WARNING
Risk of accidents due to non-compliance with the safety instructions!
Non-compliance with the safety instructions can be fatal!
• Carefully read the safety instructions in this manual!
• Observe the accident prevention regulations and any regional regulations!
• Inform persons in the working area that they must comply with the regulations!
Danger when coupling multiple power sources
!
Coupling multiple power sources in parallel or in series
has to be carried out by
qualified personnel and in accordance with the manufacturer's guidelines. Before
bringing the power sources
into service for arc welding
operations, a test has to verify
that they cannot exceed the maximum
allowed open
circuit voltage.
• Connection of the machine
may
be carried out by qualified personnel only!
• When decommissioning individual power
sources, all mains and welding current leads
have
to be safely disconnected from the welding system as a whole. (Danger due to inverse
voltages
!
)
• Do not couple welding machines with pole reversing switch (PWS series) or machines for
AC welding, as a minor error in operation can cause the welding voltages to be combined.
CAUTION
Smoke and gases!
Smoke and gases can lead to breathing difficulties and poisoning. In addition, solvent
vapour (chlorinated hydrocarbon) may be converted into poisonous phosgene due to
the ultraviolet radiation of the arc!
• Ensure that there is sufficient fresh air!
• Keep solvent vapour away from the arc beam field!
• Wear suitable breathing apparatus if appropriate!
Noise exposure!
Noise exceeding 70 dBA can cause permanent hearing damage!
• Wear suitable ear protection!
• Persons located within the working area must wear suitable ear protection!
Electromagnetic fields!
The power source may cause electrical or electromagnetic fields to be produced which
could affect the correct functioning of electronic equipment such as IT or CNC devices,
telecommunication lines, power cables, signal lines and pacemakers.
• Observe the maintenance instructions
> see 6.3 chapter
!
• Unwind welding leads completely!
• Shield devices or equipment sensitive to radiation accordingly!
• The correct functioning of pacemakers may be affected (obtain advice from a doctor if
necessary).
