1. GENERAL INFORMATION

GASES AND FUMES

1.01 Notes, Cautions and Warnings

Gases and fumes produced during the Arc

welding/cutting process can be dangerous and

hazardous to your healt.

Throughout this manual,notes,cautions,and

warnings are used to highlight important

information. These highlights are categorized as

follows:

• Keep all fumes and gases from the breathing

area. Keep your head out of the welding fume

plume.

NOTE

• Use an air-supplied respirator if ventilation is

not adeguate to remove all fumes and gases.

An operation, procedure, or background

information wich requires additional emphasis or

is helpful in efficent operation of the system

• The kinds of fumes and gases from the arc

welding/cutting depend on the kind of metal

being used coatings on the metal, and the

different process. You must be very careful

when cutting or welding any metals which may

contain one or more of the following:

CAUTION

A procedure which, if not properly followed, may

cause damage to the equipment.

Antimony Chromium Mercury

Arsenic Cobalt Nickel

Barium Copper Selenium

Beryllium Lead Silver

Cadmium Manganese

WARNING

A procedure which, if not properly followed, may

cause injury to the operator or others in the

operating area.

• Always read the Material Safety data Sheets

(MSDS) that should be supplied with the

material you are using. These MSDS will give

you the information regarding the kind and

amount of fumes and gases that may dangerous

to your healt.

1.02 Important Safety Precautions

• For information on how to test for fumes and

gases in your workplace, refer to item 1 in

Subsection 1.03, Publication in this manual.

WARNING

• Use special equipment, such as water or down

draft welding/cutting tables, to capture fumes

and gases.

OPERATION AND MAINTENANCE OF

WELDING EQUIPMENT CAN BE DANGEROUS

AND HAZARDOUS TO YOUR HEALT.

• Do not use the welding torch in an area where

combustible or explosive gases or materials

are located.

To prevent possible injury, read, understand, and

follow all warnings, safety precautions and

instructions bedore using the equipment. Call 1-

603-298-5711 or your local distributor if you have

any questions.

• Phosgene, a toxic gas, is generated from the

vapors of chlorinated solvents and cleansers.

Remove all sources of these vapors.

GENERAL INFORMATION

ELECTRIC SHOCK

Electric Shock can injure or kill. The arc welding

process uses and produces high voltage electrical

energy. This electric energy can cause severe or

fatal shock to the operator or others in the

workplace

• Never touch any parts that are electrically

“live” or “hot”.

• Wear dry gloves and clothing. Insulate

yourself from the work piece or other parts of

the welding circuit.

• Repair or replace all worn ar damage parts.

• Extra care must be taken when the workplace

is moist or damp.

• Install and mantain equipment according to

NEC code, refer to item 4 in Subsection 1.03,

Publications.

• Disconnect power source before performing

any service or repairs.

• Read and follow all the instruction in the

Operating Manual.

FIRE AND EXPLOSION

Fire and explosion can be caused by hot slag,

sparks or the arc weld.

• Be sure there is no combustible or flammable

material in the workplace. Any material that

cannot be removed must be protected.

• Ventilate all flammable or explosive vapors

from the workplace.

• Do not cut or weld on containers that may

have held combustibles.

• Provide a fire watch when working in an area

where fire hazards may exist.

• Hydrogen gas may be formed and trapped

under aluminium workpieces when they

are cut underwater or while using a water

table. DO NOT cut aluminium alloys

underwater or on a water table unless the

hydrogen gas can be eliminated or

dissipated. Trapped hydrogen gas that is

ignited will cause an explosion.

NOISE

Noise can cause permanent hearing loss. Arc

welding/cutting processes can cause noise levels

to exceed safe limits. You must protect your ears

from loud noise to prevent permanent loss of

hering.

• To protect your hearing from loud noise wear

protective ear plugs and/or ear muffs. Protect

others in the workplace.

• Noise levels should be measured to be sure the

decibels (sound) do not exceed safe levels.

•

For information on how to test for noise,

see item 1 in Subsection 1.03, Publications,

in this manual.

ARC WELDING RAYS

Arc Welding/Cutting Rays can injure your

eyes and burn your skin. The arc welding

cutting process produces very bright ultra

violet and infra red light. These arc rays will

damage your eyes and burn your skin if you

are not properly protected.

•

To protect your eyes, always wear a welding

helmet or shield. Also always wear safety

glasses with side shields goggles or other

protective eye wear.

• Wear welding gloves and suitable clothing to

protect your skin from the arc rays and sparks

GENERAL INFORMATION

Keep helmet and safety glasses in good condition.

replace lenses when cracked, chipped or dirty.

• Protect others in the work area from the arc

rays. Use protective booths, screens or shields.

• Use the shade of lens as raccomanded in

Subsection 1.03, item 4.

BRUIT

Le bruit peut provoquer une perte permanente de

l’ouie. Les procédés de soudage à l’arc de plasma

peuvent provoquer des niveaux sonores

supérieures aux limites normalement acceptables.

Vous dùvez vous protéger les oreilles contre les

bruits forts afin d’éviter une perte permanente de

l’ouïe.

• Pour protéger votre ouïe contre les bruits forts,

portez des taòpons protecteurs st/ou des

protections auriculaires. Protégez également

les autres personnes se trouvant sur le lieu de

travail.

• Il faut measurer les niveaux sonores afin

d’assurer que les décibels (le bruit) ne

dépassent pas les niveaux sûrs.

• Pour des renseignements sur la manière de

tester le bruit, consultez l’article 1, page 5.

DESCRIPTION

The Thermal Arc TA-8/300-KAT is Diesel

engine driven DC welding generator with

selectable Constant Current (CC) and

Constant Voltage (CV) output characteristics.

This unit is designed for use with Shielded

Metal Arc Welding (SMAW), Gas Metal Arc

Welding (GMAW).

NOTE

Volt-Ampere curves show the voltage and

amperage output capabilities of the welding

power source. Curves of other settings will

fall between the curves shown.

DUTY CYCLE

The duty cycle of a welding generator is the

percentage of a ten minute period that welding

generator can be operated at a given output

without causing overheating and damaging og

the unit. This unit is rated at 60 percent duty

cycle when operated at 300 amperes. The unit

can be operated at 300 amperes for six

consecutives minutes, but it must operate at

no load for the remaining four minutes to

allow proper cooling. If the welding amperes

decrease, the duty cycle increases. If the

welding amperes are increased beyond rated

output, the duty cycle will decrease.

CAUTION

EXCEEDING DUTY CYCLE RATINGS

will cause the thermal overload protection

circuit to become energized and shut down

output until the cools to normal operating

temperature.

CAUTION

CONTINUAL EXCEEDING OF DUTY

CYCLE RATINGS can cause damage to the

welding power source.

• Do not exceed indicated duty cycles.
