1. Special Precautions
(1) Safety Precautions
Before using, read "Safety Precautions"
carefully to understand the correct method
of use.
■These precautions are shown for safe use
of our products and for prevention of
damage or injury to operators or others.
Be sure to read each of them, since all of
them are important for safety.
■The meaning of the words and symbols is
as follows.
These symbols denote
"prohibition".
They are warnings
about actions out of the
scope of the warranty
of the product.
These symbols denote
actions which
operators must take.
Each symbol with a
triangle denotes that
the content gives
notice of DANGER,
WARNING or
CAUTION to the
operator.
Denotes operations and practices that
may imminently result in serious injury
or loss of life if not correctly followed.
Denotes operations and practices that
may result in serious injury or loss of
life if not correctly followed.
Denotes operations and practices that
may result in personal injury or damage
to the equipment if not correctly followed.
Do not touch the “Terminal block” on the rear panel of the Welding
Transformer
Since very high voltage is applied to the “Terminal block”, it is very dangerous
to touch it unnecessarily. When connecting or disconnecting a cable, be sure to
turn off the power. After connecting the cable, install the terminal cover so that
operator can not touch the terminal block during work.
Never disassemble, repair or modify the Welding Transformer
These actions can cause electric shock and fire. Consult us or your distributor
for inspection and repair.
Never burn, destroy, cut, crush or chemically decompose the Welding
Transformer
This product incorporates parts containing gallium arsenide (GaAs).

1. Special Precautions
1-2
Do not put your hands between the electrodes
When welding, keep your fingers and hands away from the electrodes.
Ground the Welding Transformer
If the Transformer is not grounded, you may get an electric shock when there
is trouble, or when electricity leaks.
Use the rated voltage
Applying a voltage exceeding rated voltage can cause abnormal heat and
fire.
Do not touch +/- terminal, secondary cable, any welded part or electrodes
during welding and just after welding finished
These parts are very hot. Do not touch them; otherwise you may be burnt.
Do not damage the power cable and connecting cables
Do not tread on, twist or tense any cable. The power cable and connecting
cables may be broken, and that can cause electric shock and fire. If any part
needs to be repaired or replaced, consult us or your distributor.
Wear protective glasses
If you look at the flash directly during welding, your eyes may be damaged.
If any spatter gets in your eye, you may lose your eyesight.
Stop the operation if any trouble occurs
Continuous operation after occurrence of a trouble such as burning smell,
abnormal sound, abnormal heat, smoke, etc. can cause electric shock and
fire. If such a trouble occurs, immediately consult us or your distributor.
Persons with pacemakers must stay clear of the welding machine
A person who uses a pacemaker must not approach the welding machine or
walk around the welding shop while the welding machine is in operation,
without being permitted by his/her doctor. The welding machine generates a
magnetic field and has effects on the operation of the pacemaker while it is
turned on.
Protective gear must be worn
Put on protective gear such as protective gloves, long-sleeve jacket, leather
apron, etc. Spatter can burn the skin if they touch the skin.

1. Special Precautions
1-3
Do not use this Welding Transformer for purposes other than welding
Use of this equipment in a manner other than specified can cause an electric
shock and fire.
Use proper tools (wire strippers, pressure wire connectors, etc) for
termination of the connecting cables
Do not cut the conductor of wire. A flaw on it can cause fire and electric
shock.
Install the Welding Transformer on firm and level surface
If the Transformer falls or drops, injury may result.
Do not splash water on the Welding Transformer
Water splashed over the electric parts can cause electric shock and short
circuits.
Do not place a water container on the Welding Transformer
If water spills, insulation will deteriorate, and this may cause electric leak and
fire.
Keep combustible matter away from the welding machine
Spatter can ignite combustible matter. If it is impossible to remove all
combustible matter, cover them with non-combustible material.
Do not cover the Welding Transformer with a blanket, cloth, etc.
If such a cover is used, it may be overheated and burn.
Keep a fire extinguisher nearby
Keep a fire extinguisher in the welding shop in case of fire.
Use ear protectors
Loud noises can damage hearing.
Maintain and inspect the Welding Transformer periodically
Maintain and inspect the Transformer periodically, and repair any damage
nearby before starting operation.

1. Special Precautions
1-4
(2) Precautions for Handling
When transporting or moving the Transformer, do not lay it down. Also, handle
the Transformer with care so as not to make an impact such as drop on it.
Moving the Transformer by hand must be done by at least two people.
Install this Welding Transformer on a firm and level surface. If it is inclined,
malfunction may result.
Do not install this Welding Transformer in the following:
•Damp places where humidity is higher than 90%,
•Hot or cold places where temperatures are above 45°C or below 5°C,
•Places near a high noise source,
•Places where chemicals are handled,
•Places where water will be condensed,
•Dusty places,
•Places exposed to large amounts of vibration or shock, and
•Places at an altitude above 1000 meters.
Clean the outside of the Welding Transformer with a soft, dry cloth or one wet
with a little water. If it is very dirty, use diluted neutral detergent or alcohol. Do
not use paint thinner, benzine, etc., since they can discolor or deform the
Welding Transformer.
For the water-cooled products, use city water or water for industrial use. Note
that the water temperature, flow rate and water pressure fall within the specified
range.
Do not put a screw, a coin, etc., in the Welding Transformer, since they can
cause a malfunction.
Operate the Welding Transformer according to the method described in this
Operation Manual.
The welding power supply, the welding head, and the cables for connecting the
welding power supply, the welding head and the Transformer are separately
needed to use the Transformer.
When the Transformer has the I/O signals, the I/O signal line to start the
Transformer is not attached.
(3) On Disposal
This product incorporates parts containing gallium arsenide (GaAs). At the time of
disposal, separate it from general industrial waste or domestic waste and carry out
the disposal in accordance with applicable laws and regulations.
