In workplaces which are
restricted completely or in
part in terms of electrical
conductivity and where there is
a high risk through avoidable
or accidental touching by the
operator;
In wet, humid or hot work-
places where the air humidity
or weld signifi cantly reduces
the resistance of human skin
and the insulating properties or
effect of protective equipment.
Even a metal conductor or
scaffolding can create an envi-
ronment with increased electrical
hazard.
When using plasma cutters under
electrically dangerous conditions,
the output voltage of the plasma
cutter must be greater than
48volt when idling (effective
value). The plasma cutter may not
be used in these cases due to the
output voltage.
Plasma cutting in tight
spaces
When welding and plasma
cutting in tight spaces this may
pose a hazard through toxic
gases (risk of suffocation). In tight
spaces the device may only be
operated if there are trained indi-
viduals in the immediate vicinity
who can intervene if necessary.
In this case, before starting to
use the plasma cutter, an expert
must carry out an assessment in
order to determine what steps
are necessary, in order to guar-
antee safety at work and which
precautionary measures should
be taken during the actual cutting
procedure.
Total of open circuit
voltages
When more than one plasma
power source is operated at the
same time, their open circuit
voltages may add up and lead
to an increased electrical haz-
ard. The plasma power sources
must be clearly marked with
their individual control units and
connections, in order to be able
to identify which device belongs
to which circuit.
Using shoulder straps
The plasma cutter must not be
used if the device is being car-
ried e.g. with a shoulder strap.
This is intended to prevent:
The risk of losing your balance
if the lines or hoses which are
connected are pulled.
