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.

2. Setting the Guide Pipe

Asse’y

Set the guide pipe asse’y between the nipple (or nut) and

handle, and secure it. Washer may need depend on the type

of iron. Please refer to the following figure.

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.

3. Setting the Tube Unit

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.

(a) Attach the Tube to Guide Pipe

Asse’y.

(b) Set the Attachment on the

Handle of Soldering Iron.

NOTE

The Attachment is not necessary if you use HAKKO

MACH-.

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

Connect the mini-plug of foot switch to the station if you

use HAKKO MACH-.

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.

(d) With pressing release lever, put the inserted solder of

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

between tension gears.

(e) Power switch on, and set MODE to MANUAL .

(f) Press the trigger switch, and feed the solder.

7. Changing the Solder

Diameter

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.

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

46mm 2- 4.2

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

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

AUTO

& MANUAL are effective, but only

AUTO

is effective

for setting time.

Adjustment for the

Amount of Solder

Return

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 left for smaller and turn right for bigger amount.

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 ( 0.6mm, 0.8mm/

0.024 in., 0.031 in.). Refer to the following chart.

Usage of Iron Holder

If you use HAKKO 926, refer to the following figure to set the

iron holder. (As for the HAKKO 926, the setting is available

only on it’s left.)

• HAKKO 926

• 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.
