INSTALLATION/SETUP TRANSMIG 250i
Manual 0-5187 3-1 INSTALLATION/SETUP
3.01 Environment
These units are designed for use in environments with
increased hazard of electric shock as outlined in AS
60974.1 and AS 1674.2. Note the Transmig 250i Plant Part
No. W1003250M (Asia Version) has the VRD turned OFF.
Additional safety precautions may be required when using
unit in an environment with increased hazard of electric
shock. Please refer to relevant local standards for further
information prior to using in such areas.
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 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 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.
SECTION 3: INSTALLATION OPERATION AND SETUP
G. The enclosure design of this power source meets the
requirements of IP23S as outlined in AS60529. This
provides adequate protection against solid objects
(greater than 12mm), and direct protection from verti-
cal drops. Under no circumstances should the unit be
operated or connected in a micro environment that will
exceed the stated conditions. For further information
please refer to AS 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 Mains Supply Voltage
Requirements
The Mains supply voltage
should be within ± 15% of the rated Mains supply volt-
age. Too low of a supply voltage may cause poor welding
performance or wirefeeder malfunction. Too high of a
supply voltage will cause components to overheat and
possibly fail.
