SOLUTION TO FAULT
6. Arc-striking difficult and easily pauses under CUT
6.1 Make sure the electrode is of good quality.
6.2 When cutting current is too small but the air flow is too high, arc will be cut easily
by powerful cooling capability.
6.3 Output voltage will be consumed by using prolonged cable, so please shorten the
cable.
7. Electrodes or tips consume too fast
7.1
Too high current is used with too small diameter tips.
7.2 Air pressure is too small to cool down the tips.
8. The arc can’t penetrate the steel plate completely or there is too much slag to
continue cutting
8.1 Please choose suitable model with higher current if the power is not enough for
the metal working.
8.2 Please replace the nozzle or tip once they were burnt badly.
9. Welding spot becoming black
It means the welding spot is oxygenated without good protection, and please check
the followings:
9.1 Make sure the argon cylinder is open and has enough pressure which should be
above 0.5 MPa.
9.2 Make sure the pressure valve is open and has enough flow. In order to save gas,
you can choose different flow according to the different welding current, but it may
result in that the protective gas can’t cover the welding spot entirely. Argon flow not
less than 3L/min is suggested.
9.3 The simple method to check whether the argon flows out or not is to feel the gas
through nozzle with your finger.
9.4 Gas flow is not well sealed or argon is not pure.
9.5 If air flow is too strong, it may low down the welding quality.

ATTENTION
1. Environment
1.1 The machine can perform in environment with dry air of a dampness proportion of
max 90%.
1.2 Ambient temperature should be between -10°C to 40°C.
1.3 Avoid welding in sunshine or drippings.
1.4 Please do not use the machine in the air which is polluted with conductive dust or
corrosiveness gas.
2. Safety points
The welding machine has adopted protection circuit to avoid broken under over
voltage, over current and overheat. When voltage, output current and temperature of
machine exceed the standard level, the unit will stop working automatically. In order
to avoid the damage to the unit, operator must pay attention to the following:
2.1 Please make sure the working area is adequately ventilated!
The machine adopts air cooling, so be sure the intake is not in block or covered. It
should be more than 0.3 meter from welding machine to the surroundings. And
good ventilation is important for better performance and the longevity of the unit.
2.2 No over load!
Please avoid overload using as it will shorten the machine life.
Normally it's overload if the OC led is on during welding process, so please stop
welding immediately and continue to work after OC led is off.
2.3 No over voltage
Automatic compensation circuit of voltage will assure that welding current is kept in
allowable arrangement. If power voltage exceeds the limitation, it will damage the
welder. In that case, please take relevant preventive measures.
2.4 Assure the ground screw is well connected
There is a ground screw with the symbol at the rear panel of the unit. Choose
section of inducting cable over 6mm
2
and reliably grounding to prevent from static
electricity and leaking.

SECURITY CAUTION
Please make good protection as there will be possibility of harm during arc
welding process. For more details please refer to the Operator Safety Guide,
which complies with the preventive requirements of the manufacturer.
Electric shock-----may be fatal
Install the earth cable according to the standard
No touching electric parts with bare or wet hands or wet clothes
Make sure that the working piece and you are in under insulation
circumstances
Make sure that your working is in safe condition
Smoke-----may be harmful
Keep your head out of the smoke
Make sure the air is flowing to avoid breathing in the smoke in welding
process
Arc radiation-----may be harmful to your eyes and skin
Wear suitable welding mask and clothes to protect your eyes and skin
Use suitable screen or curtain to keep the onlookers away from the emission
Fire
Welding sparks may cause fire, make sure that welder is close to non-
flammable material
Noise----excessive noise may be harmful to your hearing
Please wear something to protect your ears from the noises
Warn the onlookers hidden harm may be caused by the noise
Break-down: ask the professional for help
If you have any problems in setting up or operating, please turn to this manual
first.
If you still can not understand after reading this manual, please contact your
supplier or manufacturer to get professional assistance.

INSTALLMENT & OPERATION
6. Please adjust appropriate cutting current according to the thickness and material of
the work-piece and the cutting craft as well.
7.The cutter will start to work soon once the torch touches the work-piece with a certain
angle.

INSTALLMENT & OPERATION
The welding machine is equipped with power voltage compensation device. When
power voltage fluctuates between ±15% of rated voltage, it can still work normally.
As using long cables, in order to reduce the voltage drop, cable of bigger section is
suggested. If cable is too long, it may affect the performance of the power system as
well as other properties, so we recommend you to use the configured length.
1. Be sure the vents are not blocked, lest cooling system will not work.
2. Well connect the protection gas source. Gas supply includes gas cylinder, argon
regulator and gas hose. Connecting part of gas hose should be fastened with hose
clamp to prevent from leaking gas or air admission.
3. Use inducting cable with the section not smaller than 6 mm² to connect the housing
to the ground. The way is from the ground-connecting screw to the earth device.
