Do not use water to clean the device.
Do not use water near the device when it is in operation. Do not place liquid containers above the device. Do not place the device
in a moist environment (acceptable relative humidity is between 30% to 80%)or near sources which produce heat or moisture.
Protective clothing should be worn.
Wear protective clothing such as gloves, long-sleeved jackets, leather aprons, etc. Sparks and molten metal splashes can cause burns
on the skin.
Do not cover the laser with blankets or fabric materials.
Do not cover the device during operation with blankets or fabric materials, as these may overheat and burn.
Perform regular maintenance.
Refer to the specific chapter in this manual and perform the suggested maintenance. In the event a problem arises, do not use the
device; consult the manual and call for service.
The manufacturer assumes no liability for direct or indirect damages to persons, property or animals resulting from failure to comply
with safety standards and the instructions contained in this manual.
Safeguards
Safeguards include all safety measures that employ the use of specific technical means (guards, safety devices) to protect people from dangers
that cannot be reasonably limited by design.
Tampering with the safeguards or any modification of the device may cause risks to users and other exposed persons.
Interlock
Description
The interlock is a normally closed switch that should be placed on the access door(s) to the room where the
device is located. The interlock switch electrical connections are shown in the figure below.
Purpose
The Interlock switch serves to prevent operation of the laser when safety issues arise. This precaution is
mandatory if working with the welding chamber open or when the bottom of the welding chamber is removed.
A blind interlock connector is provided for use on the device with the bottom of the welding chamber inserted
and under normal operating conditions.
Operation
When the switch is opened normal device functions are disabled and a warning message is displayed on the
screen until the switch is closed again.
The DB9 male connector, cables and switches are provided only upon request.
Leather curtains
Description
Several layers of leather strips form a movable and permanent barrier at the access openings to the welding
chamber through which the operator can insert hands and objects to be welded.
Purpose
This safety device is necessary to prevent any potential radiation escaping from the welding chamber, and to
prevent the operator or people close by from exposure to the flashes produced during welding operations, as
well as to prevent any leakage of shielding gas in use.
Operation
The leather curtain, which blocks the passage of laser radiation, is easily replaceable in the event most the strips
are damaged, bent, broken or cut through usage.
Resonator shutter
Description
This device consits of motor-driven flag located inside the laser resonator system. The shutter cuts off the laser beam
path within the resonator when the welding machine is in stand-by or in the event of an anomaly.
Purpose
The purpose of this device is to prevent the generation of unwanted laser radiation.
