SECTION 3:
INSTALLATION
H. Precautions must be taken against the power
source toppling over. The power source must be
located on a suitable horizontal surface in the
upright position when in use.
3.03 Ventilation
Since the inhalation of welding fumes can be harmful,
ensure that the welding area is effectively ventilated.
3.04 Mains Supply Voltage
Requirements
The Mains supply voltage should be within •± 15% of
the rated Mains supply voltage. Too low a voltage may
cause poor welding performance. Too high a supply
voltage will cause components to overheat and
possibly fail.
The Welding Power Source must be:
• Correctly installed, if necessary, by a qualified
electrician.
• Correctly earthed (electrically) in accordance
with local regulations.
• Connected to the correct size power point and
fuse as per the Specifications on page 2-4.
!
WARNING
Any electrical work must be carried out
by a qualified Electrical Tradesperson.
3.01 Environment
These units are designed for use in environments with
increased hazard of electric shock.
A. Examples of environments with increased hazard
of electric shock are:
1. In locations in which freedom of movement
is restricted, 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 perspiration considerable 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
conductive parts in the near vicinity of the operator,
which can cause increased hazard, have been
insulated.
3.02 Location
Be sure to locate the welder according to the following
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. Place at a distance of 300mm or more from walls
or similar that could restrict natural air flow for
cooling.
G. The enclosure design of this power source meets
the requirements of IP23S as outlined in AS
60529. This provides adequate protection against
solid objects (greater than 12mm), and adequate
protection against liquids sprayed directly at 60°.
Under no circumstances should the unit be oper-
ated or connected in a micro environment that
will exceed the stated conditions. For further in-
formation please refer to AS 60529.
