8) WARNINGS, PRECAUTIONS AND
GENERAL NOTICES FOR PERFORMING
REPAIRS
Repairs must be performed by qualified personnel only.
Before performing the repair, you should read and assimilate the
contents of this manual, in particular the safety precautions.
Avoid performing repairs without the presence of another per-
son able to provide help in the event of an accident.
The repair of a machine requires access to its internal parts
and consequently removal of some of the protective panels.
Additional precautions are therefore necessary with respect to
use of the machine for welding in order to prevent possible
injury or damage caused by contact with:
- live parts
- moving parts
- parts at high temperature
CAUTION
LIVE PARTS
When handling internal parts of the machine, remember that
opening of the switch does not prevent the risk of electric shocks:
the machine must be unplugged from the power supply.
Wait approx. one minute before carrying out work on the inter-
nal parts as the capacitors may be loaded at high voltage.
CAUTION
MEASURING INSTRUMENT LEAD'S LIVE PARTS
When taking measurements, remember that the measuring
instruments can be live and you should therefore avoid touching
their metal parts.
CAUTION
MOVING PARTS
Keep your hands well away from the fan when the machine
is connected to the power supply. Ensure that the machine is
unplugged and that the fan is at a standstill before replacing it.
CAUTION
PARTS AT HIGH TEMPERATURE
When handling internal parts of the machine, remember that
some of them may be very hot. In particular avoid contact with
heat sinks.
