The welding processes produce fumes and gases. Inhaling them can be hazardous to health.
Keep the head away from the fumes. Do not inhale the fumes. Do not cover the vents on the equipment. Carefully read the
instructions supplied concerning the various types of metals, detergents and protection gases. The equipment should ideally be
installed in a large, specially dedicated room. If the room is small, ensure that it is sufficiently ventilated. The protection gases used
for melting can gradually saturate the air causing discomfort or death. Do not weld in the proximity of areas used for degreasing,
cleaning or spraying. The heat could react with the vapours, producing toxic and irritant gases. Make sure that the metals do not
have impurities such to cause fumes or gases during melting. Envision the use of an auxiliary extractor system or, alternatively, the
use of a face mask.
LASER welding can cause fire or explosion.
The sparks produced during welding can escape and cause fire or burns. It is prohibited to introduce inflammable gases and liquids
into the welding chamber. Cylinders and objects containing highly flammable gases or liquids should be moved a safe distance away

Protections
All the safety measures that consist in the use of specific technical means (guards, safety devices) to protect persons from hazards that cannot be
reasonably limited through design are considered as protections.
Tampering with protections or any modification of the equipment can cause risks for the users and for other exposed persons.
Interlock contact
Description
The interlock is a switch with normally closed contact, which must be positioned on the access door/s to the
premiseswhere the equipmentislocated.The electric connectionsofthe switch are shown in the figure below.
Purpose
The interlock contact is used to prevent LASER operation where the safety standards envision the same. This
safety device is mandatory if operating with the welding chamber open or when the welding chamber bottom
is removed. A blind interlock connector is supplied for use of the equipment with welding chamber bottom
inserted and in normal operating conditions.
Operation
When the contact opens, all normal equipment operations are blocked and a warning message is displayed on
the screen, until the contact is restored.
The male DE-9 connector (OME00192) with case (RS000080) is supplied with the equipment; cables and switches are not supplied.
Leather barrier
Description
Several layers of strips of leather form a mobile and permanent barrier at the access aperture to the welding
chamber, through which the operator can introduce his hands and the manufactured productsto be welded.
Purpose
The set-up of this safety device is made necessary in order to preventevery possible leak of radiation from the
welding chamber, prevent the exposure of the operator or persons nearby to the product flashes during the
welding operations and prevent the easy leakage of any protections gases used.
Operation
The leather barrier, which blocks the passage of LASER radiation, can be easily replaced if most of the strips
should be damaged through use, be bent, broken or cut.
Resonator shutter
Description
This device consists of motor-driven flag and is located inside the LASER resonator system. The shutter intervenes
by cutting off the LASER beam path within the resonator when the welder is in stand-
by or in the event of an
anomaly.
Purpose
This device prevents the generation of unwanted LASER radiation.
Operation
The shutter is activated when the power supply is turned on, before the equipment is activated.
On activation, the shutter clears the LASER path, and the equipment 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 equipment is turned off, the shutdown procedure is performed, which closes the shutter; a check is then
performed to ensure correct closure. Any anomalies will always be signalled on the display.
Resonator shutter movements are detected by an infra-red sensor controlled by the movement of the motor shaft.
The breakdown of this infra-red sensor is detected by the microprocessor, which puts the system in the alarm mode,
preventing normal operation of the equipment and highlighting the anomaly with relevant wording on the display.
The breakdown of the motor or its control driver is detected by the microprocessor by checking the ON/OFF
movement implementation times of the flag and is highlighted on the display by relevant warnings.

Operation
Since it is opaque at the wavelength of 1.064 nm, it prevents the passage of LASER radiation.
Welding chamber infra-red 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 the BS EN 207 and BS EN 208 Standards classified as OD6 for protection 800-1090 DIR
LB6. It constitutes the inspection window of the welding chamber and can be replaced if broken.
Purpose
This filter protects the operator's eyes from the LASER radiation during normal operation of the equipment and
allows the manufactured products to be inspected in complete safety.
Operation
Since it is opaque at the wavelength of 1.064 nm, it prevents the passage of LASER radiation.
Emergency button
Description
The emergency button is a red mushroom-shaped switch. It is positioned in a point of the equipment that is
easy to access by the user.
Purpose
It stops the equipment immediately and must be used in the event of danger for the operator or equipment.
Operation
It removes the power supply to all electric/electronic parts of the equipment, switching it off immediately.
Enabling key/PIN
Description
It is an enabling switch with key or, alternatively, an electronic PIN.
Purpose
To prevent operation of the equipment by unauthorised personnel.
Operation
Once the key has been turned or the PIN entered,the equipment starts,loading the internal circuits and enabling
LASER emission.
Hazardous areas and residual risks

Use
See the Safety Information chapterbefore usingthe equipment.
Recommendations
Before proceeding with the normal equipment use, we recommend you check that it was correctly installed and in good working conditions. Check
that its parts are not defective, damaged or worn; if necessary carry out all the necessary routine and extraordinary maintenance operations.
Positioning and ergonomics
Microscope eye pieces
Remove the caps that protect the stereo microscope, insert the eyepieces and, once positioned in their seat, tighten the fixing screw. Keep the
caps and eyepiece wrappersfor future use.
One of the eyepieces has a crosshair for sighting. Position it on the right tube of the stereo microscope. The diopter dial may be
adjusted by rotating the dial clockwise or anti-clockwise dependingon the type of correction required.Referto the scale printedon
each eyepiece.
Safety glasses must have an OD 7 optical density and an L9 protection level for pulsed LASERS with a wavelength of 1064 nm, in
compliance with the relevant BS EN 207 standard.
Turning on the equipment
Move the power supply switch located on the rear panel of the equipment to position I. Wait until the display shows the access screen.
Introduce the password (default value 1234). Press the Start button to start-up the laser andaccess the welding parameters. Set the desired
parameters accordingto the metal to be welded. Use the controlpedal to perform welding.
Emergency stop
The emergency button is used to stop the equipment immediately. This safety device has a locking function and therefore must be re-armed
manually. Use this button only in the case of a hazard and not for normal shut down of the equipment.

liquid etc.
•Options: Entry key to the Options Menu,where some generalLASER settings can be modified, the number of shots verified, the
pump controlled and Firmware updated etc...
•S tart: Welding session start key.
Options Menu
1. Lan guage: Menufor selection of the language of the menu.
2. I nfo: This screen shows information regarding the device in use. In particular, it is possible to know the firmware version currently
installed.
3. Counter: From this menu it is possible to check the total number of shots made by the machine. A partial counter is also available,
useful to check every howmany shots equipment maintenance isperformed.
4. T imeout: Selecting Time-out Display: 1 minor 5 m i ns, withtheLaserStand-by status, the Screen Save r activates automatically after 1 or
5 mi ns of i nacti vity. Se lecting Time-out LASER: 10 mins, the Laser goes into Stand-by after 10 minutes of inactivity.
5. P i n : This menu can be used to modify the start PIN. The user default PIN is 0000. By pressing the N e w PIN key, it is possible to modify
the access PIN using the Touch-screen keyboard. First of all, introduction of the Old PIN is requested. Introduce the old Pin and press
OK. If the PIN introduced is correct then introduction of the new PIN will be requested (New1); Introduce the New PIN and press OK.
Confirmation is requested at this point (New 2). Introduce the PIN again and press OK. If the procedure has been performed
correctly, you automatically go back to the PIN management menu.
6. H2O Menu for coolant liquid system operations. By pressing the ON key, the cooling circuit pump is triggered and the pointer indicates
the flow in litres per minute in circulation. If the system operates correctly, after a few seconds, the pointer indicates a flow higher than
4 litresper minute in the green section.If the pointer remainsin the yellow section or even the red section,the level of liquid must be
checked and, if necessary, coolant must be added or it must be replaced completely.

11. I .U .V.A.P.S.: In this section it is possible to enable the sanitising function by switching the UV lamp on. (O P T I ON AL)
Sanitisation
OFF:The machine and the extraction system operate normally and the UVC sanitising light is off.
ON: The UVClights switch on, thus allowing sanitisation of the environment via normal operation of the equipment fan. This function can be
activated both in ”STANDBY” and in ”START” modes.
P U LS ED: Bypressing the button (PULSED), the "PULSED" function is set, which can only be activated when the machine is in ”STAND-BY” . During
this operation, the fan extracts periodically following two work speeds. In this way, even if the LASER is not used, the environment is sanitised
allowing re-circulation of the air.
