1.5. Safety precautions
1.5.1. General rules
All aspects of work should be planned with
caution. To carry it out, safety related actions
are continuously required.
All hook up or maintenance operations
described in this manual, which may be
harmful, are always indicated by the
ATTENTION symbol.
Warning Situation with the risk to
injure persons or even
danger of life
Procedures to avoid malfunction or damage of
equipment are indicated by the mention Note.
1.5.2. Training of the operators
One copy of the operating and maintenance
manual is always delivered with the equipment.
The different operators (welder, controller,
maintenance people, ...) must always have at
their disposal at least one spare copy (respect
the copy right). The qualification they need for
their work depends on the level of
responsibility they carry during their mission.
1.5.3. Maintenance and adjustments
If maintenance or adjustment work has to be
carried out on the upper parts of the
equipment, a scaffold has to be erected.
It is strictly forbidden to pull on cables or hoses
to move welding heads or the power source or
to push on consoles or panels.
1.5.4. Ergonomics
! Identification
Identification by means of colours, especially
on safety relevant elements like buttons or pilot
lamps, must not be altered or changed.
Components with worn out colours have to be
replaced.
! Lighting of the work area
Lighting equipment should give regular light
without spots or too much light concentration.
Glare-free light without deep shadows can help
to avoid fatigue of the operators.
1.5.5. Protection during breakdown or
incidents
Before taking action in the case of a
breakdown or incident, the machines must be
disconnected from the power supply.
1.5.6. Electric disconnect or shut off
devices
! Disposition of equipment isolators
The presence of electric disconnect or shut off
devices is imposed by law. In case of mobile
equipment or when Polysoude supplies only a
part of the entire machine, the customer is
responsible to install the necessary missing
devices.
! Operation of electric disconnect or shut
off devices
Before electric disconnect or shut off devices
are operated, it has to be checked that this
action is of no danger for operators or visitors.
1.5.7. Fire prevention and explosion
protection
The working environment for the welding
machines must be free of combustible material
and solvents.
The PS 254 should never be used for the
purpose of defrosting.
1.5.8. Protection against burns
Operators and visitors must wear protection
against sparks.
1.5.9. Gases and vapors
A sufficient ventilation has to be installed in the
workshop to avoid health hazards caused by
gases or vapors generated during the weld
process. A protection against the radiation
emitted from the arc has to be worn.
