WARNING
Warnings, cautions and notes are placed at critical points in this manual to direct the
operator’s attention to significant items. They are defined as follows:
WARNING: Failure to comply with a WARNING may result in serious injury or death.
CAUTION : Failure to comply with a CAUTION may result in injury to the operator, or
damage to the items involved. Two examples are given below.
● Be sure to comply with the following WARNINGS and CAUTIONS for your safety.
CAUTION
This N2 generator uses membrane technology, which generates the nitrogen gas from
externally-supplied compressed air.
● Cautions for handling the product
•
Carefully handle the product, avoiding impact, such as a blow or dropping.
• Avoid rapid heating or cooling.
• Do not disassemble or modify the main body.
• Store the product indoors avoiding high temperature and humidity environments.
● Cautions for using the product
1. Follow the instructions below when using the product. The nitrogen gas can cause
oxygen deprivation.
• Use in a well-ventilated area.
• Regularly check nitrogen gas discharge piping for leaks.
2. Be sure to note the following points when installing the product. Highly-concentrated
nitrogen gas is discharged from the product into the surrounding area.
• Keep away from flame and flammables.
• Ventilate the work area when in use.
3. The product is intended to generate the highly-concentrated nitrogen gas from
compressed air. Never use it for other than the intended application.
2. An example of setting-up
When the HAKKO FX-791 (N2 station) is used as the nitrogen gas flow rate controller, the
entire apparatus can be set up as shown in the figure below.

*Secure the racks on the HAKKO FX-780 using M3 screws.
CAUTION
When using the HAKKO FX-791, place it on the upper rack and the HAKKO soldering station on the lower rack (diagonally shaded area). The HAKKO FX-791 and HAKKO soldering station can also be placed on the right side of the HAKKO FX-780.
If the soldering station is not placed on the lower rack the HAKKO FX-780 can become unstable and topple over. Always place the soldering station on the lower rack when operating.

3. Adjustment of the flow rate
The flow rate of nitrogen gas is adjusted through the flow rate control valve shown in the
schematic diagram.
The determination of the concentration of nitrogen gas generated by the HAKKO FX-780
depends on the pressure of supplied compressed air and the amount of discharged nitrogen gas. See the table below for detailed information.
Concentration of N2
Amount of discharged N2 re-
mains constant.
Pressure of supplied com-
pressed air remains constant
Pressure of supplied compressed air is high.
Pressure of supplied compressed air is low.
Discharged nitrogen gas is small in amount.
Discharged nitrogen gas is large in amount.
High
Low
High
Low
Determine the pressure of supplied compressed air and the amount of discharged nitrogen gas according to the HAKKO FX-780 performance table.
CAUTION
When using the HAKKO FX-791, the pressure of the HAKKO FX-780 will increase
when the valve is closed. Close the compressed air IN valve of the HAKKO FX-780 to
shut down the supply of compressed air if the flow control valve remains closed for a
long period of time during operating.
4. End of the operation
Close the compressed air IN valve of the HAKKO FX-780.
Open the valves on the side where the gas is discharged, including the flow rate control
valve.
CAUTION
When the N2 generator is not used for a prolonged period of time, stop supplying compressed air to the HAKKO FX-780 and open the valves on the side where the gas is
discharged.
● Nitrogen gas is not
discharged.
CHECK : Is each component properly connected?
ACTION : Verify that air is supplied to the HAKKO FX-780
per the schematic diagram.
CHECK : Is the dust or air filter dirty?
ACTION : Clean or replace the dirty filter.
CHECK : Do the regulator and valves function properly?
ACTION : Repair or replace the nonfunctioning valve(s).
CAUTOIN
If nitrogen gas is not discharged even with a properly-compressed air supplied, the supplied air may be contaminated with dust or moisture. In such a case, the internal module of
the HAKKO FX-780 needs to be replaced by the manufacturer. Module replacement is also required if the amount of discharged nitrogen gas is small or completely zero due to
supply of one of the aggressive gases mentioned in “Conditions of supplied compressed
air” above.
