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,

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.
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 for damage or bare wiring −
replace cord immediately if damaged − bare wiring can kill.
D Turn off all equipment when not in use.
D Do not use worn, damaged, undersized, or poorly spliced cables.
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 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.
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-221 771 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.
D If ventilation is poor, wear an approved air-supplied respirator.
D Read and understand the Material Safety Data Sheets (MSDSs)
and the manufacturer’s instructions for metals, consumables,
coatings, cleaners, and degreasers.
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 protective clothing made from durable, flame-resistant
material (leather, heavy cotton, or wool) and foot protection.
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 may 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

1-6. EMF Information
Electric current flowing through any conductor causes localized electric
and magnetic fields (EMF). Welding current creates an EMF field
around the welding circuit and welding equipment. EMF fields may 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-221 771 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.

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.
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.
LES FUMÉES ET LES GAZ peuvent
être dangereux.
D Se protéger et d’autres personnes de la projection d’étincelles et
de métal chaud.
Le soudage génère des fumées et des gaz. Leur
inhalation peut être dangereux pour votre santé.
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 Eloigner votre tête des fumées. Ne pas respirer les fumées.
D Surveiller tout déclenchement d’incendie et tenir un extincteur à
proximité.
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

2-6. Informations relatives aux CEM
Le courant électrique qui traverse tout conducteur génère des champs
électromagnétiques (CEM) à certains endroits. Le courant de soudage
crée un CEM autour du circuit et du matériel de soudage. Les CEM
peuvent créer des interférences avec certains implants médicaux
comme des 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:
4. Maintenir la tête et le torse aussi loin que possible du matériel 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
câbles d’un côté et à distance de l’opérateur.
3. Ne pas courber et ne pas entourer les câbles autour de votre
corps.
En ce qui concerne les implants médicaux :
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.
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.

The method used to arrange cables has
a significant affect on welding
properties. As an example, Pro-pulse
and RMD welding processes can
produce high welding circuit inductance
depending on cable length and
arrangement. This can result in limited
current rise during droplet transfer into
the welding puddle.

The electrode sense lead is contained
in the feeder control cable and is
enabled for all processes. The work
sense lead connects to the welding
power source 4-pin connector located
above the negative output terminal. This
work sense lead automatically compensates for work cable voltage drop when
connected to the welding power source.

This arrangement is a bad setup due to

flow path of the welding arc. Interaction
between welding circuits will affect voltage
drop in the workpiece. The voltage drop
across the workpiece will not be measured
correctly for the voltage feedback signal.
Voltage feedback to the welding power
sources will not be correct at either sense

3-17. Electrical Service Guide
Elec Serv 2011−08
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.
NOTICE − INCORRECT INPUT POWER can damage this welding power source. This welding power source requires a CONTINUOUS supply of
input power at rated frequency(+10%) and voltage (+10%). Phase to ground voltage shall not exceed +10% of rated input voltage. Do not use a generator with automatic idle device (that idles engine when no load is sensed) to supply input power to this welding power source.
. Actual input voltage should not exceed ± 10% of indicated required input voltage. If actual input voltage is outside of this range, output may not
be available.

SECTION 4 − OPERATION
4-1. Operational Terms
The following is a list of terms and their definitions as they apply to this interface unit:
General Terms:
Adjust
Control knob used to change or set parameters and functions.
Amps
Indicates average amperage while welding and 3 seconds hold value at end of weld.
Arc Adjust
Term used to represent arc length adjustments in pulse programs. Increasing Arc Adjust increases the actual
arc length. Likewise, decreasing arc adjust shortens arc length. Arc Adjust is replaced by volts in MIG
programs.
Arc Control
Pressing this button will allow setting of inductance in MIG mode and sharp arc in pulse, Pro-pulse, and RMDPro. Also, this button allows setting dig in stick mode.
Arc Length
Distance from end of wire electrode to workpiece.
Flux Cored Arc Welding
Flux cored arc welding (FCAW) is a continuous electrode that is fed into the arc and depends on shielding gas
from either an external source or is generated from the decomposition of gas forming ingredients contained in
the electrode’s core.
Gas Type
Selection of shielding gas being used in application.
Gouging
The removal of molten metal from a workpiece surface using an electrode and gas source, such as in air carbon
arc gouging or plasma arc gouging.
Inductance
In short circuit GMAW welding, an increase in inductance will decrease the number of short circuit transfers per
second (provided no other changes are made) and increase the arc-on time. The increased arc-on time makes
the welding puddle more fluid.
MIG
CV weld process with individual settings of voltage and wire speed.
Process
A selection made for MIG, Pulse, Pro-pulse, RMD-Pro, Stick, Carbon Arc, Flux Core (FCAW), and Lift-TIG.
Process Set Up
Selection procedure for entering program.
Program
Eight active slots for selection of various processes, wire types, and parameters.
Program Load
Enters selected program information (process, wire type, gas, etc.) into program slot (1-8).
Pro-pulse
Pulse process utilizing constant current ramps with constant voltage control of peaks and backgrounds.
Adaptive response is controlled by peak and minimum current levels. Benefits are shorter arc lengths, better
puddle control, more tolerant of tip-to-work variation, less audible noise, no arc wandering, allows weld to fill in
at toes increasing travel speed and deposition, and more tolerant to poor fit up and gaps.
Pulse
Conventional pulse program using peak, background, pulse width, frequency, and peak voltage as factory
taught data. Adaptive method is controlled by frequency adjustment.
RMD-Pro
RMD-Pro refers to Regulated Metal Deposition. A precisely controlled short-circuit transfer. Benefits of RMDPro are well suited to root pass welding on pipe, improves gap filling and spatter reduction. Provides less heat
input into workpiece, minimizes distortion and allows use of larger diameter wire on thin gauge materials.
Sharp Arc
In pulse and Pro-pulse mode this adjustment changes the arc cone by adjusting the preprogrammed factory
pulse data. In RMD-Pro this control will affect the arc in much the same way as inductance.
Start
Provides voltage/arc adjust, wire feed rate, and time value for modified arc starts [which is only adjustable with
the optional PDA with PipePro Program Management software (PipeProMgr)].
Stick
Stick (SMAW) welding uses a flux covered consumable electrode that produces a shielding gas and slag to
shield the arc and molten weld puddle.
Synergic
Synergic refers to the unit’s ability to use preprogrammed pulse parameters to determine the actual pulse
settings of Peak Amperage, Background Amperage, Pulse Frequency and Pulse Width at any specific wire feed
speed setting.
TIG
TIG (GTAW) welding uses a nonconsumable tungsten electrode and shielding gas to produce a strong, clean,
high quality weld.
Volts
Preset voltage in MIG mode at idle, actual voltage while welding, and 3 seconds hold value at end of weld.
Wire Type
Selection of wire type by alloys and classification.
WFS
Term used to represent wire feed speed. In MIG mode, wire feed setting is independent of voltage setting. In
pulse, Pro-pulse, and RMD-Pro adjusting wire feed speed also increases power level on wire electrode (one
knob control).

Note: Arc Control is arc width and Arc Adjust/Trim is arc length. Wire feed speed and voltage are synergic for the
RMD and ProPulse processes. Therefore, when adjusting wire feed speed, the voltage is automatically adjusted so it
is not necessary to adjust Arc Adjust/Trim. These are only starting parameters, the operator must make final
adjustments depending on material and conditions.
*See wire manufacturer for recommended wire feed speed and gas mixture.
4-21. Welding Stainless Steel With And Without Backing Gas Using PipePro 450 RFC
When welding stainless steel with or without backing gas, the following guidelines are recommended:
1.
Only use stainless steel wire with a high silicon content as it helps the flow of the weld puddle and the silicon acts as
a de-oxidizer.
2. It is important to have proper joint preparation and fit up. Use a bevel at the pipe joint of 35-37.5 degrees (70-75 degrees inclusive) with a land of a
knife edge to 1/16 in. (1.6 mm) and a minimum gap of 1/8 in. (3.2 mm).
3.
Be sure that any mill scale is remove from inside the pipe joint before welding the root weld. This can be done by grinding the inside of the joint area.
4. Use Tri-H (90% helium/7.5% Argon/2.5% CO2 shielding gas). A 98/2 Argon/ is available, but the Tri-H mixture is the optimal choice for the application.
5.
Always use a down hill technique when welding with the RMD process for the root pass weld.
6.
It is very important to feather tack welds to ensure these are consumed when completing the root pass weld.
7.
Always use a tapered nozzle when welding out the root especially with no backing gas to assist in providing adequate shielding gas coverage.
Following these guidelines should result in successful welding of stainless steel using the PipePro 450 RFC. Contact the nearest factory-authorized
Distributor with any questions about this application.

around the welding circuit and welding equipment. EMF fields may 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:
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.
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.

7-2. Troubleshooting Welding Power Source/Wire Feeder Issues
If the welding power source and wire feeder are NOT responding after everything is connected, follow the items listed below before contacting the
nearest factory-authorized service agent:
Welding power source is plugged in and there is no power after turning on unit.
S
If unit is directly connected to a line disconnect box or plugged into a receptacle from a line disconnect box, be sure that the line disconnect switch
or main breaker is in the ON position.
Wire feeder has no power when turned on.
S
Check if the 72-socket plug is connected to the receptacle on rear of welding power source, and check that the 14-pin plug from the wire feeder is
connected to the matching receptacle on rear of welding power source.
Wire does not feed from wire feeder to end of gun.
S
Check to see if wire diameter matches the groove size of the drive rolls.
S
Check if tension on drive rolls is too loose or too tight.
S
Check if gun liner is the correct size for the wire size.
S
Check if contact tip is correct size for the wire size, and that end of contact tip is not plugged.
S
Check if gun end is fully inserted into wire drive housing at feeder, and knob is tightened down to secure gun end.
Weld is not consistent from one welding application to another.
S
Be sure that ground is connected to a clean, paint-free area of pipe; otherwise, grind an area if necessary to make a good ground connection.
S
Keep ground as close as possible to joint being welded.
S
Check if volt sensing lead is connected to the welding power source and that ground connection is secure. Check for any frayed wires at ground
end of volt sensing lead that may prevent a good connection.
S
Be sure that volt sense lead shielding is not touching center conductor.
S
Be sure that wire feeder control cable and volt sensing lead are separated from weld cables.
S
Be sure gun angle during welding is straight in to 15 degrees back at joint.
S
Follow recommended settings in Operation section of manual to select a starting point for welding.
S
Recommended joint preparation and fit-up is 1/32-1/16 in. (0.8-1.6 mm) land and a 1/8 in. (3.2 mm) root opening.
Porosity in weld bead.
Check shielding gas supply that there is enough gas and supply is turned on.
Check shielding gas flow rate at regulator.
Check that gas pressure to the wire feeder does not exceed 90 psi (621 kPa).
Check all shielding gas fitting and tighten if necessary.
Remove gun end from wire drive housing and check condition of O-rings. Replace any worn or missing O-rings.
Check power pin end of gun and tighten with a wrench.
Be sure that gun end is fully inserted into wire drive housing and knob is tightened down to secure gun end.
Check and clean shielding gas nozzle on gun.
Trouble feeding wire when welding. Check drive rolls and wire guides to make sure they match the wire style and size.
Check drive roll tension and readjust if necessary.
Be sure that gun end is fully inserted into wire drive housing and knob is tightened down to secure gun end.
Check if hub tension at wire spool is too tight or too loose and readjust if necessary.
Be sure that welding gun cable is as straight as possible from wire feeder to workpiece.
Check if contact tip is correct size for the wire size, and that end of contact tip is not plugged.
Check if gun liner is the correct size for the wire size and liner is not dirty or damaged. Clean or replace gun liner if necessary.
Trouble with Program Select when using a DX model wire feeder.
PipePro DX series feeders will automatically select an active program when welding begins. The program selected will match the active program in the
feeder (i.e. if program 5 is selected in the welding power source and program 3 is selected in the DX feeder, when welding begins the power source will
change to program 3).
If programs in the welding power source do not change when changing programs in the DX wire feeder, check the cable connections between the
welding power source and wire feeder. Programs are selected by Remote Program Select A and Remote Program Select B (RPS-A and RPS-B) lines
in the wire feeder cable. RPS-A is a pulse width modulated (PWM) signal that creates an analog signal to select 1 of 4 programs. RPS-B is a digital
signal that select a bank of programs, 1-4 or 5-8.

Ordering Information For PCM, AIM And UIM Circuit Boards
The UIM, AIM and PCM boards must have compatible programs in order to communicate together and provide proper system performance. If the
program has been updated since the system was received, the original program revision may not match the serial number of the PipePro 450 RFC
shown in Table 9-1. In order to provide the correct replacement board, it is necessary to know the program revision for each of the boards in the PipePro
450 RFC.
Follow the procedure to Check Program Revision for each board according to Section 4-22.
The last three numbers of the program and the program revision letter appear on the display. All three boards will match one of the rows horizontally in
Table 9-1. The WFCM board will appear on the display for earlier versions of program. This board is not used in the PipePro 450 RFC so it can be
ignored in this case. Once the board program revisions are identified, use Table 9-1 to select the proper replacement board part number(s).
If the program revision cannot be found due to board failure, the serial number and/or knowledge of a prior update must be used to determine the correct
board number. Another welding power source at the same location may be used to determine the program revision to remain consistent. If using a DX
feeder, the unit must have revision F PCM program or greater for feeder to function correctly.

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 remedies other than as stated herein, and
