Protect other nearby personnel with suitable, non-flammable screening and/or warn them not to
watch the arc nor expose themselves to the arc rays or to hot spatter or metal.
Fire
Welding spark may cause fire, make sure there is no tinder stuff around the welding area.
Noise——Excessive noises will be harmful to hearing .
Use ear protector or others to protect your ears.
Warn looker-on that noise is harmful to hearing.

2
Malfunction——When trouble happens, contact with authorized professionals
If trouble happens during installation and operation, please follow this manual instruction to
check up.
If you fail to fully understand the manual, or fail to solve the problem with the instruction, you
should contact the suppliers or the service center for professional help.
WARNING！
Creep age-protecting switch should be added when using the machine！！！
MACHINE DESCRIPTION
The MIG-200D portable MIG welder, uses ac single phase 230V, 50HZ with time delayed fuse or
circuit breaker. The key features are as below:
● Advanced IGBT Inverter technology.
● MIG / MMA Function.
● Thermal protection.
● Stepless welding current and voltage setting. Can meet different welding processes.
● Auto-compensation for voltage fluctuation.
● Less spatter, deep penetration, beautiful welding seam.
WARNING！
The machine is mainly used in industry. It will produce radio wave, so the worker
should make fully preparation for protection.

INSTALLATION INSTRUCTION
The machine is equipped with power voltage compensation system. When power voltage fluctuates
between±10% of rated voltage, it still can work normally.
When use long cable, in order to prevent voltage form going down, bigger section cable is suggested.
If cable is too long, it may affect the performance of the power system. So we suggest you to use
configured length.
1. Make sure heat emission holes of the machine not blocked or covered.
2. Ground the cables with section area no less than 6mm2to the housing, the way is
connecting screw in the back of the power source to ground device, or make sure ground
terminal of power socket is firmly connected. Both ways can be used for absolute safety.
3. Correctly connect the arc torch or holder according to the sketch. Make sure the cable, holder and
fastening plug have been connected with the ground. Put the fastening plug into the fastening
socket at the “-”polarity and fasten it clockwise.
4. Put the fastening plug of the cable to fastening socket of “+” polarity at the front panel, fasten it
clockwise, and the earth clamp at the other terminal clamps the work piece.
5. Please pay attention to the connecting polarity,
DC welding machine has two connecting ways: positive connection and negative
connection. Positive connection: holder connects with “-”terminal, while workpiece with the
“+” terminal. Negative connection: work piece with the“-” terminal, holder with the “+”
terminal. Choose suitable way according to working demands. If unsuitable choice, it will
cause unstable arc, more spatters and conglutination. If such problems occur, please
change the polarity of the fastening plug.
6. According to input voltage grade, connect power cable with power supply box of relevant

voltage grade. Make sure there is no mistake and the voltage of power supply does not
exceed permission range. After the above job, installation is finished and welding is
available.

OPERATION INSTRUCTION
WARNING！
Before operation , please make sure all the power is turned off. The right process is
to connect the welding cable and ground cable to the machine first, and make sure they are
firmly connected and then put the power plug to the power source.
1. After the installation, turn on the power switch, screen indicator will show , The ammeter and fan is
beginning to run.
2. Set the welding current and wire speed and get the best welding performance.

NOTES OR PREVENTIVE MEASURES
1. Environment
1）The machine should be operated in dry environments with humidity levels of max 90%.
2）Ambient temperature should be between -10 to 40 degrees centigrade.
3）Avoid welding in sunshine or drippings. Do not let water sprinkle on the machine.
4）Avoid welding in dust area or the environment with corrosive gas.
5）Avoid gas welding in the environment with strong airflow.
2. Safety norms
The welding machine is installed with protection circuit of over voltage, over current and over heat.
When voltage, output current and temperature of machine exceed the required standard, welding
machine will stop working automatically. However, overuse (such as over voltage) will still result in
damage to the welding machine. To avoid this, the user must pay attention to the following.
1) The working area is adequately ventilated！
The welding machine is powerful machine, when it is being operated, it is generated by high
currents, and natural wind will not satisfy the machines’ cooling demands. So there is a fan
of the machine to cool down machine. Make sure the intake is not in block or covered, it is
0.3 meter from welding machine to objects of environment. User should make sure the
working area is adequately ventilated. It is important for the performance and the longevity
of the machine.
2) Do not over load！
Operation complies with duty cycle strictly. Keep welding current not exceed max duty cycle
current. Over-load current will damage and burn up machine. IF welding time is exceeded
duty cycle limited, welding machine will stop working for protection. Because machine is
overheated, temperature control switch is on “ON’’ position and the indicator light is red. In
this situation, you don’t have to pull the plug, in order to let the fan cool the machine. When
the indicator light is off, and the temperature goes down to the standard range, it can weld
again.
3) No over voltage！
Power voltage can be found in diagram of main technical data. Automatic compensation
circuit of voltage will assure that welding current keeps in allowable range. If power voltage
is exceeding allowable range limited, it will damage to components of machine. The operator
should understand this situation and take preventive measures.
4) There is a grounding screw behind welding machine, with a grounding marker on it. Before
operation, welding crust must be grounded reliable with cable which section is over 6mm2, in
order to prevent from static electricity, and accidents because of electricity leaking.

MAINTENANCE
1. Remove dust by dry and clean compressed air regularly. If welding machine is operated in
environment where strong smoke and polluted air is present, the machine needs to be cleaned at
least once a month.
2. Pressure of compressed air must be within reasonable range in order to prevent damage to small
and sensitive components in the machine.
3. Check internal circuit of welding machine regularly and make sure the circuit connections are
connected correctly and tightly (especially plug-in connector and components). If scale and rust
are found, please clean it, and connect again tightly.
4. Prevent water and steam from entering into the machine. If that happens, please blow it dry and
check insulation of machine.
5. If welding machine will not be used for long time, it must be put into the packing box and stored in
dry and clean environment.
