EMC and EMI
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.
Examine and evaluate any possible electromagnetic problems that may
occur on equipment in the vicinity, and the degree of immunity of this
equipment, in accordance with national and international regulations:
- safety features
- mains, signal and data-transmission leads
- IT and telecoms equipment
- measurement and calibration devices
Ancillary measures for preventing EMC problems:
a) Mains supply
- If electromagnetic interference still occurs, despite the fact that the mains
connection is in accordance with the regulations, take additional
measures (e.g. use a suitable mains filter).
b) Welding cables
- Keep these as short as possible
- Arrange them so that they run close together (to prevent EMI problems
as well)
- Lay them well away from other leads.
c) Equipotential bonding
d) Workpiece grounding (earthing)
- where necessary, run the connection to ground (earth) via suitable
capacitors.
e) Shielding, where necessary
- Shield other equipment in the vicinity
- Shield the entire welding installation.
Electromagnetic fields may cause as yet unknown damage to health.
- Effects on the health of persons in the vicinity, e.g. users of heart pace-
makers and hearing aids
- Users of heart pacemakers must take medical advice before going
anywhere near welding equipment or welding workplaces
- Keep as much space as possible between welding cables and head/body
of welder for safety reasons
- Do not carrywelding cables and hose pack over shoulder and do not loop
around body or or any part of body
Keep your hands, hair, clothing and tools well away from all moving parts,
e.g.:
- fans
- toothed wheels, rollers, shafts
- wire-spools and welding wires
Do not put your fingers anywhere near the rotating toothed wheels of the
wirefeed drive.0
Covers and sideguards may only be opened or removed for as long as is
absolutely necessary to carry out maintenance and repair work.
