Setting up & Operating the HAKKO 936

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.

A. Iron Holder

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.

* The large sponge may be used alone

(w/o small sponge & water).

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

Note:The iron receptacles for the 900(S) and
the 907/908 soldering irons are different.
Be sure to use the proper one for each
type of soldering iron.
(Refer to Parts List).

3

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

B. Connections

1. Connect the cord assembly to
the receptacle.

2. Place the soldering iron in the
iron holder.

3. Plug the power cord into the
power supply. Be sure to ground
the unit.

C. Set the Temperature

1. Set the temperature control knob
to the desired temperature.

2. Lock the knob.
The HAKKO 936 station is
equipped with a temperature
control knob lock. After setting
the desired temperature,
tighten the hex nut on the
underside of the knob mount
using the supplied hex wrench.
Turn the nut clockwise to tighten
the knob lock.

Receptacle

Turn clockwise firmly

Align the grooves and pins,
and push straight in.

CAUTION : •Don't overtighten the knob lock.

•Don't attempt to turn the knob when the knob lock is on.

D. Turn on the Power
Switch.

The heater lamp blinks on and off
when the tip temperature reaches
the set temperature. The unit is now
ready to perform soldering work.

For greater convenience, and
soldering efficiency, two stations can
be securely stacked as shown.

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

Maintenance

Inspect and Clean the Tip

CAUTION : Never file the Tip to

remove oxide.

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.

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.

Calibrating the Iron Temperature

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

5

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. Remove the CAL potentiometer plug.

4) When the temperature stabilizes, use a straight-edge
(-) screwdriver or small plus (+) 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.
Replace the CAL pot plug.

* 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. (See “Calibrating the Iron Temperature” on page 5.)
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.

Troubleshooting Guide

WARNING : * Disconnect the power plug before servicing.

Failure to do so may result in electric shock.
* If the power cord is damaged, it must be replaced by the manufacturer,
its service agent or similarity qualified person in order to avoid personal
injury or damage to the unit.

Problem 1.

The heater lamp does not
light up.

Problem 2.

The heater lamp lights up
but the tip does not heat up.

Problem 3.

The tip heats up intermittently.

Problem 4.

The tip is not wet.

Check 1. Is the power cord and/or connecting plug
disconnected ?

• Connect it.

Check 2. Is the fuse blown?

• Determine why the fuse blew and eliminate the cause, then
replace the fuse.
a. Is the inside of the iron short-circuited?
b. Is the grounding spring touching the heating element?
c. Is the heating element lead twisted and short-circuited?

Check 3. Is the soldering iron cord broken ?

• Refer to ‘Checking for breakage in the cord assembly.’

Check 4. Is the Heating Element broken?

• Refer to ‘Checking for breakage in the heating element.’

Check 3

Check 5. Is the tip temperature too high?

• Set an appropriate temperature.

Check 6. Is the tip clean?

• Refer to ‘Tip Care and Use’

Problem 5.

The tip temperature is too
low.

Problem 6.

The tip can not be pulled off.

Problem 7.

The tip doesn't hold the
desired temperature.

7

Check 7. Is the tip coated with oxide?

• Refer to ‘Inspect and clean the tip’

Check 8. Is the iron calibrated correctly?

• Recalibrate.

Check 9. Is the tip seized?

Is the tip swollen because of deterioration?

• Replace the tip and the heating element.

Check 8

Checking for breakage of the heating element and cord assembly

Disconnect the plug and measure
the resistance value between the
connecting plug pins as follows.

If the values of 'a' and 'b' are outside
the above value, replace the heating
element (sensor) and/or cord
assembly. Refer to Procedures
1 and 2.

If the value of 'c' is over the above
value, remove the oxidization film by
lightly rubbing with sand-paper or
steel wool the points shown below.

Heating Element (Red)

1. Turn the nut (1) counterclockwise and remove the tip
enclosure (2), the tip (3).

2. Turn the nipple (4) counterclockwise and remove it from the
iron.

3. Pull both the heating element (6) and the cord assembly (11)
out of the handle (12). (Toward the tip of the iron.)

4. Pull the grounding spring (5) out of the D-sleeve.

Senser (Blue)

Measure when the heating element is at room temperature.

1. Resistance value of heating element (RED) 2.5 - 3.5

2. Resistance value of sensor (BLUE) 43 - 58
If the resistance value is not normal, replace the heating
element.
(Refer to the instructions included with the replacement part.)

After replacing the Heating Element,

1. Measure the resistance value between 1) pins 4 & 1 or 2

2) pins 5 & 1 or 2. If it is not , the heating element and
sensor are touching. This will damage the P.W.B.

2. Measure the resistance value 'a','b',and 'c' to confirm that
the leads are not twisted and that the grounding spring is
properly connected.
