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. 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.
5.e. Read and understand the manufacturerʼs instructions for this
equipment and the consumables to be used, including the
material safety data sheet (MSDS) and follow your
employerʼs safety practices. MSDS forms are available from
your welding distributor or from the manufacturer.

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 LʼArc
1. Protegez-vous contre la secousse électrique:
a. Les circuits à lʼélectrode 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 sʼisoler 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 lʼeau 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 sʼapplicuent 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 nʼimporte quelle partie
du corps.
3. Un coup dʼarc peut être plus sévère quʼun coup de soliel,
donc:
a. Utiliser un bon masque avec un verre filtrant approprié
ainsi quʼun verre blanc afin de se protéger les yeux du rayonnement de lʼarc et des projections quand on soude ou
quand on regarde lʼarc.
b. Porter des vêtements convenables afin de protéger la
peau de soudeur et des aides contre le rayonnement de
lʻarc.
c. Protéger lʼautre personnel travaillant à proximité au
soudage à lʼaide dʼécrans appropriés et non-inflammables.
4. Des gouttes de laitier en fusion sont émises de lʼarc de
soudage. Se protéger avec des vêtements de protection libres
de lʼhuile, 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 lʼon pique le laitier.
6. Eloigner les matériaux inflammables ou les recouvrir afin de
prévenir tout risque dʼincendie 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 dʼincendie.
8. Sʼassurer que la masse est connectée le plus prés possible
de la zone de travail quʼil est pratique de le faire. Si on place
la masse sur la charpente de la construction ou dʼautres
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 dʼincendie ou dʼechauffement des chaines et des
câbles jusquʼà ce quʼils 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
dʼopérations de dégraissage, nettoyage ou pistolage. La
chaleur ou les rayons de lʼarc 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,

SAFETY
Electromagnetic Compatibility (EMC)
Conformance
Products displaying the CE mark are in conformity with European Community Council Directive of 3 May
1989 on the approximation of the laws of the Member States relating to electromagnetic compatibility
(89/336/EEC). It was manufactured in conformity with a national standard that implements a harmonized
standard: EN 60974-10 Electromagnetic Compatibility (EMC) Product Standard for Arc Welding Equipment.
It is for use with other Lincoln Electric equipment. It is designed for industrial and professional use.
Introduction
All electrical equipment generates small amounts of electromagnetic emission. Electrical emission may be
transmitted through power lines or radiated through space, similar to a radio transmitter. When emissions
are received by other equipment, electrical interference may result. Electrical emissions may affect many
kinds of electrical equipment; other nearby welding equipment, radio and TV reception, numerical controlled
machines, telephone systems, computers, etc. Be aware that interference may result and extra precautions
may be required when a welding power source is used in a domestic establishment.
Installation and Use
The user is responsible for installing and using the welding equipment according to the manufacturerʼs
instructions. If electromagnetic disturbances are detected then it shall be the responsibility of the user of the
welding equipment to resolve the situation with the technical assistance of the manufacturer. In some cases
this remedial action may be as simple as earthing (grounding) the welding circuit, see Note. In other cases it
could involve construction an electromagnetic screen enclosing the power source and the work complete
with associated input filters. In all cases electromagnetic disturbances must be reduced to the point where
they are no longer troublesome.
v
Note: The welding circuit may or may not be earthed for safety reasons according to national codes.
Changing the earthing arrangements should only be authorized by a person who is competent to access whether the changes will increase the risk of injury, e.g., by allowing parallel
welding current return paths which may damage the earth circuits of other equipment.
Assessment of Area
Before installing welding equipment the user shall make an assessment of potential electromagnetic problems in the surrounding area. The following shall be taken into account:
a) other supply cables, control cables, signaling and telephone cables; above, below and adjacent to the
welding equipment;
b) radio and television transmitters and receivers;
c) computer and other control equipment;
d) safety critical equipment, e.g., guarding of industrial equipment;
e) the health of the people around, e.g., the use of pacemakers and hearing aids;
f) equipment used for calibration or measurement
g) the immunity of other equipment in the environment. The user shall ensure that other equipment being
used in the environment is compatible. This may require additional protection measures;
h) the time of day that welding or other activities are to be carried out.

SAFETY
Electromagnetic Compatibility (EMC)
The size of the surrounding area to be considered will depend on the structure of the building and other
activities that are taking place. The surrounding area may extend beyond the boundaries of the premises.
Methods of Reducing Emissions
Mains Supply
Welding equipment should be connected to the mains supply according to the manufacturerʼs recommendations. If interference occurs, it may be necessary to take additional precautions such as filtering of the mains
supply. Consideration should be given to shielding the supply cable of permanently installed welding equipment, in metallic conduit or equivalent. Shielding should be electrically continuous throughout its length. The
shielding should be connected to the welding power source so that good electrical contact is maintained
between the conduit and the welding power source enclosure.
Maintenance of the Welding Equipment
The welding equipment should be routinely maintained according to the manufacturerʼs recommendations.
All access and service doors and covers should be closed and properly fastened when the welding equipment is in operation. The welding equipment should not be modified in any way except for those changes
and adjustments covered in the manufacturers instructions. In particular, the spark gaps of arc striking and
stabilizing devices should be adjusted and maintained according to the manufacturerʼs recommendations.
vi
Welding Cables
The welding cables should be kept as short as possible and should be positioned close together, running at
or close to floor level.
Equipotential Bonding
Bonding of all metallic components in the welding installation and adjacent to it should be considered.
However, metallic components bonded to the work piece will increase the risk that the operator could
receive a shock by touching these metallic components and the electrode at the same time. The operator
should be insulated from all such bonded metallic components.
Earthing of the Workpiece
Where the workpiece is not bonded to earth for electrical safety, not connected to earth because of its size
and position, e.g., ships hull or building steelwork, a connection bonding the workpiece to earth may reduce
emissions in some, but not all instances. Care should be taken to prevent the earthing of the workpiece
increasing the risk of injury to users, or damage to other electrical equipment. Where necessary, the connection of the workpiece to earth should be made by a direct connection to the workpiece, but in some countries
where direct connection is not permitted, the bonding should be achieved by suitable capacitance, selected
according to national regulations.
Screening and Shielding
Selective screening and shielding of other cables and equipment in the surrounding area may alleviate problems of interference. Screening of the entire welding installation may be considered for special applications.

INPUT AND GROUNDING CONNECTIONS
A-4
Choose input and grounding wire size according to local or
national electrical codes. Using input wire sizes, 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.
Power Supply Connection for the Fanuc R30iA
Controller
The POWER WAVE® i400 is equipped with a dedicated
robot power terminal block (4TB) specifically designed to
feed input power directly to the Fanuc R30iA controller
through the power source rotary ON/OFF switch. The
K2677-1 Integration kit provides the proper cable and installations instructions to make this connection.
MACHINE GROUNDING
The frame of the welder must be
grounded. A ground terminal marked with the symbol
shown is located inside the reconnect/input access door for
this purpose. See your local and national electrical codes
for proper grounding methods.
INPUT CONNECTIONS
WARNING
ELECTRIC SHOCK can kill.
• 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 case
back. Connect L1, L2, L3 and ground according to the input
supply and ground connection decals located near the input
power terminal block (1TB) and ground block inside of the
rear input reconnect box.
WARNING
The POWER WAVE® i400 on/off switch is not intended
as a service disconnect for this equipment. 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 access door of the machine. Failure to do so
may result in bodily injury or death.
Do not attempt to back feed input power though the
robot power terminal block (4TB) into the POWER
WAVE® i400. This is not its intended purpose and may
result in machine damage, bodily injury or death.
Input Fuse and Supply Wire Considerations
Refer to Specification in Installation Section for recommended fuse, wire sizes and type of the copper wires. Fuse the
input circuit with the recommended super lag fuse or delay
type breakers (also called "inverse time" or "thermal/magnetic" circuit breakers).

ELECTRODE AND WORK CONNECTIONS
Connect the electrode and work cables between the
appropriate output studs of the POWER WAVE® i400
and the robot weld cell per the connection diagrams
included in this document. Size and route the cables
per the following.
• Most welding applications run with the electrode
being positive (+). For those applications, connect
the electrode cable between the wire drive feed plate
and the positive (+) output stud on the power source.
Connect a work lead from the negative (-) power
source output stud to the work piece.
• When negative electrode polarity is required, such
as in some Innershield applications, reverse the output connections at the power source (electrode cable
to the negative (-) stud, and work cable to the positive (+) stud).
CAUTION
Negative electrode polarity operation WITHOUT
use of a remote work sense lead (21) requires the
Negative Electrode Polarity attribute to be set. See
the Remote Sense Lead Specification section of
this document for further details.
For additional Safety information regarding the electrode and work cable set-up, See the standard “SAFETY INFORMATION” located in the front of this
Instruction Manual.
TABLE A.1
OUTPUT CABLE GUIDELINES
GENERAL GUIDELINES
• Select the appropriate size cables per the
“Output Cable Guidelines” in Table A.1.
Excessive voltage drops caused by undersized
welding cables and poor connections often result in
unsatisfactory welding performance. Always use the
largest welding cables (electrode and work) that are
practical, and be sure all connections are clean and
tight.
Note: Excessive heat in the weld circuit indicates
undersized cables and/or bad connections.
• Route all cables directly to the work and wire
feeder, avoid excessive lengths and do not coil
excess cable. Route the electrode and work cables
in close proximity to one another to minimize the
loop area and therefore the inductance of the weld
circuit.
• Always weld in a direction away from the work
(ground) connection.
In Table A.1 are copper cable sizes recommended for
different currents and duty cycles. Lengths stipulated
are the distance from the welder to work and back to
the welder again. Cable sizes are increased for
greater lengths primarily for the purpose of minimizing
cable drop.
Excessive cable inductance will cause the welding
performance to degrade. There are several factors
that contribute to the overall inductance of the cabling
system including cable size, and loop area. The loop
area is defined by the separation distance between
the electrode and work cables, and the overall welding
loop length. The welding loop length is defined as the
total of length of the electrode cable (A) + work cable
(B) + work path (C) (see Figure A.2). To minimize
inductance always use the appropriate size cables,
and whenever possible, run the electrode and work
cables in close proximity to one another to minimize
the loop area. Since the most significant factor in
cable inductance is the welding loop length, avoid
excessive lengths and do not coil excess cable. For
long work piece lengths, a sliding ground should be
considered to keep the total welding loop length as
short as possible.

WORK
REMOTE SENSE LEAD CONNECTIONS
Voltage Sensing Overview
The best arc performance occurs when the POWER
WAVE® i400 has accurate data about the arc conditions. Depending upon the process, inductance within
the electrode and work cables can influence the voltage apparent at the studs of the welder, and have a
dramatic effect on performance. Remote voltage
sense leads are used to improve the accuracy of the
arc voltage information supplied to the control pc
board. Sense Lead Kits (K940-xx) are available for
this purpose.
General Guidelines for Voltage Sense Leads
Sense leads should be attached as close to the weld
as practical, and out of the weld current path when
possible. In extremely sensitive applications it may be
necessary to route cables that contain the sense
leads away from the electrode and work welding
cables.
Voltage sense leads requirements are based on the
weld process as follows:

control cable (K1785).
2
The work voltage sense lead (21) is manually enabled, but overridden by constant current weld processes defined for stud sensing.
3
Negative polarity semi-automatic process operation WITHOUT
use of a remote work sense lead (21) requires the Negative
Electrode Polarity attribute to be set. This establishes which output stud the electrode voltage sense lead (67) will be referenced
to.
Voltage sense at studsVoltage sense at studs

Electrode Voltage Sensing
The remote ELECTRODE sense lead (67) is built into
the standard wire feeder control cable (K1785) and is
always connected to the wire drive feed plate when a
wire feeder is present. Enabling or disabling electrode
voltage sensing is application specific, and automatically configured by the active weld mode.
The remote ELECTRODE sense lead (67) is also
available in the remote Voltage Sense Connector for
applications that do not use the standard wire feeder
control cable (K1785). This can be easily accessed
with the optional K940 Sense Lead kit.
CAUTION
If the remote voltage sensing is enabled but the
sense leads are missing, improperly connected, or
if the electrode polarity attribute is improperly
configured extremely high welding outputs may
occur.
The POWER WAVE® i400 is configured at the factory
to sense work voltage at the negative output stud
(positive output polarity with remote Work Voltage
Sensing disabled).
CAUTION
Negative electrode polarity operation WITHOUT
use of a remote work sense lead (21) requires the
Negative Electrode Polarity attribute to be set via
the Fanuc Teach Pendant or with the Weld
Manager Utility (included on the Power Wave
Utilities and Service Navigator CDʼs or available at
www.powerwavesoftware.com).
While most applications perform adequately by sensing the work voltage directly at the output stud, the
use of a remote work voltage sense lead is recommended for optimal performance. The remote WORK
sense lead (21) can be accessed through the four-pin
voltage sense connector located on the control panel
by using the K940 Sense Lead Kit. It must be
attached to the work as close to the weld as practical,
but out of the weld current path. For more information
regarding the placement of remote work voltage sense
leads, see the section entitled "Voltage Sensing
Considerations for Multiple Arc Systems."
If a remote work voltage sense lead is used, it
must be enabled through the Fanuc Teach
Pendant or with the Weld Manager Utility (included on the Power Wave Utilities and Service
Navigator CDʼs or available at
www.powerwavesoftware.com).
Voltage Sensing Considerations for Multiple Arc
Systems
Special care must be taken when more than one arc
is welding simultaneously on a single part. Multiple
arc applications do not necessarily dictate the use of
remote work voltage sense leads, but they are strongly recommended.
If Sense Leads ARE NOT Used:
• Avoid common current paths. Current from adjacent arcs can induce voltage into each others current paths that can be misinterpreted by the power
sources, and result in arc interference.
If Sense Leads ARE Used:
• Position the sense leads out of the path of the
weld current. Especially any current paths com-
mon to adjacent arcs. Current from adjacent arcs
can induce voltage into each others current paths
that can be misinterpreted by the power sources,
and result in arc interference.
FIGURE A.3
DIRECTION
OF TRAVEL
POWER WAVE® i400
• For longitudinal applications, connect all work
leads at one end of the weldment, and all of the
work voltage sense leads at the opposite end of the
weldment. Perform welding in the direction away
from the work leads and toward the sense leads.

CONTROL CABLE CONNECTIONS
General Guidelines
Genuine Lincoln control cables should be used at all
times (except where noted otherwise). Lincoln cables
are specifically designed for the communication and
power needs of the POWER WAVE® / Power Feed systems. Most are designed to be connected end to end for
ease of extension. Generally, it is recommended that the
total length not exceed 100 ft. (30.5 m). The use of nonstandard cables, especially in lengths greater than 25 ft.
(7.6 m), can lead to communication problems (system
shutdowns), poor motor acceleration (poor arc starting),
and low wire driving force (wire feeding problems).
Always use the shortest length of control cable possible,
and DO NOT coil excess cable.
Regarding cable placement, best results will be
CAUTION
obtained when control cables are routed separate
from the weld cables. This minimizes the possibility
of interference between the high currents flowing
through the weld cables, and the low level signals in
the control cables. These recommendations apply to
all communication cables including ArcLink® and
Ethernet connections.
Connection Between Power Source and Wire Feeder
(K1785 or K2709 Control Cable)
The 14 pin wire feeder control cable connects the power
source to the wire drive. It contains all of the necessary
signals to drive the motor and monitor the arc, including
the motor power, tachometer, and arc voltage feedback
signals. The wire feeder connection on the POWER
WAVE® i400 is located on the recessed control panel
above the output studs. Fanuc robot arms are equipped
with internal cabling and provide a standard 14 pin MSstyle connection at the base of the robot, and near the
wire feeder mount at the top of the arm. The K2709
series external dress cable is recommended for severe
duty applications such as hard automation or for robot
arms not equipped with an internal control cable. Best
results will be obtained when control cables are routed
separate from the weld cables, especially in long distance applications. Maximum cable length should not
exceed 100ft(30.5m).
A-16
Connection Between Power Source and ArcLink®XT
Compatible Controllers or Ethernet Networks. Newer
model controllers, such as the Fanuc R30iA, communicate
via ArcLink®XT over an industrial Ethernet connection. To
facilitate this, the Power Wave i400 is equipped with an IP67
rated ODVA compliant RJ-45 Ethernet connector, which is
located on the recessed control panel above the output
studs. A special access chute is provided above the
Ethernet connection on the Power Wave i400 to accommodate seamless integration with the Fanuc R30iA controller.
The K2677-1 Integration Kit includes a specially designed
industrial rated Ethernet cable for this purpose.
It is highly recommended that all external Ethernet equipment (cables, switches, etc.), as defined by the connection
diagrams, be obtained through the Lincoln Electric
Automation Division. It is critical that all Ethernet cables
external to either a conduit or an enclosure are solid conductor, shielded cat 5e cable, with a drain. The drain should
be grounded at the source of transmission, such as a network switch or the Fanuc R30iA ground strip. Ethernet
cables will achieve optimal performance levels at distances
up to 25 feet. Special attention to layout may be required to
support distances greater than 25 feet, including specialized
network equipment. For best results, always route Ethernet
cables away from weld cables, wire drive control cables, or
any other current carrying device that can create a fluctuating magnetic field. For additional guidelines refer to industry
standard documents for industrial Ethernet networks. Failure
to follow these recommendations can result in an Ethernet
connection failure during welding.
The ethernet port of the Power Wave i400 is factory configured with a dynamic IP address. This is required for seamless operation with the Fanuc R30iA controller.
Connection Between Power Source and ArcLink®
Compatible Controllers (K1543 or K2683 ArcLink
Control Cable)
Earlier model Fanuc controllers communicate via traditional
ArcLink® over a standard 2 wire CAN based network. In
these systems, the 5 pin ArcLink control cable connects the
power source to the controller.
The control cable consists of two power leads, one twisted
pair for digital communication, and one lead for voltage
sensing. The sense leads and power leads are typically
unused in this application. The 5 pin ArcLink connection on
the POWER WAVE® i400 is located on the recessed control
panel above the output studs. The control cable is keyed
and polarized to prevent improper connection. Best results
will be obtained when control cables are routed separate
from the weld cables, especially in long distance applications. The recommended combined length of the ArcLink
control cable network should not exceed 200ft(61.0m).
POWER WAVE® i400

Connections Between Power Source and Optional
DeviceNet PLC Controller. Hard Automation applica-
tions and some earlier model controllers may require
DeviceNet connectivity to control the power source.
DeviceNet can also be used to monitor welding data,
and system status information. The optional K2780-1
DeviceNet Kit is available for this purpose. It includes
a 5 pin DeviceNet sealed mini style receptacle that
mounts on the recessed control panel of the Power
Wave i400, above the output studs. The DeviceNet
cable is keyed and polarized to prevent improper connection. For best results, route DeviceNet cables
away from weld cables, wire drive control cables, or
any other current carrying device that can create a
fluctuating magnetic field. DeviceNet cables must be
sourced locally by the customer. For additional guidelines refer to the “DeviceNet Cable Planning and
Installation Manual” (Allen Bradley publication DN-
6.7.2).
The DeviceNet MAC ID and baud rate of the POWER
WAVE® i400 can be configured with the Diagnostics
Utility (included on the POWER WAVE® Utilities and
Service Navigator CDʼs or available at

OTHER SET-UP ISSUES
Selecting a Wire Drive and Setting the Wire Drive
Gear Ratio. The POWER WAVE® i400 can accom-
modate a number of standard wire drives including the
AutoDrive 4R90 (default) and PF-10R. The feeder
control system must be configured for both the wire
drive type and gear ratio (high or low speed range).
This can be accomplished via the Fanuc TeachPendant (V7.30p14 or later) or with the Weld
Manager Utility (included on the Power Wave Utilities

COMMON WELDING PROCEDURES
MAKING A WELD
The serviceability of a product or structure utilizing 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 selection.
The
put current of 700 amps. The allowable maximum average output
current is time dependent, but ultimately limited to 450 amps over
any 2 second period. If the maximum average is exceeded, the
output is disabled to protect the machine. Under these conditions,
normal operation can be resumed by cycling the output command.

B-7
Choose the electrode material, electrode size, shielding gas, and process (GMAW, GMAW-P etc.) appropriate for the material to be welded.
Select the weld mode that best matches the desired
welding process. The standard weld set shipped with
the Power Wave i400 encompasses a wide range of
common processes that will meet most needs. If a
special weld mode is desired, contact the local Lincoln
Electric sales representative.
To make a weld, the Power Wave i400 needs to know
the desired welding parameters. The robot controller
sends the parameters from the teach pendant (arc
voltage, wire feed speed, UltimArcTM value, etc.), to
the Power Wave i400 via the ArcLink® communication
protocol over the control, Ethernet or optional
DeviceNet cables.
OPERATION
BASIC WELDING CONTROLS
Weld Mode
Selecting a weld mode determines the output characteristics of the Power Wave i400 power source. Weld
modes are developed with a specific electrode material, electrode size, and shielding gas. For a more complete description of the weld modes programmed into
the Power Wave at the factory, refer to the Weld Set
Reference Guide supplied with the machine or available at www.powerwavesoftware.com.
B-7
In non-synergic modes, the WFS control behaves like
a conventional power source where WFS and voltage
are independent adjustments. Therefore, to maintain
proper arc characteristics, the operator must adjust
the voltage to compensate for any changes made to
the WFS.
Volts
In constant voltage modes (GMAW), this control
adjusts the welding voltage.
Trim
In pulse synergic welding modes (GMAW-P), the Trim
setting adjusts the arc length. Trim is adjustable from
0.50 to 1.50. 1.00 is the nominal setting and is a good
starting point for most conditions.
Note:
The Power Wave i400 can also be configured to
display Trim as a voltage value. This allows the
operator to pre-set an approximate welding voltage
rather than a unitless Trim value. The pre-set voltage is limited based on the process, and provides
the same range of operation as the corresponding
Trim value.
This alternate configuration is regionally enabled
based on the robot controller software. Refer to the
Fanuc documentation for manual configuration
information.
Wire Feed Speed (WFS)
In synergic welding modes (GMAW, GMAW-P), WFS
is the dominant control parameter. The user adjusts
WFS according to factors such as wire size, penetration requirements, heat input, etc. The Power Wave
then uses the WFS setting to adjust the voltage and
current according to the information contained in the
selected weld mode.
Note:
The Power Wave i400 can be configured to use
amperage as the dominant control parameter
instead of WFS for synergic welding modes. In this
configuration the user adjusts amperage according
to factors such as wire size, penetration requirements, heat input, etc. The Power Wave then uses
the amperage setting to adjust the WFS and voltage according to the information contained in the
selected weld mode.
This alternate configuration is regionally enabled
based on the robot controller software. Refer to the
Fanuc documentation for manual configuration
information.
UltimArcTM
UltimArcTM allows the operator to vary the arc characteristics from “soft” to “crisp”. UltimArcTM is
adjustable from –10.0 to +10.0 with a nominal setting
of 0.0.
CONSTANT VOLTAGE WELDING
Synergic CV
In synergic welding modes, WFS is the dominant control parameter. For each wire feed speed, a corresponding voltage is programmed into the machine at
the factory. The user adjusts WFS according to factors such as wire size, material thickness, penetration
requirements, etc. The Power Wave i400 then uses
the WFS setting to select the appropriate nominal voltage. The Power Wave i400 can also be configured to
use amperage as the dominant control parameter. In
this configuration the Power Wave i400 uses the
amperage setting to select the appropriate WFS and
nominal voltage. In either case, the user can adjust
the voltage higher or lower to compensate for material
condition or individual preference.
POWER WAVE® i400
Page 34
B-8
Non Synergic CV
In non-synergic modes, the machine behaves like a
conventional power source. The WFS and voltage
are independent adjustments. Therefore, to maintain
the arc characteristics, the operator must adjust the
voltage to compensate for any changes made to the
WFS.
UltimArcTM
UltimArcTM adjusts the apparent inductance of the
wave shape. The UltimArcTM adjustment is similar to
a “pinch” function in that it is inversely proportional to
inductance. UltimArcTM is adjustable from –10.0 to
+10.0 with a nominal setting of 0. Increasing
UltimArcTM results in a crisper, hotter arc.
Decreasing the UltimArcTM provides a softer, colder
arc.
OPERATION
Pulse Welding
When pulse welding, the power source primarily regulates the arc current, not the arc voltage. During a
pulsing cycle, arc current is regulated from a low
background level to a high peak level and then back
down to the low background level. The average arc
voltage increases and decreases as the average arc
current is increased or decreased. The peak current,
back ground current, rise time, fall time and pulse frequency all affect the average voltage. Since the average voltage for a given wire feed speed can only be
determined when all the pulsing waveform parameters
are known, a unitless value called “trim” is used for
adjusting the arc length.
B-8
Pulse welding modes are synergic; using wire feed
speed as the main control parameter. As the wire
feed speed is adjusted, the power source adjusts the
waveform parameters to maintain good welding characteristics. The Power Wave i400 can also be configured to use amperage as the dominant control parameter. In this configuration, as the amperage is
adjusted, the power source selects the appropriate
wire feed speed, and adjusts the waveform parameters to maintain good welding characteristics. In either
case, trim is used as a secondary control to change
the arc length for material conditions or individual preference.
UltimArcTM adjusts the focus or shape of the arc.
UltimArcTM is adjustable from -10.0 to +10.0 with a
nominal setting of 0.0. Increasing the UltimArcTM
increases the pulse frequency and background current while decreasing the peak current. This results in
a tight, stiff arc used for high speed sheet metal welding. Decreasing the UltimArcTM decreases the pulse
frequency and background current while increasing
the peak current. This results in a soft arc good for out
of position welding.
The Power Wave utilizes adaptive control to compensate for changes in the electrical stick-out (distance
from the contact tip to the work piece) while welding.
The Power Wave waveforms are optimized for a 5/8”
to 3/4” stick out depending on the wire type and wire
feed speed. The adaptive behavior supports a range
of stick outs from approximately ½” to 1-1/4”. At low
or high wire feed speeds, the adaptive range may be
less due to physical limitations of the welding process.
Trim adjusts the arc length and ranges from 0.50 to
1.50 with a nominal value of 1.00. Increasing the trim
value increases the arc length. Decreasing the trim
value decreases the arc length. Alternately, trim can
be displayed as a quasi-voltage value. This allows the
operator to pre-set an approximate welding voltage
rather than a unitless trim value. The pre-set voltage
is limited based on the process, and provides the
same range of operation as the corresponding trim
value.
