MD Series
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 this Power Supply
If the Power Supply is not grounded, you may get an electric shock when
there is trouble, or when electricity leaks.
Apply Single-phase, 100
―
120/200
―
240V AC power supply
Application of a voltage out of the specified range can cause fire and electric
shock.
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 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
！

MD Series
1. Special Precautions
1-3
Do not splash water on the Power Supply
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 Power Supply on firm and level surface
If the Power Supply falls or drops, injury may result.
Do not place a water container on the Power Supply
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 Power Supply with a blanket, cloth, etc.
If such a cover is used, it may be overheated and burn.
Do not use this Power Supply for purposes other than welding
Use of this Power Supply 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 Power Supply periodically
Maintain and inspect the Power Supply periodically, and repair any damage
nearby before starting operation.
Avoid contact of any metal object such as tool with the output terminals
or the metal part of the secondary conductor
The contact situation can cause the shorted state and the contact portion
may be overheated and scattered.

(2) Precautions for Handling
■When transporting or moving the Power Supply, do not lay it down. Also,
handle the Power Supply with care so as not to make an impact such as drop
on it. Moving the Power Supply by hand must be done by at least two people.
■Install this Power Supply on a firm and level surface. If it is inclined,
malfunction may result.
■Do not install this Power Supply in the following:
•Damp places where humidity is higher than 90%,
•Hot or cold places where temperatures are 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 Power Supply 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 Power Supply, since they can cause a
malfunction.
■Operate the Power Supply according to the method described in this operation
manual.
■Operate the switches and buttons carefully by hand. If they are operated
roughly or with the tip of a screwdriver, a pen, etc., this will cause malfunction
or damage.
■Operate the switches and buttons one at a time. If two or more of them are
operated at a time, the Power Supply may have trouble or may be broken.
■The Power Supply is not equipped with auxiliary power such as an outlet for
lighting.
■The welding head and the secondary conductor for connecting the welding
head with the Power Supply are separately needed to use the Power Supply.
■The I/O signal line and RS-485 communication signal line to start the Power
Supply are not attached. Solder lines to the attached I/O connector and
RS-485 connector.
(3) On Disposal

2. Features
2-1
2. Features
MD-A10000A and MD-B5000A are transistor welding power supplies for precision
welding. Small power supply units can be used since all welding is powered by energy
accumulated in a capacitor.
MD-A10000A: Standard type
MD-B5000A: Polarity switching type
■The switching method adopted for welding current control permits the small model to
achieve high output and high efficiency.
■Select any of the following three control methods:
Constant-current control ( )
Realizes a stable welding since a fixed current is supplied regardless of the
resistance of workpiece.
Constant-voltage control ( )
Controls the voltage between electrodes. Welding free of surface flash and
expulsion can be performed since the voltage is fixed from the start and the
current is reduced even the welding of material having high specific resistance
and the welding of workpiece having high contact resistance such as cross wire.
Combination control of constant-current and constant-voltage ( )
In the early stage of welding, welding free of surface flash and expulsion can be
performed by the constant-voltage setting. The weld time to start of constant
current can be adjusted.
■The quick welding current rise is optimal for fine welding.
Current of the later stage is
suppressed and excessive
burn is prevented.
Only the welding
start part can be
adjusted by the
constant-voltage
setting.
Voltage becomes
high and surface
flash and expulsion
can easily occur.
