Learning safety through personal experience, like a child touching a hot stove is harmful, wasteful, and un- wise. Let the experience of others teach you. Safe practices developed from experience in the use of welding and cutting are described in this manual. Research, development, and field experience have evolved reliable equipment and safe installation, opera- tion, and servicing practices. Accidents occur when equipment is improperly used or maintained. The reason for the safe practices may not always be given. Some are based on common sense, others may require technical volumes to explain. It is wiser to follow the rules. Read and understand these safe practices before at- tempting to install, operate, or service the equipment, Comply with these procedures as applicable to the par- ticular equipment used and their instruction manuals, for personal safety and for the safety of others. Failure to observe these safe practices may cause serious injury or death. When safety becomes a habit, the equipment can be used with confidence. These safe practices are divided into two Sections: 1 - General Precautions, common to arc welding and cutting; and 2 - Arc Welding {and Cutting) (only). Reference standards: Published Standards on safety are also available for additional and more complete pro- cedures than those given in this manual. They are listed in the Standards index in this manual. ANSI 249.1 is the most complete, The National Electrical Code, Occupational Safety and Health Administration, local industrial codes, and local inspection requirements also provide a basis for equip- ment installation, use, and service. 1-2. GENERAL PRECAUTIONS Different arc welding processes, electrode alloys, and fiuxes can produce differant fumes, gases, and radiation levels. In addition to the information in this manual, be sure to consult flux and elec- trode manufacturers for specific technical data and precautionary measures concerning their material. A. Burn Prevention Wear protective clothing - gauntlet gloves designed for use in welding, hat, and high safety-toe shoes. Button shirt coliar and pocket flaps, and wear cuffless trousers to avoid entry of sparks and slag. Wear helmet with safety goggles or glasses with side shields underneath, appropriate filter lenses or plates (protected by clear cover glass). This is a MUST for welding or cutting, (and chipping) to protect the eyes from radiant energy and flying metal. Replace cover glass when broken, pitted, or spattered. See 1-3A.2. Avoid oily or greasy clothing. A spark may ignite them. Hot metal such as electrode stubs and workpieces should never be handled without gloves. Medical first aid and eye treatment. First aid facilities and a qualified first aid person should be available for each shift unless medical facilities are close by for im- mediate treatment of fiash burns of the eyes and skin burns. Ear piugs shouid be worn when working on overhead or in a confined space. A hard hat should be worn when others work overhead. Flammable hair preparations should not be used by per- sons intending to weld or cut. B. Toxic Fume Prevention Severe discomfort, iilness or death can result from fumes, vapors, heat, or oxygen enrichment or depletion that welding (or cutting) may produce. Prevent them with adequate ventilation as described in ANSI Stan- dard 249.1 listed 1 in Standards index. NEVER ventilate with oxygen. Lead -, cadmium -, zinc -, mercury -, and beryilium - bearing and similar materials, when welded {or cut} may produce harmful concentrations of toxic fumes. Ade- quate local exhaust ventilation must be used, or each person in the area as well as the operator must wear an air-supplied respirator. For beryllium, both must be us- ed, Metals coated with or containing materials that emit toxic fumes shouid not be heated unless coating is removed from the work surface, the area is weli ven- tilated, or the operator wears an air-suppiied respirator. Work in a confined space only while it is being ven- tilated and, if necessary, while wearing an air-supplied raspirator. Gas leaks in a confined space should be avoided. Leaked gas in large quantities can change oxygen con- centration dangerously. Do not bring gas cylinders into a confined space. Leaving confined space, shut OFF gas supply at source to prevent possible accumulation of gases in the space if downstream valves have been accidently opened or left open. Check to be sure that the space is safe before re-entering it. Vapors from chlorinated solvents can be decomposed by the heat of the arc (or flame) to form PHOSGENE, a OM-412 Page 1 highly toxic gas, and other lung and eye irritating pro- ducts. The uitraviolet (radiant) energy of the arc can also decompose trichioroethylene and per- chloroethylene vapors to form phosgene. DO NOT WELD or cut where solvent vapors can be drawn into the welding or cutting atmosphere or where the radiant energy can penetrate to atmospheres containing even minute amounts of trichloroethylene or per- chloroethylene. - C. Fire and Explosion Prevention Causes of fire and explosion are: combustibles reached by the arc, flame, flying sparks, hot slag or heated material; misuse of compressed gases and cylinders; and short circuits. BE AWARE THAT flying sparks or falling slag can pass through cracks, along pipes, through windows or doors, and through wall or floor openings, out of sight of the goggled operator. Sparks and slag can fly 35 feet. To prevent fires and explosion: Keep equipment clean and operable, free of oil, grease, and (in electrical parts) of metallic particles that can cause short circuits. if combustibles are in area, do NOT weld or cut. Move the work if practicable, to an area free of combustibles. Avoid paint spray rooms, dip tanks, storage areas, ven- tilators. If the work cannot be moved, move com- bustibles at least 35 feet away out of reach of sparks and heat; or protect against ignition with suitable and snug-fitting, fire-resistant covers or shields. Walls touching combustibles on opposite sides should not be welded on {or cut). Walls, ceilings, and floor near work should be protected by heat-resistant covers or shields. Fire watcher must be standing by with suitable fire ex- tinguishing equipment during and for some time after welding or cutting if: a. appreciable combustibles {including building construction) are within 35 feet b. appreciable combustibles are further than 35 feet but can be ignited by sparks c. openings {concealed or visible) in floors or walls within 35 feet may expose com- bustibles to sparks d. combustibies adjacent to walls, ceilings, roofs, or metal partitions can be ignited by radiant or conducted heat. Hot work permit should be obtained before operation to ensure supervisor's approval that adequate precautions have been taken. After work is done, check that area is free of sparks, glowing embers, and flames. An empty container that held combustibles, or that can produce flammable or toxic vapors when heated, must OM-412 Page 2 never be weided on or cut, uniess container has first been cleaned as described in AWS Standard A6.0, listed 3 in Standards index. This includes: a thorough steam or caustic cieaning (or a solvent or water washing, depending on the com- bustible’s solubility) followed by purging and inerting with nitrogen or carbon dioxide, and using protective equipment as recommended in A6.0. Waterfilling just below working level may substitute for inerting. A container with unknown contents should be cleaned (see paragraph above). Do NOT depend on sense of smell or sight to determine ¡f it is safe to weld or cut. Hollow castings or containers must be vented before welding or cutting. They can explode. Explosive atmospheres. Never weld or cut where the air may contain flammable dust, gas, or liquid vapors (such as gasoline). D. Compressed Gas Equipment Standard precautions. Comply with precautions in this manual, and those detailed in CGA Standard P-1, PRECAUTIONS FOR SAFE HANDLING OF COMPRESSED GASES IN CYLINDERS, listed 6 in Standards index. 1. Pressure Regulators Regulator relief valve is designed to protect only the regulator from overpressure: it is not intended to protect any downstream equipment. Provide such protection with one or more relief devices. Never connect a regulator to a cylinder containing gas other than that for which the regulator was designed. Remove fauity regulator from service immediately for repair (first close cylinder valve). The following symptoms indicate a faulty regulator: Leaks - if gas leaks externally. Excessive Creep - if delivery pressure continues to rise with downstream valve closed. Faulty Gauge - if gauge pointer does not move off stop pin when pressurized, nor returns to stop pin after pressure release, Repair. Do NOT attempt repair. Send faulty regulators for repair to manufacturer's designated repair center, where special techniques and tools are used by trained personnel. 2. Cylinders | Cylinders must be handled carefully to prevent leaks and damage to their walls, valves, or safety devices: Avoid electrical circuit contact with cylinders in- cluding third rails, electrical wires, or welding cir- cuits. They can produce short circuit arcs that may lead to a serious accident. (See 1-3C.) ICC or DOT marking must be on each cylinder. It is an assurance cf safety when the cylinder is properly handled. Identifying gas content. Use only cylinders with name of gas marked on them; do not rely on color to identify gas content. Notify supplier if unmarked. NEVER DEFACE or alter name, number, or other markings on a cylinder. It is illegal and hazardous. Empties: Keep valves closed, replace caps securely; mark MT: keep them separate from FULLS and return promptly. Prohibited use. Never use a cylinder or its contents for other than its intended use, NEVER as a support or roller. Locate or secure cylinders so they cannot be knocked over. Passageways and work areas. Keep cylinders clear of areas where they may be struck. Transporting cylinders. With a crane, use a secure sup- port such as a platform or cradie. Do NOT lift cylinders off the ground by their valves or caps, or by chains, slings, or magnets. Do NOT expose cylinders to excessive heat, sparks, slag, and flame, etc. that may cause rupture. Do not allow contents to exceed 130°F. Cool with water spray where such exposure exists. Protect cylinders particularly valves from bumps, fails, falling objects, and weather. Replace caps securely when moving cylinders. Stuck valve. De NOT use a hammer or wrench to open a cylinder valve that can not be opened by hand. Notify your supplier. Mixing gases. Never try to mix any gases in a cylinder. Never refill any cylinder. Cylinder fittings should never be modified or exchang- ed. 3. Hose Prohibited use. Never use hose other than that designed for the specified gas. A general hose identification rule Is: red for fuel gas, green for oxygen, and black for inert gases. Use ferruies or clamps designed for the hose (not or- dinary wire or other substitute) as a binding to connect hoses to fittings. No copper tubing splices. Use only standard brass fit- tings to splice hose. Avoid long runs to prevent kinks and abuse. Suspend hose off ground to keep it from being run over, stepped on, or otherwise damaged. Coil excess hose to prevent kinks and tangies. Protect hose from damage by sharp edges, and by sparks, slag, and open flame. Examine hose regularly for leaks, wear, and loose con- nections. Immerse pressured hose in water; bubbles in- dicate leaks. Repair leaky or worn hose by cutting area out and splic- ing (1-203). Do NOT use tape. 4. Proper Connections Clean cylinder valve outlet of impurities that may clog orifices and damage seats before connecting regulator. Except for hydrogen, crack valve momentarily, pointing outlet away from people and sources of ignition. Wipe with a clean lintiess cloth. Match regulator to cylinder. Before connecting, check that the regulator labei and cylinder marking agree, and that the regulator inlet and cylinder outlet match. NEVER CONNECT a regulator designed for a particular gas or gases to a cylinder containing any other gas. Tighten connections. When assembling threaded con- nections, clean and smooth seats where necessary. Tighten. i connection leaks, disassemble, clean, and retighten using properly fitting wrench. Adapters. Use a CGA adapter {available from your sup- piier} between cylinder and regulator, if ane is required. Use two wrenches to tighten adapter marked RIGHT and LEFT HAND threads. Regulator outlet (or hose} connections may be iden- tified by right hand threads for oxygen and left hand threads (with grooved hex on nut or shank) for fuel gas. 5. Pressurizing Steps: Drain regulator of residual gas through suitable vent before opening cylinder {or manifold valve} by turning adjusting screw in (clockwise). Draining prevents ex- cessive compression heat at high pressure seat by allowing seat to open on pressurization. Leave adjusting screw engaged slightly on single-stage regulators. Stand to side of regulator while opening cylinder valve. Open cylinder valve slowly so that regulator pressure in- creases slowly. When gauge is pressurized {gauge reaches regulator maximum) leave cylinder valve in following position: For oxygen, and inert gases, open fully to seal stem against possible leak. For fuel gas, open-to less than one turn to permit quick emergency shutoff. Use pressure charts (available from your supplier) for safe and efficient, recommended pressure settings on regulators. Check for leaks on first pressurization and regularly there-after. Brush with soap solution (capful of ivory OM-412 Page 3 Liquid* or equivalent per galion of water). Bubbles in- dicate leak. Clean off soapy water after test: dried soap Is combustible. E. User Responsibilities Remove leaky or defective equipment from service im- mediately for repair. See User Responsibility statement in equipment manual. F. Leaving Equipment Unattended Close gas supply at source and drain gas. G. Rope Staging-Support Rope staging-support should not be used for welding or cutting operation; rope may burn. 1-3. ARC WELDING - Comply with precautions in 1-1, 1-2, and this section. Arc Welding, properly done, Is a safe process, but a careless operator invites trouble. The equipment carries high currents at significant voltages. The arc is very bright and hot. Sparks fly, fumes rise, ultraviolet and infrared energy radiates, weldments are hot, and compressed gases may be us- ed. The wise operator avoids unnecessary risks and pro- tects himself and others from accidents. Precautions are described here and in standards referenced in index. A. Burn Protection Comply with precautions in 1-2. The welding arc is intense and visibly bright. Its radia- tion can damage eyes, penetrate lightweight clothing, reflect from light-colored surfaces, and burn the skin and eyes. Skin burns resemble acute sunburn, those from gas-shielded arcs are more severe and painful. DON'T GET BURNED; COMPLY WITH PRECAU- TIONS. 1. Protective Clothing Wear long-sleeve clothing {particularly for gas-shielded arc) in addition to gloves, hat, and shoes (1-2A). As necessary, use additional protective clothing such as leather jacket or sleeves, flame-proof apron, and fire- resistant leggings. Avoid outergarments of untreated cotton. Bare skin protection. Wear dark, substantial clothing. Button collar to protect chest and neck and button pockets to prevent entry of sparks. 2. Eye and Head Protection Protect eyes from exposure to arc. NEVER look at an electric arc without protection. Welding helmet or shield containing a filter plate shade no. 12 or denser must be used when welding. Place over face before striking arc. *Trademark of Proctor & Gamble. OM-412 Page 4 Protect filter plate with a clear cover plate. Cracked or broken helmet or shield should NOT be worn; radiation can pass through to cause burns. Cracked, broken, or loose filter plates must be replaced IMMEDIATELY. Replace clear cover plate when broken, pitted, or spattered. Flash goggles with side shields MUST be worn under the helmet tc give some protection to the eyes should the helmet not be lowered over the face before an arc is struck. Locking at an arc momentarily with unprotected eyes (particularly a high intensity gas-shielded arc} can cause a retinal burn that may leave a permanent dark area in the field of vision. 3. Protection of Nearby Personnel Enclosed welding area. For production welding, a separate room or enclosed bay is best. In open areas, surround the operation with low-reflective, non- combustibie screens or panels. Allow for free air circula- tion, particularly at floor level. Viewing the weld. Provide face shields for all persons who will be locking directly at the weld. Others working in area. See that all persons are wearing flash goggles. Before starting to weld, make sure that screen flaps or bay doors are closed. B. Toxic Fume Prevention Comply with precautions in 1-2B. Generator engine exhaust must be vented to the outside air. Carbon monoxide can kill. C. Fire and Explosion Prevention Compiy with precautions in 1-2C. Equipment's rated capacity. Do not overload arc welding squipment. It may overheat cables and cause a fire. Loose cable connections may overheat or flash and cause a fire. Never strike an arc on a cylinder or other pressure vessel. It creates a brittle area that can cause a violent rupture or lead to such a rupture later under rough handling. ; D. Compressed Gas Equipment Comply with precautions in 1-2D. E. Shock Prevention Exposed hot conductors or other bare metal in the welding circuit, or in ungrounded, electrically-HOT equipment can fatally shock a person whose body becomes a conductor. DO NOT STAND, SIT, LIE, LEAN ON, OR TOUCH a wet surface when welding, without suitable protection. To protect against shock: Keep body and clothing dry. Never work in damp area without adequate insulation against electrical shock. Stay on a dry duckboard, or rubber mat when damp- ness or sweat can not be avoided. Sweat, sea water, or moisture between body and an electrically HOT part - or grounded metal - reduces the body surface electrical resistance, enabling dangerous and possibly lethal currents to flow through the body. 1. Grounding the Equipment When arc welding equipment is grounded according to the National Electrical Code, and the work is grounded according to ANSI Z49.1 ‘Safety In Welding And Cut- ing,” a voltage may exist between the electrode and any conducting object. Examples of conducting objects include, but are not limited to, buildings, electrical tools, work benches, welding power source cases, workpieces, etc. Never touch the electrode and any metal object unless the welding power source is off. When installing, connect the frames of each unit such as welding power source, control, work table, and water circulator to the building ground. Conductors must be adequate to carry ground currents safely. Equipment made electrically HOT by stray current may shock, possibly fatally. Do NOT GROUND to electrical conduit, or to a pipe carrying ANY gas ora flammable |- quid such as oil or fuel. Three-phase connection. Check phase requirements of equipment before installing. If only 3-phase power is available, connect single-phase equipment to only two wires of the 3-phase line. Do NOT connect the equip- ment ground lead to the third {live} wire, or the equip- ment will become electrically HOT - a dangerous condi- tion that can shock, possibly fatally. Before weiding, check ground for continuity. Be sure conductors are touching bare metai of equipment frames at connections. If a line cord with a ground lead is provided with the equipment for connection to a switchbox, connect the ground lead to the grounded switchbox. If a three- prong piug is added for connection to a grounded mating receptacle, the ground iead must be connected to the ground prong only. if the line cord comes with a three-prong plug, connect to a grounded mating recep- tacle. Never remove the ground prong from a plug, or use a plug with a broken off ground prong. 2. Electrode Holders Fully insulated electrode holders should be used. Do NOT use holders with protruding screws. 3. Connectors Fully insulated lock-type connectors should be used to join weiding cable lengths. 4. Cables Frequently inspect cables for wear, cracks and damage. IMMEDIATELY REPLACE those with excessively worn or damaged insulation to avoid possibly - lethal shock from bared cable. Cables with damaged areas may be taped to give resistance equivalent to original cable. Keep cable dry, free of oil and grease, and protected from hot metal and sparks. 5. Terminals And Other Exposed Parts Terminals and other exposed parts of electrical units should have insulating covers secured before operation. 6. Electrode a. Equipment with output on/off contro! (con- tactor) Welding power sources for use with the gas metal arc weíding (GMAW), gas tungsten arc welding (GTAW) and similar processes normally are equipped with devices that per- mit on-off control of the welding power out- put. When so equipped the electrode wire becomes electrically HOT when the power source switch is ON and the welding gun switch is closed. Never touch the electrode wire or any conducting object in contact with the electrode circuit unless the welding power source is off. b. Equipment without output on/off control {no contactor) Welding power sources used with shielded metal arc welding (SMAW) and similar pro- cesses may not be equipped with welding power output on-off control devices. With such equipment the electrode is electrically HOT when the power switch is turned ON. Never touch the electrode unless the welding power source is off. 7. Safety Devices Safety devices such as interlocks and circuit breakers should not be disconnected or shunted out. Before installation, inspection, or service, of equip- ment, shut OFF all power and remove line fuses {or lock ОМ-412 Раде 5 or red-tag switches) to prevent accidental turning ON of power. Disconnect all cables from welding power source, and pull ali 115 volts line-cord plugs. Do not open power circuit or change polarity while welding. If, in an emergency, it must be disconnected, guard against shock burns, or flash from switch arcing. Leaving equipment unattended. Aiways shut OFF and disconnect ail power to equipment. Power disconnect switch must be available near the welding power source. 1-4.

WELD OUTPUT CONNECTIONS (Figure 5-1) Le To obtain the full rated output from this unit, it is necessary to select, install, and maintain proper welding cables. Failure to comply in any of these areas may result in less than satisfactory welding performance. A. Welding Cables If welding cables were not ordered with this unit, the steps listed should be followed to ensure the best welding performance: 1. Keep cables as short as possible and place cables close together. Excessive cable length adds resistance which may reduce output or cause overloading of the unit. Select adequate size welding cable for the an- ticipated maximum weld current. Use. total length of welding cable in the circuit to deter- mine cable size. For example: If the electrode holder cable is 75 feet (23 m) long and the work cable is 25 feet (8 m) long, select the size cable recommended in Table 3-1 for 100 ft {31 mj. Do not use damaged or frayed cables. install electrode holder to cable following manufacturer's instructions, An insulated elec- trode holder must be used to ensure operator safety. Install a correct size lug onto one end of work cable, and install work clamp to cable. Install jack plugs onto cables as instructed in Subsection B. Table 3-1.

START SWITCH (Figure 5-1) the START switch is a spring-loaded toggle switch. Placing the switch in the START position will engage the starter. The switch must be released as soon as the engine has started to prevent damage to the starter. gerrvrdlel E: REENGAGING STARTER MOTOR while fiywheel is rotating can damage starting components. ® Do not reengage starter motor until starter pinion and flywheel have stopped rotating. 5-8. AUTOMATIC IDLE CONTROL SWITCH (Figure 5-1) - The automatic idling device reduces fuel consumption during welding operation by aliowing the engine io idle when the generator is not loaded. The Automatic idle Control switch controls the operation of the device. A. Auto idie On Na AUTO IDLE ON When the Automatic Idle contro! switch is in the AUTO IDLE ON position, the engine will remain at idle rpm, 1860 + 100 for 60 Hz. Models {1660 + 100 for 50 Hz. Models), until an arc is struck. When an arc is struck, the engine speed will increase to weld rpm (3000). Ap- proximately 15 seconds after the arc is broken, the engine will return to idle rpm. This time delay is nonad- justable. The Automatic Idle control AUTO IDLE ON position can be used for Shielded Metal-Arc Welding. B. Auto [dle Off AUTO о IDLE OFF When the Automatic Idle control switch is in the AUTO IDLE OFF position, engine speed remains at weld rpm when the generator is not loaded. 5 - 9. OIL PRESSURE SWITCH - This unit is equip- ped with an oil pressure switch S2 which automatically disconnects the battery from the excitation and idle control circuitry when the engine shuts down. | 5-10. HOUR METER (Optional) - This unit can be equipped with an hour meter. The meter, labeled TOTAL HOURS, registers the total hours of engine operation. This information is useful for routine maintenance on the engine.

Maintenance to be performed only by qualified persons. 7-1. GENERAL - The service life of this welding generator can be prolonged and operating efficiency maintained under normal conditions by following the routine service and workshop maintenance procedures outlined in this section and in the Engine Manufacturers Manual (F1L 210D Engine). Where operating conditions are severe, more frequent atten- tion must be given to all routine service categories: however a special effort must be made to maintain clean internal and external engine surfaces. 7-2. PERIODIC CLEANING AND INSPECTION - A schedule for cleaning and inspection should be set up, based on the type and conditions of service, to include the following: Keep the inside of the unit clean by blowing out the unit with clean, dry compressed air. Wipe oil and fuel spills from engine immediately to avoid accumulation of dust. 2. Place the Automatic Idle Control switch in the AUTO IDLE ON position. 3. Place the Starter switch in the START position (see Section 5-7). 4. As soon as the engine starts, release the START switch and allow the engine to run for a few minutes before applying a load. This is necessary to enable the engine tc properly warm up and en- sure proper lubrication. 6-4. STOPPING THE ENGINE 1. Remove all weld and power icads from the unit. 2. Place the Automatic Idle Control switch in the AUTO IDLE ON position. 3. Operate the engine at idle speed for 2 minutes to allow internal engine temperature to equalize. 4. Puil the RUN/STOP control fully out to the STOP position. After the engine has stopped, return the RUN/STOP control to the RUN posi- tion, M A | N ] E N A Ni C E TA NR AR INERTES ne Check for fluid leaks indicating loose oil or fuel connec- tions. Tighten loose connections and clean oi! or fuel spills or leaks off engine surfaces. iV RENE BE Periodically inspect the labels on this unit for legibility. All precautionary labels must be main- tained in a clearly readable state and replaced when necessary. See the Parts List for part number of precau- tionary labels, 7-3. AIR VENTING THE FUEL SYSTEM 1. Loosen thumb screw and slide retaining spring off hand primer on fuel pump mounted to base on left side of engine. 2. Loosen bleed screw in banjo connector at injec- tion pump {see Engine Owner's Manual for pump location). 3. Hand prime the injection pump until fuel free of bubbles emerges. 4. Lock primer pump and tighten bleed screw. 9. “Start the engine. If the engine does not run pro- репу, loosen the bleed screw until air is com- pletely vented from fuel line. Tighten bleed screw. BARES /f the engine still does not run proper- y, loosen injection line at injector (see Engine Owner's Manual for injector location}: crank engine until fuel free of bubbles emerges at injector; tighten injection fine. OM-412 Page 17 7-4. AIR CLEANER SERVICE - The air cleaner is one of the most important parts of the engine from the standpoint of engine life. An engine consumes several thousand cubic feet of air per hour when operating. If dirty air gets into the engine, it can wear out a set of piston rings within a few operating hours. See the Engine Manufacturer's Manual for oil bath air cleaner maintenance intervals and service procedures. oy {Nile DIRTY AIR can damage engine. @ Do not operate engine with dirty air cleaner. e Do not operate engine without air cleaner in place. 7-5. ELECTRICAL SYSTEM A. Cables And Wiring Check “interconnecting wiring and connections for tightness and flaws. Ensure that the weld output cable connections are clean and tight. Check the insulation for breaks or other signs of damage. Repair or replace cables or wiring as necessary. B. Battery ENDE BATTERY ACID can burn eyes and skin and destroy clothing and other materials. e Wear correct eye and body protection. Periodically inspect the battery for loose connections, defective cables, corrosion, cracked case or cover, loose holddowns, and loose or deformed terminal posts. On units equipped with conventional wet or dry charged batteries with removable vent caps, check the elec- trolyte level frequently. Add clean, mineral-free or distilled water to bring the electrolyte in each cell up to the level indicator. 7-6. IDLE CONTROL CIRCUIT PROTECTION - The idle control printed circuit board and the throttle solenoid are protected by an automatic reset circuit breaker CB1 located behind the right side panel. Normally, this circuit breaker should not trip. However, if an arc is struck or the AUTO IDLE switch is placed in the OFF position after the throttle solenoid has deenergized and the engine is slowing down, CB1 may trip. if this occurs, wait approximately one minute before resuming operation. 7-7. SPARK ARRESTOR (Optional) - Internal com- bustion engines operating in a highly combustible en- vironment are a common fire hazard. Glowing carbon particles blown out with the exhaust can retain suffi- cient heat to ignite materials. While no practical spark arresting device will stop all sparks, this device will minimize fire hazards by removing and trapping most solid particles provided that it is properly maintained. The carbon trap should be serviced weekly or every 50 operating hours, whichever occurs first. The entire spark arrestor should be inspected every 1000 operating hours or three times per season. OM-412 Page 18 A. Inspection 1. Visually examine the outside of the device for holes, cracks, or metal corrosion. 2. With the engine stopped, !ook inside the spark arrestor outlet tube with a flashlight or other light source. Visually examine the vanes and the outlet tube for metal or weid failure. The vanes must be firmly attached to the inlet tube and the outlet tube must be completely intact (this is an important factor in maintaining spark arresting efficiency). 3. Check the mounting clamp to ensure that the spark arrestor is securely mounted. Replace the spark arrestor if inspection reveals any signs of failure. -——— B. Servicing The Carbon Trap “CAUTION-: Service the device in an area where there is no danger from flying sparks or hot carbon particles. 1. Stop the engine and allow the exhaust system 16 cool. 2. Remove the cleanout plug from the bottom of the spark arrestor with a wrench. if a crust has formed over the hole, break it loose with a screwdriver or similar tool. 3. Start the engine and run it at idle rpm to blow collected particles out the cleanout hole. If par- ticles are slow to discharge, momentarily cover the end of the exhaust stack. 4. Stop the engine. Replace and secure the cleanout plug. 7-8. BRUSHES AND SLIP RINGS (Figure 7-1) - Brush life is very good under normal operating conditions. The brushes and slip rings should be in- spected every six months or whenever excitation voltage is lost. Check for cleantiness of the slip rings and freedom of motion of the brushes. If the welding generator has been operating under extremely dusty or dirty conditions, increase the frequence of inspection. 1/4 in. {6.4 mm) Minimum Figure 7 - 1. Brush Replacement TA-083 205 Under norma! use the slip rings will discolor to a dark brown. if a buildup of brush material is noted, it may be necessary to clean the slip rings. Use a 3/0 or finer sandpaper followed by a crocus cloth. Never use emery cloth as part of the emery will embed itself into the rings and in turn destroy the carbon brushes. Replace the brushes if they become chipped or broken or if less than 1/4 in. (6.4 mm) of brush material is left. 7-9. ENGINE SPEED ADJUSTMENTS (Figure 7-2) Dude AVR Engine speed adjustments should be made by an authorized diesel machanic. The engine speeds have been factory adjusted and will not require frequent readjustment. After tuning the engine, check the speeds with a tachometer. With no load applied, the power speed should be 1860 rpm for 60 Hz. Models (1650 for 50 Hz. Models} and the weld speed 3000 rpm. If necessary adjust the speeds as follows: Speed Control Lever Speed Control Plunger Knurled Nut 7 e i) CC) с) C= EF Throttie Spring Weld Speed ы Locking Nuts Locking Nut Plunger — Throttie Solenoid А-070 474 Figure 7 - 2.
