Denotes operations and practices that
may result in personal injury or damage
to the equipment if not correctly followed.
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.
Do not touch the Terminal Block on the rear panel of the Welding
Transformer
Since very high voltages are applied to the Terminal Block, it is very
dangerous to touch it unnecessarily. When connecting or disconnecting a
cable, be sure to disconnect the power supply.
After connecting the cable, mount 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 maintenance and repair.
Never burn, destroy, cut, crush or chemically decompose the Welding
Transformer
This product incorporates parts containing gallium arsenide (GaAs).
These symbols denote
"prohibition".
They are warnings about
actions out of the scope of the
warranty of the product.
These symb
ols 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.

IT-513B
1. Special Precautions
1-2
IT-513B must be used only with IP-400B Power Supply
The IP-400B supplies a voltage of 300
V AC (4 kHz) to the IT-513B.
Do not use with a power supply other than the IP-400B, otherwise fire or
breakage of the power supply may result.
Ground the Welding Transformer
If the Transformer is not grounded, you may get an electric shock when there
is trouble, or when electricity leaks.
Connect the specified cables securely
Cables of insufficient current capacities and loose connections can cause fire
and electric shock.
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.
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. Surface flash and expulsion can burn the skin if they touch the
skin.
Wear protective glasses
If you look at the surface flash and expulsion directly during welding, your
eyes may be damaged. If any flash or expulsion gets in your eye, you may
lose your eyesight.

1. Special Precautions
1-3
Do not splash water on the Welding Transformer
Water splashed over the electric parts can cause electric shock and short
circuits.
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 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
Surface flash and expulsion 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.
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 ear protectors.
Loud noises can damage hearing.
Keep a fire extinguisher nearby.
Keep a fire extinguisher in the welding shop in case of fire.
Maintain and inspect the Welding Transformer periodically
Maintain and inspect the Transformer periodically, and repair any damage
nearby before starting operation.

(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.
■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 40°C or below 0°C,
•Places near a high noise source,
•Places where chemicals are handled,
•Places where water will be condensed,
•Dusty places, 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.
■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 Transformer is not equipped with auxiliary power such as an outlet for
lighting.
■The welding power supply, the welding head, and the secondary cables for
connecting the welding power supply, the welding head and the Transformer are
separately needed to use the Transformer.
(3) On Disposal
