which is operated with a leakage current of no more than 30 mA and
covers all mains-powered devices in close proximity.
The fault-circuit interrupter must be suitable for all types of current.
There must be means of rapid electrical isolation of the welding
power source or the welding circuit (e.g. emergency stop device)
which are easily accessible.
When using welders under electrically dangerous conditions, the
output voltage of the welder must not be greater than 113 volt when
idling (peak value). Based on the output voltage this welder may be
used in these conditions.
z Welding in tight spaces
When welding in tight spaces this may pose a hazard through
toxic gases (risk of suffocation).
In tight spaces you may only weld if there are trained individuals
in the immediate vicinity who can intervene if necessary.
In this case, before starting the welding procedure, an expert
must carry out an assessment in order to determine what steps
are necessary, in order to guarantee safety at work and which
precautionary measures should be taken during the actual welding
procedure.
z Total of no-load voltages
When more than one welding power source is operated at the
same time, their no-load voltages may add up and lead to an
increased electrical hazard. Welding power sources must be
connected in such a way that the danger is minimised.
The individual welding power sources, with their individual control
units and connections, must be clearly marked, in order to be able
to identify which device belongs to which welding power circuit.
z Protective clothing
At work, the welder must protect his/her whole body by using
appropriate clothing and face protection against radiations and
burns. The following steps must be observed:
Wear protective clothing prior to welding work
–
Wear gloves.
–
Open windows or use fans to guarantee air supply.
–
Wear safety goggles and face mask.
