Take up the iron- handle
Note: * The soldering iron must be placed at the soldering iron station. And only in this state, the
soldering station can sleep automatically when up to the setting time.
* The solder station will not into sleep when the sleeping time is 000. And the solder will sleep at
once when the setting sleeping time is 001 and the handle is placed at the solder holder.
2) Off time setting
If the station isn’t resumed during the sleeping time, the power supply will be shut off automatically, and
the station will stop working. Turn on the power switch to resume working.

off immediately after it comes into sleep state.
3) Sleeping temperature setting
a) In the process of “sleeping temperature” setting, the display shows “sleep” and “set temp” ,
and then press “△”or “▽”key to change the sleeping temperature
b) The range of sleeping temperature is from 50℃to 250℃
c) In the sleeping state, if the sleeping temperature is less than the setting temperature of the
soldering station, the temperature will fall down to the sleeping temperature. Otherwise, down
to the soldering station’s setting temperature
Such as: If the setting sleeping temperature is 200℃and the setting work temperature is 280℃, in
sleeping state, the iron’s temperature will fall down to 200℃.
If the setting sleeping temperature is 200℃and the setting work temperature is 150℃, in
sleeping state, the iron’s temperature in sleeping will fall down to 150℃.
4) Up temp setting
a) In the up temp setting state, the display shows “Up Temp”(refer to the picture) and press “△”
or “▽” key to change the temperature. Once difference in temperature between the real
temperature (Real Temp) and the setting temperature (set temp) is bigger than the up temp,
the soldering station will alarm when in the alarming mode

5) Down temp setting
a) In the down temp setting, the display shows “Down Temp”(refer to the picture) and press “△”
or “▽” key to change the temperature. Once difference in temperature between the real
temperature (Real Temp) and the setting temperature (set temp) is bigger than the Down
Temp, the soldering station will alarm when in the alarming mode
b) The range of the “Down Temp” is from 0℃to 99℃.
4.4 Calibrating the temperature
1) The soldering iron should be recalibrated every time after replacing the iron, the heating element
or the tip
2) This device adopts digital calibration mode and input the revision value by pressing key
3) Methods of recalibrating the temperature:
I. Set the temperature of the soldering station to a certain value
II. When the temperature stabilizes, measure the tip’s temperature with thermometer
and write down the values
III. Press “*” key unlooseningly and then press the “△”and“▽”keys simultaneously, the
soldering station enters the temperature calibration mode and LCD displays “Cal
Temp”.
Calibrating temperature
4) The number is not flash and press “△” or “▽” key to record the temperature tested by the
thermometer to the soldering station. After that, press “*” key and the process of temperature
calibration is end
5) If the temperature still has some departure, you can repeat calibration in according with the above
steps.
Note: * Suggest using the 191 or 192 thermometer to measure the tip’s temperature.
* If the soldering station is locked by the password, it will not be able to calibrate the tip
temperature and you must input the correct password.

5. Use / care and maintenance
5.1 Select a correct tip
1. Select a tip which maximizes contacting area between the tip and solder joint. Maximizing contact
area transfers the heat more efficient, helping the operators to produce high quality solder joints
quickly
2. Select a tip with transferring the heat to the solder joint well. A tip with shorter length can control
more precise. And the Longer or angled tip may be needed for soldering densely populated boards.
Tips
5.2 Tip’s using caution
1) High soldering temperature can degrade the function of the tip and use the tip with the lowest
possible soldering temperature. The excellent thermal recovery characteristics ensure efficient
and effective soldering event at low temperatures. This also can protect the sensitive components
from thermal damage
2) When using the soldering iron continuously, be sure to loosen the tip and remove all oxides on the
tip at least once a week. This helps prevent reducing of the tip temperature

10
3) Never keep the soldering iron at high temperature for a long time when not using,. Because the tip
will be covered with oxide that can greatly reduce the tip's heat conductivity
4) Wipe the tip and coat it with fresh solder after using. This helps to prevent tip oxidation
5) Clean the tip regularly with a cleaning sponge. Oxides and carbides deriving from the solder and the
flux can form impurities on the tip. These impurities can result in defective joints or reduce the
heating conductivity of the tip
6) Use fine tips only when necessary. The plating on fine tips is less durable than the plating of the
blunter tips
7) Do not use the tip as a detecting tool. Bending the tip can cause the plating to crack and shorten
the tip’s life
8) Use the minimum activation flux necessary to do the job. Higher activation flux is more corrosive to
the tip plating
9) Don’t apply pressure to the tip. More pressure does not equal more heat. To improve heat transfer,
use solder to form a thermal bridge between the tip and the solder joint
5.3 Check and clean the tip
1) Set the temperature to 250℃
2) When the temperature stabilizes, clean the tip with the cleaning sponge and check the condition of
the tip
3) If there is black oxide on the solder-plated portion of the tip, coat new solder (containing flux) and
then wipe the tip on the cleaning sponge. Repeat until the oxide is completely removed and then
coat with the new solder
4) If the tip is deformed or heavily eroded, replace it with a new one
5.4 Renew a detinned tip
Why does a detinned tip fail to work?
A detinned tip is one not wetted with solder. This exposes the plating to oxidation and degrades the heat
transfer efficiency of the tip.
Detinning is caused by:
a. Failure to keep the tip coating with fresh solder while not in using
b. High temperatures
c. Insufficient melting in soldering operations
d. Wiping the tip on dirty or dry sponges or rags (It should use a clean, wet, industrial grade, sulfur-
free sponge)
e. There are impurities in the solder, iron plating, or on the surfaces to be soldered
Renew a detinned tip
a) Remove the tip from the handle after the tip cooling down
b) Remove the dirty and oxides from the tip with 80-grit abrasive polyurethane foam stock or a 100-
grit emery
c) Wrap the stannum including rosin (φ0.8mm or larger) around the newly exposed iron surface,
insert the tip into the handle, and turn on the power switch
Note: *Never file the tip to remove oxide.
*Proper daily care can prevent the tip from detinned.

5.6.2 Checking the heating element
Pull out the plug and measure the resistance value between the pins of the connecting plug when the
heating element cooling down to the room temperature.
1) If the values of ‘a’ and ‘b’ are different from the values in the following table, replace the heating
element or sensor or cord assembly. Refer to the following steps
2) If the value of ‘c’is over the below value, remove lightly the oxidation in the joint part of the tip and
the heat element with sandpaper or steel wool
Note: * When checking b and c items in the table, the soldering iron must be equipped with tip.
* The pin’s sequence above picture is same with the socket of soldering station and in the
socket of the soldering iron handle after disconnecting the handle. Please find the
corresponding pins when check the sensor or the heating element of the handle.
5.6.3 Replace the heating element
1. Cut off the strap connecting the heating element and the handle cord and pull out the sensor’s
pin and desolder each wire of handle cord from heating element
2. Remove the broken heating element and replace a new one
3. Solder each wire of handle cord to its pin according to connection way of desoldering. Connect
black and white wires to two heating pins of the heating element and connect the grounding
wire (shield cord) to the grounding pin
4. Put the sensor pin on the red wire into the sensor pin jack of the heating element
5. After replacing the heating element, test heating element according to the following “5.5.4 test
the heating element” and install it after confirming it is well
6. Tie up the heating element and the handle cord with the strap
7. Put the heating element into handle according to the opposite order of disassembling, and the
heating element must be put into bottom. The bulge of the sensor pin jack should be put into
