WARNING: These Safety Precautions are foryour protection. They summarize precaution-ary information from the references listed inAdditional Safety Information section. Before

performing any installation or operating procedures, besure to read and follow the safety precautions listed belowas well as all other manuals, material safety data sheets,labels, etc. Failure to observe Safety Precautions can resultin injury or death.

PROTECT YOURSELF AND OTHERS --Some welding, cutting, and gougingprocesses are noisy and require earprotection. The arc, like the sun, emitsultraviolet (UV) and other radiation and

can injure skin and eyes. Hot metal can cause burns.Training in the proper use of the processes and equip-ment is essential to prevent accidents. Therefore:

1. Always wear safety glasses with side shields in any workarea, even if welding helmets, face shields, and gogglesare also required.

2. Use a face shield fitted with the correct filter and coverplates to protect your eyes, face, neck, and ears fromsparks and rays of the arc when operating or observingoperations. Warn bystanders not to watch the arc andnot to expose themselves to the rays of the electric-arcor hot metal.

3. Wear flameproof gauntlet type gloves, heavy long-sleeveshirt, cuffless trousers, high-topped shoes, and a weld-ing helmet or cap for hair protection, to protect againstarc rays and hot sparks or hot metal. A flameproof apronmay also be desirable as protection against radiatedheat and sparks.

4. Hot sparks or metal can lodge in rolled up sleeves,trouser cuffs, or pockets. Sleeves and collars should bekept buttoned, and open pockets eliminated from thefront of clothing

5. Protect other personnel from arc rays and hot sparkswith a suitable non-flammable partition or curtains.

6. Use goggles over safety glasses when chipping slag orgrinding. Chipped slag may be hot and can fly far.Bystanders should also wear goggles over safety glasses.

FIRES AND EXPLOSIONS -- Heat fromflames and arcs can start fires. Hot slagor sparks can also cause fires and ex-plosions. Therefore:

1. Remove all combustible materials well away from thework area or cover the materials with a protective non-flammable covering. Combustible materials include wood,cloth, sawdust, liquid and gas fuels, solvents, paints andcoatings, paper, etc.

2. Hot sparks or hot metal can fall through cracks orcrevices in floors or wall openings and cause a hiddensmoldering fire or fires on the floor below. Make certainthat such openings are protected from hot sparks andmetal.“

3. Do not weld, cut or perform other hot work until theworkpiece has been completely cleaned so that thereare no substances on the workpiece which might pro-duce flammable or toxic vapors. Do not do hot work onclosed containers. They may explode.

4. Have fire extinguishing equipment handy for instant use,such as a garden hose, water pail, sand bucket, orportable fire extinguisher. Be sure you are trained in itsuse.

SAFETY PRECAUTIONS

5. Do not use equipment beyond its ratings. For example,overloaded welding cable can overheat and create a firehazard.

6. After completing operations, inspect the work area tomake certain there are no hot sparks or hot metal whichcould cause a later fire. Use fire watchers when neces-sary.

7. For additional information, refer to NFPA Standard 51B,"Fire Prevention in Use of Cutting and Welding Pro-cesses", available from the National Fire Protection Asso-ciation, Batterymarch Park, Quincy, MA 02269.

ELECTRICAL SHOCK -- Contact with liveelectrical parts and ground can causesevere injury or death. DO NOT use ACwelding current in damp areas, if move-ment is confined, or if there is danger offalling.

1. Be sure the power source frame (chassis) is connectedto the ground system of the input power.

2. Connect the workpiece to a good electrical ground.3. Connect the work cable to the workpiece. A poor or

missing connection can expose you or others to a fatalshock.

4. Use well-maintained equipment. Replace worn or dam-aged cables.

5. Keep everything dry, including clothing, work area, cables,torch/electrode holder, and power source.

6. Make sure that all parts of your body are insulated fromwork and from ground.

7. Do not stand directly on metal or the earth while workingin tight quarters or a damp area; stand on dry boards oran insulating platform and wear rubber-soled shoes.

8. Put on dry, hole-free gloves before turning on the power.9. Turn off the power before removing your gloves.

10. Refer to ANSI/ASC Standard Z49.1 (listed on next page)for specific grounding recommendations. Do not mistakethe work lead for a ground cable.

ELECTRIC AND MAGNETIC FIELDS —May be dangerous. Electric current flow-ing through any conductor causes lo-calized Electric and Magnetic Fields(EMF). Welding and cutting current cre-ates EMF around welding cables andwelding machines. Therefore:

1. Welders having pacemakers should consult their physi-cian before welding. EMF may interfere with some pace-makers.

2. Exposure to EMF may have other health effects which areunknown.

3. Welders should use the following procedures to minimizeexposure to EMF:A. Route the electrode and work cables together. Secure

them with tape when possible.B. Never coil the torch or work cable around your body.C. Do not place your body between the torch and work

cables. Route cables on the same side of your body.��

FUMES AND GASES -- Fumes andgases, can cause discomfort or harm,particularly in confined spaces. Donot breathe fumes and gases. Shield-ing gases can cause asphyxiation.Therefore:

1. Always provide adequate ventilation in the work area bynatural or mechanical means. Do not weld, cut, or gougeon materials such as galvanized steel, stainless steel,copper, zinc, lead, beryllium, or cadmium unless positivemechanical ventilation is provided. Do not breathe fumesfrom these materials.

2. Do not operate near degreasing and spraying opera-tions. The heat or arc rays can react with chlorinatedhydrocarbon vapors to form phosgene, a highly toxicgas, and other irritant gases.

3. If you develop momentary eye, nose, or throat irritationwhile operating, this is an indication that ventilation is notadequate. Stop work and take necessary steps to im-prove ventilation in the work area. Do not continue tooperate if physical discomfort persists.

4. Refer to ANSI/ASC Standard Z49.1 (see listing below)for specific ventilation recommendations.

5. WARNING: This product, when used for welding orcutting, produces fumes or gases whichcontain chemicals known to the State ofCalifornia to cause birth defects and, insome cases, cancer. (California Health &Safety Code �25249.5 et seq.)

CYLINDER HANDLING -- Cylinders, ifmishandled, can rupture and violentlyrelease gas. Sudden rupture of cylin-der, valve, or relief device can injure orkill. Therefore:

1. Use the proper gas for the process and use the properpressure reducing regulator designed to operate fromthe compressed gas cylinder. Do not use adaptors.Maintain hoses and fittings in good condition. Followmanufacturer's operating instructions for mounting regu-lator to a compressed gas cylinder.

2. Always secure cylinders in an upright position by chainor strap to suitable hand trucks, undercarriages, benches,walls, post, or racks. Never secure cylinders to worktables or fixtures where they may become part of anelectrical circuit.

3. When not in use, keep cylinder valves closed. Havevalve protection cap in place if regulator is not con-nected. Secure and move cylinders by using suitablehand trucks. Avoid rough handling of cylinders.

4. Locate cylinders away from heat, sparks, and flames.Never strike an arc on a cylinder.

5. For additional information, refer to CGA Standard P-1,"Precautions for Safe Handling of Compressed Gases inCylinders", which is available from Compressed GasAssociation, 1235 Jefferson Davis Highway, Arlington,VA 22202.

EQUIPMENT MAINTENANCE -- Faulty orimproperly maintained equipment cancause injury or death. Therefore:

1. Always have qualified personnel perform the installa-tion, troubleshooting, and maintenance work. Do notperform any electrical work unless you are qualified toperform such work.

2. Before performing any maintenance work inside a powersource, disconnect the power source from the incomingelectrical power.

3. Maintain cables, grounding wire, connections, powercord, and power supply in safe working order. Do notoperate any equipment in faulty condition.

4. Do not abuse any equipment or accessories. Keepequipment away from heat sources such as furnaces,wet conditions such as water puddles, oil or grease,corrosive atmospheres and inclement weather.

5. Keep all safety devices and cabinet covers in positionand in good repair.

6. Use equipment only for its intended purpose. Do notmodify it in any manner.

a. Éloigner suffisamment tous les matériaux combus-tibles du secteur où l’on exécute des soudures ou descoupes à l’arc, à moins de les recouvrir complètementd’une bâche non-inflammable. Ce type de matériauxcomprend notamment le bois, les vêtements, la sciure,l’essence, le kérosène, les peintures, les solvants, legaz naturel, l’acétylène, le propane et autres sub-stances combustibles semblables.

b. Les étincelles ou les projections de métal incandes-cent peuvent tomber dans des fissures du plancher oudans des ouvertures des murs et y déclencher uneignition lente cachée. Veiller à protéger ces ouverturesdes étincelles et des projections de métal.

c. N’exécutez pas de soudures, de coupes, d’opérationsde gougeage ou autres travaux à chaud à la surfacede barils, bidons, réservoirs ou autres contenantsusagés, avant de les avoir nettoyés de toute trace desubstance susceptible de produire des vapeursinflammables ou toxiques.

d. En vue d’assurer la prévention des incendies, ilconvient de disposer d’un matériel d’extinction prêt àservir immédiatement, tel qu’un tuyau d’arrosage, unseau à eau, un seau de sable ou un extincteur portatif.

e. Une fois le travail à l’arc terminé, inspectez le secteurde façon à vous assurer qu’aucune étincelle ou projec-tion de métal incandescent ne risque de provoquerultérieurement un feu.

3. CHOC ÉLECTRIQUE-- Le gougeage à l’arc et à l’arcau plasma exige l’emploi de tensions à viderelativement importantes; or, celles-ci risquent decauser des dommages corporels graves et mêmemortels en cas d’utilisation inadéquate. La gravité duchoc électrique reçu dépend du chemin suivi par lecourant à travers le corps humain et de son intensité.

a. Ne laissez jamais de surfaces métalliques sous ten-sion venir au contact direct de la peau ou devêtements humides. Veillez à porter des gants biensecs.

b. Si vous devez effectuer un travail sur une surfacemétallique ou dans un secteur humide, veillez à assu-rer votre isolation corporelle en portant des gants secset des chaussures à semelles de caoutchouc et envous tenant sur une planche ou une plate-formesèche.

c. Mettez toujours à la terre le poste de soudage/coupageen le reliant par un câble à une bonne prise de terre.

d. N’utilisez jamais de câbles usés ou endommagés. Nesurchargez jamais le câble. Utilisez toujours unéquipement correctement entretenu.

e. Mettez l’équipement hors tension lorsqu’il n’est pas enservice. une mise à la masse accidentelle peut eneffet provoquer une surchauffe de l’équipement et undanger d’incendie. Ne pas enrouler ou passer le câbleautour d’une partie quelconque du corps.

f. Vérifiez si le câble de masse est bien relié à la pièce enun point aussi proche que possible de la zone detravail. Le branchement des câbles de masse àl’ossature du bâtiment ou en un point éloigné de lazone de travail augmente en effet le risque de pas-sage d’un courant de sortie par des chaînes de

�� AVERTISSEMENT: Ces règles de sécurité ont pour objetd’ assurer votre protection. Veillez à lire et à observer lesprécautions énoncées ci-dessous avant de monter l’équipement ou de commercer à l’utiliser. Tout défautd’observation de ces précautions risque d’entraîner desblessures graves ou mortelles.1. PROTECTION INDIVIDUELLE-- Les brûlures de la

peau et des yeux dues au rayonnement de l’arcélectrique ou du métal incandescent, lors du soudageau plasma ou à l’électrode ou lors du gougeage àl’arc, peuvent s’avérer plus graves que cellesrésultant d’une exposition prolongée au soleil. Aussiconvient-il d’observer les précautions suivantes:

a. Portez un écran facial adéquat muni des plaquesprotectrices et des verres filtrants appropriés afin devous protéger les yeux, le visage, le cou et les oreillesdes étincelles et du rayonnement de l’arc électriquelorsque vous effectuez des soudures ou des coupesou lorsque vous en observez l’exécution.

AVERTISSEZ les personnes se trouvant à proximitéde façon à ce qu’elles ne regardent pas l’arc et à cequ’elles ne s’exposent pas à son rayonnement, ni àcelui du métal incandescent.

b. Portez des gants ignifugés à crispins, une tuniqueépaisse à manches longues, des pantalons sansrebord, des chaussures à embout d’acier et uncasque de soudage ou une calotte de protection, afind’éviter d’exposer la peau au rayonnement de l’arcélectrique ou du métal incandescent. ll est égalementsouhaitable d’utiliser un tablier ininflammable defaçon à se protéger des étincelles et du rayonnementthermique.

c. Les étincelles ou les projections de métal incandes-cent risquent de se loger dans des manchesretroussées, des bords relevés de pantalons ou dansdes poches. Aussi convient-il de garder boutonnés lecol et les manches et de porter des vêtements sanspoches à l’avant.

d. Protégez des étincelles et du rayonnement de l’arcélectrique les autres personnes travaillant à proximitéà l’aide d’un écran ininflammable adéquat.

e. Ne jamais omettre de porter des lunettes de sécuritélorsque vous vous trouvez dans un secteur où l’oneffectue des opérations de soudage ou de coupage àl’arc. Utilisez des lunettes de sécurité à écrans ouverres latéraux pour piquer ou meûler le laitier. Lespiquetures incandescentes de laitier peuvent êtreprojetées à des distances considérables. Lespersonnes se trouvant à proximité doivent égalementporter des lunettes de protection.

f. Le gougeage à l’arc et le soudage à l’arc au plasmaproduisent un niveau de bruit extrêmement élevé (de100 à 114 dB) et exigent par conséquent l’emploi dedispositifs appropriés de protection auditive.

2. PRÉVENTION DES INCENDES-- Les projections delaitier incandescent ou d’étincelles peuventprovoquer de graves incendies au contact dematériaux combustibles solides, liquides ou gazeux.Aussi faut-il observer les précautions suivantes:

levage, des câbles de grue ou divers cheminsélectriques.

g. Empêchez l’apparition de toute humidité, notammentsur vos vêtements, à la surface de l’emplacement detravail, des câbles, du porte-électrode et du poste desoudage/coupage. Réparez immédiatement toutefuite d’eau.

4. VENTILATION-- La respiration prolongée des fuméesrésultant des opérations de soudage/coupage, àl’intérieur, d’un local clos, peut provoquer des mal-aises et des dommages corporels. Aussi convient-ild’observer les précautions suivantes:

a. Assurez en permanence une aération adéquate del’emplacement de travail en maintenant une ventila-tion naturelle ou à l’aide de moyens mécaniques.N’effectuez jamais de travaux de soudage ou decoupage sur des matériaux de zinc, de plomb, deberyllium ou de cadmium en l’absence de moyensmécaniques de ventilation capables d’empêcherl’inhalation des fumées dégagées par ces matériaux.

b. N’effectuez jamais de travaux de soudage ou decoupage à proximité de vapeurs d’hydrocarburechloré résultant d’opérations voisines de dégraissageou de pulvérisation. La chaleur dégagée ou lerayonnement de l’arc peut déclencher la formation dephosgène -- gaz particulièrement toxique -- et d’autresgaz irritants, à partir des vapeurs de solvant.

c. Une irritation momentanée des yeux, du nez ou de lagorge constatée au cours de l’utilisation del’équipement dénote un défaut de ventilation. Arrêtez-vous de travailler afin de prendre les mesures néces-saires à l’amélioration de la ventilation. Ne poursuivezpas l’opération entreprise si le malaise persiste.

d. Certaines commandes comportent des canalisationsoù circule de l’hydrogène. L’armoire de commande estmunie d’un ventilateur destiné à empêcher la forma-tion de poches d’hydrogène, lesquelles présentent undanger d’explosion; ce ventilateur ne fonctionne quesi l’interrupteur correspondant du panneau avant setrouve placé en position ON (Marche). Veillez àmanœuvrer cette commande en vérifiant si lecouvercle est bien en place, de façon à assurerl’efficacité de la ventilation ainsi réalisée. Ne jamaisdébrancher le ventilateur.

e. Les fumées produites par l’opération de soudage oude coupage peuvent s’avérer toxiques. Aussi est-ilnécessaire de disposer en permanence d’un dispositifadéquat de ventilation de type aspirant, afin d’élimi-ner du voisinage de l’opérateur tout dégagement defumée visible.

f. Consultez les recommandations particulières enmatière de ventilation indiquées à l’alinéa 6 de lanorme Z49.1 de l’AWS.

5. ENTRETIEN DE L’ÉQUIPEMENT-- Un équipemententretenu de façon défectueuse ou inadéquate risquenon seulement de réaliser un travail de mauvaise

qualité mais, chose plus grave encore, d’entraîner desdommages corporels graves, voire mortels endéclenchant des incendies ou des chocs électriques.Observez par conséquent les précautions suivantes:

a. Efforcez-vous de toujours confier à un personnel qua-lifié l’installation, le dépannage et l’entretien du postede soudage et de coupage. N’effectuez aucuneréparation électrique sur l’équipement à moins d’êtrequa-lifié à cet effet.

b. Ne procédez jamais à une tâche d’entretienquelconque à l’intérieur du poste de soudage/coupage, avant d’avoir débranché l’alimentationélectrique.

c. Maintenez en bon état de fonctionnement les câbles,le câble de masse, les branchements, le cordond’alimentation et le poste de soudage/coupage.N’utilisez jamais le poste ou l’équipement s’il présenteune défectuosité quelconque.

d. Prenez soin du poste de soudage et de coupage etdes équipements accessoires. Gardez-les à l’écartdes sources de charleur, notamment des fours, del’humidité, des flaques d’eau maintenez-les à l’abri destraces d’huile ou de graisse, des atmosphères corro-sives et des intempéries.

e. Laissez en place tous les dispositifs de sécurité et tousles panneaux de l’armoire de commande en veillant àles garder en bon état.

f. Utilisez le poste de soudage/coupage conformément àson usage prévu et n’effectuez aucune modification.

2.5 SAFETY

Before the equipment is put into operation, the safetysection at the front of this manual should be readcompletely. This will help avoid possible injury due tomisuse or improper welding applications.

The symbol which precedes safety notes appear-ing throughout this manual means “Attention! Be Alert!Your safety is involved.” The definitions relating to theDANGER, WARNING and CAUTION safety notationsare described at the end of the Safety Section in the frontof this manual -- read them and their specific textreferences carefully.

III. INSTALLATION

3.1 LOCATION (Figure 3.1)

A proper installation site should be selected for thewelding machine, if the unit is to provide dependableservice and remain relatively maintenance free.

A proper installation site permits freedom of air move-ment into and out of the welding machine, and also leastsubjects the unit to dust, dirt, moisture, and corrosivevapors. A minimum of 18 inches (46 cm) unrestrictedspace must be maintained between the welding ma-chine side and rear panels and the nearest obstruction.

The installation site should also permit easy removal ofthe welding machine outer enclosure for maintenancefunctions.

CAUTION: Do not place any filtering device over theintake air passages of the welding ma-chine as this would restrict the volume ofintake air and thereby subject the weldingmachine internal components to an over-heating condition and subsequent failure.Warranty is void if any type of filteringdevice is used.

If a forklift vehicle is used for lifting the unit, be sure thatthe lift forks are long enough to extend completely underthe base.

Do not operate the machine without the runninggear installed.

3.2 ELECTRICAL INPUT CONNECTIONS

It is recommended that a line disconnect switch beinstalled in the input circuit to the welding machine.This would provide a safe and convenient means tocompletely remove all electrical power from thewelding machine whenever it is necessary to performany internal function on the unit. (See Figure 3.2A.)

Before making electrical input connections to thewelding machine, “Machinery Lockout Procedures”should be employed. If the connections are to bemade from a line disconnect switch, the switchshould be padlocked in the off position. If the con-nection is made from a fusebox, remove the fusesfrom the box and padlock the cover in the closedposition. If locking facilities are not available, attacha red tag to the line disconnect switch (or fuse box)to warn others that the circuit is being worked on. Ifthe plug-cap is used, (see 3.2B) remove plug fromreceptacle.

Only qualified personnel should make thesechanges. Make certain the primary power has beendisconnected and all safety procedures have beenfollowed before proceeding with these instructions.

Fig. 3.3A shows the 230v and 208v connections for the208/230 dual voltage model. Change over is made byremoving the right side panel below the wire feed com-partment and switching the primary transformer tap atthe top of the power switch with the unused alternatevoltage tap located next to the main transformer (seeFig. 3.3B). Both voltage taps (the one currently con-nected to the switch and the unused alternate voltage)are marked with the input voltage requirement. All unitsare supplied from the factory connected for the highestvoltage (230 vac). Before switching the voltage taps,verify the actual voltage requirement as well as thecurrent voltage connection to be certain re-connection isnecessary. If voltage tap re-connection is necessary, thefollowing paragraphs cover the procedure to switch the

When changing the input voltage connections, theunused lead must be insulated and positioned toprevent contact with any other internal componentsof the machine or the machine side panel. The clear-ance between the unused lead and other compo-nents must be at least one inch (see Fig. 3.3B forillustration of the proper position). FAILURE TOINSULATE AND POSITION THIS LEAD PROPERLYWILL CAUSE A SERIOUS SHOCK HAZARD.

voltage tap for either 208vac or 230vac input.

Figure 3.3A - Primary Reconnections at SwitchFor 208/230 Volt Models

The terminal labeled GRD is connected to the weld-ing machine chassis and is for ground purposesonly. It must be connected to a good electricalground. Do not connect a conductor from the termi-nal labeled GRD to any one of the L1, L2 terminals asthis will result in an electrically hot welding machinechassis.

3.2.3 Connecting FOR 208 VAC INPUT

After the panel is removed, locate the 208 Vac lead (Fig.3.3B) and cut the tie-wrap to remove the insulationsleeving (on early models this lead may have beenwrapped with black electrical tape). Open the insulatingcover around the power switch (Fig. 3.3C.) to expose theterminals and disconnect the 230 Vac lead from the topof the switch as shown in Fig. 3.3A. Insulate the 230 Vaclead that was removed from the power switch withsleeving or approved electrical tape and re-position to asafe area beside the transformer (see Fig. 3.3B), leavinga minimum of one inch clearance from other compo-nents and the side panel.

sleeving (on early models this lead may have beenwrapped with black electrical tape). Open the insulatingcover around the power switch (Fig. 3.3C.) to expose theterminals and disconnect the 208 Vac lead from the topof the switch as shown in Fig. 3.3A. Insulate the 208 Vaclead that was removed from the power switch withsleeving or approved electrical tape and re-position to asafe area beside the transformer (see Fig. 3.3B), leavinga minimum of one inch clearance from other componentsand the side panel.

Connect the proper voltage (208 Vac or 230 Vac) tap tothe power switch and tighten securely. Check all otherleads connected to the power switch for tightness andclearance from internal components before securing theinsulating cover around the power switch. Replace theside panel.

3.2.5 Reconnecting from 575 VAC Input

Figure 3.3.1 shows you how to reconnect the "multi-voltage" model from a 575-volt input to any of theremaining available voltage inputs 200 or 380 or 400 or460-volts. These connections are made by unscrewingthe right side panel below the wire feeding compartment,and locating the primary voltage changeover terminalboard handing in the center of the lower compartment.This board contains copper links which must be recon-nected to match the silk-screened voltage designationsfor the input you plan to use (it comes factory-connectedfor a 575-volt input), see Figure 3.3.1.

3.3 SECONDARY OUTPUT CONNECTIONS

The Migmaster 250 Welding System is completely self-contained so that the front panel torch fittings (Euro-typeMT and Spool gun) are internally connected to thewelding polarity (D.C. Reverse or D.C. Straight) via thesecondary output terminals located inside the wire feed-ing compartment (see Fig. 4.1). The machine comes setup for D.C.R.P. welding as described in Section 4.1.3.

3.4 TORCH CONNECTIONS

The torch (GUNMASTER 250), which is supplied asstandard equipment with the Migmaster 250 System, isprovided with a euro-type adapter which directly con-nects to the torch fitting mounted on the front panel. Lineup matching holes, push on and tighten locking collar. Asshipped from the factory, the euro or common connectortype torches are set-up for D.C.R.P. welding polarity(see sections 3.3 or 4.1.3). To connect the spool-on-guntorch (ST-23A) see Section 4.2.2.

3.5 WIRE FEEDER MECHANISM

3.5.1 DRIVE ROLLS

The drive roll has two grooves: the small groove feeds0.035 in. diameter wire, the large groove feeds 0.045 in.wire. The groove nearest the gear motor feeds the wire.If the required groove is not in that position:

A. Release the pressure drive roll lever and lift theassembly upward.

B. Remove the two (2) screws holding the drive roll tothe gear.

3.5.2 WELDING WIRE SPOOL

As with any work area, make sure safety glasseswith side shields are worn when handling or chang-ing wire or clipping wire off at the spool or at the endof the torch. Hold onto the wire coming off the spoolwith one hand before clipping. Serious eye injurycan result due to the springiness of the wire whichcan quickly unravel, or a cut wire end which mayshoot across the room.

Install a spool of welding wire on the hub as follows:

A. Unscrew spool nut from hub.B. Place wire spool on hub to rotate clockwise as wire

is unwound; hub pin must engage hole in spool.C. Replace nut.

3.5.3 THREADING WELDING WIRE

A. Turn off power switch.

When the power switch is on, and gun trigger isdepressed, the electrode wire becomes electricallyhot, and the wire feed rolls are activated.

B. Release pressure drive roll assembly and lift upward. Check that proper wire diameter groove is inthe inner position.

CAUTION: Before threading welding wire through cas-ing, make sure chisel point and burrs havebeen removed from wire end to prevent wirefrom jamming in gun casing or liner.

C. Feed the wire from the spool through the inletguide, across the drive roll groove and into gunoutlet guide.

Make sure that the proper “outlet guide tube” is insertedinto the front-panel gun fitting for the size and type of wirebeing used, see Table 2.4.5.2 for wire feed accessories(Section 2.4.5).

To insure proper wire feeding, it is important that the wirebe kept clean and that the drive rolls be periodicallycleaned of any chips or scale that might be carried intothe gun liner and cause sticking.

D. Lower pressure roll assembly and secure. Checkthat the gears mesh. Feed wire through to gun tipwith gun trigger (power ON).

3.5.4 BRAKE DRAG ADJUSTMENT

Brake disc friction should provide enough drag to keepthe wire spool or core from spinning freely after wire feedstops. If adjustment is required, turn adjusting screwclockwise to increase drag, counterclockwise to de-crease it. Drag should be just low enough to limit wireoverrun.

3.6 CONNECTION OF SHIELDING GAS SUPPLY

The R-33-FM-580 Regulator-Flowmeter is designed foruse with an argon or argon-mix cylinder of shielding gas.It is adjustable for delivering up to 50 cfh through thetorch. To set up the system do the following:

Do Not adapt R-33-FM-580 for use with CO2. Reliefdevice may rupture if CO2 is used with the R-33-FM-580. For CO2 service, order R-33-FM-320, P/N 21558.

a. With the cylinder cap in place CAREFULLY slidethe cylinder of gas onto the Migmaster 250 cylinderrack.

b. Secure the cylinder to the unit, using the chainprovided.

c. Unscrew the cylinder cap.d. Open the cylinder valve slightly, just for an instant,

to blow away any dirt or dust which may have ac-cumulated in the cylinder valve outlet. Be sure tokeep your face away from the valve outletto protect your eyes.

e. Attach the regulator to the cylinder valve, tightenthe union nut securely with a 1-1/8in. open end oran adjustable wrench.

$�

Never stand directly in front of or behind the regula-tor when opening the cylinder valve. Always standto one side.

h. Using a leak test solution, such as P/N 998771 (8oz. container) or soapy water, test for leakageabout the cylinder valve stem, the regulator inletconnection, and the hose connections at the regu-lator and at the Migmaster 250 for leakage. Correctany leaks before starting work.

i. If work is to be stopped for a half-hour or more, orthe regulator is to be removed from the cylinder,shut down the regulator as follows:

a. Close the cylinder valve.

b. Release gas from the regulator by closing thetorch trigger lever.

c. When pressure gauge drops to zero, the regu-lator is de-pressurized and shutdown.

j. Each regulator is equipped with a porous metalinlet filter, P/N 71Z33, pressed into the regulatorinlet nipple. No. regulator should be connected toa cylinder or station valve unless it contains thisfilter. You can replace the filter if you have reasonto do so. To remove a filter refer to the regulatorinstruction literature for details.

k. Regulators in need of repair should be returned toyour Welding Equipment distributor or to an autho-rized Remanufacturing Center.

If welding is performed in a confined area, shieldinggas leaks could result in a buildup of shielding gasconcentration, displacing oxygen, thereby endan-gering personnel enter the area.

3.7 WELDING CABLE CONNECTIONS

Connect the work clamp solidly to the workpiece or worktable. Clamp onto a bare metal area.

A good electrical connection to the work is essentialto proper welding operation and to prevent electricshock.

Welding cables should be kept as short as possible andbe of adequate current carrying capacity. Resistance ofthe welding cables and connections causes a voltagedrop which is added to the voltage drop of the arc.Excessive cable resistance may result in a reduction ofthe maximum usable current output of the equipment.

The proper operation of this equipment is to a largeextent dependent on the use of welding cables andconnections which are in good condition and of adequatesize.

3.8 ASSEMBLE REAR WHEELS

The unit's running board is factory assembled except forthe rear wheels which are packed loose in the shippingcarton. The rear gear consists of 2-wheels, 4-washers,2-cotter pins, and an axle. To install the gear, do thefollowing:

a. Insert the axle through the holes provided at therear of the gear.

b. Place a washer onto each end of the axle, then slipon the wheels, then add another washer to theoutside of each wheel, and secure the whole as-sembly by inserting a pin in each end of the axle.

c. Remove the existing shipping supports by un-screwing from chassis.

3.9 INSTALLING OPTIONAL SPOT/STITCH/ANTI-STICK MODULE

a. Remove lower blank-cover plate from upper-rightfront panel of power supply -- save the four mount-ing screws.

b. Locate the harness-connected 15-pin plastic plug,P3, inside the mounting cavity. Note that this plugwill have a jumper plug with jumper wires con-nected to it -- remove (and save) the jumper plug.(The jumper plug must be reinstalled if the moduleis ever removed.

c. Connect the 15-pin plug into the matching recep-tacle on the rear of the optional control module. Theplug will only fit one way.

d. Install the control module in place of the blankpanel removed in Step a., using the same fourscrews that you saved.
