2.4.3 Hazards from elecromagentic disturbances
WARNING!
This Class A equipment is not intended for use in residential
locations where the electrical power is provided by the public low-voltage
supply system. There may be potential difficulties in ensuring electro-
magnetic compatibility in those locations, due to conducted as well as
radiated disturbance.
Electromagnetic disturbances are produced during the operation of welding
machines. The welding machines are designed to be used in industrial envi-
ronment. Their use in residential premises may cause interference with radio
and television reception.
The field intensity is particularly high in the immediate vicinity of the weld-
ing workplace so that the function of electronic equipment (IT systems, CNC
appliances etc.) may be affected. Therefore users of so-called active implants
– persons with heart pacemakers, heart defibrillators, insulin pump and other
similar implants – are not allowed to work on resistance spot welding ma-
chines!
Always remember that this type of machine produces powerful magnetic
fields that have a strong force of attraction on magnetic metals and could
damage watches, magnetic stripe cards and magnetic data carriers. Users of
heart pacemakers have to take medical advice before going anywhere near
welding equipment or welding workplaces. Contrary to the strong magnetic
fields being produced along the cables of conventional welding guns, the
transformer gun only produces very weak magnetic fields along its cables:
approx. 2 % compared to conventional guns.
The staff must wear safety goggles and safety gloves. Rings, watches and
clothing with metallic accessories must be avoided.
The persons involved in the work on the machine must be protected against
flying sparks.
To maintain the immunity to electromagnetic inferences and compatibility
(EMC), you are responsible in your capacity as owner/operator of ensuring
that
your machine is only connected to suitably grounded power supply
system
