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 ARC WELDING EQUIPMENT CAN BE DANGEROUS AND
HAZARDOUS TO YOUR HEALTH.
To prevent possible injury, read, understand and follow all warnings, safety precautions and instructions
before using the equipment. Call 86-21-69171135 or 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.
lKeep all fumes and gases from the breathing area. Keep your head out of the welding fume plume.
lUse an air-supplied respirator if ventilation is not adequate to remove all fumes and gases.
lThe 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
ManganeseMercury Nickel Selenium Silver Vanadium
lAlways 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.
lUse special equipment, such as water or down draft welding/cutting tables, to capture fumes and
gases.
lDo not use the welding torch in an area where combustible or explosive gases or materials are
located.
lPhosgene, a toxic gas, is generated from the vapors of chlorinated solvents and cleansers. Remove
all sources of these vapors.

DYNA TWC 901、902 Operating Manual
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.
lNever touch any parts that are electrically “live” or “hot.”
lWear dry gloves and clothing. Insulate yourself from the work piece or other parts of the welding
circuit.
lRepair or replace all worn or damaged parts.
lExtra care must be taken when the workplace is moist or damp.
lInstall and maintain equipment according to NEC code, refer to relative standards
lDisconnect power source before performing any service or repairs.
lRead 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.
lBe sure there is no combustible or flammable material in the workplace. Any material that cannot be
removed must be protected.
lVentilate all flammable or explosive vapors from the workplace.
lDo not cut or weld on containers that may have held combustibles.
lProvide a fire watch when working in an area where fire hazards may exist.
lHydrogen gas may be formed and trapped under aluminum workpieces when they are cut
underwater, or while using a water table. Donot 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.
lTo protect your hearing from loud noise, wear protective ear plugs and/ or ear muffs. Protect others
in the workplace.
lNoise 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.
lTo protect your eyes, always wear a welding helmet or shield. Also always wear safety glasses with
side shields, goggles or other protective eye wear.
lWear welding gloves and suitable clothing to protect your skin from the arc rays and sparks.
lKeep helmet and safety glasses in good condition. Replace lenses when cracked, chipped or dirty.
lProtect 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 TOUCHlive electrical parts. Disconnect input power conductors from de-energized supply
line before moving the welding power source.
WARNING: FALLING EQUIPMENT can cause serious personal injury and
equipment damage.
lLift unit with handle on top of case.
lUse handcart or similar device of adequate capacity.
lIf using a fork lift vehicle, place and secure unit on a proper skid before transporting.

2.0 INSTALLATION RECOMMENDATION
Installation Environment
DYNA TWC series is designed for use in hazardous environments.
Examples of environments with increased hazardous environments are-
In locations in which freedom of movement is restricted, so that the operator is forced to perform the work
in a cramped (kneeling, sitting or lying) position with physical contact with conductive parts; In locations which
are fully or partially limited by conductive elements, and in which there is a high risk of unavoidable or
accidental contact by the operator, or in wet or damp hot locations where humidity or perspiration
considerable reduces the skin resistance of the human body and the insulation properties of accessories.
Environments with hazardous environments do not include places where electrically conductive parts in
the near vicinity of the operator, which can cause increased hazard, have been insulated.
Installation Location
Be sure to locate the welder according to the following guidelines:
lIn areas, free from moisture and dust.
lIn areas, free from oil, steam and corrosive
gases.
lIn areas, not exposed to direct sunlight or rain.
lAmbient temperature: between -10 degrees C
to 40 degrees C.
lIn areas, not subjected to abnormal vibration or
shock.
lPlace at a distance of 304.79mm or more from
walls or similar that could restrict natural airflow
for cooling.
WARNING 1
FCW advises that this equipment be electrically connected by a qualified electrician.

6.1 Water Cooler rear panels meet the plume to have good to turn on the earth grounding, by
guarantees the welder safety. When welder operation, should wear protects the mirror,
the glove, puts on protects the clothing.
6.2Ambient temperatures high when big electric current long time continuous working, the
Water Cooler has stopped because of the heat outputting, gets down until the
temperature drop only then restores.
6.3When Water Cooler do not use temporarily, its depository should maintain dryly, cleanly.
The environment relative humidity is not bigger than 85%.
6.4Storing ambient temperature is -25℃~ +55℃.
6.5When long-time does not use, every two months should electrify a time, a humidity month
of every two week should electrify use a time, by use own thermal row of tide.
