BE SURE THAT ALL INSTALLATION, OPERATION,MAINTENANCE AND REPAIR PROCEDURES AREPERFORMED ONLY BY QUALIFIED INDIVIDUALS.

FOR ENGINE POWEREDEQUIPMENT.

1.a. Turn the engine off before troubleshootingand maintenance work unless themaintenance work requires it to be running.

1.b. Operate engines in open, well-ventilatedareas or vent the engine exhaust fumes outdoors.

1.c. Do not add the fuel near an open flamewelding arc or when the engine is running.Stop the engine and allow it to cool beforerefueling to prevent spilled fuel fromvaporizing on contact with hot engine partsand igniting. Do not spill fuel when fillingtank. If fuel is spilled, wipe it up and do not start engine untilfumes have been eliminated.

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 orrepairing equipment.

1.e. In some cases it may be necessary to remove safety guards toperform required maintenance. Remove guards only whennecessary and replace them when the maintenance requiringtheir removal is complete. Always use the greatest care whenworking near moving parts.

1.f. Do not put your hands near the engine fan. Do not attempt tooverride the governor or idler by pushing on the throttle controlrods while the engine is running.

1.g. To prevent accidentally starting gasoline engines while turningthe engine or welding generator during maintenance work,disconnect the spark plug wires, distributor cap or magneto wireas appropriate.

1.h. To avoid scalding, do not remove the radiatorpressure cap when the engine is hot.

ELECTRIC ANDMAGNETIC FIELDS MAYBE DANGEROUS

2.a. Electric current flowing through any conductorcauses 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 physicianbefore welding.

2.c. Exposure to EMF fields in welding may have other health effectswhich are now not known.

2.d. All welders should use the following procedures in order tominimize exposure to EMF fields from the welding circuit:

2.d.1. Route the electrode and work cables together - Securethem 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 workcables. If the electrode cable is on your right side, thework cable should also be on your right side.

2.d.4. Connect the work cable to the workpiece as close as pos-sible to the area being welded.

2.d.5. Do not work next to welding power source.

SAFETY

Safety 02 of 04 - 06/15/2016

ELECTRIC SHOCK CAN KILL.

3.a. The electrode and work (or ground) circuits areelectrically “hot” when the welder is on. Donot touch these “hot” parts with your bare skin or wet clothing.Wear dry, hole-free gloves to insulate hands.

3.b. Insulate yourself from work and ground using dry insulation.Make certain the insulation is large enough to cover your full areaof physical contact with work and ground.

In addition to the normal safety precautions, ifwelding must be performed under electricallyhazardous conditions (in damp locations or whilewearing wet clothing; on metal structures such asfloors, gratings or scaffolds; when in crampedpositions such as sitting, kneeling or lying, if thereis a high risk of unavoidable or accidental contactwith the workpiece or ground) use the followingequipment:

• 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 weldinggun are also electrically “hot”.

3.d. Always be sure the work cable makes a good electricalconnection with the metal being welded. The connection shouldbe 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 andwelding machine in good, safe operating condition. Replacedamaged insulation.

3.g. Never dip the electrode in water for cooling.

3.h. Never simultaneously touch electrically “hot” parts of electrodeholders connected to two welders because voltage between thetwo can be the total of the open circuit voltage of bothwelders.

3.i. When working above floor level, use a safety belt to protectyourself from a fall should you get a shock.

3.j. Also see It ems 6.c. and 8.

ARC RAYS CAN BURN.

4.a. Use a shield with the proper filter and cover plates to protect youreyes from sparks and the rays of the arc when welding orobserving open arc welding. Headshield and filter lens shouldconform to ANSI Z87. I standards.

4.b. Use suitable clothing made from durable flame-resistant materialto protect your skin and that of your helpers from the arc rays.

4.c. Protect other nearby personnel with suitable, non-flammablescreening and/or warn them not to watch the arc nor exposethemselves to the arc rays or to hot spatter or metal.

FUMES AND GASESCAN BE DANGEROUS.

5.a. Welding may produce fumes and gaseshazardous to health. Avoid breathing these fumes and gases.When welding, keep your head out of the fume. Use enoughventilation and/or exhaust at the arc to keep fumes and gasesaway from the breathing zone. When welding hardfacing(see instructions on container or SDS) or on leador cadmium plated steel and other metals orcoatings which produce highly toxic fumes, keepexposure as low as possible and within applicableOSHA PEL and ACGIH TLV limits using localexhaust or mechanical ventilation unless exposureassessments indicate otherwise. In confinedspaces or in some circumstances, outdoors, arespirator may also be required. Additionalprecautions are also required when welding on galvanized steel.

5. b. The operation of welding fume control equipment is affected byvarious factors including proper use and positioning of theequipment, maintenance of the equipment and the specificwelding procedure and application involved. Worker exposurelevel should be checked upon installation and periodicallythereafter to be certain it is within applicable OSHA PEL andACGIH TLV limits.

5.c. Do not weld in locations near chlorinated hydrocarbon vaporscoming from degreasing, cleaning or spraying operations. Theheat and rays of the arc can react with solvent vapors to formphosgene, a highly toxic gas, and other irritating products.

5.d. Shielding gases used for arc welding can displace air and causeinjury or death. Always use enough ventilation, especially inconfined areas, to insure breathing air is safe.

5.e. Read and understand the manufacturer’s instructions for thisequipment and the consumables to be used, including theSafety Data Sheet (SDS) and follow your employer’s safetypractices. SDS forms are available from your weldingdistributor or from the manufacturer.

5.f. Also see item 1.b.

SAFETY

Safety 03 of 04 - 06/15/2016

WELDING AND CUTTINGSPARKS CAN CAUSEFIRE OR EXPLOSION.

6.a. Remove fire hazards from the welding area. Ifthis is not possible, cover them to prevent the welding sparksfrom starting a fire. Remember that welding sparks and hotmaterials from welding can easily go through small cracks andopenings 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, specialprecautions 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 istouching the work or ground. Accidental contact can causeoverheating and create a fire hazard.

6.d. Do not heat, cut or weld tanks, drums or containers until theproper 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 SafePractices for the Preparation for Welding and Cutting ofContainers 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 orwelding. They may explode.

6.f. Sparks and spatter are thrown from the welding arc. Wear oil freeprotective garments such as leather gloves, heavy shirt, cufflesstrousers, high shoes and a cap over your hair. Wear ear plugswhen welding out of position or in confined places. Always wearsafety glasses with side shields when in a welding area.

6.g. Connect the work cable to the work as close to the welding areaas practical. Work cables connected to the building framework orother locations away from the welding area increase thepossibility of the welding current passing through lifting chains,crane cables or other alternate circuits. This can create firehazards 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 DuringWelding, Cutting and Other Hot Work”, available from NFPA, 1Batterymarch Park, PO box 9101, Quincy, MA 022690-9101.

6.j. Do not use a welding power source for pipe thawing.

CYLINDER MAY EXPLODE IFDAMAGED.

7.a. Use only compressed gas cylinders containingthe correct shielding gas for the process usedand properly operating regulators designed forthe gas and pressure used. All hoses, fittings,etc. should be suitable for the application andmaintained in good condition.

7.b. Always keep cylinders in an upright position securely chained toan undercarriage or fixed support.

7.c. Cylinders should be located:

• Away from areas where they may be struck or subjectedto physical damage.

• A safe distance from arc welding or cutting operationsand any other source of heat, sparks, or flame.

7.d. Never allow the electrode, electrode holder or any otherelectrically “hot” parts to touch a cylinder.

7.e. Keep your head and face away from the cylinder valve outletwhen opening the cylinder valve.

7.f. Valve protection caps should always be in place and hand tightexcept 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 forSafe Handling of Compressed Gases in Cylinders,” available fromthe Compressed Gas Association, 14501 George Carter WayChantilly, VA 20151.

VRD™ (VOLTAGE REDUCTION DEVICE)The VRD™ feature provides additional safety in the Stickmode. The VRD™ reduces the OCV (Open Circuit Voltage)at the welding output terminals while not welding to lessthan 35VDC peak. The VRD™ requires that the welding cable connections bekept in good electrical condition because poor connectionswill contribute to poor starting. Having good electrical con-nections also limits the possibility of other safety issuessuch 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 thecontrol P.C. board. Dip switch setting will differ dependingon input voltage.The control board and dip switches can be accessed byremoving the case top and side as shown in the OperationSection figure B.3.SELECT SUITABLE LOCATIONLOCATION AND VENTILATION FOR COOLINGPlace the welder where clean cooling air can freelycirculate in through the rear louvers and out throughthe case sides. Dirt, dust, or any foreign material thatcan be drawn into the welder should be kept at a mini-mum. Failure to observe these precautions can resultin excessive operating temperatures and nuisanceshutdowns.

TILTINGPlace the machine directly on a secure, level surfaceor on a recommended undercarriage. The machinemay topple over if this procedure is not followed.

CAUTION

A-4INSTALLATION A-4INPUT FUSE AND SUPPLy WIRECONSIDERATIONS

Refer to Specification in this Installation Section forrecommended fuse, wire sizes and type of the copperwires. Fuse the input circuit with the recommendedsuper lag fuse or delay type breakers (also called"inverse time" or "thermal/magnetic" circuit breakers).Choose input and grounding wire size according tolocal or national electrical codes. Using input wiresizes, fuses or circuit breakers smaller than recom-mended may result in "nuisance" shut-offs fromwelder inrush currents, even if the machine is notbeing used at high currents.

INPUT VOLTAGE SELECTION

Welders are shipped connected for 460 Volt inputvoltage. To move this connection to a different inputvoltage, see Figure A.1 which is illustrated below.Refer to Auxiliary Reconnect Input Ranges table inthe Technical Specification Section. If the Auxiliarylead (indicated as ‘A’) is placed in the wrong positionand power is applied to the machine, the machine willprotect itself and display an error message:• "Err" "713 or 714" will be shown on the display. • The control board and switch boards will blink outerror 713 or 714 on their status leds.• The weld output will be turned off and the controlboard will force itself into an idle state.• The machine will need to have the misconnectcondition removed before it will recover. Powermust be removed prior to changing reconnect posi-tion.

ELECTRIC SHOCk can kill.

Only a qualified electrician shouldconnect the input leads to the FX650.Connections should be made in

accordance with all local and national electricalcodes and the connection diagram located onthe inside of the reconnect/input access doorof the machine. Failure to do so may result inbodily injury or death.----------------------------------------------------------------------

RECOMMENDED ELECTRODE ANDWORk CABLE SIZES FOR ARC WELDING

General GuidelinesConnect the electrode and work cables between theappropriate output studs of the FX650 per the follow-ing guidelines:

• Most welding applications run with the electrodebeing positive (+). For those applications, connectthe electrode cable between the wire drive feedplate and the positive (+) output stud on the powersource. Connect a work lead from the negative (-)power source output stud to the work piece.

• When negative electrode polarity is required, suchas in some Innershield applications, reverse the out-put connections at the power source (electrodecable to the negative (-) stud, and work cable to thepositive (+) stud).

The following recommendations apply to all outputpolarities and weld modes:

• Select the appropriate size cables per the“Output Cable Guidelines” (See Table A.1).Excessive voltage drops caused by undersizedwelding cables and poor connections often result inunsatisfactory welding performance. Always use thelargest welding cables (electrode and work) that arepractical, and be sure all connections are clean andtight.

Note: Excessive heat in the weld circuit indicatesundersized cables and/or bad connections.• Route all cables directly to the work and wire

feeder, avoid excessive lengths and do not coilexcess cable. Route the electrode and work cablesin close proximity to one another to minimize theloop area and therefore the inductance of the weldcircuit.

• Always weld in a direction away from the work(ground) connection.

** Tabled values are for operation at ambient temperatures of 104°F(40°C) and below. Applications above 104°F(40°C) may require cableslarger than recommended, or cables rated higher than 167°F(75°C).

CONTROL CABLE CONNECTIONS

General GuidelinesGenuine Lincoln control cables should be used at alltimes (except where noted otherwise). Lincoln cablesare specifically designed for the communication andpower needs of the FX650. Most are designed to beconnected end to end for ease of extension.Generally, it is recommended that the total length notexceed 100 feet (30.5 m). The use of non-standardcables, especially in lengths greater than 25 feet, canlead to communication problems (system shutdowns),poor motor acceleration (poor arc starting), and lowwire driving force (wire feeding problems). Always usethe shortest length of control cable possible, and DONOT coil excess cable.

Regarding cable placement, best results will beobtained when control cables are routed separatefrom the weld cables. This minimizes the possibility ofinterference between the high currents flowingthrough the weld cables, and the low level signals inthe control cables.

PARALLELING

FX650 power sources may be paralleled for increasedoutput requirements. No kit is required for parallelingof FX650 power sources. The FX650 can be paral-leled in STICK or MULTI-WELD mode. Connect thepower sources as shown. In STICK mode set the out-put control of each power source to one half of thedesired arc current. (See Figure A.3)

COMMON WELDING PROCEDURES

MAkING A WELDThe serviceability of a product or structure utiliz-ing the welding programs is and must be the soleresponsibility of the builder/user. Many variablesbeyond the control of the Manufacturer affect theresults obtained in applying these programs.These variables include, but are not limited to,welding procedure, plate chemistry and tempera-ture, weldment design, fabrication methods andservice requirements. The available range of awelding program may not be suitable for all appli-cations, and the build/user is and must be solelyresponsible for welding program selection.

The FX650 is a multi-process inverter welder. TheWeld Process Selector Switch is used to set thedesired weld mode. The FX650 has 5 selectablewelding modes: 1. DC-TIG – This is a CC (constant current) weldmode used for the GTAW TIG welding process.

2. STICk – This is a CC (constant current) weld modeused for the SMAW stick welding process.

3. CV-MIG – This is CV (constant voltage) weld modeused for welding the GMAW MIG welding processand the FCAW-GS flux cored gas shielded weldingprocess.

4. Multi-Weld™ – This is a mode designed to be usedwith Multi-Weld equipment. This setting is also usedto access the CV-Innershield mode. See theOperations section titled “To enable CV-Innershield(disables Multi-Weld™)”. CV-Innershield is a CV(constant voltage) weld mode used for weldingFCAW-SS, flux cored self-shielded welding process.

5. CV-SAW – This is a CV (constant voltage) weldmode used for welding the SAW submerged arcwelding process

The FX650 is also capable of gouging. Gouging canbe done in either the SMAW mode or the CV and CV-Innershield modes.In addition to the weld process selector switch, a hotstart control dial, output control dial and arc control dialare provided to setup and fine tune the welding proce-dure.

WELD CONTROLS AND DISPLAyS

Weld Process Selector Switch5 Position switch used to select the welding process.

Hot Start Control Dial• The Hot Start control regulates the starting current atarc initiation. Hot Start can be set to “0” and no addi-tional current is added at arc start. Increasing from 0to 10 will increase the additional current (relative tothe 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. Instick mode, the control adjusts the arc force.

Output Control Dial• Output control is conducted via a single turn poten-tiometer.• Adjustment is indicated by the meters.• When in REMOTE modes, this control sets the maxi-mum welding current. Full depression of a foot orhand amptrol results in the preset level of current.

Voltage Display Meter• Prior to CV operation (current flow), the meter dis-plays desired preset voltage value (+/- .5V).• Prior to STICK or TIG operation, the meter displaysthe Open Circuit Voltage of the Power Source orthree dashes if the output has not been turned on.• During welding, this meter displays actual averagevolts.• After welding, the meter holds the actual voltagevalue for 5 seconds. The displays blink indicating thatthe machine is in the "Hold" period.• Output adjustment while in the "Hold" period resultsin the "prior to operation" characteristics.

Amperage Display Meter• Prior to STICK or TIG operation (current flow), themeter 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 dash-es indicating non-presettable AMPS.• During welding, this meter displays actual averageamps.• After welding, the meter holds the actual currentvalue for 5 seconds. The displays blink indicating thatthe machine is in the "Hold" period.• Output adjustment while in the "Hold" period resultsin the "prior to operation" characteristics.

PERIODIC MAINTENANCE

Thermal ProtectionThermostats protect the machine from excessiveoperating temperatures. Excessive temperatures maybe caused by a lack of cooling air or operating themachine beyond the duty cycle and output rating. Ifexcessive operating temperature should occur, thethermostat will prevent output voltage or current. Themeter wil l remain energized during this t ime.Thermostats are self-resetting once the machine coolssufficiently. If the thermostat shutdown was caused byexcessive output or duty cycle and the fan is operatingnormally, the Power Switch may be left on and thereset should occur within a 15 minute period.

WARNING

VISUAL INSPECTION

Clean interior of machine with a low pressure airstream. Make a thorough inspection of all compo-nents. Look for signs of overheating, broken leads orother obvious problems. Many problems can beuncovered with a good visual inspection.

ROUTINE MAINTENANCEVRD™ Functionality should be checked once per dayor once per shift. VRD™ functionality can be verifiedby the indicator lights on the front of the power source.One of the lights will be illuminated at all times whenVRD™ is enabled. No lights will be illuminated whenVRD™ is disabled. VRD™ can be verified by cyclingpower as well. When VRD™ is enabled, the VRD™indicator lights will illuminate for 5 seconds at powerup and one light will remain illuminated.

1. Every 6 months or so the machine should becleaned with a low pressure airstream. Keeping themachine clean will result in cooler operation andhigher 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 break-age. Repair the case as required. Keep the casein good condition to insure that high voltage partsare protected and correct spacings are main-tained. All external sheet metal screws must be inplace to insure case strength and electrical groundcontinuity.
