2Introduction
1. 2 soldering irons can be used
Can be prepared with 2 different tip types.
Therefore, you can do different types of
work at the same time.
2. 150W and 72W soldering irons can be used
simultaneously
Port [1] can be used for the 150W or 72W.
Port [2] can be used for 72W only. You can-
not use 150W in both parts.
3. The 2 soldering irons can be set to different
temperatures.
Port [1] and [2] can be set to different tem-
peratures. The set temperature and condi-
tion can be checked easily with the sepa-
rate temperature display.
4. Excellent heat recovery
Achieved by combining a compact-high-
output heater with a high-sensitivity-sensor.
It makes difficult work that requires high
heat capacity, easy.
5. New ergonomic design soldering unit (PAT.)
Provides comfortable handling, flexible sol-
dering unit cord and a shorter distance from
the grip to the tip.
6. Fastest in its class
Reaches 350˚C (662˚F) in approx. 6 sec-
onds. (Equipped RX-80HRT series )
7. Easy to replace tip without using tools (PAT.)
Slide-change tip. No tools or heat resis-
tance pads needed.
8. Wide variety tip
9 tips for the RX-85HRT series and 7 tips
for the RX-85HSRT series are available. A
total of 43 tips with different shapes includ-
ing the tips for the RX-80HRT series are
available.
9.
Thick iron plating for lead-free soldering
All tips have a thick iron plating to slow ero-
sion caused by lead-free soldering.
10. Key Lock function (PAT.)
Tamper-proof keypad lock using a pass-
word. No tools or cards are needed.
11. Sleep function (PAT.)
The control unit automatically lowers the
temperature when inactive for a preset peri-
od of time, preventing overheating. Time
and temperature can be preset when inac-
tive. Can be used with the shut down func-
tion.
12. Sleep function release (PAT.)
Sleep mode can be exited by touching the
wet sponge to cause temperature fluctua-
tion.
13. Calibration function (PAT.)
The calibration function digitally offsets the
difference between the tip temperature and
the tip thermometer temperature.
14. Shutdown function
When the unit is not used for a preset time,
the unit enters shutdown mode automati-
cally, to prevent any unexpected accidents.
2-1 Features of the RX-822AS
The RX-822AS includes 2 soldering units per one control unit for lead-free soldering. The
tip is a long-life compact type with integrated heater.

3Rules for Safe Operation
1. KNOW YOUR SOLDERING STATION.
Do not attempt to operate this soldering station until you have read thoroughly and
understood completely all instructions, safety, rules, etc. contained in this manual.
Failure to comply may result in accidents involving fire or serious personal injury.
2. DO NOT USE IN DANGEROUS ENVIRONMENTS.
Do not use the soldering station in damp or wet locations or expose it to external envi-
ronmental 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 properly lit and
well ventilated.
3. 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.
4. PROPERLY STORE THE SOLDERING STATION WHEN NOT IN USE.
When not in use, the soldering station should be stored in a dry and locked place.
Keep out of the reach of children.
5. USE FOR THE RIGHT JOB.
This 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.
6. 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.
7. CONNECT TO THE SPECIFIED AC POWER SUPPLY.
The power voltage for this soldering station is indicated at the back of the con-
trol unit. Never plug the soldering station into any other voltage.
8. DO NOT ABUSE THE POWER CORD AND INSPECT IT PERIODICALLY.
Never pull the power cord to disconnect it from the receptacle. Keep the power cord
away from heat, oil and sharp edges. If it is damaged, contact the nearest distributor
for a replacement.
WARNING
Do not operate the soldering station until you have read
and understood the whole manual and safety instruc-
tions.

TAIYO ELECTRIC IND.CO.,LTD.
10 TAIYO ELECTRIC IND.CO.,LTD.

WARNING
The RX-822AS is an anti-static model. Be sure to prop-
erly 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.
9. USE STAND PROVIDED.
Be sure to use the soldering iron stand (ST-21) included with the soldering station. If
this stand is not used, the plastic parts (adapter ring and/or soldering unit housing) of
the soldering iron unit could become damaged. Position the soldering iron stand on a
flat work-surface bench. Follow instructions included with the soldering iron stand to
assemble it.
10.CONCERNING THE TIP.
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.
11.The soldering iron is not intended for use by young children or infirm persons
without supervision. Young children should be supervised to ensure that they do
not play with the soldering iron.

Example : Where the set temperature is 300°C (572°F),
tip thermometer value is 295°C (563°F), and
the calibration value to be input is 5°C (9°F).
3Press the [UP] key to

Press down the [SET.]

or
The RX-822AS can be calibrated using a tip thermometer. Generally speaking, when
measuring the tip temperature of the RX-822AS with a standard tip thermometer, the
measured temperature will usually be lower than that of the actual tip temperature
displayed on the RX-822AS 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-822AS soldering
tip, the metallic parts in the thermometer conduct heat which transfers away from the
RX-822AS tip. This results in the thermometer indicating a slightly lower temperature
than the one in the RX-822AS display.

preset period of inactivity. This function lowers
the tip temperature and it will be in standby
