ELECTRIC SHOCK can kill.

3.a. The electrode and work (or ground) circuits are electrically “hot” when the welder is on. Do not touch these “hot” parts with your bare

gloves to insulate hands.

3.b. Insulate yourself from work and ground using dry insulation. Make certain the insulation is large enough to cover your full area of physical contact with work and ground.

In addition to the normal safety precautions, if welding must be performed under electrically hazardous conditions (in damp locations or while wearing wet clothing; on metal structures such as floors, gratings or scaffolds; when in cramped positions such as sitting, kneeling or lying, if there is a high risk of unavoidable or accidental contact with the workpiece or ground) use the following equipment:

• Semiautomatic DC Constant Voltage (Wire) Welder.

• DC Manual (Stick) Welder.

• AC Welder with Reduced Voltage Control.

3.c. In semiautomatic or automatic wire welding, the electrode, electrode reel, welding head, nozzle or semiautomatic welding gun are also electrically “hot”.

3.d. Always be sure the work cable makes a good electrical connection with the metal being welded. The connection should be as close as possible to the area being welded.

3.e. Ground the work or metal to be welded to a good electrical (earth) ground.

3.f.

Maintain the electrode holder, work clamp, welding cable and welding machine in good, safe operating condition. Replace damaged insulation.

3.g. Never dip the electrode in water for cooling.

3.h. Never simultaneously touch electrically “hot” parts of electrode holders connected to two welders because voltage between the two can be the total of the open circuit voltage of both welders.

3.i. When working above floor level, use a safety belt to protect yourself from a fall should you get a shock.

ARC RAYS can burn.

4.a. Use a shield with the proper filter and cover plates to protect your eyes from sparks and the rays of the arc when welding or observing open arc welding. Headshield and filter lens should conform to ANSI Z87. I standards.

4.b. Use suitable clothing made from durable flame-resistant material to protect your skin and that of your helpers from the arc rays.

4.c. Protect other nearby personnel with suitable, non-flammable screening and/or warn them not to watch the arc nor expose themselves to the arc rays or to hot spatter or metal.

FUMES AND GASES can be dangerous.

5.a. Welding may produce fumes and gases hazardous to health. Avoid breathing these fumes and gases.When welding, keep your head out of the fume. Use enough

fumes and gases away from the breathing zone. When

welding with electrodes which require special ventilation such as stainless or hard facing (see instructions on container or MSDS) or on lead or cadmium plated steel and other metals or coatings which produce highly toxic fumes, keep exposure as low as possible and below Threshold Limit Values (TLV) using local exhaust or mechanical ventilation. In confined spaces or in some circumstances, outdoors, a respirator may be required. Additional precautions are also required when welding on galvanized steel.

5. b. The operation of welding fume control equipment is affected by various factors including proper use and positioning of the equipment, maintenance of the equipment and the specific welding procedure and application involved. Worker exposure level should be checked upon installation and periodically thereafter to be certain it is within applicable OSHA PEL and ACGIH TLV limits.

5.c.

Do not weld in locations near chlorinated hydrocarbon coming from degreasing, cleaning or spraying operations. The heat and rays of the arc can react with solvent vapors form phosgene, a highly toxic gas, and other irritating products.

WELDING and CUTTING SPARKS can cause fire or explosion.

6.a.

Remove fire hazards from the welding area.

If this is not possible, cover them to prevent

Remember that welding sparks and hot materials from welding can easily go through small cracks and openings to adjacent areas. Avoid welding near hydraulic lines. Have a fire extinguisher readily available.

6.b. Where compressed gases are to be used at the job site, special precautions should be used to prevent hazardous situations. Refer to “Safety in Welding and Cutting” (ANSI Standard Z49.1) and the operating information for the equipment being used.

6.c. When not welding, make certain no part of the electrode circuit is touching the work or ground. Accidental contact can cause overheating and create a fire hazard.

6.d. Do not heat, cut or weld tanks, drums or containers until the proper steps have been taken to insure that such procedures will not cause flammable or toxic vapors from substances inside. They can cause an explosion even been “cleaned”. For information, purchase “Recommended Safe Practices for the Containers and Piping That Have Held Hazardous Substances”, AWS F4.1 from the American Welding Society

(see address above).

6.e. Vent hollow castings or containers before heating, cutting or welding. They may explode.

Sparks and spatter are thrown from the welding arc. Wear oil

6.f. free protective garments such as leather gloves, heavy shirt, cuffless trousers, high shoes and a cap over your hair. Wear ear plugs when welding out of position or in confined places. Always wear safety glasses with side shields when in a welding area.

6.g. Connect the work cable to the work as close to the welding area as practical. Work cables connected to the building framework or other locations away from the welding area increase the possibility of the welding current passing through lifting chains, crane cables or other alternate circuits. This can create fire hazards or overheat lifting chains or cables until they fail.

PRÉCAUTIONS DE SÛRETÉ

Pour votre propre protection lire et observer toutes les instructions et les précautions de sûreté specifiques qui parraissent dans ce manuel aussi bien que les précautions de sûreté générales suivantes:

Sûreté Pour Soudage A LʼArc

1. Protegez-vous contre la secousse électrique:

a. Les circuits à lʼélectrode et à la piéce sont sous tension

quand la machine à souder est en marche. Eviter toujours tout contact entre les parties sous tension et la peau nue ou les vétements mouillés. Porter des gants secs et sans trous pour isoler les mains.

b. Faire trés attention de bien sʼisoler de la masse quand on

soude dans des endroits humides, ou sur un plancher metallique ou des grilles metalliques, principalement dans

les positions assis ou couché pour lesquelles une grande partie du corps peut être en contact avec la masse.

c. Maintenir le porte-électrode, la pince de masse, le câble

de soudage et la machine à souder en bon et sûr état defonctionnement.

d.Ne jamais plonger le porte-électrode dans lʼeau pour le

refroidir.

e. Ne jamais toucher simultanément les parties sous tension

des porte-électrodes connectés à deux machines à souder parce que la tension entre les deux pinces peut être le total de la tension à vide des deux machines.

f. Si on utilise la machine à souder comme une source de

courant pour soudage semi-automatique, ces precautions pour le porte-électrode sʼapplicuent aussi au pistolet de soudage.

5. Toujours porter des lunettes de sécurité dans la zone de soudage. Utiliser des lunettes avec écrans lateraux dans les zones où lʼon pique le laitier.

6. Eloigner les matériaux inflammables ou les recouvrir afin de prévenir tout risque dʼincendie dû aux étincelles.

7. Quand on ne soude pas, poser la pince à une endroit isolé de la masse. Un court-circuit accidental peut provoquer un échauffement et un risque dʼincendie.

8. Sʼassurer que la masse est connectée le plus prés possible de la zone de travail quʼil est pratique de le faire. Si on place la masse sur la charpente de la construction ou dʼautres endroits éloignés de la zone de travail, on augmente le risque de voir passer le courant de soudage par les chaines de levage, câbles de grue, ou autres circuits. Cela peut provoquer des risques dʼincendie ou dʼechauffement des chaines et des câbles jusquʼà ce quʼils se rompent.

9. Assurer une ventilation suffisante dans la zone de soudage. Ceci est particuliérement important pour le soudage de tôles galvanisées plombées, ou cadmiées ou tout autre métal qui produit des fumeés toxiques.

10. Ne pas souder en présence de vapeurs de chlore provenant dʼopérations de dégraissage, nettoyage ou pistolage. La chaleur ou les rayons de lʼarc peuvent réagir avec les vapeurs du solvant pour produire du phosgéne (gas fortement toxique) ou autres produits irritants.

11. Pour obtenir de plus amples renseignements sur la sûreté, voir le code “Code for safety in welding and cutting” CSA Standard W 117.2-1974.

2. Dans le cas de travail au dessus du niveau du sol, se protéger contre les chutes dans le cas ou on recoit un choc. Ne jamais enrouler le câble-électrode autour de nʼimporte quelle partie du corps.

3. Un coup dʼarc peut être plus sévère quʼun coup de soliel, donc:

a. Utiliser un bon masque avec un verre filtrant approprié

ainsi quʼun verre blanc afin de se protéger les yeux du rayonnement de lʼarc et des projections quand on soude ou quand on regarde lʼarc.

b. Porter des vêtements convenables afin de protéger la

peau de soudeur et des aides contre le rayonnement de lʻarc.

c. Protéger lʼautre personnel travaillant à proximité au

soudage à lʼaide dʼécrans appropriés et non-inflammables.

4. Des gouttes de laitier en fusion sont émises de lʼarc de soudage. Se protéger avec des vêtements de protection libres de lʼhuile, tels que les gants en cuir, chemise épaisse, pantalons sans revers, et chaussures montantes.

EX350ie (CE) (RED-D-ARC)

PRÉCAUTIONS DE SÛRETÉ POUR LES MACHINES À SOUDER À TRANSFORMATEUR ET À REDRESSEUR

1. Relier à la terre le chassis du poste conformement au code de lʼélectricité et aux recommendations du fabricant. Le dispositif de montage ou la piece à souder doit être branché à une bonne mise à la terre.

2. Autant que possible, Iʼinstallation et lʼentretien du poste seront effectués par un électricien qualifié.

3. Avant de faires des travaux à lʼinterieur de poste, la debrancher à lʼinterrupteur à la boite de fusibles.

4. Garder tous les couvercles et dispositifs de sûreté à leur place.

SAFETY

Electromagnetic Compatibility (EMC)

Conformance Products displaying the CE mark are in conformity with European Community Council Directive of 3 May 1989 on the approximation of the laws of the Member States relating to electromagnetic compatibility (89/336/EEC). It was manufactured in conformity with a national standard that implements a harmonized standard: EN 60974-10 Electromagnetic Compatibility (EMC) Product Standard for Arc Welding Equipment. It is for use with other Lincoln Electric equipment. It is designed for industrial and professional use.

Introduction All electrical equipment generates small amounts of electromagnetic emission. Electrical emission may be transmitted through power lines or radiated through space, similar to a radio transmitter. When emissions are received by other equipment, electrical interference may result. Electrical emissions may affect many kinds of electrical equipment; other nearby welding equipment, radio and TV reception, numerical controlled machines, telephone systems, computers, etc. Be aware that interference may result and extra precautions may be required when a welding power source is used in a domestic establishment.

Installation and Use The user is responsible for installing and using the welding equipment according to the manufacturerʼs instructions. If electromagnetic disturbances are detected then it shall be the responsibility of the user of the welding equipment to resolve the situation with the technical assistance of the manufacturer. In some cases this remedial action may be as simple as earthing (grounding) the welding circuit, see Note. In other cases it could involve construction of an electromagnetic screen enclosing the power source and the work complete with associated input filters. In all cases electromagnetic disturbances must be reduced to the point where they are no longer troublesome.

v

Note: The welding circuit may or may not be earthed for safety reasons according to national codes.

Changing the earthing arrangements should only be authorized by a person who is competent to access whether the changes will increase the risk of injury, e.g., by allowing parallel welding current return paths which may damage the earth circuits of other equipment.

Assessment of Area Before installing welding equipment the user shall make an assessment of potential electromagnetic problems in the surrounding area. The following shall be taken into account:

a) other supply cables, control cables, signaling and telephone cables; above, below and adjacent to the

welding equipment;

b) radio and television transmitters and receivers;

c) computer and other control equipment;

d) safety critical equipment, e.g., guarding of industrial equipment;

e) the health of the people around, e.g., the use of pacemakers and hearing aids;

f) equipment used for calibration or measurement

g) the immunity of other equipment in the environment. The user shall ensure that other equipment being

used in the environment is compatible. This may require additional protection measures;

h) the time of day that welding or other activities are to be carried out.

SAFETY

Electromagnetic Compatibility (EMC)

The size of the surrounding area to be considered will depend on the structure of the building and other activities that are taking place. The surrounding area may extend beyond the boundaries of the premises.

Methods of Reducing Emissions

Mains Supply Welding equipment should be connected to the mains supply according to the manufacturerʼs recommendations. If interference occurs, it may be necessary to take additional precautions such as filtering of the mains supply. Consideration should be given to shielding the supply cable of permanently installed welding equipment, in metallic conduit or equivalent. Shielding should be electrically continuous throughout its length. The shielding should be connected to the welding power source so that good electrical contact is maintained between the conduit and the welding power source enclosure.

Maintenance of the Welding Equipment The welding equipment should be routinely maintained according to the manufacturerʼs recommendations. All access and service doors and covers should be closed and properly fastened when the welding equipment is in operation. The welding equipment should not be modified in any way except for those changes and adjustments covered in the manufacturers instructions. In particular, the spark gaps of arc striking and stabilizing devices should be adjusted and maintained according to the manufacturerʼs recommendations.

vi

Welding Cables The welding cables should be kept as short as possible and should be positioned close together, running at orclosetofloorlevel.

Equipotential Bonding Bonding of all metallic components in the welding installation and adjacent to it should be considered. However, metallic components bonded to the work piece will increase the risk that the operator could receive a shock by touching these metallic components and the electrode at the same time. The operator should be insulated from all such bonded metallic components.

Earthing of the Workpiece Where the workpiece is not bonded to earth for electrical safety, not connected to earth because of its size and position, e.g., ships hull or building steelwork, a connection bonding the workpiece to earth may reduce emissions in some, but not all instances. Care should be taken to prevent the earthing of the workpiece increasing the risk of injury to users, or damage to other electrical equipment. Where necessary, the connection of the workpiece to earth should be made by a direct connection to the workpiece, but in some countries where direct connection is not permitted, the bonding should be achieved by suitable capacitance, selected according to national regulations.

Screening and Shielding Selective screening and shielding of other cables and equipment in the surrounding area may alleviate problems of interference. Screening of the entire welding installation may be considered for special applications. 1

INSTALLATION

SAFETY PRECAUTIONS

WARNING

ELECTRIC SHOCK can kill.

• TURN THE INPUT POWER OFF AT THE DISCONNECT SWITCH BEFORE ATTEMPTING TO CONNECT OR DIS-

CONNECT INPUT POWER LINES, OUTPUT CABLES, OR CONTROL CABLES.

• Only qualified personnel should perform this installation.

• Connect the green/yellow lead of the power cord to ground per appropriate National Electrical Code.

----------------------------------------------------------------------

SELECT SUITABLE LOCATION

The EX350ie (CE) will operate in harsh environments. Even so, it is important that simple preventative measures are followed in order to assure long life and reliable operation.

• The machine must be located where there is free circulation of clean air such that air movement in the back, out the sides and bottom will not be restricted.

• Dirt and dust that can be drawn into the machine should be kept to a minimum. Failure to observe these precautions can result in excessive operating temperatures and nuisance shutdown.

• Keep machine dry. Shelter from rain and snow. Do

not place on wet ground or in puddles.

CAUTION

• DO NOT MOUNT OVER COMBUSTIBLE SURFACES.

Where there is a combustible surface directly under stationary or fixed electrical equipment, that surface shall be covered with a steel plate at least .06”(1.6mm) thick, which shall extend not less than 5.90”(150mm) beyond the equipment on all sides.

------------------------------------------------------------------------

STACKING

EX350ie (CE) cannot

TILTING

Place the machine directly on a secure, level surface or on a recommended undercarriage. The machine may topple over if this procedure is not followed.

INPUT AND GROUNDING CONNECTIONS

• Only a qualified electrician should connect the

EX350ie (CE). Installation should be made in accordance with the appropriate National Electrical Code, all local codes and the information detailed below.

• When received directly from the factory, multiple

voltage machines are internally connected for 440VAC. If 440VAC is the desired input, then the machine may be connected to the power system without any setup required inside the machine.

be stacked.

A-2

• Initial 200VAC - 415VAC operation will require an Input voltage panel setup.

• Open the access panel on the rear of the machine.

•

For 200 or 230: Position the large switch to 200-230. For higher voltages: Position the large switch to ≥ 380.

• Move the "A" lead to the appropriate terminal.

POWER CORD CONNECTION

A 5 meter power cord is wired into the machine. Follow the power cord connection instructions.

CAUTION

• Incorrect connection may result in equipment damage.

PARALLEL OPERATION

The EX350ie (CE) are operable in parallel in CC mode. For best results, the currents of each machine should be reasonably well shared. As an example, with two machines set up in parallel for a 400 amp procedure, each machine should be set to deliver approximately 200 amps, not 300 amps from one and 100 amps from the other. This will minimize nuisance shutdown conditions. In general, more than two machines in parallel will not be effective due to the voltage requirements of procedures in that power range.

To set machine outputs, start with output control pots and arc control pots in identical positions. Use the output control pots to balance the currents and maintain the desired current. The arc control pots should be kept identical on the two machines.

5. THERMAL

• This status light indicates when the power source has been driven into thermal overload. If the output terminals were "ON", the "ON" light will blink indicating that the output will be turned back on once the unit cools down to an acceptable temperature level. If the unit was operating in the "REMOTE" mode, the trigger will need to be opened before or after the thermal has cleared and closed after the machine has cooled down to an acceptable temperature to establish output.

6. CONTROL-REMOTE , LOCAL

• Two status lights indicate the location of output control as pre-determined by the power sources auto-configure system.

• The LOCAL display will be lit when control is at the power source.

• The REMOTE display will be lit when a remote pot/control is detected.

These Output Control configurations can be overridden (switched) with the CONTROL push button. When changed, the unit will power up in the configuration it was in when it was last powered down.

B-2

CC-STICK SOFT: The Stick Soft process features

continuous control ranging from 5 to 425 amps. This mode was intended for most SMAW applications, and Arc Gouging.

• Arc Gouging: Setting the output of the Stick Soft mode to 425 amps and/or setting the arc control to

9.5 or above will enable the arc-gouging mode. The actual output current will depend on the size of carbon used. The recommended maximum size carbon is 5/16"(7.9mm).

• The Hot Start control regulates the starting current at arc initiation. Hot Start can be adjusted from minimum (0), with no additional current added at arc start, to maximum (10), with double the preset current or 425 amps (max of machine) added for the first second after arc initiation.

• The Arc Control regulates the Arc Force to adjust the short circuit current. The minimum setting (-10) will produce a "soft" arc and will produce minimal spatter. The maximum setting (+10) will produce a "crisp" arc and will minimize electrode sticking.

CC-STICK CRISP: The Stick Crisp mode features continuous control from 5 to 425 amps. This mode was intended primarily for pipe welding applications.

Hidden Middle Control Panel – Process Set Up Panel

The middle control panel is removable to allow for upgrades (see Field Installed Options/Accessories).

• The Arc Control regulates the Arc Force to adjust the short circuit current. The minimum setting (-10) will produce a "soft" arc and will produce minimal spatter. The maximum setting (+10) will produce a "crisp" arc and will minimize electrode sticking.

TIG GTAW: The TIG mode features continuous control from 5 to 425 amps. The TIG mode can be run in either the TIG touch start or high frequency assisted start mode.

• The Hot Start control selects the starting mode

desired. A setting of less than 5, the TIG lift start mode is selected. The OCV is controlled below 10v and the short circuit "TIG touch" current is maintained at 25 amps independent of the preset current. When the tungsten is lifted, an arc is initiated and the output is regulated at the preset value. Hot start settings between 0 and 5 regulate the arc initiation current. A setting of 5 results in the most positive arc initiation. A setting of 0 reduces hot start.

• Hot Start settings between 5 and 10, select high fre-

quency assisted starting TIG mode. In this range, the OCV of the machine is controlled between 50 and 70 volts. If using the Lincoln K930-1 TIG Module, set the Hot start to 10 for maximum OCV.

• The Arc Control is not used in the TIG mode.

OPERATION

B-3

CV-INNERSHIELD: The CV-INNERSHIELD mode

features continuous control from 10 to 45 volts. This mode was designed for self-shielded flux cored wires that require tight voltage control.

• The Hot Start control is not used in the CV-FLUX CORED mode.

• The Arc Control regulates pinch effect. At the minimum setting (-10), minimizes pinch and results in a soft arc. At the maximum setting (+10), maximizes pinch effect and results in a crisp arc. Most selfshielded wires work well at an Arc Control setting of 5.

8. HOT START and ARC CONTROL features have

different functions depending on the welding Mode that is active. Each feature is described under the welding mode heading. (See Item 6 for specified

Mode Operation)

LOWER CASE FRONT

The output studs, line switch and remote connector are located on the lower case front.

9. Both STUDS contain "Twist-Mate" connector

inserts.

• The Negative stud is configured to accept the pass through gas system.

TIG SOLENOID OPTION

The Solenoid only operates when the EX350ie (CE) is in the TIG mode. If the Weld Terminals are in “Remote” then the solenoid will open when the arc start switch is closed. The solenoid will close after the arc switch has been opened and the post flow time expired.

If the Weld Terminals are turned “ON”, then the solenoid will open when the electrode is touch to the work. The electrode needs to remain in contact with the work to allow for gas coverage before attempting to start the arc. The solenoid will close after the arc has been broken and the post flow time expired.

CV-WIRE: The CV-WIRE mode features continuous control from 10 to 45 volts. The mode was intended for most GMAW, FCAW, and MCAW applications.

• The Hot Start control is not used in the CV-WIRE mode.

• The Arc Control regulates pinch effect. At the minimum setting (-10), minimizes pinch and results in a soft arc. Low pinch settings are preferable for welding with gas mixes containing mostly inert gases. At the maximum setting (+10), maximizes pinch effect and results in a crisp arc. High pinch settings are prefer-

If after connecting or removing a remote, the EX350ie (CE) did not configured the way you would like the local or remote control settings can be changed by pushing the OUTPUT CONTROL or WELD TERMINAL button. (A user cannot select between the 6 and 14-pin MS-style connector.)

CV modes

• The remote will default to the 14-pin MS-style connector remote if a remote is connected. If no remote is connected to the 14-pin MS-style connector then the remote will default to the 6-pin MS-style connector if a remote is connected to it.

• In all of the CV modes, the WELD TERMINAL control will default to REMOTE.

B-4

TIG mode

• The remote will default to the 6-pin MS-style if a remote control is connected to the 6-pin MS-style and to the 14-pin MS-style connectors. If a remote is not connected to the 6-pin MS-style connector then the remote will default to the 14-pin MS-style connector if a remote is connected.

• If a remote control is connected to any of the amphenols the WELD TERMINAL control will default to REMOTE. If there are not any remote control devices attached the WELD TERMINAL control will default to ON.

OPERATION

B-4

Types of Remote WELD TERMINAL Control

• The EX350ie (CE) Weld Terminals can be controlled from each of the amphenol connectors. The circuit has a nominal OCV of 15VDC and requires a dry contact closure (less than 100 ohms) to activate the output of the EX350ie (CE).

• 14 Pin Amphenols the Weld Terminals are controlled from pins C (lead 2) and pin D (lead 4). Pin C is positive.

• 6 Pin Amphenol the Weld Terminals are controlled from pin D (lead 2) and pin E (lead 4). In the 6-pin amphenol pin D is positive.

CC-Stick modes

• The remote will default to only the 6-pin amphenol if a remote is connected to it.

• The WELD TERMINAL control will default to ON with or without a remote connected.

Types of Remote OUTPUT CONTROL

• The EX350ie (CE) Output Control can be controlled by either a potentiometer connected between 77 & 75 with the wiper connected to 76 or a 0V to 10V DC supply connected between 76 & 75. (76 needs to be positive)

• 14-pin MS-style connector lead 75 is pin G, lead 76 is pin F and lead 77 is pin E.

• 6-pin MS-style connector lead 75 is pin C, lead 76 is pin B and lead 77 is pin A.

Potentiometer Control

• The total resistance should be between 2000 ohms (2K) and 10,000 ohms (10K)

• The machine output will be at minimum when lead 76 (wiper) is at the end of the potentiometer that is connected to 75. The machineʼs output will increase as the wiper of the potentiometer is moved to the end that is connected to 77. (Note: In TIG mode, moving the lead 76 (wiper) to lead 77 would produce the current that has been set by the EX350ie (CE) front panel Output Control.)

• Remotes of this type offered by Lincoln Electric are the K857, K812 and K870.

AUXILIARY POWER

• 42VAC and 24VAC power is available from the 14pin MS-style connector. These supplies are intended to supply power for auxiliary equipment like wire feeders.

• 42 VAC supply is rated at 5.5 amps and is protected by a 10 amp breaker located by the amphenol.

• 24 VAC supply is rated at 5.5 amps and is protected by a 10 amp breaker located by the amphenol.

LIMITATIONS

• The EX350ie (CE) is not recommended for processes other than those listed.

• The EX350ie (CE) can only be used with the recommended equipment and options.

RECOMMENDED PROCESSES

Properly equipped, the EX350ie (CE) supports GMAW, FCAW, SMAW, GTAW and CAC-A processes for a variety of materials, including mild steel, stainless steel, cored wires, and aluminum

Voltage Control

• The supply should be an isolated supply. (Not referenced to earth ground, any auxiliary power from the EX350ie (CE) or the welding output) should be capable of supplying at least 20mA.

• 0 volts supplied to 76 will set the EX350ie (CE) to minimum output for the mode that has been selected while 10 volts supplied to 76 will set the EX350ie (CE) to the maximum output for the mode. (Note: In TIG mode, 10 volts supplied to lead 76 would produce the current that has been set by the EX350ie (CE) front panel Output Control.)

VISUAL INSPECTION

Clean interior of machine with a low pressure air stream. Make a thorough inspection of all components. Look for signs of overheating, broken leads or other obvious problems. Many problems can be uncovered with a good visual inspection.

ROUTINE MAINTENANCE

1. Every 6 months or so the machine should be cleaned with a low pressure airstream. Keeping the machine clean will result in cooler operation and higher reliability. Be sure to clean these areas:

• All printed circuit boards

• Power switch

• Main transformer

• Input rectifier

• Auxiliary Transformer

• Reconnect Switch Area

• Fan (Blow air through the rear louvers)

2. Examine the sheet metal case for dents or breakage.

Repair the case as required. Keep the case in good condition to insure that high voltage parts are protected and correct spacings are maintained. All external sheet metal screws must be in place to insure case strength and electrical ground continuity.

PERIODIC MAINTENANCE

Overload Protection

The machine is electrically protected from producing high output currents. Should the output current exceed 430A, an electronic protection circuit will reduce the current to approximately 100A. The machine will continue to produce this low current until the protection circuit is reset. Reset occurs when the output load is removed.

CAPACITO TERMINALS

3. Use a DC voltmeter to check that voltage is not present across the terminals on all four capacitors.

EX350ie (CE) (RED-D-ARC)

Thermal Protection

Thermostats protect the machine from excessive operating temperatures. Excessive temperatures may be caused by a lack of cooling air or operating the machine beyond the duty cycle and output rating. If excessive operating temperature should occur, the thermostat will prevent output voltage or current. The meter will remain energized during this time.

Thermostats are self-resetting once the machine cools sufficiently. If the thermostat shutdown was caused by excessive output or duty cycle and the fan is operating normally, the Power Switch may be left on and the reset should occur within a 15 minute period.
