ESAB FABRICATOR 141i
Manual 0-5420 3-1 INSTALLATION, OPERATION AND SETUP
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 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
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 guide-
lines:
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 pro-
vides 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
!
CAUTION
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 must be:
• Correctly installed, if necessary, by a quali-
fied electrician.
• Correctly earthed (electrically) in accor-
dance with local regulations.
• Connected to the correct size power point
and fuse as per the Specifications on page
2-4.
WARNING
The Fabricator 141i must be electri-
cally connected by a qualified electri-
cal 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 electri-
cal parts.
SHUT DOWN welding Power Source, disconnect input power
employing lockout/tagging procedures. Lock-out/tagging pro-
cedures 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.
Electrical Input Requirements
Operate the welding Power Source from a single-phase 50/60
Hz, AC power supply. The input voltage must match one of the
electrical input voltages shown on the input data label on the
unit nameplate. Contact the local electric utility for informa-
tion about the type of electrical service available, how proper
connections should be made, and inspection required. The line
disconnect switch provides a safe and convenient means to
completely remove all electrical power from the welding power
