4-3 Calibration Function
The RX-852AS can be calibrated using a tip thermometer. Generally speaking, when
measuring the tip temperature of the RX-852AS with a standard tip thermometer, the
measured temperature will usually be lower than that of the actual tip temperature
displayed on the RX-852AS 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-852AS soldering
tip, the metallic parts in the thermometer conduct heat which transfers away from the
RX-852AS tip. This results in the thermometer indicating a slightly lower temperature
than the one in the RX-852AS display.

To reset the code number, follow the procedure for "Resetting the Code Number"
shown on page 23.
When doing the "Resetting the Code Number" procedure, the alarm sounds until the tip
temperature falls below 250˚C. This is normal.
The initial temperature setting is 250˚C.
In this case, the temperature range for the alarm is at 250˚C plus/minus 50˚C.
During the resetting, the tip temperature is often out of this range.
That is why the alarm sounds for a short time.

5 Maintenance
CAUTION
The soldering unit is designed so the tip can
be replaced without turning OFF the power.
However, the tip is very hot. Do not touch the
tip or serious burns may result.
The removed tip should be placed in the tip
stand and kept there until it cools down.
5-1 How to Change the Tip
1. Slide the lever on the soldering unit in
the direction of the arrow.
See instruction
p. 34.
3. Plug the new tip into the end of the
soldering unit making sure that the
cut part on the rear end of the tip
is aligned with the cut part of the
soldering unit. Push the tip into the
handpiece as far as it will go. The tip
will not heat up until any key on the
control unit keypad is pushed.
2. Hold the part marked A and pull the
tip out in the direction of the arrow.
The electricity to the soldering unit
automatically goes off as soon as the
lever is slid forward to remove the tip.
4. Press any key on the keypad to start
the flow of electricity to the heater.

5-4 Housing Cleaning
When cleaning, do not at any time allow gasoline, petroleum-based products, penetrating
oils, etc. to come into contact with the plastic parts. They contain chemicals that can damage,
weaken, or destroy plastics.

A lead-free soldering iron is more susceptible to oxidation, and it is more difficult to wet the tip
with solder. Flux within the solder adheres to the tip, carbonizes and blackens. This cannot be
stopped. However, if the user follows the instructions for use and maintenance below, the user
will be able to easily wet the tip with solder consistently.
How to Use, Clean, and Maintain a Lead-Free Soldering Iron
How to use, clean, and maintain the soldering iron
Recommended temperature
The lead-free soldering iron should be set at a low temperature. This slows down
carbonization. Lead-free soldering irons have excellent heat recovery. Reducing
the temperature will not affect the work being carried out. However even at lower
temperatures, flux still carbonizes.
Cleaning tips
During and after use, rub the tip over the sponge or in and out of the tip cleaner metal
shavings while hot to remove the blackened oxidized particles from the tip.
Applying solder
Be careful to keep the solder only in contact with the solder-coated area of the tip.
Using the soldering iron stand
After purchase, the first time you plug in the soldering station, or when resting the iron
in the stand during use, leave a coating of solder on the solder-coated area of the tip
and place it into the soldering iron stand. Only a thin layer of solder is necessary. The
tin surface of a lead-free soldering iron oxidizes easily. Coating it with solder reduces
oxidation levels.
Oxidation starts as soon as the tool is plugged in and begins to heat. When operation
is completed, tin the tip with solder before turning the power off. This protects the tip
from oxidation when it starts heating up the next time it is in use.
TAIYO ELECTRIC IND.CO.,LTD.
What to do when the tip is blackened and not ‘wettable’
Using a clean sponge, repeat the process of ’tinning’ and ‘cleaning’ the tip several times. The
tip surface of an iron that has been in use a short time, generally has a higher ‘wettability’
recovery level.
If this does not remove the discoloration, use a fine grit sandpaper (eg., #600 grit) to remove
any black solid particles and try to ‘tin’ it with solder once more.
Washing and replacement of the cleaning sponge
If the cleaning sponge appears black or brown, rinse out the stains in water. If rinsing does not
remove the stains, replace the sponge.

CAUTION
RX-85HRT replacement tips cannot be used with the RX-802 AS. To prevent improper
usage of these tips, a notch has been added to the RX-85HRT tips so that they cannot be
inserted into the RX-802 AS soldering unit. Attempting to use the R X-85HRT series tips
in the RX-802AS will result in damaging the RX-802AS, because the electric current will
exceed the capacity of the RX-802 AS.
