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.

CALIFORNIA PROPOSITION 65 WARNINGS

Diesel engine exhaust and some of its constituents

are known to the State of California to cause can-

cer, birth defects, and other reproductive harm.

SAFETY

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

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

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.

6.h. Also see item 1.c.

SAFETY

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.

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.

GENERAL DESCRIPTION

The WELDMARK 135 PLUS is a complete semiauto-

matic constant voltage DC arc welding machine.

Included is a solid state controlled, single phase con-

stant voltage transformer/ rectifier power source and a

wire feeder for feeding solid steel electrode and cored

electrode.

The WELDMARK 135 PLUS is ideally suited for indi-

viduals having access to 115 volt AC input power, and

wanting the ease of use, quality and dependability of

both gas metal arc welding or GMAW (also known as

MIG welding) and the Innershield electrode process

(self shielded flux cored or FCAW). The WELD-

MARK135 PLUS is a rugged and reliable machine that

has been designed for dependable service and long

life.

RECOMMENDED PROCESSES

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

amps, 18 volts, at 20% duty cycle on a ten minute

basis. It is capable of higher duty cycles at lower out-

put currents.

LIMITATIONS

Arc Gouging cannot be performed with the WELD-

MARK 135 PLUS and it is not recommended for pipe

thawing.

CONTROLS AND SETTINGS

Refer to Figures B.1a & B.1b.

1. Power ON/OFF Switch —

When the power is on the

fan motor will run and air will

be exhausted out the louvers

in the front of the machine.

The welding output and wire

feeder remain off until the

gun trigger is pressed.

2. Voltage Control — A contin-

uous control that gives full

range adjustment of power

source output voltage.

Voltage can be adjusted

while welding.

3. Wire Speed Control —

Controls the wire feed speed

from 50 – 400 in /min (1.3 –

10 m/min). The control can

be preset on the dial to the

setting specified on the

welder Application Chart

located on the inside of the

wire feed section door. Wire

speed is not affected when

4. Circuit Breaker – Protects machine from damage if

maximum output is exceeded. Button will extend

out when tripped (Manual reset).

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.

OPERATION

FIGURE B.3

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

, 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

]. 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

Gun Handle

Gas Diffuser

Gas Nozzle

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

gas or an argon-CO

blended

gas (75 to 80% argon and 25 to 20% CO

) 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.

CAUTION

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.
