SECTION 1 - SAFETYPRECAUTIONS - READ BEFORE USING
WARNING
- 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.
- 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.
- Only qualified persons should install, operate, maintain, and
repair this unit.
- During operation, keep everybody, especially children, away.
ARC WELDING can be hazardous.
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 equiment is a hazard.
1.- Do not touch live electrical parts.
2.- Wear dry, hole-free insulating gloves and body protection.
3.- Insulate yourself from work and ground using dry insulating
mats or covers.
4.- Disconnect input power or stop engine before installing or
servicing this equipment.
5.- Properly install and ground this equipment according to this
Owner's Manual and national, state, and local codes.
6.- Turn off all equipment when not in use.
7.- Do not use worn, damaged, undersized, or poorly spliced cables.
8.- Do not wrap cables around your body.
9.- Ground the workpiece to a good electrical (earth) ground.
10.- Do not touch electrode while in contact with the work (ground)
circuit.
11.- Use only well-maintained equipment. Repair or replace damaged
parts at once.
12.- Wear a safety harness to prevent falling if working above floor
level.
13.- Keep all panels and cover securely in place.
ARC RAYS can burn eyes and skin;
NOISE can damage hearing.
Arc rays from the welding process produce intense
heat and strong ultraviolet rays that can burn eyes and
skin. Noise from some processes can damage hearing.
1.- Wear a welding helmet fitted with a proper shade
of filter (see ANSIZ49.1 listed in Safety Standards) to protect
FUMES AND GASES can be hazardous
to your health.
Welding produces fumes and gases. Breathing these
fumes and gases can be hazardous to your health.
1.- Keep your head out of the fumes. Do not breath the fumes.
2.- If inside, ventilate the area and / or use forced ventilation at the arc
to remove welding fumes and gases.
3.- If ventilation is poor, use an approved air-supplied respirator.
4.- Read the Material Safety Data Sheets (MSDSs) and the
manufacturer´s instruction for metal, consumables, coatings, and
cleaners.
5.- Work in a confined space only if it is well ventilated, or while wearing
an air-supplied respirator. Shielding gases used for welding can
displace air causing injury or death. Be sure the breathing air is safe.
6.- 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.
7.- 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 if necessary, while wearing an air-
supplied respirator. The coatings and any metals containing these
elements can give off toxic fumes if welded.
FLYING SPARK AND HOT METAL can
cause injury
Chipping and grinding cause flying metal . As welds
cool, they can throw off slag.
1.- Wear approved face shield or safety goggles. Side shields
recommended.
2.- Wear proper body protection to protect skin.
your face and eyes when welding or watching.
2.- Wear approved safety glasses. Side shields recommended.
3.- Use protective screens or barriers to protect others from flash and
glade; warn others not to watch the arc.
4.- Wear protective clothing made from durable, flame- resistant mate
rial (wool and leather) and foot protection.
5.- Use approved ear plugs or ear muffs if noise level is high.
i

CYLINDERS can explode if damaged.
Shieldinggas 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.
1.- Protect compressed gas cylinders from excessive heat, mechanical
shocks, and arcs.
2.- Install and secure cylinders in an upright position by chaining them
to a stationary support or equipment cylinder rack to prevent falling
or tipping.
3.- Keep cylinders away from any welding or other electrical circuits.
4.- Never allow a welding electrode to touch any cylinder.
5.- Use only correct shielding gas cylinders, regulators, hoses, and
fittings designed for the specific application; maintain them and
associated parts in good condition.
6.- Turn face away from valve outlet when opening cylinder valve.
7.- Keep protective cap in place over valve except when cylinder is in
use or connected for use.
8.- Read and followinstructions on compressed gas cylinders, associated
equipment, and CGA publication P-1 listed in Safety Standards.
ENGINES can be hazardous.
WARNING
ENGINE EXHAUST GASES can kill.
Engines produce harmful exhaust gases.
1.- Use equipment outside in open, well-ventilated
areas.
2.- If used in a closed area, vent engine exhaust outside and away from
any building air intakes.
ENGINE FUEL can cause fire or
explosion.
Engine fuel is highly flammable.
1.- Stop engine before checking or adding fuel.
2.- Do not add fuel while smoking or if unit is near any sparks or open
flames.
3.- Allow engine to cool before fueling. If possible, check and add fuel
to cold engine before beginning job.
4.- Do not overfill tank - allow room for fuel to expand.
5.- Do not spill fuel. If fuel is spilled, clean up before starting engine.
MOVING PARTS can cause injury.
Moving parts, such as fans, rotors, and belts can cut
fingers and hands and catch loose clothing.
1.- Keep all doors, panels, covers, and guards closed
and securely in place.
2.- Stop engine before installing or connecting unit.
3.- Have only qualified people remove guards or covers for maintenance
and troubleshooting as necessary.
4.- To prevent accidental stating during servicing, disconnect negative
(-) battery cable from battery.
5.- Keep hands, hair, loose clothing, and tools away from moving parts.
6.- Reinstall panels or guards and close doors when servicing is finished
and before starting engine.
SPARKS can cause BATTERY GA-
SES TO EXPLODE; BATTERY ACID
can burn eyes and skin.
Batteries contain acid and generate explosive gases.
1.- Always wear a face shield when working on a
battery.
2.- Stop engine before disconnecting or connecting battery cables.
3.- Do not allow tools to cause sparks when working on a battery.
4.- Do not use welder to charge batteries or jump start vehicles.
5.- Observe correct polarity (+ and -) on batteries.
WELDING can cause fire or explosion.
Sparks and spatter fly off from the welding arc. The
flying sparks and hot metal, weld spatter, hot workpiece,
and hot equipment can cause fires and burns. Acciden-
tal contact of electrode or welding wire to metal objects
can cause sparks, overheating, or fire.
1.- Protect yourself and others from flying sparks and hot metal.
2.- Do not weld where flying sparks can strike flammable material.
3.- Remove all flammables within 35ft (10.7 m) of the welding arc. If
this is not possible, tightly cover them with approved covers.
4.- Be alert that welding sparks and hot materials from welding can
easily go through small cracks and openings to adjacent areas.
5.- Watch for fire, and keep a fire extinguisher nearby.
6.- Be aware that welding on a ceiling, floor, bulkhead, or partition can
cause fire on the hidden side.
7.- Do not weld on closed containers surch as tanks or drums.
8.- Connect work cable to the work as close to the welding areas as
practical to prevent welding current from traveling long, possibly
unknown paths and causing electric shock and fire hazards.
9.- Do not use welder to thaw frozen pipes.
10.- Remove stick electrode from holder or cut off welding wire at
contact tip when not in use.
11.- Wear oil-free protective garments such as leather gloves, heavy
shirt, cuffless trousers, high shoes, and a cap.
ii

STEAM AND PRESSURIZED HOT
COOLANT can burn face, eyes, and
skin.
The coolant in the radiator can be very hot and under
pressure.
1.- Do not remove radiator cap when engine is hot. Allow engine to cool.
2.- Wear gloves and put a rag over cap area when removing cap.
3.- Allow pressure to escape before completely removing cap.
- Additional Symbols For Installation, Operation, And Maintenance
NOISE can damage hearing.
Noise from some processes or equipment can damage hearing.
- Wear approved ear protection if noise level is high.
FALLING EQUIPMENT can injure
