Note: The station has many working modes and the default mode is six.

If sleeping and working mode are selected, and the soldering iron is not used for 20 minutes, the
power to the heating element will be decreased, and the display shows . This state is
sleeping mode. When the station is in sleeping mode, the tip temperature will decrease to 200℃
(if the set temperature is more than or equal to 200℃) or 50℃(if the set temperature is less than
200℃) and remain the temperature until resuming the station.
To resume soldering, there are several ways as follows:
1. Cycle the power switch OFF, then ON.
2. Hit any button.
3. Take up the iron-handpiece.
If the soldering station is not resumed more than 40 minutes after it comes to sleep, the power
supply will be shut off automatically, and the display window will not show anything.
To Select The Correct Tip For A SolderApplication
1. Pick a tip that maximizes contact area between the tip and solder Joint. Maximizing contact
area gives the most efficient heat transfer, allowing operators to produce high quality solder
joints quickly.
2. Pick a tip that allows good access to the solder joint. Shorter tip lengths allow more precise
control. Longer or angled may be needed for soldering densely populated boards.
Calibrating the Iron Temperature
The Soldering Iron should be recalibrated after changing the iron or replacing the heating
element or tip.
Method of recalibrating temperature: Use the thermometer to calibrate.
1. Set the unit’s temperature to a certain value.
2. When the temperature stabilizes, measure the tip’s temperature with thermometer and write
down the reading.
3. Press “＊” button not loose and press the “▲”and “▼” buttons simultaneously, the
soldering station enters into calibration mode.
4. At the moment, the 100’s digit of LED display temperature is flashing. Press the “▲” and
“▼” buttons to select the value and press the “＊” button to select the digit. Press “＊”
button after inputting the reading. Here, the calibration operation has finished.

5. If the temperature still has deflection, you can repeat calibration in accordance with above
steps.
* We recommend using the 191/192 thermometer for measuring the tip temperature.
* If the unit is locked by password, it will not be able to calibrate and you must input the right password.
Tip Care and Use
․Tip Temperature
․Cleaning
․When not in use
․After use
High soldering temperatures can degrade the tip.
Use the lowest possible soldering temperature. The
excellent thermal recovery characteristics ensure
efficient and effective soldering event at low
temperatures. This also protects the soldered items
from thermal damage.
Clean the tip regularly with a cleaning sponge, as
oxides and carbides from the solder and flux can
form impurities on the tip. These impurities can
result in defective joints or reduce the tip's
heat conductivity.
When using the soldering iron continuously, be sure
to loosen the tip and remove all oxides at least once
a week. This helps prevent seizure and reduction of
the tip temperature.
Never leave the soldering iron sitting at high
temperature for long periods of time, as the tip's
solder plating will become covered with oxide,
which can greatly reduce the tip's heat conductivity.
Wipe the tip and coat the tip with fresh solder.
This helps to prevent tip oxidatio
Maintenance
Inspect 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.

!
Caution: Never file the tip to
remove oxide
Why A” Detinned” Tip fails 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 :
To Restore A Detinned tip
Extending Tip Life
3. If there is black oxide on the solder-plated
portion of the tip, apply new solder ( containing
flux ) and wipe the tip on the cleaning sponge.
Repeat until the oxide is completely remove.
Coat with new solder. The solder protects the
tip from oxidation and prolongs the life of the
tip.
4. If the tip is deformed or heavily eroded, replace
it with a new one.
a. Failure to keep the tip covered with fresh
solder during idling periods.
b. High tip temperatures.
c. Lack of sufficient flux in soldering
operations.
d. Wiping the tip on dirty or dry sponges and
rags.( Always use a clean, wet, industrial
grade, sulfur-free sponge.)
e. Impurities in the solder, iron plating ,or on
the surfaces to be soldered
1. Remove the tip from the solder handle and
allow the tip to cool down.
2. Remove scale and oxides from the tinned area
of the tip with 80-grit abrasive polyurethane
foam stock or a 100-grit emery cloth.
3. Wrap rosin core solder (0.031” diameter or
larger) around the newly exposed iron surface,
insert the tip into the handle, and turn on the
system.
NOTE: Detinned tips are preventable with proper
daily care!
1. Tin the tip before and after each use. This
protects the tip from oxidizing, and prolongs
the tip's life.
2. Do the job at the lowest temperature. Lower
temperatures decrease tip oxidation and are
easier on the components being joined.

3. Use fine point tips only when necessary. The
plating on fine precision tips is less durable
than the plating on blunter tips.
4. Do not use the tip as a prying tool. Bending the
tip can cause the plating to crack, shortening tip
life.
5. Use the minimum activation flux necessary to
do the job. Higher activation flux is more
corrosive to the tip plating.
6. Extend tip life by switching the system off
when not in use.
7. 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.
Error Messages
Various error messages will be display when there is a problem with the unit. If the following
message is displayed, see the trouble shooting guide.
Sensor Error
Note
Heater Error
If there is a possibility of a failure in the sensor or
anywhere in the sensor circuit, will be
displayed and power to the soldering iron will be
cut off.
If power is being sent to soldering iron and the tip
temperature goes below the setting temperature
about 80℃, the temperature display will flash.
Draw your attention to this.
If power can’t be sent to soldering iron, the display
window will show . This indicates the
possibility of a heater malfunction.
