The Above For Gasoline Engines
FOR ENGINE
powered equipment.
1.a. Turn the engine off before troubleshooting and maintenance
work unless the maintenance work requires it to be running.
____________________________________________________
1.b. Operate engines in open, well-ventilated
areas or vent the engine exhaust fumes
outdoors.
____________________________________________________
1.c. Do not add the fuel near an open flame
welding arc or when the engine is running.
Stop the engine and allow it to cool before
refueling to prevent spilled fuel from vaporizing on contact with hot engine parts and
igniting. Do not spill fuel when filling tank. If
fuel is spilled, wipe it up and do not start
engine until fumes have been eliminated.
____________________________________________________
1.d. Keep all equipment safety guards, covers and devices in
position and in good repair.Keep hands, hair, clothing and
tools away from V-belts, gears, fans and all other moving
parts when starting, operating or repairing equipment.
____________________________________________________
1.e. In some cases it may be necessary to remove safety
guards to perform required maintenance. Remove
guards only when necessary and replace them when the
maintenance requiring their removal is complete.
Always use the greatest care when working near moving
parts.
___________________________________________________
1.f. Do not put your hands near the engine fan.
Do not attempt to override the governor or
idler by pushing on the throttle control rods
while the engine is running.
1.h. To avoid scalding, do not remove the
radiator pressure cap when the engine is
hot.
ELECTRIC AND
MAGNETIC FIELDS
may be dangerous
2.a. Electric current flowing through any conductor causes
localized Electric and Magnetic Fields (EMF). Welding
current creates EMF fields around welding cables and
welding machines
2.b. EMF fields may interfere with some pacemakers, and
welders having a pacemaker should consult their physician
before welding.
2.c. Exposure to EMF fields in welding may have other health
effects which are now not known.
2.d. All welders should use the following procedures in order to
minimize exposure to EMF fields from the welding circuit:
2.d.1.
Route the electrode and work cables together - Secure
them with tape when possible.
2.d.2. Never coil the electrode lead around your body.
2.d.3. Do not place your body between the electrode and
work cables. If the electrode cable is on your right
side, the work cable should also be on your right side.
___________________________________________________
1.g. To prevent accidentally starting gasoline engines while
turning the engine or welding generator during maintenance
work, disconnect the spark plug wires, distributor cap or
magneto wire as appropriate.
2.d.4. Connect the work cable to the workpiece as close as
possible to the area being welded.
2.d.5. Do not work next to welding power source.

ELECTRIC SHOCK can
kill.
3.a. The electrode and work (or ground) circuits
are electrically “hot” when the welder is on.
Do not touch these “hot” parts with your bare
skin or wet clothing. Wear dry, hole-free
gloves to insulate hands.
3.b. Insulate yourself from work and ground using dry insulation.
Make certain the insulation is large enough to cover your full
area of physical contact with work and ground.
In addition to the normal safety precautions, if welding
must be performed under electrically hazardous
conditions (in damp locations or while wearing wet
clothing; on metal structures such as floors, gratings or
scaffolds; when in cramped positions such as sitting,
kneeling or lying, if there is a high risk of unavoidable or
accidental contact with the workpiece or ground) use
the following equipment:
• Semiautomatic DC Constant Voltage (Wire) Welder.
• DC Manual (Stick) Welder.
• AC Welder with Reduced Voltage Control.
3.c. In semiautomatic or automatic wire welding, the electrode,
electrode reel, welding head, nozzle or semiautomatic
welding gun are also electrically “hot”.
3.d. Always be sure the work cable makes a good electrical
connection with the metal being welded. The connection
should be as close as possible to the area being welded.
3.e. Ground the work or metal to be welded to a good electrical
(earth) ground.
ARC RAYS can burn.
4.a. Use a shield with the proper filter and cover
plates to protect your eyes from sparks and
the rays of the arc when welding or observing
open arc welding. Headshield and filter lens
should conform to ANSI Z87. I standards.
4.b. Use suitable clothing made from durable flame-resistant
material to protect your skin and that of your helpers from
the arc rays.
4.c. Protect other nearby personnel with suitable, non-flammable
screening and/or warn them not to watch the arc nor expose
themselves to the arc rays or to hot spatter or metal.
FUMES AND GASES
can be dangerous.
5.a. Welding may produce fumes and gases
hazardous to health. Avoid breathing these
fumes and gases.When welding, keep
your head out of the fume. Use enough
ventilation and/or exhaust at the arc to keep
fumes and gases away from the breathing zone. When
welding with electrodes which require special
ventilation such as stainless or hard facing (see
instructions on container or MSDS) or on lead or
cadmium plated steel and other metals or coatings
which produce highly toxic fumes, keep exposure as
low as possible and below Threshold Limit Values (TLV)
using local exhaust or mechanical ventilation. In
confined spaces or in some circumstances, outdoors, a
respirator may be required. Additional precautions are
also required when welding on galvanized steel.
3.f.
Maintain the electrode holder, work clamp, welding cable and
welding machine in good, safe operating condition. Replace
damaged insulation.
3.g. Never dip the electrode in water for cooling.
3.h. Never simultaneously touch electrically “hot” parts of
electrode holders connected to two welders because voltage
between the two can be the total of the open circuit voltage
of both welders.
3.i. When working above floor level, use a safety belt to protect
yourself from a fall should you get a shock.
3.j. Also see Items 6.c. and 8.
5.b.
Do not weld in locations near chlorinated hydrocarbon
coming from degreasing, cleaning or spraying operations.
The heat and rays of the arc can react with solvent vapors
form phosgene, a highly toxic gas, and other irritating products.
5.c. Shielding gases used for arc welding can displace air and
cause injury or death. Always use enough ventilation,
especially in confined areas, to insure breathing air is safe.
5.d. Read and understand the manufacturer’s instructions for this
equipment and the consumables to be used, including the
material safety data sheet (MSDS) and follow your
employer’s safety practices. MSDS forms are available from
your welding distributor or from the manufacturer.

WELDING SPARKS can
cause fire or explosion.
6.a.
Remove fire hazards from the welding area.
If this is not possible, cover them to prevent
the welding sparks from starting a fire.
materials from welding can easily go through small cracks
and openings to adjacent areas. Avoid welding near
hydraulic lines. Have a fire extinguisher readily available.
6.b. Where compressed gases are to be used at the job site,
special precautions should be used to prevent hazardous
situations. Refer to “Safety in Welding and Cutting” (ANSI
Standard Z49.1) and the operating information for the
equipment being used.
6.c. When not welding, make certain no part of the electrode
circuit is touching the work or ground. Accidental contact
can cause overheating and create a fire hazard.
6.d. Do not heat, cut or weld tanks, drums or containers until the
proper steps have been taken to insure that such procedures
will not cause flammable or toxic vapors from substances
inside. They can cause an explosion even
been “cleaned”. For information, purchase “Recommended
Safe Practices for the
Containers and Piping That Have Held Hazardous
Substances”, AWS F4.1 from the American Welding Society
(see address above).
6.e. Vent hollow castings or containers before heating, cutting or
welding. They may explode.
Sparks and spatter are thrown from the welding arc. Wear oil
6.f.
free protective garments such as leather gloves, heavy shirt,
cuffless trousers, high shoes and a cap over your hair. Wear
ear plugs when welding out of position or in confined places.
Always wear safety glasses with side shields when in a
welding area.
6.g. Connect the work cable to the work as close to the welding
area as practical. Work cables connected to the building
framework or other locations away from the welding area
increase the possibility of the welding current passing
through lifting chains, crane cables or other alternate circuits. This can create fire hazards or overheat lifting chains
or cables until they fail.
6.h. Also see item 1.c.
Remember that welding sparks and hot
though

if damaged.
7.a. Use only compressed gas cylinders
containing the correct shielding gas for the
process used and properly operating
regulators designed for the gas and
pressure used. All hoses, fittings, etc. should be suitable for
the application and maintained in good condition.
7.b. Always keep cylinders in an upright position securely
chained to an undercarriage or fixed support.
7.c. Cylinders should be located:
• Away from areas where they may be struck or subjected to
physical damage.
• A safe distance from arc welding or cutting operations and
any other source of heat, sparks, or flame.
7.d. Never allow the electrode, electrode holder or any other
electrically “hot” parts to touch a cylinder.
7.e. Keep your head and face away from the cylinder valve outlet
when opening the cylinder valve.
7.f. Valve protection caps should always be in place and hand
tight except when the cylinder is in use or connected for
use.

PRÉCAUTIONS DE SÛRETÉ
Pour votre propre protection lire et observer toutes les instructions
et les précautions de sûreté specifiques qui parraissent dans ce
manuel aussi bien que les précautions de sûreté générales suivantes:
Sûreté Pour Soudage A L’Arc
1. Protegez-vous contre la secousse électrique:
a. Les circuits à l’électrode et à la piéce sont sous tension
quand la machine à souder est en marche. Eviter toujours
tout contact entre les parties sous tension et la peau nue
ou les vétements mouillés. Porter des gants secs et sans
trous pour isoler les mains.
b. Faire trés attention de bien s’isoler de la masse quand on
soude dans des endroits humides, ou sur un plancher
metallique ou des grilles metalliques, principalement dans
les positions assis ou couché pour lesquelles une grande
partie du corps peut être en contact avec la masse.
c. Maintenir le porte-électrode, la pince de masse, le câble
de soudage et la machine à souder en bon et sûr état
defonctionnement.
d.Ne jamais plonger le porte-électrode dans l’eau pour le
refroidir.
e. Ne jamais toucher simultanément les parties sous tension
des porte-électrodes connectés à deux machines à souder
parce que la tension entre les deux pinces peut être le
total de la tension à vide des deux machines.
f. Si on utilise la machine à souder comme une source de
courant pour soudage semi-automatique, ces precautions
pour le porte-électrode s’applicuent aussi au pistolet de
soudage.
6. Eloigner les matériaux inflammables ou les recouvrir afin de
prévenir tout risque d’incendie dû aux étincelles.
7. Quand on ne soude pas, poser la pince à une endroit isolé de
la masse. Un court-circuit accidental peut provoquer un
échauffement et un risque d’incendie.
8. S’assurer que la masse est connectée le plus prés possible
de la zone de travail qu’il est pratique de le faire. Si on place
la masse sur la charpente de la construction ou d’autres
endroits éloignés de la zone de travail, on augmente le risque
de voir passer le courant de soudage par les chaines de levage, câbles de grue, ou autres circuits. Cela peut provoquer
des risques d’incendie ou d’echauffement des chaines et des
câbles jusqu’à ce qu’ils se rompent.
9. Assurer une ventilation suffisante dans la zone de soudage.
Ceci est particuliérement important pour le soudage de tôles
galvanisées plombées, ou cadmiées ou tout autre métal qui
produit des fumeés toxiques.
10. Ne pas souder en présence de vapeurs de chlore provenant
d’opérations de dégraissage, nettoyage ou pistolage. La
chaleur ou les rayons de l’arc peuvent réagir avec les vapeurs
du solvant pour produire du phosgéne (gas fortement toxique)
ou autres produits irritants.
11. Pour obtenir de plus amples renseignements sur la sûreté,
voir le code “Code for safety in welding and cutting” CSA
Standard W 117.2-1974.
2. Dans le cas de travail au dessus du niveau du sol, se protéger
contre les chutes dans le cas ou on recoit un choc. Ne jamais
enrouler le câble-électrode autour de n’importe quelle partie
du corps.
3. Un coup d’arc peut être plus sévère qu’un coup de soliel,
donc:
a. Utiliser un bon masque avec un verre filtrant approprié
ainsi qu’un verre blanc afin de se protéger les yeux du rayonnement de l’arc et des projections quand on soude ou
quand on regarde l’arc.
b. Porter des vêtements convenables afin de protéger la
peau de soudeur et des aides contre le rayonnement de
l‘arc.
c. Protéger l’autre personnel travaillant à proximité au
soudage à l’aide d’écrans appropriés et non-inflammables.
4. Des gouttes de laitier en fusion sont émises de l’arc de
soudage. Se protéger avec des vêtements de protection libres
de l’huile, tels que les gants en cuir, chemise épaisse, pantalons sans revers, et chaussures montantes.
5. Toujours porter des lunettes de sécurité dans la zone de
soudage. Utiliser des lunettes avec écrans lateraux dans les
zones où l’on pique le laitier.
PRÉCAUTIONS DE SÛRETÉ POUR
LES MACHINES À SOUDER À
TRANSFORMATEUR ET À
REDRESSEUR
1. Relier à la terre le chassis du poste conformement au code de
l’électricité et aux recommendations du fabricant. Le dispositif
de montage ou la piece à souder doit être branché à une
bonne mise à la terre.
2. Autant que possible, I’installation et l’entretien du poste seront
effectués par un électricien qualifié.
3. Avant de faires des travaux à l’interieur de poste, la debrancher à l’interrupteur à la boite de fusibles.
4. Garder tous les couvercles et dispositifs de sûreté à leur
place.

• Dirt and dust that can be drawn into the machine
should be kept to a minimum. Failure to observe
these precautions can result in excessive operating
temperatures and nuisance shutdown.
• Keep machine dry. Shelter from rain and snow. Do
not place on wet ground or in puddles.
A-2
• Initial 380VAC - 415VAC and 575VAC operation
will require an Input voltage panel setup.
• Open the front door to access “A” lead.
• Move the "A" lead to the appropriate terminal.
CAUTION
• Incorrect connection may result in equipment
damage.
-----------------------------------------------------------------------

INSTALLATION
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.
CAUTION
A-3
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. Set the Negative Polarity switch on Wire Feed Head PC
board as follows:
WARNING
ELECTRIC SHOCK can kill
• Turn the input power OFF at the disconnect switch or fuse box before
working on this equipment.
When using an inverter type power source like the
Power Waves, 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 electrode 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 contact. The electrode cable should be sized according to
the specifications given in the output cable connections 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 electrode and work cable set-up, See the standard "SAFETY 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.
• Do not touch electrically hot parts.
-----------------------------------------------------------
1. Turn off power to the power source at the disconnect
switch.
2. Remove the front cover from the power source.
3. The feed head PC board is on the left side of the power
source. Locate the 8-position DIP switch and look for
switch 7 of the DIP switch.(See Figure A.1)
4. Using a pencil or other small object, slide the switch to
the OFF position for positive electrode polarity.
Conversely, slide the switch to the ON position for negative electrode polarity.
5. Replace the cover and screws. The PC board will“read”
the switch at power up, and configure the work voltage
sense lead appropriately.
VOLTAGE SENSING
The best arc performance occurs when the PowerWaves
have accurate data about the arc conditions. Depending
upon the process, inductance within the electrode and work
lead cables can influence the voltage apparent at the studs
of the welder. Voltage sense leads improve the accuracy of
the arc conditions and can have a dramatic effect on performance. Sense Lead Kits (K940-10, -25 or -50) are available
for this purpose.
CAUTION
If the voltage sensing is enabled but the sense
leads are missing, improperly connected, or if the
electrode polarity switch is improperly configured,
extremely high welding outputs may occur.
------------------------------------------------------------------------
The ELECTRODE sense lead (67) is built into the control
cable, and is automatically enabled for all semi-automatic
processes. The WORK sense lead (21) connects to the
Power Wave at the four pin connector. By default the
WORK voltage is monitored at the output stud in the
POWER WAVE F355i. For more information on the WORK
sense lead (21), see"Work Voltage Sensing” in the follow-
ing paragraph.

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.
* The electrode voltage 67 sense lead is integral to the
control cable to the wire feeder.
Work Voltage Sensing
The standard POWER WAVE F355i’s 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:
WARNING
ELECTRIC SHOCK can kill
• Turn the input power OFF at the
disconnect switch or fuse box
before working on this equipment.
-----------------------------------------------------------
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.
(See Figure A.1)
.
CAUTION
Important: The electrode polarity must be configured on the feed head PC board. Failure to do so
may result in extremely high welding outputs.

POWER WAVE / POWER FEED WIRE
FEEDER INTERCONNECTIONS
(See Section F-2 for Connection Diagram)
Connect the control cable between the power source
and wire feeder. The wire feeder connection on the
Power Wave F355i is the 14-pin connector located on
the left side of the machine. The control cable is
keyed and polarized to prevent improper connection.
CONTROL CABLE SPECIFICATIONS
It is recommended that genuine Lincoln control cables
be used at all times. Lincoln cables are specifically
designed for the communication and power needs of
the Power Wave / Power Feed system.
CAUTION
The use of non-standard cables, especially in
lengths greater than 25 feet, can lead to communication problems (system shutdowns), poor motor
acceleration (poor arc starting) and low wire driving force (wire feeding problems).
HIGH SPEED GEAR BOX
Changing the ratio requires a gear change and a PC
board switch change. The Power Feed Wire Feeders
are shipped with both high speed and a low speed
gears. As shipped from the factory, the low speed
(high torque) gear is installed on the feeder. To
change Gear ratio see Power Feed 10/R Instruction
Manual.
