    This group of symbols means Warning! Watch Out! ELECTRICSHOCK, MOVING PARTS, and HOT PARTS hazards. Consult sym-bols and related instructions below for necessary actions to avoid thehazards.

    1-2. Arc Welding Hazards

    The symbols shown below are used throughout this manualto call attention to and identify possible hazards. When yousee the symbol, watch out, and follow the related instructionsto avoid the hazard. The safety information given below isonly a summary of the more complete safety informationfound in the Safety Standards listed in Section 1-5. Read andfollow all Safety Standards.

    Only qualified persons should install, operate, maintain, andrepair this unit.

    During operation, keep everybody, especially children, away.

    ELECTRIC SHOCK can kill.

    Touching live electrical parts can cause fatal shocksor severe burns. The electrode and work circuit iselectrically live whenever the output is on. The inputpower circuit and machine internal circuits are alsolive when power is on. In semiautomatic or automaticwire welding, the wire, wire reel, drive roll housing,and all metal parts touching the welding wire are

    electrically live. Incorrectly installed or improperlygrounded equipment is a hazard.

    Do not touch live electrical parts.

    Wear dry, hole-free insulating gloves and body protection. Insulate yourself from work and ground using dry insulating mats

    or covers big enough to prevent any physical contact with the workor ground.

    Do not use AC output in damp areas, if movement is confined, or ifthere is a danger of falling.

    Use AC output ONLY if required for the welding process. If AC output is required, use remote output control if present on

    unit. Additional safety precautions are required when any of the follow-

    ing electrically hazardous conditions are present: in damplocations or while wearing wet clothing; on metal structures suchas floors, gratings, or scaffolds; when in cramped positions suchas sitting, kneeling, or lying; or when there is a high risk of unavoid-able or accidental contact with the workpiece or ground. For theseconditions, use the following equipment in order presented: 1) asemiautomatic DC constant voltage (wire) welder, 2) a DC manual(stick) welder, or 3) an AC welder with reduced open-circuit volt-age. In most situations, use of a DC, constant voltage wire welderis recommended. And, do not work alone!

    Disconnect input power or stop engine before installing orservicing this equipment. Lockout/tagout input power according toOSHA 29 CFR 1910.147 (see Safety Standards).

    Properly install and ground this equipment according to itsOwners Manual and national, state, and local codes.

    Always verify the supply ground check and be sure that inputpower cord ground wire is properly connected to ground terminal in

    disconnect box or that cord plug is connected to a properlygrounded receptacle outlet.

    When making input connections, attach proper grounding conduc-tor first double-check connections.

    Keep cords dry, free of oil and grease, and protected from hot metal

    and sparks. Frequently inspect input power cord for damage or bare wiring replace cord immediately if damaged bare wiring can kill.

    Turn off all equipment when not in use. Do not use worn, damaged, undersized, or poorly spliced cables. Do not drape cables over your body. If earth grounding of the workpiece is required, ground it directly

    with a separate cable. Do not touch electrode if you are in contact with the work, ground,

    or another electrode from a different machine. Do not touch electrode holders connected to two welding ma-

    chines at the same time since double open-circuit voltage will bepresent.

    Use only well-maintained equipment. Repair or replace damagedparts at once. Maintain unit according to manual.

    Wear a safety harness if working above floor level. Keep all panels and covers securely in place. Clamp work cable with good metal-to-metal contact to workpiece

    or worktable as near the weld as practical. Insulate work clamp when not connected to workpiece to prevent

    contact with any metal object. Do not connect more than one electrode or work cable to any

    single weld output terminal.

    SIGNIFICANT DC VOLTAGE exists in inverter weld-ing power sources AFTER removal of inputpower. Turn Off inverter, disconnect input power, and discharge input

    capacitors according to instructions in Maintenance Sectionbefore touching any parts.

    HOT PARTS can burn.

    Do not touch hot parts bare handed. Allow cooling period before working on equip-

    ment. To handle hot parts, use proper tools and/or

    wear heavy, insulated welding gloves andclothing to prevent burns.

    Welding produces fumes and gases. Breathingthese fumes and gases can be hazardous to yourhealth.

    FUMES AND GASES can be hazardous.

    OM-230 693 Page 2

    Keep your head out of the fumes. Do not breathe the fumes.

    If inside, ventilate the area and/or use local forced ventilation at thearc to remove welding fumes and gases.

    If ventilation is poor, wear an approved air-supplied respirator.

    Read and understand the Material Safety Data Sheets (MSDSs)and the manufacturers instructions for metals, consumables,coatings, cleaners, and degreasers.

    Work in a confined space only if it is well ventilated, or whilewearing an air-supplied respirator. Always have a trained watch-person nearby. Welding fumes and gases can displace air andlower the oxygen level causing injury or death. Be sure the breath-ing air is safe.

    Do not weld in locations near degreasing, cleaning, or spraying op-erations. The heat and rays of the arc can react with vapors to formhighly toxic and irritating gases.

    Do not weld on coated metals, such as galvanized, lead, orcadmium plated steel, unless the coating is removed from the weldarea, the area is well ventilated, and while wearing an air-suppliedrespirator. The coatings and any metals containing these elementscan give off toxic fumes if welded.

    Arc rays from the welding process produce intensevisible and invisible (ultraviolet and infrared) rays

    that can burn eyes and skin. Sparks fly off from theweld.

    Wear an approved welding helmet fitted with a proper shade offilter lenses to protect your face and eyes from arc rays andsparks when welding or watching (see ANSI Z49.1 and Z87.1listed in Safety Standards).

    Wear approved safety glasses with side shields under yourhelmet.

    Use protective screens or barriers to protect others from flash,glare and sparks; warn others not to watch the arc.

    Wear protective clothing made from durable, flame-resistantmaterial (leather, heavy cotton, or wool) and foot protection.

    ARC RAYS can burn eyes and skin.

    Welding on closed containers, such as tanks,drums, or pipes, can cause them to blow up. Sparkscan fly off from the welding arc. The flying sparks, hotworkpiece, and hot equipment can cause fires and

    burns. Accidental contact of electrode to metal objects can causesparks, explosion, overheating, or fire. Check and be sure the area issafe before doing any welding.

    WELDING can cause fire or explosion.

    Remove all flammables within 35 ft (10.7 m) of the welding arc. Ifthis is not possible, tightly cover them with approved covers.

    Do not weld where flying sparks can strike flammable material.

    Protect yourself and others from flying sparks and hot metal.

    Be alert that welding sparks and hot materials from welding caneasily go through small cracks and openings to adjacent areas.

    Watch for fire, and keep a fire extinguisher nearby.

    Be aware that welding on a ceiling, floor, bulkhead, or partition cancause fire on the hidden side.

    Do not weld on closed containers such as tanks, drums, or pipes,unless they are properly prepared according to AWS F4.1 (seeSafety Standards).

    Do not weld where the atmosphere may contain flammable dust,gas, or liquid vapors (such as gasoline).

    Connect work cable to the work as close to the welding area aspractical to prevent welding current from traveling long, possiblyunknown paths and causing electric shock, sparks, and firehazards.

    Do not use welder to thaw frozen pipes.

    Remove stick electrode from holder or cut off welding wire atcontact tip when not in use.

    Wear oil-free protective garments such as leather gloves, heavyshirt, cuffless trousers, high shoes, and a cap.

    Remove any combustibles, such as a butane lighter or matches,from your person before doing any welding.

    After completion of work, inspect area to ensure it is free of sparks,glowing embers, and flames.

    Use only correct fuses or circuit breakers. Do not oversize or by-pass them.

    Follow requirements in OSHA 1910.252 (a) (2) (iv) and NFPA 51Bfor hot work and have a fire watcher and extinguisher nearby.

    FLYING METAL or DIRT can injure eyes.

    Welding, chipping, wire brushing, and grindingcause sparks and flying metal. As welds cool,they can throw off slag.

    Wear approved safety glasses with sideshields even under your welding helmet.

    BUILDUP OF GAS can injure or kill.

    Shut off shielding gas supply when not in use. Always ventilate confined spaces or use

    approved air-supplied respirator.

    ELECTRIC AND MAGNETIC FIELDS (EMF)can affect ImplantedMedical Devices.

    Wearers of Pacemakers and other ImplantedMedical Devices should keep away.

    Implanted Medical Device wearers should consult their doctorand the device manufacturer before going near arc welding, spotwelding, gouging, plasma arc cutting, or induction heatingoperations.

    NOISE can damage hearing.

    Noise from some processes or equipment can

    damage hearing. Wear approved ear protection if noise level is

    high.

    Shielding gas cylinders contain gas under highpressure. If damaged, a cylinder can explode. Sincegas cylinders are normally part of the weldingprocess, be sure to treat them carefully.

    CYLINDERS can explode if damaged.

    Protect compressed gas cylinders from excessive heat, mechani-cal shocks, physical damage, slag, open flames, sparks, and arcs.

    Install cylinders in an upright position by securing to a stationarysupport or cylinder rack to prevent falling or tipping.

    Keep cylinders away from any welding or other electrical circuits. Never drape a welding torch over a gas cylinder. Never allow a welding electrode to touch any cylinder. Never weld on a pressurized cylinder explosion will result. Use only correct shielding gas cylinders, regulators, hoses, and fit-

    tings designed for the specific application; maintain them andassociated parts in good condition.

    Turn face away from valve outlet when opening cylinder valve. Keep protective cap in place over valve except when cylinder is in

    use or connected for use. Use the right equipment, correct procedures, and sufficient num-

    ber of persons to lift and move cylinders.

    Read and follow instructions on compressed gas cylinders,associated equipment, and Compressed Gas Association (CGA)publication P-1 listed in Safety Standards.

    1-6. EMF Information

    Electr ic current flowing through any conductor causes localized electricand magnetic fields (EMF). Welding current creates an EMF field

    around the welding circuit and welding equipment. EMF fields may inter-fere with some medical implants, e.g. pacemakers. Protectivemeasures for persons wearing medical implants have to be taken. Forexample, access restrictions for passersby or individual risk assess-ment for welders. All welders should use the following procedures inorder to minimize exposure to EMF fields from the welding circuit:

    1. Keep cables close together by twisting or taping them, or using acable cover.

    2. Do not place your body between welding cables. Arrange cablesto one side and away from the operator.

    3. Do not coil or drape cables around your body.

    4. Keep head and trunk as far away from the equipment in thewelding circuit as possible.

    5. Connect work clamp to workpiece as close to the weld aspossible.

    6. Do not work next to, sit or lean on the welding power source.

    7. Do not weld whilst carrying the welding power source or wirefeeder.

    About Implanted Medical Devices:Implanted Medical Device wearers should consult their doctor and thedevice manufacturer before performing or going near arc welding, spotwelding, gouging, plasma arc cutting, or induction heating operations.If cleared by your doctor, then following the above procedures is recom-mended.

    cre un CEM autour du circuit et du matriel de soudage. Les CEMpeuvent crer des interfrences avec certains implants mdicauxcomme des stimulateurs cardiaques. Des mesures de protection pourles porteurs dimplants mdicaux doivent tre prises: par exemple, desrestrictions daccs pour les passants ou une valuation individuelledes risques pour les soudeurs. Tous les soudeurs doivent appliquer lesprocdures suivantes pour minimiser lexposition aux CEM provenantdu circuit de soudage:

    1. Rassembler les cbles en les torsadant ou en les attachant avecdu ruban adhsif ou avec une housse.

    2. Ne pas se tenir au milieu des cbles de soudage. Disposer lescbles dun ct et distance de loprateur.

    3. Ne pas courber et ne pas entourer les cbles autour de votrecorps.

    4. Maintenir la tte et le torse aussi loin que possible du matriel ducircuit de soudage.

    5. Connecter la pince sur la pice aussi prs que possible de lasoudure.

    6. Ne pas travailler proximit dune source de soudage, nisasseoir ou se pencher dessus.

    7. Ne pas souder tout en portant la source de soudage ou ledvidoir.

    En ce qui concerne les implants mdicaux :

    Les porteurs dimplants doivent dabord consulter leur mdecin avantde sapprocher des oprations de soudage larc, de soudage parpoints, de gougeage, du coupage plasma ou de chauffage par induc-tion. Si le mdecin approuve, il est recommand de suivre lesprocdures prcdentes.

    MIG Gun Runin is factory set at 100%which is recommended for most wire sizesand types.Spool Gun Runin is factory set at 50%which is recommended for .030 & .035wire. A Runin setting of 25% isrecommended for .047 wire.To check Runinsettings, start with thepower switch OFF. Press and hold the MIGor Spool Gun Trigger while turning thepower switch ON. The unit will power upwith both the displays reading888, thenthe voltage display will read runand thewire feed display will read the presetRunin percentage from memory for thegun selected. To return to the weld modewithout making a change, simply releasetrigger and pull the trigger againmomentarily (one second).

    To change Runinsettings, start with thepower switch OFF. Press and hold the MIGor Spool Gun Trigger while turning thepower switch ON. The unit will power upwith both the displays reading888, thenthe voltage display will read runand thewire feed display will read the presetRunin percentage from memory for thegun selected. To change the Runin value,release the trigger and turn the wire feedcontrol knob (or the wire feed adjustmentknob located on the bottom handle of thespool gun) to the desired setting for theselected gun. To return to weld mode afterthe Runin speed change, pull the triggermomentarily (one second).

    5-2. Voltmeter And Wire Feed Speed Meter Operation

    1 Voltmeter

    2 Wire Feed Speed Meter

    Power Up Status

    Both meters display888at unit power up.After 0.5 seconds, preset values appear onboth meters. The settings for the last activegun used will be the default at initial powerup of the unit. If the power is reset to quickly,characters other than 888 may appear. Toreset, turn power off for at least 3 seconds,then turn power back on.

    Welding Status

    When either a MIG gun or spool gun triggeris pressed and a welding arc is established,the voltmeter displays actual weld voltage.

    When the gun trigger is released andwelding arc extinguished, the voltmeterdisplays the last actual voltage for 5seconds and then returns to preset voltage.If welding resumes before unit displayspreset voltage, actual welding voltage willappear on the voltmeter.

    The wire feed speed meter always displayspreset wire feed speed (IPM).

    Gun Selection

    The wire feed speed meter will displaypreset wire feed speed (IPM) for theappropriate gun selection either MIG,

    Spool or Push/Pull gun. To preset desiredwire feed speed, connect desired gun,press gun trigger for one second, andrelease trigger. The meter preset will beretained by the meter board until a differentgun is connected and preset is performedor the unit is turned off and back on. Thesettings for the last active gun used will bethe default at initial power up of the unit.

    5-3. Jog Mode

    If the trigger on either gun is held for more than 3 seconds without striking an arc, the unit will automatically shut offweld power (and shielding gas output on MIG or push/pull gun), but will feed wire continuously at the preset wire feedspeed (which may be faster or slower than Runin Speed) until trigger is released. Jog wire feed speed is the same asweld wire feed speed, so any time jog speed is changed, be sure to change back to weld wire feed speed beforewelding. Jog wire feed speed for the spool gun and push/pull gun is limited to 300 ipm (7.6 m/min).

    Once in the TIMERSmenu, rotate the leftknob clockwise (CW) to find the particularitem, and rotate the right knob to changethe setting.

    The following items can be adjusted byrotating the left knob clockwise (CW):

    Run-in speed(run) The speed of the wireprior to the welding arc being struck. Therange is from 25 to 150% of wire feedspeed(WFS).Preflow(PrE) The amount of time thatthe shielding gas will flow after the triggeris depressed and before the welding arcwill be allowed to be active. The range isfrom 0.0 to 5.0 seconds.Postflow(POS) The amount of time thatthe shielding gas will flow after the arc hasbeen shut off. The range is from 0.0 to 10.0seconds.Burnback(Bur) The amount of time thatthe welding wire remains electrically ener-

    gized after the wire feeding has stopped.The range is from 0.01 to 0.25 seconds.

    Spot Timer(SPO) The amount of timethat the arc will be active before it shuts offautomatically. The range is from 0 to 120seconds. Spot timer is reset upon releaseof welding gun trigger.

    Stitch Timer (dLY) Used inconjunction with the Spot timer and whilethe trigger is continuously depressed.Controls the amount of time that the arc willbe inactive after the Spot timer times out.The range is from 0 to 120 seconds.

    To save settings and exit the TIMERSmenu, depress the gun trigger.
