1.OVERVIEW

1.4 TO USE THE LASER OSCILLATOR SAFETY

In this manual, the words Warning and Caution, corresponding to different levels of safety requirements, are provided to ensure the user's safety and protect against damage to the laser oscillator.

Moreover, sections entitled Note are used to provide supplementary information.

Before attempting to use the laser oscillator, read Section 2.1 to 2.11, and also the descriptions in the Warnings, Cautions, and Notes that appear in the text.

WARNING

Precautions to be applied in those situations where there is a danger of the operator being killed or seriously injured.

CAUTION

Precautions to be applied in those situations where there is a danger of the operator being slightly injured or the oscillator being damaged.

NOTE

Supplementary information other than precautions.

Before starting any maintenance work, take time to become familiar with the functions of the individual units constituting the laser oscillator, the relationships between the units, and the locations where the units are installed.

WARNING

Never attempt handling, adjustment, or replacement work using a method or procedure other than those described and specified in this manual. Otherwise, dangerous laser light may be emitted.

The function of the laser machining system depends not only on the laser oscillator but also on other system components such as the machine, power magnetics cabinet, servo system, CNC, and operator's panel. This manual covers the laser oscillator only. For information about equipment other than the laser oscillator, refer to the appropriate manuals provided by the machine tool builder.

Take time to become familiar with the contents of this manual.

Store this manual in a safe place.

2 SAFETY

C1000-E, C2000-E, and C4000-E produce the rated output laser power of 1000W, 2000W, and 4000W. The CO2 laser beam is the wavelength of 10.6 m, far infrared, and is invisible to human eyes.

The adequate care must be taken when CO2 laser is operated, therefore. When removing the panel, always turn the power source off and confirm no power is applied to the laser machine.

This oscillator fulfills the requirements of the relevant product safety standard of EN60825-1:1994.

B-70315EN/01

2.SAFETY

2.1 LASER BEAM

1)Potential hazards

Laser oscillator emits CO2 laser beam(10.6 m), which is high power and invisible.

•Being directly exposed to the CO2 beam could severely burn you.

•The CO2 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 CO2 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 CO2 laser beam to protect the personnel from the scattered beam.

Avoid exposure of any part of your body to the CO2 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 CO2 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 materialprocessing machine as a whole, which are to be read.

2.2 HIGH VOLTAGE

1)Potential hazards

There is RF voltage of 3 to 4kVo-p in the cabinet of the laser oscillator.

There is 200 VAC power in the relay panel, be careful not to touch the high voltage.

2)Safety recommendations

When it checks the oscillator and exchange the unit, intercept a main breaker of the oscillator and the power supply. Lock the breaker to prevent misconnection and display the sign while working.

Install safety cover after unit replacement or cable connection. Unless safety cover is installed, never perform operation. Follow standard industrial safety practices for working with high voltage.

EXAMPLES

•Do not work on the laser oscillator if you are tired or have taken medicine.

•Do not wear anything metal, like a ring, bracelet, watch, belt buckle, earrings, or keys.

•They might contact high voltage.

•Never stand on a wet surface.

•Do not touch electrical components in the cabinets with both hands at once. Keep one hand in a pocket.

1)Potential hazards

When you work with the laser oscillator or machine, hot

fragments or slag can scatter from your workpiece. The CO2 beam or a reflection of it could ignite flammable material.

2)Safety recommendations

The direct or scattered laser beam can ignite flammable materials such as paper, cloth, and wood. Provide a beam absorber behind the workpiece and around it during maintenance. The absorber can be anodized aluminum, graphite or brick.Put a shield

between yourself and the workpiece when the CO2 beam is on. Even diffuse reflections can harm eyes and skin and may ignite flammable material.
