EMC Measures 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 operating company is obliged to take appropriate ac-
tion to rectify the situation.
Check and evaluate possible problems and the interference immunity of equip-
ment in the vicinity according to national and international regulations:
-
Safety devices
-
Grid power lines, signal lines, and data transfer lines
-
EMC and telecommunications equipment
-
Devices for measuring and calibrating
Supporting measures to avoid EMC problems:
1.
Grid power supply
-
If electromagnetic interference occurs despite a grid connection that
complies with regulations, take additional measures (e.g., use a suitable
grid filter).
2.
Control lines
-
Keep them as short as possible
-
Route them close together (also to avoid EMF problems)
-
Route them far from other lines
3.
Equipotential bonding
4.
Shield, if necessary
-
Shield other devices in the vicinity
-
Shield the entire welding installation
EMF measures Electromagnetic fields may cause health problems that are not yet known:
-
Effects on the health of persons close by, e.g., those with pacemakers and
hearing aids
-
Persons with pacemakers must seek advice from their doctor before staying
in the immediate vicinity of the device and the welding process
-
Keep distances between welding power-leads and the head/torso of the
welder as great as possible for safety reasons
-
Do not carry welding power-leads and hosepacks over your shoulder or wrap
them around your body or body parts
Safety Measures
at the Setup
Location and
during Transport
A toppling device can be deadly! Install the device horizontally on a flat, stable
surface free of vibration, anchor it securely on the surface, and secure against
toppling.
Special regulations apply in areas at risk of fire or explosion
-
Follow the appropriate national and international regulations.
Use instructions and checks within the company to ensure that the vicinity of the
workplace is always clean and organized.
Take care to ensure that the applicable national and regional guidelines and acci-
dent prevention regulations are observed when transporting the device, espe-
cially guidelines concerning hazards during transport and shipment.
It is essential to conduct a visual inspection of the device to check for damage
after it has been transported but before it is commissioned. Have any damage re-
paired by trained service technicians before commissioning the device.
