EMC device clas-
sifications
EMC measures
EMF measures
Devices with emission class A:
- are only designed for use in an industrial setting
- can cause conducted and emitted interference in other areas.
Devices with emission class B:
- satisfy the emissions criteria for residential and industrial areas.
This also applies to residential areas in which power is supplied
from the public low-voltage grid.
EMC device classification according to the rating plate or the techni-
cal data.
In certain cases, even though a device complies with the standard limit values
for emissions, it may affect the application area for which it was designed (e.g.
when there is sensitive equipment at the same location, or if the site where the
device is installed is close to either radio or television receivers).
If this is the case, then the operator is obliged to take appropriate action to rec-
tify the situation.
Check for possible problems, and check and evaluate neighbouring devices'
resistance to interference according to national and international require-
ments:
- Safety features
- power, signal and data transfer lines
- IT and telecommunications devices
- measuring and calibrating devices
Supporting measures for avoidance of EMC problems:
a) Mains supply
- if electromagnetic interference arises despite correct mains connec-
tion, additional measures are necessary (e.g. use a suitable line fil-
ter).
b) Welding leads
- must be kept as short as possible
- must run close together (to avoid EMF problems)
- must be kept well apart from other leads
c) Equipotential bonding
d) Earthing the workpiece
- if necessary, establish an earth connection using suitable capacitors.
e) Shielding, if necessary
- shield off other nearby devices
- shield off entire welding installation
Electromagnetic fields may pose as yet unknown risks to health:
- effects on the health of others in the vicinity, e.g. wearers of pacemakers
and hearing aids
- wearers of pacemakers must seek advice from their doctor before ap-
proaching the device or any welding that is in progress
- for safety reasons, keep distances between the welding cables and the
welder's head/torso as large as possible
- do not carry welding cables and hosepacks over the shoulders or wind
them around any part of the body
