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.

* 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.
Page 10
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.
Page 23
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
Page 26
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.
Page 27
OPERATION FABRICATOR 211i
Manual 0-5226 4-3 OPERATION
CAUTION
Loose welding terminal connections can cause overheating and result in the male plug being fused in
the bayonet terminal.
8. Negative Welding Output Terminal
The negative 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), TIG torch or work lead. Negative welding
current flows to 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.

OPERATION 4-4 Manual 0-5226
10. Multifunction Control - Voltage, Down Slope & Arc Force
The multifunction control knob is used to adjust Voltage (MIG Mode), Down slope (LIFT TIG Mode) and Arc
Force (STICK Mode) depending on the welding mode selected.
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 utilised to
ensure output values are accurate.
When MIG (GMAW/FCAW) Mode is Selected
In this mode the control knob is used to adjust the output voltage of the unit. The welding voltage is increased
by turning the knob clockwise or decreased by turning the knob anti-clockwise. The optimum voltage level
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.
When STICK (MMA) Mode is Selected
In this mode the multifunction control knob is used to adjust arc force. Arc force control provides an adjustable amount of welding force (or “dig”) control. This feature 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 ‘10’ (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
anti-clockwise
When LIFT TIG Mode is Selected
In this mode the multifunction control knob is used to adjust down slope. Down slope allows the user to
select the ramp down time at the completion of the weld. The main function of down slope is to allow the
welding current to be gradually reduced over a pre-set time frame such that the welding pool is given time
to cool sufficiently.
Note that when in 2T normal mode (refer item 12), the unit will enter down slope mode as soon as the trigger
switch is released (ie if the multifunction control knob is set to 5, the unit will ramp down from the present
welding current to zero over 5 seconds). If no down slope time is selected then the welding output will cease
immediately. If the unit is set to 4T latch mode, to enter down slope mode the trigger must be held in for the
selected time period (ie press and release trigger to commence welding, then press and hold trigger again to
enter down slope mode). Should the trigger be released during the down slope phase (4T only), the output
will cease immediately.
11. Arc Control (Inductance)
The arc control operates in MIG (GMAW/FCAW) mode only and is used to adjust the intensity of the welding
arc. Lower arc control settings make the arc softer with less weld spatter. Higher arc control settings give a
stronger driving arc which can increase weld penetration.
12. Trigger Mode Control (MIG and LIFT TIG Mode only)
The trigger mode control is used to switch the functionality of the torch trigger between 2T (normal) and 4T
(latch mode)
2T Normal Mode
In this mode, the torch trigger must remain depressed for the welding output to be active. Press and hold the
torch trigger to activate the power source (weld). Release the torch trigger switch to cease welding.
Page 29
OPERATION FABRICATOR 211i
Manual 0-5226 4-5 OPERATION
4T Latch Mode
This mode of welding is mainly used for long welding runs to reduce operator fatigue. In this mode the operator can press and release the torch trigger and the output will remain active. To deactivate the power source,
the trigger switch must again be depressed and realised, thus eliminating the need for the operator to hold
the torch trigger.
Note that when operating in LIFT TIG (GTAW) mode, the power source will remain activated until the selected
downslope time has elapsed (refer Item 10).
13. Process Selection Control
The process selection control is used to select the desired welding mode. Three modes are available, MIG
(GMAW/FCAW), LIFT TIG (GTAW) and STICK (MMA) modes. Refer to section 4.10 or 4.11 for MIG (GMAW/
FCAW) set up details, section 4.12 for LIFT TIG (GTAW) set-up details or section 4.13 for STICK (MMA) setup details.
Note that when the unit is powered off the mode selection control will automatically default to MIG mode.
This is necessary so as to prevent inadvertent arcing should an electrode holder be connected to the unit and
mistakenly be in contact with the work piece during power up.
14. Digital Voltage Meter (Right Digital Display)
MIG Mode
This digital meter is used to display the pre-set (preview) Voltage in MIG mode and actual welding voltage
of the power source when welding. At times of non-welding, the digital meter will display a pre-set (preview)
value of Voltage. This value can be adjusted by varying the Multifunction Control Knob (10).
STICK and LIFT TIG Modes
This digital meter is used to display the Welding Output Terminal Voltage in STICK / LIFT TIG modes during
non-welding or welding. This value cannot be adjusted by varying the Multifunction Control Knob (10).
When welding, this digital meter will display actual welding voltage in all modes.
At the completion of welding, the digital meter will hold the last recorded voltage value for a period of approximately 10 seconds in all modes. The voltage 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.
15. Gas Inlet (MIG mode only)
The Gas Inlet connection is used to supply the appropriate MIG welding gas to the unit. Refer to section 4.10
set up details.
!
WARNING
Only Inert Shielding Gases specifically designed for welding applications should be used.

16. On / Off Switch
This Single Phase circuit breaker performs a dual function.
It is used to turn the unit on/off and it will also trip in the event of a fault.
WARNING
When the front digital displays are lit, the machine is connected to the Mains supply voltage and the
internal electrical components are at Mains voltage potential.

17. Wiredrive Motor Circuit Breaker
The 4A Circuit Breaker protects the unit from electrical faults and will operate in the event of a motor overload.
NOTE
If a circuit breaker trips, a short cooling period must be allowed before an attempt is made to reset the
unit by pressing the circuit breaker reset button
.
18. Local / Remote Switch (located in wirefeed compartment)
The local/ remote switch is used only when a remote control device (such as a TIG torch with remote current
control) is fitted to the unit via the remote control socket (item 9). When the local/ remote switch is in the
remote position, the unit will detect a remote device and work accordingly. When in the local mode, the unit
will not detect the remote device and will operate from the power source controls only. Note that the trigger
will operate at all times on the remote control socket irrespective of the position of the local/ remote switch
(ie in both local and remote modes).
Should a remote device be connected and the local/ remote switch set to remote, the maximum setting of
the power source will be determined by the respective front panel control, irrespective of the remote control
device setting. As an example, if the output current on the power source front panel is set to 50% and the
remote control device is set to 100%, the maximum achievable output from the unit will be 50%. Should 100%
output be required, the respective front panel control must be set to 100%, in which case the remote device
will then be able to control between 0-100% output.

19. Burnback Control (located in wirefeed compartment)
The burnback control is used to adjust the amount of MIG wire that protrudes from the MIG gun after the
completion of MIG welding (commonly referred to as stick out). To decrease the burnback time (or lengthen
the amount of wire protruding from the MIG gun at the completing of welding), turn the burnback control
knob anti clockwise. To increase the burnback time (or shorten the amount of wire protruding from the MIG
gun at the completing of welding), turn the Burnback Control knob clockwise.
20. MIG Gun/ SPOOL Gun Switch (located in wirefeed compartment)
The MIG Gun / SPOOL Gun switch is used to switch welding mode between MIG Gun functionality and SPOOL
Gun functionality.
21. Cooling Fan
The Fabricator 211i is fitted with a fan as needed feature. Fan as needed automatically switches the cooling
fan off when it is not required. This has two main advantages; (1) to minimize power consumption, and (2) to
minimise the amount of contaminants such as dust that are drawn into the power source.
Note that the fan will only operate when required for cooling purposes and will automatically switch off when
not required.
4.02 Attaching MIG Gun
Fit the MIG gun to the power source by pushing the MIG gun connector into the MIG gun adaptor and screwing
the plastic nut clockwise to secure the MIG gun to the MIG gun adaptor.

4.06 Feed Roller Pressure Adjustment
The pressure (top) roller applies pressure to the grooved feed roller via an adjustable pressure screw. These
devices should be adjusted to a minimum pressure that will provide satisfactory WIREFEED without slippage. If
slipping occurs, and inspection of the wire contact tip reveals no wear, distortion or burn back jam, the conduit
liner should be checked for kinks and clogging by metal flakes and swarf. If it is not the cause of slipping, the feed
roll pressure can be increased by rotating the pressure screw clockwise.
WARNING
Before changing the feed roller ensure that the mains supply to the power source is switched off.
CAUTION
The use of excessive pressure may cause rapid wear of the feed rollers, shafts and bearing.
4.07 Changing the Feed Roll
To change feed roll remove the feed roll retaining screw by turning in an anticlockwise direction. Once the feed
roll is removed then to replace feed roll simply reverse these directions.
A dual groove feed roller is supplied as standard. It can accommodate 0.6/0.8mm diameter hard wires. Select the
roller required with the chosen wire size marking facing outward.

5.14 Main Circuit Description
!
Turn off power and disconnect mains supply plug from receptacle before working on the unit. Allow two minutes
for capacitors to discharge after disconnection from mains supply voltage.
The mains supply voltage is connected via a double pole switch to the input rectifier Q1 through an EMC filter. Overvoltage protection is provided by varistor CY1.
The rectifier output charges the main capacitor bank (C16, C17, C18, C19, C22 and C23) to high voltage. Inrush current
limiting is provided by a PTC which is then bypassed by relay J1 after a few seconds.
The primary igbt transistors (T1, T2, T4, and T5) switch the transformer primary at high frequency and varying duty
cycle. The transformer return wire is taken from the junction of the capacitors C20 and C21 (the voltage at this point is
approximately half the DC bus voltage).
Secondary output voltage from the transformer is rectified by the output diodes (T13, T14, T15, T16, T17, T18, T19, and
T20) to DC. This DC is controlled by the PWM of the primary side igbt transistors, and is filtered by an inductor before
connecting to the welding output terminals.
A thermal overload device (thermistor) is fixed to the rectifier heatsink. When an over temperature occurs, the control
circuit inhibits the trigger, gas solenoid, wire drive system and the welding output. The thermal overload indicator LED
on the front panel is illuminated.
The current transformer TR8 provides a signal to the control circuit to indicate both transformer primary current, and also
detect transformer saturation. The Hall effect current sensor is powered from regulated + & - 15VDC supplies and provides
a voltage signal proportional to the output DC welding current to allow the control circuit to regulate welding current.
