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.

SAFETY

ii

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.

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.

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

B-4

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

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.

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.
