2.4 Electromagnetic fields - implants
Instructions for operating companies of stud welding devices in
accordance with DIN EN IEC 60974-9:2019-03 (extract):
Electric current flowing through a conductor causes locally limited electric and
magnetic fields (EMFs). All welders should apply the following procedures to
minimise the hazards which are related to the exposure to electric and magnetic
fields from the welding current circuit:
• Bundle the welding cables; if possible, secure them with a strap;
• Keep your body away from the welding current circuit as far as possible;
• Never wrap the welding cables around your body;
• Do not bring your body between the welding cables; keep both welding cables
on one side of your body; connect the return circuit to the workpiece as closely
as possible in the area in which the welding work is carried out;
• Do not work, sit or lean against something next to the welding power source;
• Do not weld when carrying the welding power source or wire feeder.
Electric and magnetic fields may interfere with portable medical devices and
implants. For people with portable medical devices and implants, protective
measures must be taken. These include, for example, access restrictions for
passers-by or individual risk assessments for welders. Risk assessments and
recommendations for people with medical devices and implants must be carried
out by a doctor.
Danger from magnetic fields
In the area surrounding the device, strong magnetic fields which may influ-
ence medical auxiliary devices and therefore result in danger to life occur
during the welding process.
• Please observe the following instructions from the
DIN EN IEC 60974-9:2019-03 standard.
