Introduction
Thank you for purchasing our welder/cutter.
For your safety, please read this manual and understand its contents before operation.
The Inverter Plasma Cutter is made by the most internationally advanced inverter technology. 50/60 Hz
frequency is inverted to high frequency (frequency that is over 100 KHz) by V-MOSFET, and then reduces the
voltage and rectification current. The inverter power supply generates powerful DC welding current through
PWM technology. Because the inverter technology of the switch power is used, the dimensions and weight of
the main transformer has been reduced significantly and efficiency has increased by 30%. The Piloting Arc
System can strike arcs easily with the principle of high-frequency oscillation. It can supply gas ahead of time and
it can also turn off gas at a later time.
Our Inverter Plasma Cutter has the following characteristics:
•
Stabilizing.
•
Reliability.
•
Lightness.
•
Energy-saving and does not generate any noise.
•
High-speed cutting.
•
Cuts smoothly; no need for further polishing.
The Inverter Plasma Cutter can be used in a wide variety of ways; it is suitable for cutting stainless steel, alloy
steel, mild steel, copper and other coloured-metal materials.
We welcome you to use the product of our company and make suggestions; we will try our best to improve our
products and services.
Guarantee
We give our unreserved guarantee that the Inverter Welding and Cutting Power Source series comply with
IEC974 international safety standard; maintenance for one year from the date of purchase.
Safety
Warning
•
Make sure that the working area is adequately ventilated.
The Inverter Plasma Cutter is light and compact. The electromagnetic fields are generated by high currents.
Natural wind will not sufficiently cool down the components, there is one axial-flow fan within the machine in
order to cool it down.
NOTE: The exhaust shutter must not be blocked or covered within a 0.3m radius from the machine to
objects. Make sure to always keep improving the ventilation of the environment; it is very important for the
Inverter Plasma Cutter.
•
Do not overload!
The limits of the cutting current is strictly in accordance to the maximum allowable current with all kinds of
duty cycles.
Do not exceed the working load in order to prevent the Inverter Plasma Cutter from shortening its life as well
as to avoid burning up the machine.

•
Do not overcharge!
The power voltage range of the Inverter Plasma Cutter is in accordance to the main technical data sheet.
Voltage automatic compensation circuit will prevent it from exceeding the allowable range. If the power
voltage is too high, the internal components could be damaged. User must exercise caution.
•
There is a grounding screw, which is marked “grounding” behind the Inverter Plasma Cutter. Make sure that
the mantle is grounded reliably by a cable whose width is 6 millimetres square in order to prevent electricity
from leaking and producing electro-static.
•
The inter-heat variable component will start if the machine exceeds its duty cycles. That will cause the
Inverter Plasma Cutter to stop working immediately and the red diode to light up. User does not need to
break the circuit; the fan will continue working in order to cool down the machine. Once the temperature is
reduced to a more suitable range, the machine can then be operated again.
•
During welding or cutting, do not switch in-between functions. It could damage the machine.
•
Plug-off the air plug that is connected to the electrode holder to make sure that the holder is separated from
the main machine to avoid an electric shock.
•
A certain switch is needed to protect the machine from voltage-leakage.
•
Pl ease use high-quality welding and/or cutting tools.
•
Operators should be trained and qualified for welding or cutting.
Electric Shock may be Fatal to Life
•
Set the earth cable to standard.
•
Do not touch electrical parts with bare hands, wet hands and/or clothes.
•
Make sure that you and the working piece are properly insulated.
•
Make sure that you prioritise your safety while working.
Smoke may be Harmful to Your Health
•
Keep your head out of any smoke.
•
When welding or cutting, make sure that the air is well-ventilated to avoid breathing in the smoke.
Arc-Emission may be Harmful to Your Eyes and Skin
•
Wear appropriate welding or cutting mask and clothes to protect your eyes and skin.
•
Use suitable screens or curtains to protect the look-ups from the emission.
•
The welding or cutting sparks may cause fire; make sure that there are no flammable materials nearby in the
working place.
Too Much Noise may be Harmful to Your Hearing
•
Please wear protective gears like earmuffs to protect your ears from loud noises.
•
Warn the look-ups of the harm the noise may cause.
Ask for Professional Help
•
If you have any problems in setting up or operating the tool, please consult this manual first.
•
If you still can’t understand after reading this manual, please contact your supplier or manufacturer to get
professional help.
