From Miller to You
Thank you and congratulations on choosing Miller. Now you can get
the job done and get it done right. We know you don’t have time to do
it any other way.
That’s why when Niels Miller first started building arc welders in 1929,
he made sure his products offered long-lasting value and superior
quality. Like you, his customers couldn’t afford anything less. Miller
products had to be more than the best they could be. They had to be the
best you could buy.
Today, the people that build and sell Miller products continue the
tradition. They’re just as committed to providing equipment and service
that meets the high standards of quality and value established in 1929.
This Owner’s Manual is designed to help you get the most out of your
Miller products. Please take time to read the Safety precautions. They
will help you protect yourself against potential hazards on the worksite.
We’ve made installation and operation quick
and easy. With Miller you can count on years
of reliable service with proper maintenance.
And if for some reason the unit needs repair,
there’s a Troubleshooting section that will
help you figure out what the problem is. The
parts list will then help you to decide the
exact part you may need to fix the problem.
Warranty and service information for your
particular model are also provided.
Miller is the first welding
equipment manufacturer in
the U.S.A. to be registered to
the ISO 9001 Quality System
Standard.
Miller Electric manufactures a full line
of welders and welding related equipment.

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 weld output in damp, wet, or confined spaces, 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 unit, disconnect input power, and discharge input capacitors according to instructions in Manual 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-253086 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 Ventilate the work 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.
OM-253086 Page 2
D Do not cut or weld on tire rims or wheels. Tires can explode if heated. Repaired rims and wheels can fail. See OSHA 29 CFR
1910.177 listed in Safety Standards.
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.
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.
D Never weld on a pressurized cylinder − explosion will result.
D Use only correct compressed gas cylinders, regulators, hoses,
and fittings designed for the specific application; maintain them
and associated parts in good condition.
D Turn face away from valve outlet when opening cylinder valve. Do
not stand in front of or behind the regulator when opening the valve.
D Keep protective cap in place over valve except when cylinder is in
use or connected for use.
D Use the proper equipment, correct procedures, and sufficient
number of persons to lift, move, and transport cylinders.
D Read and follow instructions on compressed gas cylinders,
associated equipment, and Compressed Gas Association (CGA)
publication P-1 listed in Safety Standards.

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-253086 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.

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 surchauffement ou un incendie. Avant de commencer le soudage, vérifier
et s’assurer que l’endroit ne présente pas de danger.

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-253086 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.

Failure to follow these electrical service guide recommendations could create an electric shock or fire hazard. These recommendations are for a dedicated circuit sized for the rated output and duty cycle of the welding power source.
In dedicated circuit installations, the National Electrical Code (NEC) allows the receptacle or conductor rating to be less than the rating
of the circuit protection device. All components of the circuit must be physically compatible. See NEC articles 210.21, 630.11, and
630.12.

B. Electrical Service Guide For Single-Phase Operation
Elec Serv 2017−01
Failure to follow these electrical service guide recommendations could create an electric shock or fire hazard. These recommendations are for a dedicated circuit sized for the rated output and duty cycle of the welding power source.
In dedicated circuit installations, the National Electrical Code (NEC) allows the receptacle or conductor rating to be less than the rating
of the circuit protection device. All components of the circuit must be physically compatible. See NEC articles 210.21, 630.11, and
630.12.

Controls Oxide Cleaning
Increasing setting reduces oxide cleaning. Range is

[FREQ]* Frequency Control:
Increasing setting narrows arc width. Range is 70 to
150 Hertz. (See tips below).
[POST] Post Flow Control:
Controls the length of time gas flows after welding
stops. Range is AUTO, OFF − 50T (seconds).
AUTO calculates the time based on the maximum
amperage of each welding cycle. The minimum time
is 8 seconds. Auto = maximum amperage/10.
TIP: AC Balance controls the cleaning
action. If floating black spots appear in
the puddle, the balance setting is too high.
Turn the balance down until puddle becomes clear.
TIP: AC Frequency controls the width of
the arc cone. For thin fillet welds (less
than 1/4 in.) set the frequency to 120 Hz.
This frequency setting provides a focused
stable arc and produces a narrow weld.
For outside corner or groove welds on
heavy material, a wide weld may be required. Lower the frequency to between
70 and100 Hz. This frequency setting produces a wider weld.

Sequencer Control
The welding output can be programmed to specific amperages and durations for repetitive applications. Sequencer
is only available in the TIG process. Sequencer is disabled
if a remote control with variable amperage is connected to
the machine.
[INTL] Initial Amperage: Range is min − 280 amps.
[ISLP] Initial Slope Time: Range is OFF − 50.0T (seconds).
[FSLP] Final Slope Time: Range is OFF − 50.0T
(seconds).
[FNL] Final Amperage: Range is min − 280 amps.
(See Sections 10-2 and 10-3 for setting weld time.)
Gas/DIG Control
[PRE] Preflow Time:
Controls length of time gas flows prior to arc start.
Range is OFF−25T (seconds).
[POST] Post Flow Time:
Increasing setting increases length of time gas flows after
welding stops. Range is OFF − 50T (seconds). AUTO calculates the time based on the maximum amperage of each
welding cycle. The minimum time is 8 seconds. Auto =
maximum amperage/10.
[DIG]* Arc Force Control:
Controls the amount of additional amperage at low voltage
(short arc length) conditions. Adjust the force of the arc for
different joint configurations and electrodes. Range is OFF
− 100%. PRO-Set values available for both 6010 and 7018
electrodes
CARBon ARC Gouging can be selected at one step above
DIG’s 100%.
[IND] Arc Control (Inductance) (Multiprocess Models)
Controls the dynamic properties of the arc to control the
puddle. The 0% setting gives a minimum inductance, that
is a stiff, fast responding arc, and a small, fast freezing
puddle. The 99% gives maximum inductance, that is a soft,
slow responding, low-spatter arc, and high puddle fluiditiy.
Use FLUXCORE setting for Self Shielded Flux Core.
Range: Solid wire 0-99% or FLUXCORE
Select a setting best suited for the application.
. Inductance adjustment may change polarity refer to
polarity selection above.
AC Waveshape Control
[BAL] Balance Control (%EN) TIG Only:
Controls oxide cleaning. Increasing the setting reduces
cleaning. Range is BALL, 50 − 99%. Stick is fixed at 50%.
“BALL” sets the Balance to 30%. This is to allow the operator to form a ball on the tip of the tungsten. It is not for normal welding operation. (See tips in Section 6-2).
[FREQ] AC Frequency (Hz):
Controls arc width. Increasing the setting narrows the arc
width. Range is 20 to 400 Hz. (See Section 6-2).

Independent Amperage Control (CE Models Only)
[ENEP] [SAME] - standard mode of operation for controlling AC amperage setting.
[ENEP] [INDP] - for AC TIG welding allows the user to set
the EP amperage independently from the EN amperage.
When [ON], the user can set the EP waveshape (sine,
square, triangle) independently from the EN waveshape
(see Section 7-4).
AC Waveshape Selection:
Use Encoder to select between advanced squarewave
[ADVS], soft squarewave [SOFT], sine wave [SINE], or
triangle wave [TRI]. The default is Soft.
Application: Use advance squarewave when a more
focused arc is required for better directional control. Use
soft squarewave when a softer arc with a more fluid
puddle is desired. Use sine wave to simulate a conventional power source. Use triangular waveshape when the
effects of peak amperage with reduced overall heat input
is required to help control distortion on thin materials.
Arc Starting Mode Selection (Stick)
[HOTS] [ON]
Provides additional amperage while striking the electrode to prevent the electrode from sticking.

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 150, EP Amperage is 100, Balance is 75%, and Frequency is
120, the average amperage is 138 amps. If you
press the Amperage switch pad and turn the Encoder control until 69 amps is displayed, the EN amperage is now 75 and EP amperage is now 50. The
balance remains 75%, and the frequency is still

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.
OM-253086 Page 56
Operation:
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.
. 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.
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).
C. When main amperage level is reached,
initial switch can be released.
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.
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.

15-2. 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.

16-1. Lift-Arc And HF TIG Start Procedures
Lift-Arc Start
When Lift-Arct button light is On,
start arc as follows:
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.
Lift-Arc Start Method
1
“Touch”
1−2
Seconds
2
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 electrode 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.
HF Start
When HF Start button light is On, start
arc as follows:
Do NOT Strike Like A Match!
High frequency turns on to help 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
process when a non-contact arc starting method is required.

Pulser Control
Pulsing is available while using the TIG process. Controls can be adjusted while welding.
Press switch pad to enable pulser.
ON - When illuminated, this LED indicates the pulser is
on.
Press switch pad until desired parameter LED is illuminated.
To turn Pulser off, press and release switch pad until the
On LED turns off.

See Section 7-2 or 9-2 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 9-1).
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.
