5.4 LASER
5.4.1 CLASSIFICATION
The classification of lasers is based on the concept of accessible emission limit (AEL), which is
defined for each laser class. The AEL considers not only the emission of the laser produced but
also human access to this emission.
Lasers are grouped into 7 classes: the higher the class, the greater the possibility of causing
damage. The risk to users can be greatly reduced by adopting additional measures of
protection, including supplementary controls, for example, in the form of casings.
The LM-D machine is classified as a class 4 LASER.
HAZARD PROTECTION MEASURES
Class 1 Harmless in normal operation No special measures required
Class 1M Harmless without optical instruments Warn persons using optical instruments
Class 2 Harmless if exposure is momentary Do not look directly at the laser beam
Never direct the laser on the face
Class 2M Without optical instruments: as for class 2
Warn persons using optical instruments
Class 3R Limited hazard Apply the principle of justification. Should be used only by qualified personnel
Class 3B Direct beam always hazardous to eyes
Scattered radiation potentially hazardous
Appoint a safety officer
Cordon off the area of use with architectural barriers
Avoid reflective surfaces
Prevent access by unauthorized persons
Declare the presence of lasers at the entrance
Limit usage only to qualified personnel
Wear protective goggles
Prevent the beam from passing at eye level of standing or seated persons
Class 4 Beam hazardous to eyes and skin
Scattered radiation hazardous to eyes
Fire hazard
The same precautions as for Class 3B
Mandatory use of PPE (personal protective equipment)

avoid direct exposure of the eye and skin to direct, reflected and scattered radiation
take particular precautions to prevent fire risks
use any necessary PPE (see Pt. 5.6).
The Operator must follow all the instructions provided and in particular:
wear the PPE and preserve it carefully, checking its condition before and after each use
never observe the laser beam through fibre optics or focusing systems (telescopes,
microscopes, etc.) without the manufacturer’s authorization, nor observe the beam
directly, even if wearing the safety goggles
take care to avoid uncontrolled and accidental reflections (do not wear watches, etc.)
do not remove or modify the protective devices and interlocking devices and do not
perform any operations which are beyond your competence or could compromise safety
notify the manufacturer of any protective devices that are not working or damaged as well
as of any hazards you may become aware of; in the meantime, the use of the machine
must be suspended and any immediate hazards must be eliminated
ensure that the laser, when not in use, is disabled so as to prevent unauthorized use or
accidental switch-on
ensure that the rooms are cleaned only when the laser is switched off.
Visitors must follow the instructions provided by the Manager and Operator, and in particular:
wear the PPE
never observe the laser beam through fibre optics or focusing systems (telescopes,
microscopes, etc.), nor observe the beam directly even if wearing safety goggles

5.4.3 HAZARDS RELATED TO THE USE OF A LASER DEVICE
Regarding the risks related to using the laser, in Italy the recommendations contained in the
guides CEI 3849R and 3850R must be followed. In other countries, the corresponding guides in
force must be followed.
The Generator is a class 4 laser device with a high optical radiation power. This laser
radiation has a wavelength of 1060-1070 nm and is located in the infrared area. It is
therefore not visible to the human eye.
This characteristic renders it particularly dangerous in that its invisibility does not allow for
any involuntary defensive reactions of the eye which, if hit, will suffer irreparable damage.
The human eye is particularly sensitive to the risks involved in infrared laser radiation
(invisible), as this form of radiation is particularly concentrated by the crystalline lens and
focused on the retina. Extensive irradiation of the retina produces extreme local overheating
and the burning of retinal tissue which means a partial or complete loss of eyesight.
Thus it is recommended that the personnel, during all operations carried out on the open
laser (adjustment, maintenance, repairs), wear laser safety goggles for the appropriate
wavelength.
In the path of the invisible laser beam there may also be introduced the visible pointer
beam (red) with lower power. If observed for a long time, the secondary visible radiation
may cause dazzling.
DANGER TO THE SKIN
The most appropriate laser safety gloves must be selected based on the indications of
standard EN 12477.
There is danger in case of:
direct laser beam
reflected laser radiation
scattered laser radiation.
The skin can take significantly more radiation than the eye. However, it too is subject to the
risk of the destruction of tissue through burning according to exposure time and intensity of
radiation.
Suitable protective clothing should be worn to protect the skin. Safety gloves offer adequate
skin protection, although direct radiation should be avoided.
The minimum recommended level of protection for the laser in question is:
1064 nm - I 5,0 x 105 J/m2
SAFETY EN 01 29/105
OPERATOR’S MANUAL FOR USE AND MAINTENANCE
LM-D
DANGER DUE TO SECONDARY RADIATION: During laser processing, as affirmed, both direct
and secondary radiation occurs, with the secondary radiation occurring in the same
wavelength range as the direct radiation.
DANGER TO THE EYES
The instructions of standards EN 166, EN 207 and EN 208 must be followed in order to choose
the most appropriate laser safety goggles. Utmost attention must be paid to the indelible
marking placed on each pair of goggles.
By way of example: D633L5 + DI700-1100L7 indicates that the goggles guarantee protection
for continuous operation (D) only, at the wavelength of 633 nm with optical density 5, and at
the same time in the wavelength interval of 700 nm - 1100 nm both in continuous and pulsed
mode (DI) with optical density equal to 7.
The filters for laser safety goggles are differentiated as follows:
glass filters that offer high levels of protection and optimal light transmittance
polycarbonate filters which are more lightweight than glass filters, offer good levels of
protection and good light transmittance, and can be used with more ergonomic models of
safety goggles.
The safety goggles required for use with the laser provide protection from direct, reflected
and scattered radiation. Avoid looking directly at the beam even when wearing the safety
goggles. Intense laser radiation can destroy the protective filter.
The minimum recommended level of protection for the laser in question is:
1064 nm - IR LB8
In the case of presumed or certain lesions produced by laser radiation:
Turn off the laser
Immediately inform the senior managers, the persons responsible for protective
measures for the laser, the company doctor and the person assigned to laser safety
Consult a doctor or a specialized clinic.
SAFETY EN 01 30/105
OPERATOR’S MANUAL FOR USE AND MAINTENANCE
LM-D
FIRE HAZARD
The high output power of the laser can burn a large quantity of different materials and
therefore, with open beam path, special fire measures must be taken.
Paper (wiring diagrams, notes or posters hung on the walls), curtains not coated with anti-
inflammatory substances, thin wooden panels and similar materials may all take fire easily on
direct or reflected radiation.
The operations area of the laser beam must not contain containers with solvent substances or
potentially explosive or inflammable detergents even in the course of maintenance.
If there are any solvents or detergents in the area in which the laser is being used, the
respective warnings provided on the containers must be followed.
Should the invisible laser beam at high intensity inadvertently strike one of such containers it
could perforate it and immediately create conditions for a fire to break out or explosion to
take place.
The following extinguishers must be located near the machine and ready for use:
CO2 extinguisher (fire class B) for fires of the dust suction filter or small fires
Powder extinguisher (fire class A, B, C) for the risk of igniting hot waste generated during
the laser processing
A bucket of dry sand (minimum 20 l) or extinguisher (class D) for metal fires.
Combustion due to flames and overheated components:
Keep the fire extinguisher ready
Touch the hot components only with protective gloves on.
Procedure:
Release the shot control
Press the emergency button (if your hands are inside the work chamber)
Switch off the main power switch
Prepare the CO2 extinguishers
Remove the safety system of the CO2 spray extinguisher
Direct the spray onto the flame or into the suction conduit (if present on the system being
used), if the fire has broken out inside the conduit, and discharge the extinguishing spray.

set out in the in the Consolidation Act on Safety at Work, Legislative Decree 81/2008.
The personnel assigned to laser safety must have the required knowledge to evaluate and
check the risks caused by the laser and has the responsibility to supervise the checking of
these risks.
The person assigned to laser safety assumes total responsibility for the safe use of a laser
device and the necessary protective measures required including those involving the safety
and integrity of the personnel assigned to its use.
The training of personnel assigned to laser safety must be guaranteed by an appropriate form
of training by the Manufacturer of the Laser Generator or by Companies with the required
authorization (for example Companies insuring against Accidents in the Workplace).
5.4.5 CONTROLLED AREA
According to standard EN 60825-1, to which the lasers refer, class 4 devices must be used in
well-defined and suitably prepared areas.
The work area must only be accessible to qualified personnel instructed in the use of the laser.
The area must also be enclosed with suitable guards sized according to the parameters of the
laser source.
The access to the class 4 laser zone must be designed so that the opening of the access door or
a mobile guard is detected by a safety system that stops the laser emission before any danger
can be caused to personnel.
The design criteria for this safety system must comply with standard EN ISO 13849-1.
If the presence of an operator is necessary inside the class 4 laser area, personal protective
equipment such as goggles, gloves and other protection should be worn.
The technical features of the PPE must be selected based on the laser parameters and the
operator exposure scenario.
The LM-D Open laser has inputs designed for connection to an interlock on the access door to
the laser area. A further outlet is provided for the installation of an optical warning device near
the access to the area.

6 MACHINE DESCRIPTION
6.1 OPERATING PRINCIPLE
The Class IV Nd-Yag (Neodymium-Yag) laser welding machine provides pulsed light at a
wavelength of 1064 nm and a maximum average power of 60-80-85W (according to the
model).
Designed and built for welding or repair work, it welds cracks and marks with or without filler
material. The repaired piece may undergo further mechanical processes for complete
restoration.
The laser technology permits welding in particularly difficult areas and allows weld seams to be
made with smaller cross sections and very high-quality characteristics.
The laser source is designed to ensure high operational stability both at low and at high power.
The laser pulse transport system allows a smaller beam diameter together with greater laser
spot stability, both in starting transients and with various thermal loads on the laser source.

6.4 LASER SAFETY BARRIERS
The device is equipped with functional laser safety barriers. These provide greater safety to
the operator, ensuring ergonomic use and protection within the maximum optical exposure
limits (EMP) permitted by current regulations. The barriers included are listed below.
NOTE 1: as described above, tampering with or damage to the safety barriers is absolutely
prohibited. The barriers may only be replaced or repaired using material conforming to their
specific technical specifications. It is advisable to contact the manufacturer to obtain original
spare parts.
NOTE 2: The laser radiation from which the screens described offer protection is always
reflected or scattered radiation. These reflections are part of the natural interaction between
the laser and the material being welded. The laser radiation is therefore never direct
(scattered radiation).
NOTE 3: As scattered laser radiation is present, the general provisions described in chapter 5
must be observed. For the required characteristics of appropriate PPE for protecting eyes and
skin, see the technical data in Pt. 5.6.

During the laser processing of particular types of metal materials, carcinogenic substances
may be emitted (e.g.: beryllium compounds, chromium/nickel compounds, zinc chromates):
it is recommended that you verify the existence of this potential hazard depending on the
materials being processed.
The user must make the measurements independently and, if necessary, take appropriate
precautions to protect the personnel.
In particular, it is recommended that you evaluate the composition of the fumes when:
processing metal substances treated with cutting oils, since the harmful fumes may
originate from the liquid lubricants themselves: for example, it is common for
hydrocarbons and aldehydes to be released;
processing plates coated with polyethylene films: in this case mainly aliphatic and olefinic
compounds are released (e.g.: methane, toluene, ethylene).
GAS PROTECTION METHOD
For harmful gases, properly sized molecular absorption filters should be prepared and
installed. Class F5-F9 particulate filters are required, tested in accordance with UNI EN 779, or
alternatively, class E10-H14 absolute filters (HEPA type), tested and classified in accordance

9.7.4 REPLACEMENT AND CLEANING OF THE LASER OPTICS PROTECTIVE GLASS
WARNING: Before replacing or cleaning the protective glass, the laser system must be
switched off and the machine must be isolated from the electric power supply by turning off
the switch on the main switchboard.
This operation is carried out whenever, due to the welding of particularly explosive material,
splatters of molten material are produced which soil or damage the protective glass of the
laser lens.
It also has the function of preventing damage to the focusing lens caused by either accidental
mechanical actions or welding fumes that would damage the surfaces of the objective lenses.
Note that keeping the components of the laser optics perfectly clean guarantees optimal, long-
lasting performance and operation of the system, thereby ensuring high-quality welding.
If the glass is only dirty, proceed with the cleaning, but it must be replaced if damaged.

For the above operations, turn off the generator setting the main switch on the right side of
the machine to OFF.
Open the front door to give easy access to the work area.
Unscrew the ring nut located on the lower side of the objective and visually inspect the
protective glass checking that there are no deep cracks on the surfaces of the glass. When
cleaning the protective glass, use a sheet of special paper for lenses (supplied with the
machine) soaked in solvent (pure acetone).
If the surfaces still contain evident sprays of metal, replace the protective glass otherwise as
the laser beam passes it could cause the glass to break.

9.7.5 REPLACEMENT AND CLEANING OF THE TRANSPARENT SPLASHGUARD GLASS
In order to allow the operator to safely view the interior of the work chamber, the generator
has been equipped with a large protective transparent glass which the laser radiation cannot
pass through, laminated on the internal part of the work chamber to a glass plate designed to
protect the window from splashes, impurities and any accidental mechanical actions which
may occur when positioning the pieces for welding.
The glass plate should be cleaned regularly and replaced when excessively damaged.
The replacement is carried out by removing the upper tabs and lower profile by operating on
the appropriate screws from the interior of the welding chamber.

9.7.6 REPLACING THE AIR FILTER (LM-D, LM-D VISION)
During the welding process, fumes and vapours are released which are suctioned by an
appropriate filtering device inside the work chamber. The filter element is composed of a
spongy filter and metal mesh, and retains the larger impurities. It does not function as an
absolute filter. If welding of items generates poisonous or toxic gases the machine must be
connected to a suitable extraction plant. Replace the filter as follows:
Remove the filter cover mask (with the help of a screwdriver if necessary)
Clean the metal filter and clean or replace the sponge filter.
