cancer, birth defects, or other reproductive harm.
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.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. 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.

cause fire or explosion.
6.a.
Remove fire hazards from the welding area.
If this is not possible, cover them to prevent
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

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.
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,
voir le code “Code for safety in welding and cutting” CSA
Standard W 117.2-1974.
PRÉCAUTIONS DE SÛRETÉ POUR
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.
LES MACHINES À SOUDER À
TRANSFORMATEUR ET À
REDRESSEUR
1. Relier à la terre le chassis du poste conformement au code de
lʼélectricité 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, Iʼinstallation et lʼentretien du poste seront
effectués par un électricien qualifié.
3. Avant de faires des travaux à lʼinterieur de poste, la debrancher à lʼinterrupteur à la boite de fusibles.
4. Garder tous les couvercles et dispositifs de sûreté à leur
place.

Mounting the 10 Series Wire Drive Unit
Mount the 10 Series wire drive unit to the boom or
structure using the four 5/16-18 threaded mounting
holes located on the bottom of the drive connection
box. See Figure A.1 for the size and location of the
mounting holes. The feed plate and cover assembly is
electrically "hot" when the gun trigger is pressed.
Therefore, make certain the feed plate and cover do
not come in contact with the structure on which the
unit is mounted.
The wire drive unit should be mounted so that the
drive rolls are in a vertical plane so dirt will not collect
in the drive roll area. Pivot the feed plate so it will
point down at an angle so the wire feed gun cable will
not be bent sharply as it comes from the unit. See
“Procedure for setting angle of Feed Plate” in the
OPERATION section of this manual.

direction.
b) Loosen the retaining screw, which is also
accessed from bottom of feeder, using a 3/16"
Allen wrench. Continue to loosen the screw
until the feedplate can be easily pulled off of the
wire feeder.
3) Loosen, but do not remove, the screw on the lower right
face of the feedplate with a 3/16" Allen wrench.
4) Remove the screw on the left face of the feedplate. If
changing from high speed (larger gear) to low speed
(smaller gear), line the lower hole on the left face of the
feedplate with the threads on the clamping collar. Line
the upper hole with the threads to install larger gear for
high speed feeder. If feedplate does not rotate to allow
holes to line up, further loosen the screw on right face of
feedplate.
Control Speed Range Setting
The STT-10 Control is factory set for the 10 Series
low speed ratio wire drives. If using the Synergic 7F
wire drive, the speed range must be set up to match
this wire feed head by properly setting the switch (S1)
code on the control board inside the control box. See
OPERATION “Setting the DIP Switch” for setting
instructions.
10 Series Wire Drive Ratio Selection
The STT-10 Bench and Boom model packages come
with a 1" dia. gear only.
The K1563-1,-3 10 Series type Boom model wire drive
includes two external gear sizes; a 1"(25.4mm) dia.
gear and a 1-1/2"(38.1mm) dia. gear. The smaller
gear provides the desired low speed range ratio,
appropriate for the STT process per the SPECIFICATIONS in the front of this section.
The following procedure is for changing ratio of the 10
Series Boom wire drive (K1563-1,-3):
1) Pull open the Pressure Door.
5) Install the smaller, 1.00”(25.4mm) dia., gear onto output
shaft and secure with flat washer, lock washer, and
Phillips head screw which were previously removed.
6) Tighten the screw on lower right face of feedplate.
7) Install gear onto output shaft and secure with flat washer,
lock washer, and Phillips head screw which were previously removed.
8) Re-attach feedplate to wire feeder if removed in Step 2.
9 Feedplate will be rotated out-of-position due to the gear
change. To re-adjust angle of feedplate:
a) Loosen the clamping collar using a 3/16" Allen
wrench. The clamping collar screw is accessed
from the bottom of the feedplate. It is the screw
which is perpendicular to the feeding direction.
b) Rotate feedplate to the desired angle and tight-
en clamping collar screw.
10) Make sure to properly set the switch (S1) code on the
control board inside the control box for the new gear
size installed. See OPERATION “Setting the
Switch” for setting instructions.

To Mount a 50-60 Lb. (22.7-27.2 kg) Coil:
(Using K1504-1 Coil Reel) (For 50-60 lb Readi-
Reels a K438 Readi-Reel Adapter must be used).
The Spindle must be located in the UPPER mounting hole.
1) With the K1504-1 Coil Reel mounted on to the 2"
(51 mm) spindle (or with reel laying flat on the
floor) loosen the spinner nut and remove the reel
cover. (See Figure B.2).
2) Before cutting the tie wires, place the coil of electrode on the reel so it unwinds from the bottom as
the reel rotates.
3) Tighten the spinner nut against the reel cover as
much as possible by hand using the reel cover
spokes for leverage. DO NOT hammer on the
spinner nut arms.
4) Cut and remove only the tie wire holding the free
end of the coil. Hook the free end around the rim
of the reel cover and secure it by wrapping it
around. 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.
___________________________________________
5) Be sure the coil reel is engaged with the spindle
brake pin and the Release Bar on the Retaining
Collar “pops up” and that the collar retainers fully
engage the retaining groove on the spindle.
FEEDING ELECTRODE AND BRAKE
ADJUSTMENT
1) Turn the Reel or spool until the free end of the
electrode is accessible.
2) While tightly holding the electrode, cut off the bent
end and straighten the first 6" (150 mm). Cut off
the first 1" (25 mm). (If the electrode is not properly straightened, it may not feed or may jam causing
a "birdnest".)
3) Insert the free end through the incoming guide
tube.
4) Press the Cold Inch key or the Cold Feed Mode
gun trigger and push the electrode into the drive
roll.
WARNING
When feeding with the gun trigger, unless “COLD
FEED” trigger mode is selected, the electrode and
drive mechanism are always “HOT” to work and
ground and could remain “HOT” several seconds after
the gun trigger is released.
___________________________________________
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.

DRIVE ROLL PRESSURE SETTING
The STT-10 pressure is factory pre-set to about position “2" as shown on the pressure indicator on the
front of the feedplate door. This is an approximate
setting.
The optimum drive roll pressure varies with type of
wire, surface condition, lubrication, and hardness.
Too much pressure could cause “birdnesting”, but too
little pressure could cause wire feed slippage with
load and/or acceleration. The optimum drive roll setting can be determined as follows:
STT-10
Page 25

OPERATION
B-8
1) 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 drive 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, pull the gun cable forward about 6" (150
mm). There should be a slight waviness in the
exposed wire. If there is no waviness, the pressure is too low. Increase the pressure setting
turn, reconnect the gun, tighten locking clamp and
repeat the above steps.
PROCEDURE FOR SETTING ANGLE
OF FEEDPLATE
1) Loosen the clamping collar screw using a 3/16"
Allen wrench. The clamping collar screw is
accessed from the bottom of the feedplate. It is
the screw which is perpendicular to the feeding
direction.
2) Rotate feedplate to the desired angle and tighten
clamping collar screw.
GAS GUARD REGULATOR SETTING
4) Use Control Select and encoder knobs to set desired
Weld feed speed and current then Run-in speed to
optimize arc starting. (Set for each procedure if
using front panel, or optional dual procedure switch.)
(Refer to “Operation Keys” and “Display Control
Keys” in this section)
5) Adjust the wire feed acceleration if desired, for
each feeder and procedure. (Refer to “Acceleration
Selection” in this section)
6) Use Control Select and top Encoder knob to set
desired timers. (Refer to “Trigger Mode Selection”
in this section)
7) Feed the electrode through the gun and cable and
then cut the electrode within approximately 3/8”
(9.5 mm) of the end of the contact tip for solid wire
and within approximately 3/4” (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.
NOTE: Gas supply pressure must be regulated to a
maximum of 80 psi(5.5 bar).
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
l/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 an STT-II power source with the STT-10
Wire Feeder.
2) Properly connect the electrode and work leads for
the correct electrode polarity.
3) Use the Trigger Mode Selection key to set desired
trigger mode for each procedure. (Refer to “Trigger
Mode Selection” in this section)
____________________________________
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.
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.
13) If necessary to optimize arc starting, readjust wire
speed acceleration, (Refer to “Acceleration
Selection” in this section) and/or Run-In speed,
(Refer to “Display Control Keys” in this section).

OPERATION
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:
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 STT-10 wire drive 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.

display is showing acceleration setting, “1"
to “5" (See “Acceleration Selection” in this
section).
SECDisplayed on WFS display, indicates
Voltage display is showing a Timer setting

4) After the electrode has been removed, reconnect
the gun cable to the drive. Load a new reel of electrode per the instructions in “Wire Reel Loading” in
this section.
WIRE FEED OVERLOAD PROTECTION
The STT-10 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 gas
solenoid, and then displays “H30” on the WFS display
(with blank Voltage display). This indicates the wire
drive motor is overloaded and will remain shut down for
about 30 seconds before the unit will automatically
reset. The “H30” display decrements every second until
it reaches “H00”. At that time, the unit resets automatically and the previous displays 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 “Avoiding Wire Feeding Problems” in the MAINTENANCE section).
GROUNDING LEAD PROTECTOR
The frame of the STT-10 Control is grounded to the
frame of the power source by a lead in the control cable.
An overload protector prevents welding current from
damaging this lead if the electrode circuit touches the
wire feeder frame while the electrode is electrically hot.
If such a grounding lead fault occurs, the WFS display
will show “GLP,” (with blank Voltage display) and the
trigger circuit will be disabled. To reset the circuit,
release the trigger, make sure that the electrode is not
touching the wire feeder frame, and then either press
any key on the keypad or close the trigger. When the
GLP circuit is reset, the “GLP” display is removed and
the wire feeder is returned to normal operating mode.
GLPDisplayed on WFS display, indicates that
the Grounding Lead Protector circuit was
activated due to excessive current flow into
the wire feeder frame. When the GLP circuit is activated the wire feeder is disabled
(the trigger output to the power source is
opened up, the motor is stopped, and the
gas solenoid is turned off). To resume normal operation, release the trigger, make
sure that the electrode is not touching the
wire feeder frame, and then either press a
key on the keypad or close the trigger.

Safety Precautions
WARNING
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 and could remain energized several
seconds after the gun trigger is released.
• Turn OFF input power at welding power
source before installation or changing
drive roll and/or guide tubes.
• Welding power source must be connected
to system ground per the National
Electrical Code or any applicable local
codes.
• Only qualified personnel should
perform this installation.
Observe all additional Safety Guidelines detailed
throughout this manual.
Routine Maintenance
Wire feeding problems can be avoided by observing
the following gun handling and feeder set up procedures:
• Do not kink or pull cable around sharp corners.
• Keep the electrode cable as straight as possible
when welding or loading electrode through cable.
• Do not allow dolly wheels or trucks to run over
cables.
• Keep cable clean by following maintenance
instructions.
• Use only clean, rust-free electrode. The Lincoln
electrodes have proper surface lubrication.
• Replace contact tip when the arc starts to become
unstable or the contact tip end is fused or
deformed.
• Do not use excessive wire spindle brake settings.
• Use proper drive rolls, guide tubes and drive roll
pressure settings.
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.
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 have no teeth, but use two grooves so they
also can be reversed for additional life.
See “Procedure to Install Drive Roll and Guide Tubes”
in the INSTALLATION section for roll changing
instructions.
Wire Reel Mounting - Readi-Reels and
10 through 30lb (4.5-14kg) Spools
No routine maintenance required. Do not lubricate 2”
(51mm) spindle.
Periodic Maintenance
Wire Drive Motor and Gearbox
Every year inspect the gearbox and coat the gear
teeth with a moly-disulfide filled grease. Do not use
graphite grease.
Every six months check the motor brushes. Replace
them if they are less than 1/4” long.
Gun and Cable Maintenance
See appropriate Operatorʼs Manual.
Procedure for Removing Feedplate from
Wire Feeder
1) Loosen the clamping collar screw using a 3/16"
Allen wrench. The clamping collar screw is
accessed from the bottom of the feedplate. It is
the screw which is perpendicular to the feeding
direction.
2) Loosen the retaining screw, which is also
accessed from bottom of feeder, using a 3/16"
Allen wrench. Continue to loosen the screw until
the feedplate can be easily pulled off of the wire
feeder.
