EMC precautions

Particular danger
spots
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 welding workplaces
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
Do not touch the workpiece during or after welding - risk of injury from
burning!
Special regulations apply to rooms at risk from fire and/or explosion.
Observe all relevant national and international regulations.
Power sources for use in spaces with increased electrical danger (e.g.
boilers) must be identified by the
Welding-joins to which special safety requirements apply must only be
carried out by specially trained welders.
When using a testing unit for the insulation test, never touch the test-prods
(high voltage).
