3Rules for Safe Operation
1. DO NOT USE IN DANGEROUS ENVIRONMENTS.
Do not use the soldering station in damp or wet locations or expose it to
external environmental conditions, particularly rain. Never use it in an explosive
atmosphere. The heat from the heater can ignite fumes. Be sure that the work area
is well ventilated.
2.
KEEP CHILDREN AND BYSTANDERS AWAY FROM THE SOLDERING STATION.
Do not let bystanders touch the soldering station. All bystanders should be kept a
safe distance from the work area.
3. USE FOR THE RIGHT JOB.
Your soldering station is an electrical tool used to solder parts and melt solder. Do
not use the soldering station for any other purpose. For example: The soldering
station should never be used to warm water or other liquids.
4. WEAR PROPER APPAREL, SAFETY GLASSES, GLOVES AND MASK.
Do not wear loose clothing (such as a necktie). Tie up long hair. Clothing or hair
can burn on contact with the tip or surrounding heated parts.
5. CONNECT TO THE SPECIFIED AC POWER SUPPLY.
The power voltage for this soldering station is indicated at the back of the control
unit. Never plug the soldering station into any other voltage.
6. DO NOT ABUSE THE POWER CORD AND INSPECT IT PERIODICALLY.
Never carry your soldering station by its power cord or yank the power cord to
disconnect it from the receptacle. Keep the power cord away from heat, oil and
sharp edges.
WARNING
The RX-802AS is an anti-static model. Be sure to
properly ground the soldering station using a grounded
receptacle to prevent electric shocks and anti-static. If
it is not properly grounded, electric shocks will occur. As
the soldering station uses conductive materials, please
be careful not to touch any electrical power source or a
serious injury will result.

TAIYO ELECTRIC IND.CO.,LTD.
7. USE STAND PROVIDED.
Be sure to use the ST-21 soldering iron stand included with the soldering station.
If this stand is not used, the plastic parts (adapter ring and/or handpiece) of the
soldering iron unit could be damaged. Position the soldering iron stand on a flat
work-surface or bench.
8. CONCERNING THE TIP.
After turning OFF the power switch, allow the tip to cool naturally. Never use any
other method to cool it down. For example: Water should never be poured or
sprinkled on the tip to cool it down.
9. CONCERNING THE POWER CORD.
IF THE POWER CORD IS DAMAGED THEN THE SOLDERING STATION SHOULD BE
RETURNED TO THE DISTRIBUTOR FOR REPLACEMENT.

NOTE ) If nothing is pressed for 30seconds during setting the temperature, the
temperature on display will be recorded and the display will return to the normal

*The set temperature should be set at 50°C(90˚F) higher than the sleep
temperature (see the section 4-4), otherwise you will not be able to set
the set temperature value. (Example: If the set temperature is set at
200°C(392˚F), the sleep temperature must be 150°C(302˚F) or under.

Example: Changing the temperature from 250°C (482°F) to 340°C (644°F).
When the station is shipped the temperature is set at 250°C (482°F). The temperature
can be set from 50°C (122°F) to 450°C (842°F).
*For the steps given in the operation instructions, only °C is used.

How to set the TIP No.
RX-80HRT-B is mounted in the standard unit. When changing to a different type of
tip, the calibration of the tip temperature is required before starting soldering work.
Otherwise, there may be a difference between the actual tip temperature and the set

How to Calibrate
the Temperature
The RX-802AS can be calibrated using a tip thermometer. Generally speaking, when
measuring the tip temperature of the RX-802AS with a standard tip thermometer, the
measured temperature will usually be lower than that of the actual tip temperature
displayed on the RX-802AS control unit display. This could be because the tip is not
coming into contact properly with the sensor of the tip thermometer. It could also be
because once the tip thermometer comes into contact with the RX-802AS soldering
tip, the metallic parts in the thermometer (for example alumel chromel in the Type-K
thermocouple) conduct heat which transfers away from the RX-802AS tip. This
results in the thermometer indicating a slightly lower temperature than the one in the
RX-802AS display.

The sleep start timer (CT) function automati-
cally lowers the temperature of the tip after a

es power consumption and helps extend sol-

To use Sleep function manually during the operation, press and hold the key for one second
continuously. (Active Sleep function) While setting the Sleep function, the Sleep lamp will flash.
The flashing 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 flashing to
continuously lit, and the display will alternate between “SLP” and the temperature.
When the power is turned ON, no work is started and nothing is pressed on the keypad, the soldering
station will automatically enter Sleep mode either 10 minutes after the power has been turned ON or
in twice the set sleep time (CT), whichever time is longer. However, if soldering is started or keys are
pressed on the control panel, the soldering station will automatically revert to the set sleep start time.
Sleep mode can be exited by rubbing the tip on the moist
sponge. But when Sleep temperature (SST) is 99°C
or below, Sleep mode cannot be exited because the
temperature changing range is too small. To exit Sleep
mode, press any key on the control panel and the tip will
return to the set temperature.

*If the sleep sensitivity value (DIF) 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.
*Sleep sensitivity value (DIF) can be set anywhere between 0°C (0°F) and 20.0°C
(36.0°F).
*If the sleep sensitivity value (DIF) is set to low, there is a possibility that the sleep
function will not be activated even after passing Sleep Start Time (CT) because
the tip temperature can't be stabilized within the range of DIF. If this happens,
