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, 100 amperes at 19 volts.
This means that it has been designed and built to provide the rated amperage (100 A) 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 be allowed to cool.

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 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 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
be operated or connected in a micro environment that
will exceed the stated conditions. For further information
please refer to EN 60529.

3.05 Electromagnetic Compatibility
WARNING
!
A. Installation and Use - Users Responsibility
The user is responsible for installing and using the weld-
ing 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.
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
2. Radio and television transmitters and receivers.
3. Computer and other control equipment.
4. Safety critical equipment, e.g. guarding of industrial
5. The health of people around, e.g. the use of pacemak-

7. The time of day that welding or other activities are to
Extra precautions for Electromagnetic
Compatibility may be required when
this Welding Power Source is used in a
domestic situation.
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. Further guidance
is given in EN 60974-13 Arc Welding

be carried out.
8. The compatibility 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. Electricity Supply
Welding equipment should be connected to the Elec-
tricity Supply according to the manufacturer’s recommendations. If interference occurs, it may be necessary to take additional precautions such as filtering of
the Electricity 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
it’s 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 main-
tained 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. In particular, the spark gaps of arc
striking and stabilizing devices should be adjusted
and maintained according to the manufacturer’s
recommendations.
3. Welding Cables
The welding cables should be kept as short as pos-
sible and should be positioned close together, 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 of the Workpiece
Where the workpiece is not bonded to earth for
electrical safety, nor connected to earth because of
it’s size and position, e.g. ship’s hull or building steelwork, a connection bonding the workpiece to earth
may reduce emissions in some, but not all instances.
Care should be taken to prevent the earthing of the
workpiece increasing the risk of injury to users, or
damage to other electrical equipment. Where necessary, the connection of the workpiece to earth should
Manual 0-5420 3-3 INSTALLATION, OPERATION AND SETUP
ESAB FABRICATOR 141i
A-09414_AC
be made by direct connection to the workpiece, 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 Electricity
Supply is applied to the Power Source and when the ON/
OFF switch located on the rear panel is in the ON position.
2. Digital Wirespeed/Amperage Meter (Left Digital Display)
This digital meter displays preview Wirespeed in MIG mode
only then actual amperage (weld current) once an arc has
been established. It also displays preview amperage in both
the STICK and LIFT TIG modes only then actual amperage
(weld current) once an arc has been established.
At times of non-welding, the amperage meter will display
a preview value in both STICK and LIFT TIG modes. This
value can be adjusted by varying the Wire speed / Amperage potentiometer (Control No. 3). At times of non-welding,
the amperage meter will preview a wirefeed speed value
(Inches Per Minute) in MIG mode only. This can be identified
as preview wirefeed speed by a decimal point at the lower
right hand side of the display.
When welding, the amperage meter will display actual
amperage (weld current) in all modes.
At the completion of welding, the amperage 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 Power Source 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 Power Source 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.
on the inside of the wire feed compartment door provides a
brief summary of the required settings for a basic range of
MIG (GMAW/FCAW) welding applications.
In STICK and LIFT TIG modes, the Wirespeed/Amperage
control knob adjusts the amount of amperage (weld current) delivered to the welding arc by the Power Source. It
directly adjusts the Power Source to deliver the desired level
of weld current.
4. MIG Gun Adapter (ESAB Style)
The MIG Gun adapter is standard ESAB connection with an
8 pin gun trigger for the Fusion MIG Gun. Connect the MIG
Gun by pushing the MIG Gun connector into the brass MIG
Gun Adapter firmly and screw the locking screw in the MIG
Gun Adapter within the Wire Feed Compartment to secure
the Fusion MIG Gun in position. Failure to properly lock the
Fusion MIG Gun into the MIG Gun Feedplate will result in the
MIG Gun being pushed out of the MIG Gun Feedplate by the
MIG welding wire or lack of shielding gas (porosity in the
weld) at the weld zone.
5. 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 Gun polarity
lead), electrode holder lead or work lead. Positive welding
current flows from the Power Source via 25mm Dinse style
connector. It is essential, however, that the Dinse adapter
and male plug are 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 Dinse connector.
6. MIG Gun 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
aluminum electrode wire. When using flux cored (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 Dinse adapter and male plug are inserted
and turned securely to achieve a sound electrical connection.
3. Wirespeed/Amperage Control
In MIG mode, the Wirespeed/Amperage control 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 depends upon the
material type and the welding application. The setup chart

7. 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 Gun polarity lead), TIG Torch or work lead. Negative welding current flows to the Power Source
via 25mm Dinse style connector. It is essential, however, that the Dinse adapter and male plug are inserted and turned securely
to achieve a sound electrical connection.
CAUTION
!
8. Remote Control and Spool Gun Socket
The 8 pin socket is used to connect the Fusion MIG Gun, remote control device or spool gun plug to the welding Power Source.
To make connections, align keyway, insert plug, and rotate threaded collar fully clockwise.
Loose welding terminal connections can cause overheating and result in the male plug being fused in the Dinse connector..

Note that the Local/ Remote Switch (Control No. 18) located in the wirefeed compartment should be set to Remote for remote
amperage/voltage controls to operate.
9. 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 utilized to ensure
output values are accurate.
INSTALLATION, OPERATION AND SETUP 3-8 Manual 0-5420
ESAB FABRICATOR 141i
When MIG Mode is Selected
In this mode the control knob is used to adjust the MIG
welding voltage of the Power Source. The welding voltage
is increased by turning the knob clockwise or decreased by
turning the knob counterclockwise. The optimum voltage
level required will depend 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 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 counterclockwise.
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 of the amperage 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 (Control No. 11), the
Power Source will enter down slope mode as soon as the
trigger switch is released (ie if the multifunction control knob
is set to 5, the Power Source will ramp down from the present
welding current to zero over 5 seconds). If no down slope
time is set then the welding output will cease immediately.
If the Power Source 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.
10. Arc Control (Inductance)
The arc control operates in MIG 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. Soft means maximum inductance
while Hard means minimum inductance.
11. Trigger Mode Control (MIG and LIFT TIG Mode only)
The trigger mode control is used to switch the functionality
of the of the MIG or TIG Trigger Switch between 2T (normal)
and 4T (latch mode)
2T (Normal Mode)
In this mode, the MIG or TIG Trigger Switch must remain
depressed for the welding output to be active. Press and
hold the MIG or TIG Trigger Switch to activate the Power
Source (weld). Release the MIG or TIG Trigger Switch to
cease welding.
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 MIG or TIG Trigger Switch and the
output will remain active. To deactivate the Power Source,
the trigger switch must again be depressed and released,
thus eliminating the need for the operator to hold the MIG
or TIG Trigger Switch
Note that when operating in LIFT TIG mode, the Power Source
will remain activated until the selected Downslope time has
elapsed (refer Control No. 9).
12. Process Selection Control
The process selection control is used to select the desired
welding mode. Three modes are available, MIG, LIFT TIG and
STICK modes. Refer to section 3.20 or 3.21 for MIG (GMAW/
FCAW) set up details, section 3.22 for LIFT TIG (GTAW) setup details or section 3.23 for STICK (SMAW) set-up details.
Note that when the Power Source 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 Power Source and mistakenly be in contact with the work piece during power up.
13. Digital Voltage Meter (Right Digital Display)
The digital voltage meter is used to display the both the
preview voltage (MIG mode only) and actual output voltage
(all modes) of the Power Source.
At times of non-welding, the voltage meter will display a
preview value in MIG mode. This value can be adjusted by
varying the multifunction control knob (Control No. 9). Note
that in STICK and LIFT TIG modes, the voltage meter will not
preview welding voltage but will display Open Circuit Voltage
in STICK mode and 0V in LIFT TIG mode.
When welding, the voltage meter will display actual
welding voltage in all modes.
At the completion of welding, the digital voltage 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 Power Source 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 Power Source 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.
14. 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 or if a fault is detected in the Inverter. Should the Fault 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
power switch should remain in the on position such that the
fan continues to operate thus allowing the Power Source to
cool sufficiently. Do not switch the Power Source off should
a thermal overload condition be present. If the fault condition
does not extinguish, then the Power Supply will need to be
taken to an authorized repair center for analysis.
15. Gas Inlet (MIG mode only for MIG Gun or Spool Gun
operation)
The Gas Inlet connection is used to supply the appropriate
MIG welding gas to the Power Source. Refer to section 3.19
to 3.20 for MIG (FCAW/GMAW) set up details.
WARNING
!
Only Welding Shielding Gases specifically
designed for arc welding applications
should be used.
16. On / Off Switch
This switch is used to turn the Power Source on/off.
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. Intelligent Fan Control
When Power Supply is first turned on it will default in MIG
Mode. The Fan will operate for approximately 10 seconds,
then shut down.
When triggered in MIG mode, fan will not turn on until Power
Supply reaches temperatures in which cooling is required.
When in Lift TIG mode, as soon as output is enabled, the
fan will come on immediately and will not shut down until
welding has ceased and Power Supply is at proper operating temperature. When set to Stick mode, fan will turn on
immediately and will not turn off until welding has ceased
and Power Supply is at proper operating temperature.
Note in STICK mode the fan operates continuously.
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 Power Source via the remote control socket
(8 Pin Remote Socket). When the local/remote switch is in
the remote position, the Power Source will detect a remote
device and work accordingly. When in the local mode, the
Power Source 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 Power
Source 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 counterclockwise. 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
The MIG Gun / Spool Gun switch is used to switch welding
mode between MIG Gun function and Spool Gun function.
21. 10A Fuse
The 10A fuse is used to protect both the spool gun motor
and internal motor.
