Operation (Soldering)

CAUTION : The sponge is compressed. It will swell when moistened with water.
Before using the unit, dampen the sponge with the water and squeeze it dry.
Failure to do so may result in damage to the soldering tip.

1 Assemble the iron

holder for soldering iron.

1. Small Cleaning Sponge
Dampen the small cleaning
sponge with water and then
squeeze it dry. Place it in one
of the 4 openings of the iron
holder base.

2. Add water to approximately the
level as shown.
The small sponge will absorb

water to keep the larger sponge

above it wet at all times.

3. Dampen the large cleaning
sponge and place it on the
iron holder base.

* The large sponge may be used alone
(w/o small sponge & water).

CAUTION : Be sure to turn off the switch before connecting or disconnecting
the soldering iron. Failure to do so may damage the P.W.B.

2 Connections

1. Place the soldering iron in the
iron holder.

2. Connect the cord assembly of
soldering iron

ready to perform soldering work.

CAUTION : The soldering iron must be placed in the iron holder when not in use.

Tip Care and Use

•Tip T emperature

•Cleaning

•When not in use

•After use

High soldering temperatures can degrade the tip.
Use the lowest possible soldering temperature.
The excellent thermal recovery characteristics ensure
efficient and effective soldering even at low temperatures.
This also protects the soldered items from thermal damage.

Clean the tip regularly with a cleaning sponge, as oxides
and carbides from the solder and flux can form impurities
on the tip. These impurities can result in defective joints
or reduce the tip's heat conductivity.
When using the soldering iron continuously, be sure to
loosen the tip and remove all oxides at least once a week.
This helps prevent seizure and reduction of the tip
temperature.

Never leave the soldering iron sitting at high temperature
for long periods of time, as the tip's solder plating will
become covered with oxide, which can greatly reduce the
tip's heat conductivity.

Wipe the tip clean and coat the tip with fresh solder.
This helps prevent tip oxidation.

Operation (Desoldering)

Desoldering

After turning the switch to ON,
wait 3 minutes before beginning
desoldering operations.

1 Set the temperature.

CAUTION

Always set the temperature to as
low as possible for the work being
done.

To more precisely set the
temperature, measure the
temperature at the nozzle
using a soldering iron
thermometer and adjust the
temperature control knob
accordingly.

We recommend the HAKKO
191 thermometer or HAKKO
192 soldering tester for
measuring the nozzle tem­perature.

The temperature can be adjusted between
380˚C (716˚F) and 480˚C (896˚F) with temperature
control knob.
Please refer to the chart below, and adjust
the temperature control knob.

Clean the tip of the nozzle.

2

Keep the solder-plated section
of the nozzle a shiny white by
coating it with a small amount
of solder.

If the tip of the nozzle is
coated with oxide, the
nozzle's heat conductivity
will be lowered.
Coating the tip with a
small amount of fresh
solder ensures maximum
heat conductivity.

9

Wipe away any oxide or old solder
from the nozzle using the hole in
the center of the sponge.

3 Melt the solder.

1. Apply the nozzle to the
soldered part and melt the
solder.

CAUTION

Never allow the nozzle to touch the
board itself.

2. Confirm that the solder is
melted.

CAUTION

To confirm that all the solder is
melted,observe the inside of the
hole and the backside of the P.W.B.
If this is difficult to do, try slowly
moving the lead with the nozzle—oif
the lead moves, the solder is melted.

CAUTION

Never move the lead by force. If it
doesn’ot move easily, the solder isn’ t
yet fully melted.

4 Absorb the solder.

1. After confirming that the
solder is completely melted,
absorb the solder by
squeezing the trigger on
the gun.

Lead

Slowly move
the lead with

CAUTION

Never leave any solder remaining
inside the hole in the P.W.B.

2. After fully absorbing all the
solder, cool the soldering
junction in order to prevent it
from becoming resoldered.

5 Problems during
desoldering

If solder remains, resolder
the component and repeat
the desoldering process.

Absorb the solder by slowly
moving the lead back and
forth with the tip of the
nozzle.

10

Operation (Desoldering)

Heated solder and flux can cause oxides to form and adhere
to the nozzle and the inside of the heating element. These
oxides not only lower the heat conductivity, but can also clog
the nozzle and heating element, resulting in a drop in suction
efficiency. Should there be a noticeable drop in suction efficiency
during operation, replace the filter and clean the nozzle and
heating element with the provided cleaning pin.

Cleaning during Operation

1 Observing the indicator

While looking at the indicator
and with the hole of the nozzle
open, pull the trigger and look
at the indicator. If it is red,
clean the nozzle and heating
element, empty the filter pipe,
and replace the filters. If the
indicator is blue, cleaning is
not necessary and operations
can be resumed.

CAUTION

The indicator will not operate accurate­ly if the hole of the nozzle is closed or
if the solder in the hole of the P.W.B.
is not melted.

2 Replacing the filter

Replace the filter as shown
1 ~ 3 . During operation, the
filter pipe is very hot.
Wait until the filter pipe is cool
before replacing the filter.
We recommend keeping a
second filter pipe containing
new filters handy, and
replacing the installed filter
pipe with this backup filter
pipe.

Normal Abnormal Solution

If the indicator is more
than half red, replace
the filter and clean the
nozzle and the inside

Blue or slight
amount of red
can be seen.

CAUTION :

Replace the entire filter pipe
with the provided backup filter pipe.

More than half
of the indicator
is red.

If there is a noticeable drop in suction
efficiency, clean the nozzle and heating
element with the cleaning pin.

Problems during Desoldering

A. The solder in the junction
is not sufficiently melted.

B. Suction power is dropping.

A. The solder in the junction is not sufficiently melted.

·Temperature is not high enough.

The following parts require a greater heat capacity to
desolder.

• Multilayer P.W.B.s, power supplies, ground planes in
through-hole P.W.B.s, high-capacity transistors, triacs
with heat radiation fins, tuner P.W.B. ground wires,
and large-scale transformer terminals.

Use a preheating oven or heating gun to heat the P.W.B. to
a temperature that won’t damage the board or its compo­nents [between 70˚C (160˚F) and 80˚C (180˚F)], then desol­der. Do not increase the temperature of the gun by recalibra­tion as this may damage the P.W.B. and its components.

·Nozzle is worn out.

• When the nozzle begins to wear out, the heating efficiency
begins to decline. Check the nozzle. If the solder plating
is damaged, or the nozzle is eroded, replace the nozzle.
(refer to p.15)

Post-operation Maintenance

To ensure a long service life, always
perform the following maintenance
procedures immediately after using
the HAKKO 701 unit.

B. Suction power is dropping.

• Replace the filters, and clean the nozzle and the inside
of the heating element. (refer to p.15~20, Maintenance
of the Desoldering Gun and Station )

·Air is leaking from the vacuum system.

Air leakage cannot be determined from the indicator.
Check the air-tightness of the following parts and replace
any that are worn.

a. Contact point of the
nozzle and heating
element
b. Front holder and nearby

c. O-ring in the back holder
d. Hose
e. Vacuum outlet cap
f. Packing and nearby parts

parts

Remove all solder from the inside of the nozzle and
heating element.
Clean the tip of the nozzle with the cleaning sponge,
then coat the tip with a fresh layer of solder to protect
the solder plating.

12

Maintenance (Soldering Iron)

Inspect and Clean the Tip

CAUTION : Never file the tip to

remove oxide.

1. Set the temperature to 250˚C (482˚F).

2. When the temperature stabilizes, clean the tip with the cleaning
sponge and check the condition of the tip.

3. If there is black oxide on the solder-plated portion of the tip, apply
new solder (containing flux) and wipe the tip on the cleaning sponge.
Repeat until the oxide is completely removed. Coat with new solder.

4. If the tip is deformed or heavily eroded, replace it with a new one.76

Calibrating the Iron Temperature

The soldering iron should be
recalibrated after changing the iron,
or replacing the heating element
or tip.

1. Connect the cord assembly plug to the receptacle on the station.

2. Set the temperature control knob to 400˚C (750˚F).

3.

Turn the power switch to ‘ON’ and wait until the temperature stabilizes.

4. When the temperature stabilizes, use a regular or small cross point
screwdriver to adjust the screw (marked CAL at the station) until
the tip thermometer indicates a temperature of 400˚C (750˚F).
Turn the screw clockwise to increase the temperature and
counterclockwise to reduce the temperature.

* We recommend the HAKKO191/192 thermometer for measuring the tip
temperature.

Tips

The tip temperature will vary according to the shape of the tip. The preferred method of adjustment uses a tip
thermometer.
A less accurate method involves adjusting the temperature control knob according to the adjustment value for each tip.
Example : When using a 900M-T-H tip at 400˚C (750˚F),
the difference between this tip and a 900M-T-B is - 20˚C ( - 36˚F).
Set the temperature control knob to 420˚C (786˚F).
Refer to the chart for the correct adjustment values.

the nozzle heat up.

2. Clean out the hole of the
nozzle with the nozzle
cleaning pin.

Since the desoldering gun can reach a very high temperature, please work carefully.
Except when cleaning the nozzle and heating element, always turn the power switch
off and disconnect the power plug before performing any maintenance procedure.

Cleaning with the nozzle cleaning pin.

The cleaning pin passes
completely through the hole.

Cleaning with the cleaning drill.

• Before cleaning

CAUTION

The cleaning pin will not pass
through the nozzle until the solder
inside the nozzle is completely
melted.

If the cleaning pin does not
pass through the hole in the
nozzle, clean with the
cleaning drill.

3. Check the condition of the
solder plating on the tip of the
nozzle.
If it is slightly worn, recoat the
tip with fresh solder to prevent
oxidation.

4. Check the condition of the
surface and inside hole of the
nozzle.
If either is worn or eroded, or
the inside diameter seems
unusually wide, replace the
nozzle.

CAUTION

The inside hole and the surface of
the nozzle is plated with a special
alloy. Should this alloy become
eroded by high-temperature solder,
the nozzle will not be able to maintain
the proper temperature.

15

• After cleaning

Pull the drill bit out straight without turning it.

solder plating

Diameter of hole is
widened through erosion.

Insert the bit while turning it clockwise.

CAUTION

If the cleaning drill is forced
into the nozzle, the drill bit
could break or be damaged.

CAUTION

Please use the proper sized
cleaning pin or cleaning drill
for the nozzle diameter.

Note

Unfortunately, it is often diffi­cult to observe this condition.
Therefore, if desoldering effi­ciency goes down and all oth­er parts appear to be OK, the
nozzle is probably eroded and
should be replaced.

2 Disassemble the heating
element.

CAUTION

The heating element is very hot
during operation.

Replacing the Heating Element

WARNING

Unplug the power cord before
starting this procedure.

The resistance value of a working
heating element is 2-4

at 23˚C
(73˚F). If the value you get is
outside this range, replace the
heating element.

1 Disassemble the heating
parts.

2 Separate the housing.
3 Detach the terminal and

remove the heating
element.

4 Insert a new heating
element and reassemble.

(Heating element 24V-50W)

CAUTION

Before reassembling enclosure,
make sure connectors are completely
covered by the glass tube.

5 Recalibrate the tempera­ ture.

The resistance of new heating
element varies, resulting in
variations in operating tem­ peratures. It is necessary to
recalibrate the temperature
every time the heating element
is replaced.

1. Set the temperature control
knob to 1 and allow the gun
to warm up for 3 minutes.

2. Measure the tip with a tip
thermometer. Using a straight­ edge (-) or small cross point
screwdriver, adjust the tem­ perature calibrator (marked
“CAL”) until the nozzle tem­ perature reads 380˚C(716˚F).
Turn the temperature calibrator
clockwise to increase the
temperature and counter­ clockwise to reduce the tem­ perature.

Remove the filter pipe.

Housing

Unscrew the screws.

Detach
the terminal.

Glass Tube

Cover the glass tube
on the connecting part.

Bend the lead
before inserting it.

Position the leads in groove
and press them into place.
Be careful that the leads do not
get caught in the housing.
