EMC MATERIAL 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 issues in ensuring electromagnetic compatibility on these sort of sites, due to conducted
interferences as well as radiation.
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 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.
ELECTROMAGNETIC INTERFERENCES
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. Protective measures must be taken for people having
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 upper body 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 welding area;
• do not work too close to, do not lean and do not sit on the welding machine
• do not weld when transporting 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 FOR WELDING AREA ASSESSMENT AND WELDING
Miscellaneous
The user is responsible for the correct installation and usage of the welding material based on the instructions supplied by the manufacturer. If
electromagnetic disturbances are detected, it is the user's responsibility to resolve 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 must 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;
d) critical safety equipment such as industrial machine protections;
e) the health and safety of people in the area especially if they are using pacemakers or hearing aids;
f) calibration and measuring equipment;
g) the isolation of other pieces of equipment which are in the same area.
The operator has to ensure that the devices and equipment used in the same area are compatible with each other. This may require extra precautions;
h) the time of day during the welding or other activities have to be performed.
The dimension of the cutting area that has to be considered depends on the size and shape of the building and the type of work undertaken. The area
taken into consideration might go beyond the limits of the installations.
Review of the welding installation
Reviewing the welding installations can be useful to determine and resolve any case of electrical disturbances. The assessment of emissions must
include in situ measurements as specified in Article 10 of CISPR 11: 2009. In situ measurements can also be used to confirm the effectiveness of
mitigation measures.
