1.1 LASER BEAM
Fig.1.1(a)-(j) show the position of panel that laser beam exposure is
occurred without panel.
1) Potential hazards
Laser oscillator emits CO
2
laser beam(10.6 µm), which is high
power and invisible.
• Being directly exposed to the CO
2
beam could severely
burn you.
• The CO
2
beam could bource off your workpiece and burn
your eyes or skin.
LASER oscillator have a guide laser. The guide laser beam
is visible (red color) and low power. It is used to ensure that
the CO
2
beam is correctly positioned on your workpiece.
• The diode laser beam is not considered harmful to your skin.
But if you stared head on into the guide laser 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
2
laser beam to protect the
personnel from the scattered beam.
Avoid exposure of any part of your body to the CO
2
laser beam.
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 laser
oscillator, be sure that the CO
2
laser beam goes from laser to the
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.
