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.
Infrared microscope filter
Description
This filter is a 1.064 nm optical glass that is opaque to laser radiation. It appears clear and transparent grey to
our eyes. It is located inside the microscope.
Purpose
The purpose of this filter is to protect the operator's eyes from laser radiation leaks along the optical path of the
microscope.
Operation
Opaque at a wavelength of 1.064 nm, it prevents the passage of laser radiation.
Infrared welding chamber filter
Description
This filter is a 1.064 nm optical glass that is opaque to laser radiation. It appears transparent light-green to our
eyes in compliance with EN 207 and EN 208 standards and is classified as OD6 for 800-1090 DIR LB6 protection.
It forms the viewing window of the welding chamber and is replaceable in case of breakage.
Purpose
The purpose of this filter is to protect the operator's eyes from laser radiation during normal operation of the
device and permit inspection of objects in complete safety.
Operation
Opaque at a wavelength of 1.064 nm, it prevents the passage of laser radiation.
Emergency button
Description
The emergency button is a red, mushroom-shaped switch positioned on the device for easy access by the user.
Purpose
The button immediately stops the device, and is for use in the event of danger to the operator or the device.
Operation
The button cuts power to all electrical parts/electronic equipment instantly.
Enabling key/PIN
Description
An enabling switch operated by key or, alternatively, by an electronic PIN.
Purpose
It prevents operation of the device by unauthorized personnel.
Operation
Once the key is turned, or the PIN is entered, the device starts charging the internal circuitry and enabling laser
emission.
Danger zones and residual risks
A danger zone is defined as any area within or near the device in which a person is exposed to risk of injury or damage to health. Residual risks
for the operator exist during some device operation procedures. These risks can be eliminated by following basic work and behavior rules or,
more specifically, the procedures in this manual, and by using personal protective equipment if indicated.
This device should be installed solely and exclusively by personnel trained in its handling and who have completely read the safety
instructions in this manual.
General rules
Before beginning regular use of the device, it is recommended checking to ensure that it is in suitable working condition and that
there are no defective or worn parts. Perform any necessary maintenance operations.
•
Pay attention to the danger of electric shock from both direct and indirect contact caused by unexpected failures of the electrical
system.
•
Do not subject the device to severe impacts.
•
Do not expose the device to fire, weld splashes, or extreme temperatures.
•
Do not allow the device to meet corrosive substances.
•
Do not wash the device with water jets.
Before every use of the device
For proper use of the device, keep in mind the following guidelines:
•
Never insert objects into the slots on the device.
•
Always stop the machine by using the red button on the display after each work session, and turn off the main switch only after the
machine has shut down.
•
Perform the maintenance operations indicated in the maintenance section.
•
If the laser output nozzle is dirty, clean it with a dry or slightly damp cloth. If it is very dirty, use a mild detergent such as alcohol. Never
use thinner, gasoline, etc., as these may discolor or otherwise damage plastic parts. If the protective glass is damaged or overly saturated
with metal, replace it with a new one.
