of damage or injury to operators or

others. Be sure to read each of them,

since all of them are important for

safe operation.

•The meaning of the words and

symbols is as follows.

Do not touch the inside of the Product unnecessarily.

Since very high voltages are charged to the inside of this product, it is very

dangerous to touch it unnecessarily.

Any person other than service personnel, or authorized representatives’

personnel must not touch the inside.

Never disassemble, repair or modify the Product.

These actions can cause electric shock and fire.

If any part needs to be checked or repaired, contact us or your distributor for

help.

Never burn, destroy, cut, crush or chemically decompose the Product.

This product incorporates parts containing gallium arsenide (GaAs).

Denotes operations and practices

that may imminently result in serious

injury or loss of life if not correctly

followed.

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.

Ground the equipment.

If the Transformer Selector 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.

Do not use any damaged power cable, connecting cable and plug.

That can cause electric shock, short circuits 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 flash 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-650A

1. Special Precautions

1-3

Connect the cords and cables securely.

Loose connection can cause fire and electric shock.

Do not splash water on the equipment.

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 equipment on firm and level surface.

If the equipment falls over or drops from an uneven surface, injury may

result.

Do not sit on or do not put things on it.

Sitting on it, or putting things on it may cause malfunction.

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 this equipment with a blanket, cloth, etc.

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

Use ear protectors.

Loud noises can damage hearing.

Keep a fire extinguisher nearby.

Make sure there is a fire extinguisher in or near the welding shop in case of

fire.

Regularly inspect and maintain the equipment.

Regular inspect and maintenance is essential to safe operation of the

equipment. If you see any damage, make necessary before starting the

operation.

(2) Precautions for Handling

When transporting or moving the Selector, do not lay it down. Also, handle the

Selector with care so as not to make an impact such as drop on it.

Install the Transformer Selector on a firm and level surface. If it is used inclined or

on its side, it may have a malfunction.

Do not install this Transformer Selector in the following places:

▪Where there is considerably damp (humidity is higher than 90%).

▪Where the ambient temperature is above 40°C or below 5°C.

▪Where there is nearby high noise source.

▪Where the Selector may be exposed to chemicals.

▪Where moisture may be condensed on the surface of the Selector.

▪Where there is considerable dirt.

▪Where the Selector may be subjected to vibration or impact.

▪Where an altitude is above 1000 meters.

If the outside of the Selector is stained, wipe it with a dry cloth or a moistened

cloth. If it is badly stained, use diluted neutral detergent or alcohol to clean it. Do

not use paint thinner, benzene, etc., which can discolor or deform the parts.

Do not put screws, coins, etc., in the Selector, as they may cause a malfunction.

Operate the Selector according to the method described in this operation manual.

The Selector is not equipped with auxiliary power such as an outlet for lighting.

The welding transformer IPB-5000A is required to use the Selector.

(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.

2. Features

2-1

2. Features

MA-650A is a transformer selector exclusively used for Inverter-type Welding

Power Supply IPB-5000A (Here in the followings, simply shown as IPB-5000A.).

(Note)

As the input of a thermostatic sensor in a welding power supply has been

connected in series with each welding transformer in the conventional

transformer selector, a dummy connector has been necessary for an unused

I/O connector (4.(2)④[SENS] Cable Connector). However, the dummy

connector is not required because of the modification of a control method in

MA-650A.

MA-650A can switch the output power of a welding power supply into a maximum

of 5 transformers one by one.

MA-650A-00 is for IPB-5000A-00-01/-00-02/-00-04/-00-05 of 380–480V AC, Input

Voltage.

MA-650A-01 is for IPB-5000A-00-00/-00-03 of 200–240V AC, Input Voltage.

MA-650A-02 is for IPB-5000A-03-06 of 200–240V AC, Input Voltage.
