ARC WELDING SAFETY INSTRUCTIONS AND WARNINGSInstruction 830001

May 8, 1996 2-1

WELDING can cause fire or explosion.

Sparks and spatter fly off from the welding arc. Theflying sparks and hot metal, weld spatter, hot work-piece, and hot equipment can cause fires and burns.Accidental contact of electrode or welding wire tometal objects can cause sparks, overheating, or fire.

1. Protect yourself and others from flying sparks and hot metal.2. Do not weld where flying sparks can strike flammable material.3. Remove all flammables within 35 ft (10.7 m) of the welding arc.

If this is not possible, tightly cover them with approved covers.4. Be alert that welding sparks and hot materials from welding can

easily go through small cracks and openings to adjacent areas.

5. Watch for fire, and keep a fire extinguisher nearby.

6. Be aware that welding on a ceiling, floor, bulkhead, or partitioncan cause fire on the hidden side.

7. Do not weld on closed containers such as tanks or drums.

8. Connect work cable to the work as close to the welding area aspractical to prevent welding current from traveling long, possiblyunknown paths and causing electric shock and fire hazards.

9. Do not use welder to thaw frozen pipes.

10. Remove stick electrode from holder or cut off welding wire atcontact tip when not in use.

11. Wear oil-free protective garments such as leather gloves, heavyshirt, cuffless trousers, high shoes, and a cap.

FLYING SPARKS AND HOT METAL cancause injury.

Chipping and grinding cause flying metal. As weldscool, they can throw off slag.

1. Wear approved face shield or safety goggles. Side shields rec-ommended.

2. Wear proper body protection to protect skin.

CYLINDERS can explode if damaged.

Shielding gas cylinders contain gas under high pres-sure. If damaged, a cylinder can explode. Since gascylinders are normally part of the welding process,be sure to treat them carefully.

1. Protect compressed gas cylinders from excessive heat, mechani-cal shocks, and arcs.

2. Install and secure cylinders in an upright position by chainingthem to a stationary support or equipment cylinder rack to preventfalling or tipping.

3. Keep cylinders away from any welding or other electrical circuits.4. Never allow a welding electrode to touch any cylinder.5. Use only correct shielding gas cylinders, regulators, hoses, and

fittings designed for the specific application; maintain them andassociated parts in good condition.

6. Turn face away from valve outlet when opening cylinder valve.7. Keep protective cap in place over valve except when cylinder is

in use or connected for use.8. Read and follow instructions on compressed gas cylinders, asso-

ciated equipment, and CGA publication P-1 listed in SafetyStandards.

ENGINES can be hazardous.

ENGINE EXHAUST GASES can kill.

Engines produce harmful exhaust gases.

1. Use equipment outside in open, well-ventilated areas.2. If used in a closed area, vent engine exhaust outside and away

from any building air intakes.

FUMES AND GASES can be hazardousto your health.

Welding produces fumes and gases. Breathing thesefumes and gases can be hazardous to your health.

1. Keep your head out of the fumes. Do not breath the fumes.2. If inside, ventilate the area and/or use exhaust at the arc to

remove welding fumes and gases.3. If ventilation is poor, use an approved air-supplied respirator.

4. Read the Material Safety Data Sheets (MSDSs) and the manu-facturer’s instruction for metals, consumables, coatings, andcleaners.

5. Work in a confined space only if it is well ventilated, or whilewearing an air-supplied respirator. Shielding gases used forwelding can displace air causing injury or death. Be sure thebreathing air is safe.

6. Do not weld in locations near degreasing, cleaning, or sprayingoperations. The heat and rays of the arc can react with vapors toform highly toxic and irritating gases.

7. Do not weld on coated metals, such as galvanized, lead, orcadmium plated steel, unless the coating is removed from theweld area, the area is well ventilated, and if necessary, whilewearing an air-supplied respirator. The coatings and any metalscontaining these elements can give off toxic fumes if welded.

NOTE: Considerations About Welding And The Effects Of Low Frequency Electric And Magnetic Fields

The following is a quotation from the General Conclusions Section of the U.S. Congress, Office of Technology Assessment, Biological Effectsof Power Frequency Electric & Magnetic Fields — Background Paper, OTA-BP-E-63 (Washington, DC: U.S. Government Printing Office, May1989): “... there is now a very large volume of scientific findings based on experiments at the cellular level and from studies with animals andpeople which clearly establish that low frequency magnetic fields can interact with, and produce changes in, biological systems. While most ofthis work is of very high quality, the results are complex. Current scientific understanding does not yet allow us to interpret the evidence in asingle coherent framework. Even more frustrating, it does not yet allow us to draw definite conclusions about questions of possible risk or tooffer clear science-based advice on strategies to minimize or avoid potential risks.”

To reduce magnetic fields in the workplace, use the following procedures:

About Pacemakers:

The above procedures are among those also normally recommended for pacemaker wearers. Consult your doctor for complete information.

1. Keep cables close together by twisting or taping them.

2. Arrange cables to one side and away from the operator.

3. Do not coil or drape cables around the body.

4. Keep welding power source and cables as far away from body aspractical.

LES VAPEURS ET LES FUMEES SONTDANGEREUSES POUR LA SANTE.

Le soudage dégage des vapeurs et des fuméesdangereuses à respirer.

1. Eloignez la tête des fumées pour éviter de les respirer.2. A l’intérieur, assurez-vous que l’aire de soudage est bien ven-

tilée ou que les fumées et les vapeurs sont aspirées à l’arc.3. Si la ventilation est inadequate, portez un respirateur à adduc-

tion d’air approuvé.4. Lisez les fiches signalétiques et les consignes du fabricant

relatives aux métaux, aux produits consummables, aux revête-ments et aux produits nettoyants.

5. Ne travaillez dans un espace confiné que s’il est bien ventilé;sinon, portez un respirateur à adduction d’air. Les gaz protec-teurs de soudage peuvent déplacer l’oxygène de l’air et ainsicauser des malaises ou la mort. Assurez-vous que l’air estpropre à la respiration.

6. Ne soudez pas à proximité d’opérations de dégraissage, denettoyage ou de pulvérisation. La chaleur et les rayons de l’arcpeuvent réagir avec des vapeurs et former des gaz hautementtoxiques et irritants.

7. Ne soudez des tôles galvanisées ou plaquées au plomb ou aucadmium que si les zones à souder ont été grattées à fond, quesi l’espace est bien ventilé; si nécessaire portez un respirateurà adduction d’air. Car ces revêtements et tout métal qui contientces éléments peuvent dégager des fumées toxiques au momentdu soudage.

DESCRIPTION OF EQUIPMENT

General DescriptionThe Model 2460 Heavy Duty CC/CV Wire Feeder

is designed to control the linear movement of 1/8inch (3.2 mm) diameter (or less) tubular weldingelectrode or 3/32 inch diameter (or less) solid weld-ing electrode. The basic feeder has been designedfor self-shielding welding electrode and does nothave a gas solenoid.

For use of non self-shielding electrode, optionalgas solenoids are available and may be installed inthis portable feeder.

Metal Inert Gas (MIG) welding process joins metalparts by electric arc which is established between afiller metal (consumable welding wire) and the work.The combination of the consumable wire with theparent metal forms the weld.

This wire feeder may be used with either a con-stant-voltage or constant-current type welding ma-chine. A transformer-rectifier, motor-generator, orengine-driven welding machine may be used.

Current Capacity and RatingThe welding current on this equipment is passed

through the feedhead assembly. Care must betaken to make sure that the connections betweenthe feedhead and the power source connectingcable as well as between the feedhead and guncable assembly connector are tight. Loose connec-tions cause excessive heating and must be avoided.

This feeder uses arc voltage for its power. Thecable connection between the feedhead and thepower source also provide a power connection forthe feeder control. The other power connection ismade through the voltage sensing lead which mustbe connected to the work terminal. Care must betaken to make sure that the power cable connectionis made between the power source and work. If thisconnection is not made, and an attempt is made tostrike an arc, serious damage to the feeder willoccur. By taking power from the welding arc, twomodes of operation result. These are termed CCand CV mode. When a constant voltage powersource is used, the input voltage to the feederremains constant and a fixed wire feed speed willresult for a given dial selection on the feeder. If eitherthe power source voltage setting or the feeder set-ting are changed, the output speed will change. Thisis called CV mode of operation. When a constant

current power source is used, the arc voltage willvary and as a result, the wire feed speed will varyfor a fixed dial setting on the feeder. This is calledCC mode of operation. When a constant currentpower source is used, an increase in arc voltage willcause an increase in wire feed speed, but an in-crease in wire feed speed causes a decrease in arcvoltage. This results in a self-regulating system sothat the feeder keeps the arc voltage constant byvarying the wire feed speed as the arc attempts tofluctuate. A switch on the back of the feeder isprovided to select between CV or CC. This switchselects proper control stability for the mode beingused. The switch does not select the mode ofoperation. The mode of operation is determined bythe type of power source being used.

The main application for this wire feeder is for CCapplication using tubular self-shielding wires. MostCC types of power sources do not have a remotecontactor control available. This means that theelectrode is always hot once the power source hasbeen turned on. It also means that the gun switchon the wire feeder does not control the powersource, but only controls the starting and stoppingof the wire feeder itself. Since the power sourceremains turned on, when the gun switch is released,care must be taken when terminating the arc. Whenthe gun switch is released, the operator must alsopull the gun away from the arc to make sure that thearc is extinguished and does not burn back into thegun tip.

Internal limiting circuitry limits the maximum speedindependent of input voltage. In addition, a slowrun-in circuit is provided which automatically re-duces the run in wire feed speed when open circuitvoltage from a CC power source is present.

NOTE: Wire feeder input is protected by a7 Amp slo-blow fuse. An 1/8 Amp fuseprotects the P.C. Board circuitry should ashort develop between the gun switch leadto electrode lead. A 5 Amp slo-blow in-linefuse inside the case protects the wire feedmotor.

Feedhead AssemblyThe feed roll drive motor is solid-state controlled

on this unit. One of either of two different motors(see Parts List for numbers of each) are used,

OPERATION

Prewelding ChecksBefore attempting to operate the Model 2460

Heavy Duty CC/CV Wire Feeder, make certain thatall installation instructions, including those for thewelding machine (power source), and the weldinggun and cable, have been carried out.

1. With the feeder properly connected to the powersource and the work cables properly connectedfrom power source to work and from feeder to work,turn on the power source.

WARNING: When the powersource is turned on, the elec-trode (welding wire) is electri-cally “hot”. Do not permit it totouch any metal or a welding arcmay be established which maybe injurious to someone’s eyes(flash) or skin (burn).

2. Select CC/CV characteristic on motor controlcircuit and set switch accordingly.

3. Determine desired operating voltage in case ofa CV power source or desired operating current incase of a CC power source and set power sourceaccordingly.

4. Set control on feeder to an approximate 3position on the dial.

NOTE: When using a CV power source,increasing dial position will increase wirefeed speed and as a result increase weld-ing current.

When using a CC power source, increasingdial position will increase wire feed speedand as a result will decrease arc voltage.

Welding1. Position the gun above the workpiece but do not

touch the electrode to the work as this will cause arcflash. With the gun in the proper position and eyesfully protected, pull the gun switch which will causean arc to be initiated.

2. Releasing the gun switch trigger will cause thewire to stop feeding. At this time the gun must bepulled away from the work in order to extinguish thearc.

3. When the welding has been completed, or at theend of the work day, it is recommended that thepower source and feeder be turned off.

CONTROL BOX ASSEMBLY NO. 376783A & 376783B

DESCRIPTION, INSTALLATION, OPERATION AND MAINTENANCE

DescriptionThe Control Box assembly is the control medium

for the operation of the Feedhead. Wire Feed Speedrate (IPM Inches-per-minute) is selected and regu-lated by the knob (potentiometer) on the front panel.The box is designed to function as a component ofthe 2000 Series Wire Feeder composite assembly,or as remote-mounted control medium, not situatedclose to the Feedhead. A side panel is available toreplace the Feedhead Mounting Plate (see Figure1) when used in a remote situation.

Controls and ConnectionsA. CV operation. When using a CV power source,

this control is used to control wire feed speed. Toincrease wire feed speed, turn the control knobclockwise. To decrease wire feed speed, turn theknob counterclockwise.

B. CC operation. When using a CC power source,this control is used to control arc voltage by varyingwire feed speed. To increase arc voltage (decreasewfs), turn knob counterclockwise. To decrease arcvoltage (increase wfs), turn knob clockwise.

NOTE: Many CC power sources have adrooping V-I characteristic. On thesetypes of power sources, the current is notexactly constant and changing the arcvoltage will also change the output cur-rent. This again becomes a self-regulat-ing stable system.

ON-OFF Rocker Switch — This switch controls theinput circuit, applying or removing the input voltageof the unit.

Gun Switch Receptacle — The gun switch controlcable connects to the gun switch receptacle (quick-disconnect type) to provide control from the gunswitch to the wire feed mechanism.

Welding Gun Cable Connector — The gun cableis connected to the wire feeder at this receptacle.Connections must always be tight.

Fuse 7 A — The unit is equipped with a 7 A MDXslow blow fuse. This fuse is rated at 125 volt andmay never be replaced with a fuse of lower voltagerating as this could cause serious damage to theequipment.

Fuse 1/8 A — Protects P.C. Board from weldingelectrode shorting to gun switch circuit.

Fuse 5 A — Protects motor from excessive stallcurrent.

Label — Identifies 5 A fuse rating and location(inside control box).

CC/CV Switch — This is a two-position switch thatcontrols the droop characteristics of the motor con-trol circuit. When in the CV position, the circuit usesIR compensation giving an almost flat speed torquecurve. When in the CC position, the IR compensa-tion is eliminated and the speed torque curve has afairly high droop. The CV position is recommendedfor all CV types of power sources. The CC positionis generally recommended when using a CC powersource. For many types of wires however, the CVposition is recommended even when a CC powersource is used.

A 12-volt gas valve and P.C. Board control theshielding gas for solid wire welding. Welding gas willflow when the gun switch is closed.

The circuit board uses the output voltage of thebridge rectifier CR1 and converts this output into a12-V DC voltage. The gas valve is a part of the total

DC to DC converter circuit and is always connectedin the circuit.

The circuit board is installed next to the motorcontrol board.

Installation

Location

The model 2460 heavy duty CC/CV wire feeder isdesigned to withstand high moisture conditions en-countered in outdoor welding applications. How-ever, the wire feeder is not waterproof and thereforeshould not be stored outdoors for extended periodsof time.

Connections

1. Make sure that the proper welding cable con-nections exist between the feeder feedhead (elec-trode) to power source and work connection topower source. Connect Feeder work lead (Figure 1)to work.

Figure 2 Connections (Rear End of Enclosure)

TIP-218CONTROL BOX ASSEMBLY NO. 376783A & 376783B

Page 2 May 29, 1996 Revised

2. Attach the gun and cable to the wire feeder byfollowing instructions found in the Owner’s Manualfor the Gun and Cable assembly.

WARNING: The welding elec-trode is electrically “Hot”. Elec-trode contact to workpiece willcause an arc with the wire feederconnected to the workpiece andgun switch depressed — feedmotor will run feeding “HOT”electrode.

Operation

Theory of OperationRefer to Connection Diagram 376784A

With the wire feeder connected to the weldingelectrode and the work terminal, turn the powersource and wire feeder on. Power is supplied intoBridge rectifier CR1. Power on the output side of theCR1 is fed to the motor control board with the properpolarity independent of the welding polarity.

When the welding gun switch (S4) is closed, itenergizes the proper components on the PC Boardand causes the motor to run. When the gun switchis opened, it removes power from the motor andshorts the armature to provide dynamic braking ofthe motor.

When the CC/CV switch (S5) is open, IR compen-sation is used on the motor control circuit. When S5is closed, the IR compensation circuit is not active.

Terminal strip TB1 is used to connect variousoptions to the feeder.

Switch S1 is used to turn the power into the feederon or off.

Resistor R1 is the control potentiometer for the unitwhich varies the output speed.

The motor control circuit on this feeder is a DC toDC converter circuit. It uses the power supply output

voltage and changes it to the proper DC voltagerequired to operate the motor. The motor is part ofthe operating circuit, and the circuit will not operateproperly if the motor is removed.

The circuit is designed for continuous operationwhen the input voltage is 30 volts or below. ManyCC power sources have an open circuit voltage of60 to 100 volts. Under these input conditions, thecircuit will operate and the motor will run. Thiscondition may exist for a period long enough to feedwire through the gun when wire spools are changed,etc., but the motor must never be allowed to operatewith open circuit voltage for prolonged periods oftime.

Options

1. Remote Contactor Control Option — This optionis externally located and connects to the feeder bymeans of a control cable which is added to thefeeder. When this option is installed, a relay isadded to the feeder and a 24-V AC gas valve optionis available.

The remote box requires 115-V AC input and inturn provides 24 V AC to the feeder as well as acontactor control relay closure to the power source.The 24 V AC is also used to allow for inching of thewire feed motor.

2. A voltmeter kit as well as an inches per minutekit are available for this unit.

3. A remote arc voltage/current control is alsoavailable which allows the user to adjust the powersource at the feeder.

Maintenance

Cleaning of the Unit

Periodically remove a side panel of the cabinet,and blow out the interior with clean, dry, com-pressed air of not more than 25 psi (172 kPa)pressure. Do not strike any of the components withthe air hose nozzle.

FEEDHEAD ASSEMBLY NO. 376799A-1, -2, -3, -4

DESCRIPTION, INSTALLATION, OPERATION AND MAINTENANCE

DescriptionThe four-roll feedhead assembly consists of four

idler gear/feed rolls (item 2, Figure 1) for varioustypes and sizes of wire. See Feed Roll Kit (375980),wire input guide (item 1), center guide (item 7),output guide (item 5), feedhead plate (item 4) andpressure arm assembly (item 6). The drive motor is115 volt DC, controlled by solid-state or variacspeed control. See the data on the particular modelwhich is found in the manual of which this TIP is apart.

Wire sizes from 0.030-inch (0.76 mm) diameter to1/8 inch (3.18 mm) may be fed with selection ofproper feed rolls. See Feed Roll Kit (Drawing375980-X, included in this manual) for feed rollconfiguration and proper feed rolls for given sizesand types of wire.

The Solenoid (Gas Control) Valve (optional) islocated on the back side of the Feedhead Plate. Afitting for gas supply extends through the back panelof the Control Box.

InstallationThe feedhead assembly becomes a part of the

modular assembly which includes a control boxassembly, and a wire support assembly which maybe mounted on a common baseplate, or remotelymounted, as on a boom unit.

Location — For best operating characteristics andlongest unit life, take care in selecting an installationsite. Avoid locations exposed to dust, high ambienttemperature, or corrosive fumes.

Connections — The electrical connections for thewire feeder are made both at the feedhead andcontrol box. The feedhead connection is made fromthe power supply terminal to the feedhead as withstandard feeders. However, the feeder motor andcontrols use the feedhead potential to supply oper-ating power for the feeder. Be sure the cable con-nection to the feedhead is tight. A loose cable willcause the feeder to malfunction.

Installation of Welding Wire Spool — See I-169 fordetails.

Adjustment of Spool Tension — Adjust the tensionon the Wire Spool so that the wire will feed freelyinto the feedhead (feed rolls), but will not “coast”when wire feeding stops. Tighten or loosen the HubTension Screw accordingly.

Threading Wire Into Feedhead — Refer to Figure2.

CAUTION: Use care when handling thespooled wire as it tends to unravel whenloosened from the spool. Grasp the endof the wire firmly; do not let it get away!Make sure the end of the wire is free ofburrs, and that it is straight.

1. Loosen the Pressure Arm Knobs, and raise thePressure Arm UP as shown in Figure 2.

2. Place the end of the wire into the Input Guide,feeding it through the guide and over the feed rollgrooves.

3. Pass the wire into the Output Guide and on intothe Gun Cable. See Owner’s Manual for the Gunand Cable Assembly.

4. Make sure that the wire is directly over thegrooves in the feed rolls and replace the PressureArm. Lock it in place with the Pressure Arm Knobs.
