THE ART OF WELDING
P6
PN-0509076 Rev. 16 9-92
Device for isolating energy sources1. 4. 5.
Provision of shut-off devices
Isolation devices (electrical, hydraulic, pneumatic...)
are mandatory. If they do not form part of the POLYS-
OUDE supply (as is the case with portable installa-
tions), they MUST be provided by the user who must
install them at his cost and responsibility.
Operation of shut off devices
In accordance with the stipulations in the manufac-
turer’s technical manual, before actioning shut-off
devices (isolation of equipment from its source of
power), personnel must make sure that neither they
not any third party is in danger.
Prevention of fi re and explosion1. 4. 6.
Welding equipment must not be used on premises
where infl ammable, volatile or explosive products
are present. In no circumstances is the P6 power
source to be used to thaw pipework.
Preventing release of gas and fumes1. 4. 7.
It is the user’s responsibility to assess:
inconvenience or unhealthy conditions inside his •
workshop and to take the necessary measures to
apply this clause.
Protection against radiation from electric arcs.•
Safety instructions and protective arrangements •
must conform to NF EN 166 and NF EN 169.
Faultfi nding1. 4. 8.
Only a qualifi ed electrician is authorised to inspect,
test, adjust or repair electric or electronic equip-
ment.
Before any maintenance work can be carried out or
an instrument is connected to a circuit, the mains
supply must be disconnected and a waiting period of
2 minutes must have elapsed. These instructions are
specifi ed on the label at the right side of the power
source.
Always check that no voltage
is present even if the instal-
lation has been disconnec-
ted from the mains. A capa-
citor can store its voltage for
a long time after it has been
disconnected from the power
source.
Never shunt or remove the safety devices or inter-
locks installed to protect personnel.
Never stand on a wet or humid fl oor during inter-
vention on electric or electronic devices. It is essen-
tial to avoid any leakage of liquids inside electric or
electronic equipment.
Never use volatile or fl ammable solvents in the
workshop. The electric arc could ignite the vapours
or fl ammable liquids.
During faultfi nding and maintenance work on electri-
cal equipment, take off any jewellery (rings, watch-
es, bracelets, etc.). Insulating shoes must be worn
when the situation requires it.
