Solder

Lead

Nozzle cleaner (Optional parts)

Wipe away any oxide or old solder

from the nozzle using the hole in

the center of the sponge.

2. Clean the tip of the nozzle.

eep the tinned section of the nozzle

clean and shiny 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.

NOTE:

The cleaner is not included.

3. Melt the solder.

• Apply the nozzle to the soldered part and

melt the solder.

NOTE:

Never allow the nozzle to touch the board itself.

• Confirm that the solder is melted.

NOTE:

• 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 if the lead moves, the solder is melted.

• Never move the lead by force.

If it doesn’t move easily, the solder is not yet fully

melted.

4. Extract the solder.

After confirming that the solder is

completely melted, extract the solder by

pushing the button on the iron.

NOTE:

Never leave any solder remaining inside the hole in

the P.W.B.

5. Problems during desoldering.

If solder remains, resolder the component

and repeat the desoldering process.

show the room temperature compensation value (test mode).

3. Room Temperature

Compensation Value.

(Test Mode)

The display will not blink and the heater will not receive power.

The room temperature compensation value is the measured

temperature of the nozzle. This function will be used later to

calibrate the nozzle temperature. (See “Recalibrate the Temper-

ature” on P.13)

No inputs are made here. Press to complete parameter

input. The nozzle temperature setting will be displayed for 2

seconds, after which power will be supplied to the heater and

normal temperature control will begin.

MAINTENANCE

Efficient desoldering depends upon the temperature, the quality and quantity of

the solder and flux. Perform the following service procedures as dictated by the

conditions of the iron usage.

During maintenance, please wear gloves and work carefully.

WARNING:

Since the desoldering iron 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.

Servicing the Desoldering Iron

1. Inspect and clean the nozzle.

• Plug in the power cord, turn the power

switch “ON” and let the nozzle heat up.

• Clean out the hole of the nozzle with the

nozzle cleaning pin.

If the nozzle cleaning pin does not pass

through the nozzle, use the cleaning drill

(option).

NOTE:

• The cleaning drill is not included.

• The cleaning pin will not pass through the nozzle

until the solder inside the nozzle is completely

melted.

• Check the condition of the solder plating,

surface and inside hole of the nozzle.

If it is slightly worn, recoat the tip with

fresh solder.

• If it is worn or eroded, or the inside

diameter seems unusually wide, replace

the nozzle.

NOTE:

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.

• If the cleaning pin and cleaning drill do not

pass through the hole in the nozzle,

replace the nozzle.

The cleaning pin passes

completely through the hole.

Cleaning with the nozzle cleaning pin.

Cleaning with the cleaning drill (option).

• Before cleaning

• After cleaning

Insert the bit while turning it clockwise.

Pull the drill bit out straight without turning it.

solder plating

Diameter of hole is

widened through erosion.

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 diffi-

cult to observe this condition,

therefore, if desoldering effi-

ciency goes down and all

other parts appear to be O ,

the nozzle is probably eroded

and should be replaced.
