BE SURE THAT ALL INSTALLATION, OPERATION,
MAINTENANCE AND REPAIR PROCEDURES ARE
PERFORMED ONLY BY QUALIFIED INDIVIDUALS.
1.d. Keep all equipment safety guards, covers
and devices in position and in good repair.
Keep hands, hair, clothing and tools away
from V-belts, gears, fans and all other
moving parts when starting, operating or
repairing equipment.
1.e. In some cases it may be necessary to remove safety guards to
perform required maintenance. Remove guards only when
necessary and replace them when the maintenance requiring
their removal is complete. Always use the greatest care when
working near moving parts.
1.f. Do not put your hands near the engine fan. Do not attempt to
override the governor or idler by pushing on the throttle control
rods while the engine is running.
1.g. To prevent accidentally starting gasoline engines while turning
the engine or welding generator during maintenance work,
disconnect the spark plug wires, distributor cap or magneto wire
as appropriate.
1.h. To avoid scalding, do not remove the radiator
pressure cap when the engine is hot.
ELECTRIC AND
MAGNETIC FIELDS MAY
BE DANGEROUS
2.a. Electric current flowing through any conductor
causes localized Electric and Magnetic Fields (EMF).
Welding current creates EMF fields around welding cables
and welding machines
2.b. EMF fields may interfere with some pacemakers, and
welders having a pacemaker should consult their physician
before welding.
FOR ENGINE POWERED
EQUIPMENT.
1.a. Turn the engine off before troubleshooting
and maintenance work unless the
maintenance work requires it to be running.
1.b. Operate engines in open, well-ventilated
areas or vent the engine exhaust fumes outdoors.
1.c. Do not add the fuel near an open flame
welding arc or when the engine is running.
Stop the engine and allow it to cool before
refueling to prevent spilled fuel from
vaporizing on contact with hot engine parts
and igniting. Do not spill fuel when filling
tank. If fuel is spilled, wipe it up and do not start engine until
fumes have been eliminated.
2.c. Exposure to EMF fields in welding may have other health effects
which are now not known.
2.d. All welders should use the following procedures in order to
minimize exposure to EMF fields from the welding circuit:
2.d.1. Route the electrode and work cables together - Secure
them with tape when possible.
2.d.2. Never coil the electrode lead around your body.
2.d.3. Do not place your body between the electrode and work
cables. If the electrode cable is on your right side, the
work cable should also be on your right side.
2.d.4. Connect the work cable to the workpiece as close as possible to the area being welded.
2.d.5. Do not work next to welding power source.
Safety 02 of 04 - 06/15/2016
SAFETY
ELECTRIC SHOCK
CAN KILL.
ARC RAYS CAN BURN.
3.a. The electrode and work (or ground) circuits are
electrically “hot” when the welder is on. Do
not touch these “hot” parts with your bare skin or wet clothing.
Wear dry, hole-free gloves to insulate hands.
4.a.
Use a shield with the proper filter and cover plates to protect your
eyes from sparks and the rays of the arc when welding or
observing open arc welding. Headshield and filter lens should
conform to ANSI Z87. I standards.
3.b. Insulate yourself from work and ground using dry insulation.
Make certain the insulation is large enough to cover your full area
of physical contact with work and ground.
4.b.
Use suitable clothing made from durable flame-resistant material
to protect your skin and that of your helpers from the arc rays.
4.c.
Protect other nearby personnel with suitable, non-flammable
screening and/or warn them not to watch the arc nor expose
themselves to the arc rays or to hot spatter or metal.
In addition to the normal safety precautions, if
welding must be performed under electrically
hazardous conditions (in damp locations or while
wearing wet clothing; on metal structures such as
floors, gratings or scaffolds; when in cramped
positions such as sitting, kneeling or lying, if there
is a high risk of unavoidable or accidental contact
with the workpiece or ground) use the following
equipment:
• Semiautomatic DC Constant Voltage (Wire) Welder.
• DC Manual (Stick) Welder.
• AC Welder with Reduced Voltage Control.
3.c. In semiautomatic or automatic wire welding, the electrode,
electrode reel, welding head, nozzle or semiautomatic welding
gun are also electrically “hot”.
3.d. Always be sure the work cable makes a good electrical
connection with the metal being welded. The connection should
be as close as possible to the area being welded.
3.e. Ground the work or metal to be welded to a good electrical (earth)
ground.
3.f. Maintain the electrode holder, work clamp, welding cable and
welding machine in good, safe operating condition. Replace
damaged insulation.
3.g. Never dip the electrode in water for cooling.
3.h. Never simultaneously touch electrically “hot” parts of electrode
holders connected to two welders because voltage between the
two can be the total of the open circuit voltage of both
welders.
FUMES AND GASES
CAN BE DANGEROUS.
5.a. Welding may produce fumes and gases
hazardous to health. Avoid breathing these fumes and gases.
When welding, keep your head out of the fume. Use enough
ventilation and/or exhaust at the arc to keep fumes and gases
away from the breathing zone. When welding hardfacing
(see instructions on container or SDS) or on lead
or cadmium plated steel and other metals or
coatings which produce highly toxic fumes, keep
exposure as low as possible and within applicable
OSHA PEL and ACGIH TLV limits using local
exhaust or mechanical ventilation unless exposure
assessments indicate otherwise. In confined
spaces or in some circumstances, outdoors, a
respirator may also be required. Additional
precautions are also required when welding
on galvanized steel.
5. b. The operation of welding fume control equipment is affected by
various factors including proper use and positioning of the
equipment, maintenance of the equipment and the specific
welding procedure and application involved. Worker exposure
level should be checked upon installation and periodically
thereafter to be certain it is within applicable OSHA PEL and
ACGIH TLV limits.
3.i. When working above floor level, use a safety belt to protect
yourself from a fall should you get a shock.
5.c. Do not weld in locations near chlorinated hydrocarbon vapors
coming from degreasing, cleaning or spraying operations. The
heat and rays of the arc can react with solvent vapors to form
phosgene, a highly toxic gas, and other irritating products.
3.j. Also see Items 6.c. and 8.
5.d. Shielding gases used for arc welding can displace air and cause
injury or death. Always use enough ventilation, especially in
confined areas, to insure breathing air is safe.
5.e. Read and understand the manufacturer’s instructions for this
equipment and the consumables to be used, including the
Safety Data Sheet (SDS) and follow your employer’s safety
practices. SDS forms are available from your welding
distributor or from the manufacturer.
5.f. Also see item 1.b.
Safety 03 of 04 - 06/15/2016
SAFETY
WELDING AND CUTTING
SPARKS CAN CAUSE
FIRE OR EXPLOSION.
6.a. Remove fire hazards from the welding area. If
this is not possible, cover them to prevent the welding sparks
from starting a fire. Remember that welding sparks and hot
materials from welding can easily go through small cracks and
openings to adjacent areas. Avoid welding near hydraulic lines.
Have a fire extinguisher readily available.
6.b. Where compressed gases are to be used at the job site, special
precautions should be used to prevent hazardous situations.
Refer to “Safety in Welding and Cutting” (ANSI Standard Z49.1)
and the operating information for the equipment being used.
6.c. When not welding, make certain no part of the electrode circuit is
touching the work or ground. Accidental contact can cause
overheating and create a fire hazard.
6.d. Do not heat, cut or weld tanks, drums or containers until the
proper steps have been taken to insure that such procedures
will not cause flammable or toxic vapors from substances inside.
They can cause an explosion even though they have been
“cleaned”. For information, purchase “Recommended Safe
Practices for the Preparation for Welding and Cutting of
Containers and Piping That Have Held Hazardous Substances”,
AWS F4.1 from the American Welding Society
(see address above).
6.e. Vent hollow castings or containers before heating, cutting or
welding. They may explode.
6.f. Sparks and spatter are thrown from the welding arc. Wear oil free
protective garments such as leather gloves, heavy shirt, cuffless
trousers, high shoes and a cap over your hair. Wear ear plugs
when welding out of position or in confined places. Always wear
safety glasses with side shields when in a welding area.
6.g. Connect the work cable to the work as close to the welding area
as practical. Work cables connected to the building framework or
other locations away from the welding area increase the
possibility of the welding current passing through lifting chains,
crane cables or other alternate circuits. This can create fire
hazards or overheat lifting chains or cables until they fail.
6.h. Also see item 1.c.
6.I. Read and follow NFPA 51B “Standard for Fire Prevention During
Welding, Cutting and Other Hot Work”, available from NFPA, 1
Batterymarch Park, PO box 9101, Quincy, MA 022690-9101.
6.j. Do not use a welding power source for pipe thawing.
CYLINDER MAY EXPLODE IF
DAMAGED.
7.a. Use only compressed gas cylinders containing
the correct shielding gas for the process used
and properly operating regulators designed for
the gas and pressure used. All hoses, fittings,
etc. should be suitable for the application and
maintained in good condition.
7.b. Always keep cylinders in an upright position securely chained to
an undercarriage or fixed support.
7.c. Cylinders should be located:
•
Away from areas where they may be struck or subjected
to physical damage.
•
A safe distance from arc welding or cutting operations
and any other source of heat, sparks, or flame.
7.d. Never allow the electrode, electrode holder or any other
electrically “hot” parts to touch a cylinder.
7.e. Keep your head and face away from the cylinder valve outlet
when opening the cylinder valve.
7.f. Valve protection caps should always be in place and hand tight
except when the cylinder is in use or connected for use.
7.g. Read and follow the instructions on compressed gas cylinders,
associated equipment, and CGA publication P-l, “Precautions for
Safe Handling of Compressed Gases in Cylinders,” available from
the Compressed Gas Association, 14501 George Carter Way
Chantilly, VA 20151.
FOR ELECTRICALLY
POWERED EQUIPMENT.
8.a. Turn off input power using the disconnect
switch at the fuse box before working on
the equipment.
8.b. Install equipment in accordance with the U.S. National Electrical
Code, all local codes and the manufacturer’s recommendations.
8.c. Ground the equipment in accordance with the U.S. National
Electrical Code and the manufacturer’s recommendations.

(EARTH) GROUND.
----------------------------------------------------------------------
CAUTION
VRD™ (VOLTAGE REDUCTION DEVICE)
The VRD™ feature provides additional safety in the Stick
mode. The VRD™ reduces the OCV (Open Circuit Voltage)
at the welding output terminals while not welding to less
than 35VDC peak.
The VRD™ requires that the welding cable connections be
kept in good electrical condition because poor connections
will contribute to poor starting. Having good electrical connections also limits the possibility of other safety issues
such as heat-generated damage, burns and fires.
The machine is shipped with VRD™ “Disabled”. The VRD™
function can be disabled or enabled via dip switches on the
control P.C. board. Dip switch setting will differ depending
on input voltage.
The control board and dip switches can be accessed by
removing the case top and side as shown in the Operation
Section figure B.3.
SELECT SUITABLE LOCATION
LOCATION AND VENTILATION FOR COOLING
Place the welder where clean cooling air can freely
circulate in through the rear louvers and out through
the case sides. Dirt, dust, or any foreign material that
can be drawn into the welder should be kept at a minimum. Failure to observe these precautions can result
in excessive operating temperatures and nuisance
shutdowns.
TILTING
Place the machine directly on a secure, level surface
or on a recommended undercarriage. The machine
may topple over if this procedure is not followed.
Do not mount the FX650 over combustible surfaces. Where there is a combustible surface
directly under stationary or fixed electrical equipment, that surface shall be covered with a steel
plate at least .060” (1.6mm) thick, which shall
extend not less than 5.90” (150mm) beyond the
equipment on all sides.
-----------------------------------------------------------------------
INPUT AND GROUNDING CONNECTIONS
MACHINE GROUNDING
The frame of the welder must be grounded.
A ground terminal marked with the symbol
shown is located inside the reconnect/input connection area for this purpose. See your local and national
electrical codes for proper grounding methods.

WIRE
Refer to Specification in this Installation Section for
recommended fuse, wire sizes and type of the copper
wires. Fuse the input circuit with the recommended
super lag fuse or delay type breakers (also called
"inverse time" or "thermal/magnetic" circuit breakers).
Choose input and grounding wire size according to
local or national electrical codes. Using input wire
sizes, fuses or circuit breakers smaller than recommended may result in "nuisance" shut-offs from
welder inrush currents, even if the machine is not
being used at high currents.
INPUT VOLTAGE SELECTION
Only a qualified electrician should
connect the input leads to the FX650.
Connections should be made in
accordance with all local and national electrical
codes and the connection diagram located on
the inside of the reconnect/input access door
of the machine. Failure to do so may result in
bodily injury or death.
----------------------------------------------------------------------
INPUT CONNECTION
(See Figure A.1)
SUPPLy
A-4
Use a three-phase supply line. A 1.75 inch (45 mm)
diameter access hole for the input supply is located on
the case back. Remove the reconnect access panel
located on the case back and connect W, V, U and
ground according to the Input Supply Connection
Diagram decal.
Welders are shipped connected for 460 Volt input
voltage. To move this connection to a different input
voltage, see Figure A.1 which is illustrated below.
Refer to Auxiliary Reconnect Input Ranges table in
the Technical Specification Section. If the Auxiliary
lead (indicated as ‘A’) is placed in the wrong position
and power is applied to the machine, the machine will
protect itself and display an error message:
• "Err" "713 or 714" will be shown on the display.
• The control board and switch boards will blink out
error 713 or 714 on their status leds.
• The weld output will be turned off and the control
board will force itself into an idle state.
• The machine will need to have the misconnect
condition removed before it will recover. Power
must be removed prior to changing reconnect position.

RECOMMENDED ELECTRODE AND
WORk CABLE SIZES FOR ARC WELDING
General Guidelines
Connect the electrode and work cables between the
appropriate output studs of the FX650 per the following guidelines:
• Most welding applications run with the electrode
being positive (+). For those applications, connect
the electrode cable between the wire drive feed
plate and the positive (+) output stud on the power
source. Connect a work lead from the negative (-)
power source output stud to the work piece.
• When negative electrode polarity is required, such
as in some Innershield applications, reverse the output connections at the power source (electrode
cable to the negative (-) stud, and work cable to the
positive (+) stud).

The following recommendations apply to all output
polarities and weld modes:
• Select the appropriate size cables per the
“Output Cable Guidelines” (See Table A.1).
Excessive voltage drops caused by undersized
welding cables and poor connections often result in
unsatisfactory welding performance. Always use the
largest welding cables (electrode and work) that are
practical, and be sure all connections are clean and
tight.
Note: Excessive heat in the weld circuit indicates
undersized cables and/or bad connections.
• Route all cables directly to the work and wire
feeder, avoid excessive lengths and do not coil
excess cable. Route the electrode and work cables
in close proximity to one another to minimize the
loop area and therefore the inductance of the weld
circuit.
• Always weld in a direction away from the work
(ground) connection.

CONTROL CABLE CONNECTIONS
General Guidelines
Genuine Lincoln control cables should be used at all
times (except where noted otherwise). Lincoln cables
are specifically designed for the communication and
power needs of the FX650. Most are designed to be
connected end to end for ease of extension.
Generally, it is recommended that the total length not
exceed 100 feet (30.5 m). The use of non-standard
cables, especially in lengths greater than 25 feet, can
lead to communication problems (system shutdowns),
poor motor acceleration (poor arc starting), and low
wire driving force (wire feeding problems). Always use
the shortest length of control cable possible, and DO
NOT coil excess cable.
A-7
Regarding cable placement, best results will be
obtained when control cables are routed separate
from the weld cables. This minimizes the possibility of
interference between the high currents flowing
through the weld cables, and the low level signals in
the control cables.
PARALLELING
FX650 power sources may be paralleled for increased
output requirements. No kit is required for paralleling
of FX650 power sources. The FX650 can be paralleled in STICK or MULTI-WELD mode. Connect the
power sources as shown. In STICK mode set the output control of each power source to one half of the
desired arc current. (See Figure A.3)

COMMON WELDING PROCEDURES
WARNING
MAkING A WELD
The serviceability of a product or structure utilizing the welding programs is and must be the sole
responsibility of the builder/user. Many variables
beyond the control of the Manufacturer affect the
results obtained in applying these programs.
These variables include, but are not limited to,
welding procedure, plate chemistry and temperature, weldment design, fabrication methods and
service requirements. The available range of a
welding program may not be suitable for all applications, and the build/user is and must be solely
responsible for welding program selection.
The FX650 is a multi-process inverter welder. The
Weld Process Selector Switch is used to set the
desired weld mode. The FX650 has 5 selectable
welding modes:
1. DC-TIG – This is a CC (constant current) weld
mode used for the GTAW TIG welding process.
2. STICk – This is a CC (constant current) weld mode
used for the SMAW stick welding process.
3. CV-MIG – This is CV (constant voltage) weld mode
used for welding the GMAW MIG welding process
and the FCAW-GS flux cored gas shielded welding
process.
4. Multi-Weld™ – This is a mode designed to be used
with Multi-Weld equipment. This setting is also used
to access the CV-Innershield mode. See the
Operations section titled “To enable CV-Innershield
(disables Multi-Weld™)”. CV-Innershield is a CV
(constant voltage) weld mode used for welding
FCAW-SS, flux cored self-shielded welding process.
5. CV-SAW – This is a CV (constant voltage) weld
mode used for welding the SAW submerged arc
welding process
The FX650 is also capable of gouging. Gouging can
be done in either the SMAW mode or the CV and CVInnershield modes.
In addition to the weld process selector switch, a hot
start control dial, output control dial and arc control dial
are provided to setup and fine tune the welding procedure.
WELD CONTROLS AND DISPLAyS
B-8
Weld Process Selector Switch
5 Position switch used to select the welding process.
Hot Start Control Dial
• The Hot Start control regulates the starting current at
arc initiation. Hot Start can be set to “0” and no additional current is added at arc start. Increasing from 0
to 10 will increase the additional current (relative to
the preset current) that is added at arc initiation.
Arc Control Dial
• Full range selection of arc control from -10 to +10.
In CV mode, this control is an inductance control. In
stick mode, the control adjusts the arc force.
Output Control Dial
• Output control is conducted via a single turn potentiometer.
• Adjustment is indicated by the meters.
• When in REMOTE modes, this control sets the maximum welding current. Full depression of a foot or
hand amptrol results in the preset level of current.
Voltage Display Meter
• Prior to CV operation (current flow), the meter displays desired preset voltage value (+/- .5V).
• Prior to STICK or TIG operation, the meter displays
the Open Circuit Voltage of the Power Source or
three dashes if the output has not been turned on.
• During welding, this meter displays actual average
volts.
• After welding, the meter holds the actual voltage
value for 5 seconds. The displays blink indicating that
the machine is in the "Hold" period.
• Output adjustment while in the "Hold" period results
in the "prior to operation" characteristics.
Amperage Display Meter
• Prior to STICK or TIG operation (current flow), the
meter displays preset current value (either 2 amps or
+/- 3% (e.g. 3 amps on 100), whichever is greater).
• Prior to CV operation, the meter displays three dashes indicating non-presettable AMPS.
• During welding, this meter displays actual average
amps.
• After welding, the meter holds the actual current
value for 5 seconds. The displays blink indicating that
the machine is in the "Hold" period.
• Output adjustment while in the "Hold" period results
in the "prior to operation" characteristics.
FX650
OPERATION
B-9
Weld Terminals On/Remote Toggle Switch
• This switch determines the trigger location.
• When set to the “ON” position, the weld terminals
are at OCV (open circuit voltage) and ready to weld.
• When set to the “REMOTE” position, output is
enabled through a remote trigger.
Control - Local/Remote Toggle Switch
• Set the switch to “LOCAL” to control output at the
FX650 via the Output Control dial.
• Set the switch to “REMOTE” to control output via a
remote device connected to the 3-pin remote connector or a wire feeder connected to the 14-pin connector.
Wire Feeder Selector Switch
• This switch configures wire feeder supply voltage in
the 14 pin connector to either 42 volt or 115 volt.
• If the switch is in the incorrect position for the
attached wire feeder, there will be no power supplied to the wire feeder.
Wire Feeder Voltmeter Polarity Switch
• The switch provides a work connection for wire
feeder voltmeters. Place the switch in the position of
the electrode polarity indicated by the decal. The
switch does not change the welding polarity.
Thermal Light
• This status light indicates when the power source
has been driven into thermal overload. If the output
terminals were "ON", the output will be turned back
on once the unit cools down to an acceptable temperature level. If the unit was operating in the
"REMOTE" mode, the trigger will need to be opened
before or after the thermal has cleared and closed
after the machine has cooled down to an acceptable
temperature to establish output.

VRD™ is active:
• A green light indicates the OCV (open circuit voltage) is less than 35V peak.
• A red light indicates the OCV is at or above 35V
peak.
• Both lights will illuminate for 5 seconds at power up.
For each weld mode, the VRD™ lights function as
shown in Table B.1:
BASIC MODES OF OPERATION
STICk
This weld mode is a constant current (CC) mode featuring continuous control from 15 – 815 amps. It is
intended for the SMAW stick welding processes and
arc gouging.
Output Control Local/Remote – When the control is
set to “LOCAL” (no remote potentiometer/control
plugged into the 3 pin or 14 pin connectors), the output is controlled through the Output Control Dial on
the front of the FX650. Set this switch to “REMOTE”
when an external potentiometer/control is connected.
• When a remote potentiometer is connected, the
output control on the FX650 and the remote act as

OPERATION
Hot Start - The Hot Start control regulates the starting
current at arc initiation. Hot Start can be set to “0”
and no additional current is added at arc start.
Increasing from 0 to 10 will increase the additional
current (relative to the preset current) that is added at
arc initiation.
Arc Control - The Arc Control regulates the Arc Force
to adjust the short circuit current. The minimum setting
(-10) will produce a "soft" arc and will produce minimal
spatter. The maximum setting (+10) will produce a
"crisp" arc and will minimize electrode sticking.
Weld Terminals On/Remote – Set to “ON” and the
machine is in the ready to weld state.

• Only Qualified personnel should
perform this maintenance.
• Turn the input power OFF at the
disconnect switch or fuse box before
working on this equipment.
• Do not touch electrically hot parts.

VISUAL INSPECTION
Thermal Protection
Thermostats protect the machine from excessive
operating temperatures. Excessive temperatures may
be caused by a lack of cooling air or operating the
machine beyond the duty cycle and output rating. If
excessive operating temperature should occur, the
thermostat will prevent output voltage or current. The
meter will remain energized during this time.
Thermostats are self-resetting once the machine cools
sufficiently. If the thermostat shutdown was caused by
excessive output or duty cycle and the fan is operating
normally, the Power Switch may be left on and the
reset should occur within a 15 minute period.
Clean interior of machine with a low pressure air
stream. Make a thorough inspection of all components. Look for signs of overheating, broken leads or
other obvious problems. Many problems can be
uncovered with a good visual inspection.
ROUTINE MAINTENANCE
VRD™ Functionality should be checked once per day
or once per shift. VRD™ functionality can be verified
by the indicator lights on the front of the power source.
One of the lights will be illuminated at all times when
VRD™ is enabled. No lights will be illuminated when
VRD™ is disabled. VRD™ can be verified by cycling
power as well. When VRD™ is enabled, the VRD™
indicator lights will illuminate for 5 seconds at power
up and one light will remain illuminated.
1. Every 6 months or so the machine should be
cleaned with a low pressure airstream. Keeping the
machine clean will result in cooler operation and
higher reliability. Be sure to clean these areas:
• All printed circuit boards
• Power switch
• Main transformer
• Heatsink fins
• Input rectifier
• Auxiliary transformer
• Reconnect switch area
• Fan (blow air through the rear louvers)
2. Examine the sheet metal case for dents or breakage. Repair the case as required. Keep the case
in good condition to insure that high voltage parts
are protected and correct spacings are maintained. All external sheet metal screws must be in
place to insure case strength and electrical ground
continuity.
