07
When the soldering handle is picked up
from the holder, the iron tip will
automatically heat to the selected
temperature. Then start operating
Change the temperature setting (90°C to 450°C)
Change fast temperature settings
Working mode
Through the temperature setting interface: Change standby temperature (temperature
can be customized)
Change standby delay (standby delay time
can be customized)
Through the standby setting interface：
When the soldering handle is placed in
the handle holder, the host will
automatically enter the standby mode
and the temperature will automatically
drop to the preset standby temperature.

06 Precautions

Precautions for soldering station
Precautions for soldering iron tip
To avoid damage to the soldering station and consider safety of the
working environment, the following matters shall be observed:
This product uses a three wire grounding plug, which must be inserted into a three hole
grounding socket. Do not change the plug or use an ungrounded three head adapter to
make the grounding poor. To lengthen the wire, use a grounded three wire power cord.
Please do not make any change to the soldering station without authorization.
When replacing parts, the original factory parts shall be used.
Please do not wet the station. Do not use the station nor pull the power cord
when hands are wet.
There is smoke during soldering, good ventilation facilities should be available
in the working environment.
Please do not do anything that may harm the product when using the station.
Please place the station in a dry environment when it’s not in use for a long time.
When turning on the switch, the soldering iron tip is in a high
temperature state. In view of the possibility of burns or fire
caused by abuse, please strictly abide by the following matters:
Please avoid the abuse of this station and use this product according to the
operating instructions.
Do not touch the metal part near the soldering iron tip.
Do not use the iron tip near flammable objects.
Inform other personnel that the iron tip is very easy to burn and may cause dangerous
accidents. The power shall be turned off when not using.
When replacing the soldering iron tip, do not touch it directly by hand to prevent scalding.
Do not knock the soldering iron on the workbench to remove the residual flux, which
may seriously damage the soldering iron.
Do not use the soldering iron tip for work other than soldering.
This product has anti-static measures.
Please be sure to use it grounded.

07 Use and maintenance of
soldering iron tip
09
Note: do not use a file to remove the oxide on the iron tip
1. Set the temperature at 250 degrees Celsius (482 degrees Fahrenheit).
2. After the temperature is stable, clean the iron tip with a cleaning sponge and
check the state of the soldering iron.
3. If there is black oxide, plate with a new tin layer, and then wipe with a cleaning sponge.
Cleaning like that repeatedly until the oxide is completely removed, and then plate with
a new tin layer.
4. If the soldering iron tip is deformed or rusted, replace with a new soldering iron tip.
Use of soldering iron tip
Soldering iron
tip temperature
Too high temperature will weaken the function of tip, choose the
temperature as low as possible. This tip has an excellent temperature
resilience, and support soldering at the lower temperature, which can
protect components that are sensitive to temperature.
Cleaning
Clean the soldering iron tip regularly with a cleaning sponge. After soldering,
the oxides and carbides derived from the residual flux will damage the tip,
cause soldering errors or reduce the thermal conductivity of the tip.
If using the tip continuously for a long time, please disassemble the tip once a
week to remove the oxide to prevent it from being damaged and reduce the
temperature.
When not in use
When not in use, do not keep the tip at high temperature for a long time,
or the flux on the tip will be converted into oxide and greatly reduce the
heat conduction ability.
After use After use, the tip shall be wiped clean and plated with a new tin layer
to prevent oxidation.
Tin planting failure may be caused by:
1. When the soldering iron is idle, it is not covered with new tin layer.
2. The soldering iron tip is at high temperature.
3. Insufficient melting during soldering.
4. Clean the tip on a dry or unclean sponge or cloth. [The clean and moist industrial grade
sulfur-free sponge should be used]
5. The solder or iron coating is impure, or the soldering surface is not clean.

08 After Sales

Note: Proper daily maintenance will effectively improve the
service life of the soldering iron tip
How to prolong the service life of soldering iron tip?
Soak with fresh solder after each use to prevent the oxidation and prolong
its service life.
Apply the temperature as low as possible to fulfill the work, low temperature
can not only reduce the oxidation of the iron tip, but also easy to solder.
Use a thin iron tip only in necessary, the coating of a thin iron tip is not as durable
as that of a thick iron tip.
Do not use the soldering tip as a detection tool, bending of the soldering tip
will lead to the rupture of the coating and shorten the service life.
Use less active rosin flux, because the high content of active rosin will accelerate
the corrosion of iron tip coating.
When not in use or stop soldering, put the handle into the handle holder or turn
off the power in time.
Do not exert heavy pressure on the soldering tip, higher pressure does not mean
fast heat transfer. In order to provide heat transfer, the solder must be melted to
form a heat transfer solder bridge between the soldering tip and the solder joint.
