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.

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.

5. How to Connect
(1) Connection
Connect MA-650A to IPB-5000A by Output Cables and [SENS] Cables ((3)).
Uncover MA-650A for the connection.
See (2) Connection Diagram.
MA-650A is for 5 Channels’ use.
Although a maximum of 5 transformers can be switched, even 2, 3 or 4 transformers
also can be used. In the case of 4 or less transformers used, the transformers have
to be connected to “OUT1” at the beginning, and then to “OUT2”, “OUT3”
consecutively.
Be sure to connect no articles to unused terminal strips and connector.
①Output Cable Connection Terminal Strip (M5)
Connect Output Cable (U, V) from IPB-5000A and Output Cables (U1 to U5, V1 to
V5) connected to each transformer. Connect them correctly according to the
instruction for the connection.
If they are incorrectly connected, the equipment results in breakdown.
Be sure to turn off IPB-5000A when connecting or changing Cables.
②Copper Bar for Connecting Ground [E, E1 to E5] (M5)
Connect Output Cable from IPB-5000A and grounding cables of Output Cables
connected to each transformer. The ground of E and E1 to E5 are all connected in
common.

6. How It Works
For the movement and sequence timing, refer to 9. (8) Behavior in TRANS SCAN
MODE in Operation Manual packaged with IPB-5000A.
All circuit power supply and switching signals are output through the I/O Connector of
IPB-5000A to the OUT Connector of MA-650A.
Turning on the switch of IPB-5000A makes POWER Lamp on the front panel lighting,
and the weld starting makes the lamps of CHANNEL (1to 5) lighting through which the
weld current flows.
