SECTION 3:
INSTALLATION, OPERATION AND SETUP
3.01 Environment
This Power Source is 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 32 to 104° F (0 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 12" (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 EN 60529. This
provides adequate protection against solid objects
(greater than 1/2", 12mm), and direct protection
from vertical drops. Under no circumstances should
the Power Source be operated or connected in
a micro environment that will exceed the stated
conditions. For further information please refer to
EN 60529.
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.
WARNING
This equipment should be electrically
connected by a qualified electrician.
3.03 Ventilation
!
WARNING
Since the inhalation of welding fumes can
be harmful, ensure that the welding area is
effectively ventilated.
3.04 Electricity Supply Voltage
The Electricity Supply voltage
should be within 208-265V
AC. Too low a voltage may
cause poor welding performance in STICK mode. 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.
