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.
When making input connections, attach proper grounding conductor first − double-check connections.
Keep cords dry, free of oil and grease, and protected from hot metal
and sparks.
Frequently inspect input power cord and ground conductor for
damage or bare wiring – replace immediately if damaged – bare
wiring can kill.
Turn off all equipment when not in use.
Do not use worn, damaged, undersized, or repaired cables.
Do not drape cables over your body.
If earth grounding of the workpiece is required, ground it directly
with a separate cable.
Do not touch electrode if you are in contact with the work, ground,
or another electrode from a different machine.
Do not touch electrode holders connected to two welding machines at the same time since double open-circuit voltage will be
present.
Use only well-maintained equipment. Repair or replace damaged
parts at once. Maintain unit according to manual.
Wear a safety harness if working above floor level.
Keep all panels and covers securely in place.
Clamp work cable with good metal-to-metal contact to workpiece
or worktable as near the weld as practical.
Insulate work clamp when not connected to workpiece to prevent
contact with any metal object.
Do not connect more than one electrode or work cable to any
single weld output terminal. Disconnect cable for process not in
use.
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-265 363 Page 1
FUMES AND GASES can be hazardous.
Welding produces fumes and gases. Breathing
these fumes and gases can be hazardous to your
health.
D Keep your head out of the fumes. Do not breathe the fumes.
D If inside, ventilate the area and/or use local forced ventilation at the
arc to remove welding fumes and gases. The recommended way
to determine adequate ventilation is to sample for the composition
and quantity of fumes and gases to which personnel are exposed.
D If ventilation is poor, wear an approved air-supplied respirator.
D Read and understand the Safety Data Sheets (SDSs) and the
manufacturer’s instructions for adhesives, coatings, cleaners,
consumables, coolants, degreasers, fluxes, and metals.
D Work in a confined space only if it is well ventilated, or while
wearing an air-supplied respirator. Always have a trained watchperson nearby. Welding fumes and gases can displace air and
lower the oxygen level causing injury or death. Be sure the breathing air is safe.
D Do not weld in locations near degreasing, cleaning, or spraying operations. The heat and rays of the arc can react with vapors to form
highly toxic and irritating gases.
D Do not weld on coated metals, such as galvanized, lead, or
cadmium plated steel, unless the coating is removed from the weld
area, the area is well ventilated, and while wearing an air-supplied
respirator. The coatings and any metals containing these elements
can give off toxic fumes if welded.
ARC RAYS can burn eyes and skin.
Arc rays from the welding process produce intense
visible and invisible (ultraviolet and infrared) rays
that can burn eyes and skin. Sparks fly off from the
weld.
D Wear an approved welding helmet fitted with a proper shade of
filter lenses to protect your face and eyes from arc rays and
sparks when welding or watching (see ANSI Z49.1 and Z87.1
listed in Safety Standards).
D Wear approved safety glasses with side shields under your
helmet.
D Use protective screens or barriers to protect others from flash,
glare and sparks; warn others not to watch the arc.
D Wear body protection made from durable, flame−resistant material (leather, heavy cotton, wool). Body protection includes
oil-free clothing such as leather gloves, heavy shirt, cuffless
trousers, high shoes, and a cap.
WELDING can cause fire or explosion.
Welding on closed containers, such as tanks,
drums, or pipes, can cause them to blow up. Sparks
can fly off from the welding arc. The flying sparks, hot
workpiece, and hot equipment can cause fires and
burns. Accidental contact of electrode to metal objects can cause
sparks, explosion, overheating, or fire. Check and be sure the area is
safe before doing any welding.
D Remove all flammables within 35 ft (10.7 m) of the welding arc. If
this is not possible, tightly cover them with approved covers.
D Do not weld where flying sparks can strike flammable material.
D Protect yourself and others from flying sparks and hot metal.
D Be alert that welding sparks and hot materials from welding can
easily go through small cracks and openings to adjacent areas.
D Watch for fire, and keep a fire extinguisher nearby.
D Be aware that welding on a ceiling, floor, bulkhead, or partition can
cause fire on the hidden side.
D Do not weld on containers that have held combustibles, or on
closed containers such as tanks, drums, or pipes unless they are
properly prepared according to AWS F4.1 and AWS A6.0 (see
Safety Standards).
D Do not weld where the atmosphere 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
hazards.
D Do not use welder to thaw frozen pipes.
OM-265 363 Page 2
D Remove stick electrode from holder or cut off welding wire at
contact tip when not in use.
D Wear body protection made from durable, flame−resistant material
(leather, heavy cotton, wool). Body protection includes oil-free
clothing such as leather gloves, heavy shirt, cuffless trousers, high
shoes, and a cap.
D Remove any combustibles, such as a butane lighter or matches,
from your person before doing any welding.
D After completion of work, inspect area to ensure it is free of sparks,
glowing embers, and flames.
D Use only correct fuses or circuit breakers. Do not oversize or bypass them.
D Follow requirements in OSHA 1910.252 (a) (2) (iv) and NFPA 51B
for hot work and have a fire watcher and extinguisher nearby.
D Read and understand the Safety Data Sheets (SDSs) and the
manufacturer s instructions for adhesives, coatings, cleaners,
consumables, coolants, degreasers, fluxes, and metals.
FLYING METAL or DIRT can injure eyes.
D Welding, chipping, wire brushing, and grinding
cause sparks and flying metal. As welds cool,
they can throw off slag.
D Wear approved safety glasses with side
shields even under your welding helmet.
BUILDUP OF GAS can injure or kill.
D Shut off compressed gas supply when not in use.
D Always ventilate confined spaces or use
approved air-supplied respirator.
ELECTRIC AND MAGNETIC FIELDS (EMF)
can affect Implanted Medical Devices.
D Wearers of Pacemakers and other Implanted
Medical Devices should keep away.
D Implanted Medical Device wearers should consult their doctor
and the device manufacturer before going near arc welding, spot
welding, gouging, plasma arc cutting, or induction heating
operations.
NOISE can damage hearing.
Noise from some processes or equipment can
damage hearing.
D Wear approved ear protection if noise level is high.
CYLINDERS can explode if damaged.
Compressed gas cylinders contain gas under high
pressure. If damaged, a cylinder can explode. Since
gas cylinders are normally part of the welding
process, be sure to treat them carefully.
D Protect compressed gas cylinders from excessive heat, mechanical shocks, physical damage, slag, open flames, sparks, and arcs.
D Install cylinders in an upright position by securing to a stationary
support or cylinder rack to prevent falling or tipping.
D Keep cylinders away from any welding or other electrical circuits.
D Never drape a welding torch over a gas cylinder.
D Never allow a welding electrode to touch any cylinder.
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 right equipment, correct procedures, and sufficient number of persons to lift and move 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 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-265 363 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.

inhalation peut être dangereux pour votre santé.
D Eloigner votre tête des fumées. Ne pas respirer les fumées.
D À l’intérieur, ventiler la zone et/ou utiliser une ventilation forcée au
niveau de l’arc pour l’évacuation des fumées et des gaz de
soudage. Pour déterminer la bonne ventilation, il est recommandé
de procéder à un prélèvement pour la composition et la quantité
de fumées et de gaz auxquels est exposé le personnel.
D Si la ventilation est médiocre, porter un respirateur anti-vapeurs
approuvé.
D Lire et comprendre les fiches de données de sécurité et les instructions du fabricant concernant les adhésifs, les revêtements, les
nettoyants, les consommables, les produits de refroidissement, les
dégraisseurs, les flux et les métaux.
D Travailler dans un espace fermé seulement s’il est bien ventilé ou
en portant un respirateur à alimentation d’air. Demander toujours à
un surveillant dûment formé de se tenir à proximité. Des fumées et
des gaz de soudage peuvent déplacer l’air et abaisser le niveau
d’oxygène provoquant des blessures ou des accidents mortels.
S’assurer que l’air de respiration ne présente aucun danger.
D Ne pas souder dans des endroits situés à proximité d’opérations
de dégraissage, de nettoyage ou de pulvérisation. La chaleur et
les rayons de l’arc peuvent réagir en présence de vapeurs et former des gaz hautement toxiques et irritants.
D Ne pas souder des métaux munis d’un revêtement, tels que l’acier
galvanisé, plaqué en plomb ou au cadmium à moins que le revêtement n’ait été enlevé dans la zone de soudure, que l’endroit soit
bien ventilé, et en portant un respirateur à alimentation d’air. Les
revêtements et tous les métaux renfermant ces éléments peuvent
dégager des fumées toxiques en cas de soudage.
LES RAYONS DE L’ARC peuvent
provoquer des brûlures dans les
yeux et sur la peau.
Le rayonnement de l’arc du procédé de soudage
génère des rayons visibles et invisibles intenses
(ultraviolets et 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).

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 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:
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.
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.

Example Power Source Operation Using A PLC
To enable welding control from the Automation Interface, set the “Automation Enable” bit (0x4000) in the Command Flags register
(MODBUS Holding Register 101).
Set desired Weld Mode by writing MODBUS Holding Register 105 using look-up table Table 8-6.
Obtain Minimum and Maximum values by reading from Input Registers section 300 (See Table 8-8).
Set all relevant parameters (MODBUS Holding Registers 102-107) to their desired values. They must be within the minimum and maximum
values read in Step 2. Verify the values are correct by reading Input Registers 102-107.
Enable weld output by setting the Output Enable Flag to 1 in the Command Flags register (MODBUS Holding Register 101).
Voltage & Current Feedback values can be read from Input Registers section 200 (See Table 8-8).
Disable weld output by clearing the Output Enable Flag to 0 in the Command Flags register (MODBUS Holding Register 101).
If there is no communication from the MODBUS master for a period greater than one second, the power source will reset all registers to
their default value. Communication can consist of reading or writing.
