1-1 intROdUCtiOn

This equipment is intended for ultimate application by commercial/industrial users and for operation by persons trained and experienced in the use and maintenance of welding equipment. Operation should not be undertaken without adequate training in the use of such equipment. Training is available from many public and private schools or similar facilities.

Safe practices in the installation, operation and maintenance of this equipment requires proper training in the art, a careful study of the information provided with the equipment, and the use of common sense. Rules for safe use are generally provided by suppliers of welding power sources, compressed gas suppliers, and electrode suppliers. Careful compliance with these rules will promote safe use of this equipment.

The following Safety Rules cover some of the more generally found situations. READ

THEM CAREFULLY. In case of any doubt, obtain qualified help before proceeding.

1-2 GEnERaL PRECaUtiOnS a. Burn Prevention

ELECTRIC ARC WELDING PRODUCES

H I G H I N T E N S I T Y H E AT A N D

ULTRAVIOLET RADIANT ENERGY

WHICH MAY CAUSE SERIOUS AND

PERMANENT EYE DAMAGE AND

WHICH MAY DAMAGE ANY EXPOSED

SKIN AREAS.

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.

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 immediate treatment of flash burns 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 wear cuffless trousers to avoid entry of sparks and slag.

Avoid oily or greasy clothing. A spark may ignite them.

Flammable hair preparations should not be used by persons intending to weld or cut.

Hot metal such as electrode stubs and work pieces should never be handled without gloves.

Ear plugs should be worn when working on overhead or in a confined space. A hard hat should be worn when others work overhead.

B. toxic fume Prevention

WARNING: The use of this product may result in exposure to chemicals known to the State of California to cause cancer and birth defects or other reproductive harm.

Adequate ventilation. Severe discomfort, illness or death can result from fumes, vapors, heat, or oxygen enrichment or depletion that welding (or cutting) may produce. Prevent them with adequate ventilation. NEVER ventilate with oxygen.

Lead-, cadmium-, zinc-, mercury-, berylliumbearing and similar materials, when welded or cut, may produce 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 emit toxic fumes should not be heated unless coating is removed form the work surface, the area is well ventilated, or the operator wears an air-supplied respirator.

Work in a confined space only while it is being ventilated and, if necessary, while wearing an air-supplied respirator.

Gas leaks in a confined space should be avoided. Leaked gas in large quantities can change oxygen concentration 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 accidentally opened or left open.

Check to be sure that the space is safe before reentering it.

Vapors from chlorinated solvents can be decomposed by the heat of the arc (or flame) to form PHOSGENE, a highly toxic gas, and other lung and eye irritating products.

The ultraviolet (radiant) energy of the arc can also decompose trichloroethylene and perchloroethylene 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 perchloroethylene.

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 can fly many 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, ventilators. If the work cannot be moved, move combustibles at least 35 feet away, out of reach of sparks and heat; or protect against ignition with suitable and snugfitting, 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 extinguishing equipment during and for some time after welding or cutting if:

1. Appreciable combustibles (including building construction) are within 35 feet.

2. Appreciable combustibles are further than 35 feet, but can be ignited by sparks.

3. Openings (concealed or visible) in floors or walls within 35 feet may expose combustibles to sparks.

4. Combustibles 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 never be welded on or cut, unless container has first been cleaned in accordance with industry standards.

This includes: a thorough steam or caustic cleaning (or a solvent of water washing, depending on the combustible’s solubility), followed by purging and inerting with nitrogen or carbon dioxide, and using protective equipment.

Water-filling just below working level may substitute for inerting.

Weld Control Selector Guide - Page i


- Continued -

A container with unknown contents should be cleaned (see paragraph above). Do

NOT depend on sense of smell or sight to determine if 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

The safe handling of compressed gas equipment is detailed in numerous industry publications. The following general rules cover many of the most common situations.

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 faulty 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 including third rails, electrical wires, or welding circuits. They can produced 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 of 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 stuck.

Transporting cylinders. With a crane, use a secure support such as a platform or cradle. 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 55 degrees C (130 degrees F.) Cool with water spray where such exposure exists.

Protect cylinders, particularly valves from bumps, falls, falling objects, and weather.

Replace caps securely when moving cylinders.

Stuck valve. Do NOT use a hammer or wrench to open a cylinder valve that cannot 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 exchanged.

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 ferrules or clamps designed for the hose

(not ordinary wire or other substitute) as a binding to connect hoses to fittings.

No copper tubing splices. Use only standard brass fittings 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 tangles.

Protect hose from damage by sharp edges, and by sparks, slag, and open flame.

Examine hose regularly for leaks, wear, and loose connections. Immerse pressured hose in water; bubbles indicate leaks

Repair leaky or worn hose by cutting area out and splicing. 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, lintless cloth.

Match regulator to cylinder. Before connecting, check that the regulator label and cylinder marking agree, and that the regulator inlet and

Weld Control Selector Guide - Page ii 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 connections, clean and smooth seats where necessary. Tighten. If connection leaks, disassemble, clean, and retighten, using properly fitting wrench.

Adapters. Use a CGA adapter (available from your supplier) between cylinder and regulator, if one is required. Use two wrenches to tighten adapter marked RIGHT and LEFT HAND threads.

Regulator outlet (or hose) connections may be identified 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 excessive 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 increases 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 shut-off.

Use pressure charts (available from your supplier) for safe and efficient recommended pressure settings on regulators.

Check for leaks on first pressurization and regularly thereafter. Brush with soap solution. Bubbles indicate leaks. Clean off soapy water after test; dried soap is combustible.

E. User Responsibilities

Follow all Safety Rules.

Remove leaky or defective equipment from service immediately for repair. Read and follow user manual instructions.

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


- Continued very bright and hot. Sparks fly, fumes rise, ultraviolet and infrared energy radiates, weldments are hot, and compressed gases may be used. The wise operator avoids unnecessary risks and protects himself and others from accidents.

a. Burn Protection

Comply with precautions in 1-2.

The welding arc is intense and visibly bright. Its radiation 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 PRECAUTIONS.

1. Protective Clothing

Wear long-sleeve clothing in addition to gloves, hat, and shoes. As necessary, use additional protective clothing such as leather jacket or sleeves, flameproof apron, and fire-resistant leggings. Avoid outer garments 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. Eyes may be damaged by radiant energy when exposed to the electric arc, even when not looking in the direction of the 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.

Protect filter plate with a clear cover plate.

Cracked or broken helmet or shield should

NOT be worn; radiation can be passed 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 to give some protection to the eyes should the helmet not be lowered over the face before an arc is struck. Looking 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

Enclose the welding area. For production welding, a separate room or enclosed bay is best. In open areas, surround the operation with low-reflective, noncombustible screens or panels. Allow for free air circulation, particularly at floor level.

Viewing the weld. Provide face shields for all persons who will be looking 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

Comply with precautions in 1-2C.

Equipment’s rated capacity. Do not overload arc welding equipment. It may overheat cables and cause a fire.

Loose cable connections may overheat or flash and cause afire.

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 electrically 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 dampness or sweat cannot 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 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 currents may shock, possibly fatally. Do NOT GROUND to electrical conduit, or to a pipe carrying ANY gas or a flammable liquid such as oil or fuel.

Three-phase connection. Check phase requirement of equipment before installing. If only three-phase power is available, connect single-phase equipment to only two wires of the three-phase line. Do NOT connect the equipment ground lead to the third (live) wire, or the equipment will become electrically

HOT - a dangerous condition that can shock, possibly fatally.

Before welding, check ground for continuity.

Be sure conductors are touching bare metal of equipment frames at connections.

If a line cord with a ground lead is provided with the equipment for connection to a switch box, connect the ground lead to the grounded switch box. If a three-prong plug is added for connection to a grounded mating receptacle, the ground lead must be connected to the ground prong only. If the line cord comes with a three-prong plug, connect to a grounded mating receptacle.

Never remove the ground prong from a plug, or use a plug with a broken ground prong.

2. Connectors

Fully insulated lock-type connectors should be used to join welding cable lengths.

3. 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.

4. terminals and Other Exposed Parts

Terminals and other exposed parts of electrical units should have insulating covers secured before operation.

5. Electrode Wire

Electrode wire becomes electrically HOT when the power switch of gas metal-arc welding equipment is ON and welding gun trigger is pressed. Keep hands and body clear of wire and other HOT parts.

6. Safety devices

Safety devices such as interlocks and circuit breakers should not be disconnected or shunted out.

Before installation, inspection, or service of equipment, shut OFF all power, and remove line fuses (or lock or red-tag switches) to prevent accidental turning ON of power.

Disconnect all cables from welding power source, and pull all 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. Always shut OFF, and disconnect all power to equipment.

Power disconnect switch must be available near the welding power source.

Weld Control Selector Guide - Page iii

aBOUt tHiS GUidE

This Weld Control Selector Guide is designed to aid in selection and installation of various weld controls and

Cobramatic feeders. The most popular power supplies from various manufacturers are covered, however, many others are not. The power supplies not covered in this guide can also be hooked up to Cobramatic feeders by modifying the connections. Spool-guns may also be hooked up by using a WC-1 control box.

The exception to this is "synergic" type of power supplies. There are two types of "synergic" units. If the controls for the power supply are on the power supply, then a Cobramatic II feeder may be adaptable. If the controls for the power supply are incorporated into that manufacturers wire feeder, then it becomes difficult to hook up a different type of feeder.

CAUTION :

When working with voltages present in this product and others, always observe warning and caution signs. Service must only be performed by qualified service personnel.

diSCLaiMER

At the time of its printing the information in this guide was accurate according to the information provided by the various manufacturers. Due to model variations, modifications and other unknowns, this information may not be accurate in all cases. Refer to the power supply owner's manual if there are any questions

or doubts about proper hook-up. Upon using this guide the user accepts full responsibility of the consequences that may occur during hook-up. All work should only be attempted by a qualified service technician with the proper tools and knowledge of electronics.

WHy dO i nEEd a WELd COntROL?

The weld control provides the electronics needed to operate the spool gun, as well as, provide the contactor signal to activate the power supply. In a GMAW (MIG) system the wire is not electrically hot until the weldor activates the trigger. The weld control then sends the contactor signal to energize the power supply.

There are two types of contactor signals that various power supply manufacturers use. The first is a "Closing

Contact" signal. With this type of signal the weld control simply touches the two contactor leads together

(providing continuity to the power supply). The second type of signal is the "115VAC" signal. With this type of signal the weld control sends 115 volts AC to the power supply. If you were to touch the contactor leads in this position, you would get a SHOCK when the trigger is activated. All GTAW (TIG) machines use a closing contact signal because it would be unsafe to put a 115VAC contactor signal in a foot control.

WHiCH WELd COntROL?

The WC-1 can be used on all power supplies, although it may not be the most economical or most feasible approach. Where possible, a dedicated weld control has been developed to simplify installation and lower cost. These controls interface to a particular power supply or a group of power supplies from a certain manufacturer.

HOW tO USE tHiS GUidE

1. Using the charts on pages 1 thru 5, locate the power supply you wish to connect to.

2. The next column over will indicate which control is needed for the Prince XL Spool-gun. Sometimes, an optional control is available. This will be indicated in the third column. The fourth column will list any special notes. note: for Cobramatic feeders a weld control is not needed, however, if a contactor box is listed it should be used.

3. Check the notes column for important information.

4. Check the hook-up instructions column for the section, then go to that section.

5. The Posa Start on the Cobramatic feeders can be used with all CV/CC power supplies by simply connecting the single black lead extending from the back of the unit to work ground (-).

6. Reference the appendix for connection information to many utility type welders.

notes:

1. Miller power supply must have 14 pin Amphenol or the WC-1 must be used. See WC-1 hookup, section M-2.

2. Constant current (CC) power supplies can only be used in spray transfer mode with

ALUMINUM and CORED wire only.

3. These power supplies put out less than 24VAC to the spool gun therefore maximum speed will not be obtained. This means 3/64 diameter wire should be used when welding materials thicker than 1/4.

4. Must be used in the non "synergic" mode.

5. Contactor box not needed if power supply has optional remote control facilities (panel).

6. WC-1 Weld Control can also be used.

7. An adapter cable with Amphenol already attached can be used with the power supply and

WC–1 or Cobramatic combination.

8. Many of the newer power supplies, especially the inverter style units now use a Dinse style connector for the weld power out. This means the lug on the power cable of the Spool-gun must be cut-off and replaced by a male Dinse connector (MK P/N: 153-0755).

9. MK does not make a weld control for the Lincoln PowerMig 255. Since Lincoln makes their own control for a Prince XL Spool-gun, they furnish the control module with the Spool-gun.

However the WC-1 or the MK Cobramatic Cabinet may be used with that unit (See L-7 ).

10. At this time, the Lincoln Commander 300 and 500 does not have 42VAC volts at the 14-Pin connector. An optional kit (P/N: K1597-1) must be obtained from Lincoln in order to use the

Prince ® XL spool gun with the PA-L1. Units with a date code of November 2001 have 42VAC.

11. If the Fabricator 210 has a 4 digit specification number (xxxx), then the 14-Pin Control will work. If the 4 digit specification has an "A" at the end (xxxxA), then a WC-1 Control must be used. (See H-2)

12. To use an MK 003-1341 Adapter, the Multimaster 260 requires the optional ESAB spool gun control module. Units after S/N 0558001793 come standard with the Spool Gun Module.

13. The Classic Series engine driven welder is a CC type power supply. To properly operate this unit while welding aluminum, the CV tap is required. However, because 42VAC is unavailable a WC-1 Weld Control must be used.

Since Hobart was divided up and sold to several different companies; the type of interfacing plug might be different depending on the age of the machines. At one time Hobart put both a 5-Pin and a 19-Pin

Amphenol on their units. Then they went strictly to a 5-Pin Amphenol. As other companies came into the picture, some introduced the Miller version of a 14-P Amphenol. Then on some models, both a 5-Pin and a 14-Pin were used. To add to the confusion, some later models have both a 14-Pin and a 19-Pin

Amphenol (The Fabstar is a good example of this). The one constant seems that all of these amphenols used CLOSING CONTACTS to pins A and B. Check each particular machine to see what type of amphenol is used. If there are any questions, refer to the machine's Owners Manual and/or check for voltages with a V-O-M. (Volt-Ohmmeter)

POSaStaRt COnnECtiOnS

The Cobramatic and Cobra II Wire Feeders each have, a single black 14 ga. wire with an alligator clip, extending from the back connected to the main board. This is the voltage sensing lead for the PosaStart circuit. In order for PosaStart to properly work, this lead must be connected to the welding GROUND.

Typically, most power supplies will accept the PosaStart lead connected to either the work GROUND lug on their front panel or the

GROUND clamp.

However, some newer types of inverters must have this PosaStart lead connected directly to the GROUND lug.

Newer Cobramatic units have a CC/CV configuration switch on the main board. Consult the owners manual in order to properly configure this switch.

Contactor Selection

There are two types of contactor signals that various power supply manufacturers use. A "Closing Contact or Contactor" and a “115VAC Contactor” signal. Once the power supply contactor is closed, the welding leads become electrically live and are referred to as being “live” or “hot”.

For the Closing Contactor type, the weld control simply touches the two contactor leads together (providing a continuity signal to the power supply) like a light switch. ALL Cobramatic wire feeders and Weld Controls are shipped in this configuration (Figure A). Since no voltage is applied to the leads in tis configuration, it is safe to handle and there is no risk of personal injury from electrocution.

UtiLity StyLE WELdERS

There are many other welders made by companies like CK Systematics, Century

Manufacturing, and some foreign manufactured machines that are capable of welding aluminum, utilizing the Cobramatic system or Prince XL Spool Guns.

These units can usually be broken down into two categories.

1. A utility MIG welder with the wire feeder built into the unit.

These units need to be in 200 to 275 amp range and operate from 208/230/460 Volts

2. A CC/CV Power supply capable of accepting a wire feeder.

(These units are usually 3-Phase).

Units in the second category usually have some sort of connector for the wire feeder that needs to be identified by model and pin configuration. Then an adapter pigtail may be made that will interconnect with these units.

Units in the first category are a little more difficult. There’s usually no internal or external hookup for a secondary wire feed system; 115VAC must be derived from a secondary source (i.e. extension cord from a wall outlet) to run the

Cobramatic system or a Prince XL Spool Gun with a WC-1 Control Box. What becomes difficult is “How to trigger the contactor?”

If the trigger leads from the units are accessible, then the contactor leads from the Cobra Cabinet or the WC-1 Control Box may be spliced to these leads

(Cobra or WC-1 must be in “Closing Contacts” mode). However, this will also trigger the units internal welder, so care must be taken to loosen the idler roll on the unit’s internal wire feeder so that it does not feed wire while welding with the Cobramatic Cabinet or Spool Gun.

Sometimes the most difficult thing to locate is the source of welding current.

There has to be a cable going to the unit’s internal wire feeder. A connection can usually be made to one of the ends of this cable to the Spool Gun.

A Cobramatic Cabinet or a WC-1 Control for the Prince XL Spool Gun may be hooked up to many other MIG welders beside those listed on the previous pages.

In some cases, the size and output of many of the smaller units, especially those that operate on 115VAC only, do not lend themselves to an efficient arc.

Examples of these are the Lincoln SP125, the Millermatic 130XP, and the Hobart

Handler. These units only deliver 18-19 Open Circuit Volts (max). Since welding on 1/8" thick aluminum requires 100 to 120 amps at 20 to 21 volts, the welds are marginal at best.
