SAFETY CONSIDERATIONSELECTRIC ARC WELDING EQUIPMENTSafteyCAUTION : READ BEFORE ATTEMPTING INSTALLATION, OPERATION ORGuidelinesMAINTENANCE OF THIS EQUIPMENT1-1 INTRODUCTIONThis equipment is intended for ultimateapplication by commercial/industrial users and foroperation by persons trained and experienced inthe use and maintenance of welding equipment.Operation should not be undertaken withoutadequate training in the use of such equipment.Training is available from many public andprivate schools or similar facilities.Safe practices in the installation, operationand maintenance of this equipment requiresproper training in the art, a careful study of theinformation provided with the equipment, andthe use of common sense. Rules for safe useare generally provided by suppliers of weldingpower sources, compressed gas suppliers,and electrode suppliers. Careful compliancewith these rules will promote safe use of thisequipment.The following Safety Rules cover some of themore generally found situations. READ THEMCAREFULLY. In case of any doubt, obtainqualified help before proceeding.1-2 GENERAL PRECAUTIONSA. Burn PreventionELECTRIC ARC WELDING PRODUCESHIGH INTENSITY HEAT AND ULTRAVIOLETRADIANT ENERGY WHICH MAY CAUSESERIOUS AND PERMANENT EYE DAMAGEAND WHICH MAY DAMAGE ANY EXPOSEDSKIN AREAS.Wear helmet with safety goggles or glasses withside shields underneath, appropriate filter lensesor plates (protected by clear cover glass). Thisis a must for welding or cutting (and chipping) toprotect the eyes from radiant energy and flyingmetal. Replace cover glass when broken, pitted,or spattered.Medical first aid and eye treatment. First aidfacilities and a qualified first aid person should beavailable for each shift unless medical facilitiesare close by for immediate treatment of flashburns of the eyes and skin burns.Wear protective clothing - leather (or asbestos)gauntlet gloves, hat, and high safety-toe shoes.Button shirt collar and pocket flaps, and wearcuffless trousers to avoid entry of sparks andslag.Avoid oily or greasy clothing. A spark may ignitethem.Flammable hair preparations should not be usedby persons intending to weld or cut.Hot metal such as electrode stubs and workpieces should never be handled without gloves.Ear plugs should be worn when working onoverhead or in a confined space. A hard hatshould be worn when others work overhead.B. Toxic Fume PreventionWARNING: The use of this product may resultin exposure to chemicals known to the State ofCalifornia to cause cancer and birth defects or otherreproductive harm.Adequate ventilation. Severe discomfort, illnessor death can result from fumes, vapors, heat, oroxygen enrichment or depletion that welding (orcutting) may produce. Prevent them with adequateventilation. NEVER ventilate with oxygen.Lead-, cadmium-, zinc-, mercury-, beryllium-bearingand similar materials, when welded or cut, mayproduce harmful concentrations of toxic fumes.Adequate 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 used.Metals coated with or containing materials that emittoxic fumes should not be heated unless coatingis removed form the work surface, the area is wellventilated, or the operator wears an air-suppliedrespirator.Work in a confined space only while it is beingventilated and, if necessary, while wearing an airsupplied respirator.Gas leaks in a confined space should be avoided.Leaked gas in large quantities can change oxygenconcentration dangerously. Do not bring gascylinders into a confined space.Leaving confined space, shut OFF gas supply atsource to prevent possible accumulation of gasesin the space if downstream valves have beenaccidentally opened or left open. Check to be surethat the space is safe before reentering it.Vapors from chlorinated solvents can bedecomposed by the heat of the arc (or flame) toform PHOSGENE, a highly toxic gas, and otherlung and eye irritating products. The ultraviolet(radiant) energy of the arc can also decomposetrichloroethylene and perchloroethylene vaporsto form phosgene. DO NOT WELD or cut wheresolvent vapors can be drawn into the welding orcutting atmosphere or where the radiant energy canpenetrate to atmospheres containing even minuteamounts of trichloroethylene or perchloroethylene.C. Fire and Explosion PreventionCauses of fire and explosion are: combustiblesreached by the arc, flame, flying sparks, hot slag, orheated material, misuse of compressed gases andcylinders, and short circuits.BE AWARE THAT flying sparks or falling slag canpass through cracks, along pipes, through windowsor doors, and through wall or floor openings, out ofsight of the goggled operator. Sparks can fly manyfeet.To prevent fires and explosion:Keep equipment clean and operable, free of oil,grease, and (in electrical parts) of metallic particlesthat can cause short circuits.If combustibles are in area, do NOT weld orcut. Move the work if practicable, to an areafree of combustibles. Avoid paint spray rooms,dip tanks, storage areas, ventilators. If the workcannot be moved, move combustibles at least 35feet away, out of reach of sparks and heat; orprotect against ignition with suitable and snugfitting, fire-resistant covers or shields.Walls touching combustibles on opposite sidesshould not be welded on (or cut). Walls, ceilings,and floor near work should be protected by heatresistant covers or shields.Fire watcher must be standing by with suitablefire extinguishing equipment during and for sometime after welding or cutting if:1. Appreciable combustibles (including buildingconstruction) are within 35 feet.2. Appreciable combustibles are further than 35feet, but can be ignited by sparks.3. Openings (concealed or visible) in floors orwalls within 35 feet may expose combustibles tosparks.4. Combustibles adjacent to walls, ceilings, roofs,or metal partitions can be ignited by radiant orconducted heat.Hot work permit should be obtained beforeoperation to ensure supervisor’s approval thatadequate precautions have been taken.After work is done, check that area is free ofsparks, glowing embers, and flames.An empty container that held combustibles, orthat can produce flammable or toxic vapors whenheated, must never be welded on or cut, unlesscontainer has first been cleaned in accordancewith industry standards.This includes: a thorough steam or causticcleaning (or a solvent of water washing,depending on the combustible’s solubility),followed by purging and inerting with nitrogen orcarbon dioxide, and using protective equipment.Water-filling just below working level maysubstitute for inerting.A container with unknown contents shouldbe cleaned (see paragraph above). Do NOTdepend on sense of smell or sight to determine ifit is safe to weld or cut.Hollow castings or containers must be ventedbefore welding or cutting. They can explode.Explosive atmospheres. NEVER weld or cutwhere the air may contain flammable dust, gas,or liquid vapors (such as gasoline).D. Compressed Gas EquipmentThe safe handling of compressed gas equipmentis detailed in numerous industry publications.The following general rules cover many of themost common situations.1. Pressure RegulatorsRegulator relief valve is designed to protect onlySidewinder MiniSpool Gun Owner's Manual - Page i

the regulator from overpressure; it is not intendedto protect any downstream equipment. Providesuch protection with one or more relief devices.Never connect a regulator to a cylinder containinggas other than that for which the regulator wasdesigned.Remove faulty regulator from service immediatelyfor repair (first close cylinder valve). Thefollowing symptoms indicate a faulty regulator:Leaks - if gas leaks externally.Excessive Creep - if delivery pressure continuesto rise with downstream valve closed.Faulty Gauge - if gauge pointer does not moveoff stop pin when pressurized, nor returns to stoppin after pressure release.Repair. Do NOT attempt repair. Send faultyregulators for repair to manufacturer’s designatedrepair center, where special techniques and toolsare used by trained personnel.2. CylindersCylinders must be handled carefully to preventleaks and damage to their walls, valves, or safetydevices:Avoid electrical circuit contact with cylindersincluding third rails, electrical wires, or weldingcircuits. They can produced short circuit arcsthat may lead to a serious accident. (See 1-3C)ICC or DOT marking must be on each cylinder.It is an assurance of safety when the cylinder isproperly handled.Identifying gas content. Use only cylinders withname of gas marked on them; do not rely oncolor to identify gas content. Notify supplier ifunmarked. NEVER DEFACE or alter name,number, or other markings on a cylinder. It isillegal and hazardous.Empties: Keep valves closed, replace capssecurely; mark MT; keep them separate fromFULLS, and return promptly.Prohibited use. Never use a cylinder or itscontents for other than its intended use, NEVERas a support or roller.Locate or secure cylinders so they cannot beknocked over.Passageways and work areas. Keep cylindersclear of areas where they may be stuck.Transporting cylinders. With a crane, use asecure support such as a platform or cradle. DoNOT lift cylinders off the ground by their valves orcaps, or by chains, slings, or magnets.Do NOT expose cylinders to excessive heat,sparks, slag, and flame, etc. that may causerupture. Do not allow contents to exceed 55degrees C (130 degrees F.) Cool with waterspray where such exposure exists.Protect cylinders, particularly valves from bumps,falls, falling objects, and weather. Replace capssecurely when moving cylinders.Stuck valve. Do NOT use a hammer or wrench toopen a cylinder valve that cannot be opened byhand. Notify your supplier.Mixing gases. NEVER try to mix any gases ina cylinder.NEVER refill any cylinder.Cylinder fittings should never be modified orexchanged.3. HoseProhibited use. Never use hose other than thatdesigned for the specified gas. A general hoseidentification rule is: red for fuel gas, green foroxygen, and black for inert gases.Use ferrules or clamps designed for the hose (notordinary wire or other substitute) as a binding toconnect hoses to fittings.No copper tubing splices. Use only standard brassfittings to splice hose.Avoid long runs to prevent kinks and abuse.Suspend hose off ground to keep it from being runover, stepped on, or otherwise damaged.Coil excess hose to prevent kinks and tangles.Protect hose from damage by sharp edges, and bysparks, slag, and open flame.Examine hose regularly for leaks, wear, and looseconnections. Immerse pressured hose in water;bubbles indicate leaksRepair leaky or worn hose by cutting area out andsplicing. Do NOT use tape.4. Proper ConnectionsClean cylinder valve outlet of impurities that mayclog orifices and damage seats before connectingregulator. Except for hydrogen, crack valvemomentarily, pointing outlet away from people andsources of ignition. Wipe with a clean, lintless cloth.Match regulator to cylinder. Before connecting,check that the regulator label and cylinder markingagree, and that the regulator inlet and cylinder outletmatch. NEVER Connect a regulator designed for aparticular gas or gases to a cylinder containing anyother gas.Tighten connections.When assemblingthreaded connections, clean and smooth seatswhere necessary. Tighten. If connection leaks,disassemble, clean, and retighten, using properlyfitting wrench.Adapters. Use a CGA adapter (available from yoursupplier) between cylinder and regulator, if one isrequired. Use two wrenches to tighten adaptermarked RIGHT and LEFT HAND threads.Regulator outlet (or hose) connections may beidentified by right hand threads for oxygen and lefthand threads (with grooved hex on nut or shank) forfuel gas.5. Pressurizing Steps:Drain regulator of residual gas through suitable ventbefore opening cylinder (or manifold valve) by turningadjusting screw in (clockwise). Draining preventsexcessive compression heat at high pressure seatby allowing seat to open on pressurization. Leaveadjusting screw engaged slightly on single-stageregulators.Stand to side of regulator while opening cylindervalve.Open cylinder valve slowly so that regulator pressureincreases slowly. When gauge is pressurized(gauge reaches regulator maximum) leave cylindervalve in following position: for oxygen and inertgases, open fully to seal stem against possible leak;for fuel gas, open to less than one turn to permitquick emergency shut-off.Use pressure charts (available from your supplier)for safe and efficient recommended pressuresettings on regulators.Check for leaks on first pressurization and regularlythereafter. Brush with soap solution. Bubblesindicate leaks. Clean off soapy water after test;dried soap is combustible.E. User ResponsibilitiesFollow all Safety Rules.Remove leaky or defective equipment fromservice immediately for repair. Read and followuser manual instructions.F. Leaving EquipmentUnattendedClose gas supply at source and drain gas.G. Rope Staging-SupportRope staging-support should not be used forwelding or cutting operation; rope may burn.1-3 ARC WELDINGComply with precautions in 1-1, 1-2, and thissection. Arc Welding, properly done, is a safeprocess, but a careless operator invites trouble.The equipment carries high currents at significantvoltages. The arc is very bright and hot. Sparksfly, fumes rise, ultraviolet and infrared energyradiates, weldments are hot, and compressedgases may be used. The wise operator avoidsunnecessary risks and protects himself andothers from accidents.A. Burn ProtectionComply with precautions in 1-2.The welding arc is intense and visibly bright. Itsradiation can damage eyes, penetrate lightweightclothing, reflect from light-colored surfaces, andburn the skin and eyes. Skin burns resembleacute sunburn; those from gas-shielded arcs aremore severe and painful. DON’T GET BURNED;COMPLY WITH PRECAUTIONS.1. Protective ClothingWear long-sleeve clothing in addition to gloves,hat, and shoes. As necessary, use additionalprotective clothing such as leather jacket orsleeves, flameproof apron, and fire-resistantleggings. Avoid outer garments of untreatedcotton.Bare skin protection. Wear dark, substantialclothing. Button collar to protect chest and neck,and button pockets to prevent entry of sparks.2. Eye and Head ProtectionProtect eyes from exposure to arc. Eyes maybe damaged by radiant energy when exposedto the electric arc, even when not looking in thedirection of the arc. Never look at an electric arcwithout protection.Welding helmet or shield containing a filter plateshade no. 12 or denser must be used whenwelding. Place over face before striking arc.Protect filter plate with a clear cover plate.Cracked or broken helmet or shield should NOTbe worn; radiation can be passed through tocause burns.Cracked, broken, or loose filter plates must bereplaced IMMEDIATELY. Replace clear coverplate when broken, pitted, or spattered.Flash goggles with side shields MUST be wornunder the helmet to give some protection to theeyes should the helmet not be lowered over theface before an arc is struck. Looking at an arcmomentarily with unprotected eyes (particularlya high intensity gas-shielded arc) can cause aSidewinder MiniSpool Gun Owner's Manual - Page ii

retinal burn that may leave a permanent darkarea in the field of vision.or the equipment will become electrically HOT - adangerous condition that can shock, possibly fatally.3. Protection of Nearby PersonnelEnclose the welding area. For productionwelding, a separate room or enclosed bay isbest. In open areas, surround the operationwith low-reflective, noncombustible screens orpanels. Allow for free air circulation, particularlyat floor level.Before welding, check ground for continuity. Be sureconductors are touching bare metal of equipmentframes at connections.Viewing the weld. Provide face shields for allpersons who will be looking directly at the weld.Others working in area. See that all persons arewearing flash goggles.Before starting to weld, make sure that scr
