SECTION 3: INSTALLATION, OPERATION AND SETUP
3.01 Environment
This Power Source System 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 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 System 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 System 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
System 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 95-140V 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 System 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
The Firepower MST 140i must be electrically
connected by a qualified electrical trades-person.
Damage to the PCA (Power Control Assembly)
could occur if 140 VAC or higher is applied to the
Primary Power Cable.
WARNING
ELECTRIC SHOCK can kill; SIGNIFICANT DC
VOLTAGE is present after removal of input power.
DO NOT TOUCH live electrical parts.
SHUT DOWN welding Power Source, disconnect input power
employing lockout/tagging procedures. Lock-out/tagging
procedures consist of padlocking line disconnect switch in
open position, removing fuses from fuse box, or shutting off
and red-tagging circuit breaker or other disconnecting device.
