hazards.
1-2. Arc Welding Hazards
The symbols shown below are used throughout this manual
to call attention to and identify possible hazards. When you
see the symbol, watch out, and follow the related instructions
to avoid the hazard. The safety information given below is
only a summary of the more complete safety information
found in the Safety Standards listed in Section 1-5. Read and
follow all Safety Standards.
Only qualified persons should install, operate, maintain, and
repair this unit.
During operation, keep everybody, especially children, away.
ELECTRIC SHOCK can kill.
Touching live electrical parts can cause fatal shocks
or severe burns. The electrode and work circuit is
electrically live whenever the output is on. The input
power circuit and machine internal circuits are also
live when power is on. In semiautomatic or automatic
wire welding, the wire, wire reel, drive roll housing,
and all metal parts touching the welding wire are
electrically live. Incorrectly installed or improperly
grounded equipment is a hazard.
D Do not touch live electrical parts.
D Wear dry, hole-free insulating gloves and body protection.
D Insulate yourself from work and ground using dry insulating mats
or covers big enough to prevent any physical contact with the work
or ground.
D Do not use AC output in damp areas, if movement is confined, or if
there is a danger of falling.
D Use AC output ONLY if required for the welding process.
D If AC output is required, use remote output control if present on
unit.
D Additional safety precautions are required when any of the following electrically hazardous conditions are present: 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; or when there is a high risk of unavoidable or accidental contact with the workpiece or ground. For these
conditions, use the following equipment in order presented: 1) a
semiautomatic DC constant voltage (wire) welder, 2) a DC manual
(stick) welder, or 3) an AC welder with reduced open-circuit voltage. In most situations, use of a DC, constant voltage wire welder
is recommended. And, do not work alone!
D Disconnect input power or stop engine before installing or
servicing this equipment. Lockout/tagout input power according to
OSHA 29 CFR 1910.147 (see Safety Standards).
D Properly install, ground, and operate this equipment according to
its Owner’s Manual and national, state, and local codes.
D Always verify the supply ground − check and be sure that input
power cord ground wire is properly connected to ground terminal in
disconnect box or that cord plug is connected to a properly
grounded receptacle outlet.
D When making input connections, attach proper grounding conductor first − double-check connections.
D Keep cords dry, free of oil and grease, and protected from hot metal
and sparks.
D Frequently inspect input power cord and ground conductor for
damage or bare wiring – replace immediately if damaged – bare
wiring can kill.
D Turn off all equipment when not in use.
D Do not use worn, damaged, undersized, or repaired cables.
D Do not drape cables over your body.
D If earth grounding of the workpiece is required, ground it directly
with a separate cable.
D Do not touch electrode if you are in contact with the work, ground,
or another electrode from a different machine.
D Do not touch electrode holders connected to two welding machines at the same time since double open-circuit voltage will be
present.
D Use only well-maintained equipment. Repair or replace damaged
parts at once. Maintain unit according to manual.
D Wear a safety harness if working above floor level.
D Keep all panels and covers securely in place.
D Clamp work cable with good metal-to-metal contact to workpiece
or worktable as near the weld as practical.
D Insulate work clamp when not connected to workpiece to prevent
contact with any metal object.
D Do not connect more than one electrode or work cable to any
single weld output terminal. Disconnect cable for process not in
use.
D Use GFCI protection when operating auxiliary equipment in damp
or wet locations.
SIGNIFICANT DC VOLTAGE exists in inverter welding power sources AFTER removal of input power.
D Turn Off inverter, disconnect input power, and discharge input
capacitors according to instructions in Maintenance Section
before touching any parts.
HOT PARTS can burn.
D Do not touch hot parts bare handed.
D Allow cooling period before working on
equipment.
D To handle hot parts, use proper tools and/or wear heavy, insulated welding gloves and clothing to prevent burns.
OM- 216869 Page 1
FUMES AND GASES can be hazardous.
Welding produces fumes and gases. Breathing
these fumes and gases can be hazardous to your
health.
D Keep your head out of the fumes. Do not breathe the fumes.
D If inside, ventilate the area and/or use local forced ventilation at the
arc to remove welding fumes and gases. The recommended way
to determine adequate ventilation is to sample for the composition
and quantity of fumes and gases to which personnel are exposed.
D If ventilation is poor, wear an approved air-supplied respirator.
D Read and understand the Safety Data Sheets (SDSs) and the
manufacturer’s instructions for adhesives, coatings, cleaners,
consumables, coolants, degreasers, fluxes, and metals.
D Work in a confined space only if it is well ventilated, or while
wearing an air-supplied respirator. Always have a trained watchperson nearby. Welding fumes and gases can displace air and
lower the oxygen level causing injury or death. Be sure the breathing air is safe.
D Do not weld in locations near degreasing, cleaning, or spraying operations. The heat and rays of the arc can react with vapors to form
highly toxic and irritating gases.
D Do not weld on coated metals, such as galvanized, lead, or
cadmium plated steel, unless the coating is removed from the weld
area, the area is well ventilated, and while wearing an air-supplied
respirator. The coatings and any metals containing these elements
can give off toxic fumes if welded.
ARC RAYS can burn eyes and skin.
Arc rays from the welding process produce intense
visible and invisible (ultraviolet and infrared) rays
that can burn eyes and skin. Sparks fly off from the
weld.
D Wear an approved welding helmet fitted with a proper shade of
filter lenses to protect your face and eyes from arc rays and
sparks when welding or watching (see ANSI Z49.1 and Z87.1
listed in Safety Standards).
D Wear approved safety glasses with side shields under your
helmet.
D Use protective screens or barriers to protect others from flash,
glare and sparks; warn others not to watch the arc.
D Wear body protection made from durable, flame−resistant material (leather, heavy cotton, wool). Body protection includes
oil-free clothing such as leather gloves, heavy shirt, cuffless
trousers, high shoes, and a cap.
WELDING can cause fire or explosion.
Welding on closed containers, such as tanks,
drums, or pipes, can cause them to blow up. Sparks
can fly off from the welding arc. The flying sparks, hot
workpiece, and hot equipment can cause fires and
burns. Accidental contact of electrode to metal objects can cause
sparks, explosion, overheating, or fire. Check and be sure the area is
safe before doing any welding.
D Remove all flammables within 35 ft (10.7 m) of the welding arc. If
this is not possible, tightly cover them with approved covers.
D Do not weld where flying sparks can strike flammable material.
D Protect yourself and others from flying sparks and hot metal.
D Be alert that welding sparks and hot materials from welding can
easily go through small cracks and openings to adjacent areas.
D Watch for fire, and keep a fire extinguisher nearby.
D Be aware that welding on a ceiling, floor, bulkhead, or partition can
cause fire on the hidden side.
D Do not weld on containers that have held combustibles, or on
closed containers such as tanks, drums, or pipes unless they are
properly prepared according to AWS F4.1 and AWS A6.0 (see
Safety Standards).
D Do not weld where the atmosphere can contain flammable dust,
gas, or liquid vapors (such as gasoline).
D Connect work cable to the work as close to the welding area as
practical to prevent welding current from traveling long, possibly
unknown paths and causing electric shock, sparks, and fire
hazards.
D Do not use welder to thaw frozen pipes.
OM- 216869 Page 2
D Remove stick electrode from holder or cut off welding wire at
contact tip when not in use.
D Wear body protection made from durable, flame−resistant material
(leather, heavy cotton, wool). Body protection includes oil-free
clothing such as leather gloves, heavy shirt, cuffless trousers, high
shoes, and a cap.
D Remove any combustibles, such as a butane lighter or matches,
from your person before doing any welding.
D After completion of work, inspect area to ensure it is free of sparks,
glowing embers, and flames.
D Use only correct fuses or circuit breakers. Do not oversize or bypass them.
D Follow requirements in OSHA 1910.252 (a) (2) (iv) and NFPA 51B
for hot work and have a fire watcher and extinguisher nearby.
D Read and understand the Safety Data Sheets (SDSs) and the
manufacturer’s instructions for adhesives, coatings, cleaners,
consumables, coolants, degreasers, fluxes, and metals.
FLYING METAL or DIRT can injure eyes.
D Welding, chipping, wire brushing, and grinding
cause sparks and flying metal. As welds cool,
they can throw off slag.
D Wear approved safety glasses with side
shields even under your welding helmet.
BUILDUP OF GAS can injure or kill.
D Shut off compressed gas supply when not in use.
D Always ventilate confined spaces or use
approved air-supplied respirator.
ELECTRIC AND MAGNETIC FIELDS (EMF)
can affect Implanted Medical Devices.
D Wearers of Pacemakers and other Implanted
Medical Devices should keep away.
D Implanted Medical Device wearers should consult their doctor
and the device manufacturer before going near arc welding, spot
welding, gouging, plasma arc cutting, or induction heating
operations.
NOISE can damage hearing.
Noise from some processes or equipment can
damage hearing.
D Wear approved ear protection if noise level is high.
CYLINDERS can explode if damaged.
Compressed gas cylinders contain gas under high
pressure. If damaged, a cylinder can explode. Since
gas cylinders are normally part of the welding
process, be sure to treat them carefully.
D Protect compressed gas cylinders from excessive heat, mechanical shocks, physical damage, slag, open flames, sparks, and arcs.
D Install cylinders in an upright position by securing to a stationary
support or cylinder rack to prevent falling or tipping.
D Keep cylinders away from any welding or other electrical circuits.
D Never drape a welding torch over a gas cylinder.
D Never allow a welding electrode to touch any cylinder.

1-6. EMF Information
Electric current flowing through any conductor causes localized electric
and magnetic fields (EMF). The current from arc welding (and allied processes including spot welding, gouging, plasma arc cutting, and
induction heating operations) creates an EMF field around the welding
circuit. EMF fields can interfere with some medical implants, e.g. pacemakers. Protective measures for persons wearing medical implants
have to be taken. For example, restrict access for passers−by or conduct individual risk assessment for welders. All welders should use the
following procedures in order to minimize exposure to EMF fields from
the welding circuit:
1. Keep cables close together by twisting or taping them, or using a
cable cover.
2. Do not place your body between welding cables. Arrange cables
to one side and away from the operator.
3. Do not coil or drape cables around your body.
OM- 216869 Page 4
4. Keep head and trunk as far away from the equipment in the
welding circuit as possible.
5. Connect work clamp to workpiece as close to the weld as
possible.
6. Do not work next to, sit or lean on the welding power source.
7. Do not weld whilst carrying the welding power source or wire
feeder.
About Implanted Medical Devices:
Implanted Medical Device wearers should consult their doctor and the
device manufacturer before performing or going near arc welding, spot
welding, gouging, plasma arc cutting, or induction heating operations.
If cleared by your doctor, then following the above procedures is recommended.

LES FUMÉES ET LES GAZ peuvent
être dangereux.
Le soudage génère des fumées et des gaz. Leur
inhalation peut être dangereux pour votre santé.
D Eloigner votre tête des fumées. Ne pas respirer les fumées.
D À l’intérieur, ventiler la zone et/ou utiliser une ventilation forcée au
niveau de l’arc pour l’évacuation des fumées et des gaz de
soudage. Pour déterminer la bonne ventilation, il est recommandé
de procéder à un prélèvement pour la composition et la quantité
de fumées et de gaz auxquels est exposé le personnel.
D Si la ventilation est médiocre, porter un respirateur anti-vapeurs
approuvé.
D Lire et comprendre les fiches de données de sécurité et les instructions du fabricant concernant les adhésifs, les revêtements, les
nettoyants, les consommables, les produits de refroidissement, les
dégraisseurs, les flux et les métaux.
D Travailler dans un espace fermé seulement s’il est bien ventilé ou
en portant un respirateur à alimentation d’air. Demander toujours à
un surveillant dûment formé de se tenir à proximité. Des fumées et
des gaz de soudage peuvent déplacer l’air et abaisser le niveau
d’oxygène provoquant des blessures ou des accidents mortels.
S’assurer que l’air de respiration ne présente aucun danger.
D Ne pas souder dans des endroits situés à proximité d’opérations
de dégraissage, de nettoyage ou de pulvérisation. La chaleur et
les rayons de l’arc peuvent réagir en présence de vapeurs et former des gaz hautement toxiques et irritants.
D Ne pas souder des métaux munis d’un revêtement, tels que l’acier
galvanisé, plaqué en plomb ou au cadmium à moins que le revêtement n’ait été enlevé dans la zone de soudure, que l’endroit soit
bien ventilé, et en portant un respirateur à alimentation d’air. Les
revêtements et tous les métaux renfermant ces éléments peuvent
dégager des fumées toxiques en cas de soudage.
LES RAYONS DE L’ARC peuvent
provoquer des brûlures dans les
yeux et sur la peau.
Le rayonnement de l’arc du procédé de soudage génère
des rayons visibles et invisibles intenses (ultraviolets e
infrarouges) susceptibles de provoquer des brûlures dans les yeux et sur la
peau. Des étincelles sont projetées pendant le soudage.
D Porter un casque de soudage approuvé muni de verres filtrants
approprié pour protéger visage et yeux pour protéger votre visage
et vos yeux pendant le soudage ou pour regarder (voir ANSI Z49.1
et Z87.1 énuméré dans les normes de sécurité).
D Porter des lunettes de sécurité avec écrans latéraux même sous
votre casque.
D Avoir recours à des écrans protecteurs ou à des rideaux pour
protéger les autres contre les rayonnements les éblouissements
et les étincelles ; prévenir toute personne sur les lieux de ne pas
regarder l’arc.
D Porter un équipement de protection pour le corps fait d’un matériau
résistant et ignifuge (cuir, coton robuste, laine). La protection du
corps comporte des vêtements sans huile comme par ex. des
gants de cuir, une chemise solide, des pantalons sans revers, des
chaussures hautes et une casquette.
LE SOUDAGE peut provoquer un
incendie ou une explosion.
Le soudage effectué sur des conteneurs fermés tels
que des réservoirs, tambours ou des conduites peut
provoquer leur éclatement. Des étincelles peuvent
être projetées de l’arc de soudure. La projection d’étincelles, des
pièces chaudes et des équipements chauds peut provoquer des incendies et des brûlures. Le contact accidentel de l’électrode avec des
objets métalliques peut provoquer des étincelles, une explosion, un surOM-216869 Page 6
chauffement ou un incendie. Avant de commencer le soudage, vérifier
et s’assurer que l’endroit ne présente pas de danger.
D Déplacer toutes les substances inflammables à une distance de
10,7 m de l’arc de soudage. En cas d’impossibilité les recouvrir
soigneusement avec des protections homologués.
D Ne pas souder dans un endroit là où des étincelles peuvent tomber
sur des substances inflammables.
D Se protéger et d’autres personnes de la projection d’étincelles et
de métal chaud.
D Des étincelles et des matériaux chauds du soudage peuvent
facilement passer dans d’autres zones en traversant de petites
fissures et des ouvertures.
D Surveiller tout déclenchement d’incendie et tenir un extincteur à
proximité.
D Le soudage effectué sur un plafond, plancher, paroi ou séparation
peut déclencher un incendie de l’autre côté.
D Ne pas effectuer le soudage sur des conteneurs fermés tels que
des réservoirs, tambours, ou conduites, à moins qu’ils n’aient été
préparés correctement conformément à AWS F4.1 et AWS A6.0
(voir les Normes de Sécurité).
D Ne pas souder là où l’air ambiant pourrait contenir des poussières,
gaz ou émanations inflammables (vapeur d’essence, par exemple).
D Brancher le câble de masse sur la pièce le plus près possible de la
zone de soudage pour éviter le transport du courant sur une
longue distance par des chemins inconnus éventuels en provoquant des risques d’électrocution, d’étincelles et d’incendie.
D Ne pas utiliser le poste de soudage pour dégeler des conduites gelées.
D En cas de non utilisation, enlever la baguette d’électrode du porteélectrode ou couper le fil à la pointe de contact.
D Porter un équipement de protection pour le corps fait d’un matériau
résistant et ignifuge (cuir, coton robuste, laine). La protection du
corps comporte des vêtements sans huile comme par ex. des
gants de cuir, une chemise solide, des pantalons sans revers, des
chaussures hautes et une casquette.
D Avant de souder, retirer toute substance combustible de vos poches telles qu’un allumeur au butane ou des allumettes.
D Une fois le travail achevé, assurez−vous qu’il ne reste aucune
trace d’étincelles incandescentes ni de flammes.
D Utiliser exclusivement des fusibles ou coupe−circuits appropriés.

2-6. Informations relatives aux CEM
Le courant électrique qui traverse tout conducteur génère des champs
électromagnétiques (CEM) à certains endroits. Le courant issu d’un
soudage à l’arc (et de procédés connexes, y compris le soudage par
points, le gougeage, le découpage plasma et les opérations de
chauffage par induction) crée un champ électromagnétique (CEM)
autour du circuit de soudage. Les champs électromagnétiques produits
peuvent causer interférence à certains implants médicaux, p. ex. les
stimulateurs cardiaques. Des mesures de protection pour les porteurs
d’implants médicaux doivent être prises: Limiter par exemple tout accès
aux passants ou procéder à une évaluation des risques individuels pour
les soudeurs. Tous les soudeurs doivent appliquer les procédures
suivantes pour minimiser l’exposition aux CEM provenant du circuit de
soudage:
1. Rassembler les câbles en les torsadant ou en les attachant avec
du ruban adhésif ou avec une housse.
2. Ne pas se tenir au milieu des câbles de soudage. Disposer les
OM-216869 Page 8
câbles d’un côté et à distance de l’opérateur.
3. Ne pas courber et ne pas entourer les câbles autour de votre
corps.
4. Maintenir la tête et le torse aussi loin que possible du matériel du
circuit de soudage.
5. Connecter la pince sur la pièce aussi près que possible de la
soudure.
6. Ne pas travailler à proximité d’une source de soudage, ni
s’asseoir ou se pencher dessus.
7. Ne pas souder tout en portant la source de soudage ou le
dévidoir.
En ce qui concerne les implants médicaux :
Les porteurs d’implants doivent d’abord consulter leur médecin avant
de s’approcher des opérations de soudage à l’arc, de soudage par
points, de gougeage, du coupage plasma ou de chauffage par induction. Si le médecin approuve, il est recommandé de suivre les
procédures précédentes.

Press switch pad until desired process LED is illuminated:
TIG HF Impulse - is a pulsed HF
(see Section 6-7) arc starting method that can be used with either AC
or DC TIG welding. Make connections according to Section 5-10.
TIG Lift-Arct - is an arc starting
method in which the electrode must
come in contact with the workpiece
(see Section 6-7). This method can
be used with either AC or DC TIG
welding. Make connections according to Section 5-10.
1
Stick (SMAW) - This method can
be used with either AC or DC Stick
welding. Make connections according to Section 5-12.
6-7. Lift-Arc And HF TIG Start Procedures
Lift-Arc Start
When Lift-Arct button light is On,
start arc as follows:
Lift-Arc Start Method
1
“Touch”
1−2
Seconds
2
1
TIG Electrode
2
Workpiece
Touch tungsten electrode to workpiece at weld start point, enable output and shielding gas with torch trigger, foot control, or hand control. Hold
electrode to workpiece for 1-2 seconds, and slowly lift electrode. Arc is
formed when electrode is lifted.
Normal open-circuit voltage is not
present before tungsten electrode
touches workpiece; only a low sensing voltage is present between electrode and workpiece. The solid-state
output contactor does not energize
until after electrode is touching workpiece. This allows a properly prepared electrode (see Section 12-2) to
touch workpiece without overheating,
sticking, or getting contaminated.
Application:
Lift-Arc is used for the DCEN or AC
GTAW process when HF Start method is not permitted, or to replace the
scratch method.
Do NOT Strike Like A Match!
HF Start
When HF Start button light is On, start
arc as follows:
High frequency turns on to start arc
when output is enabled. High frequency turns off when arc is started,
and turns on whenever arc is broken
to help restart arc.
Application:
HF start is used for the DCEN GTAW,
or the AC GTAW process when a
non-contact arc starting method is
required.

. When a foot or finger remote current
control is connected, initial amps, initial slope, final slope, and final amps
are controlled by the remote control.
NOTE: If an On/Off type trigger is used, it
must be a maintained switch. All Sequencer functions become active, and must be
set by the operator.
RMT 2T HOLD
Application: Use Remote Trigger Hold
(2T) for long extended welds.
If a foot or finger current control is connected to the welding power source, only
trigger input is functional (see Section
7-4B).
. This switch function can be reconfigured for 3T, 4T, 4T Momentary, or
Mini Logic control See Sections 7-4C,
D, E, or F)

See Section 6-14 for all Pulser parameter ranges.
PPS - Pulse frequency or pulses per second, is the number of pulse cycles per second. Pulse frequency helps
reduce heat input, part warpage, and helps weld bead
cosmetics. The higher the PPS setting, the smoother the
ripple effect, the narrower the weld bead, and the more
cooling you get. By setting PPS on the lower end, the
pulse is slower, and the weld bead wider. This slow pulsing helps agitate the weld puddle to help release gas
trapped in the weldment, and help reduce porosity (very
useful in aluminum welding). Some beginners use a
slower pulse rate (2-4 pps) to help them with their timing
on adding filler material. An experienced welder may
have the PPS setting much higher, depending on their
personal preferences, and on what they are trying to accomplish.

PEAK t - (PEAK t) is the percentage of time in each cycle,
spent at peak amperage (main amperage). Peak amperage is set with the Amperage control (see Section 6-3).
If one pulse per second is being used, and peak time is
set at 50%, one-half second is spent at peak amperage,
and the other 50%, or one-half second, is spent at the
background amperage. Increasing peak time increases
time spent at peak amperage, which increases heat input
into the part. A good starting point for peak time is about
50-60%. To find a good ratio, you will have to experiment
a bit, but the idea is to decrease heat input into the part,
and increase the cosmetics of the weld.
BKGND A - (Background amps) is set as a percentage
of the peak amps setting. If peak amps is set at 200, and
background amps at 50%, your background amps is 100
amps when the machine pulses on the background side
of the cycle. The lower background amperage helps reduce heat input. Increasing or decreasing background
amps increases or decreases the overall average amperage, which helps determine how fluid your puddle is
on the background side of the pulse cycle. Overall, you
want your puddle to shrink to about one-half the size, but
still remain fluid. To start with, set background amps at
about 20-30% for stainless/carbon steel, or at about
35-50% for aluminum alloys.

Pulsed Output Waveforms
Example shows affect changing the Peak Time control
has on the pulsed output waveform.
Application:
Pulsing refers to the alternating raising and lowering of
the weld output at a specific rate. The raised portions of
the weld output are controlled in width, height, and frequency, forming pulses of weld output. These pulses and
the lower amperage level between them (called the background amperage) alternately heat and cool the molten
weld puddle. The combined effect gives the operator better control of penetration, bead width, crowning, undercutting, and heat input. Controls can be adjusted while
welding.
Pulsing can also be used for filler material addition technique training.

PREFLOW [PRE] - If the TIG HF process
is active (see Section 6-6) and Preflow is
shown on the control panel, use control to
set length of time gas flows before arc initiation.
Application: Preflow is used to purge
the weld area and aids in arc starts.
POST FLOW [POST] - If the TIG process
is active (see Section 6-6), use control to
set length of time gas flows after welding
stops.
1
AUTO POST FLOW - Creates a post
flow time scaled at 1 second per 10 amps
of the peak weld amperage for a given
weld cycle. Auto post flow is limited to a
8 second minimum, or to the maximum
preset post flow time.
Application:
Postflow is required to cool tungsten and
weld, and to prevent contamination of
tungsten and weld. Increase postflow
time if tungsten or weld are dark in appearance.
DIG - If Stick process is active (see Section 6-6), use control to set amount of
DIG. When set at 0, short-circuit amperage at low arc voltage is the same as normal welding amperage.
When setting is increased, short-circuit
amperage at low arc voltage increases.
Application:
Control helps arc starting or making vertical or overhead welds by increasing amperage at low arc voltage, and reduces
electrode sticking while welding.
PURGE [PURG] - To activate the gas
valve and start the purge function, push
and hold the Gas/DIG switch pad for the
desired amount of time. To set from 1 to
50 seconds of purge time, hold the Gas/
DIG switch pad while turning the encoder
control. Default is 0.
While Purge is active, [PURG] is shown
in the left display, and purge time is
shown in the right display.
Pressing any switch pad will end the
purge display, but gas will continue to flow
until the preset time has timed out.
Application: Purge is used to clear the
gas lines.

Note: See Section 7-1 to set same Amplitude
control [ENEP].
EN Amperage and EP Amperage allow the operator the ability to control the amount of amperage in the negative and positive half cycles
independently. A 1.5 to 1 ratio of EN to EP is a
good starting point. This provides cleaning action, but directs more energy into the workpiece
and provides faster travel speeds.

Amperage Control
Average Amperage Control: Setting EN Amperage, EP Amperage, Balance, and Frequency values creates an average amperage. The
operator can change the average amperage
value while maintaining the same EN amperage to EP amperage ratio at the existing balance and frequency. To change the average
amperage value, press the Amperage switch
pad and turn the Encoder control. The changing average value is displayed on the ammeter.
Example: If EN Amperage is 300, EP Amperage is 150, Balance is 60%, and Frequency is
120, the average amperage is 240 amps. If you
press the Amperage switch pad and turn the
Encoder control until 480 amps is displayed,
the EN amperage is now 600 and EP amperage is now 300. The balance remains 60%, and
the frequency is still 120, and the 2 to 1 EN amperage to EP amperage is maintained.
Balance [BAL] - AC Balance control is enabled
only in AC TIG to set percentage of time polarity
is electrode negative. Set control at about 75%,
and fine tune from there.
5
Voltmeter
Displays word abbreviations of selected parameters.
Application:
When welding on oxide forming materials such
as aluminum or magnesium, excess cleaning
is not necessary. To produce a good weld, only
0.10 in (2.5mm) of etched zone along the weld
toes is required.
Use AC Balance to control the etch zone width.
Joint configuration, set-up, process variables,
and oxide thickness may affect setting.
AC Frequency [FREQ] - Use control to set AC
frequency (cycles per second).
Application:
AC Frequency controls arc width and directional control. As AC frequency decreases, the arc
becomes wider and less focused, limiting directional control. As AC frequency increases,
the arc becomes narrower and more focused,
increasing directional control. Travel speed
can increase as AC frequency increases.

1 3T (Specific Trigger Operation)
Sequencer is required to reconfigure for 3T.
3T requires a specific type of remote control with two independent momentarycontact switches. One will be designated
initial switch, and it must be connected between Remote 14 receptacle pins A and B.
The second will be designated as the final
switch, and it must be connected between
Remote 14 receptacle pins D and E.
2 Encoder Control
To select 3T, turn Encoder control.
Definitions:
Initial slope rate is the rate of amperage
change determined by the initial amperage,
initial slope time, and main amperage.
Final slope rate is the rate of amperage
change determined by the main amperage, final slope time, and final amperage.
Operation:
C. When main amperage level is reached,
initial switch can be released.
A. Press and release initial switch within 3/4
second to start shielding gas flow. To stop
the preflow sequence before preflow time
elapses (25 seconds), press and release
final switch. The preflow timer will reset
and the weld sequence can be started
again.
D. Press and hold the final switch to decrease amperage at final slope rate (release switch to weld at desired amperage
level).
E. When final amperage has been reached,
the arc extinguishes and shielding gas
flows for the time set on the Postflow control.
. If an initial switch closure is not made
again before preflow time ends, gas flow
stops, the timer resets, and an initial
switch press and release is necessary to
start the weld sequence again.
Application:
With the use of two remote switches instead
of potentiometers, 3T gives the operator the
ability to infinitely increase, decrease, or
pause and hold amperage within the range
determined by the initial, main, and final amperages.
B. Press initial switch to start arc at initial
amps. Holding switch will change amperage at initial slope rate (release switch to
weld at desired amperage level).

12-2. Preparing Tungsten Electrode For DC Electrode Negative (DCEN) Welding
Or AC Welding With Inverter Machines
Grinding the tungsten electrode produces dust and flying sparks which can cause injury and start fires.
Use local exhaust (forced ventilation) at the grinder or wear an approved respirator. Read MSDS for safety
information. Consider using tungsten containing ceria, lanthana, or yttria instead of thoria. Grinding dust
from thoriated electrodes contains low-level radioactive material. Properly dispose of grinder dust in an
environmentally safe way. Wear proper face, hand, and body protection. Keep flammables away.
