5
Obligations of
personnel
Before starting work, all persons using the LaserHybrid head undertake:
- to observe the basic instructions regarding safety at work and accident
prevention
- to read these operating instructions, especially the "Safety rules" section
and sign to confirm that they have understood them and will follow them.
Before leaving the workplace, ensure that people or property cannot come to
any harm in your absence.
Personal protective equipment
For your personal safety, take the following precautions:
Persons in the closed cell for the LaserHybrid process must:
wear solid footwear that provides insulation even in wet conditions
protect their hands by wearing suitable gloves (electrically insulated and heatproof)
protect their eyes from laser beams by wearing regulation-compliant laser
safety goggles. In addition, they must protect their faces and eyes from UV
rays using a protective visor and regulation filter element for laser protection
class 4 worn in front of the laser safety goggles and the face. Even when using
this regulation filter element for laser protection class 4, they should not look
into the laser beam.
only wear suitable (i.e. flame-retardant) clothing
Danger from toxic
gases and vapours
use ear protectors to protect them from the cross-jet noise (120 dbA)
If other persons are in the closed cell for the LaserHybrid process, you must:
- make them aware of all the dangers that may occur during operation (e.g.
risk of a build-up of gases that are detrimental to health, possible risk of
suffocation due to lack of oxygen in the air, danger from laser light, etc.)
- provide them with protective equipment
- erect safety screens or curtains
The fumes produced during welding contain harmful gases and vapours.
Welding fumes contain substances that may, under certain circumstances,
cause birth defects or cancer.
Keep your face away from welding fumes and gases.
Fumes and hazardous gases
- must not be breathed in
- must be extracted from the working area using appropriate methods.
Ensure an adequate supply of fresh air.
6
Otherwise, a protective mask with an air supply must be worn.
Close the shielding gas cylinder valve or main gas supply if no welding is taking place.
If there is any doubt about whether the extraction capacity is sufficient, the
measured toxic emission values should be compared with the permissible limit
values.
The following components are responsible, amongst other things, for the degree of toxicity of welding fumes:
- Metals used for the workpiece
- Electrodes
- Coatings
- Cleaners, degreasers, etc.
The relevant material safety data sheets and manufacturer's specifications for
the listed components should therefore be studied carefully.
Flammable vapours (e.g. solvent fumes) should be kept away from the radiation area of the laser and the arc.
EN
Danger from flying sparks
Hazards from
welding current
Flying sparks may cause fires or explosions.
Never weld close to flammable materials.
Flammable materials must be at least 11 m (35 ft.) away from the LaserHybrid
welding process, or alternatively covered with an approved cover.
A suitable, tested fire extinguisher must be available and ready for use.
Sparks and pieces of hot metal may also get into adjacent areas through small
gaps or openings. Take appropriate precautions to prevent any danger of injury or fire.
Welding must not be performed in areas that are subject to fire or explosion or
near sealed tanks, vessels or pipes unless these have been prepared in accordance with the relevant national and international standards.
Do not carry out welding on containers that are being or have been used to
store gases, propellants, mineral oils or similar products. Residues pose an
explosive hazard.
An electric shock can be fatal. Every electric shock is hazardous to life.
All welding cables must be firmly attached, undamaged and properly insulated. Replace any loose connections and scorched cables immediately.
Vagrant welding
currents
If the following instructions are ignored, vagrant welding currents may occur.
These can destroy earthed conductor terminals, the power source being
used, the LaserHybrid welding head and other electrical equipment.
Ensure the workpiece clamp is connected tightly to the workpiece.
On electrically conductive floors, the power source must be set up in such a
way as to be insulated from the floor, wherever possible.
7
EMC measures
Warning, electromagnetic field. Electromagnetic fields may cause as yet
unknown damage to health.
It is the operator's responsibility to ensure that no electromagnetic interference
occurs in electrical and electronic devices.
If electromagnetic interference is found to be occurring, the owner/operator is
obliged to take all necessary measures to prevent this interference.
Check for possible problems, and check and evaluate neighbouring devices'
resistance to interference according to national and international requirements:
- Safety devices
- Power, signal and data transfer lines
- IT and telecommunications devices
- Measuring and calibrating devices
- The health of persons in the vicinity, e.g. users of pacemakers and hearing aids
Individuals with pacemakers must seek advice from their doctor before approaching the welding work area.
Supporting measures for avoidance of EMC problems:
a) Mains supply
- If electromagnetic interference arises despite the correct mains con-
nection, additional measures are necessary (e.g. use of a suitable
line filter)
b) Welding power-leads
- must be kept as short as possible
- must be laid close together (also to avoid EMC problems)
- must be laid apart from other leads
c) Equipotential bonding
d) Earthing of the workpiece
- If necessary, establish an earth connection using suitable capacitors.
e) Shielding, if necessary
- Shield off other nearby devices
- Shield off entire welding installation
Specific hazards
8
Risk of injury to the eyes from the laser beam. In addition to the protective visor
with regulation UV filter element, ensure that all persons wear regulation laser
safety goggles to protect their eyes from laser beams. You should still ensure
that nobody can accidentally look into the laser beam.
With highly shiny, reflective workpiece surfaces, there is a further danger
caused by reflected and scattered laser radiation. Suitable precautions must
be taken to ensure that all persons in the area are sufficiently protected from
scattered laser radiation.
Keep hands, hair, clothing and tools away from moving parts. For example:
- Fans
- Cogs
- Rollers
- Shafts
- Wirespools and welding wires
Do not reach into the rotating cogs of the wire drive or into rotating drive components.
Covers and side panels may only be opened or removed for as long as maintenance or repair work is being carried out.
During operation:
- Ensure that all covers are closed and all side panels are fitted properly.
- Keep all covers and side panels closed.
The welding wire emerging from the welding torch poses a high risk of injury
(piercing of the hand, injuries to the face and eyes, etc.).
Therefore always keep the welding torch away from the body (devices with
wire-feed unit) and wear suitable protective goggles.
Never touch the workpiece during or after welding - risk of burns.
Slag can jump off cooling workpieces. The specified protective equipment
must therefore also be worn when reworking workpieces, and steps must be
taken to ensure that other people are also adequately protected.
Welding torches and other parts with a high operating temperature must be allowed to cool down before handling.
Special provisions apply in areas at risk of fire or explosion
- observe relevant national and international regulations.
EN
Power sources for work in areas with increased electric risk (e.g. near boilers)
must carry the "Safety" sign. However, the power source must not be located
in such areas.
Risk of scalding from escaping coolant. Switch off cooling unit before disconnecting coolant flow or return lines.
Observe the information on the coolant safety data sheet when handling coolant. The coolant safety data sheet may be obtained from your service centre
or downloaded from the manufacturer's website.
Use only suitable load-carrying equipment supplied by the manufacturer when
transporting devices by crane.
- Hook chains or ropes onto all suspension points provided on the load-carrying equipment.
- Chains and ropes must be at the smallest angle possible to the vertical.
- Remove gas cylinder and wirefeeder (MIG/MAG and TIG devices).
If the wirefeeder is attached to a crane holder during welding, always use a
suitable, insulated wirefeeder hoisting attachment (MIG/MAG and TIG devices).
If the device has a carrying strap or handle, this is intended solely for carrying
by hand. The carrying strap is not to be used if transporting with a crane, counterbalanced lift truck or other mechanical hoist.
All lifting accessories (straps, handles, chains, etc.) used in connection with
the device or its components must be tested regularly (e.g. for mechanical
damage, corrosion or changes caused by other environmental factors).
The testing interval and scope of testing must comply with applicable national
standards and directives as a minimum.
Odourless and colourless shielding gas may escape unnoticed if an adapter
is used for the shielding gas connection. Prior to assembly, seal the deviceside thread of the adapter for the shielding gas connection using suitable Teflon tape.

Informal safety
measures
The operating instructions must always be at hand wherever the LaserHybrid
head is being used.
In addition to the operating instructions, any generally applicable and local
regulations regarding accident prevention and environmental protection must
be provided and followed.
All safety and danger notices on the LaserHybrid head must be kept in a legible condition.
Safety measures
at the installation
location
The cell for the LaserHybrid welding process must meet the following requirements:
- be sealed off from adjoining rooms to make it lightproof
- be screened with min. 1 mm thick steel plate and/or approved laser protective glass to prevent any UV or laser radiation escaping
- both the laser welding process and the arc welding process must stop automatically as soon as the cell is opened
A device that topples over can easily kill someone. Place the device on a solid,
level surface.
- The maximum permissible tilt angle is 10°.
Special regulations apply in rooms at risk of fire or explosion
- Observe relevant national and international regulations.
Use internal directives and checks to ensure that the workplace environment
is always clean and clearly laid out.
Only set up and operate the device in accordance with the degree of protection shown on the rating plate.
When setting up the device, ensure there is an all-round clearance of 0.5 m (1
ft. 7.69 in.) to ensure that cooling air can flow in and out freely.
When transporting the device, observe the relevant national and local guidelines and accident prevention regulations. This applies especially to guidelines
regarding the risks arising during transport.
Before transporting the device, allow coolant to drain completely and detach
the following components:
- Wire feed speed
- Wirespool
- Shielding gas cylinder
After transporting the device, the device must be visually inspected for damage before commissioning. Any damage must be repaired by trained service
technicians before commissioning the device.
Safety measures
in normal operation

WARNING! Work that is carried out incorrectly can cause serious injury and dam-
age. Set up work must only be performed by trained and qualified personnel. Observe the safety regulations in the operating instructions, paying particular
attention to the section entitled "Safety inspection".
A low-power pilot laser is required for this set up work.
The position of the focus point for the laser beam relative to the workpiece and the end of
the wire electrode of the arcing process can be adjusted in all three Cartesian coordinate
axes.
The focus point needs to be set in all the coordinate axes:
- after successfully mounting the laser welding head
- each time the laser optics are replaced
- when programming a new reference point
The focus point must be precisely positioned on the surface of the workpiece. To ensure
that this is so, the laser welding head is slowly raised over a test workpiece and simultaneously moved in the feed direction. This continuously rising movement is along a slope that
has previously been programmed in the robot control.
Only the laser is active, not the arcing process.
As the focus point approaches the surface of the workpiece, penetration on the test workpiece increases rapidly.
Due to the height of the laser welding head above the relatively narrow and easily identifiable area of deepest penetration, it is possible to determine the correct setting for the focus
point.
Setting the focus
point - preparations
Switch on the pilot laser
1
Set the height of the laser welding head so that the point of the laser beam on the
2
workpiece is at its smallest diameter.
This height is used as a reference line for the slope that is to be programmed.
Program a slope starting at a laser welding head height of -20 mm and ending at +20
3
mm, measured against the reference line.
To make it as easy as possible to identify the point of deepest penetration, the length
of the slope should be approx. 100 mm.

WARNING! There is a risk of injury when the laser is active. The protection rules
when determining the focus point are the same as those relevant to LaserHybrid
welding (e.g. use a regulation filter element for laser protection class 4 to protect
your eyes, etc.). Observe and follow the safety rules given in these operating instructions.

Safety
Signal sequence
for LaserHybrid
welding
WARNING! Work that is carried out incorrectly can cause serious injury or dam-
age. The welding sequence must only be programmed by trained specialist personnel. Observe the safety rules in the operating instructions, paying particular
attention to the section entitled "Safety inspection".
CAUTION! Risk of damage to optical fibre if laser welding head is positioned perpendicular to the surface of the workpiece during welding.
If the laser optics system is placed at a right angle to the surface of the workpiece,
the laser will be reflected directly into the laser optics system. The optical fibre can
be seriously damaged if this occurs.
Always set the laser welding head at a forwards or backwards tilt angle.
NOTE! When welding a number of short weld seams one after the other, do not
switch off the crossjet flow and external extraction until the end of the entire sequence. This will prevent welding smoke from making the protective glass dirty.
Robot start position:
Set the "extraction on" signal
1
Set the "crossjet on" signal

e.g. mode "3" (internal parameter selection for adjustment purposes):
set mode bit "0" to "1"
set mode bit "1" to "1"
set mode bit "2" to "0"
If "Job" mode is selected, see the operating instructions for the MIG/MAG power
source for more detailed information about this mode.
If preheating is not required, continue from "LaserHybrid welding start position".
Preheating start position:
Requirement: the laser must be ready to enable the beam.
