SAFETY INSTRUCTIONS SAFETY INSTRUCTIONS SAFETY INSTRUCTIONS
In its conception, specification of parts and production, this machine is in compliance with regulation in force,
namely the European Standards (EN) and internationals (IEC).
There are applicable the European Directives "Electromagnetic compatibility" and "Low voltage", as well as
the standards IEC 60974-1 / EN 60974-1 and IEC 60974-10 / EN 60974-10.
1.1 ELECTROMAGNETIC COMPATIBILITY
The user is responsible for installing and using the arc welding equipment according to the
manufacturer's instructions. If electromagnetic disturbances are detected, then it shall be the responsibility of
the user of the arc welding equipment to resolve the situation with the technical assistance of the
manufacturer. In some cases this action may be as simple as connect to earth the welding circuit. In other
cases it could involve constructing electromagnetic screens enclosing the welding power source and the work
complete with associated input filters. In all cases, electromagnetic disturbances shall be reduced to the
minimum to avoid troubles.
Before installing arc welding equipment the user shall make an assessment of potential
electromagnetic problems in the surrounding area. The following shall be taken into account:
a) Supply cables, control cables, signaling and telephone cables, above, below and adjacent to the arc
welding equipment;
b) Radio and television transmitters and receivers;
c) Computer and other control equipment;
d) Safety critical equipment, e.g. guarding of industrial equipment;
e) The health of the people around, e.g. the use of pacemakers and hearing aids;
f) Equipment used for calibration or measurement;
g) The immunity of other equipment in the environment. The user shall ensure that other equipment being
used in the environment is compatible. This may require additional protection measures;
h) The hour of day when welding or other activities are to be carried out.
1.1.1 Methods of reducing emissions
Connection to mains
Arc welding equipment should be connected to the input supply system according to the
manufacturer's recommendations. If interference occurs, it may be necessary to take additional precautions
such as filtering of the supply system. Consideration should be given to shielding the supply cable of
permanently installed arc welding equipment, in metallic conduit or equivalent. Shielding should be
electrically continuous throughout its length. The shielding should be connected to the welding power source
so that good electrical contact is maintained between the conduit and the welding power source enclosure.
Welding cables
The welding cables should be kept as short as possible and should be positioned close together,
running at or close to the floor level.
Equipotent bonding
Bonding of all metallic components in the welding installation and adjacent to it should be
considered. However, metallic components bonded to the work piece will increase the risk that the operator
could receive an electric shock by touching these metallic components and the electrode at the same time.
The operator should be insulated from all such bonded metallic components.
Connection to earth of the work piece
When the work piece is neither bonded to earth for electrical safety nor connected to earth because
of its size and position, e.g. ships hull or building steelwork, a connection bonding the work piece to earth
