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. 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 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.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 manufacturerʼs instructions for this

equipment and the consumables to be used, including the material safety data sheet (MSDS) and follow your employerʼs safety practices. MSDS forms are available from your welding distributor or from the manufacturer.

5.f. Also see item 1.b.

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

Remember that welding sparks and hot materials from welding can easily go through small cracks and openings to adjacent areas. Avoid welding near hydraulic lines. Have a fire extinguisher readily available.

6.b. Where compressed gases are to be used at the job site, special precautions should be used to prevent hazardous situations. Refer to “Safety in Welding and Cutting” (ANSI Standard Z49.1) and the operating information for the equipment being used.

6.c. When not welding, make certain no part of the electrode circuit is touching the work or ground. Accidental contact can cause overheating and create a fire hazard.

6.d. Do not heat, cut or weld tanks, drums or containers until the proper steps have been taken to insure that such procedures will not cause flammable or toxic vapors from substances inside. They can cause an explosion even 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.

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 LʼArc

1. Protegez-vous contre la secousse électrique:

a. Les circuits à lʼélectrode 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 sʼisoler 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 lʼeau 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 sʼapplicuent aussi au pistolet de soudage.

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 nʼimporte quelle partie du corps.

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

6. Eloigner les matériaux inflammables ou les recouvrir afin de prévenir tout risque dʼincendie 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 dʼincendie.

8. Sʼassurer que la masse est connectée le plus prés possible de la zone de travail quʼil est pratique de le faire. Si on place la masse sur la charpente de la construction ou dʼautres 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 dʼincendie ou dʼechauffement des chaines et des câbles jusquʼà ce quʼils 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 dʼopérations de dégraissage, nettoyage ou pistolage. La chaleur ou les rayons de lʼarc 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.

PRÉCAUTIONS DE SÛRETÉ POUR

3. Un coup dʼarc peut être plus sévère quʼun coup de soliel, donc:

a. Utiliser un bon masque avec un verre filtrant approprié

ainsi quʼun verre blanc afin de se protéger les yeux du rayonnement de lʼarc et des projections quand on soude ou quand on regarde lʼarc.

b. Porter des vêtements convenables afin de protéger la

peau de soudeur et des aides contre le rayonnement de lʻarc.

c. Protéger lʼautre personnel travaillant à proximité au

soudage à lʼaide dʼécrans appropriés et non-inflammables.

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

LES MACHINES À SOUDER À TRANSFORMATEUR ET À REDRESSEUR

1. Relier à la terre le chassis du poste conformement au code de lʼélectricité 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, Iʼinstallation et lʼentretien du poste seront effectués par un électricien qualifié.

3. Avant de faires des travaux à lʼinterieur de poste, la debrancher à lʼinterrupteur à la boite de fusibles.

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

1) Pull open the Pressure Door.

A-2

ELECTRIC SHOCK can kill.

• Turn the input power off at the power source disconnect switch before attempting to connect the input power to the LN-10 Control.

• Only qualified personnel should perform this installation.

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

Electrode Routing

The electrode supply may be either from reels, ReadiReels, spools, or bulk packaged drums or reels. Observe the following precautions:

a) The electrode must be routed to the wire drive

unit so that the bends in the wire are at a minimum, and also that the force required to pull the wire from the reel into the wire drive unit is kept at a minimum.

b) The electrode is "hot" when the gun trigger is

pressed and must be insulated from the boom and structure.

c) If more than one wire feed unit shares the same

boom and are not sharing the some power source output stud, their wire and reels must be insulated from each other as well as insulated from their mounting structure.

WIRE DRIVE SPEED RANGE SELECTION

The rated speed and wire size range for each wire drive head is shown in the SPECIFICATIONS in the front of this section.

2) Remove the Phillips head screw retaining the pinion gear to be changed and remove the gear. If the gear is not easily accessible or difficult to remove, remove the feedplate from the gearbox. To remove feedplate:

a) Loosen the clamping collar screw using a 3/16"

Allen wrench. The clamping collar screw is accessed from the bottom of the feedplate. It is the screw which is perpendicular to the feeding direction.

b) Loosen the retaining screw, which is also

accessed from bottom of feeder, using a 3/16" Allen wrench. Continue to loosen the screw until the feedplate can be easily pulled off of the wire feeder.

3) Loosen, but do not remove, the screw on the lower right face of the feedplate with a 3/16" Allen wrench.

4) Remove the screw on the left face of the feedplate. If changing from high speed (larger gear) to low speed (smaller gear), line the lower hole on the left face of the feedplate with the threads on the clamping collar. Line the upper hole with the threads to install larger gear for high speed feeder. If feedplate does not rotate to allow holes to line up, further loosen the screw on right face of feedplate.

5) Install gear onto output shaft and secure with flat washer, lock washer, and Phillips head screw which were previously removed.

6) Tighten the screw on lower right face of feedplate.

Control Speed Range Setting

The speed range is set up to match the wire feed head connected to the LN-10 control by properly setting the switch (S1) code on the control board inside the control box. See OPERATION “Setting the DIP Switches” for setting instructions.

10 Series Wire Drive Ratio Selection

The 10 Series type drives include two external gear sizes; a 1" dia. gear and a 1-1/2" dia. gear. The smaller gear provides the low speed range ratio, and the larger gear provides the high speed range ratio per the SPECIFICATIONS in the front of this section.

The following procedure is for changing ratio of the 10 Series wire drive:

7) Re-attach feedplate to wire feeder if removed in Step 2.

8) Feedplate will be rotated out-of-position due to the gear change. To re-adjust angle of feedplate:

a) Loosen the clamping collar using a 3/16" Allen

wrench. The clamping collar screw is accessed from the bottom of the feedplate. It is the screw which is perpendicular to the feeding direction.

b) Rotate feedplate to the desired angle and tight-

1. Instead of displaying a preset value in volts, the top display will show a number from "0.00" to "10.00" in increments of 0.02. The number can be used for setting run-in "voltage" as well as "weld preset voltage". When the trigger is closed or while welding, the top display will display actual arc voltage.

The voltage displayed while welding can be used to determine the arc voltage to be expected for a given number setting. Actual arc voltage display will still flash for 5 seconds after a weld has been completed.

2. If a loss of arc voltage occurs, wire will NOT stop feeding. The Loss of Voltage Sense Shutdown feature is disabled to permit the use of the LN-10 with power source connections that do not connect the work voltage back to the LN-10 through the input power cable. The actual weld voltage while welding will NOT be shown on the top display if the work voltage is not available to the LN-10 through the input power cable.

Also, the difference between Run-in voltage and Weld voltage settings is maintained automatically if the Weld voltage setting is changed, so the run-in voltage encoder knob does not need to be changed to follow the Weld voltage setting.

When trigger is closed (and preflow time is over) the wire feeds at Run-In speed and volts until the welding arc strikes, which causes the feed speed and volts to change to Weld settings.

If the arc does not strike within about 2 seconds, the Run-In speed automatically changes to Weld speed to permit “Hot”

Security Mode

Security mode is used to capture timer, acceleration, and control selections and settings, then to disable these selections until security mode is deactivated. Encoder knob setting changes of cold feed, weld speed and weld voltage are not disabled.

Security mode is activated, or deactivated, by shutting off the input power to the LN-10 with all Timer and Control settings as desired for both procedures for both Feeders. Then setting S2 DIP switch 3 inside the LN-10 Control Box ON or OFF and restoring input power (See “Setting DIP Switches” in this section).

When activated, the Timer and Control selections no longer light, but function with the captured settings. All other keys and encoder knob controls function normally.

feeding at higher speed setting for loading wire.

Acceleration Selection

To provide optimum starting of various processes and procedures, the wire feed acceleration of the LN-10 can be set to five levels; 1 thru 5, for each feeder and procedure. 1 is the slowest acceleration and 5 is the fastest. (Factory set to 4.)

Pressing control key again, or closing the gun trigger, shuts off light indicating knob settings and displays are returned to Weld Voltage and Wire Feed Speed.

Digital “Memory” Voltmeter

When the welding gun trigger is activated, the top LN-10 display reads actual welding voltage from 0.0 to 60.0 VDC with automatic polarity indication for positive (+) or negative (-) electrode.

If actual voltage drops below 8.0 volts for over 0.8 sec when the trigger is closed, Loss of Voltage Sense Shutdown will occur. See “Loss of Voltage Sense Shutdown” in this section.

The last welding voltage monitored at the end of the weld is displayed for 5 seconds after the weld has stopped, as indicated by a 5 second “blinking” display. This allows checking actual weld voltage after weld has stopped.

Any keypad or trigger operation will interrupt the 5 second memory display.

Maximum and Minimum Limits Setting Modes

Limits setting modes are available for limiting the range for setting wire feed speed and voltage. The limits can be set independently for each procedure. The following steps should be followed for setting the maximum and minimum limits:

1. Turn off the power at the power source.

2. Remove the two screws at the top of the LN-10 control box and open the control box door.

3. Put DIP switch S2 switch 5 in the ON position.

4. Close the control box door.

5. Turn on the power at the power source.

6. Set the maximum WFS and voltage limits for procedure A and procedure B using the two encoder knobs and the procedure key. The maximum WFS limit can be set for the entire range of the wire drive that is being used. The maximum voltage limit can be set over the range of 10.0 to 60.0 volts. The maximum limits can be turned off independently for each procedure by turning the encoder knobs clockwise until the appropriate display (WFS or voltage) reads “OFF” while the correct procedure light is lit. (The limits are set to “OFF” from the factory.

7. Turn off the power at the power source.

8. Open the control box door.

9. Put DIP switch S2 switch 5 in the OFF position and DIP switch S2 switch 6 in the ON position.

10. Close the control box door.

11. Turn on the power at the power source.

12. Set the minimum WFS and voltage limits for pro-

cedure A and procedure B using the two encoder knobs and the procedure key. The minimum WFS limit can be set from the minimum speed of the wire drive that is being used to the maximum limit that has been set for the selected procedure. The minimum voltage limit can be set over the range of

10.0 to the maximum voltage limit that has been set for the selected procedure. The minimum limits can be turned off independently for each procedure by turning the encoder knobs counter clockwise until the appropriate display (WFS or voltage reads “OFF” while the correct procedure light is lit. (The limits are set to “OFF” from the factory).

WIRE REEL LOADING - READI-REELS, SPOOLS OR COILS

To Mount a 30 Lb. (14 kg) Readi-Reel Package (Using the Molded Plastic K363-P Readi-Reel Adapter:)

WARNING

Check to be sure the Retaining Spring has fully returned to the locking position and has SECURELY locked the Readi-Reel Cage in place. Retaining Spring must rest on the cage, not the welding electrode.

___________________________________________

9) To remove Readi-Reel from Adapter, depress retaining spring tab with thumb while pulling the Readi-Reel cage from the molded adapter with both hands. Do not remove adapter from spindle.

The Spindle should be located in the LOWER mounting hole.

1) Depress the Release Bar on the Retaining Collar and remove it from the spindle.

2) Place the Adapter on the spindle.

3) Re-install the Retaining Collar. Make sure that the Release Bar “pops up” and that the collar retainers fully engage the retaining groove on the spindle.

4) Rotate the spindle and adapter so the retaining spring is at the 12 o'clock position.

5) Position the Readi-Reel so that it will rotate in a direction when feeding so as to be de-reeled from bottom of the coil.

6) Set one of the Readi-Reel inside cage wires on the slot in the retaining spring tab.

7) Lower the Readi-Reel to depress the retaining spring and align the other inside cage wires with the grooves in the molded adapter.

8) Slide cage all the way onto the adapter until the retaining spring "pops up" fully.

To Mount a 50-60 Lb. (22.7-27.2 kg) Coil: (Using K1504-1 Coil Reel) (For 50-60 lb Readi-

Reels a K438 Readi-Reel Adapter must be used).

The Spindle must be located in the UPPER mounting hole.

1) With the K1504-1 Coil Reel mounted on to the 2" (51 mm) spindle (or with reel laying flat on the floor) loosen the spinner nut and remove the reel cover. (See Figure B.2).

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.

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 secure it by wrapping it around. Cut and remove the remaining 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 “backlashing” 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 reel is engaged with the spindle brake pin and the Release Bar on the Retaining Collar “pops up” and that the collar retainers fully engage the retaining groove on the spindle.

SPINNER NUT

COVER PLATE

FEEDING ELECTRODE AND BRAKE ADJUSTMENT

1) Turn the Reel or spool until the free end of the electrode is accessible.

2) While tightly holding the electrode, cut off the bent end and straighten the first 6" (150 mm). Cut off the first 1" (25 mm). (If the electrode is not properly straightened, it may not feed or may jam causing a "birdnest".)

3) Insert the free end through the incoming guide tube.

4) Press the Cold Inch key or the Cold Feed Mode gun trigger and push the electrode into the drive roll.

WARNING

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

___________________________________________

5) Feed the electrode through the gun.

6) Adjust the brake tension with the thumbscrew on the spindle hub, until the reel turns freely but with little or no overrun when wire feeding is stopped. Do not overtighten.

DRIVE ROLL PRESSURE SETTING

The LN-10 pressure is factory pre-set to about position “2" as shown on the pressure indicator on the front of the feedplate door. This is an approximate setting.

REEL

The optimum drive roll pressure varies with type of wire, surface condition, lubrication, and hardness. Too much pressure could cause “birdnesting”, but too little pressure could cause wire feed slippage with load and/or acceleration. The optimum drive roll setting can be determined as follows:

LN-10

Page 24

B-11

1) 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 drive 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, pull the gun cable forward about 6" (150 mm). There should be a slight waviness in the exposed wire. If there is no waviness, the pressure is too low. Increase the pressure setting turn, reconnect the gun, tighten locking clamp and repeat the above steps.

OPERATION

PROCEDURE FOR SETTING ANGLE OF FEEDPLATE

1) Loosen the clamping collar screw using a 3/16"

Allen wrench. The clamping collar screw is accessed from the bottom of the feedplate. It is the screw which is perpendicular to the feeding direction.

B-11

4) Use Control Select and encoder knobs to set desired Weld feed speed and voltage then Run-in speed and voltage to optimize arc starting. (Set for each procedure if using front panel, remote control or optional dual procedure switch.) (Refer to “Operation Keys” and “Display Control Keys” in this section)

5) Adjust the wire feed acceleration if desired, for each feeder and procedure. (Refer to “Acceleration Selection” in this section)

6) Use Timer Select and Voltage Encoder knob to set desired timers. (Refer to “Trigger Mode Selection” in this section)

7) Feed the electrode through the gun and cable and then cut the electrode within approximately .38" (9.5 mm) 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".

2) Rotate feedplate to the desired angle and tighten clamping collar screw.

GAS GUARD REGULATOR SETTING

NOTE: Gas supply pressure must be regulated to a

maximum of 80 psi(5.5 bar).

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 l/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.

MAKING A WELD

1) Use only a Lincoln Electric recommended constant voltage DC power source compatible with the LN10 Wire Feeder.

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

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.

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, readjust wire speed acceleration, (Refer to “Acceleration Selection” in this section) and/or Run-In speed, (Refer to “Display Control Keys” in this section).

3) Use the Mode Selection key to set desired trigger mode for each procedure. (Refer to “Trigger Mode Selection” in this section)

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 LN-10 wire drive 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 drive. Load a new reel of electrode per the instructions in “Wire Reel Loading” in this section.

LOSS OF VOLTAGE SENSE SHUTDOWN

If the actual displayed voltage, when the trigger is closed, drops below 8.0 volts for over 0.8 second it is assumed the voltage feed back sensing circuit to the LN-10 is opened or faulty, so Loss of Voltage Sense Shutdown occurs until the trigger is released.

This shutdown stops the motor, shuts off the gas flow and disables the power source output to prevent the LN-10 voltage control from driving the power source output too high due to loss of proper feedback sensing via #21 (WORK) and #67 (ELECTRODE) sensing leads.

WIRE FEED OVERLOAD PROTECTION

The LN-10 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 gas solenoid, and then displays “H30” on the WFS display (with blank Voltage display). This indicates the wire drive motor is overloaded and will remain shut down for about 30 seconds before the unit will automatically reset. The “H30” display decrements every second until it reaches “H00”. At that time, the unit resets automatically and the previous displays 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 “Avoiding Wire Feeding Problems” in the MAINTENANCE section).

GROUNDING LEAD PROTECTOR

The frame of the LN-10 Control 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 WFS display will show “GLP,” (with blank Voltage display) 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.

USING DUAL PROCEDURE WITH FAST-MATE GUNS

There are a number of different options available for using dual procedure with Fast-Mate guns. These configurations are outlined below along with any additional required equipment.

Using Dual Schedule with Fast-Mate Guns on -10 Series Feeders

Configuration 1

K489-9 Dual Schedule Fast-Mate adapter K575-Magnum 400 DS/FM gun (or competitive

DS/FM gun)

K1557-1 SWIVEL MOUNT

The K1557-1 Swivel mount attaches to the power source. This kit includes a feeder adapter plate that allows the feeder to rotate on top of the power source. The feeder can be easily separated from the swivel mount at any time. This option is compatible with the K1556-1 Light Duty Caster Kit.

K1556-1 LIGHT DUTY CASTER KIT

This option provides 4 casters and all required hardware to mount it to the Power Feed 10. This option is compatible with the K1557-1 Swivel Mount.

K* Non-DS Fast-Mate gun (Magnum 450WC,

Magnum 200, Magnum 300, Magnum 400, and others)

K1558-1 REMOTE SWITCH INTERFACE MODULE

The Module provides for user interface connection of an external switch (flow switch, etc.) which must be closed to enable the feeder welding operation. Also, the Module provides for interface connection of external equipment (fume extractor, etc.) to the Moduleʼs isolated relay contacts which actuate when the feeder welding gas solenoid is activated (representing welding operation in process).

K1561-1 ROBOTICS INTERFACE MODULE

The module plugs directly into the LN-10 control board and provides an interface to a properly equipped Fanuc robot. When installed and properly configured, the K1561-1 Robotics Interface Module allows complete control of the welding process from the robot controller. The Lincoln Electric Companyʼs Automation Center should be contacted for questions regarding installation or operation of the Robotics Interface Module.

K1634-3 WIRE REEL ENCLOSURE KIT

The K1634-3 Wire Reel Enclosure Kit provides the necessary parts to cover the wire and protect it from excessive dirt and contamination. The kit is not for use with 60lb coils (most 30 lb, 15kg, 44 lb fiber spools, and smaller coils will work). The kit includes a 2 part plastic reel cover, a Magnum conduit adapter for the incoming end of the wire feeder feed plate, and a short length of Magnum conduit to go between the reel cover and the feedplate.

D-1 SAFETY PRECAUTIONS

MAINTENANCE

AVOIDING WIRE FEEDING PROBLEMS

D-1

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.

Observe all additional Safety Guidelines detailed throughout this manual.

ROUTINE MAINTENANCE

Drive Rolls and Guide Tubes

Wire feeding problems can be avoided by observing the following gun handling and feeder set up procedures:

• Do not kink or pull cable around sharp corners.

• Keep the electrode cable as straight as possible when welding or loading electrode through cable.

• Do not allow dolly wheels or trucks to run over cables.

• Keep cable clean by following maintenance instructions.

• Use only clean, rust-free electrode. The Lincoln electrodes have proper surface lubrication.

• Replace contact tip when the arc starts to become unstable or the contact tip end is fused or deformed.

• Do not use excessive wire spindle brake settings.

• Use proper drive rolls, guide tubes and drive roll pressure settings.

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.

See “Procedure to Install Drive Roll and Guide Tubes” in the INSTALLATION section for roll changing instructions.

WIRE REEL MOUNTING - READI-REELS AND 10LB THROUGH 30LB (4.5-14KG) SPOOLS

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

PERIODIC MAINTENANCE

Wire Drive Motor and Gearbox

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.

Gun and Cable Maintenance

See appropriate Operatorʼs Manual.

PROCEDURE FOR REMOVING FEEDPLATE FROM WIRE FEEDER

1) Loosen the clamping collar screw using a 3/16" Allen wrench. The clamping collar screw is accessed from the bottom of the feedplate. It is the screw which is perpendicular to the feeding direction.

2) Loosen the retaining screw, which is also accessed from bottom of feeder, using a 3/16" Allen wrench. Continue to loosen the screw until the feedplate can be easily pulled off of the wire feeder.
