1. OVERVIEW
OVERVIEW
In this manual, we have tried as for as possible to address all issues.
However, space restrictions prevent us from describing everything that
must not be done, or which cannot be done, because there are so many
possibilities.
Therefore, all matters which are not specifically described as being
possible should be regarded as being “impossible”.

and invisible.
D Being directly exposed to the CO

2
or skin.
FANUC LASER C series have a diode laser. The diode laser beam
is visible (red color) and low power . It is used to ensure that the CO
beam is correctly positioned on your workpiece.
D The diode laser beam is not considered harmful to your skin. But
if you stared head on into the laser diode beam, it could harm your
eyes.
2) Safety recommendations
Never expose the eyes and skin to the laser beam. Be careful of the
laser beam when performing the inspection and maintenance.
Do not turn on the power supply to the oscillator when the panel open
and do not drive. It is bleached to radiation of the laser beam and high
voltage.
Do the countermeasure (For instance, installs safety glasses and the
protection gloves) to danger in case of stopped no finish and nor
opening the panel while it energizes the oscillator.
Install beam safety cover after mirror cleaning or replacement. And if
not beam safety cover installation, do not operation and alignment.
Confirm when it does alignment, the protection pipe (Safety cover) is
installed. If it dose not install the protection pipe, it will put the finger
in the laser beam and there is possibility to do the burn.
When entering the area exposed to the scattered beam, wear the safety
glasses. Mount the stand made of acrylic resin or any material which
can absorb the CO
laser beam to protect the personnel from the
2
scattered beam.
Avoid exposure of any part of your body to the CO
laser beam.
2
When testing the beam output, any personnel other than the
maintenance personnel should be out of the working environment.
In designing a material processing machine utilizing F ANUC LASER
C series, be sure that the CO
laser beam goes from laser to the
2
workpiece only through the enclosed beam delivery system. This
prevents the exposure to laser beam by the operator switch could
otherwise take place. It is absolutely necessary to include the
instructions given here in the manuals of the laser material–processing
machine as a whole, which are to be read.

KEY CONTROL
2.9
SHUTTER LOCK
All the laser products have to comply with the various kinds of laser safety
regulations, which include the use of key control. For instance, FDA
PART 1040 PERFORMANCE STANDARDS FOR
LIGHT–EMITTING PRODUCTS, Sec 1040. 10 (f), (4) states: “Each
laser system classified as a Class IIIb or IV laser product shall incorporate
a key–actuated master control. The key shall be removable and the laser
shall not be operable when the key is removed” and EN60825–1:1994, 4.5
Key control state “Any laser system belonging to one of the following
classes shall incorporate a key operation master control: Class 4 and Class
3B, except for Class 3B with not more than five times the AEL of Class
2 in the wavelength range from 400 nm to 700 nm. The key shall be
removable and the laser radiation shall not be accessible when the key is
removed.”
Because the laser package products offered by FANUC cannot produce
the laser beam as they are in the state of shipment, the system integrator
who incorporates FANUC products into the system, which generates the
laser beam, is obliged to incorporate the master key as defined by the
relevant regulation.
The shutter lock is prepared because it dose not put out the laser beam by
mistake. If you do not put out the beam, lock the shutter.
Use the mechanical switch at shutter lock switch, not electrical
component (Relay)or switching circuit (Transistor, FET).
Use the one with the compulsion dissociation mechanism for the switch
used for the shutter lock circuit and the switch for welding prevention.
To designer of laser processing machine
1. Use a mechanical switch for the switch used to lock the
shutter. Do not use an electric switch (For instance,
transistor circuit, etc.). Moreover, use the one with the
contact dissociation mechanism to prevent welding for a
mechanical switch.
2. Put it in the series of the contact of the emergency stop
button in the shutter lock circuit. When the emergency stop
switch is pushed, it is necessary to intercept the power
supply to the shutter.

FANUC LASER C series are equipped with the warning light optionally.
The light is flashed during discharging and ready of laser beam emission.
Be careful of laser beam and high voltage.
To designer of laser processing machine
In EN60825–1, it needs the design with the fail safe or
redundant for warning equipment. The redundant warning
light is needed near the work–point of processing machine.
The warning light is prepared for the oscillator. Select this as

INAPPOSITE USE OF LASER OSCILLA T OR
Inapposite use and the result are described in each explanation place.
Inapposite major use are described in the following.
(1)The gas with different composition and purity from the specification
is connected with the oscillator.
The oscillator does not work normally and do the protection
movement. In the worst case, the oscillator breaks down.
(2)The gas piping with different material and structure from the
specification is used.
A leakage of the laser gas and a defective composition are occurred.
In the worst case, the oscillator breaks down.
(3)The water piping of the material, which corrodes to water, is used.
Water is blocked by the generation of rust. If cooling water does not
flow in a regulated amount, the oscillator will not work normally.
(4)Cooling water is not regularly exchanged.
W ater is blocked by the generation of rust. Moreover , it is easy for the
water fittings in the oscillator to corrode. In the worst case, the fittings
are damaged and the water leak happens.
(5)The oil of turbo blower and the exhaust pump is not regularly
exchanged.
Turbo blower is damaged and the oscillator does not work. The
exhaust pump is damaged similarly.
(6)The filter of the exhaust pump is not regularly exchanged.
The exhaust ability of the exhaust pump decreases. Moreover, white
smoke comes out from the pump exit and the oil leak happens. In the
worst case, the oscillator does not work.
(7)You will touch an unrelated place when usually maintaining.
In the oscillator there are adjustment place. The adjustment place is the
best value when shipping. When the adjustment shifts, the oscillator
will not work normally. It is necessary to adjust it by service man that
was trained.
(8)You open the panel immediately after the oscillator was stopped and
oil is exchanged.
(9)There is a place of the high temperature immediately after the
oscillator stopped. When you touches there, you will do the burn. After
getting cold of the oscillator, open the panel. Refer to safety in Chapter

Cooling Water Flow Rate
3.6.4
Plumbing
The flow rate should be chosen so that the temperature difference between
the inlet and outlet of the chiller becomes less than 3°C. The customer can
refer to the following table.
Type Flow rate
C1500B 50 liter/min
C2000B, C2000C 75 liter/min
C3000C, C3000D 120 liter/min
C4000A 160 liter/min
C6000B 250 liter/min
The cooling water from chiller is temperature–regulated.
D Choose the tubing material which can withstand corrosion, which will
choke the water flow.
D Make the hose length between the laser and chiller as short as possible.
Along hose makes the pressure 1oss high and becomes a burden to the
chiller pump.
D Place a strainer at the water inlet of laser. It will prevent the f1owing
in of the dust into the laser.
D Place flow meters both at the inlet and outlet of the laser. Daily
checking of the water f1ow contributes to the prevention of abrupt stop
of laser operation.
The water fittings of the inlet and outlet of lasers are shown below.

Laser Gas Tubing
3.7.3
Gas Pipe
Use the gas bottle of the volume of 7m3. Store the necessary number of
bottles according to the operation of the laser.
Drawing of last chapter 1 shown laser gas connection of inlet and outlet.
Inlet and outlet fittings on laser are female PT 3/8”.
(1)Gas inlet of oscillator
D Use the tube designated. (FANUC recommends the use of AS1
tube manufactured by Jyunkosha.)
Do not use a tube possessing high permeability to He. (In the worst
case, the laser will be damaged by improper gas composition.)
D Use the gas of the correct composition.
(2)Gas outlet of oscillator
The oil mist and the dissociated gas come out from the exit of the gas.
Tie the piping of 3/8 inches or more to the gas exit and put it out to
outdoor. It will load the exhaust pump when thin piping or extremely
1ong and the exhaust ability decreases occasionally.
Observe the following cautions for piping between the laser gas cylinder
and laser oscillator.
D Use nylon tube having an inside diameter of 8 mm or larger (Junlon
AS1 manufactured by Junkousha, or equivalent). Do not use a rubber
or urethane tube.
D Use a swage–lock vacuum joint (Fujikin’s product or equivalent). Do
not use a one–touch coupler, quick coupler, or hose–band joint.
D Minimize the length of tubing. It should be kept within 5 m. Never
exceed 15 m. For a length of 15 m or greater, use stainless pipe.
D If it is necessary to use metal pipe for lack of an alternative, use
stainless bright annealed pipe. Minimize the number of joints used.
Connect pipes, if necessary, using a swage–lock vacuum joint or by
TIG welding. Do NOT use silver soldering or copper piping. Piping
should be installed by a vacuum piping specialist. Do not extend metal
piping over 30 m.
D Always keep the piping materials clean. Do not allow foreign matter
to get in the pipe.
D Use a pressure reducer that is free from gas leakage.
D After installing the pipe, check it for gas leakage, using a liquid leak
checker (Gyupoflex: A98L–0001–0856, detecting bubbles caused by
leaking gas) or a clamp test
1)
.
Note
1. Open the valve of the gas cylinder to pressurize the inside
of the pipe, then close the valve. Check to see if the
pressure in the pipe becomes low with time. Monitor the
primary pressure of the gas reducer for over 8 hours. If the
gas pressure becomes lower by 10% within 8 hours, gas is
likely to be leaking. Take an appropriate measure.

Tolerance of Beam Direction
The tolerance of beam direction is "0.3 degrees. The customer is
requested to prepare adjusting mechanism on the machine side to
compensate for the beam direction error.
3.8.4
Beam Guide
The laser had better be isolated mechanically from the machine for
preventing the coupling between them. The vibration might enter the
opponent from each side. It is, however, absolutely necessary to provide
the beam guide between them so that the operator is protected from the
exposure to the laser beam all the time. The structure of the beam guide
must permit the mechanical de–coupling required as shown in the figure.
