7SAFETY
ATTENTION: incorrect implementation of the safety instructions when using the welding machine
described in this manual may expose the user to harmful laser radiation. Follow the procedures
carefully. joke Technology GmbH disclaims all liability for any damage resulting from a failure to
implement the safety instructions provided.
This chapter covers topics relating to personal
safety.The tests carried out on the equipment
demonstrate the safety and reliability of
the laser when used properly. However, the
operator must be aware of the precautionary
instructions designed to avoid the risk of
injuring personnel or damaging the equipment
itself.

8SAFETY
LASER RADIATION
Laser radiations are micrometric wavelength emissions in the far infrared (CO2 laser), near infrared (Nd-YAG
laser, Nd-YVO4), visible (He: Ne or Argon laser), or ultraviolet (excimer laser) regions of the electromagnetic
spectrum.
They are considered non-ionising radiations. In ENESKAlaser 1500 mobile systems, the emission is produced
by a crystal rod when stimulated by the "optical pumping" generated by a laser power lamp. The photons
rebound continuously between a front mirror and a rear mirror, establishing a positive reaction that results in
their number increasing instant by instant; this continues until they reach the concentration necessary to form
a beam, which is projected through the semi-re ective front mirror. The reaction (which we can imagine as an
"invisible light beam") is then collimated and focused using lens to form a point where the intensity is so high
that it can react with different materials, causing an alteration due to the thermal effect.
This means that, while ENESKAlaser 1500 mobile radiation is invisible to the human eye, it is close to the
threshold of visibility, so that the eye receives it almost in its entirety, but without resulting in a pupillary light
re ex. This, coupled with the fact that the beam is generally very intense, means that it can cause very
serious eye damage or even permanent blindness.
To avoid permanent injuries, it is necessary to follow a series of precautions.
Anyone who may be exposed to harmful levels of laser radiation must be aware of when the laser is active
and ensure they are wearing protective glasses.
Due to its high power, the laser installed on the machine causes laser light to be re ected from  at surfaces.
Re ected light is potentially dangerous to the eyes and skin. The micrometric wavelength emission is located
in the far infrared region of the electromagnetic spectrum and is, therefore, invisible to the human eye, this
means that it is not evident where the laser beam is directed.
ABSORPTION OF LASER RADIATION
Human tissue absorbs the electromagnetic radiation differently depending on the wavelength of the radiation
Figure 1 - Eyeball
WARNING: direct exposure to a laser beam can cause irreversible damage to the eyesight.
WARNING: it is essential to protect yourself against beams of re ected light, because they can be
intense enough to cause permanent damage to the eyes or skin.
ATTENTION: This device is equipped with a Class IV laser. Class IV includes all lasers that
can produce risks, not only in the case of the direct or re ected radiation, but also the diffused
radiation. Such laser sources may constitute signi cant risks for the skin, as well as the risk of
igniting in ammable materials.
itself. Both the eye and the skin have their own "predisposition" to absorbing
certain wavelengths, while being more refractory to others. In the case of
the eye, the cornea and the crystalline lens allow all wavelengths between
400 to 1400 nm (corresponding to the region between visible light and
IRA Infrared radiation) to reach the retina, albeit with differing degrees
of attenuation. Therefore, it is immediately apparent that, since Nd: YAG
laser radiation (wavelength 1064 nm) falls within this range, the retina
will be exposed directly to it. With regard to the skin, the "biological
window" differs in terms of absorption percentages but not in terms of
wavelengths. Naturally, the maximum permissible exposure values for
the skin differ considerably compared to the eye.
The damage mechanism caused by absorbed radiation also depends on
the wavelength. Short wavelengths (ultraviolet UV-C 180-280nm, UV-B
180-280nm, UV-A 315-400nm) generally cause photochemical effects:
cataract or opaci cation of the lens in the case of the eye, and melanic colouring or reddening in the case
of the skin. Longer wavelengths (infrared: IR-a 780-1400nm IR-c 3000-10 E6nm) generally cause thermal
effects: detachment and photo-coagulation of the retina in the case of the eye, and burns in the case of the
skin. Naturally, the degree of damage caused depends on the amount of radiation absorbed and on the
instantaneous power of the radiation source.

9
CLASSIFICATION AND HAZARDS
SAFETY
The applicable regulations have established various classes of laser hazard based on their ability to cause
injury in human beings, ranging from class I lasers (intrinsically safe in all conditions) to class IV lasers
(dangerous under a variety of conditions).
Class III includes lasers bearing the "WARNING" label. Such lasers generally do not result in damage to the
eye in the event of momentary exposure (thanks to the eyelid self-defence reex when exposed to intense
visible light), but which may be extremely hazardous if observed through microscopes or magnifying glasses.
Other lasers included in the same class, but bearing the "HAZARD" label may exceed the maximum permitted
exposure level within 0.25 seconds of exposure.
Class IV includes all lasers that can produce risks, not only in the case of the direct or reected radiation,
but also the diffused radiation. Such laser sources may constitute signicant risks for the skin, as well as
the risk of igniting inammable materials. For the reasons listed above, the user must implement all the
measures necessary to conne the radiation so as to ensure that it is terminated at the end of its useful
process. Furthermore, the operator must be aware of the risks deriving from exposure to laser radiation and
be equipped with the appropriate PPE (personal protective equipment) consisting of certied glasses for
protection from laser radiation.
RADIATION VISION CONDITIONS
The laser at the output of the resonator should be regarded as a highly collimated and intense monochromatic
light source. Thus, it may be thought of as a very bright "point source". This means that the resulting "image"
is then focused on the retina in a highly concentrated spot having a dangerously high power density! If, on
the other hand, the beam becomes divergent and spreads out over a non-reecting screen, the image will be
viewed as an "extended" area, having a signicantly less dangerous power density. It is, therefore, possible
to distinguish between different types of radiation vision conditions in relation to the way the radiation itself is
accessed and hence the differing degree of danger.
• Direct vision of the laser beam
This type of exposure is the most dangerous and may occur at the laser aperture, after removing the
optics. This should be avoided at all costs! No protective eyewear can guarantee protection against direct
exposure to the laser beam.
• Direct vision of a specularly reected laser beam
This may occur when the beam is directed at a reecting surface. Viewing a laser beam that has been
reected specularly by a at surface is as dangerous as direct exposure to the beam.
• Direct vision of the beam at the output of an optical bre
This may occur when connecting the optical bre to the resonator. Viewing the beam is dangerous up to
a signicant distance. Filters and safety glasses cannot guarantee safety.
• Direct vision of the beam downstream of the focusing optics
This may occur if the laser beam is not "killed" by a dedicated absorber device at the limit of its working
range. Viewing the beam is dangerous up to a considerable distance. Filters and goggles can guarantee
safety in the event of short exposures, provided they are suitably sized and certied.
• Vision of the diffused laser beam, downstream of the focusing optics
This is the most common vision condition in the case of a device in the working conguration. The beam is
not dangerous unless exposure occurs at a short distance from the optics, but suitable lters and goggles
can guarantee safety, even in the event of lengthy exposure.
The Nominal Ocular Hazard Distance for the ENESKAlaser 1500 mobile is less than 15m in the case
of direct or specular ly reected radiation, and less than 0.5m in the case of diffuse radiation!
Only suitable eyewear having an Optical Density (OD) in excess of 4 is capable of protecting the
eyesight against accidental exposure to harmful laser radiation!

10 SAFETY
RISKS
FOR EYES AND SKIN
If subjected to intense laser radiation, even for brief periods, or to less intense radiation but for extended
periods, both the cornea and the retina may be burnt and damaged irreparably. This is a very real possibility
in the case of exposure to a class IV laser beam.
Direct exposure to focused laser radiation may also cause the skin to burn. Furthermore, it should be noted
that the main radiation may also be accompanied by collateral radiation in the ultraviolet region, which can
cause carcinomas in the event of prolonged exposure.
ATTENTION: Always use certied eye protectors (an example of a certied device is shown
in Fig. 2). Remember that no type of eyewear is capable of protecting against prolonged direct
exposure!
GENERAL SAFETY REQUIREMENTS
In order to avoid compromising the safety level of the equipment, the user must behave appropriately and
ensure that the most rigorous possible safety conditions are maintained at all times. Thus, it is necessary to
develop a Standard Operating Procedure (SOP) relating to the manoeuvres that must be carried out when
activating and deactivating the device. This procedure, displayed near the device, shall serve as a reference
for the Operator and will be written in his own language.
It is also essential to ensure that personnel receive appropriate training designed to:
• Familiarise them with the system operating procedures
• Ensure they are aware of the biological effects of radiation on eyes and skin
• Ensure they understand the need for Personal Protective Equipment (PPE)
An additional risk is represented by the possibility of res if the device is used to process materials other than
those it is intended for. The most serious collateral risk associated with a laser device is, without doubt, the
potentially lethal hazard posed by electricity.
This risk may arise when personnel fail to observe the warnings and procedures imposed by the equipment
manufacturer. Unauthorised and inexperienced personnel must never attempt any kind of intervention on the
electrical part.

11SAFETY
An additional risk is represented by the possibility of res if the device is used to process materials other than
those it is intended for.
COLLATERAL RISKS AND SAFETY SYSTEMS
ATTENTION: If the intended use of the source is altered, for example for material processing
applications, collateral risks may arise due to the production of fumes and vapours that may
be irritating or toxic if they are not extracted and ltered before being reintroduced into the
environment.
NOTE: We strongly recommend that the user does not alter the intended use without having
previously contacted the manufacturer.
CAUTION: When processing ammable materials, since there is a risk of re, it is essential to
follow the instructions provided by the manufacturer when commissioning the machine.
CAUTION: Do not subject materials other than those the device was designed to process to laser
radiation.
NOTE: Do not subject materials other than those the device was designed to process to laser
radiation.
NOTE: When processing ammable materials, such as plastics, since there is a risk of re, it is
essential to follow the instructions provided by the manufacturer when starting the machine.
ATTENTION: Only qualied electrical technicians should work on the electrical parts and
components. Do not remove the protective devices.
WARNING: When processing ammable materials it is essential to follow the instructions provided
by the manufacturer when commissioning the machine.
Safety devices must never be removed and must be checked at regular intervals to ensure that they function
correctly. If, for example, when using the laser source for its intended purpose, the material undergoes
alterations and produces irritating and/or toxic fumes or vapours, it may be necessary to extract and lter the
fumes produced by the process before reintroducing them into the environment.
This LASER welder is equipped with a large number of safety systems to prevent the LASER radiation from
escaping the control of the machine in any way.

SAFETY SYSTEMS
SAFETY
These systems are listed below, together with a description of how they work:
1. Resonator shutter
2. Microscope shutter
3. Microscope infrared lter
4. Infrared welding lter
Description
This device consists of a panel operated by an electro-magnet and
located inside the LASER resonator.The shutter interrupts the path of
the LASER inside the resonator when the welding machine is in
STAND-BY.
Purpose
The purpose of the resonator shutter is to prevent the generation of
unwanted LASER radiation.
Operation
When the electrical power supply is switched on, but before rotating the
key switch to the START position, the shutter is activated. When the
operator rotates the key switch to the START position, the shutter opens
the LASER path, so that the welding machine is ready for normal
operation. When the key is set to the LOCK position, the machine
executes the switch off procedure, the shutter is closed and a check is
performed to ensure that it is closed within the specified time interval.
Description
This device consists of an LCD (liquid crystal display) filter that, when a
specific voltage is applied to it, becomes completely opaque. It is
positioned between the 45° mirror and the microscope focusing lens.
The shutter intervenes by interrupting the operator’s view through the
microscope at the moment the LASER causes the workpiece to melt.
Purpose
The purpose of this device is to:
•Prevent the operator from being dazzled by the flash of visible
radiation light emitted by the weld pool.
As explained later in this manual, the microscope shutter constitutes the
second of three safety devices designed to prevent LASER radiation
from reaching the operator’s eyes indirectly.
Operation
The SHUTTER OPEN position corresponds to the normal operating state
of this device both when the machine is in STAND-BY (resonator shutter
ON), and when it is in START (resonator shutter OFF). This means that
the microscope may be used at any time. After the operator has rotated
the key switch to the START position, the shutter operating logic is as
follows:
•The operator presses the firing pedal;
•The microprocessor detects that the pedal contact has closed
and commands the shutter to close;
•The microprocessor activates the LASER lamp;
•The shutter remains in the ON position for a period corresponding
to the LASER ignition time, plus an additional interval sufficient to
allow the weld pool to cool down and, hence, lose its luminosity.
•The shutter returns to its home position and the system checks
that it is fully open.

4. INFRARED WELDING FILTER

13SAFETY
SAFETY SYSTEMS CONTINUED
Description
Purpose
The purpose of this filter is to protect the operator’s eyes in the unlikely
event of LASER radiation penetrating this section of the microscope
optical path.
Operation
This filter is an optical glass that is opaque to 1.064 nm wavelength
LASER radiation. To the human eye, it appears light grey in colour and
perfectly transparent. It is located inside the microscope (Ref. A,
Figure 3)
Since the glass is opaque to LASER radiation at a wavelength of 1.064
nm, it prevents the LASER radiation generated by the welding machine
from passing, in either direction.
Figure 3 – Microscope infrared lter
Figure 4 – Infrared welding lter
Descrizione
This filter is an optical glass that is opaque to 1.064 nm wavelength
LASER radiation (Ref. B, Figure 4). To the human eye, it appears light
grey in colour and perfectly transparent. It constitutes the welding
chamber inspection window and is designed to be easily replaceable.
