THE ART OF WELDING
P6 HW
PN-0110008 Rev. 12 9-100
Devices for isolating energy sources 1. 4. 5.
Provision of shut off devices
Isolation devices (electrical, hydraulic, pneumat-
ic, ...) are mandatory. If they do not form part of
the POLYSOUDE supply (as is the case with porta-
ble installations), 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 explosion 1. 4. 6.
Welding equipment must not be used on premises
where in fl 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 fumes 1. 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 nding 1. 4. 8.
Only a quali fi 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 the
mains supply must be disconnected and a waiting
period of 2 minutes must be elapsed. These instruc-
tions are speci fi 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 disconnected
from the mains. A capacitor
can store its voltage for a
long time after it has been
disconnected from the power
supply.
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 solvents or fl ammable solvents
in the workshop. The electric arc could ignite the
vapours or fl ammable liquids.
During fault fi nding and maintenance work on
electrical equipment, take off any jewellery (rings,
watches, bracelets, etc.). Insulating shoes must be
worn when the situation requires it.
