TRANSMIG VAF4
Manual 0-5231 3-1 INSTALLATION, OPERATION AND SETUP
3.01 Environment
These units are designed for use in environments with
increased hazard of electric shock as outlined in IEC
60974.5.
A. Examples of environments with increased hazard of
electric shock are:
1. In locations in which freedom of movement is re-
stricted, so that the operator is forced to perform
the work in a cramped (kneeling, sitting or lying)
position with physical contact with conductive parts.
2. In locations which are fully or partially limited by
conductive elements, and in which there is a high
risk of unavoidable or accidental contact by the
operator.
3. In wet or damp hot locations where humidity or per-
spiration considerably reduces the skin resistance
of the human body and the insulation properties of
accessories.
B. Environments with increased hazard of electric
shock do not include places where electrically conduc-
tive parts in the near vicinity of the operator, which can
cause increased hazard, have been insulated.
3.02 Location
Be sure to locate the wirefeeder according to the fol-
lowing guidelines:
A. In areas, free from moisture and dust.
B. Ambient temperature between 0° C to 40° C.
C. In areas, free from oil, steam and corrosive gases.
D. In areas, not subjected to abnormal vibration or
shock.
E. In areas, not exposed to direct sunlight or rain.
F. The enclosure design of this Wire Feeder meets the
requirements of IP23S as outlined in AS 60529. This
provides adequate protection against solid objects
(greater than 12mm), and direct protection from
vertical drops. Under no circumstances should the
unit be operated or connected in a micro environ-
ment that will exceed the stated conditions. For
further information please refer to AS 60529.
G. Precautions must be taken against the Wire Feeder
toppling over. The Wire Feeder must be located on
a suitable horizontal surface in the upright position
when in use.
SECTION 3: INSTALLATION, OPERATION AND SETUP
3.03 ventilation
!
WARNING
Since the inhalation of welding fumes can
be harmful, ensure that the welding area is
effectively ventilated.
3.04 Mains Supply voltage
Requirements
CAUTION
This wirefeeder cannot be connected directly
to the mains supply. It must be connected
to a suitable wirefeeder control socket on a
power source.
3.05 Electromagnetic Compatibility
!
WARNING
Extra precautions for Electromagnetic
Compatibility may be required when this
Welding Power Source is used in a domestic
situation.
A. Installation and Use - Users Responsibility
The user is responsible for installing and using the
welding equipment according to the manufacturer’s
instructions. If electromagnetic disturbances are
detected then it shall be the responsibility of the user
of the welding equipment to resolve the situation with
the technical assistance of the manufacturer. In some
cases this remedial action may be as simple as earthing
the welding circuit, see NOTE below. In other cases it
could involve constructing an electromagnetic screen
enclosing the Welding Power Source and the work,
complete with associated input filters. In all cases,
electromagnetic disturbances shall be reduced to the
point where they are no longer Trouble-some.
NOTE
The welding circuit may or may not be
earthed for safety reasons. Changing the
earthing arrangements should only be au-
thorised by a person who is competent to
assess whether the changes will increase the
risk of injury, e.g. by allowing parallel weld-
ing current return paths which may damage
the earth circuits of other equipment. Further
guidance is given in IEC 60974-13 Arc Weld-
ing Equipment - Installation and use (under
preparation).
