Manual 0-5226 1-1 SAFETY INSTRUCTIONS AND WARNINGS
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
work (ground) circuit.
12. Use only well-maintained equipment. Repair or
replace damaged parts at once.

* 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 FABRICATOR 211i
Manual 0-5226 1-3 SAFETY INSTRUCTIONS AND WARNINGS
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.
6. Do not weld in locations near degreasing, cleaning,
or spraying operations. The heat and rays of the
arc can react with vapours to form highly toxic
and irritating gases.
7. Do not weld on coated metals, such as galvanized,
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.
2. Do not weld where flying sparks can strike
flammable material.
3. Remove all flammables within 35 ft (10.7 m) 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 travelling 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.
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.
FABRICATOR 211i SAFETY INSTRUCTIONS
SAFETY INSTRUCTIONS AND WARNINGS 1-4 Manual 0-5226
5. Use only correct shielding gas cylinders,
regulators, hoses, and fittings designed for the
specific application; maintain them and associated
parts in good condition.
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.
WARNING
ENGINE FUEL can cause fire or explosion.
Engine fuel is highly flammable.
1. Stop engine before checking or adding fuel.
2. Do not add fuel while smoking or if unit is near
any sparks or open flames.
3. Allow engine to cool before fuelling. If possible,
check and add fuel to cold engine before beginning
job.
4. Do not overfill tank — allow room for fuel to
expand.
5. Do not spill fuel. If fuelling is spilled, clean up
before starting engine.
WARNING
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.
2. Stop engine before installing or connecting
unit.
3. Have only qualified people remove guards or
covers for maintenance and troubleshooting
as necessary.
4. To prevent accidental starting during servicing,
disconnect negative (-) battery cable from
battery.
5. Keep hands, hair, loose clothing, and tools
away from moving parts.
6. Reinstall panels or guards and close doors
when servicing is finished and before starting
engine.
WARNING
SPARKS can cause BATTERY GASES TO
EXPLODE; BATTERY ACID can burn eyes
and skin.
Batteries contain acid and generate explosive gases.
1. Always wear a face shield when working on a
battery.
2. Stop engine before disconnecting or connecting
battery cables.
3. Do not allow tools to cause sparks when working
on a battery.
4. Do not use welder to charge batteries or jump start
vehicles.
5. Observe correct polarity (+ and –) on batteries.
WARNING
STEAM AND PRESSURIZED HOT
COOLANT can burn face, eyes, and skin.
The coolant in the radiator can be very hot

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 minimize or avoid potential risks.”
To reduce magnetic fields in the workplace, use the
following procedures.
1. Keep cables close together by twisting or
taping them.
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.

1.05 EMF Information
Considerations About Welding And The Effects Of Low Frequency Electric And Magnetic Fields
Welding current, as it flows through welding cables, will cause electromagnetic fields. There has been and
still is some concern about such fields. However, after examining more than 500 studies spanning 17 years
of research, a special blue ribbon committee of the National Research Council concluded that: “The body of
evidence, in the committee’s judgment, has not demonstrated that exposure to power-frequency electric and
magnetic fields is a human-health hazard.” However, studies are still going forth and evidence continues to be
examined. Until the final conclusions of the research are reached, you may wish to minimize your exposure
to electromagnetic fields when welding or cutting.
To reduce magnetic fields in the workplace, use the following procedures:
1. Keep cables close together by twisting or taping them, or using a cable cover.
2. Arrange cables to one side and away from the operator.
3. Do not coil or drape cables around your body.
4. Keep welding power source and cables as far away from operator as practical.
5. Connect work clamp to workpiece as close to the weld as possible.
About Implanted Medical Devices:
Implanted Medical Device wearers should consult their doctor and the device manufacturer before performing or going near arc welding, spot welding, gouging, plasma arc cutting, or induction heating operations. If
cleared by your doctor, then following the above procedures is recommended.

3.01 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 20% duty cycle, 210 amperes at 24.5 volts. This means that it has been designed and built to provide the
rated amperage (210A) for 2 minutes, i.e. arc welding time, out of every 10 minute period (20% of 10 minutes is
2 minutes). During the other 8 minutes of the 10 minute period the Welding Power Source must idle and allowed
to cool. The thermal cut out will operate if the duty cycle is exceeded.

3.08 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.
NOTE
The welding circuit may or may not be
earthed for safety reasons. Changing the
earthing arrangements should only be authorized 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.
SAFETY/INSTALLATION FABRICATOR 211i
Manual 0-5226 3-5 SAFETY/INSTALLATION
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, signalling and
telephone cables; above, below and adjacent to the
welding equipment.
2. Radio and television transmitters and receivers.
3. Computer and other control equipment.
4. Safety critical equipment, e.g. guarding of industrial
equipment.
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
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.
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
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.

1. Power Indicator
The power indicator is illuminated when the correct mains power is applied to the power source and when the
ON/OFF switch located on the rear panel is in the ON position.
2. Thermal Overload Indicator (Fault Indicator)
This welding power source is protected by a self resetting thermostat. The indicator will illuminate if the duty
cycle of the power source has been exceeded. Should the thermal overload indicator illuminate the output
of the power source will be disabled. Once the power source cools down this light will go OFF and the over
temperature condition will automatically reset. Note that the mains power switch should remain in the on
position such that the fan continues to operate thus allowing the unit to cool sufficiently. Do not switch the
unit off should a thermal overload condition be present.
3. Digital Amps Meter (Left Digital Display)
MIG Mode
This digital meter is used to display the pre-set (preview) Wirefeed Speed in Meters Per Minute (MPM) in
MIG mode and actual welding amperage of the power source when welding. At times of non-welding, the
digital meter will display a pre-set (preview) value of Wirefeed Speed. This value can be adjusted by varying
the Amperage Control Knob (4).
STICK and LIFT TIG Modes
The digital meter is used to display the pre-set (preview) amperage in STICK / LIFT TIG modes and actual
welding amperage of the power source when welding. At times of non-welding, the amperage meter will
display a pre-set (preview) value in both STICK and LIFT TIG modes. This value can be adjusted by varying
the Amperage Control Knob (4).
SECTION 4:
OPERATION
FABRICATOR 211i OPERATION
OPERATION 4-2 Manual 0-5226
When welding, this digital meter will display actual welding amperage in all modes.
At the completion of welding, the digital meter will hold the last recorded amperage value for a period of
approximately 10 seconds in all modes. The amperage meter will hold the value until; (1) any of the front
panel controls are adjusted in which case the unit will revert to preview mode, (2) welding is recommenced,
in which case actual welding amperage will be displayed, or (3) a period of 10 seconds elapses following the
completion of welding in which case the unit will return to preview mode.
NOTE
The preview functionality provided on this power source is intended to act as a guide only. Some differences may be observed between preview values and actual welding values due to factors including
the mode of welding, differences in consumables/gas mixtures, individual welding techniques and the
transfer mode of the welding arc (ie dip versus spray transfer). Where exact settings are required (in
the case of procedural work), it is recommended that alternate measurement methods be utilized to
ensure output values are accurate.
4. Amperage Control (Wirespeed)
The amperage control knob adjusts the amount of welding current delivered by the power source. In STICK
(MMA) and LIFT TIG (GTAW) modes, the amperage control knob directly adjusts the power inverter to deliver
the desired level of output current. In MIG (GMAW/FCAW) 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 will 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.
NOTE
The preview functionality provided on this power source is intended to act as a guide only. Some differences may be observed between preview values and actual welding values due to factors including
the mode of welding, differences in consumables/gas mixtures, individual welding techniques and the
transfer mode of the welding arc (ie dip versus spray transfer). Where exact settings are required (in
the case of procedural work), it is recommended that alternate measurement methods be utilized to
ensure output values are accurate.
5. MIG Gun Adaptor (Euro Style)
The MIG gun adaptor is the connection point for the MIG welding gun. Connect the gun by pushing the gun
connector into the brass gun adaptor firmly and screwing the plastic nut clockwise to secure in position. To
remove the MIG gun simply reverse these directions.
6. Positive Welding Output Terminal
The positive welding terminal is used to connect the welding output of the power source to the appropriate
welding accessory such as the MIG gun (via the MIG polarity lead), electrode holder lead or work lead. Positive welding current flows from the power source via this heavy duty bayonet type terminal. It is essential,
however, that the male plug is inserted and turned securely to achieve a sound electrical connection.
CAUTION
Loose welding terminal connections can cause overheating and result in the male plug being fused in
the bayonet terminal.
7. MIG Polarity Lead
The polarity lead is used to connect the MIG gun to the appropriate positive or negative output terminal (allowing polarity reversal for different welding applications). In general, the polarity lead should be connected
in to the positive welding terminal (+) when using steel, stainless steel or aluminium electrode wire. When
using gasless wire, the polarity lead is generally connected to the negative welding terminal (-). If in doubt,
consult the manufacturer of the electrode wire for the correct polarity. It is essential, however, that the male
plug is inserted and turned securely to achieve a sound electrical connection.
