WARNING

CALIFORNIA PROPOSITION 65 WARNINGS

Diesel engine exhaust and some of its constituents
are known to the State of California to cause can­cer, birth defects, and other reproductive harm.

The Above For Diesel Engines

ARC WELDING CAN BE HAZARDOUS. PROTECT YOURSELF AND OTHERS FROM POSSIBLE SERIOUS INJURY OR DEATH.
KEEP CHILDREN AWAY. PACEMAKER WEARERS SHOULD CONSULT WITH THEIR DOCTOR BEFORE OPERATING.

Read and understand the following safety highlights. For additional safety information, it is strongly recommended that you
purchase a copy of “Safety in Welding & Cutting - ANSI Standard Z49.1” from the American Welding Society, P.O. Box
351040, Miami, Florida 33135 or CSA Standard W117.2-1974. A Free copy of “Arc Welding Safety” booklet E205 is available
from the Lincoln Electric Company, 22801 St. Clair Avenue, Cleveland, Ohio 44117-1199.

BE SURE THAT ALL INSTALLATION, OPERATION, MAINTENANCE AND REPAIR PROCEDURES ARE
PERFORMED ONLY BY QUALIFIED INDIVIDUALS.

The engine exhaust from this product contains
chemicals known to the State of California to cause
cancer, birth defects, or other reproductive harm.

The Above For Gasoline Engines

FOR ENGINE
powered equipment.

1.a. Turn the engine off before troubleshooting and maintenance
work unless the maintenance work requires it to be running.

____________________________________________________

1.b. Operate engines in open, well-ventilated
areas or vent the engine exhaust fumes
outdoors.

____________________________________________________

1.c. Do not add the fuel near an open flame
welding arc or when the engine is running.
Stop the engine and allow it to cool before
refueling to prevent spilled fuel from vaporiz­ing on contact with hot engine parts and
igniting. Do not spill fuel when filling tank. If
fuel is spilled, wipe it up and do not start
engine until fumes have been eliminated.

____________________________________________________

1.d. Keep all equipment safety guards, covers and devices in
position and in good repair.Keep hands, hair, clothing and
tools away from V-belts, gears, fans and all other moving
parts when starting, operating or repairing equipment.

____________________________________________________

1.e. In some cases it may be necessary to remove safety

guards to perform required maintenance. Remove
guards only when necessary and replace them when the
maintenance requiring their removal is complete.
Always use the greatest care when working near moving
parts.

___________________________________________________

1.f. Do not put your hands near the engine fan.
Do not attempt to override the governor or
idler by pushing on the throttle control rods
while the engine is running.

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 engine or welding generator during maintenance
work, disconnect the spark plug wires, distributor cap or
magneto wire as appropriate.

POWER WAVE AC/DC

2.d.4. Connect the work cable to the workpiece as close as
possible to the area being welded.

2.d.5. Do not work next to welding power source.

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
skin or wet clothing. Wear dry, hole-free

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.

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
ventilation and/or exhaust at the arc to keep

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.

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.

5.b.

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.c. 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.

5.d. Read and understand the manufacturer’s instructions for this

equipment and the consumables to be used, including the
material safety data sheet (MSDS) and follow your
employer’s safety practices. MSDS forms are available from
your welding distributor or from the manufacturer.

WELDING SPARKS can
cause fire or explosion.

6.a.

Remove fire hazards from the welding area.

If this is not possible, cover them to prevent

the welding sparks from starting a fire.

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.

6.h. Also see item 1.c.

Remember that welding sparks and hot

though

they have

Preparation

CYLINDER may explode
if damaged.

7.a. Use 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.

7.f. Valve protection caps should always be in place and hand
tight except when the cylinder is in use or connected for
use.

7.g. Read and follow the instructions on compressed gas
cylinders, associated equipment, and CGA publication P-l,
“Precautions for Safe Handling of Compressed Gases in
Cylinders,” available from the Compressed Gas Association
1235 Jefferson Davis Highway, Arlington, VA 22202.

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.

zones où l’on pique le laitier.

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

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 PRECAUTIONS

INSTALLATION

LIFTING

A-2

Read this entire installation section before you
start installation.

WARNING

ELECTRIC SHOCK can kill.

• Only qualified personnel
should perform this installa­tion.

• Turn the input power OFF at

the disconnect switch or fuse
box before working on this

equipment. Turn off the input
power to any other equipment connected to the
welding system at the disconnect switch or fuse
box before working on the equipment.

• Do not touch electrically hot parts.

• Always connect the Power Wave grounding lug

(located inside the reconnect input access door)
to a proper safety (Earth) ground.

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

SELECT SUITABLE LOCATION

Do not use Power Waves in outdoor environments. The
Power Wave power source should not be subjected to
falling water, nor should any parts of it be submerged in
water. Doing so may cause improper operation as well
as pose a safety hazard. The best practice is to keep the
machine in a dry, sheltered area.

Do not mount the PowerWave 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 atleast
.060" (1.6mm) thick, which shall extend not less than

5.90" (150mm) beyond the equipment on all sides.

Lift the machine by the lift bail only. The lift bail is
designed to lift the power source only. Do not attempt
to lift the Power Wave with accessories attached to it.

STACKING

Power Wave AC/DC machine cannot be stacked.

MACHINE GROUNDING

The frame of the welder must be grounded. A ground
terminal marked with the symbol is located inside
the reconnect/input access door for this purpose. See
your local and national electrical codes for proper
grounding methods.

HIGH FREQUENCY PROTECTION

Locate the Power Wave away from radio controlled
machinery.

CAUTION

The normal operation of the Power Wave may
adversely affect the operation of RF controlled
equipment, which may result in bodily injury or
damage to the equipment.

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

Place the welder where clean cooling air can freely
circulate in through the rear louvers and out through
the case sides and bottom. Dirt, dust, or any foreign
material that can be drawn into the welder should be
kept at a minimum. Do not use air filters on the air
intake because the air flow will be restricted. Failure to
observe these precautions can result in excessive
operating temperatures and nuisance shutdowns.

NOTE: Turn main input power to the machine OFF before performing connection procedure. Failure to

do so will result in damage to the machine.

INPUT CONNECTION

WARNING

Only a qualified electrician should connect the
input leads to the Power Wave. Connections
should be made in accordance with all local and
national electrical codes and the connection dia­gram located on the inside of the reconnect/input
access door of the machine. Failure to do so may
result in bodily injury or death.

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

Use a three-phase supply line. A 1.75 inch (45 mm)
diameter access hole for the input supply is located on
the upper left case back next to the input access door.
Connect L1, L2, L3 and ground according to the Input
Supply Connection Diagram decal located on the

inside of the input access door or refer to Figure A.1 .

INPUT FUSE AND SUPPLY WIRE
CONSIDERATIONS

Refer to the Technical Specifications at the beginning
of this Installation section for recommended fuse and
wire sizes. Fuse the input circuit with the recommend-

ed super lag fuse or delay type breakers (also called
“inverse time” or “thermal/magnetic” circuit breakers).
Choose an input and grounding wire size according to
local or national electrical codes. Using fuses or circuit
breakers smaller than recommended may result in
“nuisance” shut-offs from welder inrush currents, even
if the machine is not being used at high currents.

INPUT VOLTAGE CHANGE OVER
(FOR MULTIPLE INPUT VOLTAGE
MACHINES ONLY)

Welders are shipped connected for the highest input
voltage listed on the rating plate. To move this con­nection to a different input voltage, see the diagram
located on the inside of the input access door.

If the Auxiliary (A) lead is placed in the wrong position,
there are two possible results. If the lead is placed in a
position higher than the applied line voltage, the
welder may not come on at all. If the Auxiliary (A) lead
is placed in a position lower than the applied line volt­age, the welder will not come on, and the two circuit
breakers in the reconnect area will open. If this
occurs, turn off the input voltage, properly connect the
(A) lead, reset the breakers, and try again.

POWER WAVE AC/DC

A-4

INSTALLATION

WELDING WITH MULTIPLE UNSYN­CHRONIZED POWER WAVES

CAUTION

A-4

For the best results when pulse welding, set the wire
size and wire feed speed the same for all the Power
Waves. When these parameters are identical, the
pulsing frequency will be the same, helping to stabilize
the arcs.

Special care must be taken when more than one
Power Wave is welding unsynchronized on a sin­gle part. Arc blow and arc interference may occur
or be magnified. Each power source requires a
work lead to the work stud to the welding fixture.
Do not combine all of the work leads into one
lead. Performing welding in the direction away
from the work leads. (In a synchronized multi arc
system the weld should go towards the work
leads to minimize arc blow). Connect all of the
work sense leads from each power source to the
work piece at the end of the weld, such that they
are out of the path of the weld current. For addi­tional information on work voltage sense leads
see sections entitled "Voltage Sensing" and
"Multiple Unsynchronized Arc Sense Lead and
Work Lead Placement Guidelines".

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

FIGURE A.2

TWO POWER WAVES

Every welding gun requires a separate shielding gas
regulator for proper flow rate and shielding gas cover­age. Do not attempt to supply shielding gas for two or
more guns from only one regulator.

If an anti-spatter system is in use then each gun must
have its own anti-spatter system. (See Figure A.2.)

POWER WAVE AC/DC

A-6

INSTALLATION

ELECTRODE AND WORK CABLE
CONNECTIONS

Due to the PowerWave AC/DC’s ability to produce either
a DC positive, DC negative or AC output the electrode
and work connections do not need to be reversed for the
different polarities. Additionally no DIP switch changes
are required to switch between the different polarities. All
of this is controlled internally by the Power Wave AC/DC.
The following directions apply to all polarities:

Connect a work lead of sufficient size (Per Table 1) and
length between the "work" stud (located beneath the
spring loaded output cover on the front of the machine)
and the work. For convenience, the work lead can be
routed behind the left strain relief (under the spring
loaded output cover), along the channels, and out the
back of the machine. Be sure the connection to the work
makes tight metal-to-metal electrical contact. The work
piece connection must be firm and secure. Excessive
voltage drops caused by poor work piece connections
often result in unsatisfactory welding performance, espe­cially if pulse welding is planned. To avoid interference
problems with other equipment and to achieve the best
possible operation, route all cables directly to the work
and wire feeder. Avoid excessive lengths and do not coil
excess cable.

Connect the electrode cable between the wire feeder and
the "electrode" stud on the power source (located behind
the cover plate on the lower right side). For convenience,
the cable can be routed through the oval hole in the rear
of the machine before being connected to the output ter­minals. Connect the other end of the electrode cable to
the wire drive feed plate. Be sure the connection to the
feed plate makes tight metal-to-metal electrical contact.
The electrode cable should be sized according to the
specifications given in (Table A.1).

CABLE INDUCTANCE, AND ITS EFFECTS
ON PULSE WELDING

For Pulse Welding processes, cable inductance will
cause the welding performance to degrade. For the
total welding loop length less than 50 feet, traditional
welding cables may be used without any effects on
welding performance. For the total welding loop length
greater than 50 feet, the K1796 Coaxial Welding
Cables are recommended.
The welding loop length is defined as the total of elec­trode cable length (A) + work cable length (B) + work
length (C) (See Figure A.3).

For long work piece lengths, a sliding ground should
be considered to keep the total welding loop length
less than 50 feet. (See Figure A.4.)

pulse current can reach very high levels. Voltage
drops can become excessive, leading to poor welding
characteristics, if undersized welding cables are used.
NOTE: K1796 coaxial welding cable is recommended
to reduce the cable inductance in long cable lengths.
This is especially important when Pulse welding up to
350 amps.

POWER WAVE AC/DC

CAUTION

INSTALLATION

VOLTAGE SENSING

The best arc performance occurs when the
PowerWave AC/DC has accurate data about the arc
conditions. Depending upon the process, inductance
within the electrode and work lead cables can influ­ence the voltage apparent at the studs of the welder.
Voltage sense leads improve the accuracy of the arc
conditions and can have a dramatic effect on perfor­mance. Sense Lead Kits (K490-series) are available
for this purpose.

CAUTION

If the voltage sensing is enabled but the sense
leads are missing, improperly connected, or if the
electrode polarity switch is improperly configured
extremely high welding outputs may occur.

Work Voltage Sensing
The Power Waves are shipped from the factory
with the work sense lead disabled.

To use work voltage sensing, connect the (21) work
voltage sense lead from the Power Wave to the work.
Attach the sense lead to the work as close to the weld
as practical. Enable the work voltage sensing in the
Power Wave as follows:

WARNING

ELECTRIC SHOCK can kill.

• Do not touch electrically live parts
or electrodes with your skin or wet
clothing.

In extremely sensitive applications requiring volt­age sense leads, it may be necessary to route the
control cable (67 lead) and the work voltage sense
lead (21 lead) away from the electrode and work
welding cables. For more information regarding
the placement of voltage sense leads, see the sec­tion entitled "Welding with Multiple Independent
Power Waves."

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

The ELECTRODE sense lead (67) is built into the
K1795 control cable. The WORK sense lead (21) con­nects to the Power Wave at the four-pin connector
located underneath the output stud cover.
Enable the voltage sense leads as follows:

• Insulate yourself from the work and
ground.

• Always wear dry insulating gloves.

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

1. Turn off power to the power source at the discon­nect switch.

2. Remove the front cover from the power source.

3. The control board is on the left side of
the power source. Locate the 8-position
DIP switch and look for switch 8 of the
DIP switch.

4. Using a pencil or other small object,
slide the switch to the OFF position if
the work sense lead is NOT connected.
Conversely, slide the switch to the ON
position if the work sense lead is pre­sent.

5. Replace the cover and screws. The PC board will
(read) the switch at power up, and configure the
work voltage sense lead appropriately.

Electrode Voltage Sensing

Enabling or disabling electrode voltage sensing is
automatically configured through software. The 67
electrode sense lead is internal to the cable to the
wire feeder and always connected when a wire feeder
is present.

CONTROL CABLE CONNECTIONS
BETWEEN POWER SOURCE AND
WIREFEEDER

Connect the control cable between the power source
and wire feeder. The wire feeder connection on the
PowerWave AC/DC is located under the spring loaded
output cover, on the case front. The control cable is
keyed and polarized to prevent improper connect.

For convenience, the control cables can be routed
behind the left or right strain relief (under the spring
loaded output cover), along the channels of the Power
Wave, out the back of the channels, and then to the
wire feeder.

CAUTION

Excessive voltage drops at the work piece con­nection often result in unsatisfactory pulse weld­ing performance.

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

CONTROL CABLE CONNECTIONS
BETWEEN POWER SOURCES RUN
IN PARALLEL

The connectors located on the rear of the machine are
used for synchronizing the operation of multiple
machines. To run machines in parallel connect the
control cable (K1795 series) between power sources
that are to run in parallel. The bottom (male) connec­tor on the master connects to the top (female) connec­tor on the slave. If needed the bottom connector on
the slave machine is then used to connect to another
slave machine. This connection scheme is duplicated
for any additional slaves.

CONTROL CABLE CONNECTIONS
BETWEEN A POWER SOURCE
AND PHASE GENERATOR

If multiple arcs need to be synchronized an external
phase generator is required. The phase generator is
connected to all of the master machines. A control
cable (K1795 series) should be connected between
the phase generator and the top (female) connector
on the rear of the master machine.

CONTROL CABLE SPECIFICATIONS

It is recommended that genuine Lincoln control cables
be used at all times. Lincoln cables are specifically
designed for the communication and power needs of
the Power Wave / Power Feed system.

CAUTION

The use of non-standard cables, especially in
lengths greater than 25 feet, can lead to communi­cation problems (system shutdowns), poor motor
acceleration (poor arc starting) and low wire dri­ving force (wire feeding problems). Use the short­est length of control cable possible. Do not coil
excess cable as this can cause communication
problems (system shutdowns).

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

Lincoln control cables are copper 22 conductor cable
in a SO-type rubber jacket.

The K1795 series of control cables can be added in
series as needed. Do not exceed more than 100 feet
(30.5 m) total control cable length.

ETHERNET CONNECTIONS

The PowerWave is equipped with an Ethernet con­nector, which is located under the spring loaded out­put cover. All Ethernet cables external to either a con­duit or an enclosure should be solid, shielded with a
drain, cat 5 cable. The drain should be grounded. Do
not use cat 5+, cat 5E, cat 6 or stranded cable. If con­nection failure during welding persists reroute cables
away from any other cables that carry current or other
devices that would create a magnetic field. See Figure
A.4a.
