2.- SAFETY PRECAUTIONS
READ INSTRUCTIONS.
• Read Owner's Manual before using or servic-ing unit.
• Use only genuine replacement parts from themanufacturer.
SYMBOL USAGE
DANGER! - Indicates a hazardous situation
which, ifnot avoided, will result in death or
serious injury. Thepossible hazards are shown
in the adjoining symbolsor explained in the text.

ARC WELDING HAZARDS
Only qualified persons should install, operate,
maintain, andrepair this unit.
During operation, keep everybody, especially
children, away.
ELECTRIC SHOCK can kill.
Touching live electrical parts can cause fatal shocksor
severe burns. The electrode and work circuit iselectrically
live whenever the output is on. The inputpower circuit
and machine internal circuits are alsolive when power is
on. In semiautomatic or automatic wire welding, thewire,
wire reel, drive roll housing, and all metal parts touching
thewelding wire are electrically live. Incorrectly installed or
improperlygrounded equipment is a hazard.
• Do not touch live electrical parts.
• Wear dry, hole-free insulating gloves and body protection.
• Insulate yourself from work and ground using dry insulating
matsor covers big enough to prevent any physical contact
with the workor ground.
• Do not use AC output in damp areas, if movement is
confined, or if there is a danger of falling.
• Use AC output ONLYif required for the welding process.
• If AC output is required, use remote output control if present
onunit.
• Additional safety precautions are required when any of
the follow-ing electrically hazardous conditions are present:
in damplocations or while wearing wet clothing; on metal
structures suchas floors, gratings, or scaffolds; when in
cramped positions suchas sitting, kneeling, or lying; or when
there is a high risk of unavoid-able or accidental contact with
the workpiece or ground.
• Disconnect input power or stop engine before installing
orservicing this equipment.
• Properly install and ground this equipment according to
itsOwner's Manual and national, state, and local codes
• Always verify the supply ground - check and be sure that
inputpower cord ground wire is properly connected to ground
terminal indisconnect box or that cord plug is connected to a
properlygrounded receptacle outlet.
• When making input connections, attach proper grounding
conduc-tor first - double-check connections.
• Keep cords dry, free of oil and grease, and protected from
hot metaland sparks.
• Frequently inspect input power cord for damage or bare
wiring - replace cord immediately if damaged - bare wiring
can kill. Turn off all equipment when not in use.
• Do not use worn, damaged, undersized, or poorly spliced
cables.
• Do not drape cables over your body.If earth grounding of
the workpiece is required, ground it directlywith 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 bepresent.
• Use only well-maintained equipment. Repair or replace
damagedparts at once. Maintain unit according to manual.
• Wear a safety harness if working above floor level.
• Keep all panels and covers securely in place.
• Keep all panels and covers securely in place.
• Clamp work cable with good metal-to-metal contact to
workpieceor worktable as near the weld as practical.
• Insulate work clamp when not connected to workpiece to
preventcontact with any metal object.
• Do not connect more than one electrode or work cable to
anysingle weld output terminal.
HOT PARTS can cause severe burns.
• Do not touch hot parts bare handed.
• Allow cooling period before working on gun ortorch.
• To handle hot parts, use proper tools and/orwear heavy,
insulated welding gloves andclothing to prevent burns.
FUMES AND GASES can be hazardous.
Welding produces fumes and gases. Breathingthese fumes
and gases can be hazardous to yourhealth.
• Keep your head out of the fumes. Do not breathe the fumes.
• If inside, ventilate the area and/or use local forced ventilation
at thearc to remove welding fumes and gases.
• If ventilation is poor, wear an approved air-supplied
respirator.
• Read and understand the Material Safety Data Sheets
(MSDSs)and the manufacturer's instructions for metals,
consumables,coatings, cleaners, and degreasers.
• Work in a confined space only if it is well ventilated, or
whilewearing an airsupplied respirator. Always have a
trained watch person nearby. Welding fumes and gases
can displace air andlower the oxygen level causing injury or
death. Be sure the breath-ing air is safe.
• Do not weld in locations near degreasing, cleaning, or
spraying operations. The heat and rays of the arc can react
with vapors to formhighly toxic and irritating gases.
• Do not weld on coated metals, such as galvanized, lead,
orcadmium plated steel, unless the coating is removed from
the weldarea, the area is well ventilated, and while wearing
an airsuppliedrespirator. The coatings and any metals
containing these elementscan give off toxic fumes if welded.
ARC RAYS can burn eyes and skin.
Arc rays from the welding process produce intensevisible
and invisible (ultraviolet and infrared) raysthat can burn eyes
and skin.
• Wear an approved welding helmet fitted with a proper
shade of filter lenses to protect your face and eyes when
welding or watching see ANSI Z49.1, Z87.1, EN175, EN379
listed in Safety Standards
• Wear approved safety glasses with side shields under your
helmet.
• Use protective screens or barriers to protect others from
flash,glare and sparks; warn others not to watch the arc.
