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

SAFETY

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

heir removal is complete. Always use the greatest care when

t 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

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.b. EMF fields may interfere with some pacemakers, and welders having a pacemaker should consult their physician before welding.

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.

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.

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

f physical contact with work and ground.

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

two can be the total of the open circuit voltage of both welders.

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

between the

ARC RAYS CAN BURN.

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.

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.

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.

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 It ems 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

rom starting a fire. Remember that welding sparks and hot

f 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.

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,

tc. should be suitable for the application and

e 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.

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.

SAFETYDUAL VANTAGE®700

Electromagnetic Compatibility (EMC)

onformance

Products displaying the CE mark are in conformity with European Community Council Directive of 15 Dec 2004 on the approximation of the laws of the Member States relating to electromagnetic compatibility, 2004/108/EC. It was manufactured in conformity with a national standard that implements a harmonized standard: EN 60974-10 Electromagnetic Compatibility (EMC) Product Standard for Arc Welding Equipment. It is for use with other Lincoln Electric equipment. It is designed for industrial and professional use.

Introduction

All electrical equipment generates small amounts of electromagnetic emission. Electrical emission may be transmitted through power lines or radiated through space, similar to a radio transmitter. When emissions are received by other equipment, electrical interference may result. Electrical emissions may affect many kinds of electrical equipment; other nearby welding equipment, radio and TV reception, numerical controlled machines, telephone systems, computers, etc. Be aware that interference may result and extra precautions may be required when a welding power source is used in a domestic establishment.

Installation and Use

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 (grounding) the welding circuit, see Note. In other cases it could involve construction of an electromagnetic screen enclosing the power source and the work complete with associated input filters. In all cases electromagnetic disturbances must be reduced to the point where they are no longer troublesome.

Note: The welding circuit may or may not be earthed for safety reasons according to national

codes. Changing the earthing arrangements should only be authorized by a person who is competent to access 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.

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:

a) other supply cables, control cables, signaling and telephone cables; above, below and adjacent to the

welding equipment;

b) radio and television transmitters and receivers;

c) computer and other control equipment;

d) safety critical equipment, e.g., guarding of industrial equipment;

e) the health of the people around, e.g., the use of pacemakers and hearing aids;

f) equipment used for calibration or measurement

g) 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;

h) the time of day that welding or other activities are to be carried out.

SAFETYDUAL VANTAGE®700

Electromagnetic Compatibility (EMC)

he size of the surrounding area to be considered will depend on the structure of the building and other

T activities that are taking place. The surrounding area may extend beyond the boundaries of the premises.

Methods of Reducing Emissions

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.

Maintenance of the 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 manufacturers instructions. In particular, the spark gaps of arc striking and stabilizing devices should be adjusted and maintained according to the manufacturer’s recommendations.

Welding Cables

The welding cables should be kept as short as possible and should be positioned close together, running at or close to floor level.

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 these metallic components and the electrode at the same time. The operator should be insulated from all such bonded metallic components.

Earthing of the Workpiece

Where the workpiece is not bonded to earth for electrical safety, not connected to earth because of its size and position, e.g., ships 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 be made by a 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.

Screening and Shielding

Selective screening and shielding of other cables and equipment in the surrounding area may alleviate problems of interference. Screening of the entire welding installation may be considered for special applications

SAFETY PRECAUTIONS

WARNING

Do not attempt to use this equipment until you have thoroughly read the engine manufacturer’s manual supplied with your welder. It includes important safety precautions, detailed engine

tarting, operating and maintenance instructions,

s and parts lists.

------------------------------------------------------------------------

ELECTRIC SHOCK can kill.

• Do not touch electrically live parts or electrode with skin or wet clothing.

• Insu l ate y o urself from wo r k an d ground

• Always wear dry insulating gloves.

------------------------------------------------------------------------

ENGINE EXHAUST can kill.

• Use in open, well ventilated areas or vent exhaust outside.

------------------------------------------------------------------------

MOVING PARTS can injure.

• Do not operate with doors open or guards off.

• Stop engine before servicing.

• Keep away from moving parts.

------------------------------------------------------------------------

See additional warning information at

front of this operator’s manual.

Only qualified personnel should install, use, or service this equipment.

VRD (VOLTAGE REDUCTION DEVICE)

The VRD feature provides additional safety in the CC-Stick mode especially in an environment with a higher risk of electric shock such as wet areas and hot humid sweaty conditions.

The VRD reduces the OCV (Open Circuit Voltage) at the welding output terminals while not welding to less than 30V DC when the resistance of the output circuit is above 200Ω (ohms).

FIGURE A.1

LOCATION AND VENTILATION

The welder should be located to provide an unrestricted flow of clean, cool air to the cooling air inlets and to avoid restricting the cooling air outlets. Also, locate the welder so that the engine exhaust fumes are properly vented to an outside area.

CAUTION

DO NOT MOUNT OVER COMBUSTIBLE SURFACES Where there is a combustible surface directly under stationary or fixed electrical equipment, that surface should be covered with a steel plate at least .06”(1.6mm) thick, which should extend not less than 5.90”(150mm) beyond the equipment on all sides.

------------------------------------------------------------------------

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 the VRD switch in the “Off” position. To turn it “On” or “Off”:

• Turn the engine “Off”.

• Disconnect the negative battery cable.

• Lower the control panel by removing 4 front panel screws. (See Figure A.1)

• Place the VRD switch in the “On or “Off” position. (See Figure A.1)

With the VRD switch in the “On” position, the VRD lights are enabled.

STORING

1. Store the machine in a cool, dry place when it is not in use. Protect it from dust and dirt. Keep it where it can’t be accidentally damaged from construction activities, moving vehicles, and other hazards.

2. Drain the engine oil and refill with fresh 10W30 oil. Run the engine for about five minutes to circulate oil to all the parts. See the MAINTENANCE section of this manual for details on changing oil.

3. Remove the battery, recharge it, and adjust the electrolyte level. Store the battery in a dry, dark place.

A-2

INSTALLATIONDUAL VANTAGE®700

STACKING

DUAL VANTAGE®700 machines cannot be stacked.

ANGLE OF OPERATION

To achiev e o ptim um eng ine per form ance th e DUAL VANTAGE®700 should be run in a level position.

The maximum angle of operation for the machine is 35 degrees continuous in all directions.

When operating the welder at an angle, provisions must be made for checking and maintaining the oil level at the normal (FULL) oil capacity. Also the effective fuel capacity will be slightly less than the specified 25 gal.(94.6 ltrs.).

LIFTING

The

DUAL VANTAGE®700

WELDING TERMINALS

The DUAL VANTAGE®700 is equipped with a toggle switch for selecting "hot" welding terminals when in the "WELD TERMINALS ON" position or "cold" welding termi n a l s wh e n in the "REMOT E L Y CO N TROLLED" position.

WELDING OUTPUT CABLES

With the engine off, route the electrode and work cables thru the strain relief bracket provided on the front of the base and connect to the terminals provided. These connections should be checked periodically and tightened if necessary.

WARNING

• Be grounded to the frame of the welder using a grounded type plug or be double insulated.

• Do not ground the machine to a pipe that carries explosive or combustible material.

------------------------------------------------------------------------

When this welder is mounted on a truck or trailer, its frame must be securely connected to the metal frame of the vehicle. When this engine driven welder is connected to premises wiring such as that in a home or shop, its frame must be connected to the system earth ground. See further connection instructions in the section entitled “Standby Power Connections” as well as the a r ticle o n groun d i n g in the la test Na tional Electrical Code and the local codes.

In general, if the machine is to be grounded, it should be connected with a #8 or larger copper wire to a solid earth ground such as a metal ground stake going into the ground for at least 10 Feet or to the metal framework of a building which has been effectively grounded.

The National Electric Code lists a number of alternate means of grounding electrical equipment. A machine grounding stud marked with the symbol is provided on the front of the welder.

INSTALLATIONDUAL VANTAGE®700

REMOTE CONTROL

The DUAL VANTAGE®700 is equipped with a 6-pin and a 14-pin connector. The 6-pin connector is for

onnecting the K857 or K857-1 Remote Control or for

c TIG welding, the K870 foot Amptrol or the K963-3

and Amptrol. When in the CC-STICK, ARC GOUG-

h ING or CV-WIRE modes and when a remote control is connected to the 6-pin Connector, the auto-sensing circuit automatically switches the OUTPUT control from control at the welder to remote control. When in TOUCH START TIG mode and when a Amptrol is connected to the 6-Pin Connector, the OUTPUT dial is used to set the maximum current range of the CURRENT CONTROL of the Amptrol.

When in the DOWNHILL PIPE mode and when a remote control is connected to the 6-Pin or 14-Pin connector, the output control is used to set the maximum current range of the remote.

EXAMPLE: When the OUTPUT CONTROL on the welder is set to 200 amps the current range on the remote control will be 40-200 amps, rather than the full 40-300 amps. Any current range that is less than the full range provides finer current resolution for more fine tuning of the output.

In the CV-WIRE mode, if the feeder being used has a voltage control when the wire feeder control cable is connected to the 14-Pin Connector, the auto-sensing circuit automatically makes OUTPUT CONTROL inactive a nd the wire fe eder vo ltag e contr ol activ e. Otherwise, the OUTPUT CONTROL is used to preset the voltage.

The 14-pin connector is used to directly connect a wire feeder control cable. In the CV-WIRE mode, when the control cable is connected to the 14-pin connector, the auto-sensing circuit automatically makes the Output Control inactive and the wire feeder voltage control active.

WARNING

NOTE: When a wire feeder with a built in welding voltage control is connected to the 14-pin connector, do not connect anything to the 6-pin connector.

------------------------------------------------------------------------

AUXILIARY POWER RECEPTACLES

Start the engine and set the “IDLER” control switch to the “High Idle” mode. Voltage is now correct at the receptacles for auxiliary power. This must be done before a tripped GFCI can be reset properly. See the MAINTENANCE section for more detailed information on testing and resetting the GFCI.

The auxiliary power of the DUAL VANTAGE® 700 consists of two 20 Amp-120 VAC (5-20R) duplex with GFCI protection, one 50 Amp 120/240 VAC (14-50R) receptacle and one 50 Amp 240VAC Three-Phase (15-50R) receptacle.

The auxiliary power ca p a city is 12,000 Watts Continuous of 60 Hz, single phase power. The auxiliary power capacity rating in watts is equivalent to voltamperes at unity power factor. The max permissible current of the 240 VAC output is 50 amps.

The 240 VAC output can be split to provide two separate 120 VAC outputs with a max permissible current of 50 Amps per output to two separate 120 VAC branch circuits (these circuits cannot be paralleled). Output voltage is within ± 10% at all loads up to rated capacity.

The Three-Phases auxiliary power capacity is 20,000 watts continuous. The maximum current is 48 amps.

120 V DUPLEX RECEPTACLE AND GFCI

A GFCI protects the two 120V auxiliary power.

A GFCI (Ground Fault Circuit Interrupter) is a device to protect against electric shock should a piece of defective equipment connected to it develop a ground fault. If this situation should occur, the GFCI will trip, removing voltage from the output of the receptacle. If a GFCI is tripped see the MAINTENANCE section for detailed information on testing and resetting it. A GFCI should be properly tested at least once every month.

The 120 V auxiliary power receptacles should only be used with three wire grounded type plugs or approved double insulated tools with two wire plugs. The current rating of any plug used with the system must be at least equal to the current capacity of the associated receptacle.

NOTE: The 240 V receptacle has two 120 V circuits, but are of opposite polarities and cannot be paralleled.

All auxiliary power is protected by circuit breakers. The 120V has 20 Amp circuit breakers for each duplex receptacle. The 120/240V Single Phase and the 240V ThreePhases have a 50 Amp 3-pole Circuit Breaker that disconnects both hot leads and all Three Phases simultaneously.

WELDING CONTROLS (Figure B.2)

1. OUTPUT CONTROL- The OUTPUT dial is

used to preset the output voltage or current as displayed on the digital meters for the five welding modes. When in the ARC GOUGING or CV-WIRE modes and when a remote control is connected to the 6-Pin or 14-Pin Connector, the auto-sensing circuit automatically switches the OUTPUT CONTROL from control at the welder to the remote control.

When in the TOUCH START TIG mode and when an Amptrol is connected to the 6-Pin Connector, the OUTPUT dial is used to set the maximum current range of the CURRENT CONTROL of the Amptrol.

DIGITA L OUT P UT METERS-

The di g ital meters allow the output voltage (CV-WIRE mode) or current (CC-STICK, DOWNHILL PIPE, ARC GOUGING and TIG modes) to be set prior to weld-

When in DOWNHILL PIPE and CC-STICK modes if a remote control is connected to the 6-Pin or 14 Pin Connectors, the output is controlled by the remote and the output control on the machine is used to set the maximum current range for the remote.

EXAMPLE: When the OUTPUT CONTROL on the welder is set to 200 amps the current range on the remote control will be MIN-200 amps, rather than the full MIN-MAX amps. Any current range that is less than the full range provides finer current resolution for more fine tuning of the output.

In the CV-WIRE mode, if the feeder being used has a voltage control when the wire feeder control cable is connected to the 14-Pin Connector, the autosensing circuit automatically makes OUTPUT CONTROL inactive and the wire feeder voltage control active. Otherwise, the OUTPUT CONTROL is used to preset the voltage

ing using the OUTPUT control dial. During welding, the m e t e r dis p l a y the a c t ual ou t p u t volt a g e (VOLTS) and current (AMPS). A memory feature holds the display of both meters on for seven seconds after welding is stopped. This allows the operator to read the actual current and voltage just prior to when welding was ceased.

While the display is being held the left-most decimal point in each display will be flashing. The accuracy of the meters is +/- 3%.

3. WELD MODE SELECTOR SWITCH-

(Provides five selectable welding modes)

CV-WIRE

ARC GOUGING DOWNHILL PIPE CC-STICK TOUCH START TIG

B-3

4. ARC CONTROL- The ARC CONTROL dial is active in

the CV-WIRE, CC-STICK and DOWNHILL PIPE modes, and has different functions in these modes. This control is not active in the TIG and ARC GOUGING mode.

C-STICK mode: In this mode, the ARC CONTROL dial

sets the short circuit current (arc-force) during stick welding to adjust for a soft or crisp arc. Increasing the dial from –10 (soft) to +10 (crisp) increases the short circuit current and prevents sticking of the electrode to the plate while welding. This can also increase spatter. It is recommended that the ARC CONTROL be set to the minimum number without electrode sticking. Start with a setting at 0.

DOWNHILL PIPE mode: In this mode, the ARC CONTROL dial sets the short circuit current (arc-force) during stick welding to adjust for a soft or a more forceful digging arc (crisp). Increasing the number from –10 (soft) to +10 (crisp) increases the short circuit current which results in a more forceful digging arc. Typically a forceful digging arc is preferred for root and hot passes. A softer arc is preferred for fill and cap passes where weld puddle control and deposition ("stacking" of iron) are key to fast travel speeds. It is recommended that the ARC CONTROL be set initially at 0.

These lights monitor the OCV(Open Circuit Voltage) and weld voltage at all times. In the CC-Stick mode when not welding the green light will illuminate indicating that the VRD has reduced the OCV to less than 30V. During welding the red light will illuminate whenever the arc voltage is equal to or greater than 30V. This means that the red and green light may alternate depending on the weld voltage. This is normal operation.

If the red light remains illuminated when not welding in the CC-stick mode, the VRD is not functioning properly. Please refer to your local field service shop for service. If the VRD is turned “On” and the lights don’t come “On”, refer to the trouble shooting section.

ENGINE CONTROLS:

13. RUN/STOP SWITCH -

-RUN position energizes the engine prior to starting. STOP position stops the engine. The oil pressure interlock switch prevents battery drain if the switch is left in the RUN position and the engine is not operating.

14. GLOW PLUG PUSH BUTTON -

• When pushed activates the glow plugs. Glow plug should not be activated for more than 20 seconds continuously.

15. CIRCUIT B R E A K E R- For pro tecti on o f

Battery Charging Circuit.

16. START PUSH BUTTON / ENGINE STOP BUTTON - Energizes the starter motor to crank

the engine. Shuts down engine.

17. IDLER SWITCH- Has two positions as follows:

1) In the HIGH position, the engine runs at the high idle speed controlled by the engine governor.

2) In the AUTO position, the idler operates as follows:

• When switched from HIGH to AUTO or after starting the engine, the engine will operate at full speed for approximately 12 seconds and then go to low idle speed.

• When the electrode touches the work or power is drawn for lights or tools (approximately 100 Watts minimum), the engine accelerates and operates at full speed.

• When welding ceases or the AC power load is turned off, a fixed time delay of approximately 12 seconds starts. If the welding or AC power load is not restarted before the end of the time delay, the idler reduces the engine speed to low idle speed.

• The engine will automatically return to high idle speed when there is welding load or AC power load reapplied.

18. DASH BOARD GAUGE -

The dash board gauge displays 5 gauges:

3a. OIL PRESSURE

The gauge displays the engine oil pressure

when the engine is running.

3b. ENGINE TEMPERATURE

The gauge displays the engine coolant tem-

perature.

3c. HOUR METER

The hour meter displays the total time that the

engine has been running. This meter is a useful indicator for scheduling preventive maintenance.

3d. FUEL LEVEL

Displays the level of diesel fuel in the fuel

tank.

The operator must watch the fuel level closely

to prevent running out of fuel and possibly having to bleed the system.

3e. BATTERY VOLTAGE INDICATOR

Displays the battery voltage and indicates that

the charging system is functioning properly.

19. ENGINE PROTECTION LIGHT- A warning

indicator light for Low Oil Pressure and/or Coolant Over Temperature.The light is off when the systems are functioning properly. The light will come on and the engine will shutdown when there is Low Oil Pressure and/or the Coolant is Over Temperature.

Note: The light remains off when the RUN-STOP switch is in the "ON" position prior to starting the engine. However if the engine is not started within 60 seconds the light will come on. When this happens the RUN-STOP switch must be returned to the "OFF" position to reset the engine protection system and light.

COLD WEATHER STARTING

With a fully charged battery and the proper weight oil, the engine should start satisfactorily even down to about 0°F(-18°C). If the engine must be frequently started below 10°(-12°C), it may be desirable to install the optional ether start kit (K887-1). For extreme cold conditions it may be desirable to install additional equipment such as a block heater or oil pan pad heater, etcetera.

NOTE: Extreme cold weather starting may require longer glow plug operations.

NOTE: This data is for reference only. Fuel consumption is approximate and can be influenced by many factors, including engine maintenance, environmental conditions and fuel quality.

UTY CYCLE

Duty Cycle is the percentage of time the load is being applied in a 10 minute period. For example a 60% duty cycle, represents 6 minutes of load and 4 minutes of no

oad in a 10 minute period.

ELECTRODE INFORMATION

For any electrode the procedures should be kept within the rating of the machine. For information on electrodes and their proper application see (www.lincolnelectric.com) or the appropriate Lincoln publication.

The

DUAL VANTAGE®700 range of DC stick electrodes. The MODE switch provides two stick welding settings as follows:

CONSTANT CURRENT (CC-STICK) WELDING

The CC-STICK position of the MODE switch is designed for horizontal and vertical-up welding with all types of electrodes, especially low hydrogen.

The ARC CONTROL dial sets the short circuit current (arcforce) during stick welding to adjust for a soft or crisp arc. Increasing the number from -10(soft) to +10(crisp) increases the short circuit current and prevents sticking of the electrode to the plate while welding. This can also increase spatter. It is recommended that the ARC CONTROL be set to the minimum number without electrode sticking. Start with the dial set at 0.

NOTE: Due to the low OCV with the VRD on, a very slight delay during striking of the electrodes may occur. Due to the requirement of the resistance in the circuit to be low for a VRD to operate, a good metalto-metal contact must be made between the metal core of the electrode and the job. A poor connection anywhere in the welding output circuit may limit the operation of the VRD. This includes a good connection of the work clamp to the job. The work clamp should be connected as close as practical to where the welding will be performed.

B. For Re-Striking Electrodes

Some electrodes form a cone at the end of the elec-

rode after the welding arc has been broken, particu-

t larly iron powder and low hydrogen electrodes. This

one will need to be broken off in order to have the

c metal core of the electrode make contact.

E6010 - Push, Twist in Joint, Lift

7018, E7024 - Touch, Rock Back and Forth in Joint, Lift.

Once the arc is started, normal welding technique for the application is then used.

For other electrodes the above techniques should be tried first and varied as needed to suit operator preference. The goal for successful starting is good metal to metal contact.

For indicator light operation, see Table B.1.

DOWNHILL PIPE Welding

This slope controlled setting is intended for "out-of-position" and "down hill" pipe welding where the operator would like to control the current level by changing the arc length.

The ARC CONTROL dial sets the short circuit current (arc-force) during stick welding to adjust for a soft or more forceful digging arc (crisp). Increasing the number from -10(soft) to +10(crisp) increases the short circuit current which results in a more forceful digging arc.

Typically a forceful digging arc is preferred for root and hot passes. A softer arc is preferred for fill and cap passes where weld puddle control and deposition (“stacking” of iron) are key to fast travel speeds. This can also increase spatter.

It is recommended that the ARC CONTROL be set to the minimum number without electrode sticking. Start with the dial set at 0.

NOTE: With the VRD switch in the “ON” position (See figure A.1 for location) there is no output in the DOWNHILL PIPE mode. Table B.1.

OPERATIONDUAL VANTAGE®700

TIG WELDING

The TOUCH START TIG setting of the MODE switch

s for DC TIG (Tungsten Inert Gas) welding. To initiate

i a weld, the OUTPUT CONTROL dial is first set to the

esired current and the tungsten is touched to the

d work. During the time the tungsten is touching the work there is very little voltage or current and, in general, no tungsten contamination. Then, the tungsten is gently lifted off the work in a rocking motion, which establishes the arc.

When in the TOUCH START TIG mode and when a Amptrol is connected to the 6-Pin connector the OUTPUT CONTROL dial is used to set the maximum current range of the current control of the Amptrol.

The ARC CONTROL is not active in the TIG mode. To STOP a weld, simply pull the TIG torch away from the work.

When the arc voltage reaches approximately 30 Volts the arc will go out and the machine will reset the current to the Touch Start level.

To reinitiate the arc, retouch the tungsten to the work and lift. Alternatively, the weld can be stopped by releasing the Amptrol or arc start switch.

If desired, the K930-2 TIG Module can be used with the DUAL VANTAGE®700. The settings are for reference.

DUAL VANTAGE

700 settings when using the K930-

2 TIG Module with an Amptrol or Arc Start Switch:

• Set the MODE Switch to the TOUCH START TIG setting.

• Set the "IDLER" Switch to the "AUTO" position.

• Set the "WELDING TERMINALS" switch to the "REMOTELY CONTROLLED" position.

This will keep the "Solid State" contactor open and provide a "cold" electrode until the Amptrol or Arc Start Switch is pressed.

When using the TIG Module, the OUTPUT CONTROL

on the DUAL VANTAGE

700 is used to set the maximum range of the CURRENT CONTROL on the TIG Module or an Amptrol if connected to the TIG Module.

NOTE: The TIG process is to receive a low voltage

welding process. There is no difference in operation with the VRD “On” or “Off” for this mode. For indicator light operation, see Table

B.1.

The DUAL VANTAGE

700 an be used in a wide variety of DC TIG welding applications. In general the ‘Touch Start’ feature allows contamination free starting without the use of a Hi-frequency unit.

WIRE WELDING-CV

Connect a wire feeder to the DUAL VANTAGE®700 ac cording to the in structi ons in INSTALLA TION INSTRUCTIONS Section.

The DUAL VANTAGE

700 in the CV-WIRE mode, permits it to be used with a broad range of flux cored wire (Innershield and Outershield) electrodes and solid wires for MIG welding (gas metal arc welding). Welding can be finely tuned using the ARC CONTROL. Turning the ARC CONTROL clockwise from – 10 (soft) to +10 (crisp) changes the arc from soft and washed-in to crisp and narrow. It acts as an inductance/pinch control. The proper setting depends on the procedure and operator preference. Start with the dial set at 0.

ARC GOUGING

The DUAL VANTAGE®700 can be used for arc gouging. The minimum output in the arc gouging mode is 200 Amps. For arc gouging below 200 Amps use the CC-Stick Mode. For optimal performance, set the MODE per Table B.4.

PARALLELING

hen paralleling machines in order to combine their

W outputs, all units must be operated in the CC-STICK mode only at the same output settings. To achieve this, turn the WELD MODE switch to the CC-STICK

osition. Operation in other modes may produce errat-
