CAUTION:
Misuse may potentially cause injury to the user or physical damage to the objects involved.
For your own safety, be sure to comply with these precautions.
When the power is on, the tip temperature is between 200°C/392°F and 480°C/ 896°F. Since mishandling
may lead to burns or fire, be sure to comply with the following precautions.
Do not touch the metallic parts near the tip.
Do not use the product near flammable items.
Advise other people in the work area that the unit can reach a very high temperature and should be
considered potentially dangerous.
Turn the power off while taking breaks and when finished using the unit.
Before replacing parts or storing the unit, turn the power off and allow the unit to cool to room
temperature.
To prevent damage to the unit and ensure a safe working environment, be sure to comply with the
following precautions.
Do not use the unit for applications other than soldering.
Do not rap the soldering iron otherwise subject the iron to severe shocks.
Do not modify the unit.
Use only genuine replacement parts.
Do not wet the unit or use the unit when your hands are wet.
The soldering process will produce smoke, so make sure the area is well ventilated.
While using the unit, don't do anything which may cause bodily harm or physical damage.

Setting up & operating the Soldering Station
A. Iron Holder
Before using the unit, dampen the sponge with the water and squeeze it dry.
B. Connections
CAUTION: Be sure to turn off the power before connecting or disconnecting the soldering iron. Failure
to do so may damage the P.W.B.
1. Connect the soldering iron cord into the receptacle.
2. Place the soldering iron on the iron holder.
3. Plug the power cord into the power supply. Be sure to ground the unit.
C. Set the Temperature
1. Turn the power on.
2. Set the temperature control knob to the desired temperature.
3. When the tip temperature reaches the setting temperature, the heater indicator of SS-207 will flash then
off, it means the temperature under control now, if it lights up red, means on heating. The heater
indicator of SS-206 will flash then off, it means the temperature under control now, if it lights up red,
means on heating now.
CAUTION: The soldering iron must be placed on the iron holder when not in use.
Tip maintenance and use
Tip temperature
High soldering temperature 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.
Cleaning
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.
When not in use
Never leave the soldering iron sitting at high temperature for long periods of time, at the tip's solder plating
will become covered with oxide, which can greatly reduce the tip's heat conductivity.
After use
Wipe the tip clean and coat the tip with fresh solder. This helps prevent tip to oxidation.
Maintenance
Inspect and clean the tip
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 position of the tip, apply new solder (containing flux) and
Problem1.
The heater lamp does not light
up.
Check 1. If the power cord and/or connecting plug disconnected?
*Connect it.
Check 2. If the fuse blew and eliminate the cause, 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?
Problem 2.
The heater lamp lights up, but
the tip does not heat up.
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.
Problem 3.
The tip heats up intermittently.
Refer to Check 3
Problem 4.
Solder will not wet the tip.
Check 5. Is the tip temperature too high?
*Set an appropriate temperature.
Check 6. Is the tip clean?
*Refer to Tip maintenance and Use.
Problem 5.
The tip temperature is too low.
Check 7. Is the tip coated with oxide?
*Refer to inspect and clean the tip.
Check 8. Is the iron calibrated correctly?
*Recalibrate.
wipe the tip on the cleaning sponge. Repeat until the oxide is completely removed, and coated with new
solder.
4. If the tip is deformed or heavily eroded, replace it with a new one.
CAUTION: Never file the tip to remove oxide.
Calibrating the iron temperature
The soldering iron should be recalibrated after changing the iron, or replacing the heating element or tip.
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 on, wait until the temperature stabilizes, Remove the CAL pot 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.
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.)
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 similarly qualified person in
order to avoid personal injury or damage to the unit.
6
Problem 6.
The tip can not be pulled off.
Check 9. Is the tip seized?
Is the tip swollen because of deterioration?
*Replace the tip and the heating element.
Problem 7.
The tip doesn't hold the desired
temperature.
Check 8
a. Between pins 1 & 5
(Sensor)
≈50Ω
b. Between pins 2 & 4
(Heating Element)
≈4Ω
c. Between pin 3 & Tip
Under 2Ω
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 as shown.
Heating Element Broken
Disassembling the Unit
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.
7
Measure when the heating element is at room temperature.
Heating element lead diagram
1. Resistance value of heating element (resistance between the 2 red lines) ≈4Ω
2. Resistance value of sensor (resistance between the 2 blue line) ≈50Ω
If the resistance value is not normal, replace the heating element.
Replace the Heating Element.
(1) De-solder the damaged heating element leads and remove it.
(2) Replace a new one and solders to PC board properly.
(3) Solders the two lead of heater to the other side of PC board, bend the leads at right triangle when
soldering to prevent short-circuit
After heating element replaced:
1. Measure the resistance value between pins 3 & 4 or pins 3 & 5 or pin 4 & 5. If it is not ∞, the heating
element or sensor touching the housing ground, it must be eliminated; otherwise will damage the PCB
2. Measure the resistance value between all leads' to confirm that the leads are not twisted and that the
grounding spring is properly connected.
Soldering iron cord damaged
Testing the soldering iron cord
8
Check the resistance between the pin of the plug and the wire on the terminal.
Pin 1: Black Pin 2: Red Pin 3: White Pin 4: Black Pin 5: Red Pin
The value should be <2Ω. If it is more than 2Ω or ∞, the soldering iron need to be replaced.
Fuse replacement
When fuse is blown, replace with the same type of fuse. (refer to below picture)
1. Unplug the power cord from the power receptacle.
2. The fuse holder is located under the AC power receptacle, use the slotted (–) screwdriver to loosen
the fuse holder
3. Replace the fuse with new one
4. Put the fuse holder back in place
