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.
5.e. Also see item 1.b.
Mar ‘95
WELDMARK 135 PLUS
FOR ELECTRICALLY
powered equipment.
8.a. Turn off input power using the disconnect
switch at the fuse box before working on
the equipment.
8.b. Install equipment in accordance with the U.S. National
Electrical Code, all local codes and the manufacturer’s
recommendations.
8.c. Ground the equipment in accordance with the U.S. National
Electrical Code and the manufacturer’s recommendations.
CYLINDER may explode
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.
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 cir-
cuits. 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
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.
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 ray-
onnement 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 lev-
age, 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.
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 debranch-
er à l’interrupteur à la boite de fusibles.
4. Garder tous les couvercles et dispositifs de sûreté à leur
place.

connector is all the way in the metal connector
block to obtain proper gas flow. Rotate the connec-
tor so control leads are on the underside and tight-
en the Thumbscrew (8) in the connector block.
4. Connect the gun trigger control lead terminals to
the two insulated 1/4" (6,4 mm) tab connector
bushings located above the “Gun Trigger
Connection” decal in the wire feed section (4).
Either lead can go to either connector. Form the
leads so that they are as close as possible to the
inside panel.
If the gun trigger switch being used is other than
that supplied with the welder, the switch must be a
normally open, momentary switch. The terminals
of the switch must be insulated from the welding
circuit. Malfunction of the welder will result if this
switch shorts to the welding output circuit or is
common to any electrical circuit other than the
welder trigger circuit.

INSTALLATION
CODE REQUIREMENTS FOR INPUT
CONNECTIONS
This welding machine must be connected to
power source in accordance with applicable elec-
trical codes.
The United States National Electrical Code (Article
630-B, 1990 Edition) provides standards for amperage
handling capability of supply conductors based on
duty cycle of the welding source.
If there is any question about the installation meeting
applicable electrical code requirements, consult a
qualified electrician.
Requirements For Rated Output
A power cord with a 15 amp, 125 volt, three prong
plug (NEMA Type 5-15P) is factory installed on the
welder. Connect this plug to a mating grounded recep-
tacle which is connected to a 20 amp branch circuit
with a nominal voltage rating of 115 to 125 volts, 60
Hertz, AC only.
The rated output with this installation is 90 amps, 18
Volts, 20% duty cycle (2 minutes of every 10 minutes
used for welding).
Do not connect the welder to an input power sup-
ply with a rated voltage that is greater than 125
volts.
Do not remove the power cord ground prong.
Requirements For Maximum Output
In order to utilize the maximum output capability of the
machine, a branch circuit capable of 25 amps at 115
to 125 volts, 60 Hertz is required. This generally
applies when welding steel that is equal to or greater
than 12 gauge, 0.105” (2.5 mm) in thickness.

Refer to Figure B.1b.
5. Gun Trigger - Activates welding output, wire feed,
and gas solenoid operation. Releasing the trigger
deactivates welding and simultaneously activates
the “burnback” function so that the welding wire
does not stick in the weld puddle.
6. Optional K695-2 Spot/Stitch Controls (see ACCES-
SORIES section) - If present, replaces Blank Panel
Assembly located on the center panel inside the
case door:
Mode Switch - Selects between Spot, Stitch, or
Seam (normal welding) mode. Spot mode welds for
an adjustable length of time (set by Time Control;
see below) and then stops, whenever the gun trig-
ger is depressed and held. Stitch mode cycles
between welding and not welding for an adjustable
length of time (also set by Time Control) while the
gun trigger is depressed. In Seam mode the
machine will weld continuously while the gun trig-
ger is depressed. Releasing the gun trigger in any
of the three modes will interrupt welding immedi-
ately.
Time Control - In Spot mode, controls spot mode
ON time between approximately .25 and 4.0 sec-
onds. In Stitch mode, controls stitch mode ON time
and OFF time simultaneously between .25 and 4.0
seconds each. This control is deactivated while in
Seam mode.
WELDING OPERATIONS
SEQUENCE OF OPERATION
Wire Loading
Refer to Figure B.2 AND B3.
The machine power switch should be turned to the
OFF (“O”) position before working inside the wire feed
enclosure.
The machine is shipped from the factory ready to feed
4” (100 mm) diameter spools. A 4" (100 mm) diameter
spool is mounted directly on the 5/8" (16 mm) diame-
ter spindle that has a built-in adjustable friction brake
to prevent overrun of the spool and excess slack in
the wire. The wing nut at the end of the shaft is used
to adjust the tension on the wire spool (See B.3 on the
following page).
To use 8" (200 mm) diameter spools, the 2" (51 mm)
diameter M15445 spindle must be used. Remove the
spacer and wing nut at the end of the shaft. Insert
spindle as shown in figure B.2. Reattach spacer and
wing nut.
Note: When loading and removing the 8” Spools
make sure that the wing nut (inside the wire spool
spindle hub) is turned 90° from the wire spool spindle
locking tab. If the wing nut is positioned in line with the
locking tab, the tab cannot be depressed to load or
unload the wire spool.
Make certain the start end of the wire, which may pro-
trude through the side of the spool, does not contact
any metallic case parts.

Friction Brake Adjustment
With wire spool installed on the spindle shaft and the
wing nut loose, turn the spool by hand while slowly
tightening the wing nut until a light drag is felt. Tighten
the wing nut an additional 1/4 turn.
Note: When properly adjusted, the brake should pro-
vide only enough drag to prevent overrun of the spool
and excess slack in the wire. Too much drag may
result in wire feeding problems, and may cause pre-
mature wear of wire drive system components.
Wire Threading
Refer to Figure B.4
1. Release the Spring Loaded Pressure Arm (1)
rotate the Idle Roll Arm (2) away from the Wire
Feed Drive Roll (3). Ensure that the visible, sten-
ciled size on the drive roll matches the wire size
being used.
2. Carefully detach the end of the wire from the
spool. To prevent the spool from unwinding, do
not release the wire until after step 5.
3. Cut the bent portion of wire off and straighten the
first 4” (100 mm).
4. Thread the wire through the In-going guide tube
(4), over the drive roll (3), and into the out-going
guide tube (5).
5. Close the idle roll arm (2) and latch the spring
loaded pressure arm (1) in place (now you may
release the welding wire).
6. The idle roll pressure adjustment wing nut is factory
set to approximately five full turns from where the
wing nut first engages the threads of the pressure
arm (1). If feeding problems occur because the wire
is flattened excessively, turn the pressure adjust-
ment counter-clockwise to reduce distortion of the
wire. Slightly less pressure may be required when
using 0.023 – 0.025" (0,6 mm) wire. If the drive roll
slips while feeding wire, the pressure should be
increased until the wire feeds properly.
When inching the welding wire, the drive rolls, the
gun connector block and the gun contact tip are
always energized relative to work and ground and
remain energized several seconds after the gun
trigger is released.
7. Refer to Figure B.5. Remove gas nozzle and con-
tact tip from end of gun.
8. Turn the WELDMARK 135 PLUS ON (“I”).
9. Straighten the gun cable assembly.
10. Depress the gun trigger switch and feed welding
wire through the gun and cable. (Point gun away
from yourself and others while feeding wire.)
Release gun trigger after wire appears at end of
gun.
Note: If the wire will not feed smoothly, or if the wire
feed motor shuts off unexpectedly, see the
"FEEDING PROBLEMS" section of the "TROU-
BLESHOOTING GUIDE" in this manual.
11. Replace contact tip and gas nozzle.
12. Refer to Figure B-6. Cut the wire off 1/4”– 3/8”
(6 – 10 mm) from the end of the tip. The WELD-
MARK 135 PLUS is now ready to weld.

OPERATION
Shielding Gas
When using the GMAW process, a cylinder of shield-
ing gas, must be obtained. Refer to the ACCES-
SORIES section for more information about selecting
gas cylinders for use with the WELDMARK 135 PLUS.
1. For CO
2
, open the cylinder very slowly. For argon-
mixed gas, open cylinder valve slowly a fraction of
a turn. When the cylinder pressure gauge pointer
stops moving, open the valve fully.
2. If using a regulator with an adjustable flow meter,
close the gun trigger and adjust the flow to give 15
– 20 cubic ft per hour (CFH) (7 – 10 I/min) [use 20
-– 25 CFH (10 – 12 I/min) when welding out of
position or in a drafty location for CO
2
]. For argon
mixed gas, trigger to release gas pressure, and
turn off the adjust the flow to give 25 – 30 CFH
(12 – 14 I/min).
3. Keep the cylinder valve closed, except when using
the welder. When finished welding:
a) Close the cylinder valve to stop gas flow.
b) Depress the gun trigger briefly to release the
pressure in the gas hose.
c) Turn off the welder.
Making A Weld
1. See Recommended Processes And Equipment
section for selection of welding wire and shielding
gas and for range of metal thicknesses that can be
welded.
2. See the Application Chart on the inside of wire
feed section door for information on setting the
SP-135 PLUS controls.
3. Set the Voltage (“V”) and Wire Speed (“olo’”) con-
trols to the settings suggested for the welding wire
and base metal thickness being used.
FIGURE B.6FIGURE B.5

4. Check that the polarity is correct for the welding
wire being used and that the gas supply, if
required, is turned on.
5. When using Innershield electrode, remove the gas
nozzle and install the gasless nozzle. This will
improve visibility of the arc and protect the gas dif-
fuser from weld spatter. Refer to the MAINTE-
NANCE section for details on nozzle replacement.
6. Refer to Figure B.7. Connect work clamp to metal
to be welded. Work clamp must make good elec-
trical contact to the workpiece. The workpiece
must also be grounded as stated in “Arc Welding
Safety Precautions” in the beginning of this manu-
al.
7. Position gun over joint. End of wire may be lightly
touching the work.
8. Lower welding helmet, close gun trigger, and
begin welding. Hold the gun so the contact tip to
work distance is about 3/8 inch (10 mm).

OPERATION
9. To stop welding, release the gun trigger and then
pull the gun away from the work after the arc goes
out.
10. When no more welding is to be done, close valve
on gas cylinder (if used), momentarily operate gun
trigger to release gas pressure, and turn off the
welder.
Cleaning Tip And Nozzle
Clean the contact tip and nozzle to avoid arc bridging
between the nozzle and contact tip which can result in
a shorted nozzle, poor welds and an overheated gun.
Hint: Anti-stick spray or gel, available from a welding
supply distributor, may reduce buildup and aid in spat-
ter removal.
PROCESS GUIDELINES
The WELDMARK 135 PLUS can be used for welding
mild steel using the GMAW, single pass, process
which requires a supply of shielding gas or it can be
used for the self shielded, Innershield
®
process
(FCAW).
The recommended gases and electrodes for GMAW
are welding grade CO
2
gas or an argon-CO
2
blended
gas (75 to 80% argon and 25 to 20% CO
2
) and .025"
(0.6 mm) diameter Lincoln L-56 mild-steel welding
wire, supplied on 12-1/2 lb (5.7 kg) spools.
The recommended electrode for the self-shielded
process is 0.035” (0,9 mm) diameter Lincoln
Innershield NR-211-MP on 10 Ib (4,5 kg) spools. This
electrode can be used for all position welding of 20
gauge through 5/16” (1,0 – 8,0 mm) thick steel [multi-
ple passes are required for 1/4” and 5/16” (6,0 and 8,0
mm)].
The WELDMARK 135 PLUS is suitable for .035"
Aluminum wire and .030" stainless wire. Refer to
Table B.1 for Recommended Procedure Settings.
Aluminum wire requires K663-1 Aluminum Welding kit.
See ACCESSORIES section.
It is important when changing between welding
with steel wire and aluminum to exchange feeding
components due to the lubricant applied to steel
wire. Failure to do so may result in contaminated
welds when welding aluminum.

CHANGING MACHINE OVER TO
FEED OTHER WIRE SIZES
The WELDMARK135 PLUS is shipped from the facto-
ry ready to feed 0.023-0.025” (0,6 mm) diameter wire.
To operate the welder with other sizes of wire, it is
necessary to change the contact tip and change the
drive roll over to other sizes. Refer to Changing the
Contact Tip and Changing the Drive Roll, in the MAIN-
TENANCE section, for specific information on these
procedures.
WELDING WITH FCAW (Innershield)
Welding with Innershield requires an Innershield
Welding Kit. A gasless nozzle is provided in the
Innershield Welding Kit. When using Innershield elec-
trode, installing the gasless nozzle will improve visibili-
ty of the arc and protect the gas diffuser from weld
spatter. Additionally included is a gun cable liner to
permit proper feeding of .035” (0,9 mm) Innershield
wire. Refer to the ACCESSORIES section for details
on obtaining this kit.

WARNING
Use of the GMAW process with the WELDMARK
135 PLUS on thicker materials than recommended
may result in poor welds. The welds may “look”
good, but may just be “sitting” on top of the plate.
This is called “cold casting” and will result in weld
failure.

OPERATION
OVERLOAD PROTECTION
Output Overload
The WELDMARK 135 PLUS is equipped with a circuit
breaker which protects the machine from potential
damage from excessive output current. The circuit
breaker button will extend out when tripped. The cir-
cuit breaker must be manually reset.
Thermal Protection
The WELDMARK 135 PLUS duty cycle is exceeded a
thermostat will shut off the output until the machine
cools to a normal operating temperature. This is an
automatic function and is self resetting.
Wire Feed Overload Protection
If the WELDMARK 135 PLUS has an automatic elec-
tronic protection circuit to protect the wire feed motor.
If excessive motor overload occurs (due to excessive
feeding force, jammed drive rolls, or shorted motor
leads) the circuit will shut down the wire feed motor
and the welding power output.
The wire feed shut-down circuit will reset automatically
when the gun trigger is released. However shut-down
will reoccur if the overload situation is not corrected.
