In practice, various models of active implants are used, the
threshold values of which depend on different parameters (type
of implant, operating mode, programming of the implant).
As far as the occupational safety is concerned, an individual
risk assessment is recommended in each individual case. If
this is not possible, the generally valid safety values - which
are based on the most sensible implants - can be applied,
according to standard EN DIN VDE 0848-3-1 "Safety in electric,
magnetic and electromagnetic fields - Protection of persons
with active physical aids".
3.3.2. High frequency electromagnetic compatibility
EMC machine classification in accordance with standard EN
60974-10 (see type plate or the specification of technical
data).
Class B machines meet the EMC requirements in industrial
and residential areas, including residential areas connected
to the public low voltage supply network.
Class A machines are not intended for use in residential areas
where electric energy is drawn from the public low voltage
supply network. It is difficult to guarantee electromagnetic
compatibility for class A machines due to conducted emissions
and radiated interferences in these areas.
3.3.3. Radiation
Ultraviolet and infrared radiation are released during
welding.
• Protect skin and particularly the eyes. Keep eye drops and
skin cream with a high sun protection factor available.
• Always use safety glasses according to DIN EN 166 and
DIN EN 379 in your welder’s protective shield or helmet.
• Protect other persons in the vicinity of the welding area
from UV rays and spatter by suitable, non-flammable par-
tition walls.
• Always wear safety glasses with side protection when you
are in an area where welding takes place or where slag is
removed.
