Welding cables
Welding cables should be as short as possible, close
together, and should run across or near
the ground.
Electrical bonding
The electrical interconnection of all metallic parts in
and next to a welding machine/cutting equipment
should be taken into consideration. Metallic parts
connected to the workpiece can increase the risk of
the welder receiving an electric shock from touching
these metallic parts and the electrode at the same
time. The welder should be electrically insulated from
all of these connected metal parts.
Earthing the workpiece
It may be that the workpiece is not already connected
to earth for reasons of electrical safety or because of
its size and location, e.g. a ship's hull or steel struc-
tures. If so, grounding the workpiece can reduce emis-
sions in some, but not all, cases. Ensure that earthing
the workpiece does not increase the risk of accident
for the user or cause the destruction of other electri-
cal equipment. If necessary, the workpiece must be
grounded by a direct connection to the workpiece. In
countries where a direct connection is prohibited, the
connection should be achieved using suitable capaci-
tors, selected in accordance with national regulations.
Screening
Selective screening of other cables and equipment in
the vicinity can reduce irradiation. The screening of
the entire welding/cutting set-up may be considered
for
special applications.
Class A (IEC 60974-10):
If you intend to use the apparatus in residential sur-
roundings supplied by the low voltage mains supply,
an electromagnetic filter may be required to suppress
electrical disturbance to a level where they will no
longer be a nuisance to the user.
The apparatus may be used in industrial or other
areas where power is not supplied by municipal LV
mains.
Class A apparatus are not intended for use in residen-
tial areas where power is supplied via municipal LV
mains, since unfavourable power conditions may cau-
se interference. As a user, you must make sure, after
consultation with your energy provider, if necessary,
that your point of connection on which the machine
is to be operated meets the requirements above.
The user is responsible for faults arising from the
welding.
