The engine exhaust from this product contains chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm.

The Above For Gasoline Engines

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.

____________________________________________________

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.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.

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.

___________________________________________________

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.

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

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 of 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.

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 with electrodes which require special ventilation such as stainless or hard facing (see instructions on container or MSDS) or on lead or cadmium plated steel and other metals or coatings which produce highly toxic fumes, keep exposure as low as possible and below Threshold Limit Values (TLV) using local exhaust or mechanical ventilation. In confined spaces or in some circumstances, outdoors, a respirator may be required. Additional precautions are also required when welding on galvanized steel.

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.

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

3.j. Also see Items 6.c. and 8.

5.b.

Do not weld in locations near chlorinated hydrocarbon

coming from degreasing, cleaning or spraying operations. The heat and rays of the arc can react with solvent vapors form phosgene, a highly toxic gas, and other irritating products.

5.c. 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.d. Read and understand the manufacturer’s instructions for this

equipment and the consumables to be used, including the

material safety data sheet (MSDS) and follow your

employer’s safety practices. MSDS forms are available from

your welding distributor or from the manufacturer.

5.e. Also see item 1.b.

WELDING 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.

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 been “cleaned”. For information, purchase “Recommended Safe Practices for the 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.

Sparks and spatter are thrown from the welding arc. Wear oil

6.f. 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.

Remember that welding sparks and hot

though

they have

Preparation

for Welding and Cutting of

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 1235 Jefferson Davis Highway, Arlington, VA 22202.

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.

SAFETY

PRÉCAUTIONS DE SÛRETÉ

Pour votre propre protection lire et observer toutes les instructions et les précautions de sûreté specifiques qui parraissent dans ce manuel aussi bien que les précautions de sûreté générales suivantes:

Sûreté Pour Soudage A L’Arc

1. Protegez-vous contre la secousse électrique:

a. Les circuits à l’électrode et à la piéce sont sous tension

quand la machine à souder est en marche. Eviter toujours tout contact entre les parties sous tension et la peau nue ou les vétements mouillés. Porter des gants secs et sans trous pour isoler les mains.

b. Faire trés attention de bien s’isoler de la masse quand on

soude dans des endroits humides, ou sur un plancher metallique ou des grilles metalliques, principalement dans

les positions assis ou couché pour lesquelles une grande partie du corps peut être en contact avec la masse.

c. Maintenir le porte-électrode, la pince de masse, le câble

de soudage et la machine à souder en bon et sûr état defonctionnement.

d.Ne jamais plonger le porte-électrode dans l’eau pour le

refroidir.

e. Ne jamais toucher simultanément les parties sous tension

des porte-électrodes connectés à deux machines à souder parce que la tension entre les deux pinces peut être le total de la tension à vide des deux machines.

f. Si on utilise la machine à souder comme une source de

courant pour soudage semi-automatique, ces precautions pour le porte-électrode s’applicuent aussi au pistolet de soudage.

5. Toujours porter des lunettes de sécurité dans la zone de soudage. Utiliser des lunettes avec écrans lateraux dans les zones où l’on pique le laitier.

6. Eloigner les matériaux inflammables ou les recouvrir afin de prévenir tout risque d’incendie dû aux étincelles.

7. Quand on ne soude pas, poser la pince à une endroit isolé de la masse. Un court-circuit accidental peut provoquer un échauffement et un risque d’incendie.

8. S’assurer que la masse est connectée le plus prés possible de la zone de travail qu’il est pratique de le faire. Si on place la masse sur la charpente de la construction ou d’autres endroits éloignés de la zone de travail, on augmente le risque de voir passer le courant de soudage par les chaines de levage, câbles de grue, ou autres circuits. Cela peut provoquer des risques d’incendie ou d’echauffement des chaines et des câbles jusqu’à ce qu’ils se rompent.

9. Assurer une ventilation suffisante dans la zone de soudage. Ceci est particuliérement important pour le soudage de tôles galvanisées plombées, ou cadmiées ou tout autre métal qui produit des fumeés toxiques.

10. Ne pas souder en présence de vapeurs de chlore provenant d’opérations de dégraissage, nettoyage ou pistolage. La chaleur ou les rayons de l’arc peuvent réagir avec les vapeurs du solvant pour produire du phosgéne (gas fortement toxique) ou autres produits irritants.

11. Pour obtenir de plus amples renseignements sur la sûreté, voir le code “Code for safety in welding and cutting” CSA Standard W 117.2-1974.

2. Dans le cas de travail au dessus du niveau du sol, se protéger contre les chutes dans le cas ou on recoit un choc. Ne jamais enrouler le câble-électrode autour de n’importe quelle partie du corps.

3. Un coup d’arc peut être plus sévère qu’un coup de soliel, donc:

a. Utiliser un bon masque avec un verre filtrant approprié

ainsi qu’un verre blanc afin de se protéger les yeux du rayonnement de l’arc et des projections quand on soude ou quand on regarde l’arc.

b. Porter des vêtements convenables afin de protéger la

peau de soudeur et des aides contre le rayonnement de l‘arc.

c. Protéger l’autre personnel travaillant à proximité au

soudage à l’aide d’écrans appropriés et non-inflammables.

4. Des gouttes de laitier en fusion sont émises de l’arc de soudage. Se protéger avec des vêtements de protection libres de l’huile, tels que les gants en cuir, chemise épaisse, pantalons sans revers, et chaussures montantes.

PRÉCAUTIONS DE SÛRETÉ POUR LES MACHINES À SOUDER À TRANSFORMATEUR ET À REDRESSEUR

1. Relier à la terre le chassis du poste conformement au code de l’électricité et aux recommendations du fabricant. Le dispositif de montage ou la piece à souder doit être branché à une bonne mise à la terre.

2. Autant que possible, I’installation et l’entretien du poste seront effectués par un électricien qualifié.

3. Avant de faires des travaux à l’interieur de poste, la debrancher à l’interrupteur à la boite de fusibles.

4. Garder tous les couvercles et dispositifs de sûreté à leur place.

2-Step or 4-Step Trigger Modes - Unit operates only

when trigger is pressed in 2-Step mode (normal) operation. 4-Step Trigger Mode eliminates the need to hold the gun trigger closed while welding. Both models have user selectable 4-step with crater fill, or as shipped, 4-step with current interlock.

Gas Preflow and Postflow Timers - Allows setting of shielding gas preflow time (0-2.5 seconds) before welding arc starts, and gas postflow time (0-9.9 seconds), after welding arc stops.

Crater Fill - Allows setting of crater fill WFS (when 4step with crater fill trigger mode is selected), independent of weld, cold feed, and run-in speeds.

4-Roll Drive - Both models employ 4-Roll Drive, with 2 driven rolls, providing optimal feeding force for problem feeding situations, with low wire deformation for improved feeding of soft wires.

Control Features:

Microcomputer Based Control - Provides precise

setting and display of all parameters and precision timing functions. Optimizes wire drive control for crisp acceleration and smooth response with precise repeatability. Allows synergic control of various welding processes by communicating information over a serial link to the compatible power source.

Display and Indicator Lights - Wide temperature range, long life, 3-1/2 digit 7-segment LED display with .56” (14.2mm) character height permits easy viewing even from long gun cable distances. Individual red indicator lights are high intensity LED’s for viewing at almost any angle. Mode and Timer function keys and indicator lights are concealed behind a hinged “drop-door” cover.

Encoder Controls - Rotating encoders provide continuous knob control for setting both Wire Feed Speed and Volts/Trim procedures.

Procedure Switch - Permits selection of A or B procedures, as set by the procedure controls and memory pair selected at the Power Wave power source. Setting switch to center “Gun Switch” position allows selection of A or B procedures with the optional Dual Procedure Switch.

Keypad - Consists of 7 membrane keys with tactilefeel embossed domes. All keys are generously spaced to provide easy selection, even if wearing welding gloves.

Selectable Burnback Time - Provides front panel selection of 6 Burnback times. This feature provides selectable Burnback time (default = 0ms) if required to prevent electrode from sticking in weld puddle at finish of weld.

Spot Mode - Allows a single timed weld cycle each time the gun trigger is held closed. Duration (0.2-9.9 seconds) is set by the Spot ON timer.

Digital “Memory” Voltmeter - Displays arc voltage from 0 to 80V DC, when welding gun trigger is activated, with automatic polarity indication for positive or negative electrode. The last welding voltage monitored at end of weld is displayed for 5 seconds after weld has stopped. This allows checking actual voltage after weld has stopped.

Digital “Memory” Ammeter - Weld Feed Speed (WFS) display may be selectable to display welding amps only while welding and the last welding amps monitored at the end of the weld will be displayed for 5 seconds after the weld has stopped. This allows checking actual weld current after the weld has stopped.

Power-down Save - All settings, including mode, Run-in speed, cold feed speed, crater speed, weld speed, timers, English-Metric units and acceleration are automatically saved when power is removed. This feature does not require batteries and when power is restored it will automatically return all settings to the state they were in when power was removed. However, the power source may overwrite any or all of these parameters after Power-Up Recall is complete.

* Based on a 10 minute time period (6 minutes on, and 4 minutes off).

KEYPAD SETUP AND OPERATION

Power-Down Save

Power to the Synergic 7 is supplied and controlled from the power source. The Synergic 7 automatically senses the loss of power when the power source is turned off.

Procedure settings, including mode, crater speed, cold feed speed , run-in speed, weld speed, timers and acceleration are automatically saved when power is removed. Arc Voltage setting is retained by the synergic power source. This feature does not require batteries and when power is restored it will automatically return all settings to the state they were in when power was removed. The power source may automatically overwrite any or all of these settings following power-up recall.

WARNING

ELECTRIC SHOCK can kill.

• Do not touch electrically live parts such as output terminals or internal wiring.

•

When inching with gun trigger, electrode and drive mechanism are “hot” to work and ground and could remain energized several seconds after the gun trigger is released.

• Turn OFF input power at welding power source before installation or changing drive roll and/or guide tubes.

• Welding power source must be connected to system ground per the National Electrical Code or any applicable local codes.

• Only qualified personnel should perform this installation.

OPERATION

Display Control Keys

The function select, timer/crater select, arrow keys and rotational encoders all effect the display. Pressing the function select key will cause a function to be displayed. Pressing the timer/crater select key will cause a timer or crater feed speed to be displayed. Whichever is pressed last is the one that will be displayed since they cannot be displayed simultaneously. Only one function or timer indicator light can be on at one time and therefore it always indicates what is being displayed. The arrow keys allow you to adjust the Run-in speed timer or crater speed being displayed. The encoder knobs allow rotational adjustment of weld wire feed speed and Arc Volts/Trim.

Note: If an indicator light is skipped, that parameter may not be enabled. Refer to section covering that parameter.

Function Select key enables operator to choose which function will be displayed as indicated by the appropriate light. Pressing the key causes lights to sequence (top to bottom) starting from the current indicated position. If a timer or crater speed is being displayed when the Function Select key is pressed, then the indicator light of the last function selected before the timer/crater key was chosen will come on and become the starting point for the sequencing.

Adjusting either encoder knob automatically transfers display (and indicator light) to the function being adjusted (Volts/Trim or Wire Feed Speed).

Top Light - indicates Voltmeter Function has been selected and arc voltage (in volts) will be displayed along with electrode polarity when the trigger has been pressed. When the trigger is not pressed, this will serve as a preset voltage/trim function and the preset voltage/trim will be displayed. The top light “blinks” when arc voltage is being displayed and stays lit when preset voltage/trim is displayed. The last welding voltage displayed before the weld is stopped, will continue to be displayed for 5 seconds

As shipped these models are setup for minimum rated fixed Run-In speed with display function deactivated. They may be user-selected to activate or deactivate adjustable Run-In display. (See section for selection of Run-In and resetting fixed RunIn speed).

Wire will be fed at the Run-In speed rate until arc current begins to flow. Once arc current flows, wire will be fed at the Weld speed rate. Decreasing Run-In speed below its lower limit (using the down arrow key) causes the display to read “- - -”. This indicates that the Run-In speed will be kept the same can reset a different Run-In speed simply by pressing the up arrow key.

The Run-In speed will also be the same the weld speed setting if rapid restrike welding applications are used, where the arc is restruck in a fraction of a second after the previous welding arc was stopped.

Acceleration Selection

Pressing both the “Gas Purge” key and then the function select key at the same time causes the acceleration setting to be displayed. The display will indicate “A-X” where X will be a number from 1 through 5 with 5 being the fastest acceleration. This number can be adjusted using the arrow keys. To exit this function, press any other key except the arrow key, gas purge or function select key.

Burnback Time Selection

If necessary, for higher wire feed speeds, burnback time maybe selected to prevent the electrode from sticking in the weld puddle a the end of the weld. Pressing both the Gas Purge Key then the function select key at the same time, displaying acceleration setting per above, then pressing the function key a second time, while holding gas purge pressed, displays the burnback time selection. Default is “b0" which is zero delay. Selecting “b1" through “b5" increases delay from 10 m sec to 50 m sec in 10 m sec increments. To exit this function press any other key except the arrow keys, gas purge or function select key.

Selection of English or Metric Speed Display Units

Pressing both the Gas Purge key and then timer select key at the same time causes the speed display units to toggle between IPM (no decimal point displayed) and m/m (a decimal point displayed). If the speed display units were IPM, then they will change to m/m. If the speed display units were m/m, then they will change to IPM. If the display is showing the volts/trim or one of the timers when the keys are pressed, the display will be changed to weld speed to indicate the selected speed display units.

Run-In Selection

Pressing both the Gas Purge key then the Cold Feed key at the same time causes Run-In function to toggle on or off, as indicated by the Run-In indicator light turning on or remaining off in the function select sequence.

Decrease Arrow - key decreases the setting of the parameter selected to be displayed, except Wire Feed Speed and Volts/Trim which are controlled by the encoder knobs.

Arrow Keys use the “Accelerating Digit” method for setting changes, where holding the arrow key causes setting change rate to accelerate from slow to fast. Releasing arrow key resets to slow setting change.

SYNERGIC 7 & 7H

As shipped, the Run-In function is off with a fixed setting of 50 IPM (1.27 m/min.). Therefore, the Run-In indicator light will not sequence with the function select key, but the fixed setting will still be used for actual Run-In speed.

Activation of adjustable Run-In speed using the above dual key press will permit Run-In speed to be adjusted with the arrow keys, (See Section 3.3.4), and the Run-In indicator light will return to the function key sequence. Repressing the above dual key again removes the Run-In light from the function key sequence, but replaces the fixed Run-In speed with the adjusted Run-In speed setting, until readjusted.

Pressing both the Gas Purge key then the Up Arrow key at the same time causes the WFS light to “blink” for about 3 seconds while display shows weld amps reading with electrode polarity symbol. This indicates that while welding, the display will show welding amps, indicated by “blinking” WFS indicator light, which continues for 5 seconds after the weld is stopped (memory ammeter) before returning to displaying WFS (light not “blinking”.)

Pressing both the Gas Purge and Up Arrow key again, returns WFS display to wire speed while welding.

When this option is connected to the feeder control receptacle the front panel knob controls are disabled and procedure control is transferred to the knob encoder controls of the remote, which function in the exact same manner.

NOTE: The dual procedure overlay must be present on the Power Wave power source for the Procedure Selector switch to function. If this overlay is not used, only Procedure A will be selected no matter what position the Procedure switch is in.

If using the optional K683-1 Dual Procedure Switch to select A or B along with the remote, both the front panel and remote Procedure selector switches must be set to “Gun Switch” (center) position.

Procedure Selector Switch

The toggle switch on the front panel provides selection of Procedure A or Procedure B, as set with the front panel knob controls. Rotating the knob encoder changes only the procedure selected by this switch. Also, this switch selects the A or B memory pair selected at the Power Wave power source.

Setting the toggle switch to the center “Gun Switch” position permits the Procedure A or Procedure B to be selected by the optional K683-1 Dual Procedure Switch. The K1449-1 Dual Procedure Remote Control can be used with this panel Procedure Switch in any position.

WIRE REEL LOADING – 50 AND 60 LB COILS (K303 OR K376 WIRE REEL ST AND)

ADJUSTABLE WIRE REEL BRAKE

The mount for standard 50 and 60 pound electrode coils includes a two-position brake assembly. Generally the brake should be at the inner position (nearest to the wire reel shaft) for wire feed speeds below 400 in./min (10 m/min). It should be at the outer position for the faster wire speeds often used when feeding smaller diameter electrode.

To adjust the brake position, remove the wire reel. Pull the cotter pin that holds the brake shoe to the arm, move the shoe and replace the cotter pin. Do not bend the cotter pin - it is held in place by a friction fit.

TO MOUNT A 50 OR 60 LB COIL:

1. To remove the wire reel from its shaft, grasp the spring loaded knob and pull out. This straightens the knob so it seats into the shaft when released. Remove the reel.

CAUTION

Always be sure the free end of the coil is securely held while the tie wires are being cut and until the wire is feeding through the drive rolls. Failure to do this will result in “back lashing” of the coil, which may tangle the wire. A tangled coil will not feed. It must be untangled or discarded.

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

8. Cut and remove only the tie wire holding the free

end of the coil. Insert the free end into one of the holes in the cover and secure it by bending it back. Cut and remove the remaining tie wires.

9. Replace the reel on the wire feeder. Grasp the shaft knob, pull it out and swing it across the reel hub, locking the reel in place.

FIGURE B.2 – LOADING A 50 OR 60 LB COIL.

2. Lay the reel flat on the floor. Loosen the spinner nut and remove the cover plate. See Figure B.2.

3. Place the coil of electrode on the reel so it unwinds as the reel rotates clockwise. DO NOT cut the tie wires at this time.

4. Be sure the coil is placed so the spring loaded arms will not interfere with the later removal of the coil tie wires.

5. When loading 0.030 to 0.045” electrode, be certain the coil is placed on the reel so the spring loaded arms are at the center of the slots in the cardboard coil liner. This provides the positive compression of the coil sides needed for troublefree wire feeding.

6. Put the cover plate on the reel so the four arms of the cover plate straddle and are in line with the spring loaded arms of the reel.

7. Tighten the cover as much as possible by hand. DO NOT hammer on the spinner nut arms.

2. Before cutting the tie wires, place the coil of electrode on the reel so it unwinds from the bottom as the reel rotates.

3. Tighten the spinner nut against the reel cover as much as possible by hand, using the reel cover spokes for leverage. DO NOT hammer on the spinner nut arms.

FIGURE B.3 – K1504-1 COIL REEL.

4. Cut and remove only the tie wire holding the free end of the coil. Hook the free end around the rim of the reel cover and wrap it around to secure. Cut and remove the retaining tie wires.

CAUTION

Always be sure the free end of the coil is securely held while the tie wires are being cut and until the wire is feeding through the drive rolls. Failure to do this will result in “backlash” of the coil, which may tangle the wire. A tangled coil will not feed, so it must either be untangled or discarded.

____________________________________

5. Be sure the coil is engaged with the spindle brake pin and the Release Bar and Retaining Collar “pops up” and that the collar retainers fully engage the retaining groove on the spindle.

Feeding Electrode

1) Turn the reel until the free end of the electrode is accessible. While tightly holding the electrode, cut off the bent end.

2) Straighten the first 6” (150mm) and cut off the first

1” (25mm). Insert the free end through the incoming guide tube. Press the Cold Inch key or the gun trigger and push the electrode into the drive roll. Feed the electrode through the gun. (If the electrode is not properly straightened, it may not feed or may not go into the outgoing guide tube causing a “birdnest”.)

WARNING

When feeding with the gun trigger, the electrode and drive mechanism are always “HOT” to work and ground and could remain “HOT” several seconds after the gun trigger is released.

OPERATION

Idle Roll Pressure Setting

The idle roll pressure is set at the factory, backed out three turns from full pressure on 4-roll feeders. This is an approximate setting. For small wire sizes and aluminum wire up to 9 or 10 turns out may be required to minimize “birdnesting”. The optimum idle roll pressure varies with type of wire, surface condition, lubrication, and hardness. The optimum idle roll setting can be determined as follows:

1) Release the incoming idle roll pressure arm, then press end of gun against a solid object that is electrically isolated from the welder output and press the gun trigger for several seconds.

2) If the wire “birdnests”, jams, or breaks at the drive roll, the idle roll pressure is too great. Back the pressure setting out 1/2 turn, run new wire through gun, and repeat above steps.

3) If the only result is drive roll slippage, disengage the gun locking nut, and pull the gun cable forward about 6” (150mm). There should be a slight waviness in the exposed wire. If there is no waviness, the pressure is too low. Increase the pressure setting 1/4 turn, reconnect the gun, tighten the locking nut, and repeat the above steps.

B-9

4) After the outgoing pressure is set, determine how many turns away from full pressure the setting is. Set both idle roll tensions to this setting. Engage both idle rolls before welding. In most applications, best wire feeding will occur when both idle roll pressures are set the same.

Gas Guard Regulator Setting

1) With the gas supply shut off, the Gas Guard regulator flow adjusting key should be set to maximum (full clockwise) which is rated to be 60 SCFH (28 lts/ min).

2) Adjust gas supply flow rate for a level higher than will be required, then adjust Gas Guard flow adjusting key counterclockwise to the desired gas flow rate.

OPERATION

Making a Weld

1) Use only Power Wave model “synergic” power sources.

2) Properly connect the electrode and work leads for the correct electrode polarity.

B-10

12) To stop welding, release the gun trigger and then pull the gun away from the work after the arc goes out and Postflow time, if used, is over.

13) If necessary to optimize arc starting, adjust wire

speed acceleration, and/or Run-In speed. (See the appropriate sections for adjusting procedures).

3) Use Mode Selection key to set desired operating mode. (Refer to Mode Selection section.)

4) Use Function Select and Arrow keys to set desired Run-in and encoder knob to set Weld Feed Speed. (Set for each procedure if using a Dual Procedure function). (See the appropriate sections for adjusting procedures).

5) Adjust the voltage or percent trim, if desired, (for each procedure if using a Dual Procedure function) using the encoder knob in “Volts/Trim” function (refer to Volts/Trim section). The final setting can be adjusted according to the desired arc voltage while welding.

6) Use Timer/Crater Select and Arrow keys to set desired timers, or crater speed if 4-step trigger with Crater fill has been selected. (Refer to the Timer/Crater section).

7) Feed the electrode through the gun and cable and then cut the electrode within approximately .38” (9.5mm) of the end of the contact tip for solid wire, and within approximately .75” (19mm) of the extension guide for cored wire.

8) Connect work cable to metal to be welded. Work cable must make good electrical contact to the work. The work must also be grounded as stated in “Arc Welding Safety Precautions”.

WARNING

When using an Open Arc process, it is necessary to use correct eye, head, and body protection

____________________________________

9) If used, be sure shielding gas valve is turned on.

10) Position electrode over joint. End of electrode

may be lightly touching the work.

11) Lower welding helmet, close gun trigger and start

welding. Hold the gun so the contact tip to work distance gives the correct electrical stickout as required for the procedure being used.

Wire Reel Changing

At the end of a coil, remove the last of the old electrode coil from the conductor cable by either pulling it out at the nozzle end of the gun or by using the following procedure:

1) Cut the end of the electrode off at the gun end. Do not break it off by hand because this puts a slight bend in the wire making it difficult to pull it back through the nozzle.

2) Disconnect the gun cable from the gun connector on the Synergic 7 Wire Feed Unit and lay the gun and cable out straight.

3) Using pliers to grip the wire, pull it out of the cable from the connector end.

4) After the electrode has been removed, reconnect the gun cable to the Synergic 7.

Load a new reel of electrode per the instructions in the Wire Reel Loading sections.

Wire Feed Overload Protection

The Synergic 7 has solid-state overload protection of the wire drive motor. If the wire drive motor becomes overloaded for an extended period of time, the protection circuitry turns off the power source, wire feed and solenoid and then displays H30. This indicates the wire drive motor is overloaded and the number indicates the time remaining in seconds before the unit will automatically reset. The number continues to decrement every second until it reaches 0. At that time, the unit resets automatically and the previous display will return indicating the unit is ready to operate again. Overloads can result from improper tip size, liner, drive rolls, or guide tubes, obstructions or bends in the gun cable, feeding wire that is larger than the rated capacity of the feeder or any other factors that would impede normal wire feeding. (See section on Avoiding Wire Feeder Problems.)

Grounding Lead Protector

The frame of the Synergic 7 wire feeder is grounded to the frame of the power source by a lead in the control cable. An overload protector prevents welding current from damaging this lead if the electrode circuit touches the wire feeder frame while the electrode is electrically hot.

If such a grounding lead fault occurs, the wire feeder display will show "GLP", and the trigger circuit will be disabled. To reset the circuit, release the trigger, make sure that the electrode is not touching the wire feeder frame, and then either press any key on the keypad or close the trigger. When the GLP circuit is reset, the "GLP" display is removed and the wire feeder is returned to normal operating mode.

To prolong the life of the reel shaft, periodically coat it with a thin layer of grease.

D-1

ELECTRIC SHOCK can kill.

• Do not touch electrically live parts such as output terminals or internal wiring.

•

When inching with gun trigger, electrode and drive mechanism are “hot” to work and ground and could remain energized several seconds after the gun trigger is released.

• Turn OFF input power at welding power source before installation or changing drive roll and/or guide tubes.

• Welding power source must be connected to system ground per the National Electrical Code or any applicable local codes.

• Only qualified personnel should perform this installation.

Observe all additional Safety Guidelines detailed throughout this manual.

Routine Maintenance

Drive Rolls and Guide Tubes

After feeding every coil of wire, inspect the drive roll section. Clean it as necessary. Do not use a solvent for cleaning the idle roll because it may wash the lubricant out of the bearing. The driver roll and guide tubes are stamped with the wire sizes they will feed. If a wire size other than that stamped on the roll(s) is to be used, the roll(s) and guide tubes must be changed.

The drive rolls for .035” (0.9mm) through .052” (1.3mm) cored electrode and 1/16” (1.6mm) through 3/32” (2.4mm) electrode have a double set of teeth so they can be reversed for additional life. Drive rolls for .023" (0.6 mm) through .052" (1.3 mm) solid electrodes and aluminum sizes have no teeth, but use two grooves so they also can be reversed for additional life.

No maintenance of the two-position adjustable brake is needed. If the brake shoe wears through to the metal, replace the brake assembly.

Wire Reel Mounting - Readi-Reels, 10 through 44lb (4.5-20kg) Spools and 5060lb Coils with K1504-1 Adapter

No routine maintenance required. Do not lubricate 2” (51mm) spindle.

Avoiding Wire Feeding Problems

Wire feeding problems can be avoided by observing the following gun handling procedures:

a) Do not kink or pull cable around sharp corners.

b) Keep the electrode cable as straight as possible

when welding or loading electrode through cable.

c) Do not allow dolly wheels or trucks to run over

cables.

d) Keep cable clean by following maintenance

instructions.

e) Use only clean, rust-free electrode. The Lincoln

electrodes have proper surface lubrication.

f) Replace contact tip when the arc starts to become

unstable or the contact tip end is fused or deformed.

g) Do not use excessive wire spindle brake settings.

Periodic Maintenance

Wire Drive Motor and Gearbox

See section on Wire Feed Drive Roll and Guide Tube Kits for roll changing instructions.

SYNERGIC 7 & 7H

Every year inspect the gearbox and coat the gear teeth with a moly-disulfide filled grease. Do not use graphite grease.

Every six months check the motor brushes. Replace them if they are less than 1/4” long.
