a) When welding electrical equipment
or machines ensure the workpiece
is disconnected from the mains.
Neglecting to do so can result in
the welding current damaging the
machine:
For example: if the earthing cable is
placed on the welder's housing, this will
create a electrical connection between
the welder and the workpiece. Only weld
a workpiece with an earth conductor
connected. It is possible to weld a
workpiece which has no eath conductor
attached. In this situation, the welding
current bypasses the earth conductor
and runs through to the workpiece.
The high welding current can cause the
earthing conductor to melt.
b) The supply line fuses for the mains
sockets have to meet the
(VDE 0100)
specifications. Only fuses or circuit
breakers meeting the necessary
requirements may be used (16A circuit
breaker). The fuses amperage rating
must not be too high in order to prevent
damage to the electrical lines.
Additional safety instructions for
connecting the welder to public
supply grid
High-power equipment can influence the
grid quality through the current they draw
from the grid. It is your responsibility to
ensure that the equipment can be connected.
When operating the welder, it may, in some
cases, cause electromagnetic interference,
although it complies with the emission
limits of the standard. As the user, you are
responsible for any disruptions caused by
welding. Selecting and connecting to the
supply network has to be done by qualified
personnel according to relevant national and
local regulations.
a) If necessary, consult your power supply
company.
b) Before starting work, assess any
possible electromagnetic problems
in the surrounding area (also see EN
60974-10, Annex A):
-
Power, control, signal and
telecommunication lines,
-
Radio, television,
-
Computer and other control devices,
-
Safety devices (alarm and fire alarm
systems),
-
the health of people nearby, e.g., if
they are wearing pacemakers or hearing
aids,
-
Calibration and measuring equipment,
-
the interference resistance of other
equipment in the area,
-
the time of day at which the work has to
be performed.
c) Take measures to reduce emissions,
such as:
-
additional mains filter or shielding the
mains connection using a metal tube,
-
Regular maintenance and inspection of
the welder,
-
Welding cables should be as short as
possible and close together and be
routed on or near the floor,
-
Potential equalisation on all metallic
parts in or near a welder, where a
complete isolation of the welder is
necessary,
-
Earthing the workpiece without
increasing the risk of accidents to the
welding personnel. If the workpiece
cannot be earthed directly, the
connection should be done using
suitable capacitors.
-
Shielding from other equipment and
lines in the surrounding, if necessary,
the entire welder.
-
EMC classification according to IEC
60974-10: Class A.
