Personal Protec-
tive Equipment
Please take the following precautions for your own personal safety:
Persons present in the sealed cell for the LaserHybrid process must
- wear rigid, wet-insulating footwear
- protect hands with appropriate gloves (featuring electrical insulation and thermal pro-
tection)
- protect their eyes from laser beams by wearing regulation-compliant safety glasses for
lasers. To protect their face and eyes against UV beams, further protection in the form
of a protective shield with regulation-compliant filter insert for laser protection class 4
must also be used in front of the safety glasses for lasers and the person's face. Do
not look into the laser beam, even with a regulation-compliant filter insert for laser pro-
tection class 4.
- Only wear suitable (flame-resistant) clothing
- Wear hearing protection designed for crossjet noise (120 dbA)
If there are persons present in the sealed cell for the LaserHybrid process,
- inform them of all the dangers that may be posed during operation (e.g. potential ac-
cumulation of gases hazardous to health, risk of asphyxiation due to lack of oxygen in
the breathable air, hazards posed by laser light, etc.)
- provide protective equipment
- construct protective walls or install protective curtains.
Danger from Tox-
ic Gases and Va-
pors
The fumes produced during welding contain toxic gases and vapors.
Welding fumes contain substances that may cause birth defects and cancer in some cir-
cumstances.
Keep your head out of the welding fumes and gases.
Take the following precautionary measures for fumes and harmful gases:
- Do not breathe them in.
- Extract them from the work area using appropriate equipment.
Ensure that there is sufficient fresh air.
Use breathing apparatus with air supply if there is insufficient ventilation.
When no welding is taking place, close the valve of the shielding gas cylinder or the main
gas supply.
If there is uncertainty as to whether the extraction capacity is sufficient, compare the mea-
sured toxic emission values against the permissible limit values.
The following components are factors that determine how toxic the welding fumes are:
- The metals used for the workpiece
- Electrodes
- Coatings
- Cleaning agents, degreasers, and the like
Consult the corresponding material safety data sheets and manufacturer's instructions for
the components listed above.
Keep flammable vapors (such as solvent vapors) out of the laser and arc radiation range.
Danger Posed by
Shielding Gas
Leak
Risk of asphyxiation due to uncontrolled shielding gas leak

10
Shielding gas is colorless and odorless and may suppress the oxygen in the ambient air in
the event of leakage.
- Ensure there is a sufficient supply of fresh air with a ventilation flow rate of at least
20 m³ per hour.
- Please observe the safety and maintenance information for the shielding gas cylinder
or the main gas supply.
- When no welding is taking place, close the valve of the shielding gas cylinder or the
main gas supply.
- Always check the shielding gas cylinder or main gas supply for uncontrolled gas leak-
age before each start-up.
Danger from Fly-
ing Sparks
Flying sparks can cause fires and explosions.
Never undertake welding near flammable materials.
Flammable materials must be kept at least 11 meters (35 ft.) from the LaserHybrid welding
process or protected with a certified cover.
Keep suitable, tested fire extinguishers on hand.
Sparks and pieces of hot metal may also get into surrounding areas through small cracks
and openings. Take appropriate measures to ensure that there is no risk of injury or fire.
Do not undertake welding in areas at risk of fire and explosion, or on sealed tanks, drums,
or pipes if these have not been prepared in accordance with corresponding national and
international standards.
Do not undertake welding on containers in which gases, fuels, mineral oils, and the like are/
were stored. Residues pose a risk of explosion.
Danger from
Welding Current
An electric shock can be fatal. Every electric shock poses a risk of death.
All welding power-leads must be secured, undamaged, and insulated. Replace loose con-
nections and scorched cables immediately.
Stray Welding
Currents
If the following instructions are not observed, stray welding currents may occur, which can
result in the destruction of ground conductors, the power source used, the LaserHybrid
head, and other electrical equipment.
Ensure that the workpiece terminal is securely connected to the workpiece. If the floor is
electrically conductive, set up the power source so that it is insulated wherever possible.
EMC Measures WARNING! Electromagnetic field! Electromagnetic fields may cause health problems
that are not yet known.
The operator is responsible for ensuring that there is no electromagnetic interference with
electrical and electronic equipment.
If electromagnetic interference is discovered, the operator is obliged to take action to rectify
the situation.

11
EN-US
Check and evaluate possible problems and the interference immunity of equipment in the
vicinity according to national and international regulations:
- Safety devices
- Grid power lines, signal lines, and data transfer lines
- EMC and telecommunications equipment
- Devices for measuring and calibrating
- The health of persons close by, e.g., those with pacemakers and hearing aids
Persons with pacemakers must seek advice from their doctor before staying in the imme-
diate vicinity of where the welding work is taking place.
Supporting measures to avoid EMC problems:
a) Grid power supply
- If electromagnetic interference occurs despite a grid connection that complies
with regulations, take additional measures (e.g., use a suitable grid filter).
b) Welding power-leads
- Keep them as short as possible
- Route them close together (also to avoid EMC problems)
- Route them far from other lines
c) Equipotential bonding
d) Workpiece grounding
- If necessary, establish grounding using suitable capacitors
e) Shield, if necessary
- Shield other devices in the vicinity
- Shield the entire welding installation
Particular Hazard
Areas
Laser beam poses a risk of injury to the eyes. In addition to using the protective shield with
a regulation-compliant UV filter insert, eyes should be protected from laser beams using
regulation-compliant safety glasses for lasers. It must still be ensured, however, that no
one can accidentally look into the laser beam.
If the workpiece surface is especially bright or highly reflective, reflected laser-scattering
radiation poses a further risk. Take suitable precautions so that persons present have ad-
equate protection from laser-scattering radiation also.
Keep hands, hair, loose clothing, and tools away from moving parts, such as:
- Ventilators
- Gear wheels
- Rollers
- Shafts
- Wirespools and welding wires
Do not insert body parts into rotating gear wheels on the wire drive or into rotating drive
parts.
Covers and side parts must only be opened/removed during maintenance and repair work.
During operation:
- Ensure that all covers are closed and all side parts have been mounted properly.
- Keep all covers and side parts closed.
Welding wire from the welding torch poses a high risk of injury (cuts to the hand, injuries to
the face and eyes, etc.).
For this reason, always hold the welding torch away from your body (devices with wirefeed-
er) and wear suitable protective goggles.
Do not touch workpieces during or after welding – risk of burns.

12
Slag may fly off from workpieces that are cooling down. For this reason, be sure to wear
regulation-compliant protective equipment and ensure that other people are sufficiently
protected even when reworking workpieces.
Leave the welding torch and other parts with a high operating temperature to cool before
working on them.
Special regulations apply in areas where there is a risk of fire or explosion
– observe relevant national and international regulations.
Power sources for work in spaces where electrical hazards pose a greater risk (e.g. the
boiler room) must be marked with a (Safety) sign. The power source should not be located
in these types of spaces, however.
Risk of scalding due to coolant leakage. Before disconnecting connections for the coolant
supply hose or return connection, switch off the cooling unit.
When handling coolants, observe the specifications on the safety data sheet. The coolant
safety data sheet is available from your service center or from the manufacturer's homep-
age.
Only use suitable load-carrying equipment from the manufacturer for transporting devices
by crane.
- Attach chains or ropes to all designated suspension points on suitable load-carrying
equipment.
- Chains or ropes must be as close to perpendicular as possible.
- Remove the gas cylinder and wirefeeder (MIG/MAG and TIG devices).
Always use a suitable wirefeeder hoisting attachment with insulation on the crane for hoist-
ing the wirefeeder (MIG/MAG and TIG devices).
If the device is fitted with a carrier belt or handle, this should be used exclusively for trans-
portation by hand. The carrier belt is not suitable for transportation by crane, counterbal-
anced lift truck or other mechanical chain hoists.
All lifting equipment (belts, straps, chains, etc.) used in connection with the device or its
components must be checked regularly (e.g., for mechanical damage, corrosion, or chang-
es due to other environmental influences).
The test interval and scope must, as a minimum, comply with the respective valid national
standards and guidelines.
There is a risk of colorless, odorless shielding gas escaping without notice if an adapter is
used for the shielding gas connection. Use suitable Teflon tape to seal the thread of the
shielding gas connection adapter on the device side before installation.
Informal Safety
Measures
The Operating Instructions must always be at hand wherever the LaserHybrid head is be-
ing used.
In addition to the Operating Instructions, all applicable local rules and regulations regarding
accident prevention and environmental protection must also be made available and be fol-
lowed.
All safety and danger notices on the LaserHybrid head must be kept in a legible state.

13
EN-US

- be light-proof in relation to surrounding rooms
- is shielded with at least 1 mm steel plate and/or approved laser protective glass to pro-
tect against UV and laser beams
- The laser welding process and the arc welding process must be stopped automatically
and immediately as soon as the cell is opened.
A toppling device can be deadly! Set up the device securely on an even, solid surface
- A tilt angle of no more than 10° is permitted
Special regulations apply in areas at risk of fire or explosion
- Follow the appropriate national and international regulations.
Use instructions and checks within the company to ensure that the vicinity of the workplace
is always clean and organized.
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 an all-round clearance of 0.5 m (1 ft. 7.69 in.) so that
the cooling air can enter and leave unhindered.
Take care to ensure that the applicable national and regional guidelines and accident pre-
vention regulations are observed when transporting the device, especially guidelines con-
cerning hazards during transport and shipment.
Before transporting the device, always completely drain the coolant and dismantle the fol-
lowing components:
- Wirefeeder
- Wirespool
- Shielding gas cylinder
It is essential to conduct a visual inspection of the device to check for damage after it has
been transported but before it is commissioned. Have any damage repaired by trained ser-
vice technicians before commissioning the device.
Safety Measures
in Normal Opera-
tion
Only operate the LaserHybrid head if all protective and safety devices are fully functional.
If the safety devices are not fully functional, there is a risk of
- injury or death to the operator or a third party,
- damage to the device and other material assets belonging to the operating company,
- inefficient operation of the device.
Safety devices that are not fully functional must be repaired before the device is switched
on.
Never bypass or disable safety devices.
Before conditioning the LaserHybrid head, ensure that no one can be put in danger.
The LaserHybrid head must be examined at least once a week for externally detectable
damage and functionality of the safety devices.
Safety Inspection The operator is required to have the LaserHybrid head tested by an electrician after every
alteration, installation or modification, and all repairs and maintenance, and at least every
12 months, to ensure that it is in its correct state.
