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
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 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
quand on regarde l’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.

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 manufacturer’s
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 manufacturer’s 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 manufacturer’s 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 manufacturer’s recommendations.
vi
Welding Cables
The welding cables should be kept as short as possible and should be positioned close together, running at
or close to floor level.
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.

PARALLEL OPERATION
The INVERTEC® v350-pro (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.

GENERAL DESCRIPTION
PRODUCT DESCRIPTION & DUTY CYCLE
The Invertec®V350-PRO (CE) offers multi mode CV
and CC DC welding and is rated at 350 amps, 34 volts
at a 60% duty cycle with 3 phase input. It is also rated
at 320 amps with single phase input. It is rated at 275
amps, 100% duty cycle.
UPPER CONTROL PANEL
1. AMPS Meter
• Prior to STICK or TIG 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.
2. VOLT METER
• Prior to CV operation (current flow), the meter displays desired preset voltage value (+/- .5V).
• Prior to STICK or TIG 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.
• When in TIG modes, this control sets the maximum
welding current. Full depression of a foot or hand
Amptrol results in the preset level of current.
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
TIG and CV = ON or REMOTE depending if remote
output controls are connected to the machine.

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 autoconfigure 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.
7. WELD MODE SELECT
The Mode Control button selects the following welding
modes desired.
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.
• 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.
Hidden Middle Control Panel – Process
Set Up Panel
The middle control panel is removable to allow for
upgrades (see Field Installed Options/Accessories).
Additionally, this panel is hidden by an access door to
reduce appeared complexity and provide protection to
the controls.

CC-STICK CRISP: The Stick Crisp mode features
continuous control from 5 to 425 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.
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.
TIG SOLENOID OPTION
The Solenoid only operates when th V350 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
preferable for welding FCAW and GMAW with CO
OPERATION
2.
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.
10. The ON-OFF switch is a 3-phase circuit breaker
rated at 100 amps per leg.
11. The METER POLARITY switch is located above
the output connectors. The switch provides a work
connection for wire feeder voltmeters. Place the
switch in the position of the electrode polarity indicated by the decal. The switch does not change
the welding polarity.
12. 6-PIN MS-style connector for remote 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-PRO (CE)’s front panel Output Control.)
• Remotes of this type offered by Lincoln Electric are
the K857, K812 and K870.
Voltage Control
• The supply should be an isolated supply. (Not referenced to earth ground, any auxiliary power from the
®
Invertec
V350-PRO (CE) or the welding output)
The supply should be capable of supplying at least 20mA.
• 0 volts supplied to 76 will set the Invertec®V350PRO (CE) to minimum output for the mode that has
been selected while 10 volts supplied to 76 will set
®
the Invertec
V350-PRO (CE) to the maximum output for the mode. (Note: In TIG mode, 10 volts supplied to lead 76 would produce the current that has

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.
3. Use a DC voltmeter to check that voltage is not
present across the terminals on all four capacitors.
INVERTEC® V350-PRO (CE)
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.
