1.01 Arc Welding Hazards
WARNING
ELECTRIC SHOCK can kill.
Touching live electrical parts can cause
fatal shocks or severe burns. The electrode
and work circuit is electrically live whenever the output is on. The input power circuit and machine internal circuits are also
live when power is on. In semi-automatic
or automatic wire welding, the wire, wire
reel, drive roll housing, and all metal parts
touching the welding wire are electrically
live. Incorrectly installed or improperly
grounded equipment is a hazard.
1. Do not touch live electrical parts.
2. Wear dry, hole-free insulating gloves and body
protection.
3. Insulate yourself from work and ground using dry
insulating mats or covers.
4. Disconnect input power or stop engine before
installing or servicing this equipment. Lock input
power disconnect switch open, or remove line
fuses so power cannot be turned on accidentally.
5. Properly install and ground this equipment
according to its Owner’s Manual and national,
state, and local codes.
6. Turn OFF all equipment when not in use.
Disconnect power to equipment if it will be left
unattended or out of service.
7. Use fully insulated electrode holders. Never dip
holder in water to cool it or lay it down on the
ground or the work surface. Do not touch holders
connected to two welding machines at the same
time or touch other people with the holder or
electrode.
8. Do not use worn, damaged, undersized, or poorly
spliced cables.
9. Do not wrap cables around your body.
10. Ground the workpiece to a good electrical (earth)
ground.
11. Do not touch electrode while in contact with the

* As a rule of thumb, start with a shade that is too dark to see the weld zone. Then go to a lighter
shade which gives sufficient view of the weld zone without going below the minimum. In oxyfuel gas
welding, cutting, or brazing where the torch and/or the flux produces a high yellow light, it is desirable
to use a filter lens that absorbs the yellow or sodium line of the visible light spectrum.

SAFETY INSTRUCTIONS AND WARNINGS 1-2 Manual 0-5193
SAFETY INSTRUCTIONS FABRICATOR 252i
2. Do not weld where flying sparks can strike
flammable material.
WARNING
FUMES AND GASES can be hazardous to
your health.
Welding produces fumes and gases.
Breathing these fumes and gases can be
hazardous to your health.
1. Keep your head out of the fumes. Do not breathe
the fumes.
2. If inside, ventilate the area and/or use exhaust at
the arc to remove welding fumes and gases.
3. If ventilation is poor, use an approved air-supplied
respirator.
4. Read the Material Safety Data Sheets (MSDSs)
and the manufacturer’s instruction for metals,
consumables, coatings, and cleaners.
5. Work in a confined space only if it is well ventilated,
or while wearing an air-supplied respirator.
Shielding gases used for welding can displace air
causing injury or death. Be sure the breathing air
is safe.
3. Remove all flammables within 10.7 m (35 ft) of the
welding arc. If this is not possible, tightly cover
them with approved covers.
4. Be alert that welding sparks and hot materials from
welding can easily go through small cracks and
openings to adjacent areas.
5. Watch for fire, and keep a fire extinguisher nearby.
6. Be aware that welding on a ceiling, floor, bulkhead,
or partition can cause fire on the hidden side.
7. Do not weld on closed containers such as tanks
or drums.
8. Connect work cable to the work as close to the
welding area as practical to prevent welding
current from traveling long, possibly unknown
paths and causing electric shock and fire hazards.
9. Do not use welder to thaw frozen pipes.
10. Remove stick electrode from holder or cut off
welding wire at contact tip when not in use.
6. Do not weld in locations near degreasing, cleaning,
or spraying operations. The heat and rays of the
arc can react with vapors to form highly toxic and
irritating gases.
7. Do not weld on coated metals, such as galvanised,
lead, or cadmium plated steel, unless the coating
is removed from the weld area, the area is well
ventilated, and if necessary, while wearing an airsupplied respirator. The coatings and any metals
containing these elements can give off toxic fumes
if welded.
WARNING
WELDING can cause fire or explosion.
Sparks and spatter fly off from the
welding arc. The flying sparks and hot
metal, weld spatter, hot workpiece, and
hot equipment can cause fires and burns.
Accidental contact of electrode or welding
wire to metal objects can cause sparks,
overheating, or fire.
1. Protect yourself and others from flying sparks and
hot metal.
WARNING
FLYING SPARKS AND HOT METAL can
cause injury.
Chipping and grinding cause flying metal.
As welds cool, they can throw off slag.
1. Wear approved face shield or safety goggles. Side
shields recommended.
2. Wear proper body protection to protect skin.
WARNING
CYLINDERS can explode if damaged.
Shielding gas cylinders contain gas under
high pressure. If damaged, a cylinder can
explode. Since gas cylinders are normally
part of the welding process, be sure to
treat them carefully.
1. Protect compressed gas cylinders from excessive
heat, mechanical shocks, and arcs.
2. Install and secure cylinders in an upright position
by chaining them to a stationary support or
equipment cylinder rack to prevent falling or
tipping.

3. Keep cylinders away from any welding or other
electrical circuits.
4. Never allow a welding electrode to touch any
cylinder.
5. Use only correct shielding gas cylinders,
regulators, hoses, and fittings designed for the
specific application; maintain them and associated
parts in good condition.
MOVING PARTS can cause injury.
Moving parts, such as fans, rotors, and belts can cut
fingers and hands and catch loose clothing.
1. Keep all doors, panels, covers, and guards
closed and securely in place.
WARNING
6. Turn face away from valve outlet when opening
cylinder valve.
7. Keep protective cap in place over valve except
when cylinder is in use or connected for use.
8. Read and follow instructions on compressed
gas cylinders, associated equipment, and CGA
publication P-1 listed in Safety Standards.
WARNING
Engines can be dangerous.
WARNING
ENGINE EXHAUST GASES can kill.
Engines produce harmful exhaust gases.
1. Use equipment outside in open, well-ventilated
areas.
2. If used in a closed area, vent engine exhaust
outside and away from any building air intakes.
2. Stop engine before installing or connecting
unit.

NOTE
Considerations About Welding And The
Effects of Low Frequency Electric and
Magnetic Fields
The following is a quotation from the General Conclusions Section of the U.S. Congress, Office of
Technology Assessment, Biological Effects of Power
Frequency Electric & Magnetic Fields - Background
Paper, OTA-BP-E-63 (Washington, DC: U.S. Government Printing Office, May 1989): “...there is now
a very large volume of scientific findings based on
experiments at the cellular level and from studies with
animals and people which clearly establish that low
frequency magnetic fields interact with, and produce
changes in, biological systems. While most of this
work is of very high quality, the results are complex.
Current scientific understanding does not yet allow us
to interpret the evidence in a single coherent framework. Even more frustrating, it does not yet allow
us to draw definite conclusions about questions of
possible risk or to offer clear science-based advice
on strategies to minimise or avoid potential risks.”
To reduce magnetic fields in the workplace, use the
following procedures.
2. Arrange cables to one side and away from the
operator.
3. Do not coil or drape cable around the body.
4. Keep welding Power Source and cables as far
away from body as practical.
ABOUT PACEMAKERS:
The above procedures are among
those also normally recommended for
pacemaker wearers. Consult your doctor
for complete information.
1.02 General Safety Information for Victor CS Regulator
A. Fire Prevention
Welding and cutting operations use fire or combustion as a basic tool. The process is very useful when
properly controlled. However, it can be extremely
destructive if not performed cor rectly in the proper
environment.
1. The work area must have a fireproof floor.
2. Work benches or tables used during welding
or cutting operations must have fireproof
tops.
3. Use heat resistant shields or other approved
material to protect nearby walls or unprotected
flooring from sparks and hot metal.
4. Keep an approved fire extinguisher of the
proper size and type in the work area. Inspect
it regularly to ensure that it is in proper working order. Know how to use the fire extinguisher.
5. Move combustible materials away from the
work site. If you can not move them, protect
them with fireproof covers.

WARNING
Practice the following safety and operation
precautions EVERY TIME you use pressure
regulation equipment. Deviation from the
following safety and operation instructions
can result in fire, explosion, damage to
equipment, or injury to the operator.
WARNING
NEVER allow oxygen to contact grease, oil,
or other flam mable substances. Although
oxygen by itself will not burn, these substances become highly explosive. They
can ignite and burn violently in the presence of oxygen.
Keep ALL apparatus clean and free of grease, oil and
other flammable substances.
C. Ventilation
WARNING
Ade quately ventilate welding, heating, and
cutting work areas to prevent accumulation of explosive or toxic concen trations
of gases. Certain combinations of metals,
coatings, and gases generate toxic fumes.
Use respiratory protection equipment
in these circumstances. When welding/
brazing, read and understand the Material Safety Data Sheet for the welding/
brazing alloy.
D. Personal Protection
Gas flames produce infrared radiation which may
have a harm ful effect on the skin and especially on the
eyes. Select goggles or a mask with tempered lenses,
shaded 4 or darker, to protect your eyes from injury
and provide good visibility of the work.
E. Compressed Gas Cylinders
The Department of Transportation (DOT) approves
the design and manufacture of cylinders that contain
gases used for welding or cutting operations.
1. Place the cylinder (Figure 1-1) where you will
use it. Keep the cylinder in a vertical position.
Secure it to a cart, wall, work bench, post, etc.
Art # A-12127
Figure 1-1: Gas Cylinders
WARNING
Cylinders are highly pressurised. Handle
with care. Serious accidents can result
from improper handling or mis use of
compressed gas cylinders DO NOT drop
the cylinder, knock it over, or expose it to
excessive heat, flames or sparks. DO NOT
strike it against other cylinders. Contact
your gas supplier or refer to CGA P-1
“Safe Handling of Compressed Gases in
Containers” publication.
NOTE
Always wear protective gloves and flame-resistant clothing to protect skin and clothing from sparks and slag.

2. Place the valve protection cap on the cylinder
whenever mov ing it, placing it in storage, or
not using it. Never drag or roll cylinders in
any way. Use a suitable hand truck to move
cylin ders.
3. Store empty cylinders away from full cylinders. Mark them “EMPTY” and close the
cylinder valve.
4. NEVER use compressed gas cylinders without
a pressure reducing regulator attached to the
cylinder valve.
5. Inspect the cylinder valve for oil, grease, and
damaged parts.
WARNING
DO NOT use the cylinder if you find oil,
grease or damaged parts. Inform your
gas supplier of this condition immediately.
6. Momentarily open and close (called “cracking”)
the cylinder valve to dislodge any dust or dirt
that may be present in the valve.
CAUTION
Open the cylinder valve slightly. If you
open the valve too much, the cylinder
could tip over. When cracking the cylinder
valve, DO NOT stand directly in front of the
cylinder valve. Always perform cracking
in a well ventilated area. If an acetylene
cylinder sprays a mist when cracked, let
it stand for 15 minutes. Then, try to crack
the cylinder valve again. If this problem
persists, contact your gas supplier.

2.09 Duty Cycle
The rated duty cycle of a Welding Power Source is a statement of the time it may be operated at its rated welding current output without exceeding the temperature limits of the insulation of the component parts. To explain
the 10 minute duty cycle period the following example is used. Suppose a Welding Power Source is designed to
operate at a 40% duty cycle, 250 amperes at 26.5 volts. This means that it has been designed and built to provide
the rated amperage (250A) for 4 minutes, i.e. arc welding time, out of every 10 minute period (40% of 10 minutes
is 4 minutes). During the other 6 minutes of the 10 minute period the Welding Power Source must idle and be
allowed to cool.

SECTION 3: INSTALLATION OPERATION AND SETUP
3.01 Environment
This unit is designed for use in environments with
increased hazard of electric shock. 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.
G. The enclosure design of this power source meets
the requirements of IP23S as outlined in EN 60529
/ IEC 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.
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 (32° F
to 104° F.)
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 1 foot or more from walls or
similar that could restrict natural air flow for cooling.
3.04 Mains Supply Voltage Requirements
The Mains supply voltage
should be within ± 15% of the rated Mains supply voltage. 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

3.05 Electromagnetic Compatibility
WARNING
Extra precautions for Electromagnetic Compatibility may be required when this Welding Power Source
is used in a domestic situation.
A. Installation and Use - Users Responsibility
The user is responsible for installing and using the welding equipment according to the manufacturer’s instructions.
If electromagnetic disturbances are detected then it shall be the responsibility of the user of the welding equipment
to resolve the situation with the technical assistance of the manufacturer. In some cases this remedial action may
be as simple as earthing the welding circuit, see NOTE below. In other cases it could involve constructing an
electromagnetic screen enclosing the Welding Power Source and the work, complete with associated input filters.
In all cases, electromagnetic disturbances shall be reduced to the point where they are no longer Troublesome.
INSTALLATION/SETUP 3-2 Manual 0-5193
INSTALLATION/SETUP FABRICATOR 252i
NOTE
The welding circuit may or may not be
earthed for safety reasons. Changing the
earthing arrangements should only be authorised by a person who is competent to
assess whether the changes will increase the
risk of injury, e.g. by allowing parallel welding current return paths which may damage the earth circuits of other equipment.
Further guidance is given in EN 60974-13 /
IEC 60974-13.
B. Assessment of Area
Before installing welding equipment, the user shall make
an assessment of potential electromagnetic problems
in the surrounding area. The following shall be taken
into account.
1. Other supply cables, control cables, signaling and
telephone cables; above, below and adjacent to the
welding equipment.
electrically continuous throughout its length. The
shielding should be connected to the Welding Power
Source so that good electrical contact is maintained
between the conduit and the Welding Power Source
enclosure.
2. Maintenance of Welding Equipment
The welding equipment should be routinely
maintained according to the manufacturer’s
recommendations. All access and service doors and
covers should be closed and properly fastened when
the welding equipment is in operation. The welding
equipment should not be modified in any way except
for those changes and adjustments covered in the
manufacturer’s instructions.
3. Welding Cables
The welding cables should be kept as short as
possible and should be positioned close together
but never coiled and running at or close to the floor
level.
2. Radio and television transmitters and receivers.
3. Computer and other control equipment.
4. Safety critical equipment, e.g. guarding of industrial
equipment.
4. Equipotential Bonding
Bonding of all metallic components in the welding
installation and adjacent to it should be considered.
However, metallic components bonded to the work
piece will increase the risk that the operator could
5. The health of people around, e.g. the use of pacemakers and hearing aids.
6. Equipment used for calibration and measurement.
7. The time of day that welding or other activities are
to be carried out.
8. The immunity of other equipment in the environment:
the user shall ensure that other equipment being
used in the environment is compatible: this may
require additional protection measures.
The size of the surrounding area to be considered
will depend on the structure of the building and other
activities that are taking place. The surrounding area
may extend beyond the boundaries of the premises.
C. Methods of Reducing Electromagnetic Emissions
1. Mains Supply
Welding equipment should be connected to the
mains supply according to the manufacturer’s
recommendations. If interference occurs, it may
be necessary to take additional precautions such
as filtering of the mains supply. Consideration
should be given to shielding the supply cable
of permanently installed welding equipment in
metallic conduit or equivalent. Shielding should be
Manual 0-5193 3-3 INSTALLATION/SETUP
receive a shock by touching the metallic components
and the electrode at the same time. The operator
should be insulated from all such bonded metallic
components.
5. Earthing/grounding of the Work Piece
Where the work piece is not bonded to earth for
electrical safety, nor connected to earth because
of its size and position, e.g. ship’s hull or building
steelwork, a connection bonding the work piece to
earth may reduce emissions in some, but not all
instances. Care should be taken to prevent the earthing of the work piece increasing the risk of injury
to users, or damage to other electrical equipment.
Where necessary, the connection of the work piece
to earth should be made by direct connection to
the work piece, but in some countries where direct
connection is not permitted, the bonding should be
achieved by suitable capacitance, selected according
to national regulations.
6. Screening and Shielding
Selective screening and shielding of other cables
and equipment in the surrounding area may alleviate
problems of interference. Screening the entire
welding installation may be considered for special
applications.

WIRESPEED
The amperage control knob adjusts the amount of welding current delivered by the power source. In STICK and
LIFT TIG modes, the amperage control knob directly
adjusts the power inverter to deliver the desired level
of output current. In MIG mode, the amperage knob
adjusts the speed of the wire feed motor (which in turn
adjusts the output current by varying the amount of
MIG wire delivered to the welding arc). The optimum
wire speed required is dependent on the type of welding
application. The setup chart on the inside of the wire
feed compartment door provides a brief summary of
the required output settings for a basic range of MIG
welding applications. The value may also be adjusted
while a weld is in progress – if this occurs, the left
display will briefly switch to show the adjusted value
as the knob is turned, and will automatically revert back

can be particularly beneficial in providing the operator
the ability to compensate for variability in joint fit-up in
certain situations with particular electrodes. In general
increasing the arc force control toward ‘100%’ (maximum arc force) allows greater penetration control to be
achieved. Arc force is increased by turning the control
knob clockwise or decreased by turning the knob anticlockwise. This feature can be accessed and adjusted
during welding.
