Personal Protect-
ive 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
protection)
- 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 protection 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
accumulation of gases hazardous to health, risk of asphyxiation due to lack of oxy-
gen in the breathable air, hazards posed by laser light, etc.)
- provide protective equipment
- construct protective walls or install protective curtains.
Danger from
Toxic Gases and
Vapors
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
measured 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
Shielding gas is colorless and odorless and may suppress the oxygen in the ambient air
in the event of leakage.
8

- 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 cylin-
der 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
leakage 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 weld-
ing 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
connections 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 LaserHy-
brid 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 rec-
tify the situation.
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
9
EN-US

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).
a) Welding power-leads
- Keep them as short as possible
- Route them close together (also to avoid EMC problems)
- Route them far from other lines
a) Equipotential bonding
b) Workpiece grounding
- If necessary, establish grounding using suitable capacitors
a) 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
adequate 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
wirefeeder) and wear suitable protective goggles.
Do not touch workpieces during or after welding – risk of burns.
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.
