H) Moving parts can cause damage
Moving parts, such as the fan, can cut fingers and
hands and catch clothes.
Keep all doors, covers and guards closed and securely
in place.
Protections and coverings can be removed, for possible
maintenance and checks, only by qualified personnel.
Keep hands, hair, loose clothing and tools away from
moving parts.
Refit the covers and guards and close the doors when
the operation is completed and before restarting the
machine.
I) Noise
These welders do not in themselves produce any
noise exceeding 70 dB. Arc welding processes can
produce noise levels above this limit. Therefore, users
must implement the precautions required by law.
Ear plugs should be used when working overhead or
in a small space.
A rigid helmet should be used when others work in
the area above.
Welders should not use flammable hair products.
WARNINGS ABOUT ELECTROMAGNETIC COMPAT-
IBILITY
Although these welding machines have been built
according to the regulations, they can generate elec-
tromagnetic disturbances, that is disturbances to the
telecommunication systems (telephone, radio, televi-
sion) or to the control and safety systems. Read the
instructions carefully to eliminate or minimise inter-
ference.
ATTENTION: the welding machine has been de-
signed to work in an industrial environment,
therefore, to operate in domestic environments it
may be necessary to observe special precautions
in order to avoid possible electromagnetic inter-
ference.
You must install and use the welding machine accord-
ing to the manufacturer's instructions. If electromag-
netic interference is detected, countermeasures must
be taken to eliminate the problem, possibly using the
manufacturer's technical assistance. In any case, do
not modify the welding machine without the manu-
facturer's approval.
Work area control to prevent E.M. interference
Before installing the welding machine it is necessary
to check the work area to detect the existence of ser-
vices that could malfunction in the event of electro-
magnetic disturbances.
radiation emitted by the electric arc, by sparks and
slag from molten metal, using fireproof clothing,
which covers all exposed surfaces of the body.
Wear protective clothing and welder gloves, head-
gear and high shoes with safety tip. Button the shirt
collars and pocket flaps and wear trousers without
cuff to avoid the entry of sparks and slag.
Wear a mask with protective glass on the outside and
adiactinic glass filter inside. This is MANDATORY for
welding operations, in order to protect the eyes from
radiant energy and volatile metals. Replace the pro-
tective glass if it is broken, pitted or spotted. Avoid
oily or greasy clothes; a spark could ignite them. In-
candescent metal parts, such as work pieces, should
always be handled with gloves.
First aid equipment and a qualified person should be
available for each shift, unless there are health facili-
ties nearby for immediate treatment of eye and skin
burns.
G) Fumes
Welding operations produce harmful fumes and met-
al dust, which can damage health:
- Do not work in spaces without adequate ventila-
tion. Keep your head out of the fumes.
- In closed environments, use suitable exhaust fans.
If ventilation is not adequate, use suitable respi-
rators.
- Clean the material to be welded if there are solvents
or halogen degreasers, which give rise to toxic gas-
es. During welding, some chlorinated solvents can
decompose in the presence of radiation emitted by
the electric arc and produce phosgene gas.
- Do not weld coated metals or those containing lead,
graphite, cadmium, zinc, chromium, mercury or be-
ryllium, unless a suitable respirator is available.
The electric arc generates ozone. Prolonged expo-
sure, in environments with high concentrations of
ozone, can cause headaches, irritation of the nose,
throat and eyes and severe congestion and chest
pain.
IMPORTANT: DO NOT USE OXYGEN FOR VENTILA-
TION!!!
Gas leaks must be avoided in small spaces. Large gas
leaks can dangerously change the oxygen concen-
tration.
Do not place cylinders in small spaces.
DO NOT WELD or cut where solvent vapours can
be drawn into the welding atmosphere or if radiant
energy can penetrate into atmospheres containing
even tiny amounts of trichloroethylene and perchlo-
rethylene.
