1 x User manual
CAUTION
• Attaching the nozzle.
Do not press the nozzle or pull on the edge of the nozzle by pliers. Also, do not retighten the screw too
tightly
• Thermal protector.
For safety, power is automatically shut off should the unit exceed a certain temperature. Once the tem-
perature has dropped to a safe level, power is automatically restored. After that, to continue operation,
reduce the temperature setting or increase the air flow. Should the thermal protector be tripped and you
do not wish to continue the operation, or if you leave that place, be sure to turn the power switch off.
• Caution-High Temperature Operation.
Do not use the SMD unit near ignitable gases, paper, or other inflammable materials.
The hot air is extremely hot and can cause painful burns. Never touch the heater pipe or allow the heated
air to blow against your skin.
• When LED is illuminated, the station is heating.
• Never drop or sharply jolt the unit.
The pipe contains quartz glass which can break if the unit is dropped or jolted sharply.
• Do not disassemble the pump.
• Disconnect the plug when you don’t use the unit for a long time.
When the power cord is connected into the power supply, the unit has a little flow of electricity, even the
Power Switch is in off setting. So then you don’t use the unit for a long time, disconnect the plug.
• When the temperature is over 350°C the airflow control knob should be at 3rd-8th setting.
• When the working temperature is over 450°C, the air flow control knob must be over 4th set-
ting.

WARNING!
Make sure to remove the 4 transit screws on the base before use, otherwise serious damage may
be caused to the machine.
This tool must be placed on its stand when not in use.
A fire may result if the appliance is not used with care, therefore
• Do not use in presence of an explosive atmosphere;
• Be careful when using the appliance in places where there are combustible material;
• Be aware heat may be conducted to combustible materials that are hidden out of sight;
• Do not apply heat to the same place for a long time;
• Place the appliance on its stand after use and allow it to cool down before storage;
• Do not leave the appliance unattended when it is switched on.
This appliance can be used by children aged from 8 years and above and persons with reduced physic-
al, sensory or mental capabilities or lack of experience and knowledge provided they have been given
supervision or instruction concerning use of the appliance in a safe way and understand the hazards
involved. Children shall not play with the appliance. Cleaning and user maintenance shall not be made
by children without supervision.
Operation
Before Operation
1. Select the FP pick-up wire that matches the size of the IC.
2. Select the nozzle that matches the size of the IC.
3. Attach the nozzle on the head part, then start your work.
The display and temperature setting
1. Shows the actual temperature of the tip/nozzle.
2. Shows the setting temperature. Short press the “UP”/“DOWN” button to adjust the temperature by ±1°C.
Long-press the button to adjust it quickly.
3. Press the °C/°F button to change the temperature unit between °C and °F.
4. When the actual temperature of the tip/nozzle is lower than the setting, “HEAT ON” will display.
5. When the difference is more than ±10°C between the actual and setting temperatures, “WAIT” will
display. Wait until it has disappeared.
6. When “ERROR” displays, there may be some problem with the system. Or the soldering iron/hot air gun
is not correctly connected.

QFP Desoldering
• Plug the power cord into the power supply
After connection, the automatic blowing function may start sending air through the pipe, but the heating
element remains cool.
• Turn the Power switch on
The power switch may be turned on at any time while the automatic blowing function, is operating.
Once the power switch is turned on, the heating element will begin to warm up.
• Adjust the air flow and temperature control knobs
After adjusting the air flow and temperature control knob, wait for the temperature to stabilize for a
short period of time. We recommend you to adjust the temperature around 300 to 350°C. As for air
flow in case of single nozzle, set the knob 1-5, in another nozzle, set it from 4-7. When the working
temperature is over 450°C, the knob of airflow control must be over 4th setting.
• Place the FP pick-up under IC lead
Slip the FP Pick-up Wire under the IC lead. If the width of the IC does
not match the size of the FP Pick-up, adjust the width of the
wire by suppressing the wire.
• Melt the solder
Hold the iron so that the nozzle is located directly over, but not
touching the IC, and allow the hot air to melt the solder. Be
careful not to touch the leads of the IC with the nozzle.
• Remove the IC
Once the solder has melted, remove the IC by lifting The FP Pick-up.
• Turn the power switch off
In case you don’t use the unit for a long time, disconnect the plug.
• Remove any remaining solder
After removing the IC, remove remaining solder with a wick or desoldering tool.
Note: in case of SOP, PLCC desolder it by using tweezers, etc.
QFP Soldering
• Apply the solder paste
Apply the proper quantity of solder paste and install the SMD on the PWB.
• Preheat SMD
Refer to the photo to preheat SMD. (Fig. I)
• Soldering
Heat the lead frame evenly. (Fig. II)

• Washing
When soldering is completed, please wash away the flux. Note: While you do soldering by hot air, the
defects such as solder balls, solder bridges might occur. We recommend you to examine the conditions
of soldering sufficiently.
• Automatic cooling system:
When the job is finished, you can adjust the temperature to 160°C, then turn off the air control
switch, the display will be closed. The air pump will blow cool air for about 1 minute to cool down
the machine. Then turn off the main power switch.
