students. The LF-389D rated current has 220-240Vac, 50Hz or 100-120Vac, 60Hz for option. Both incorporate electronic circuitry which enables the user to adjust the temperature from 150℃(392℉) through 480℃(896℉) without changing the tip. The temperature is maintained to within ±5℃(9℉) of its idling temperature through the use of its PTC characteristic.
be flashed on and off to maintain the set temperature. The unit now is ready for use. SPECIFICATIONS: Model Input Output Fuse (Fast type) LF-389D 220-240Vac 50Hz 100-120Vac 60Hz 60W 0.
then means the unit will be under the password status. Press “SET” key once to finish password setting and the unit will backup mode, the user can continue set other modes or back from the setting mode. 4. Temperature Correction Setting: Press “SET” key once when the LED displays “F-2” and flashes that the unit enters the Temperature Correction Mode. At this moment, the LED displays preset correction value.
The working temperature of solder is detailed below and can vary from manufacture to manufacture. Melting point Normal operation Production line operation 220℃(428℉) 300-360℃ (572-680℉) 360-410℃ (680-770℉) IMPORTANT: The temperature above 410℃ (770℉) is not recommended for normal soldering functions, but can be used for short periods of time when high temperatures are required. Please note that the lead free solder alloys require a higher soldering temperature which shortens tip life.
NEW TIP Used according to the following procedures if a new tip were installed at any time, it will give the tip much longer life. 1. Turn “Mains power switch” to “ON” position and set temperature to 250℃ (392℉). 2. Flood the tinned surfaces with resin-core solder when temperature reaches 250℃ (392℉). 3. Set at desired temperature after warming for few minutes. 4. The iron will be ready for use once it reaches the preset temperature. IMPORTANT - Remove and clean the tip daily.
