Do not touch the inside of the Equipment unnecessarily

Since very high voltages are applied to the interior of this Equipment, it is

dangerous to touch it unnecessarily. Do not open the cover for the purposes

other than replacing the battery. When trouble occurs and inspection or repair

is needed, consult us.

Never disassemble, repair or modify the Equipment

These actions can cause electric shock and fire. Do not do anything other than

1. Special Precautions

1-2

Do not put your hands between the electrodes

When welding, keep your fingers and hands away from the electrodes.

Do not touch any welded part or electrodes during welding and just after

welding finished

The welded part of a workpiece, electrodes and arm are very hot.

Do not touch them; otherwise you may be burnt.

Do not splash water on the Equipment

Water splashed over the electric parts can cause electric shock and short

circuits.

Connect the specified cables securely

Cables of insufficient current capacities and loose connections can cause fire

and electric shock.

Do not damage the connecting cables

Do not tread on, twist or tense any cable. The connecting cables may be

broken, and that can cause electric

shock and fire. When repair or

replacement is needed, consult us.

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 flash and expulsion directly during welding, your eyes may

be damaged. If any surface flash and expulsion gets in your eye, you may

lose your eyesight.

WARNING

MA-660A

1. Special Precautions

1-3

Do not place a water container on the Equipment

If water spills, insulation will deteriorate, and this may cause electric leak and

fire.

Keep combustible matter away from the Equipment

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 Equipment with a blanket, cloth, etc.

If such a cover is used, it may be overheated and burn.

Do not use this Equipment for purposes other than welding

Use of this Equipment in a manner other than specified can cause 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 Equipment periodically

Maintain and inspect the Equipment periodically, and repair any damage

nearby before starting operation.

(2) Precautions for Handling

■Handle the Transformer with care so as not to make an impact such as drop on

it.

■Do not use this Equipment in the following places:

・damp places (where humidity is higher than 90%),

・hot or cold places (where temperatures is above 40°C or below 5°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 Equipment 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 Equipment.

■Do not put a screw, a coin, etc., in the Equipment, since they can cause a
