Precautions

CAUTION

· Setting up should be done while the soldering iron is cool, or you may get burnt.

·Do not force the guide pipe bend or turn as this may result in damage.

·Do not operate with tube bending or holding in sharp angle. It may cause to clogging.

·Input of switching is no-voltage input. Do not apply voltage to the jack for switch.

·Periodically, remove the guide pipe and clean out clogged flux.

·Do not force the adjustment screw to adjust the amount of solder return. It may cause to damage.

·If the power cord is damaged, it must be replaced by the manufacturer, its service agent or
similarly qualified person in order to avoid personal injury or damage to the unit.

Setting Up the HAKKO 373

·Setting up should be done while the soldering iron is cool, or you may get burnt.

·Do not force the guide pipe bend or turn as this may result in damage.

·Do not operate with tube bending or holding in sharp angle. It may cause to clogging.

1. Install the Solder Dia.
Adjustment Ring

2. Setting the Guide Pipe
Asse’y

1. Remove the tension gear guide shaft.

2. Attach the solder dia. adjustment ring according to the
diameter of your desired solder and attach the tension
gear guide shaft.

3. Setting the Tube Unit

Setting Up the HAKKO 373

(a)Attach the Tube to Guide

Pipe Asse’y .

(b)Set the Attachment on the

Handle of Soldering Iron.

The tube is double structure. Insert the inside tube into the
hole of the connection, and the outside black tube should
fully cover the screw part of the connection. Be sure that
not to bend the tube.

NOTE

The Att achment is not necessary if you use HAKKO MACH­I.

i. Position the attachment on the handle of iron. Decide

which outlet of attachment should use for the tube as the
tube can be pulled out from either way of the attachment.
Find the best position where can connect the tube straight
to the pipe. Be careful not to damage the inner wiring if
replace the tube inside of the attachment.

ii. Secure the attachment. Set the attachment on the handle

securely with clips and adhesive tape on backside of the
attachment. Refer to the following figure on the setting
position of the attachment and the guide pipe. Pay
attention on the setting angle of the guide pipe and the
attachment.

4. Connect the Feeding
Nozzle

Insert the feeding nozzle into the feeding unit on the top of
the station, and secure it with screw.

NOTE

Securing the screw excessively may break the feeding
nozzle.

5. Connect the Mini-plug Insert the mini-plug branching from the tube unit into the

jack of the station.

NOTE

6. Setting the Solder Set a new solder after pull the old solder out when the old

one left in tube.
(a)Remove the tension gear guide shaft. And attach the

solder dia. adjustment ring according to the diameter of
your desired solder.

(b)Insert the solder bobbin shaft in the solder bobbin and

mount it on rear of the station. Solder should be fed over
the bobbin as the following figure.

(c) Insert the solder from the supply nozzle.
(d)With pressing release lever, put the inserted solder of

approx. 10 mm/0.4 in. into the feeding nozzle through
between tension gears.

.

7. Changing the Solder
Diameter

(e)Power switch on, and set MODE to
(f) Press the trigger switch, and feed the solder.

Replace the solder dia. adjustment ring, when using the
soldering iron continuously but desire to change the
diameter of solder. The guide pipe asse’y should change
according to the diameter of solder. Refer to the section
“Replacement of Parts”.

(a)Power switch off. Open the release lever and roll back

the left solder to the bobbin.

(b)Remove the tension gear guide shaft, and replace the

solder dia. adjustment ring according to desired solder
dia. Remove the tension gear guide shaft turning with a
spanner or pliers.

(c) Replace the guide pipe asse’y if it’s necessary.

8. Use in Vertical Vertical use is available. Fixing in vertical is as following

figure.

Operation

Solder will be fed by pressing the feed switch (or foot switch).

·MODE ·AUTO MODE

If you press the feed switch, solder will be fed with set time
and speed independently of length of pressing time.

·MANUAL MODE

Solder will be fed with set speed during pressing the feed
switch.

·Setting for Feeding
Time and Speed

·Adjustment for the
Amount of Solder
Return

Set the speed before the time. For the setting speed, both

AUTO

for setting time.

After feed solder, specific length of solder can be returned.
This solder return function permits use for simple robots.
Amount of solder return is adjustable within 0~13 mm
(0~0.51 in.). Solder should be rolled back if the amount of
solder return is bigger than the amount of solder feed. Please
set the amount of solder return as small as possible. If the
tip of the returning solder reaches to the guide pipe, flux
will easily accumulate at this point. Be sure that it will not
happen.
Insert a driver into a adjustment hall on the side of the
station. Turn lef t for smaller and turn right for bigger amount.

MANUAL

&

are effective, but only

AUTO

is effective

·Adjustment of Tension When adjust the tension, be sure that not the gear to be

slipped during feed solder, or do not force to feed solder
slipping gear when solder clog.
Set the tension gear loosely for fine solder (ƒÓ0.6mm,

0.8mm/0.024 in., 0.031 in.). Refer to the following chart.

Holder Mounting Base

Set the iron receptacle in the spring iron holder keeping the
iron tip and the guide pipe horizontally.

• HAKKO 631 Simply replace the iron holder if you use with iron holder

HAKKO 631 for except HAKKO 926.

• HAKKO 907, 908 Place the soldering iron in the iron holder so that the right

side of the guide pipe holder fits to the right side of the iron
receptacle.
When you want to fit it to the left side of the iron receptacle,
remove the securing nut for the guide pipe and the
connection; then reattach them in the opposite side.

Troubleshooting Guide

If the solder can not be fed smoothly, please check following points.

·Are you using proper parts according to the diameter of solder?

·Did you adjust the tension properly?

·Isn’t the tube bent or transformed?

·Isn’t solder adhered at the feed gear or the tension gear?

·Isn’t the nozzle clogged with flux?

·Is the mini-plug correctly connected?

·Isn’t the fuse blown?

·Is the power cord correctly connected?
