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.

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

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.

SAFETY PRECAUTIONS
WARNING
OPERATION
The LN™-23P voltage control is used to adjust the power source output. Also included is an analog voltmeter which allows easy setting of the arc voltage at the LN™-23P once the arc is established.
B-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.

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.
