Never disassemble, repair or modify the device.
These actions can cause electric shock and fire. Do not do anything other than
the maintenance described in the operation manual.
Do not insert your fingers or hands between the electrodes.
When welding, keep your fingers and hands away from the electrodes.
Do not touch any welded part or electrode during welding or just after
completion of welding.
The welded parts of a workpiece, electrodes, and the arm are very hot.
Do not touch them; burns may result.
Apply the specified supply voltage.
Application of a voltage outside the specified range may result in fire or electric
shock.
Use the specified cables and connect them securely.
Failure to do so or improper connection may result in a fire or electric shock.
Keep the power and connection cables free of damage.
Do not walk on, twist or tug the cables.
Damaged cable may result in an electric shock, short circuit, or fire.
For repair or replacement, contact your dealer or Amada Miyachi Co., Ltd.
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 Amada Miyachi Co., Ltd. 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. Spatters can burn the skin if they touch the skin.
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.

Do not expose to water or other liquid.
Exposing electrical components to water or other liquid may result in electric
shock or short-circuiting.
Keep combustible matter away from the device.
Spatter may ignite combustible matter. If it is impossible to remove all
combustible matter, cover it with non-combustible material.
Do not cover the device with a blanket, cloth, etc.
Do not cover the device with a blanket, cloth, etc. while it is in use.
The cover may be overheated and burned.
Wipe off dust from the power plug and securely insert it all the way.
Dust or improper insertion may lead to the plug heat up and catch fire.
Hold the power plug when removing or inserting it.
Removing the power plug by pulling on the cable may damage the power
cable, resulting in an electric shock or causing the cable to catch fire.
If you do not use the device for extended periods, remove the power
plug from the outlet.
Failure to do so may deteriorate the insulation, resulting in an electric shock,
current leakage or fire.
Keep a fire extinguisher nearby.
Keep a fire extinguisher in the welding shop in case of fire.
Maintain and inspect the device periodically.
Maintain and inspect the device periodically, and repair any damage nearby
before starting operation.
Use ear protectors.
Loud noises can damage hearing.

(2) Handling Precautions
■ Avoid the following locations when installing the device:
•Humid location (humidity of above 90%)
•Extremely hot (above 40°C) or cold (below 0°C) locations
•Near a high noise source
•Location where chemical substances, etc. are handled
•Location where condensation occurs
•Dusty location
•Location exposed to direct sunlight
•Location that is inclined, insecure, unstable, or weak
■ Check the voltage and power frequency before installation.
■ Keep the exterior clean with a soft cloth or cloth lightly dampened with water. For
stains, clean them off using a diluted neutral detergent or alcohol.
Do not use thinner or benzene as they may cause discoloration or deformation.
■ To prevent malfunction, do not allow any foreign objects such as screws or coins to
enter the device.
■ Operate the device according to the procedure described in the Operation Manual.
■ Operate the buttons with care. Rough operation or the use of a tool or pen tip may
result in damage or malfunction.
■ Use fully charged batteries. Even if the display does not prompt you to charge the
batteries, using batteries that are not fully charged may result in degraded
measurement accuracy. (Before using the tester for the first time, always charge the
batteries.)
■ Use only the included or specified chargers.
■ Do not charge for more than 48 hours.
