GB/IE/NI 13
Even a metal conductor or scaffolding can create an environment
with increased electrical hazard.
When using plasma cutters under electrically dangerous conditions,
the output voltage of the plasma cutter must not be greater than
113V when idling (peak value). The plasma cutter may not be used
in these cases due to the output voltage.
zPlasma 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 individuals 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 guarantee safety at work and which precautionary measures
should be taken during the actual cutting procedure.
zTotal of no-load voltages
When more than one plasma power source is operated at the same
time, their no-load voltages may add up and lead to an increased
electrical hazard. 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.
zUsing shoulder straps
The plasma cutter must not be used if the device is being carried e.g.
with a shoulder strap or handle. This is intended to prevent:
The risk of losing your balance if the lines or hoses which are
connected are pulled.
The increased risk of an electric shock as the operator comes into
contact with the earth if he/she is using a Class I plasma cutter,
thehousing of which is earthed through its conductor.
zProtective clothing
At work, the operator 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 cutting work.
– Wear gloves.
