INSTRUCTION MANUAL FOR LF-399D & LF-389D TEMPERATURE CONTROLLED SOLDERING STATION
INTRODUCTION Thank you for purchasing our 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.
REMEMBER UNPLUG IN THE POWER CORD ◆ The station must be switched off and the power cord must be unplug in before replacing the fuse in the P.C.B. Caution: Soldering irons operate at high temperatures and can easily burn the skins and/or objects. Do not touch the tip and heater at any time and to keep it a safety distance from flammable materials while the unit is on or while being cooling.
OPERATING INSTRUCTIONS Caution: Check carefully for any damage during transportation and ensure that the working voltage matches your power supply before plugging in the station. 1. Ensure that the base unit power switch is in the “OFF” position. 2. Plug in AC power cord and turn “Mains power switch” to “ON” position then LED display will be ON and show the temperature value. 3.
PARAMETER SETTING: 1. Press “SET” key and hold for at least 4 seconds until display shown “— — —” sign then release the “SET” key. The sign “— — —” starts to flash and reminding the user to input the mode lock password “010” (fixed). If the user inputs the same number as “010”, the unit will enter the modes selection procedure, otherwise, the unit will be back from the current mode automatically. 2. After the unit enters the Modes selection, the LED will display “F-0”and flash.
Example for temperature correction: The current set temperature value is 200℃, but the actual temperature is only 190℃. So it needs to correct by +10℃. Correction method: if the current correction value is 00 or -00; then change it to 10. If the current correction value is -20, then change it to -10. If the current correction value is 20, then change it to 30. 5.
CARE OF TIPS Ca Caution: The soldering iron can reach very high temperature. Be sure to turn the unit off prior to carrying out any maintenance or trouble shooting steps listed below. IMPORTANT - Remove the tip and clean after every usage or at least once a week. Remove any loose build up in the tip retaining assembly to prevent tip freezing. The solder tips supplied are iron clad pure copper and if used properly will give a long life. 1.
tip and screw back the knurled nut barrel assembly using only firm hand pressure to tighten. Pliers should only be used to tighten the nut to avoid burning your fingers, but care should be taken not to over-tighten as this would damage the element.
