should conform to ANSI Z87. I standards.

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.

4.b. Use suitable clothing made from durable flame-resistant

material to protect your skin and that of your helpers from

the arc rays.

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.

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.

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:

FUMES AND GASES

can be dangerous.

5.a. Welding may produce fumes and gases

hazardous to health. Avoid breathing these

• Semiautomatic DC Constant Voltage (Wire) Welder.

• DC Manual (Stick) Welder.

• AC Welder with Reduced Voltage Control.

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.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.

5.b. Do not weld in locations near chlorinated hydrocarbon vapors

coming from degreasing, cleaning or spraying operations.

The heat and rays of the arc can react with solvent vapors to

form phosgene, a highly toxic gas, and other irritating prod-

ucts.

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.

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.

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.

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.

3.i. When working above floor level, use a safety belt to protect

yourself from a fall should you get a shock.

SAFETY

WELDING SPARKS can

cause fire or explosion.

CYLINDER may explode

if damaged.

6.a. Remove fire hazards from the welding area.

If this is not possible, cover them to prevent

7.a. Use only compressed gas cylinders

containing the correct shielding gas for the

the welding sparks from starting a fire.

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.

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.

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.

7.c. Cylinders should be located:

•Away from areas where they may be struck or subjected to

physical damage.

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.

•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.

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 though they have

been “cleaned”. For information, purchase “Recommended

Safe Practices for the Preparation for Welding and Cutting of

Containers and Piping That Have Held Hazardous

Substances”, AWS F4.1 from the American Welding Society

(see address above).

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.

6.e. Vent hollow castings or containers before heating, cutting or

welding. They may explode.

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

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.

FOR ELECTRICALLY

powered equipment.

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 cir-

cuits. This can create fire hazards or overheat lifting chains

or cables until they fail.

8.a. Turn off input power using the disconnect

switch at the fuse box before working on

the equipment.

8.b. Install equipment in accordance with the U.S. National

Electrical Code, all local codes and the manufacturer’s

recommendations.

6.h. Also see item 1.c.

8.c. Ground the equipment in accordance with the U.S. National

Electrical Code and the manufacturer’s recommendations.

PRÉCAUTIONS DE SÛRETÉ

6. Eloigner les matériaux inflammables ou les recouvrir afin de

prévenir tout risque d’incendie dû aux étincelles.

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 suiv-

antes:

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.

Sûreté Pour Soudage A L’Arc

1. Protegez-vous contre la secousse électrique:

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 lev-

age, 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.

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.

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.

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.

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.

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.

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.

PRÉCAUTIONS DE SÛRETÉ POUR

LES MACHINES À SOUDER À

TRANSFORMATEUR ET À

REDRESSEUR

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 ray-

onnement 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.

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.

c. Protéger l’autre personnel travaillant à proximité au

soudage à l’aide d’écrans appropriés et non-inflammables.

3. Avant de faires des travaux à l’interieur de poste, la debranch-

er à l’interrupteur à la boite de fusibles.

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, pan-

talons sans revers, et chaussures montantes.

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

place.

5. Toujours porter des lunettes de sécurité dans la zone de

soudage. Utiliser des lunettes avec écrans lateraux dans les

suspended from lift bail.

• Do not lift machine if lift bail is

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

SELECT SUITABLE LOCATION

Do not use Power Wave 455M (CE) in outdoor envi-

ronments. The Power Wave 455M (CE) 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 stack the Power Wave 455M (CE) on top of

any other machine.

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

The bottom machine must always be placed on a

firm, secure, level surface. There is a danger of

machines toppling over if this precaution is not

taken.

Do not mount the Power Wave 455M (CE) over com-

bustible surfaces. Where there is a combustible sur-

face directly under stationary or fixed electrical equip-

ment, that surface shall be covered with a steel plate

at least .060" (1.6mm) thick, which shall extend not

less than 5.90" (150mm) beyond the equipment on all

sides.

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

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.

Place the welder where clean cooling air can freely cir-

culate in through the rear louvers and out through the

case sides and bottom. Dirt, dust, or any foreign mater-

ial 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.

HIGH FREQUENCY PROTECTION

Locate the Power Wave away from radio controlled

machinery.

CAUTION

Machines are equipped with F.A.N. (fan as needed)

circuitry. The fan runs whenever the output is enabled,

whether under loaded or open circuit conditions. The

fan also runs for a period of time (approximately 5 min-

utes) after the output is disabled, to ensure all compo-

nents are properly cooled.

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.

If desired, the F.A.N. feature can be disabled (causing the

fan to run whenever the power source is on). To disable

F.A.N., connect leads 444 and X3A together at the output

of the solid state fan control relay, located on the back of

the Control PC board enclosure. (See Wiring Diagram)

CONNECTIONS

INPUT CONNECTION

Connect a work lead of sufficient size and length (Per

Table 1) between the proper output terminal on the

power source and the work. Be sure the connection to

the work makes tight metal-to-metal electrical contact. 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.

INPUT FUSE AND SUPPLY WIRE

CONSIDERATIONS

CAUTION

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.

When using inverter type power sources like the

Power Waves, use the largest welding (electrode and

work) cables that are practical. At least 67 mm 2/0

copper wire - even if the average output current

would not normally require it. When pulsing, the

pulse current can reach very high levels. Voltage

drops can become excessive, leading to poor weld-

ing characteristics, if undersized welding cables are

used.

For additional Safety information regarding the elec-

trode and work cable set-up, See the standard "SAFE-

TY INFORMATION" located in the front of the

Instruction Manuals.

CABLE INDUCTANCE, AND ITS AFFECT

ON PULSE WELDING

For Pulse Welding processes, cable inductance will

cause the welding performance to degrade. For the

total welding loop length less than 15.24m (50 ft.), tra-

ditional welding cables may be used without any

effects on welding performance. For the total welding

loop length greater than 15.24m (50 ft.), the K1796

Coaxial Welding Cables are recommended. The weld-

ing loop length is defined as the total of electrode

cable length (A) + work cable length (B) + work length

CAUTION

Excessive voltage drops caused by poor work

piece connections often result in unsatisfactory

welding performance.

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

NEGATIVE ELECTRODE POLARITY

When negative electrode polarity is required, such as

in some Innershield applications, switch the output

connections at the power source (electrode cable to

the negative (-) stud, and work cable to the positive (+)

stud).

FIGURE A.3

POWER

WORK

When operating with electrode polarity negative the

"Electrode Sense Polarity" DIP switch must be set to

the "Negative" position on the Wire Drive Feed Head

PC Board. The default setting of the switch is positive

electrode polarity. Consult the Power Feed instruction

manual for further details.

For long work piece lengths, a sliding ground should

be considered to keep the total welding loop length

less than 15.24m (50 ft.). (See Figure A.4.)

WAVE

VOLTAGE SENSING

The best arc performance occurs when the Power

Waves have accurate data about the arc conditions.

Depending upon the process, inductance within the

electrode and work lead cables can influence the

apparent voltage 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 (K940-10, -25 or -50) are available for

this purpose.

spring loaded output cover at the bottom of the case

front.

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.

Most welding applications run with the electrode being

positive (+). For those applications, connect the elec-

trode cable between the wire feeder and the positive

(+) output stud on the power source (located beneath

the spring loaded output cover near the bottom of the

case front). Connect the other end of the electrode

cable to the wire drive feed plate. The electrode cable

lug must be against the feed plate. Be sure the con-

nection to the feed plate makes tight metal-to-metal

electrical contact. The electrode cable should be sized

according to the specifications given in the work cable

connections section. Connect a work lead from the

negative (-) power source output stud to the work

piece. The work piece connection must be firm and

secure, especially if pulse welding is planned.

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

The ELECTRODE sense lead (67) is built into the con-

trol cable, and is automatically enabled for all semi-

automatic processes. The WORK sense lead (21) con-

nects to the Power Wave 455M (CE) at the four pin

connector located underneath the output stud cover.

By default the WORK voltage is monitored at the out-

put stud in the Power Wave 455M (CE). For more

information on the WORK sense lead (21), see "Work

Voltage Sensing” in the following paragraph.

All constant current processes sense the voltage at the

output studs of the Power Wave 455M (CE) by default.

Work Voltage Sensing

The standard Power Wave 455M’s default to the work

stud (work sense lead disabled)

For processes requiring work voltage sensing, con-

nect the (21) work voltage sense lead (K940) from the

Power Wave work sense lead receptacle to the work

piece. Attach the sense lead to the work piece as

close to the weld as practical, but not in the return cur-

rent path. Enable the work voltage sensing in the

Power Wave as follows:

The Power Wave 455M (CE) and semi-automatic

POWER FEED family communicate via a 5 conductor

control cable (K1543). The control cable consists of two

power leads, one twisted pair for digital communication,

and one lead for voltage sensing. The cables are

designed to be connected end to end for ease of exten-

sion. The output receptacle on the Power Wave 455M

(CE) is located beneath the spring loaded output cover at

the bottom of the case front. The input receptacle on the

Power Feed is typically located at the back of the feeder,

or on the bottom of the user interface.

WARNING

• Do not touch electrically live

parts or electrodes with your

skin or wet clothing.

For convenience sake, the electrode and control cables

can be routed behind the left or right strain reliefs (under

the spring loaded output cover), and along the channels

formed into the base of the Power Wave 455M (CE), out

the back of the channels, and then to the wire feeder.

• Insulate yourself from the work

and ground.

• Always wear dry insulating gloves.

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

Due to the flexibility of the platform the configuration may

vary. The following is a general description of the sys-

tem. For specific configuration information, consult the

semi-automatic Power Feed instruction manual.

1. Turn off power to the power source at the discon-

nect switch.

2. Remove the front cover from the power source.

SYSTEM DESCRIPTION

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.

The Power Wave 455M (CE) and Power Feed M family

of products utilize a digital communication system called

ArcLink. Simply put, ArcLink allows large amounts of

information to be passed at very high speeds between

components (nodes) in the system. The system requires

only two wires for communication, and because of its

bus-like structure, the components may be connected to

the network in any order, thus simplifying the system set-

up.

4. Using a pencil or other small object,

slide the switch right to the OFF posi-

tion if the work sense lead is NOT con-

nected. Conversely, slide the switch to

the ON position if the work sense lead

is present.

Each "system" must contain only one power source.

The number of wire feeders is determined by the type

of wire feeder. Refer to the wire feeder instruction

manual for details

5. Replace the cover and screws. The PC board will

“read” the switch at power up, and configure the

work voltage sense lead appropriately.

INSTALLATION

If a system can not be “Auto Mapped” then the status

light on the power source will blink green fast and the

welder output will be disabled. If a system is not

“Auto-mappable”, then consult the instruction manual

for the accessory being used for configuration infor-

mation about DIP switch settings, or consult your local

Lincoln sales representative.

CONFIGURING THE SYSTEM

For codes below 11100, consult the semi-automatic

Power Feed instruction manual for configuration infor-

mation about DIP switch settings.

For codes above 11100 the power source will “Auto

Map” the system eliminating most of the need to set

DIP switches to configure the system.

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

Special care must be taken when more than one

Power Wave is welding simultaneously on a single

part. Arc blow and arc interference may occur or

be magnified.

CAUTION

The use of non-standard cables, especially in

lengths greater than 7.62 (25 feet), can lead to

communication problems (system shutdowns),

poor motor acceleration (poor arc starting) and

low wire driving force (wire feeding problems).

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

The K1543 series of control cables can be connected

end to end for ease of extension. Do not exceed more

than 100 feet (30.5 m) total control cable length.

Each power source requires a work lead from the

work stud to the welding fixture. Do not combine all of

the work leads into one lead. The welding travel direc-

tions should be in the direction moving away from the

work lead as shown below. Connect all of the work

sense leads from each power source to the work

piece at the end of the weld.

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.

Every welding gun requires a separate shielding gas

regulator for proper flow rate and shielding gas cover-

age.

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)

DIP SWITCH SETTINGS AND LOCATIONS

DIP switches on the P.C. Boards allow for custom

configuration of the Power Wave. To access the DIP

switches:

• Turn off power at the disconnect switch.

• Remove the top four screws securing the front

access panel.

• Loosen, but do not completely remove, the bottom

two screws holding the access panel.

• Open the access panel, allowing the weight of the

panel to be carried by the bottom two screws. Make

sure to prevent the weight of the access panel from

hanging on the harness.

• Adjust the DIP switches as necessary.

• Replace the panel and screws, and restore power.

WATER FLOW SENSOR

Water cooled guns can be damaged very quickly if

they are used even momentarily without water flowing.

A water flow sensor is recommended for those water

coolers that do not have an integral flow sensor.

Recommended practice is to install a water flow sen-

sor such as K1536-1 on the water return line of the

torch. When fully integrated into the welding system,

the sensor will prevent welding if no water flow is pre-

sent.

OPERATION

DeviceNet Interface Module

GENERAL DESCRIPTION

This module can be used for DeviceNet capability. It

will be a 5 pin sealed mini connector per ANSI

B93.55M-1981.

The Power Wave 455M (CE) semi-automatic power

source is designed to be a part of a modular, multi-

process welding system. Depending on configuration,

it can support constant current, constant voltage, and

pulse welding modes.

EtherNet/DeviceNet Module

This module includes the DeviceNet and EtherNet

capability. The DeviceNet uses a 5 pin sealed mini

connector per ANSI B93.55M-1981. The EtherNet

uses a RJ5 connector.

The Power Wave 455M (CE) power source is

designed to be used with the semi automatic family of

Power Feed wire feeders, operating as a system.

Each component in the system has special circuitry to

"talk with" the other system components, so each

component (power source, wire feeder, user interface)

knows what the other is doing at all times. These com-

ponents communicate with ArcLink

RECOMMENDED EQUIPMENT

Power Wave 455M (CE) – Semi-Automatic

Operation

Semi Automatic Power Waves can only be used with

ArcLink compatible Power Feed semi-automatic wire

feeders and modules. In addition, the Power Feed

semi-automatic wire feeders may require optional

equipment to access certain weld modes in the Power

Wave. Other models of Lincoln feeders, or any mod-

els of non-Lincoln wire feeders, cannot be used.

The Power Wave 455M (CE) is a high performance,

digitally controlled inverter welding power source

capable of complex, high-speed waveform control.

Properly equipped, it can support the GMAW, GMAW-

P, FCAW, SMAW, GTAW, and CAC processes. It car-

ries an output rating of 400 amps, 36 volts (at 100%

duty cycle).

All welding programs and procedures are selected

through the Power Feed M semi-automatic user inter-

face

RECOMMENDED PROCESSES AND

EQUIPMENT

REQUIRED EQUIPMENT

Any ArcLink compatible semi-automatic wire feeding

equipment. Specifically, the semi-automatic Power

Feed M family.

RECOMMENDED PROCESSES

The Power Wave 455M (CE) can be set up in a num-

ber of configurations, some requiring optional equip-

ment or welding programs. Each machine is factory

preprogrammed with multiple welding procedures, typ-

ically including GMAW, GMAW-P, FCAW, GTAW, and

CAC for a variety of materials, including mild steel,

stainless steel, cored wires, and aluminum.

WARNING

LIMITATIONS

• The Power Waves are not to be used in outdoor

environments.

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

• Only ArcLink compatible Power Feed semi-automat-

ic wire feeders and users interfaces may be used.

Other Lincoln wire feeders or non-Lincoln wire feed-

ers cannot be used.

The Power Wave 455M (CE) is recommended for

semi-automatic welding with ArcLink compatible

equipment like the Power Feed M series of feeders.

The Power Wave 455M (CE) can have a number of

modules installed that allow the machine to be used in

Robotic and hard automation applications.

• Power Wave 455M (CE) Output Limitations

The Power Wave 455M (CE) will support maximum

average output current of 500 Amps @ 60% duty

cycle.

Wire Drive Interface Module

For Robotic platforms the Wire Drive Control Module

is required to drive the Power Feed-10R wire drive.

This module can be factory installed through our

automation division or field installed for robotic appli-

cations.

DUTY CYCLE AND TIME PERIOD

The Power Feed wire feeders are capable of welding

at a 100% duty cycle (continuous welding). The power

source will be the limiting factor in determining system

duty cycle capability. Note that the duty cycle is based

upon a ten minute period. A 60% duty cycle repre-

sents 6 minutes of welding and 4 minutes of idling in a

ten minute period.

The Wire Drive Control Module is also be equipped

with a terminal strip for making simple input signal

connections. It can be used to externally control the

basic wire drive function. It is divided into three

groups: Trigger group, Cold Inch group, and

Shutdown group.

OPERATION

NOMINAL PROCEDURES

WELDING ADJUSTMENTS

The Power Wave 455M (CE) is designed to operate

with 19.1mm (3/4") electrode stick-out for CV and

Pulse processes.

All adjustments are made on the system component

known as the User Interface (Control Box), which con-

tains the switches, knobs, and digital displays neces-

sary to control both the Power Wave 455M (CE) and a

Power Feed wire feeder. Typically, the Control Box is

supplied as part of the wire feeder. It can be mounted

directly on the wire feeder itself, the front of the power

source, or mounted separately, as might be done in a

welding boom installation.

FRINGE PROCEDURES

Excessively short or long electrode stick-outs may

function only on a limited basis, if at all.

MAKING A WELD

Because the Control Box can be configured with many

different options, your system may not have all of the

following adjustments. Regardless of availability, all

controls are described below. For further information,

consult the Power Feed wire feeder instruction manu-

al.

WARNING

The serviceability of a product or structure utiliz-

ing the welding programs is and must be the sole

responsibility of the builder/user. Many variables

beyond the control of The Lincoln Electric

Company affect the results obtained in applying

these programs. These variables include, but are

not limited to, welding procedure, plate chemistry

and temperature, weldment design, fabrication

methods and service requirements. The available

range of a welding program may not be suitable

for all applications, and the build/user is and must

be solely responsible for welding program selec-

tion.

• WFS / AMPS:

In synergic welding modes (synergic CV, pulse

GMAW) WFS (wire feed speed) is the dominant con-

trol parameter, controlling all other variables. The user

adjusts WFS according to factors such as weld size,

penetration requirements, heat input, etc. The Power

Wave then uses the WFS setting to adjust its output

characteristics (output voltage, output current) accord-

ing to pre-programmed settings contained in the

Power Wave 455M (CE). In non-synergic modes, the

WFS control behaves more like a conventional CV

power source where WFS and voltage are indepen-

dent adjustments. Therefore to maintain the arc char-

acteristics, the operator must adjust the voltage to

compensate for any changes made to the WFS.

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

The steps for operating the Power Wave 455M (CE)

will vary depending upon the options installed in the

user interface (control box) of the welding system. The

flexibility of the Power Wave system lets the user cus-

tomize operation for the best performance.

In constant current modes (stick, TIG) this control

adjusts the output current, in amps.

First, consider the desired welding process and the

part to be welded. Choose an electrode material,

diameter, shielding gas and process (GMAW, GMAW-

P, etc.)

• VOLTS / TRIM:

In constant voltage modes (synergic CV, standard

CV) the control adjusts the welding voltage.

Second, find the program in the welding software that

best matches the desired welding process. The stan-

dard software shipped with the Power Waves 455M

(CE) encompasses a wide range of common process-

es and will meet most needs. If a special welding pro-

gram is desired, contact the local Lincoln Electric

sales representative.

In pulse synergic welding modes (pulse GMAW only)

the user can change the Trim setting to adjust the arc

length. It is adjustable from 0.500 to 1.500. A Trim set-

ting of 1.000 is a good starting point for most condi-

tions.

To make a weld, the Power Wave needs to know the

desired welding parameters. The Power Feed (PF)

family of feeders communicate settings to the Power

Wave through control cable connection. Arc length,

wire feed speed, arc control, etc. are all communicat-

ed digitally via the control cable.

B-7

OPERATION

• WELDING MODE

Non Synergic CV:

May be selected by name (CV/MIG, CC/Stick Crisp,

Gouge, etc.) or by a mode number (10, 24, 71, etc.)

depending on the Control Box options. Selecting a

welding mode determines the output characteristics of

the Power Wave power source. For a more complete

description of the welding modes available in the

Power Wave, see the explanation below.

This type of CV mode behaves more like a conven-

tional CV power source. Voltage and WFS are inde-

pendent adjustments. Therefore to maintain the arc

characteristics, the operator must adjust the voltage to

compensate for any changes made to the WFS.

• ARC CONTROL

All CV Modes:

Also known as Inductance or Wave Control. Allows

operator to vary the arc characteristics from "soft" to

"harsh" in all weld modes. It is adjustable from -10.0 to

+10.0, with a nominal setting of 00.0 (The nominal set-

ting of 00.0 may be displayed as OFF on some Power

Feed wire feeder control panels). See the Welding

Mode descriptions, below, for detailed explanations of

how the Arc Control affects each mode.

Arc Control, often referred to as wave control, adjusts

the inductance of the wave shape. The wave control

adjustment is similar to the "pinch" function in that it is

inversely proportional to inductance. Therefore,

increasing wave control greater than 0.0 results in a

harsher, colder arc while decreasing the wave control

to less than 0.0 provides a softer, hotter arc.

(See Figure A.5)

CONSTANT VOLTAGE WELDING

Synergic CV:

For each wire feed speed, a corresponding voltage is

preprogrammed into the machine through special soft-

ware at the factory. The nominal preprogrammed volt-

age is the best average voltage for a given wire feed

speed, but may be adjusted to preference. When the

wire feed speed changes, the Power Wave automati-

cally adjusts the voltage level correspondingly to

maintain similar arc characteristics throughout the

WFS range.

OPERATION

The Power Wave 455M (CE) utilizes "adaptive con-

trol" to compensate for changes in electrical stick-out

while welding. (Electrical stick-out is the distance from

the contact tip to the work piece.) The Power Wave

waveforms are optimized for a 0.75" (19mm) stick-out.

The adaptive behavior supports a range of stickouts

from 0.50" (13mm) to 1.25" (32mm). At very low or

high wire feed speeds, the adaptive range may be

less due to reaching physical limitations of the welding

process.

PULSE WELDING

Pulse welding procedures are set by controlling an

overall "arc length" variable. When pulse welding, the

arc voltage is highly dependent upon the waveform.

The peak current, back ground current, rise time, fall

time and pulse frequency all affect the voltage. The

exact voltage for a given wire feed speed can only be

predicted when all the pulsing waveform parameters

are known. Using a preset voltage becomes impracti-

cal, and instead the arc length is set by adjusting

"trim".

Arc Control, often referred to as wave control, in pulse

programs usually adjusts the focus or shape of the

arc. Wave control values greater than 0.0 increase the

pulse frequency while decreasing the background cur-

rent, resulting in a tight, stiff arc best for high speed

sheet metal welding. Wave control values less than

0.0 decrease the pulse frequency while increasing the

background current, for a soft arc good for out-of-posi-

tion welding.

Trim adjusts the arc length and ranges from 0.50 to

1.50, with a nominal value of 1.00. Trim values greater

than 1.00 increase the arc length, while values less

than 1.00 decrease the arc length.

Most pulse welding programs are synergic. As the

wire feed speed is adjusted, the Power Wave 455M

(CE) will automatically recalculate the waveform para-

meters to maintain similar arc properties.

MAINTENANCE

SAFETY PRECAUTIONS

WARNING

ELECTRIC SHOCK can kill.

• Only Qualified personnel should

perform this maintenance.

• Turn the input power OFF at the

disconnect switch or fuse box

before working on this equipment.

•

Do not touch electrically hot parts.

ROUTINE MAINTENANCE

Routine maintenance consists of periodically blowing

out the machine, using a low pressure airstream, to

remove accumulated dust and dirt from the intake and

outlet louvers, and the cooling channels in the

machine.

PERIODIC MAINTENANCE

Calibration of the Power Wave 455M (CE) is critical to

its operation. Generally speaking the calibration will

not need adjustment. However, neglected or improper-

ly calibrated machines may not yield satisfactory weld

performance. To ensure optimal performance, the cali-

bration of output Voltage and Current should be

checked yearly.

CALIBRATION SPECIFICATION

Output Voltage and Current are calibrated at the facto-

ry. Generally speaking the machine calibration will not

need adjustment. However, if the weld performance

changes, or the yearly calibration check reveals a

problem, contact the Lincoln Electric Company for the

calibration software utility.

The calibration procedure itself requires the use of a

resistive load bank, and certified actual meters for volt-

age and current. The accuracy of the calibration will be

directly affected by the accuracy of the measuring

equipment you use. Detailed instructions are available

with the utility.

USING THE STATUS LED TO

TROUBLESHOOT SYSTEM PROBLEMS

The STATUS LIGHT is a two color light that indicates

system errors. Normal operation is a steady green

light. Error conditions are indicated in the following

chart.

The Power Wave / Power Feed are best diagnosed as

a system. Each component (power source, user inter-

face, and feed head) has a status light, and when a

problem occurs it is important to note the condition of

each. In addition, errors displayed on the user inter-

face in most cases indicate only that a problem exists

in the power source, not what the problem may be.

Therefore, prior to cycling power to the system,

check the power source status light for error

sequences as noted below. This is especially

important if the user interface displays "Err 006"

or "Err 100" .

NOTE: The Power Wave 455M (CE) status light will

flash green, and sometimes red and green, for up to

one minute when the machine is first turned on. This

is a normal situation as the machine goes through a

self test at power up.

Included in this section is information about the power

source Status LED, and some basic troubleshooting

LIGHT CONDITION

MEANING

Status LED is solid green (no blinking).

1. System OK. Power source communicating normally

with wire feeder and its components.

Status LED is blinking green.

2. Occurs during a reset, and indicates the Power

Wave 455M (CE) is mapping (identifying) each com-

ponent in the system. Normal for first 1-10 seconds

after power is turned on, or if the system configura-

tion is changed during operation.

Status LED is blinking red and green.

3. Non-recoverable system fault. If the PS Status light

is flashing any combination of red and green, errors

are present in the Power Wave 455M (CE). Read

the error code before the machine is turned off.

Error Code interpretation through the Status light is

detailed in the Service Manual. Individual code digits

are flashed in red with a long pause between digits. If

more than one code is present, the codes will be

separated by a green light.

To clear the error, turn power source off, and back

on to reset.

Status LED is solid red (no blinking).

Status LED is blinking red.

Non recoverable hardware fault. Generally indicates

nothing is connected to the Power Wave 455M (CE)

wire feeder receptacle. See Trouble Shooting Section.

main transformer or output rectifier.

Low voltage on the main capacitors. May be caused by improper

input configuration.

When accompanied by an overvoltage error on the same side, it

indicates no capacitor voltage present on that side, and is usually

the result of an open or short in the primary side of the machine.

Excess voltage on the main capacitors. May be caused by improp-

er input configuration.

Primary overcurrent error.

Capacitor "A" under voltage

(Left side facing machine)

Capacitor "B" under voltage

(Left side facing machine)

When accompanied by an under voltage error on the same side, it

indicates no capacitor voltage present on that side, and is usually

the result of an open or short in the primary side of the machine.

Capacitor "B" over voltage

(Right side facing machine)

Indicates over temperature. Usually accompanied by Thermal LED.

Check fan operation. Be sure process does not exceed duty cycle

limit of the machine.

Thermal error

Soft start error

Capacitor precharge failed. Usually accompanied by codes 32-35.

The secondary (weld) current limit has been exceeded. When this

occurs the machine output will phase back to 100 amps, typically

resulting in a condition referred to as "noodle welding"

Secondary overcurrent error

NOTE: The secondary limit is 570 amps for the standard stud, and

325 amps.

The maximum voltage difference between the main capacitors has

been exceeded. May be accompanied by errors 32-35.

Capacitor delta error

Single phase error

Indicates machine is running on single phase input power. Usually

caused by the loss of the middle leg (L2).

Error codes that contain three or four digits are defined as fatal

errors. These codes generally indicate internal errors on the PS

Control Board. If cycling the input power on the machine does not

clear the error, try reloading the operating system. If this fails,

replace the control board.
