Do not hold onto the heat resistance pad for
a long period.
1. Dial type station
Example: When using an SOP 25L tip at
a temperature of 400 C (750 F), the difference between this tip and CHIP 2L is -5 C
(-9 F).
Set the temperature control knob to 405 C
(759 F).
2. Digital type station
Digital type stations can be calibrated with a room thermometer. Refer
to the compensation value chart
below.
Specific instructions can be found in
your station's instruction manual.
Operating Instructions
1. Set the Temperature
CAUTION
Never set the temperature to any value over
400˚C (752˚F). Doing so may damage the
station.
Set the temperature according to the
type of work to be done.
2. Apply solder or flux.
If there is insufficient solder on the
PWB, or the soldered area is too
small, apply solder or flux to the
PWB. Solder may also be applied to
the tip.
3. Melt the solder
Place the tip on the soldered part and
melt the solder. Confirm that the
solder is fully melted. See sketch `A´.
4.
Remove the componen
After confirming that the solder is fully
melted, lightly squeeze the tweezer to
grasp the component and lift to
remove the component. See sketch
`B´.
t
CAUTION
Very high tip temperatures may damage the
printed circuit board, possibly causing the
printed pattern to become detached. HAKKO
recommends setting the tip temperature to
300˚C (572˚F) for all normal work, and raising it
only when a specific job requires a higher
temperature. Using the lowest possible
effective temperature not only helps protect
parts that are sensitive to heat, it also helps
protect the tip from deterioration caused by
heat.
A
CAUTION
(For users of the HAKKO 937 Soldering Station)
The HAKKO 950 contains a sensor—attached to the heating element in
handle B—to detect the tip temperature. The HAKKO 937 Soldering Station’s heater error function will not
operate if the heating element in handle A is broken.

2. Broken Cord
There are two methods of testing the
cord.
CAUTION
The LED heater lamp will flicker even with a
normal cord if the temperature reaches 400˚C
(752˚F).
3. Checking the tip to
ground resistance
1.
Turn the unit ON and set the temperature to 400˚C(752˚F). Then
wiggle and kink the iron cord at
various locations along its length,
including the strain relief area.
If the LED heater lamp flickers,
then the cord needs to be
replaced.
2.
Check the resistance between the
pin of the plug and the wire on the
terminal in the handle B.
Pin 1: Red
Pin 2: Blue
Pin 3: Green
Pin 4: White
Pin 5: Black
The value should be 0 . If it is
greater than 0 or is , the cord
should be replaced.
If the value of ‘c’ (between pin 3 & tip)
is over the above value 2 as
measured with a tester, remove the
oxidization film by lightly rubbing with
sand-paper or steel wool the points
shown below.

Maintenance
Inspect and Clean the Tip
CAUTION
Never file the Tip to remove oxide.
Tip Care and Use
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 solderplated 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.
•Tip T emperature
•Cleaning
•When Not in Use
•After Use
High operating temperatures can degrade
the tip. Use the lowest possible operating
temperature.
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.
Never leave the HAKKO 950 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.
