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.

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.
