SECTION 2:

SAFETY PRECAUTIONS

WARNING

SERIOUS INJURY OR DEATH may result if welding and cutting equipment is not

properly installed, used, and maintained. Misuse of this equipment and other
unsafe practices can be hazardous. The operator, supervisor, and helper must read
and understand the following safety warnings and instructions before installing
or using any welding or cutting equipment, and be aware of the dangers of the
welding or cutting process. Training and proper supervision are important for a
safe work place. Keep these instructions for future use. Additional recommended
safety and operating information is referenced in each section.

WARNING

This product contains chemicals, including lead, or otherwise produces
chemicals known to the State of California to cause cancer, birth defects and
other reproductive harm. Wash hands after handling.
(California Health & Safety Code § 25249.5 et seq.)

ELECTRIC SHOCK CAN CAUSE INJURY OR DEATH

Install and maintain equipment in accordance with the National Electrical Code
(NFPA 70) and local codes. Do not service or repair equipment with power on.
Do not operate equipment with protective insulators or covers removed. Service
or repair to equipment must be done by qualified and/or trained
personnel only.

Do not contact electrically live parts. Always wear dry welding gloves that are in good condition.
Aluminized, protective clothing can become part of the electrical path. Keep oxygen cylinders,
chains, wires, ropes, cranes, and hoists away from any part of the electrical path. All ground
connections must be checked periodically to determine if they are mechanically strong, and
electrically adequate for the required current. When engaged in AC welding/cutting under wet
conditions or where perspiration is a factor, the use of automatic controls for reducing the no
load voltage is recommended to reduce shock hazards. Accidental contact must be prevented
when using open circuit voltage exceeding 80 volts AC, or 100 volts DC by adequate insulation
or other means. When welding is to be suspended for any length of time, such as during lunch
or overnight, all electrode holders and electrodes should be removed from the electrode holder
and the power supply should be turned off to prevent accidental contact. Keep MIG Guns,
electrode holders, Tig torches, Plasma torches, and electrodes away from moisture and water.

See safety and operating references 1, 2, and 8.

Safety Precautions

2-2

89200000

Safety and Operating inStructiOnS

SMOKE, FUMES, AND GASES CAN BE DANGEROUS TO YOUR HEALTH

Ventilation must be adequate to remove smoke, fumes, and gases during operation
to protect operators and others in the area. Vapors of chlorinated solvents can
form the toxic gas “Phosgene” when exposed to ultraviolet radiation from an
electric arc. All solvents, degreasers, and potential sources of these vapors must
be removed from the operating area. Use air-supplied respirators if ventilation

is not adequate to remove all fumes and gases. Oxygen supports, and vigorously accelerates fire
and should never be used for ventilation.

See safety and operating references 1, 2, 3, and 4.
ARC RAYS, HOT SLAG, AND SPARKS CAN INJURE EYES AND BURN SKIN

Welding and cutting processes produce extreme localized heat and strong
ultraviolet rays. Never attempt to weld/cut without a federally compliant welding
helmet with the proper lens. A number 12 to 14 shade filter lens provides the
best protection against arc radiation. When in a confined area, prevent the

reflected arc rays from entering around the helmet. Approved shielding curtains
and appropriate goggles should be used to provide protection to others in the surrounding area.
Skin should be protected from arc rays, heat, and molten metal. Always wear protective gloves
and clothing. All pockets should be closed and cuffs sewn shut. Leather aprons, sleeves, leggings,
etc. should be worn for out-of-position welding and cutting, or for heavy operations using large
electrodes. Hightop work shoes provide adequate protection from foot burns. For added protection,
use leather spats. Flammable hair preparations should not be used when welding/cutting. Wear
ear plugs to protect ears from sparks. Where work permits, the operator should be enclosed in
an individual booth painted with a low reflective material such as zinc oxide.

See safety and operating references 1, 2, and 3.
WELDING SPARKS CAN CAUSE FIRES AND EXPLOSIONS

Combustibles reached by the arc, flame, flying sparks, hot slag, and heated
materials can cause fire and explosions. Remove combustibles from the work
area and/or provide a fire watch. Avoid oily or greasy clothing as a spark may
ignite them. Have a fire extinguisher nearby, and know how to use it. If welding/
cutting is to be done on a metal wall, partition, ceiling, or roof, precautions must

be taken to prevent ignition of nearby combustibles on the other side. Do not
weld/cut containers that have held combustibles. All hollow spaces, cavities, and containers
should be vented prior to welding/cutting to permit the escape of air or gases. Purging with inert
gas is recommended. Never use oxygen in a welding torch. Use only inert gases or inert gas
mixes as required by the process. Use of combustible compressed gases can cause explosions
resulting in personal injury or death. Arcing against any compressed gas cylinder can cause
cylinder damage or explosion. See safety and operating references 1, 2, 5, 7, and 8.

NOISE CAN DAMAGE HEARING

Noise from the air carbon-arc process can damage your hearing. Wear protective
hearing devices to ensure protection when noise levels exceed OHSA standards.
Adequate hearing protection devices must be worn by operators and surrounding
personnel to ensure personal protection against noise. See safety and operating

references 1, 2, and 6.

de reproduction. Il faut se laver les mains après toute manipulation.
(Code de Californie de la sécurité et santé, paragraphe 25249.5 et suivants)

UN CHOC ÉLECTRIQUE PEUT CAUSER DES BLESSURES OU LA MORT

L’installation et l’entretien de l’équipement doivent être conformes au Code national
de l’électricité NFPA 70 et aux codes locaux. N’effectuez pas l’entretien ou la
réparation d’équipement en marche. N’opérez pas l’équipement sans isolateurs ou
caches de protection. L’entretien ou la réparation de l’équipement doivent être
effectués uniquement par un technicien qualifié ou par du personnel formé.

Ne touchez pas aux pièces électriques chargées. Portez toujours des gants de soudage au sec
et en bon état. Les vêtements de protection aluminisés peuvent devenir une partie du chemin
électrique. Éloignez les bouteilles d’oxygène, les chaînes, les câbles métalliques, les appareils
de levage, les treuils et les élévateurs de toute partie du circuit électrique. Toutes les liaisons de
terre doivent être vérifiées périodiquement pour déterminer si elles sont solides et appropriées au
courant demandé. En cas de soudage ou de découpage en courant alternatif dans des conditions
d’humidité ou de chaleur où l’opérateur risque de transpirer, il est recommandé d’utiliser des
contrôles automatiques pour réduire la tension à vide et ainsi diminuer les risques de choc
électrique. Lorsque le procédé de soudage et de découpage exige des valeurs de tension en
circuit ouvert dans des machines à courant alternatif supérieur à 80 volts ou dans des machines
à courant continu supérieur à 100 volts, il faut prendre des mesures pour empêcher un contact
accidentel en prévoyant une isolation adéquate ou d autres moyens. Lorsqu’il faut interrompre
les activités de soudage pendant un certain temps, à l’heure du repas ou la nuit, par exemple, il
faut enlever toutes les électrodes du porte-électrode et mettre hors tension l’alimentation pour
éviter tout contact accidentel. Gardez les pistolets MIG, les porte-électrodes, les torches TIG, les
torches à plasma et les électrodes loin de l’humidité et de l’eau. Voir les références en matière

de sécurité et d’utilisation n° 1, 2 et 8.

Safety and Operating inStructiOnS

LA FUMÉE, LES ÉMANATIONS ET LES GAZ PEUVENT ÊTRE DANGEREUX POUR VOTRE SANTÉ

La ventilation doit être suffisante pour enlever la fumée, les émanations et les
gaz pendant le fonctionnement de la torche afin protéger les opérateurs et les
autres personnes présentes dans la zone. Les vapeurs de solvants chlorés
peuvent former un gaz toxique appelé « Phosgène » si elles sont exposées au

rayonnement ultraviolet d un arc électrique. Il faut enlever de la zone de travail
tous les solvants, décapants et sources potentielles de ces vapeurs. Servez-vous d’appareils
respiratoires à adduction d’air si la ventilation n’est pas suffisante pour enlever toutes les
émanations et gaz. L’oxygène alimente les incendies et en accélère la propagation il ne faut

jamais l’utiliser à des fins de ventilation. Voir les références en matière de sécurité et
d’utilisation n° 1, 2, 3 et 4.

L LES RAYONS DE L’ARC, LES SCORIES ET LES ÉTINCELLES CHAUDS PEUVENT BLESSER
LES YEUX ET BRÛLER LA PEAU

Les procédés de soudage et de découpage produisent une chaleur extrême
localisée et de puissants rayons ultraviolets. N’essayez jamais de souder ou de
couper sans casque soudage conforme aux normes du gouvernement fédéral et
muni d’une lentille appropriée. Des lentilles à filtre de numéro 12 à 14 fournissent

la meilleure protection contre le rayonnement de l’arc. Dans un endroit confiné,
il faut éviter que les rayons reflétés de l’arc n’entrent autour du casque. Il faut utiliser des rideaux
de protection approuvés et des lunettes de protection appropriées pour protéger les autres personnes
se trouvant aux abords. Il faut aussi protéger la peau nue des rayons de l’arc, de la chaleur et du
métal fondu. Portez toujours des gants et des vêtements de protection. Toutes les poches doivent
être fermées et les manchettes, cousues. Il faut porter un tablier, des manches, des guêtres, etc.
en cuir pour effectuer de soudage ou de découpage et dans le cas des activités intensives nécessitant
de grandes électrodes. Les chaussures de sécurité montantes fournissent une protection suffisante
contre les brûlures aux pieds. Pour obtenir une plus grande protection, portez des guêtres en cuir.
Il ne faut pas utiliser de produits capillaires inflammables avant d’effectuer des activités de soudage
ou de découpage. Portez des bouchons d’oreilles pour vous protéger les oreilles des étincelles.
Lorsqu’il est possible de le faire dans la zone de travail, l’opérateur doit s’isoler dans une cabine
individuelle recouverte d’un revêtement à faible réflectivité, comme l’oxyde de zinc. Voir les

références en matière de sécurité et d’utilisation n° 1, 2 et 3.
LES ÉTINCELLES DE SOUDAGE PEUVENT CAUSER DES INCENDIES ET DES EXPLOSIONS

Les combustibles atteints par l’arc, les flammes, les vols d’étincelles, les scories
chaudes et les matériaux chauffés peuvent causer des incendies et des explosions.
Enlevez les combustibles de la zone de travail ou mettez en place du personnel
de surveillance. Évitez les vêtements huileux ou graisseux, car une étincelle peut
y mettre le feu. Ayez un extincteur à proximité et sachez comment l’utiliser. Si

l’activité de soudage ou de découpage doit être fait contre un mur, une cloison,
un plafond ou un toit, il faut prendre des précautions pour d’enflammer des combustibles qui se
trouveraient à proximité, de l’autre côté. Ne soudez pas et ne coupez pas de conteneurs ayant
contenu des combustibles. Il faut aérer tous les espaces creux, les cavités et les conteneurs avant
de les soumettre au soudage ou au découpage afin d’évacuer tout l’air ou le gaz qui peut s’y
trouver. Il est recommandé d’effectuer une purge avec du gaz inerte. N’utilisez jamais d’oxygène
dans une tête de soudage. N’utilisez que des gaz inertes ou des mélanges de gaz inertes,
conformément aux exigences du procédé. L’utilisation de gaz combustibles comprimés peut
causer des explosions entraînant des blessures ou la mort. Le fait d’utiliser l’arc sur une bouteille
de gaz comprimé peut endommager la bouteille ou causer une explosion. Voir les références

EL HUMO, LOS VAPORES Y LOS GASES PUEDEN SER PELIGROSOS PARA LA SALUD

La ventilación debe ser adecuada para que salga el humo, los vapores y los
gases durante la operación para proteger a los operadores y al resto del personal
en el área. Los vapores de solventes clorados pueden formar el gas tóxico
“Fosgeno” cuando quedan expuestos a los rayos ultravioletas producidos por

un arco eléctrico. Todos los solventes, desengrasantes y fuentes potenciales de
esos vapores deben ser retirados del área de trabajo. Utilice respiradores con tanque de aire si
la ventilación no resulta adecuada para eliminar todos los humos y gases. El oxígeno sostiene y
acelera vigorosamente el fuego, por lo que nunca debe ser utilizado para ventilación. Consulte

las referencias de seguridad y uso 1, 2, 3 y 4.

LOS RAYOS DEL ARCO, LA ESCORIA CALIENTE Y LAS CHISPAS PUEDEN LASTIMAR LOS OJOS
Y QUEMAR LA PIEL

Los procesos de soldadura y corte producen calor extremadamente localizado
y fuertes rayos ultravioletas. Nunca intente soldar o cortar sin una máscara de
soldadura con lentes adecuados y que cumpla con las exigencias federales. Los
lentes con filtro número 12 a 14 ofrecen la mejor protección contra la radiación

del arco. Cuando trabaje en un área confinada, evite que los rayos reflejados del
arco entren alrededor de la máscara. Se deben usar cortinas de protección y gafas apropiadas
para proteger al personal presente en áreas cercanas. La piel también debe ser protegida de los
rayos del arco, del calor y del metal derretido. Siempre se deberán utilizar guantes y vestimenta
de protección. Todos los bolsillos deben estar cerrados y los dobladillos cosidos. Se deben usar
delantales de cuero, mangas, pantalones, etc., para la soldadura y el corte fuera de posición o
para operaciones pesadas con electrodos grandes. Las botas de trabajo de caña alta ofrecen
protección adecuada contra las quemaduras de los pies. Use protectores de cuero para brazos
y piernas para contar con protección adicional. No se deben usar productos inflamables para el
cabello cuando se suelde o corte. Usar orejeras para proteger las orejas de las chispas. Cuando
el área de trabajo lo permita, el operador debe trabajar dentro de una cabina individual pintada
con una terminación de baja reflexión, como por ejemplo: óxido de zinc. Consulte las referencias

de seguridad y uso 1, 2 y 3.

LAS CHISPAS DE SOLDADURA PUEDEN CAUSAR INCENDIO Y EXPLOSIONES

Los combustibles alcanzados por el arco, por llamas, chispas, escorias o materiales
calientes pueden ser las causas de incendios y explosiones. Retire los combustibles
del área de trabajo u organice una guardia contra incendios. Evite que las ropas
estén sucias con aceite o grasa, ya que una chispa puede encenderlas. Tenga un
extintor de incendios cerca y sepa como usarlo. Si se está soldando o cortando

en una pared, un divisorio, un cielorraso o un techo metálico, se deben tomar
precauciones para evitar la ignición de combustibles que puedan estar del otro lado. No suelde
ni corte recipientes que hayan contenido combustibles. Todos los espacios vacíos, cavidades y
recipientes deben ventilarse antes de soldar o cortar para permitir la salida de aire o gases. Se
recomienda purgarlos con gas inerte. Nunca use oxígeno en un soplete de soldar. Use solamente
gases inertes o mezclas de gases inertes conforme a lo exigido por el proceso. El uso de gases
comprimidos combustibles puede provocar explosiones y causar daños personales o la muerte.
La radiación del arco contra cualquier tubo de gas comprimido puede causarle daños al tubo o
su explosión. Consulte las referencias de seguridad y uso 1, 2, 5, 7 y 8.

Safety and Operating inStructiOnS

3. After inserting a wire inlet guide or
conduit from the MIG Gun, tighten the
brass nut and O-ring seal inside feeder.
If this nut is not tightened it may cause
gas flow to escape, resulting in decreased
gas flow. When removing the inlet guide
or conduit, loosen this nut.

NOTE

DO NOT OVER-TIGHTEN. Ensure that the conduit/liner does not touch or rub

against drive rolls.

4. Adjust the drive roll pressure on the feeder to a minimum. If needed, drive roll pressure
may be increased in order to facilitate proper feedability. Do not tighten drive roll pressure
too much as it could deform the wire.

NOTE

The tension adjusters on both drive rolls should be set to the minimum setting
when using 3/64" (1,2mm) aluminum. For 1/16" (1,6mm) aluminum, the user
may need to tighten the rolls one or two turns of the adjusting screw.

5. Tighten the wire spool drag to finger tip tight. The spool, when pushed 1/4 turn, should
freely spin one complete rotation.

6. Adjust voltage and wire speed as recommended by the wire manufacturer. (Refer to
table in Section 6.01). Gun is now ready for operation.

NOTE

Do not weld with the gun if the cable is coiled in circles less than 3 ft. (91cm) in
diameter because this will cause wire feed problems.

NOTE

Wipe off drive rolls with a Scotch Pad between each spool of wire. Lay pad against
roller and push the inch switch button in the feeder cabinet to turn the rollers.

SETTINGS AND CONTROLS (SMART GUN)

5.01 SETTINGS AND CONTROLS

PulseMaster Smart Guns include integrated digital controls in the gun handle. These controls
allow the user to make adjustments to either welding current or arc length via the MIG gun
handle. The digital display provides the user with a visual confi rmation of the changes as
they are made.

Digital Display

Control Up + : Allows operator to make upward

(increase) adjustments.

Control Down - : Allows operator to make downward
(decrease) adjustments.

Select: Allows operator to switch between welding current,
metal thickness, and wire speed adjustment mode
to arc length adjustment mode.

NOTE

When changing between Tiptronic programs on the gun controls: pressing the
select button will make the number on the left (set) start flashing and enable
the gun to switch between sets of programs by pressing the up or down button
while the screen is blinking. If you press just the up or down buttons, the gun
will scroll between programs in that set, but will not go through other sets.

Example: 3 - 4 (3 is the set, 4 is the program).

5.02 ADJUSTMENT OPTIONS

The SELECT button allows the operator to navigate between the following settings on the
power supply:

NOTE

The operator will need to adjust the settings manually on the welder to change from
welding current to metal thickness or to wire speed. The SELECT button allows the operator
to change from "length of arc mode" to the mode set manually on the welder.

• Welding current (amperage), metal thickness, or wire speed mode.

• Arc length adjustment mode

The fi rst setting to display will be the last setting used on the power supply.

SECTION 6:

MANUAL GMAW WELDING

6.01 TYPES OF WELD TRANSFER MODES

A. Short-Circuiting

A commonly used GMAW transfer mode is known as short-circuiting or short-arc. Typically, a
carbon dioxide based shielding gas is used, the electrode wire is small, and the current is low.
As a result of the lower current, the heat input for the short-arc variation is reduced, making it
possible to weld thinner materials while decreasing the amount of distortion and residual stress
in the weld area. Molten droplets form on the tip of the electrode bridge the gap between the
electrode and the weld pool as a result of the lower welding current. This causes a short circuit
and extinguishes the arc, but it is quickly reignited after the surface tension of the weld pool
pulls the molten metal bead off the electrode tip. Setting the weld process parameters (volts,
amps and wire feed rate) within a relatively narrow band is critical to maintaining a stable arc:
generally between 100 to 200 amps at 17 to 22 volts for most applications.

NOTE

The transition from the short circuit to spray arc depends on the amperage,
voltage, and the gas mixture.

B. Globular

GMAW with globular metal transfer is often considered the most undesirable of the four major
GMAW variations, because of its tendency to produce high heat, a poor weld surface, and spatter.
The method was originally developed as a cost efficient way to weld steel using GMAW. This
variation uses carbon dioxide, a less expensive shielding gas than argon. As the weld is made,
a ball of molten metal from the electrode tends to build up on the end of the electrode, often in
irregular shapes with a larger diameter than the electrode itself. When the droplet finally detaches
either by gravity or short circuiting, it falls to the work piece, leaving an uneven surface and
often causing spatter. As a result of the large molten droplet, the process is generally limited
to flat and horizontal welding positions. The high amount of heat generated also is a downside,
because it forces the welder to use a larger electrode wire, increases the size of the weld pool,
and causes greater residual stresses and distortion in the weld area.

C. Spray

Spray transfer GMAW is well-suited to weld aluminum and stainless steel while employing
higher percentages of an inert shielding gas such as argon. In this GMAW process, the weld
electrode metal is rapidly passed along the stable electric arc from the electrode to the work
piece, essentially eliminating spatter and resulting in a high-quality weld finish. As the current
and voltage increases beyond the range of short circuit transfer the weld electrode metal
transfer transitions from larger globules through small droplets to a vaporized stream. Since
this vaporized spray transfer variation of the GMAW weld process requires higher voltage and
current than short circuit transfer, and as a result of the higher heat input and larger weld pool
area (for a given weld electrode diameter), it is generally used only on work pieces of thicknesses
above about 6.4 mm (0.25 in). Also, because of the large weld pool, it is often limited to flat
and horizontal welding positions and sometimes also used for vertical-down welds.

D. Pulsed-Spray

A more recently developed method, the pulse-spray metal transfer mode is based on the
principles of spray transfer but uses a pulsing current to melt the filler wire and allow one small
molten droplet to detach with each pulse. The pulses allow the average current to be lower,

89200000

6-17

Manual GMAW Welding

Safety and Operating inStructiOnS

decreasing the overall heat input and thereby decreasing the size of the weld pool and heat­affected zone while making it possible to weld thin work pieces. The pulse provides a stable
arc and no spatter, since no short-circuiting takes place. This also makes the process suitable
for nearly all metals, and a larger electrode wire can be used as well. The smaller weld pool
gives the variation greater versatility, making it possible to weld in all positions. The process
also requires that the shielding gas be primarily argon with a low carbon dioxide concentration.
Additionally, it requires a special power source capable of providing pulse currents.

6.02 HOLDING AND MANIPULATING THE TORCH

NOTE

GMAW can be welded in all positions: horizontal, vertical-down, vertical-up,
overhead and in horizontal-vertical position.

When horizontal welding, hold the torch vertical to the workpiece (neutral torch position) or up to 30°,
“pushing" the torch. For best depth of penetration and shielding gas coverage, hold the torch in the
neutral position. Please note that if the torch is tilted too far, it is possible that air will be sucked into
the shielded gas and may result in porosity. For vertical or overhead welding, a slight pushing motion
is required. For vertical-down welding, mostly used for thin materials, hold the torch at the neutral
or slightly “dragging" position. Some experience is required since the welding pool could run ahead
of the arc and cause weld defects. Thicker material presents a danger of possible lacks of fusion
because the welding pool is very liquid from high voltage and quick travel speed.

Welding direction

pushing the weld

Welding direction
dragging the weld

Avoid extreme side-to-side movements to avoid the weld pool damming up in front of the arc. If the
welding pool flows ahead of the welding arc, lacks of fusion might occur. Use a side-to-side motion at
a necessary width to reach both sides of the joint. If the joint is too wide, weld two parallel weld beads.
When performing vertical-up welding, the side-to-side motion follows the shape of an open triangle.

Safety and Operating inStructiOnS

A. Length of the arc

Welding with a longer arc reduces the penetration and the welding bead is wide and flat with increased
spattering. The welding material is transferred with slightly larger droplets than welding with a shorter
arc. A longer arc is useful for welding a fillet weld to form a flat or concave seam. Welding with a
shorter arc (at the same amperage) increases the penetration, and the welding bead is narrow and
high with reduced spattering. The welding material is transferred with smaller droplets.

Long Arc Short Arc

B. Length of the wire electrode

The distance between the torch and the workpiece should be 10-12 times the diameter of the wire.
Altering the distance of the torch will influence the electrode stick out.

A longer electrode stick out reduces the amperage and the penetration.
A shorter electrode stick out increases the amperage if the wire feed speed remains the same.

8.02 CONDUIT REMOVAL

NOTE

Replace liner if it is kinked, or if the hole is dirty, or worn. Make sure the end of the
liner is smooth.

1. Lay the MIG Gun out on a table or on the floor in a straight line. Make sure the gun is
fully extended and all twists in the cable are removed.

2. Remove the nozzle and loosen the conduit set screw in the gas diffuser. Then loosen
the conduit set screw in the rear connector plug. On Euro-Kwik® connections, remove
the conduit retaining cap.

3. Remove the diffuser and contact tip.

4. Grip the conduit stop and remove the conduit with a twisting motion.

8.03 TEFLON LINER OPTIONS

1. Uncoil conduit and lay on a flat surface, trying not to kink the material. A kink in the
conduit will cause interrupted feed and unsatisfactory performance.

2. The Teflon conduit is supplied with a brass conduit cap on the diffuser end to prevent
the Teflon from collapsing under the pressure of the set screw. The liner may also be
used with the optional ‘jump liner’ in place of the brass conduit cap, or with neither. The
features of each are listed below.

Teflon Liner Installation: The conduit cap is used to secure the Teflon liner in the gas

diffuser with the set screw. Without the conduit cap it is extremely important not to
overtighten the set screw in the gas diffuser due to the fact that it will collapse and affect
wire feed. This option provides extremely smooth feed and should be used in aluminum
applications up to 300 amps.

Jump Liner Installation: The jump liner is constructed from a conductive bronze wire.

The jump liner offers higher wear resistance in the conductor tube area of the MIG gun.
Particular alloys of wire such as stainless steel are very abrasive and using the jump liner
will prolong the life of the liner. The jump liner also aids with inconsistencies in the arc
sometimes caused by straightened wire and oversized contact tips. The jump liner can
also be utilized in high heat applications to protect the Teflon from the higher temperatures
closer to the arc.

Bare Teflon Liner Installation: With the bare Teflon, the liner will need to be held very

lightly by the set screw at the front of the gun.

NOTE

For best results, bare teflon is not recommended.

8.04 STEP-BY-STEP TEFLON LINER INSTALLATION

When installing a standard Teflon liner with the brass conduit cap, take the following steps to
install the pieces into the gun:

1. Remove the gas nozzle, loosen the set screw in the gas diffuser and the rear feeder
power plug and remove the old liner from the gun.

2. Gently feed the new liner into the gun with short strokes, taking care not to kink the
liner. If the liner hangs up inside the gun, twist in a clockwise direction while gently
pushing.

3" - 4"

(7cm-10cm)

a. Correct Liner Feed Method:

Use short strokes

3. Feed the end of the liner through the
conductor tube until it cannot go any further
and secure with the diffuser set screw. If
unsure whether the brass conduit cap is
seated properly in the diffuser, remove the
set screw and check to see if the brass
conduit cap is visible inside the set screw
hole.

4. To secure the back end of the liner, completely push the conduit stop into the rear feeder
power plug and trim liner flush with the back of the conduit stop.

b. Incorrect Liner Feed Method:

Handling liner too far from plug

8" - 10"

(20cm-25cm)

5. Firmly press end of conduit stop against
a solid surface and lock in place with set
screw.

8.05 STEP-BY-STEP JUMP LINER INSTALLATION

When installing a Teflon liner to be fitted with a jump liner, take the following steps to install
the pieces into the gun:

1. Remove the gas nozzle and loosen the set
screw in the gas diffuser and the rear feeder
power plug and remove the conductor tube
from the gun by twisting the handle locking
nut in a counterclockwise direction. Pull
the conduit stop free from the rear feeder
power plug, but do not remove liner from
the gun.

2. Remove the brass conduit cap from the end
of the liner by twisting in a counterclockwise
direction.

3. The jump liner is supplied in 10" lengths
but may be cut shorter with a pair of wire
cutters. Check for sharp edges or burrs
in the cut end of the jump liner prior to
installing, failure to do so will cause poor
wire feed.

4. The jump liner is connected by the same
internal thread as the conduit cap. It can
be installed to the end of the teflon liner by
twisting in a clockwise direction.

5. Install conductor tube in the front of the
handle and secure with the locking nut by
twisting in a clockwise direction (this should
slide the liner/jump liner back into the gun.
Use caution so as not to bend or kink liner
or jump liner).

and secure with the diffuser set screw. If
unsure whether the liner is seated properly
in the diffuser, remove the set screw and
check to see if the liner is visible inside
the set screw hole. Do not overtighten on
the jump liner as the bronze material will
collapse under extreme pressure.

7. To secure the back end of the liner, push the conduit stop into the rear feeder power plug
as far as it will go and trim liner flush with the back of the conduit stop.

8. Firmly press end of conduit stop against
a solid surface and lock in place with set
screw. Stop is collet style and will compress
over the liner when fully pushed into plug.

8.06 STEP-BY-STEP BARE TEFLON LINER INSTALLATION

When installing a Teflon liner without the brass conduit cap the following steps are taken to
install the pieces into the gun:

1. Remove the gas nozzle and loosen the set screw in the gas diffuser and the rear feeder
power plug and remove the old liner from the gun.

2. Remove the conductor tube from the gun
by twisting the handle locking nut in a
counterclockwise direction.

3. Gently feed the new liner into the gun with
short strokes, taking care not to kink the
liner. If the liner hangs up inside the gun,
twist in a clockwise direction while gently
pushing.

3" - 4"

(7cm-10cm)

a. Correct Liner Feed Method:

Use short strokes

4. Attach conductor tube to front of handle and secure by twisting the locking nut in a
clockwise direction.

5. When the set screw cap is seated all the
way in the gas diffuser, lock in place with
the diffuser set screw. If unsure whether
the liner is seated properly in the diffuser,
remove the set screw and check to see if
the set screw cap is visible inside the set
screw hole. Gently tighten the set screw in
the diffuser. This connection must be snug.
Do not over-tighten or the liner may become
pinched; this will cause poor wire feed.
