THE ART OF WELDING
Check always for voltage-
free parts, even if the instal-
lation has been disconnected
from the mains. A capacitor
can store its potential for a
long period of time after it
has been separated from the
power supply.
Never shunt or eliminate safety devices or interlocks
installed to protect the user or operator of the equip-
ment.
Never stand on a wet or humid fl oor during interven-
tions on electric or electronic devices. Avoid impera-
tively any leakage of liquids inside electric or elec-
tronic equipment.
2. General information
Applicable directives
2004/108/EC Electromagnetic compatibility
2006/95/EC Electrical equipment designed for use certain voltage limits
Never use volatile solvents or fl ammable substances
next to welding machinery. The electric arc could ac-
cidentally ignite the vapours or combustible liquids.
During repair and maintenance work on electric or
electronic equipment, take off any jewellery (rings,
watches, bracelets, etc.). Insulating shoes must be
made available under the responsibility and on the
expenses of the operating company, they must be
worn by the concerned staff whenever it is neces-
sary.
