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.

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.

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

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.
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.
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.
PRÉCAUTIONS DE SÛRETÉ POUR
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.
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.

CAUTION
Be certain that the cylinder valve is CLOSED before attempting to attach the fuel supply hose coupler to the cylinder. Connect the coupler to the fuel cylinder and tighten by hand.
___________________________________________
After connecting the fuel supply to the supply cylinder, open the valve on the fuel cylinder and leak test by brushing a 50/50 soap and water solution on to the fol­lowing connections:
• Both ends of the fuel hose where it enters the metal connector.
• The threaded fitting on the end of fuel hose attached to the Ranger 250 LPG fuel shut off solenoid.
• The fuel hose coupler and the connection to the cylinder valve.
• The stem of the cylinder valve and where the valve is attached to the top of the cylinder.
• All other fittings on top of the fuel cylinder.
If growing bubbles appear, there is a leak. Re-tighten connection or replace defective component. Retest to make sure that there is no leak.
Leak test must be performed each time the fuel cylin­der is replaced.
Always close the cylinder valve when the machine is not being used.

OIL
The RANGER 250 LPG is shipped with the engine crankcase filled with high quality SAE 10W-30 oil. Check the oil level before starting the engine. If it is not up to the full mark on the dip stick, add oil as required. Check the oil level every four hours of run­ning time during the first 25 running hours. Refer to the engine Operator’s Manual for specific oil recom­mendations and break-in information. The oil change interval is dependent on the quality of the oil and the operating environment. Refer to the Engine Operator’s Manual for the proper service and maintenance inter-
vals.
ENGINE COOLING SYSTEM
Air to cool the engine is drawn in lower set of louvers on the case back. It is important that the intake air is not restricted. Allow a minimum clearance of 2 feet (0.6m) from the case back to a vertical surface.
BATTERY CONNECTION
CAUTION
Use caution as the electrolyte is a strong acid that can burn skin and damage eyes.
------------------------------------------------------------------------
The RANGER 250 LPG is shipped with the negative battery cable disconnected. Make certain that the RUN-STOP switch is in the STOP position. Remove the two screws from the rear battery tray using a screwdriver or a 3/8" socket. Attach the negative bat­tery cable to the negative battery terminal and tighten using a 1/2" socket or wrench.
NOTE: This machine is furnished with a wet charged battery; if unused for several months, the battery may require a booster charge. Be careful to charge the bat­tery with the correct polarity.

------------------------------------------------------------------------
HIGH FREQUENCY GENERATORS FOR TIG APPLICA TIONS
The K930-2 TIG Module is suitable for use with the RANGER 250 LPG. The RANGER 250 LPG and any high frequency generating equipment must be proper­ly grounded. See the K930-2 Operating Manual for completed instructions on installation, operation, and maintenance.
REMOTE CONTROL
The RANGER 250 LPG is equipped with a 6 pin and a 14-pin connector. The 6-pin connector is for connect­ing the K857 or K857-1 Remote Control (optional) or for TIG welding, the K870 foot Amptrol or the K963-3 hand Amptrol.
When in the CC-STICK, DOWNHILL PIPE, and CV­WIRE modes or when a remote control is connected to the 6-pin connector, the auto-sensing circuit in the RANGER 250 LPG automatically switches the OUT­PUT control from control at the welder to remote con­trol .
The 14-pin connector is used to directly connect a wire feeder or TIG Module (K930-2) control cable. In the CV-WIRE mode, the RANGER 250 LPG auto­sensing circuit automatically makes the RANGER 250 LPG Output Control inactive and the remote voltage control active when the control cable is connected to the 14 pin connector.
When in the TOUCH START TIG mode and when a Amptrol is connected to the 6 Pin connector the OUT­PUT dial is used to set the maximum current range of the CURRENT CONTROL of the Amptrol.
NOTE: When a wire feeder with a built in welding volt­age control is connected to the 14 pin connector, do not connect anything to the 6 pin connector.
SP ARK ARRESTER
Some federal, state or local laws may require that gasoline or diesel engines be equipped with exhaust spark arresters when they are operated in certain locations where unarrested sparks may present a fire hazard. The standard muffler included with this welder does not qualify as a spark arrester. When required by local regulations, a suitable spark arrester, such as the S24647 must be installed and properly main­tained.

MACHINE GROUNDING
Because this portable engine driven welder creates its own power, it is not necessary to connect its frame to an earth ground, unless the machine is connected to premises wiring (home, shop, etc.)
To prevent dangerous electric shock, other equipment to which this engine driven welder supplies power must:
1) Be grounded to the frame of the welder using a grounded type plug.
2) Be double insulated.
WARNING
Do not ground the machine to a pipe that carries explosive or combustible material.
------------------------------------------------------------------------
When this welder is mounted on a truck or trailer, its frame must be electrically bonded to the metal frame of the vehicle. Use a #8 or larger copper wire connect­ed between the machine grounding stud and the frame of the vehicle. When this engine driven welder is connected to premises wiring such as that in a home or shop, its frame must be connected to the system earth ground. See further connection instruc­tions in the section entitled "Standby Power Connections" as well as the article on grounding in the latest U.S. National Electrical Code and the local code.
In general, if the machine is to be grounded, it should be connected with a #8 or larger copper wire to a solid earth ground such as a metal water pipe going into the ground for at least ten feet and having no insulat­ed joints, or to the metal framework of a building which has been effectively grounded. The U.S. National Electrical Code lists a number of alternate means of grounding electrical equipment. A machine grounding stud marked with the symbol
is provided on the front of the welder.
WELDING TERMINALS
WELDING OUTPUT CABLES
With the engine off connect the electrode and work cables to the output studs. The welding process dic­tates the polarity of the electrode cable. These con­nections should be checked periodically and tightened with a 3/4" wrench.
Table A.1 lists recommended cable sizes and lengths for rated current and duty cycle. Length refers to the distance from the welder to the work and back to the welder. Cable diameters are increased for long cable lengths to reduce voltage drops.

CABLE INSTALLATION
Install the welding cables to your RANGER 250 LPG as follows.
1. The engine must be OFF to install welding cables.
2. Remove the flanged nuts from the output terminals.
3. Connect the electrode holder and work cables to the weld output terminals. The terminals are identi­fied on the case front.
4. Tighten the flanged nuts securely.
5. Be certain that the metal piece you are welding (the “work”) is properly connected to the work clamp and cable.
6. Check and tighten the connections periodically.
• Loose connections will cause the output terminals to overheat. The terminals may eventually melt.

AUXILIARY POWER RECEPTACLES
Start the engine and set the “IDLER” control switch to the “High Idle” mode. Voltage is now correct at the receptacles for auxiliary power. This must be done before a tripped GFCI receptacle can be reset proper­ly. See the MAINTENANCE section for detailed infor­mation on testing and resetting the GFCI receptacle.
The auxiliary power of the RANGER 250 LPG con­sists of two 20 Amp-120 VAC (5-20R)GFCI duplex receptacles and one 50 Amp 120/240 VAC (14-50R) receptacle. The 240 VAC receptacle can be split for single phase 120 VAC operation.
The auxiliary power capacity is 9,000 Watts Peak, 8000 Watts Continuous of 60 Hz, single phase power. The auxiliary power capacity rating in watts is equiva­lent to volt-amperes at unity power factor. The max permissible current of the 240 VAC output is 33 Amps. The 240 VAC output can be split to provide two sepa­rate 120 VAC outputs with a max permissible current of 33 Amps per output to two separate 120 VAC branch circuits (these circuits cannot be paralleled). Output voltage is within ± 10% at all loads up to rated capacity. All auxiliary power is protected by circuit breakers.
2. Take necessary steps to assure load is limited to
the capacity of the RANGER 250 LPG by installing a 40 amp, 240 VAC double pole circuit breaker. Maximum rated load for each leg of the 240 VAC auxiliary is 33 amperes.
Loading above the rated output will reduce output voltage below the allowable - 10% of rated voltage which may damage appliances or other motor-dri­ven equipment and may result in overheating of the RANGER 250 LPG engine and/or alternator wind­ings.
3. Install a 50 amp, 120/240 VAC plug (NEMA Type
14-50) to the double-pole circuit breaker using No. 6, 4 conductor cable of the desired length. (The 50 amp, 120/240 VAC plug is available in the optional K802R plug kit or as part number T12153-9.)
4. Plug this cable into the 50 Amp, 120/240 Volt
receptacle on the RANGER 250 LPG case front.
The 120V auxiliary power receptacles should only be used with three wire grounded type plugs or approved double insulated tools with two wire plugs. The current rating of any plug used with the system must be at least equal to the current capacity of the associated receptacle.
NOTE: The 240V receptacle has two 120V circuits, but are of opposite polarities and cannot be paralleled.
STANDBY POWER CONNECTIONS
The RANGER 250 LPG is suitable for temporary, standby or emergency power using the engine manu­facturer’s recommended maintenance schedule.
The RANGER 250 LPG can be permanently installed as a standby power unit for 240 VAC, 3 wire, single phase, 33 amp service. Connections must be made by a licensed electrician who can determine how the 120/240 VAC power can be adapted to the particular installation and comply with all applicable electrical codes.
1. Install the double-pole, double-throw switch between the power company meter and the premis­es disconnect. Switch rating must be the same or greater than the customer’s premises disconnect and service over current protection.
