1.h. To avoid scalding, do not remove the radiator pressure cap when the engine is hot.
ELECTRIC AND MAGNETIC FIELDS may be dangerous
2.a. Electric current flowing through any conductor causes localized Electric and Magnetic Fields (EMF). Welding current creates EMF fields around welding cables and welding machines
2.b. EMF fields may interfere with some pacemakers, and welders having a pacemaker should consult their physician before welding.
2.c. Exposure to EMF fields in welding may have other health effects which are now not known.
2.d. All welders should use the following procedures in order to minimize exposure to EMF fields from the welding circuit:
2.d.1.
Route the electrode and work cables together - Secure them with tape when possible.
2.d.2. Never coil the electrode lead around your body.
2.d.3. Do not place your body between the electrode and
work cables. If the electrode cable is on your right side, the work cable should also be on your right side.
___________________________________________________
1.g. To prevent accidentally starting gasoline engines while turning the work, disconnect the spark plug wires, distributor cap or magneto wire as appropriate.

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.
3.j. Also see Items 6.c. and 8.

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.
5.d. Shielding gases used for arc welding can displace air and
cause injury or death. Always use enough ventilation, especially in confined areas, to insure breathing air is safe.

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.

7.a. Us e only compressed gas cylinders containing the correct shielding gas for the process used and properly operating regulators designed for the gas and
pressure used. All hoses, fittings, etc. should be suitable for the application and maintained in good condition.
7.b. Always keep cylinders in an upright position securely chained to an undercarriage or fixed support.
7.c. Cylinders should be located:
• Away from areas where they may be struck or subjected to
physical damage.
• A safe distance from arc welding or cutting operations and
any other source of heat, sparks, or flame.
7.d. Never allow the electrode, electrode holder or any other electrically “hot” parts to touch a cylinder.
7.e. Keep your head and face away from the cylinder valve outlet when opening the cylinder valve.

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 L’Arc
1. Protegez-vous contre la secousse électrique:
a. Les circuits à l’électrode 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 s’isoler 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 l’eau 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 totaldelatensionàvidedesdeuxmachines.
f. Si on utilise la machine à souder comme une source de
courant pour soudage semi-automatique, ces precautions pour le porte-électrode s’applicuent aussi au pistolet de soudage.
6. Eloigner les matériaux inflammables ou les recouvrir afin de prévenir tout risque d’incendie 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 d’incendie.
8. S’assurer que la masse est connectée le plus prés possible de la zone de travail qu’il est pratique de le faire. Si on place la masse sur la charpente de la construction ou d’autres 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 d’incendie ou d’echauffement des chaines et des câbles jusqu’à ce qu’ils 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 d’opérations de dégraissage, nettoyage ou pistolage. La chaleur ou les rayons de l’arc 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 n’importe quelle partie du corps.
3. Un coup d’arc peut être plus sévère qu’un coup de soliel, donc:
a. Utiliser un bon masque avec un verre filtrant approprié
ainsi qu’un verre blanc afin de se protéger les yeux du ray­onnement de l’arc et des projections quand on soude ou quandonregardel’arc.
b. Porter des vêtements convenables afin de protéger la
peau de soudeur et des aides contre le rayonnement de l‘arc.
c. Protéger l’autre personnel travaillant à proximité au
soudage à l’aide d’écrans appropriés et non-inflammables.
4. Des gouttes de laitier en fusion sont émises de l’arc de soudage. Se protéger avec des vêtements de protection libres de l’huile, tels que les gants en cuir, chemise épaisse, pan­talons sans revers, et chaussures montantes.
5. Toujours porter des lunettes de sécurité dans la zone de soudage. Utiliser des lunettes avec écrans lateraux dans les zones où l’on pique le laitier.
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 l’électricité 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, I’installation et l’entretien du poste seront effectués par un électricien qualifié.
3. Avant de faires des travaux à l’interieur de poste, la debranch­er à l’interrupteur à la boite de fusibles.
4. Garder tous les couvercles et dispositifs de sûreté à leur place.

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 U.S.National Electrical Code.
----------------------------------------------------------------------
SELECT SUITABLE LOCATION
The Invertec V350-PIPE 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
V350-PIPE 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
Invertec V350-PIPE. 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 460VAC. If 460VAC is the desired input, then the machine may be connected to the power system without any setup required inside the machine.
• Initial 200VAC - 415VAC and 575VAC operation will require an Input voltage panel setup.
be stacked.
V350-PIPE
A-2
• 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 380-575.
• Move the "A" lead to the appropriate terminal.
POWER CORD CONNECTION
A 10 ft. power cord is provided and wired into the machine. Follow the power cord connection instruc­tions.
CAUTION
Incorrect connection may result in equipment damage.

PARALLEL OPERATION
The V350-PIPE 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.

GENERAL DESCRIPTION
The Invertec V350-PIPE offers DC Stick and Innershield welding.
DUTY CYCLE
The V350-PIPE is rated at 350 amps, 60% duty cycle (based on a 10 minute cycle). It is also rated at 300 amps, 100% duty cycle.
OPERATIONAL FEATURES and CONTROLS:
• Prior to CV operation (current flow), the meter dis­plays desired preset voltage value (+/- .5V).
• Prior to STICK operation, the meter displays the Open Circuit Voltage of the Power Source or four dashes if the output has not been turned on.
• During welding, this meter displays actual average volts.
• After welding, the meter holds the actual voltage value for 5 seconds. The displays blink indicating that the machine is in the "Hold" period.
• Output adjustment while in the "hold" period results in the "prior to operation" characteristics stated above.
3. OUTPUT CONTROL
• Output control is conducted via a single turn poten­tiometer.
• Adjustment is indicated by the meters as stated above.
4. WELD TERMINALS-REMOTE / ON
• Two status lights indicate the location of trigger con­trol as determined by the "WELD TERMINALS" push button.
• If trigger control is local "weld terminals on", the ON display will be lit.
• If trigger control is remote "weld terminals remotely controlled", the REMOTE display will be lit.
• The unit will power up in "pre-determined preferred" trigger modes.
STICK = ON CV = REMOTE
For all versions, these trigger modes can be over-ridden (switched) with the WELD TERMINALS push button. When changed, the unit will power up in the configuration it was in when it was last powered down.
UPPER CONTROL PANEL
1. AMPS Meter
• Prior to STICK operation (current flow), the meter displays preset current value (either 2 amps or +/­3% (e.g. 3 amps on 100), whichever is greater).
• Prior to CV operation, the meter displays four dash­es indicating non-presettable AMPS.
• During welding, this meter displays actual average amps.
• After welding, the meter holds the actual current value for 5 seconds. Output adjustment while in the "hold" period results in the "prior to operation" char­acteristics stated above. The displays blink indicat­ing that the machine is in the "Hold" period.
V350-PIPE
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.

7. WELD MODE SELECT - FACTORY AND CONSTRUCTION (See Figure B.1)
The Mode Control button selects from the following welding modes.
B-2
• 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 60 to 250 amps. This mode was intended primarily for pipe welding applications.
• The Hot Start control regulates the starting current at arc initiation. Hot Start can adjust starting current up or down by 25% of the preset value. The recom­mended setting for Hot Start is 5 where the initial current is equal to the preset current.
• 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 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 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".
• 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.

CV-INNERSHIELD: The CV-INNERSHIELD mode features continuous control from 15 to 29 volts. This mode was designed for 5/64 NR 207 on Pipe Welding Applications.
• 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.
The pinch control was optimized for NR207 at an Arc Control setting of 0.0.

Types of Remote OUTPUT CONTROL
• The Invertec V350-PIPE’S 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 machine’s 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 Invertec V350-PIPE’S front panel Output Control.)
• Remotes of this type offered by Lincoln Electric are the K857, K812 and K870.
REMOTE CONTROL of the OUTPUT CONTROL and WELD TERMINALS
The Invertec V350-PIPE has auto sensing of remote output controls. If after connecting or removing a remote, the Invertec V350-PIPE did not configure 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 connectors.)
CV modes
• The remote will default to the 14-pin MS-style con­nector 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.
CC-Stick modes
• The remote will default to only the 6-pin MS-style connector if a remote is connected to it.
• The WELD TERMINAL control will default to ON with or without a remote connected.
Voltage Control
• The supply should be an isolated supply. (Not refer­enced to earth ground, any auxiliary power from the Invertec V350-PIPE or the welding output) The sup­ply should be capable of supplying at least 20mA.
• 0 volts supplied to 76 will set the Invertec V350­PIPE to minimum output for the mode that has been selected while 10 volts supplied to 76 will set the Invertec V350-PIPE 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 Invertec V350-PIPE’s front panel Output Control.)
V350-PIPE

Types of Remote WELD TERMINAL Control
• The Invertec V350-PIPE’S Weld Terminals can be controlled from each of the MS-style 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 Invertec V350-PIPE.
• 14-Pin MS-style connector, the Weld Terminals are controlled from pin C (lead 2) and pin D (lead 4). Pin C is positive.
• 6-Pin MS-style connector, the Weld Terminals are controlled from pin D (lead 2) and pin E (lead 4). In the 6-pin MS-style connector pin D is positive.
OPERATION
AUXILIARY POWER
• 42 VAC and 24 VAC 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 6 amp breaker.
• 24 VAC supply is rated at 5.5 amps and is protected by a 6 amp breaker.

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