EMC CLASSIFICATION
This Class A machine is not intended to be used on a residential site where the electric current is
supplied by the domestic low-voltage power grid. There may be potential difficulties in ensuring
electromagnetic compatibility at these sites, due to conducted interferences as well as radiation.
GYSARC 80 / 100 / 120: This equipment does not comply with IEC 61000-3-12 and is intended to be
connected to private low-voltage systems interfacing with the public power grid only at the medium-
or high-voltage level. If it is connected to a public low-voltage power grid, the installer or user of the
machine has to ensure, by checking with the network operator, that the device can be connected.
GYSARC 160 / 200: This equipment does not comply with IEC 61000-3-12 and is intended to be
connected to private low-voltage systems interfacing with the public supply only at the medium- or
high-voltage level. On a public low-voltage power grid, it is the responsibility of the installer or user
of the device to ensure, by checking with the operator of the distribution network, which device can
be connected.
GYSARC 80 / 100/120: This equipment complies with the IEC 61000-3-11 standard.
GYSARC 160 / 200: Provided that the impedance of the low-voltage public electrical network at the
common coupling point is less than Zmax = 0.427 Ohms, this equipment complies with IEC 61000-3-
11 and can be connected to public low-voltage electrical mains. It is the responsibility of the installer or
user of the equipment to ensure, in consultation with the distribution netwtork operator if necessary,
that the network impedance complies with the impedance restrictions.
ELECTROMAGNETIC EMISSIONS
The electric current flowing through any conductor causes electrical and magnetic fields (EMF). The
welding current generates an EMF around the welding circuit and the welding equipment.
The EMF electromagnetic fields can interfere with certain medical implants, such as pacemakers. Protection measures
must be taken for people with medical implants. For example, by restricting access to passers-by or conducting an
individual risk evaluation for the welders.
All welders should take the following precautions in order to minimise exposure to the electromagnetic fields (EMF)
generated by the welding circuit:
• position the welding cables together – if possible, attach them;
• keep your head and torso as far as possible from the welding circuit;
• never wrap the cables around your body;
• never position your body between the welding cables. Hold both welding cables on the same side of your body;
• connect the earth clamp as close as possible to the area being welded;
• do not work too close, do not lean and do not sit on the welding machine
• do not weld when you're carrying the welding machine or its wire feeder.
People wearing pacemakers are advised to consult their doctor before using this device.
Exposure to electromagnetic fields while welding may have other health effects which are not yet
identified.
RECOMMENDATIONS TO ASSESS THE WELDING AREA AND WELDING INSTALLATION
Overview
The user is responsible for the installation and use of the arc welding equipment according to the manufacturer's
instructions. If electromagnetic disturbances are detected, the user is responsible for resolving the situation with the
manufacturer's technical assistance. In some cases, this corrective action may be as simple as earthing the welding
circuit. In other cases, it may be necessary to construct an electromagnetic shield around the welding power source and
around the entire piece by fitting input filters. In all cases, electromagnetic interferences must be reduced until they are
no longer inconvenient.
Welding area assessment
Before installing the machine, the user must evaluate the possible electromagnetic problems that may arise in the area
where the installation is planned. The following elements should be taken into account:
a) the presence (above, below and next to the arc welding machine) of other power cables, remote cables and telephone
cables;
b) television transmitters and receivers;
c) computers and other hardware;
