Safeguards
Safeguards include all safety measures that employ the use of specific technical means (guards, safety devices) to protect people from dangers
that can not 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 the majority
of 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.
Operation
The shutter is activated when the power is turned on, before the device is activated.
Upon activation the shutter clears the laser path, and the device is ready for normal operation. A microprocessor
control checks that the shutter is disabled in a timely manner: any anomalies are indicated by a warning on the
display.
When the machine is turned off the shutdown procedure closes the shutter; a check to ensure proper closure is
then performed. Any anomalies will be shown on the display.
The resonator shutter movements are detected by an infrared sensor controlled by the movement of the motor
shaft. Failure of the infrared sensor is detected by the microprocessor, which puts the system on alert, preventing
normal operation of the device and showing the anomaly on the display.
Failure of the motor or its control driver is detected by the microprocessor by checking the ON/OFF movement
times of the flag and showing an appropriate warning message on the display.
