falling into the machine inside when replacing the components.

Pay attention to the following when discarding the machine:

Burning the plastic parts such as the front panel may produce poisonous gas.

Dispose it as industrial waste.

cutting

Burning the electrolytic capacitors in the main circuit or on the PCBs may cause an explosion.

Smoke-may be harmful to your health!

Keep your head away from the smoke to avoid inhalation of waste gas

in cutting.

Keep the working environment well ventilated with exhaust or ventilation

equipment when .cutting

Arc radiation-may hurt your eyes and burn your skin!

Use proper mask and wear protective clothing to protect your eyes and

body.

Use proper mask or curtain to protect onlooker from being injured.

Magnetic field can make cardiac pacemaker a bit wonky!

Stay away from the power source to reduce the affect of magnetic filed.

Improper use and operation may result in a fire or an explosion!

Cutting spark may result in a fire, so please make ensure there are no

inflammables near the position, and pay attention to fire safety.cutting

Ensure there is fire extinguisher nearby, and make sure someone has

been trained to operate the fire extinguisher.

Do not weld closed container.

Do not use this machine for pipe thawing.

Hot workpiece can cause severe scald!

Do not touch hot workpiece with bare hands.

Cool the torch for a while after continuously working.cutting

Excessive noise does great harm to people’s hearing!

Wear ear covers or other hearing protectors when .cutting

Give warning to onlooker that noise may be potentially hazardous to

hearing.

Moving parts may injure your body!

Please keep away from moving parts (like fan).

Each door, panel, cover, baffle plate, and protective device the like

should be closed and located correctly.

Seek professional support when trouble strikes!

When trouble strikes in installation and operation, please inspect

according to related contents in this manual.

If you still cannot understand fully, or you still cannot solve the problem,

People with cardiac pacemaker should consult the doctor before carrying

out .cutting

please contact the dealer or the service center of JASIC to obtain

1.5 Functions and characteristics of the cutting machine

CUT series are inverter cutting machines made by our company with advanced inverter technology.

They are more mature products with stable performance. With PWM technology and high power

component IGBT, it inverts the DC voltage, which is rectified from 50Hz/60Hz

input AC voltage, to 30K~100KHz AC high voltage. Then the voltage is dropped and rectified to

output the high power DC power supply for cutting. The machine adopts switching power supply

inverter technology, greatly reducing the volume and weight of the cutter, and obviously enhancing

the conversion efficiency by 30%.

Features of CUT series

Economic and practical by adopting compressed air as the plasma gas source. The cutting

speed has increased by 1.8 times when compared with oxyacetylene cutting.

It can cut thick steel plate conveniently and quickly.

It is easy to ignite arc, and post-flow function is available.

It has a wide range of use, especially for cutting stainless steel, copper, cast iron and

aluminum, etc.

With simple operation and high cutting speed, smooth cutting surface can be obtained, and

polishing is unnecessary.

It adopts HF arc ignition mode.
