D Additional safety precautions are required when any of the follow-

ing 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 D C 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!

FUMES AND GASES can be hazardous.

F)

d

r
t

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 op-

erations. 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 mate-

rial (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.

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 by-

pass 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 ME TA L o r 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 o f f compressed gas supply when not in use.
D Always ventilate confined spaces or use

approved air-supplied respirator.

can affect Implanted Medical Devices.

D Wearers of Pacemakers and other Implante

Medical Devices should keep away.

D Implanted Medical Device wearers should consult their docto

and the device manufacturer before going near arc welding, spo
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 lev-

el is high.

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

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.

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.

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.

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

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 d u 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-273242 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 chauf fage par induc­tion. Si le médecin approuve, il est recommandé de suivre les
procédures précédentes.

Notes

SECTION 8 − PROGRAMMING

To enter the SETUP MENU press and re­lease the SETUP button. The SETUP

MENU INDICATOR and the SETUP
BUTTON INDICATOR will illuminate.

Rotate the LEFT ADJUST KNOB to select
different menu items shown in the LEFT

DISPLAY. Rotate the RIGHT ADJUST
KNOB to change menu item values shown

in the RIGHT DISPLAY.
To exit the SETUP MENU press and re-

lease the SETUP button.
Items that can be adjusted in this menu are:
Trigger Control (TRIG) − Sets the gun

trigger control. The trigger control can be
configured as (STD, HOLD, or SPOT).

Trigger Hold Delay (HOLD) − Additional
trigger setting only appearing in the menu
when the trigger control is set to (TRIG
HOLD). T rigger hold delay time is the min­imum amount of time the trigger must be
held for trigger hold to become active.
There is a built in maximum trigger hold
time which the trigger must be released
within for trigger hold to become active.
The maximum trigger hold time is always

4.0 seconds after the trigger hold delay
time. For Example, if the trigger hold delay
time is set to 2.0 seconds, the trigger must
be held for at least 2.0 seconds and re­leased within 6.0 seconds for trigger hold to
become active. Once the trigger hold func­tion is active, the wire feeder will continue
feeding wire until the trigger is pressed and
released again.

Trigger 4T − Allows the operator to select
between weld parameters and crater pa­rameters using the gun trigger. Crater time
must be set for at least 0.2 seconds to

make this function operational. If gun trig­ger is released during welding the unit goes
into trigger hold - pressing and holding trig­ger again will cause the unit to stay in crater
until trigger is released and crater parame­ter times out.

Trigger Spot Time (SPOT) − Additional
trigger setting only appearing in the menu
when the trigger control is set to (TRIG
SPOT). The SPOT time is the length of
combined time for the start (if applicable)
and the weld sequence. The weld will end
when the set time has expired or the trigger
has been released, whichever occurs first.
The spot time is reset when the trigger is re­leased.

Remote Process Select

. A Remote Process Select capable

power source automatically switches
to the selected weld process when this
option is changed at the wire feeder.
The wire and gas program selections
for each weld process must be set at
the power source.

. When Trigger Schedule Select (see

Section 8-2) is enabled, the Weld Pro­cess option can be set independently
for each schedule. This allows the op­erator to remotely change the weld
process at the wire feeder and power
source with a single tap of the welding
gun trigger.

Preflow (PRE) − The amount of time that
the shielding gas will flow after the trigger
is pressed and before the welding arc will
be allowed to be active. Range of this set­ting is from (0.0 to 5.0) seconds.

Postflow (POST) − The amount of time
that the shielding gas will flow after the arc
has been shut off. Range of this setting is
from (0.0 to 10.0) seconds.

Run−In Speed (R−IN) − The wire feed
speed prior to the welding arc being struck.
This setting is a percentage of the wire feed
speed the unit is set to for welding. Range
of this setting is from (X0.10 to X0.99 to
OFF). Example: If the weld wire speed is
200 and R−IN is X0.50, the run−in wire
speed is 10 0 .

Burnback (B.BAK) − Burnback sets a
time from 0 to 0.25 seconds in increments
of 0.01 seconds. This is the time that the
arc is allowed to stay on after the wire stops
feeding.

Burnback Volts (VLTS) − Sets the voltage
used for burnback. The range is the same
as the selected power source. Measured in

0.1 volt increments.
Retract (RTRK) − When enabled, the user

can set a distance in inches from 0 to 1.5
inches. This is the distance the wire will
backup after welding stops.

Profile Pulse ON/OFF − When Profile
Pulse is On, the pulse parameters and wire
speed are coordinated to produce a con­sistent ripple pattern.

. Additional PROFILE PULSE menu

items may appear in the SETUP
MENU when PROFILE PULSE is act-

ive. See Section 8-7.

are locked and cannot be adjusted. At­tempting to change a locked parameter
causes the display to momentarily display
(LOCK).

Range Limits (LMTS) − When set to (ON),
the wire feed speed and arc length or
voltage weld settings are limited to minim­um and maximum adjustable ranges. The
minimum and maximum range settings ap­pear next in the menu when (LMTS) is set
to (ON). When set to (OFF), range limits are
inactive and do not appear in the menu.

Wire Feed Range Limit (MIN) − Indicated
in the LEFT DISPLAY with the WIREFEED
SPEED INDICATOR illuminated. Sets the
minimum wire feed speed. Range of this
setting is from 70 to 780 IPM.

Wire Feed Range Limit (MAX) − Indicated
in the LEFT DISPLAY with the WIREFEED
SPEED INDICATOR illuminated. Sets the
maximum wire feed speed. Range of this
setting is from (MIN) setting to 780 IPM.

Arc Length Range Limit (MIN) − Indicated
in the LEFT DISPLAY with the ARC
LENGTH INDICATOR illuminated. Sets the
minimum arc length. Range of this setting is
from 0 to 100.

Arc Length Range Limit (MAX) − Indic­ated in the LEFT DISPLAY with the ARC
LENGTH INDICATOR illuminated. Sets the
maximum arc length. Range of this setting
is from (MIN) setting to 100.

. When the Pulse Display (PULS) option

in the SETUP MENU LEVEL 2 is set to
(VOLT), the Arc Length Range Limits
are replaced by Voltage Range Limits.

Voltage Range Limit (MIN) − Indicated in
the LEFT DISPLAY with the VOLTS
INDICATOR illuminated. Sets the minimum
voltage. Range of this setting is dependent
on the power source voltage range in the
MIG process, and varies with the selected
wire and gas program in the PULSED MIG

process. If the power source weld process
is set to PULSED MIG, the minimum
voltage range limit setting will change if the
wire and gas program selection is changed.

Voltage Range Limit (MAX) − Indicated in
the LEFT DISPLAY with the VOLTS
INDICATOR illuminated. Sets the maxim­um voltage. Range of this setting is depend­ent on the power source voltage range in
the MIG process, and varies with the selec­ted wire and gas program in the PULSED
MIG process. If the power source weld pro­cess is set to PULSED MIG, the maximum
voltage range limit setting will change if the
wire and gas program selection is changed.

Power Source Synergic Mode (PWR.S) −

8-7. Profile Pulse

Profile Pulse optimizes Aluminum weld
bead appearance by producing welds with
consistently spaced ripple patterns, similar
to GTAW. This feature has been designed
to operate in a Synergic Pulsed MIG sys­tem. The consistent ripple pattern is
achieved b y periodically changing both the
wire feed speed and power level. The aver­age wire feed speed is determined by the
value the unit is set to for welding.

. By default, Profile Pulse parameters

are hidden from the Setup Menu. To
view the parameters, the (PROF) set­ting in the Setup Menu Level 2 must be

set to (YES). See section 8-2.

Profile Pulse Items that can be adjusted in
the Setup Menu are:

Profile Pulse ON/OFF (PROF) − Allows
Profile Pulse to be turned on or off.

Profile Pulse Frequency (P.FRQ) − Sets
the spacing between ripples in the weld
bead. Range of this setting is from (0.1 to

5.0) pulses per second. See Figures 1 and
2 below.

Profile Pulse Wire Feed Speed Change
(P.WFS) − Sets the percentage of change

above and below the wire feed speed the

unit is set to for welding. Range of this set­ting is (X0.00 to X0.30). Example: If the wire
feed speed is 200 and (P.WFS) is set to
(X0.10), the wire feed speed will alternate
between 180 and 220 ipm.

Profile Pulse Arc Length (P.AL) − Sets an
arc length correction factor for the lower
wire feed speed. This setting is a percent­age of the arc length the unit is set to for
welding. Range of this setting is from (X0.5
to X1.5). Example: If the arc length for weld­ing is set to 50 and (P.AL) is set to (X1.1),
the arc length setting for the lower wire feed
speed is 55 .

Constant travel speed with P.FRQ set to 0.1

Miller’s True Blue® Limited Warranty shall not apply to:

3. Equipment that has been modified by any party other than

and necessary maintenance, or equipment which has
been used for operation outside of the specifications for
the equipment.

MILLER PRODUCTS ARE INTENDED FOR PURCHASE AND
USE BY COMMERCIAL/INDUSTRIAL USERS AND PERSONS
TRAINED AND EXPERIENCED IN THE USE AND
MAINTENANCE OF WELDING EQUIPMENT.

In the event of a warranty claim covered by this warranty, the
exclusive remedies shall be, at Miller’s option: (1) repair; or (2)

as determined by Miller. Therefore no compensation or
reimbursement for transportation costs of any kind will be allowed.

TO THE EXTENT PERMITTED BY LAW, THE REMEDIES
PROVIDED HEREIN ARE THE SOLE AND EXCLUSIVE
REMEDIES. IN NO EVENT SHALL MILLER BE LIABLE FOR
DIRECT, INDIRECT, SPECIAL, INCIDENTAL OR

MILLER.

Some states in the U.S.A. do not allow limitations of how long an
implied warranty lasts, or the exclusion of incidental, indirect,
special or consequential damages, so the above limitation or
exclusion may not apply to you. This warranty provides specific
legal rights, and other rights may be available, but may vary from
state to state.

In Canada, legislation in some provinces provides for certain
additional warranties or remedi es o th er th a n a s s t at ed he r ei n, and to
the extent that they may not be waived, the limitations and
exclusions set out above may not apply. This Limited Warranty
provides specific legal rights, and other rights may be available, but
