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.
DDo not touch live electrical parts.
DWear dry, hole-free insulating gloves and body protection.
DInsulate yourself from work and ground using dry insulating mats
or covers big enough to prevent any physical contact with the work
or ground.
DDo not use AC output in damp areas, if movement is confined, or if
there is a danger of falling.
DUse AC output ONLY if required for the welding process.
DIf AC output is required, use remote output control if present on
unit.
DAdditional 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 unavoid-
able or accidental contact with the workpiece or ground. For these
conditions, use the following equipment in order presented: 1) a
semiautomaticDC constant voltage (wire) welder, 2) a DC manual
(stick) welder, or 3) an AC welder with reduced open-circuit volt-
age. In most situations, use of a DC, constant voltage wire welder
is recommended. And, do not work alone!
DDisconnect 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).
DProperly install and ground this equipment according to its
Owner’s Manual and national, state, and local codes.
DAlways 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.
DWhen making input connections, attach proper grounding conduc-
tor first −double-check connections.
DKeep cords dry, free of oil and grease, and protected from hot metal
and sparks.
DFrequently inspect input power cord for damage or bare wiring −
replace cord immediately if damaged −bare wiring can kill.
DTurn off all equipment when not in use.
DDo not use worn, damaged, undersized, or poorly spliced cables.
DDo not drape cables over your body.
DIf earth grounding of the workpiece is required, ground it directly
with a separate cable.
DDo not touch electrode if you are in contact with the work, ground,
or another electrode from a different machine.
DDo not touch electrode holders connected to two welding ma-
chines at the same time since double open-circuit voltage will be
present.
DUse only well-maintained equipment. Repair or replace damaged
parts at once. Maintain unit according to manual.
DWear a safety harness if working above floor level.
DKeep all panels and covers securely in place.
DClamp work cable with good metal-to-metal contact to workpiece
or worktable as near the weld as practical.
DInsulate work clamp when not connected to workpiece to prevent
contact with any metal object.
DDo not connect more than one electrode or work cable to any
single weld output terminal.
SIGNIFICANT DC VOLTAGE exists in inverter weld-
ing power sources AFTER removal of inputpower.
DTurn Off inverter, disconnect input power, and discharge input
capacitors according to instructions in Maintenance Section
before touching any parts.
HOT PARTS can burn.
DDo not touch hot parts bare handed.
DAllow cooling period before working on equip-
ment.
DTo handle hot parts, use proper tools and/or
wear heavy, insulated welding gloves and
clothing to prevent burns.
Welding produces fumes and gases. Breathing
these fumes and gases can be hazardous to your
health.
FUMES AND GASES can be hazardous.

OM-246 022 Page 2
DKeep your head out of the fumes. Do not breathe the fumes.
DIf inside, ventilate the area and/or use local forced ventilation at the
arc to remove welding fumes and gases.
DIf ventilation is poor, wear an approved air-supplied respirator.
DRead and understand the Material Safety Data Sheets (MSDSs)
and the manufacturer’s instructions for metals, consumables,
coatings, cleaners, and degreasers.
DWork in a confined space only if it is well ventilated, or while
wearing an air-supplied respirator. Always have a trained watch-
person nearby. Welding fumes and gases can displace air and
lower the oxygen level causing injury or death. Be sure the breath-
ing air is safe.
DDo 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.
DDo 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 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.
DWear 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).
DWear approved safety glasses with side shields under your
helmet.
DUse protective screens or barriers to protect others from flash,
glare and sparks; warn others not to watch the arc.
DWear protective clothing made from durable, flame-resistant
material (leather, heavy cotton, or wool) and foot protection.
ARC RAYS can burn eyes and skin.
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.
WELDING can cause fire or explosion.
DRemove all flammables within 35 ft (10.7 m) of the welding arc. If
this is not possible, tightly cover them with approved covers.
DDo not weld where flying sparks can strike flammable material.
DProtect yourself and others from flying sparks and hot metal.
DBe alert that welding sparks and hot materials from welding can
easily go through small cracks and openings to adjacent areas.
DWatch for fire, and keep a fire extinguisher nearby.
DBe aware that welding on a ceiling, floor, bulkhead, or partition can
cause fire on the hidden side.
DDo not weld on closed containers such as tanks, drums, or pipes,
unless they are properly prepared according to AWS F4.1 (see
Safety Standards).
DDo not weld where the atmosphere may contain flammable dust,
gas, or liquid vapors (such as gasoline).
DConnect 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.
DDo not use welder to thaw frozen pipes.
DRemove stick electrode from holder or cut off welding wire at
contact tip when not in use.
DWear oil-free protective garments such as leather gloves, heavy
shirt, cuffless trousers, high shoes, and a cap.
DRemove any combustibles, such as a butane lighter or matches,
from your person before doing any welding.
DAfter completion of work, inspect area to ensure it is free of sparks,
glowing embers, and flames.
DUse only correct fuses or circuit breakers. Do not oversize or by-
pass them.
DFollow requirements in OSHA 1910.252 (a) (2) (iv) and NFPA 51B
for hot work and have a fire watcher and extinguisher nearby.
FLYING METAL or DIRT can injure eyes.
DWelding, chipping, wire brushing, and grinding
cause sparks and flying metal. As welds cool,
they can throw off slag.
DWear approved safety glasses with side
shields even under your welding helmet.
BUILDUP OF GAS can injure or kill.
DShut off shielding gas supply when not in use.
DAlways ventilate confined spaces or use
approved air-supplied respirator.
ELECTRIC AND MAGNETIC FIELDS (EMF
)
can affect ImplantedMedical Devices.
DWearers of Pacemakers and other Implanted
Medical Devices should keep away.
DImplanted 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.
DWear approved ear protection if noise level is
high.
Shielding 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.
CYLINDERS can explode if damaged.
DProtect compressed gas cylinders from excessive heat, mechani-
cal shocks, physical damage, slag, open flames, sparks, and arcs.
DInstall cylinders in an upright position by securing to a stationary
support or cylinder rack to prevent falling or tipping.
DKeep cylinders away from any welding or other electrical circuits.
DNever drape a welding torch over a gas cylinder.
DNever allow a welding electrode to touch any cylinder.
DNever weld on a pressurized cylinder −explosion will result.
DUse only correct shielding gas cylinders, regulators, hoses, and fit-
tings designed for the specific application; maintain them and
associated parts in good condition.
DTurn face away from valve outlet when opening cylinder valve.
DKeep protective cap in place over valve except when cylinder is in
use or connected for use.

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 inter-
fere with some medical implants, e.g. pacemakers. Protective
measures for persons wearing medical implants have to be taken. For
example, access restrictions for passers−by or individual risk assess-
ment 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 recom-
mended.

3-5.Introduction
A wireless system consists of a transmitter and a re-
ceiver.
1 Foot Pedal Transmitter
2 Hand Control Transmitter
3 Receiver
The foot pedal, hand control, and receiver are cap-
able of remotely turning on the output contactor and
adjusting the output level of a welding power source.
The hand control is equipped with a digital display
capable of providing three parameters: percentage
of available output (default), amperage, and voltage.
Amperage and voltage can only be displayed if weld-
ing power source has amperage and voltage feed-
back available at the Remote 14 receptacle, and is
only viewable while welding, or when feedback is
present. The display is for reference only.
Each foot pedal transmitter and hand control
transmitter has a unique address
The receiver stores the address in permanent
memory
The receiver can only receive information from a
single transmitter
A transmitter can only communicate with a single
receiver.
The receiver can learn a new foot pedal or hand
control address (see sections 3-12 or 3-13 in this
manual for programming instructions).
.Programming is only required for devices pur-
chased separately. The transmitter and receiver
are programmed when purchased as a system/
pair.
