Requirements for operating staff
The operating staff must carefully read the Opera-
ting Instructions before using the appliance.
Since the use of the device if handled incorrectly can
entail considerable risks, only knowledgeable persons
may be entrusted with the use of it.
The operator must be appropriately trained in setting
up, operating and using the machine.
Qualification: Apart from the detailed instructions
by a professional, no special qualification is necessary
for appliance using.
Minimum age: Persons over 18 years of age can
only work on the appliance. An exception includes
youngsters trained in order to reach knowledge
under supervision of the trainer during occupational
education.
Training: Using the appliance only requires corres-
ponding training by a professional or the Operating
Instructions. No special training is necessary. The
operator is responsible for accidents or risks to third
parties.
Instructions for the installation and oper-
ation of an arc welding device to prevent
possible electromagnetic interference:
As the manufacturer, we recommend that the
following assessments and measures be carried
out by a qualified electrician.
General
The user is responsible for setting up and
operating the arc welding machines/cutting
equipment in accordance with the manufactur-
er's instructions. If electromagnetic interference
is detected, it is the responsibility of the user of
the arc welding machines/cutting equipment to
find a solution with the technical assistance of
the manufacturer. In some cases, the measure
needed may simply consist of earthing the
welding circuit (see note). In other cases, it may
include complete electromagnetic shielding of
the power source of the arc welding machine/
cutting equipment and the workpiece, com-
bined with input filters. In all cases, electromag-
netic interference must be reduced until it no
longer causes any disturbance.
Note
The approach taken to earthing the welding
circuit depends on the local safety regulations.
Changing the earthing to improve electromag-
netic compatibility may increase the risk of
accidents or damage to equipment.
Assessing the surroundings
Before setting up the arc welding machines
and/or cutting equipment, the user must assess
possible electromagnetic problems in the sur-
roundings.
When doing so, the following factors must be
taken into account:
a) other mains cables, control cables, signal and
telecommunication cables above, below and
next to the arc welding machines and/or cutting
equipment;
b) Audio and television broadcast transmitters
and receivers;
c) Computers and other control devices;
d) Safety equipment, e.g. protection for com-
mercial facilities;
e) the health of persons nearby, e.g. those using
pacemakers and hearing aids;
f) Calibration and measurement equipment;
g) the resistance of other equipment in the
vicinity to interference. The user must ensure
that
other equipment used in the environment is
suitable for such a purpose. This may require
additional protective measures;
h) the time of day during which the welding,
cutting, or other activities must be carried out.
The extent of that surrounding area that must
be considered depends on how the building
is constructed, and the other activities taking
place there. This area may extend beyond the
limits of the premises
Evaluation of the welding machine / cutting
equipment
In addition to the assessment of the area, the
arc welding machines/cutting equipment can
be evaluated to assess and resolve cases of
interference. An assessment of electromagnetic
interference should include in situ measure-
ments, as specified in section 10 of CISPR
11:2009. In-situ measurements can also be
made to gauge the effectiveness of any minimi-
sation measures implemented.
Guidance for minimisation measures:
Public power supplies
Welders machines/cutting equipment should
be connected to the public power supply as per
the manufacturer's recommendations. If there
is any interference, it may be necessary to take
additional precautions, such as fitting filters for
the mains connection. Consider shielding the
mains cable of permanently installed welding
machines/cutting equipment with a metal pipe
or similar. The shielding should be electrically
connected for its entire length. The shielding
should be connected to the welding machine/
cutting equipment power source to achieve
good electrical contact between the sheath
and the housing of the welding machine/cutter
power source.
