1.0 GENERAL INFORMATION

1.01 Notes, Cautions and Warnings

Throughout this manual, notes, cautions, and warnings are used to highlight important information. These
highlights are categorized as follows:
NOTE
An operation, procedure, or background information which requires additional emphasis or is helpful in
efficient operation of the system.

CAUTION

A procedure which, if not properly followed, may cause damage to the equipment.

WARNING

A procedure which, if not properly followed, may cause injury to the operator or others in the operating area.

1.02 Important Safety Precautions

WARNING

OPERATION AND MAINTENANCE OF CUTTING EQUIPMENT CAN BE DANGEROUS AND HAZARDOUS
TO YOUR HEAL TH.
To prevent possible injury, read, understand and follow all warnings, safety precautions and instructions
before using the equipment. Call your local distributor if you have any questions.

GASES AND FUMES
Gases and fumes produced during the Arc welding or cutting process can be dangerous and hazardous to
your health.

z Keep all fumes and gases from the breathing area. Keep your head out of the welding fume plume.
z Use an air-supplied respirator if ventilation is not adequate to remove all fumes and gases.
z 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 processes. You must be very careful when cutting or welding
any metals which may contain one or more of the following:
Antimony Arsenic Barium Beryllium Cadmium Chromium Cobalt Copper Lead
Manganese Mercury Nickel Selenium Silver Vanadium

z Always read the Material Safety Data Sheets (MSDS) that should be supplied with the material you

are using. These MSDSs will give you the information regarding the kind and amount of fumes and
gases that may be dangerous to your health.

z Use special equipment, such as water or down draft welding/cutting tables, to capture fumes and

gases.

z Do not use the cutting torch in an area where combustible or explosive gases or materials are

located.

z Phosgene, a toxic gas, is generated from the vapors of chlorinated solvents and cleansers. Remove

all sources of these vapors.

ELECTRIC SHOCK
Electric Shock can injure or kill. The cutting 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.

z Never touch any parts that are electrically “live” or “hot.”
z Wear dry gloves and clothing. Insulate yourself from the work piece or other parts of the cutting

circuit.

z Repair or replace all worn or damaged parts.
z Extra care must be taken when the workplace is moist or damp.
z Install and maintain equipment according to NEC code, refer to relative standards.
z Disconnect power source before performing any service or repairs.
z Read and follow all the instructions in the Operating Manual.

FIRE AND EXPLOSION

Fire and explosion can be caused by hot slag, sparks, or the arc weld.

z Be sure there is no combustible or flammable material in the workplace. Any material that cannot be

removed must be protected.

z Ventilate all flammable or explosive vapors from the workplace.
z Do not cut or weld on containers that may have held combustibles.
z Provide a fire watch when working in an area where fire hazards may exist.
z Hydrogen gas may be formed and trapped under aluminum workpieces when they are cut

underwater, or while using a water table. Do not cut aluminum 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 hearing.

z To protect your hearing from loud noise, wear protective ear plugs and/ or ear muffs. Protect others

in the workplace.

z Noise levels should be measured to be sure the decibels (sound) do not exceed safe levels.

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.

z 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.

z Wear welding gloves and suitable clothing to protect your skin from the arc rays and sparks.
z Keep helmet and safety glasses in good condition. Replace lenses when cracked, chipped or dirty.
z Protect others in the work area from the arc rays. Use protective booths, screens or shields.

1.03 Transporting methods

These units are equipped with a handle for carrying purposes.

WARNING: ELECTRIC SHOCK can kill.

DO NOT TOUCH live electrical parts. Disconnect input power conductors from de-energized supply

line before moving the cutting power source.

WARNING: FALLING EQUIPMENT can cause serious personal injury and
equipment damage.

z Lift unit with handle on top of case.
z Use handcart or similar device of adequate capacity.
z If using a fork lift vehicle, place and secure unit on a proper skid before transporting.
