EMC precautions
It is the responsibility of the owner/operator to ensure that no
electromagnetic interference is caused to electrical and electronic
equipment.
If electromagnetic interference is found to be occurring, the owner/operator
is obliged to take all necessary measures to prevent this interference.
Evaluation of possible electromagnetic problems that may occur on
equipment in the vicinity, and of the degree of immunity of this equipment as
per the CE Declaration of Conformity:
- safety features
- mains, signal and data-transmission leads
- IT and telecoms equipment
- measurement and calibration devices
- the health of persons in the vicinity, e.g. users of heart pacemakers and
hearing aids
- users of heart pacemakers must take medical advice before going
anywhere near the welding workplace
Ancillary measures for preventing EMC problems:
a) Mains supply
- If electromagnetic interference still occurs, despite the mains connection
being in accordance with the regulations, take additional measures (e.g.
mains filter)
b) Welding cables
- Keep these as short as possible
- Arrange them so that they run close together
- Lay them well away from other leads
c) Equipotential bonding
d) Workpiece earthing
- where necessary, run the connection to earth via suitable capacitors
e) Shielding, where necessary
- Shield other equipment in the vicinity
- Shield the entire welding installation
