About the machine
The welding machine is a rectifier adopting the most advanced inverter
technology.
The development of inverter gas-shielded welding equipment profits from the
development of the inverter power supply theory and components. Inverter
gas-shielded welding power source utilizes high-power component IGBT to transfer
50/60HZ frequency up to 100KHZ, then reduce the voltage and commutate, and
output high-power voltage via PWM technology. Because of the great reduce of the
main transformer’s weight and volume; the efficiency increases by 30%. The
appearance of inverter welding equipment is considered to be a revolution for
welding industry.
CO2 shielded welding equipment adopts the most advanced inverter
technology by our. Inside of the machine is equipped with electronic reactor circuit
which can accurately control the process of the electric short transition and blending
transition and result excellent welding characteristic. Comparing with synergic
welding machine and other machine, it has the following advantages: stable wire
speed, compact, power saving, no electromagnetic noise. Continuous and stable
operation with small current, especially suitable for welding sheet of low-carbon
steel, alloyed steel and stainless steel. Automatic voltage pulsation compensation

capability, small sparkle, good arcing, uniform welding pool, high duty cycle and so
on.

Installment
The welding equipment is equipped with power voltage compensation set.
When power voltage changes between±15% of rated voltage, it still works normally.
When using long cable, in order to minimize the reduce of voltage, big section
cable is suggested. If the cable is too long, it will affect the performance of arcing
and other system function, so stated length is suggested.
1、Make sure the intake of the machine is not covered or blocked to prevent the
malfunction of the cooling system.
2、Use earth cable that the section no less than 6mm2to connect the housing and
earth, the method is from the connection in the back of the machine to the
earth set, or make sure the earth end of power switch reaches the earth. Both
ways can be used for better security.
Set up for Welding：
1) Connect the gas flask with CO2 decompression flow meter and the CO2 mouth
behind the machine via gas cable.
2) Insert the swift plug of earth cable into the swift socket in the front panel.
3) Set the wire wheel with wire on the wheel axis, the wheel hole should be

matched with the wheel fixer.
4) Choose wire slot according to wire size.
5) Loosen the screw of wire-pressing wheel, put the wire into slot via wire-lead tube,
tune the Wire-pressing wheel to fix wire from gliding,but pressure should be suitable
in case the wire distorts and affects wire sending.
6) Wire roll should turn clockwise rotation to let out wire, to prevent wire from gliding,
wire is usually set to the fixed hole on the wheel side. To prevent the bent wire from
getting stuck, please cut off this part of the wire.
7) The MIG torch has been settled inside of the machine just need put the wire into
the torch by hand.

Operation
1、Put the air switch to “ON” position, open the valve of CO2 cylinder and adjust
the flow.
2、Adjust the wire diameter of the wire machine to rated number according to
wire diameter.
3、Choose torch loophole span based on wire diameter.
4、Tune the voltage knob, speed knob and inductance knob to the right position
based on the thickness of the work piece and mechanics.
5、Press the torch switch to let out the wire to the torch head and begin to work.

NOTES OR PREVENTIVE MEASURES

1、Environment
1）The machine can perform in environment where conditions are dry with a
dampness lever of max 90%.
2）Ambient temperature is between 10 to 40 degrees centigrade.
3）Avoid welding in sunshine or dripaings.
4）Do not use the machine in environment where condition is polluted with
conductive dust on the air or corrosiveness gas on the air.
5）Avoid gas welding in the environment of strong airflow.
2、Safety norms
The welding machine has installed protection circuit of over voltage and current
and heat. When voltage and output current and temperature of machine are
exceeding the rate standard, welding machine will stop working automatically.
Because that will be damage to welding machine, user must pay attention as
following.
1）The working area is adequately ventilated！
The welding machine is powerful machine, when it is being operated, it
generated by high currents, and natural wind will not satisfy machine cool
demands. So there is a fan in inter-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！
The operator should remember to watch the max duty current (Response to the
selected duty cycle).
Keep welding current is not exceed max duty cycle current.
Over-load current will damage and burn up machine.
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 keep in
allowable arrangement. If power voltage is exceeding allowance arrangement
limited, it is damaged to components of machine. The operator should
understand the situation and take preventive measures.

4）There is a grounding screw behind welding machine, there is grounding marker
on it Mantle must be grounded reliable with cable which section is over 6
square millimeter I order to prevent from static electricity and leaking.
5）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.
QUESTIONS IS BE RUN INTO IN WELDING
Fittings, welding materials, environment factor, supply powers maybe have
something to do with welding. User must try to improve welding environment.
A、Arcing-striking is difficult and easy to pause：
1) Make sure the earth cable clincher connects the work piece well.
2) Check each connecting point connected or not.
B、Output current can’t reach rated volume：
That supplied voltage is different from the rated will lead to unconformity of the
output current and the adjusted current. When Supplied voltage lower than the
rated, the max output current will be lower than the rated.
C、Current is not stabilizing when machine is been operating.
It has something with factors as following:
1) Electric wire net voltage has been changed；
2) There is harmful interference from electric wire net or other equipment。
D Welding gap has air hole.
1) Check the gas supply loop leaks or not.
2) Surface of mother material has oil, stain, rust, lacquer or other impurity.
