Welding In Tight Spaces; Total Of Open Circuit Voltages; Using Shoulder Straps - Parkside PISG 120 B3 Operation And Safety Notes

Safety instructions
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 cir-
cuit (e.g. emergency stop device)
which are easily accessible.
When using welding devices
under electrically dangerous
conditions, the output voltage
of the welding device must be
greater than 113 volt when idling
(peak value). Based on the output
voltage this welding device may
be used in these conditions.

Welding in tight spaces

z
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 individu-
als 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 neces-
sary, in order to guarantee safety

at work and which precautionary
measures should be taken during
the actual welding procedure.

voltages
When more than one welding
power source is operated at the
same time, their open circuit
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 indi-
vidual 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.

Using shoulder straps

z
Welding must not take place if the
welding power source is being
carried 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
The increased risk of an

electric shock as the welder
