WARNING
Mar ‘95
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.
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.
1.h. To avoid scalding, do not remove the
radiator pressure cap when the engine is
hot.

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.
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.
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.
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.
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.
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.

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.
•Asafe 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.
Mar ‘95
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.
Remember that welding sparks and hot
materials from welding can easily go through small cracks
and openings to adjacent areas. Avoid welding near
hydraulic lines. Have a fire extinguisher readily available.
6.b. Where compressed gases are to be used at the job site,
special precautions should be used to prevent hazardous
situations. Refer to “Safety in Welding and Cutting” (ANSI
Standard Z49.1) and the operating information for the
equipment being used.
6.c. When not welding, make certain no part of the electrode
circuit is touching the work or ground. Accidental contact can
cause overheating and create a fire hazard.
6.d. Do not heat, cut or weld tanks, drums or containers until the
proper steps have been taken to insure that such procedures
will not cause flammable or toxic vapors from substances
inside. They can cause an explosion even 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).
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.
6.g. Connect the work cable to the work as close to the welding
area as practical. Work cables connected to the building
framework or other locations away from the welding area
increase the possibility of the welding current passing
through lifting chains, crane cables or other alternate circuits.
This can create fire hazards or overheat lifting chains or
cables until they fail.

PRÉCAUTIONS DE SÛRETÉ
Pour votre propre protection lire et observer toutes les instructions
et les précautions de sûreté specifiques qui parraissent dans ce
manuel aussi bien que les précautions de sûreté générales suiv-
antes:
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 met-
allique 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 defonc-
tionnement.
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.
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 rayon-
nement 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, pan-
talons sans revers, et chaussures montantes.
5. Toujours porter des lunettes de sécurité dans la zone de
soudage. Utiliser des lunettes avec écrans lateraux dans les
zones où l’on pique le laitier.
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.
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.

OUTPUT CABLES, CONNECTIONS AND
LIMITATIONS
Connect a work lead of sufficient size and length
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 or wire feeder. Avoid excessive
lengths and do not coil excess cable.
When using an inverter type power source like the
PowerWaves, use the largest welding (electrode
and work) cables that are practical. At least 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
welding characteristics, if undersized welding
cables are used.
------------------------------------------------------------------------
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 Twist-Mate terminal on the power source.
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 connection to the
feed plate makes tight metal-to-metal electrical con-
tact. The electrode cable should be sized according to
the specifications given in the output cable connec-
tions section. Connect a work lead from the negative
(-) power source output Twist-Mate terminal to the work
piece. The work piece connection must be firm and
secure, especially if pulse welding is planned.
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.
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, reverse the output
connections at the power source (electrode cable to
the negative (-) Twist-Mate terminal, and work cable
to the positive (+) Twist-Mate terminal.
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.
VOLTAGE SENSING
The best arc performance occurs when the
PowerWaves have accurate data about the arc condi-
tions. 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 condi-
tions and can have a dramatic effect on performance.
Sense Lead Kits (K940-10, -25 or -50) are available for
this purpose.
CAUTION
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.
------------------------------------------------------------------------
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 at the four pin connector. By
default the WORK voltage is monitored at the output
stud in the POWER WAVE 355/405. For more infor-
mation on the WORK sense lead (21), see"Work
Voltage Sensing” in the following paragraph.

Work Voltage Sensing
The standard POWER WAVE 355/405 default to the
work stud (work sense lead disabled)
For processes requiring work voltage sensing, connect
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 current
path. Enable the work voltage sensing in the Power
Wave as follows:
• Do not touch electrically live parts or
electrodes with your skin or wet
clothing.
• 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 wrap around cover from the power
source.
3. The control board is on the center assembly facing
the case front. 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.
WARNING
O
N12345678
5. Replace the wrap around 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.
CAUTION
Important: The electrode polarity must be config-
ured at the feed head for all semi-automatic
processes. Failure to do so may result in extreme-
ly high welding outputs.
------------------------------------------------------------------------
POWER WAVE TO SEMI-AUTOMATIC
POWERFEED WIRE FEEDER INTERCON-
NECTIONS
The POWER WAVE 355/405 and semi-automatic
PowerFeed family communicate via a 5 conductor con-
trol cable (K1543). The control cable consists of two
power leads, one twisted pair for digital communica-
tion, 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 405
is on 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.
Due to the flexibility of the platform the configuration
may vary. The following is a general description of the
system. For specific configuration information, consult
the semi-automatic Power Feed instruction manual.

SYSTEM DESCRIPTION
The POWER WAVE 355/405 and Power Feed 10/11
family of products utilize a digital communication sys-
tem called Linc-Net. Simply put, Linc-Net 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.
Each "system" must contain only one power source.
The power source may be connected to a maximum of
four feeder groups. Each group containing one user
interface (UI), and up to seven Feed Heads (FH). SEE
FIGURE A.1. The UI controls all of the FH’s of that
group. The UI’s and FH’s are assigned to groups by
setting a code on the DIP switches mounted on their
individual control boards. For example all of the FH’s to
be controlled by a given UI must have their "Group ID"
switches set to the same group number as the UI. In
addition, each FH must be assigned a separate FH
number within that group. See the system set-up sec-
tion for further details.
From a network perspective, each component in the
system is considered a separate node, regardless of
its physical location. For example, even though a UI
and FH may be physically mounted together, they are
still viewed as separate pieces (nodes) by the network,
and can only communicate via Linc-Net. The Linc-Net
connection is generally made external through the
Linc-Net Control Cable, but can also be made internal-
ly, as with the PF-10 bench model feeder.
The most common Linc-Net configuration (called a
simple system) consists of one power source, one user
interface and one feeder. Under these circumstances
the group and feed head ID DIP switches are ignored
and the system will function regardless of their posi-
tion. The same is true for the minimum system con-
sisting of a power source and one UI (Example: a stick
welding system).

SYSTEM SET-UP
Basic Rules
• Each group is required to have one user interface. No
group may have more than one user interface.
• Each group can have up to seven Feed Heads.
Exception: Group 3 is limited to a maximum of six
Feed Heads.
• Each system has only one power source. For network
purposes, the PS belongs to Group 3, which is why
group 3 is only allowed 6 feed heads in addition it’s
user interface.
• No two feed heads can have identical Group and
Feed Head numbers.
• Group and Feed Head ID numbers must be set on
the appropriate dip switches at each node. Consult
the PF-10/11 Instruction Manual for specific details
regarding dip switch settings.
• Feed head “0” not allowed. Exception: Simple sys-
tem ignores all ID numbers, therefore “FH0” will func-
tion.
• Each node must be connected to the Linc-Net com-
munication network. The order of connection is not
important, as each node is identified by it’s unique
Group and Feed Head ID number as defined on it’s
dip switches. See Figures A.2 thru A.5.

WELDING WITH MULTIPLE POWER
WAVES
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.
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 directions
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 puls-
ing 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.6)
CAUTION
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.
The use of non-standard cables, especially in
lengths greater than 25 feet, can lead to communi-
cation problems (system shutdowns), poor motor
acceleration (poor arc starting) and low wire dri-
ving 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.

DIP SWITCH SETTINGS AND LOCATIONS
DIP switches on the P.C. Boards allow for custom con-
figuration of the Power Wave. To access the DIP
switches:
1. Turn off power to the power source at the dis-
connect switch.
------------------------------------------------------------------------
2. Remove the wrap around cover from the power
source.
3. The control board is on the center assembly facing
the case front. 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 wrap around and screws. The PC board
will “read” the switch at power up, and configure the
work voltage sense lead appropriately.
