Protect yourself and others from injury — read, follow, and save these important safety precautions and operating instructions.
1-1. Symbol Usage
DANGER! − Indicates a hazardous situation which, if
not avoided, will result in death or serious injury. The
possible hazards are shown in the adjoining symbols
or explained in the text.
Indicates a hazardous situation which, if not avoided,
could result in death or serious injury. The possible
hazards are shown in the adjoining symbols or explained in the text.
NOTICE − Indicates statements not related to personal injury.
. Indicates special instructions.
This group of symbols means Warning! Watch Out! ELECTRIC
SHOCK, MOVING PARTS, and HOT PARTS hazards. Consult symbols and related instructions below for necessary actions to avoid the
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-243477 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

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-243477 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.

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.

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-243477 Page 6
chauffement 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-243477 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.

SECTION 4 − SPECIFICATIONS
4-1. Features And Benefits
Auto-Linet Power Management Technology is circuitry that automatically adapts the power source to the primary voltage being applied (see Section 5-8).
LVCt Line Voltage Compensation is circuitry that keeps the power source output constant regardless of input power fluctuation.
Wind Tunnel Technologyt circulates air over components that require cooling, not over electronic circuitry, which reduces contaminants and improves reliability in harsh welding environments.
Fan-On-Demandt cooling system operates only when needed, reducing noise, energy use and the amount of contaminants pulled through the machine.
Thermal Overload Protection automatically shuts down the unit, only when necessary to prevent damage to internal components if the duty cycle
is exceeded or air flow and cooling are restricted (see Section 4-7).
Auto Remote Sense enables the unit to automatically sense the connection of a remote control. Operation of the remote control is dependent on the
Mode Switch Setting (see Section 6-2).
Lift-Arct TIG starts provide a contamination free weld without the use of high frequency in the Lift-Arc TIG Welding Mode (see Section 7-3).
Synergic Pulsed MIG Operation allows single knob control of the arc. As wirefeed speed is increased or decreased, the pulse parameters increase
or decrease matching the power output to the wire speed (see Section 6-3).
4-2. Arc Controls
DIG control allows the arc characteristics, soft versus stiff, to be changed for specific applications and electrodes in CC and Stick Welding Modes
(see Sections 9-2 and 9-3).
Programmable Hot Start allows the start amperage and time to be changed for CC and Stick Welding Modes (see Sections 9-2 and 9-3).
Inductance influences the arc stiffness, bead width and appearance, and puddle fluidity in MIG and V-Sense Feeder Welding Modes (see Sections
8-2 and 8-8).
SharpArct optimizes the size and shape of the arc cone, bead width and appearance, and puddle fluidity in Pulsed MIG Welding Mode (see Section
8-4).
4-3. Serial Number And Rating Label Location
The serial number and rating information for this product is located on the rear panel. Use rating label to determine input power requirements and/or

C. Information On Electromagnetic Compatibility (EMC)
!
This Class A equipment is not intended for use in residential locations where the electrical power is provided by the public low−
voltage supply system. There can be potential difficulties in ensuring electromagnetic compatibility in those locations, due to conducted as well as radiated disturbances.
This equipment complies with IEC61000-3-11 and IEC 61000−3−12 and can be connected to public low-voltage systems provided that the public
low-voltage system impedance Zmax at the point of common coupling is less than 46.39 mW (or the short−circuit power Ssc is greater than
3,449,293 VA). It is the responsibility of the installer or user of the equipment to ensure, by consultation with the distribution network operator if
necessary, that the system impedance complies with the impedance restrictions.

5-7. Electrical Service Guide
Elec Serv 2017-01
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.
NOTICE − Actual input voltage should not be 10% less than minimum and/or 10% more than maximum input voltages listed in table. If actual input
voltage is outside this range, output may not be available.
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.

2 “Time-Delay” fuses are UL class “RK5” . See UL 248.
3 “Normal Operating” (general purpose - no intentional delay) fuses are UL class “K5” (up to and including 60 amps), and UL class “H” ( 65 amps and
above).
4 Conductor data in this section specifies conductor size (excluding flexible cord or cable) between the panelboard and the equipment per NEC Table
310.15(B)(16) and is based on allowable ampacities of insulated copper conductors having a temperature rating of 167°F (75°C) with not more than
three single current−carrying conductors in a raceway. If a flexible cord or cable is used, minimum conductor size may increase. See NEC Table
400.5(A) for flexible cord and cable requirements.

operation or Section 8-4 for Pulsed MIG operation.
Pulsed MIG Manual/Auto Control
This option sets the PULSED MIG control as manual
(PULS MAN) or Auto (PULS AUTO) operation. When
set to manual operation, the arc length setting on power
source and wire speed setting on wire feeder need to
be adjusted independently to achieve the desired arc
length. When set to Auto operation, once arc length is
determined it is not necessary to change the arc length
value with changes in wirefeed speed.
The XMT 350 MPa and synergic feeders allow single
knob control of the arc. As wirefeed speed is increased
or decreased, the pulse parameters increase or decrease matching the power output to the wire speed.
. Auto Operation will only work with synergic wire
feeders. All other wire feeders will only operate as
manual control.
Even when Auto is displayed, operation will be
manual when any other feeder is connected. See
product literature for a list of compatible synergic
feeders.

bead appearance.
. Each Wire and Gas Type combination
has independent Arc Length and SharpArc settings. These settings are preserved when the unit is turned off.
Arc Length - Pulsed MIG Manual Control
(see Section 6-3)
Arc length corresponds to the level of energy needed to burn off the welding electrode.
As wire feed speed increases, a higher arc
length setting is required to burn off the
additional wire. The arc length setting appears in the Left Display when the Arc
Length Indicator is lit. Arc length can be adjusted from 0 to 100.
After the welding output terminals are energized, but prior to arc initiation, the unit displays the letter “R” and a reference wire
speed (IPM) on the Right Display. The reference wire speed can be used as a starting point for the wire speed setting at the
feeder. The wire speed and arc length setting can then be further adjusted to achieve
the desired arc length.
The Configuration Option Menu (see Section 6-1) can be used to change the arc
length setting (0 to 100) to average arc voltage. Average arc voltage can be used as an
alternative method to set the Pulsed MIG
welding arc with the same parameters
(voltage and wire speed) as a conventional
MIG arc. Lower voltage settings correspond to tighter arc lengths while higher
voltage settings correspond to longer arc
lengths. If the voltage mode is selected, the
average voltage preset will be displayed on
the Left Display with the Volts Indicator lit.
Arc Length - Pulsed MIG Auto Control
(see Section 6-3)
In Auto operation the arc length setting is
0-100. The programs have been developed
at 50 arc length setting. Increasing or decreasing the arc length setting from 50 will
change the arc length. It is not necessary to
change the arc length value when changing
wire feed speed settings.

bead appearance.
. Each Wire and Gas Type combination
has independent Arc Length and SharpArc settings. These settings are preserved when the unit is turned off.
Arc Length
Arc length corresponds to the level of energy needed to burn off the welding electrode.
As wire feed speed increases, a higher arc
length setting is required to burn off the
additional wire. The arc length setting appears in the Left Display when the Arc
Length Indicator is lit. Arc length can be adjusted from 0 to 100.
Prior to arc initiation, the unit displays the
letter “R” and a reference wire speed (IPM)
on the Right Display. The reference wire
speed can be used as a starting point for
the wire speed setting at the feeder. The
wire speed and arc length can then be further adjusted to achieve the desired arc
length.
The Configuration Option Menu (see Section 6-3) can be used to change the Arc
Length setting from 0 to 100 to average arc
voltage. Average arc voltage can be used
as an alternative method to set the Pulsed
