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 ventthe 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 fumeshave 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 engineis 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 arenow 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 tapewhen 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. Ifthe electrode cable is on your right side, the work cable should also be on your right side.

___________________________________________________

1.g. To prevent accidentally starting gasolineengines while turning the engine or welding generator during maintenance work, disconnect the spark plug wires, distributor cap or magneto wire asappropriate.

2.d.4. Connect the work cable to the workpiece as close as possible to thearea being welded.

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

SAFETY

ELE CTRIC SHOC K 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-f ree

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 mu s t be pe r for m ed un d er el e ctr i cal l y haz a rdou s con ditions (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, elect rode reel, weldin g head, n ozzle or semiauto matic welding gun are also electrically “hot”.

3.d. Always be sure the work cable makes a good electrical connection with the metal being welded. The connection should be as close as possible to the area being welded.

3.e. Ground the work or metal to be welded to a good electrical (earth) ground.

3.f.

Maintain the electrode holder, work clamp, welding cable and welding machine in good, safe operating condition. Replace damaged insulation.

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

3.h. Never simultan eo usly t ouch e lectric al ly “ ho t” p ar ts o f 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.

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 prod uce fumes and gases hazardous to health. Avoid breathing these fumes and gas es. 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

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 isolerles 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 desgrilles metalliques, principalement dans les positions assis ou couché pour lesquelles une grande partie du corpspeut 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 latension 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.

6. Eloigner les matériaux inflammables ou les recouvrir afin de prévenir tout risqued’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 unrisque 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 cequ’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 fumeéstoxiques.

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 produitsirritants.

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

2. Dans lecas de travail au dessus du niveau du sol, seprotéger 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 regardel’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’aided’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.

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

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 àla terre.

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

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

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

PRODUCT DESCRIPTION

The K316L-[ ] / LN™-23P is a lightweight, portable wire feed unit which includes calibrated wire speed control, voltage control, wire drive with enclosed 14 lb. wire reel, analog voltmeter and various input control and electrode cable lengths.

The LN™-23P was designed specifically for Innershield pipe welding, but, with the proper electrode, can be utilized for general purpose welding.

The feeder is designed for welding with 14 pound coils of .068 and 5/64 Innershield self-shielding electrodes using a constant voltage (CV) type DC power Source. When shipped, it is internally connected for welding with electrode negative polarity (DC–). Depending upon which gun and cable is used, its rating is either 350 amps or 250 amps at 60% duty cycle.

The wire speed control has a calibrated dial plate with a range of 30 to 170 inches per minute which allows quick and easy setting of the required wire feed speed. The wire speed is not affected by changes in the arc voltage setting even though the wire feed circuit is powered by arc voltage. A two-position switch, mounted on the gun provides a reduced speed circuit. This allows selection of either the preset wire speed or 83% of the preset speed.

A low voltage gun trigger circuit turns both the power source output and wire feed on and off. The gun trigger circuit is interlocked by a weld current sensing reed switch so that while welding, the gun trigger switch does not have to be held closed. The welding process is stopped by pulling the gun away from the work. The electrode remains cold until the gun trigger is operated again.

LOADING THE WIRE REEL

(For machines that have code numbers Lower than 11383.)

• Lay the LN™-23P flat with the wire reel cover up, unclip the rubber retaining strap, and remove the cover.

• Remove the center clamping nut and the cover plate from the wire reel.

• Unpack the 14-pound coil of wire. Be sure not to bend the side tangs of the coil liner and straighten any tangs that may have been bent.

• Place the coil on the wire reel so the coil will unwind when it rotates in a clockwise direction.

• Remove the start end of the coil from its holding slot in the coil liner, cut off the bent end, straighten the first few inches and thread it through the wire feed conduit connected to the wire enclosure until several inches of electrode are exposed. Be careful not to release the electrode until it is through the wire feed conduit; otherwise, it will unwind and tangle.

• Be sure all the lower tangs of the coil liner are flush against the back half of the wire reel and that none of the upper tangs are bent in against the coil.

• Replace the reel cover plate and the center clamping nut.

• Replace the cover of the wire reel enclosure and clip the retaining strap in place.

• Pull about 2 feet of the exposed end of the electrode through the wire feed conduit. Slide the insulator all the way up on the wire feed conduit. Make a single, free loop in the electrode and feed the end into the section of wire feed conduit connected to the gearbox. Press the gun trigger and push the electrode into the drive rolls. Release the electrode as soon as it is picked up by the drive rolls. Continue feeding electrode until the excess length is fed through the drive rolls. Watch the single loop and guide it if necessary to make certain it untwists without kinking. Do not feed electrode through the gun cable at this time. Slide the insulator down on wire feed conduit until it slips over section of conduit connected to gearbox.

• Set the unit upright on floor, straighten the gun cable, press the gun trigger, and feed electrode though the gun and cable assembly.

OPERATION

DRIVE ROLL PRESSURE

The drive roll pressure is pre-set at the factory for proper feeding. If the idle roll tension must be relieved temporarily, see the Maintenance Section for proper adjustment procedure.

ADJUSTING WIRE FEED SPEED AND VOLTAGE

Set the wire feed as specified in the procedures using the calibrated dial on the back of the LN™-23P control box. When the reduced wire speed switch (mounted on the gun handle) is in Position No. 1, the wire feed speed will be that which is indicated on the dial. In Position No. 2, the wire feed speed will be 83% of the figure indicated on the dial.

Set the voltage by adjusting the voltage control while welding until the voltage specified in the procedures is indicated on the meter. The meter reading with the power source on but not welding is the open circuit voltage. With some power sources, this voltage may be significantly higher than welding voltage.

When establishing initial procedures, start with the voltage control set near minimum. Strike an arc on scrap steel. If the electrode gets hot but the arc fails to start, increase the voltage settings until the arc can be established.

For older Code units (9805), never set the power source open circuit voltage higher than 50 LN™-23P will not feed wire if the voltage is higher than 50 CV Converter or a DC-600 and inching wire (not welding) at open circuit voltages below 20 volts or above 25 volts, feeding may be unsteady or the wire speed may vary from that set on the dial. This condition does not exist while welding. Minimum usable arc voltage is 14 volts.

Loosen the insulated socket head screw on the side of the gun, rotate the gun nozzle to the position most convenient for the particular application, and retighten the screw.

When welding, set the wire feeder on the floor or hang it near the work area as convenient. Place the LN™23P to minimize the amount of spatter falling onto it.

Always keep the gun cable as straight as practical and avoid sharp bends.

Be sure the electrode cable, work cable, and control lead are connected and the power source is on.

Press the gun trigger to feed the electrode out of the gun. Use a visible stickout equal to the electrical stickout specified in the procedures for the wire being used.

Position the gun with the wire just off or lightly touching the work. Press the gun trigger to start the arc. Once the arc is established, the gun trigger can be released while welding. The gun trigger interlock circuit automatically keeps the welding process on. At the end of the weld, pull the gun away from the work.

When not welding, always store the gun in the insulated tube on the front of wire feeder.

While welding with one feeder of a two-feeder installation the electrode of the second feeder is “HOT”. Only one feeder at a time can be used for welding. Do not press the gun trigger of the idle feeder while the other feeder is being used since this can shut down the feeder being used for welding.

NOTE: For improved readability of the voltmeter in some applications, the voltmeter guard may be installed rotated end for end. This will result in the protective bars crossing the meter face in a different location.

MAKING THE WELD

Be sure the proper contact tip for either .068" or 5/64" wire, as appropriate, is in the gun. The thread protector should cover the external threads on the nozzle.

GUN AND CABLE MAINTENANCE

Remove spatter from tip after each ten minutes of arc time or as required.

Replace worn contact tips and thread protectors as required.

Replace worn spring liners in nozzles. The life of the spring can be doubled by rotating it 180°.

Clean cables after using approximately 300 pounds of electrode. Remove the cable from the wire feeder and lay it out straight on the floor. Remove the contact nozzle tip from the gun. Using an air hose and only partial pressure, gently blow out the cable from the gun end. (Too much pressure at the start will cause the dirt to form a plug.) Flex the cable over its entire length and again blow out the cable. Repeat this procedure until no further dirt comes out.

REPLACING OR REVERSING DRIVE ROLLS (See

Figure D.1). Loosen idle roll tension screw (Item 1) to release pres-

sure between idle roll and drive rolls. Remove hex head screw (Item 2) with a 1/2" wrench

and remove the drive roll clamping collar (Item 3). Remove drive rolls from shaft.

Wipe the drive roll surfaces clean. Then install new drive rolls. If reversing drive rolls, turn drive rolls over so unworn teeth face each other.

Replace clamping collar and hex head screw. Tighten the idle roll tension screw until it bottoms and

then back it out two complete turns. If feeding problems persist, do not increase the tension. check for other issues such as the wire spool binding or a dirty or damaged gun cable

REMOVING IDLE ROLL ASSEMBLY

Remove the idle roll tension screw (Item 1), tension spring retainer (Item 4), and tension spring (Item 5).

Before any gun is disassembled, remove unit from the wire feeder or shut off the power source.

WIRE DRIVE ASSEMBLY MAINTENANCE

Every 500 pound s of electrode, the drive roll section should be inspected and cleaned out if necessary. Do not use a solvent for cleaning the idle roll as it may wash lubricant out of the bearing.

Replace drive rolls as required. Drive rolls should be worn on both sides before replacing. See “A” of this section.

Pivot the idle roll assembly away from the gearbox and lift it off the pivot pin (Item 6).

To re-assemble, replace idle roll assembly, tension spring, retainer, and tension screw. Adjust the tension screw as described above.
