Precautions
These symbols are used throughout the instruction manual to alert the user to potential
safety hazards as follows :
Warning …Notice when incorrect handling could cause the user's death or serious
injury.
Caution …Notice when incorrect handling could cause injury to the user or material
damage.
Even if the instructions do not have Caution mark, there are some possibilities for
a
Warning and caution symbols
1. Use with the voltage described in the specifications of this instruction manual.
Otherwise, this could cause a fire or malfunction.
2. Use only under combination of these station and iron.
3. Always connect to grounded line. Otherwise, this could cause not only incomplete
electrostatic discharging measures but also irregular temperature control to the tip.
4. Do not handle energized components. This could cause a shock since the grip of
the iron is made of conductive material.
5. Do not modify this product.
6. The tip becomes extremely hot. Never make the following things come closer to the
hot area.
・Human bodies such as hand, face and so on.
・Highly volatile chemicals, such as alcohol and paint.
 Warning
1. Place the station and iron stand on a level and stable surface without vibration.
2. Store in dry surroundings after use.
3. Do not stretch or tightly fold the internal cord or the power cord so as to avoid
damaging these cords. This could cause a short circuit and a fire.
4. Scrub the oxides of the solder, flux on the tip with the sponge of the iron stand. If you
remove the solder by swinging the iron around or by striking it on the edge of a desk
or something, the heater breaks and your body get injured.
Always water the sponge of the iron stand during use.
 Caution

３
１ Put the tip cleaners, the wrapping of which
must be removed, into the pit of the iron
stand.
Sponge
２
Engage the waned
parts of the circles.
The station must be revised according to the tip to be used. See page 5.
Use the exclusive iron stand provided. Other than this could melt the iron.

 Caution
Attach a tip to the iron.
Put the iron on the
iron stand.
Water the sponge.

Power switch
５ Prior to using a new tip, perform tinning
(applying solder to the tip). Put solder to the
tip and wait until solder melts.
Tinning is finished by that the surface is well
covered.
Preparation
If solder balls up and does not stick to the tip, this is too hot or an oxidation film has
soiled the surface. Clean the tip, allow to cool, and begin again.
The tip surface is apt to be oxidized if the iron is heated without load. Set less than
300℃. Previously put solder against the area to be soldered and wait until melts.

 Caution
４ Be sure that the power switch is turned off, then
connect the power plug to the wall outlet.
３ Connect the plug of the iron to the receptacle of the
station.
The contact pins are fixed as the illustration. Engage
the projection at the zenith with the zenith of the
receptacle.
Always ground when use. This is important to prevent operator’s electric shock and to
protect the temperature control circuit from outer noises.
 Caution

２ When finishing work, return the iron back to the iron stand.
Store in a safety place after turning the power switch off and pull the power plug
from the outlet.
５
Operation
Temperature can not be properly managed if the tip surface is
covered with carbide or oxide film. Periodical inspection and
cleaning are recommended. Polish with such as the K-142
Polishing pad. Do not use a coarse file or coarse paper.
Periodical inspection for the tip
Changing the set of using temperature
[Example] Changing the using temperature from 250 ℃ to 340℃.
Press the ▲key to display 340.
When hold pressing, the display changes
quickly. If pass the aim number, collect by
clicks of the ▲key and the ▼key.
Press the SET key. Displayed
Press the SET key. Setting is completed.
If nothing is pressed for 30 seconds, the temperature automatically
returns to the temperature setting before it was changed. The tip
temperature will remain unchanged.
Setting the temperature over 50℃higher than the sleep temperature, which is
explained on page 6, is necessary.
●
１ Turn the power switch on.
The temperature display will rise to 250 in an
instant.
The station is set in 250℃when shipping. Can be
set from 50℃to 450℃, but does not drop under
the surrounding temperature.
The tip has a precise temperature sensor which reacts to methodically soldering load
and keeps temperature near the setting in close cooperation with the station. Therefore,
never set to unnecessary high temperature foreseeing temperature dropping. Please
set to temperature minimum to melt solder. This avoids damaging electro components.
 Caution

Setting the sleep temperature
[Example] Changing the sleep temperature
from 200℃to 150℃. Displayed
Press and hold the SET key until
the display turns to “tPn” after
temperature blinks.
Press the SET key to display “SSt”.
Press the ▲key until the display
changes to 150.
Press and hold the SET key until the set using temperature is displayed.
Setting is completed. The tip will keeps 150℃when the unit becomes in sleep
function.
６
Sleep function
The sleep start timer function automatically
lowers the temperature of the tip after a preset
period of inactivity. This function reduces power
consumption and helps extending soldering tip
life. This sleep function can be used with the
auto power off function (see page 8) together.

Setting the sleep start time
Press and hold the SET key until the set using temperature is displayed.
Setting is completed. The unit will sleep if there is no work over 10 minutes.
Press the ▲key until the display
changes from 5 to 10.
Press and hold the SET key until
the display turns to “tPn” after
temperature blinks.
Displayed
Press the SET key to display “ct”.
While setting the sleep function, the SLEEP lamp
will blink.
The blinking of the SLEEP lamp will
increase 30 seconds before entering sleep mode.
When the soldering station has entered sleep mode,
the SLEEP lamp will change from blinking to contin-
uously lit, and the display will alternate between
“SLP” and the temperature.
●
●
Sleep temperature must be set over 50℃lower than using temperature setting.
●
[Example] Changing the sleep start time from 5 minutes to 10 minutes.
The dot under and right of the temperature display will illuminate when the tip tem-
perature is in the sleep sensitivity and turn off when out of the sleep sensitivity.

Sleep function
Setting the sleep sensitivity
Press and hold the SET key until the set using temperature is displayed.
Setting is completed. The unit will be in the sleep mode if the condition that
the tip temperature does not rise or drop over 5℃continues over the set
sleep start time.
Sleep sensitivity value can be set anywhere between 0℃and 100℃.
If it is set too high, there is a possibility that the sleep function will be activated
even during soldering. If this happens, reduce the sleep sensitivity value.
●
Press the SET key to display “dIF”.
Press the ▼key until the display
changes to 3.0.
[Example] Changing the sleep sensitivity from 5℃to 3℃
Press and hold the SET key until
the display turns to “tPn” after
temperature blinks.
Displayed
The set sleep sensitivity, as the standard for considering that there is no work, is
changeable. The unit is set to 5℃when sipping, and will be in the sleep mode if the
condition that the tip temperature does not rise or drop over 5℃continues over the set
sleep start time.
Canceling the sleep function
If set the sleep start time to 0.00, the sleep function will be turned off and the sleep lamp
will go out.
Returning from the sleep function
To return from the sleep function, do one of the procedures below.
1. Press any key on the control panel.
2. Let the tip contact to the watered sponge.
If setting the sleep temperature to less than 100℃, only the procedure 1. is effective.
To use sleep function manually during the operation, press and hold the ▼key
for one second continuously. This function is very useful for such as leaving the
work booth temporarily.
●
Only for the first time after power on, the longer value of twice of the set time or
10 minutes is applied.

please calibrate the unit as follows.
How to calibrate the temperature
Press the SET key to display “cAL”.
[Example] When the set temperature is 300℃, thermometer value is 295℃, and the
calibration value to be input is 5.
This calibration should be carried out while being revised according to tip type
explained on page 5.

HOZAN’s ESD-safe products are controlled with reference to the Japanese standard (RCJS-5
-1*) which is based on the international standard (IEC61340-5-1).
Products which bear the “ “ mark are products to which the standard values (see table
below) apply. The “ESD Standard” listed on each of the product pages denote the HOZAN
standard for the product.

There is no prescribed “minimum resistance” value for protecting an ESDS device.
However, such a minimum resistance is required in some cases to ensure safety.
