WARNING
ARC WELDING can be hazardous.
PROTECT YOURSELF AND OTHERS FROM POSSIBLE SERIOUS INJURY OR DEATH. KEEP CHILDREN
AWAY. PACEMAKER WEARERS SHOULD CONSULT WITH THEIR DOCTOR BEFORE OPERATING.
Read and understand the following safety highlights. For additional safety information it is strongly recommended that you
purchase a copy of “Safety in Welding & Cutting - ANSI Standard Z49.1” from the American Welding Society, P.O. Box 351040,
Miami, Florida 33135 or CSA Standard W117.2-1974. A Free copy of “Arc Welding Safety” booklet E205 is available from the
Lincoln Electric Company, 22801 St. Clair Avenue, Cleveland, Ohio 44117-1199.
BE SURE THAT ALL INSTALLATION, OPERATION, MAINTENANCE, AND REPAIR PROCEDURES ARE
PERFORMED ONLY BY QUALIFIED INDIVIDUALS.
ELECTRIC SHOCK can
kill.
1.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.
1.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.
1.c. In semiautomatic or automatic wire welding, the electrode,
electrode reel, welding head, nozzle or semiautomatic
welding gun are also electrically“hot”.
1.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.
1.e. Ground the work or metal to be welded to a good electrical
(earth) ground.
1.f. Maintain the electrode holder, work clamp, welding cable and
welding machine in good, safe operating condition. Replace
damaged insulation.
1.g. Never dip the electrode in water for cooling.
1.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.
1.i. When working above floor level, use a safety belt to protect
yourself from a fall should you get a shock.
1.j. Also see Items 4.c. and 6.
ARC RAYS can burn.
2.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.
2.b. Use suitable clothing made from durable flame-resistant
material to protect your skin and that of your helpers from
the arc rays.
2.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.
3.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.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
products.
3.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.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.e. Also see item 7b.
WELDING SPARKS can
cause fire or explosion.
4.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.
4.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.
4.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.
4.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).
4.e. Vent hollow castings or containers before heating, cutting or
welding. They may explode.
Apr. ‘93

4.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.
4.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.
4.h. Also see item 7c.
7.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.
7.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.
CYLINDER may explode
if damaged.
5.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.
5.b. Always keep cylinders in an upright position securely
chained to an undercarriage or fixed support.
5.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.
5.d. Never allow the electrode, electrode holder or any other
electrically “hot” parts to touch a cylinder.
5.e. Keep your head and face away from the cylinder valve outlet
when opening the cylinder valve.
5.f. Valve protection caps should always be in place and hand
tight except when the cylinder is in use or connected for
use.
5.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.
FOR ELECTRICALLY
powered equipment.
6.a. Turn off input power using the disconnect
switch at the fuse box before working on
the equipment.
6.b. Install equipment in accordance with the U.S. National
Electrical Code, all local codes and the manufacturer’s
recommendations.
6.c. Ground the equipment in accordance with the U.S. National
Electrical Code and the manufacturer’s recommendations.
FOR ENGINE
powered equipment.
7.a. Turn the engine off before troubleshooting and maintenance
work unless the maintenance work requires it to be running.
7.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.
7.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.
7.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.
7.h. To avoid scalding, do not remove the
radiator pressure cap when the engine is
hot.
ELECTRIC AND MAGNETIC FIELDS
may be dangerous
8.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.
8.b. EMF fields may interfere with some pacemakers, and
welders having a pacemaker should consult their physician
before welding.
8.c. Exposure to EMF fields in welding may have other health
effects which are now not known.
8d. All welders should use the following procedures in order to
minimize exposure to EMF fields from the welding circuit:
8.d.1. Route the electrode and work cables together - Secure
them with tape when possible.
8.d.2. Never coil the electrode lead around your body.
8.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.
8.d.4. Connect the work cable to the workpiece as close as
possible to the area being welded.
8.d.5. Do not work next to welding power source.
7.b. Operate engines in open, well-ventilated
areas or vent the engine exhaust fumes
outdoors.
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
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.

mounting bracket attached to the bottom of the
gearbox. Reference L9777 dimension print at the rear
of this manual to find the size and location of the
mounting holes. The gearbox assembly is electrically
“hot” when the gun trigger is pressed. Therefore,
make certain the gearbox does not come in contact
with the structure on which the unit is mounted.

on the front of the wire feed unit.
connector of the cable to the mating receptacle on
the bottom of the control box.
The wire feed unit should be mounted so that the
drive rolls are in a vertical plane so dirt will not collect
in the drive roll area. Position the mechanism so it will
point down at about a 45° angle so the wire feed gun
cable will not be bent sharply as it comes from the
unit.
Mounting the Control Box (K678-1)
The same control box is used for both the Synergic 7F
and Synergic 7FH wire feed units and contains two
keyhole slots and one slot for mounting. Reference
M17740 dimension print in the rear of this manual for
size and location of these slots. Mount the box at
some convenient location close to the wire feed unit
which will enable the desired control cable assembly
to reach between the control box and the wire feed
unit.
a) Drill the required holes in the mounting surface,
partially install 1/4-20 screws.
Electrode Routing
The electrode supply may be either from reels, ReadiReels, spools or bulk packaged drums or reels.
Observe the following precautions:
1. The electrode must be routed to the wire feed unit
so that the bends in the wire are at a minimum,
and also that the force required to pull the wire
from the reel into the wire feed unit is kept at a
minimum.
2. The electrode is “hot” when the gun is energized
and must be insulated from the boom and
structure.
3. If more than one wire feed unit shares the same
boom, their wire and reels must be insulated from
each other and insulated from their mounting
structure.

solenoid valve, then the wire feeder
and the power source after Preflow
time (See Timer/ Crater Section).
2. Releasing the trigger turns off the
wire feeder and power source and
then the solenoid valve after
Postflow time.
Observe all additional Safety Guidelines detailed
throughout this manual.
Duty Cycle
The Synergic 7F models are rated at 60% duty cycle
* for a maximum current of 600 amps.
* Based on a 10 minute time period (6 minutes on, and 4 minutes off).
KEYPAD SETUP AND OPERATION
Power-Down Save
Power to the Synergic 7F is supplied and controlled
from the power source. The Synergic 7F
automatically senses the loss of power when the
power source is turned off.
Procedure settings, including mode, crater speed,
cold feed speed , run-in speed, weld speed, timers
and acceleration are automatically saved when power
is removed. Arc Voltage setting is retained by the
synergic power source. This feature does not require
batteries and when power is restored it will
automatically return all settings to the state they were
in when power was removed. The power source may
automatically overwrite any or all of these settings
following power-up recall.
Operation Keys
Cold Feed key energizes the wire
feeder but not the power source or
solenoid valve. This cold feed
speed is digitally displayed and is

Middle Light - Indicates 4-Step (Lock)
Trigger Mode. These models have selectable
4-step with crater fill or, as shipped, 4-step
with current interlock. (See 4-step trigger
mode selection for method of switching).
The 4-step modes function as follows:
1. Trigger closure energizes the power
source and wirefeeder after the
preflow time.
2. Trigger release enables 4-step lock,
leaving the feeder and power source
as in step 1.
a) 4-step with current interlock will only
lock if weld current is flowing.
Breaking weld arc stops wire feed
and power source output.
b) 4-step with crater fill will lock without
welding.
3. Closing the trigger a second time
continues welding.
a) 4-step with current interlock
continues welding without changing
the settings from step 2.
b) 4-step with crater fill continues
welding but changes to the crater
settings.
4. Releasing the trigger turns off
wirefeeder and power source and
then gas solenoid after postflow
time.
Bottom Light - Indicates Spot Weld
Mode. Trigger closure energizes the
solenoid valve, then wire feeder and
the power source. The spot on timer
starts when current flows. The wire
feeder and power source then
solenoid valve are all turned off when
the spot on timer times out even
through the trigger is still closed.

TYPE ADAPTER:
To Mount 10 to 44 lb (4.5-20kg) Spool
(12”/300mm Diameter): (Requires installation
of 2” (51mm) spindle K162H Kit. For 8” (200mm)
spools, a K468 spindle adapter must be used.)
1) Remove the locking collar on the 2” (51mm)
diameter spindle.
2) Place the spool on the spindle making certain the
brake holding pin enters one of the holes in the
back side of the spool. Be certain the wire comes
off the reel in a clockwise direction when de-reeled
from the bottom of the coil.
3) Replace and tighten the locking collar.
Feeding Electrode and Brake Adjustment
1) Turn the Readi-Reel or spool until the free end of
the electrode is accessible.
WARNING
1) Make certain that the threaded locking collar is
tight and securely locks the adapter on the spindle
(see figure above).
2) Rotate the spindle and adapter so the retaining
spring is at the 12 o’clock position.
3) Position the Readi-Reel so that it will rotate in a
clockwise direction when feeding (wire is to be dereeled from bottom of the coil).
4) Set one of the Readi-Reel inside cage wires on the
slot in the retaining spring tab.
5) Lower the Readi-Reel to depress the retaining
spring and align the other inside cage wires with
the grooves in the molded adapter.
6) Slide cage all the way onto the adapter until the
retaining spring “pops up” fully.
When feeding with the gun trigger, the electrode and
drive mechanism are always “HOT” to work and
ground and could remain “HOT” several seconds after
the gun trigger is released.
___________________________________________
2) While tightly holding the electrode, cut off the bent
end and straighten the first 6” (150mm). Cut off
the first 1” (25mm). (If the electrode is not properly
straightened, it may not feed or may not go into
the outgoing guide tube causing a “birdnest”.)
3) Insert the free end through the incoming guide
tube.
4) Press the Cold Inch key or the gun trigger and
push the electrode into the drive roll.
5) Feed the electrode through the gun.
6) Adjust the brake tension with the thumbscrew on
the spindle hub, until the reel turns freely but with
little or no overrun when wire feeding is stopped.
Do not overtighten.
The mount for standard 50-60 lb (22.7-27.2 kg)
electrode coils includes a two-position brake
assembly. Generally the brake should be at the inner
position (nearest to the wire reel shaft) for wire feed
speeds below 400 in/min. (10m/m). It should be at the
outer position for the faster wire speeds often used
when feeding small diameter electrode.
To adjust the brake position, remove the wire reel.
Pull the cotter pin that holds the brake shoe to the
arm, move the shoe and replace the cotter pin. Do
not bend the cotter pin - it is held in place by a friction
fit.
To Mount a 50-60lb (22.7-27.2kg) Coil:
1) To remove the wire reel from its shaft, grasp the
spring loaded knob and pull it out. This straightens
the knob so it seats into the shaft when released.
Remove the reel.
5) Cut and remove only the tie wire holding the free
end of the coil. Insert the free end into one of the
holes in the cover and secure it by bending it back.
Cut and remove the remaining tie wires.
CAUTION
Always be sure the free end of the coil is securely
held while the tie wires are being cut and until the wire
is feeding through the drive rolls. Failure to do this will
result in “backlashing” of the coil, which may tangle
the wire. A tangled coil will not feed so it must either
be untangled or discarded.
___________________________________________
6) Replace the reel on the wire feeder. Grasp the
shaft knob, pull it out and swing it across the reel
hub, locking the reel in place.
Feeding Electrode
1) Turn the reel until the free end of the electrode is
accessible. While tightly holding the electrode, cut
off the bent end.
2) Lay the reel flat on the floor, loosen the spinner nut
and remove the cover plate.
3) Before cutting the tie wires, place the coil of
electrode on the reel so it unwinds as the reel
rotates clockwise.
a) Be sure the coil is placed so the spring loaded
arms will not interfere with the later removal of
the coil tie wires (see illustration below).
b) When loading .030-.045” (0.8-1.2mm)
electrode, be certain the coil is placed on the
reel so the spring loaded arms are at the center
of the slots in the cardboard coil liner. This
provides the positive compression of the coil
sides needed for trouble-free wire feeding (see
illustration).
c) Put the cover plate on the reel so that the four
arms of the cover straddle and are in line with
the spring loaded arm of the reel proper.
2) Straighten the first 6” (150mm) and cut off the first
1” (25mm). Insert the free end through the incoming
guide tube. Press the Cold Inch key or the gun trigger
and push the electrode into the drive roll. Feed the
electrode through the gun. (If the electrode is not
properly straightened, it may not feed or may not go
into the outgoing guide tube causing a “birdnest”.)
WARNING
When feeding with the gun trigger, the electrode and
drive mechanism are always “HOT” to work and
ground and could remain “HOT” several seconds after
the gun trigger is released.

Wire Loading of 13-14lb (6kg) Innershield
Coils
Requires use of K162H Spindle Kit and K435 14 Lb.
Coil Adapter.
Idle Roll Pressure Setting
The idle roll pressure is set at the factory, backed out
three turns from full pressure on 4-roll feeders. This is
an approximate setting. For small wire sizes and
aluminum wire up to 9 or 10 turns out may be required
to minimize “birdnesting”. The optimum idle roll
pressure varies with type of wire, surface condition,
lubrication, and hardness. The optimum idle roll
setting can be determined as follows:
1) Release the incoming idle roll pressure arm, then
press end of gun against a solid object that is
electrically isolated from the welder output and
press the gun trigger for several seconds.
2) If the wire “birdnests”, jams, or breaks at the drive
roll, the idle roll pressure is too great. Back the
pressure setting out 1/2 turn, run new wire through
gun, and repeat above steps.
3) If the only result is drive roll slippage, disengage
the gun locking nut, and pull the gun cable forward
about 6” (150mm). There should be a slight
waviness in the exposed wire. If there is no
waviness, the pressure is too low. Increase the
pressure setting 1/4 turn, reconnect the gun,
tighten the locking nut, and repeat the above
steps.
4) After the outgoing pressure is set, determine how
many turns away from full pressure the setting is.
Set both idle roll tensions to this setting. Engage
both idle rolls before welding. In most applications,
best wire feeding will occur when both idle roll
pressures are set the same.
Gas Guard Regulator Setting (Optional
K659-1)
1) With the gas supply shut off, the Gas Guard
regulator flow adjusting key should be set to
maximum (full clockwise) which is rated to be 60
SCFH (28 lts/ min).
2) Adjust gas supply flow rate for a level higher than
will be required, then adjust Gas Guard flow
adjusting key counterclockwise to the desired gas
flow rate.

Making a Weld
1) Use only Power Wave model “synergic” power
sources.
2) Properly connect the electrode and work leads for
the correct electrode polarity.
3) Use Mode Selection key to set desired operating
mode. (Refer to Mode Selection section.)
13) If necessary to optimize arc starting, adjust wire
speed acceleration, and/or Run-In speed. (See the
appropriate sections for adjusting procedures).
Wire Reel Changing
At the end of a coil, remove the last of the old
electrode coil from the conductor cable by either
pulling it out at the nozzle end of the gun or by using
the following procedure:
4) Use Function Select and Arrow keys to set desired
Run-in and encoder knob to set Weld Feed
Speeds. (Set for each procedure if using optional
Dual Procedure Switch).
5) Adjust the voltage or percent trim, if desired, (for
each procedure if using the optional Dual
Procedure Switch) using the encoder knob in
“Volts/Trim” function (refer to Volts/Trim section).
The final setting can be adjusted according to the
desired arc voltage while welding.
6) Use Timer/Crater Select and Arrow keys to set
desired timers, or crater speed if 4-step trigger with
Crater fill has been selected. (Refer to the
Timer/Crater section).
7) Feed the electrode through the gun and cable and
then cut the electrode within approximately
.38” (9.5mm) of the end of the contact tip for solid
wire, and within approximately .75” (19mm) of the
extension guide for cored wire.
8) Connect work cable to metal to be welded. Work
cable must make good electrical contact to the
work. The work must also be grounded as stated
in “Arc Welding Safety Precautions”.
WARNING
When using an Open Arc process,
it is necessary to use correct eye,
head, and body protection
____________________________________
9) If used, be sure shielding gas valve is turned on.
10) Position electrode over joint. End of electrode
may be lightly touching the work.
1) Cut the end of the electrode off at the gun end. Do
not break it off by hand because this puts a slight
bend in the wire making it difficult to pull it back
through the nozzle.
2) Disconnect the gun cable from the gun connector
on the Synergic 7F Wire Feed Unit and lay the gun
and cable out straight.
3) Using pliers to grip the wire, pull it out of the cable
from the connector end.
4) After the electrode has been removed, reconnect
the gun cable to the Synergic 7F.
Load a new reel of electrode per the instructions in
the Wire Reel Loading sections.
Wire Feed Overload Protection
The Synergic 7F has solid-state overload protection of
the wire drive motor. If the wire drive motor becomes
overloaded for an extended period of time, the
protection circuitry turns off the power source, wire
feed and solenoid and then displays H30. This
indicates the wire drive motor is overloaded and the
number indicates the time remaining in seconds
before the unit will automatically reset. The number
continues to decrement every second until it
reaches 0. At that time, the unit resets automatically
and the previous display will return indicating the unit
is ready to operate again. Overloads can result from
improper tip size, liner, drive rolls, or guide tubes,
obstructions or bends in the gun cable, feeding wire
that is larger than the rated capacity of the feeder or
any other factors that would impede normal wire
feeding. (See section on Avoiding Wire Feeder
Problems.)
11) Lower welding helmet, close gun trigger and start
welding. Hold the gun so the contact tip to work
distance gives the correct electrical stickout as
required for the procedure being used.
12) To stop welding, release the gun trigger and then
pull the gun away from the work after the arc
goes out and Postflow time, if used, is over.

To prolong the life of the reel shaft, periodically coat it
with a thin layer of grease.
ELECTRIC SHOCK can kill.
• Do not touch electrically live parts such
as output terminals or internal wiring.
• When inching with gun trigger, electrode
and drive mechanism are “hot” to work
and ground.
• Turn OFF welding power source before
installing or changing drive roll and/or
guide tubes.
• Welding power source must be connected

codes.
• Only qualified personnel should do
maintenance or troubleshooting work.
Observe all additional Safety Guidelines detailed
throughout this manual.
Routine Maintenance
Drive Rolls and Guide Tubes
After feeding every coil of wire, inspect the drive roll
section. Clean it as necessary. Do not use a solvent
for cleaning the idle roll because it may wash the
lubricant out of the bearing. The driver roll and guide
tubes are stamped with the wire sizes they will feed.
If a wire size other than that stamped on the roll(s) is
to be used, the roll(s) and guide tubes must be
changed.
No maintenance of the two-position adjustable brake
is needed. If the brake shoe wears through to the
metal, replace the brake assembly.
Wire Reel Mounting - Readi-Reels and
10 through 30lb (4.5-14kg) Spools
No routine maintenance required. Do not lubricate 2”
(51mm) spindle.
Avoiding Wire Feeding Problems
Wire feeding problems can be avoided by observing
the following gun handling procedures:
a) Do not kink or pull cable around sharp corners.
b) Keep the electrode cable as straight as possible
when welding or loading electrode through cable.
c) Do not allow dolly wheels or trucks to run over
cables.
d) Keep cable clean by following maintenance
instructions.
e) Use only clean, rust-free electrode. The Lincoln
electrodes have proper surface lubrication.
The drive rolls for .035” (0.9mm) through .052”
(1.3mm) cored electrode and 1/16” (1.6mm) through
3/32” (2.4mm) electrode have a double set of teeth so
they can be reversed for additional life. Drive rolls for
.023" (0.6 mm) through .052" (1.3 mm) solid
electrodes and aluminum sizes have no teeth, but use
two grooves so they also can be reversed for
additional life.
See section on Wire Feed Drive Roll and Guide Tube
Kits for roll changing instructions.
f) Replace contact tip when the arc starts to become
unstable or the contact tip end is fused or
deformed.
g) Do not use excessive wire spindle brake settings.
Periodic Maintenance

The Procedure Handbook of Arc Welding
With over 500,000 copies of previous editions published
since 1933, the Procedure Handbook is considered by many to
be the “Bible” of the arc welding industry.
This printing will go fast so don’t delay. Place your
order now using the coupon below.
The hardbound book contains over 750 pages of welding
information, techniques and procedures. Much of this material
has never been included in any other book.
A must for all welders, supervisors, engineers and
designers. Many welding instructors will want to use the book
as a reference for all students by taking advantage of the low
quantity discount prices which include shipping by
4th class parcel post.
$15.00 postage paid U.S.A. Mainland
How To Read Shop Drawings
The book contains the latest information and application
data on the American Welding Society Standard Welding
Symbols. Detailed discussion tells how engineers and
draftsmen use the “short-cut” language of symbols to pass
on assembly and welding information to shop personnel.
New Lessons in Arc Welding
Lessons, simply written, cover manipulatory techniques;
machine and electrode characteristics; related subjects,
such as distortion; and supplemental information on arc
welding applications, speeds and costs. Practice materials,
exercises, questions and answers are suggested for each
lesson.
528 pages, well illustrated, 6” x 9” size, bound in simulated,
