Product Overview

2

CUT25 is a plasma cutting machine model developed from 
the original CUT series plasma cutting machines. It inherits 
the  mature  and  stable  inverter  technology  of  CUT  series: 
With  PWM  technology  and  high-power  MOSFET  switching 
devices, it converts the DC voltage, which is rectified from 
50Hz/60Hz  input  AC  voltage,  to  100KHz  AC  high  voltage. 
Then, the voltage is dropped and rectified, providing a high-
power DC cutting is output.

The  CUT  series  uses  a  non-HF  arc  ignition  with  pilot  arc. 
This  reduce  EMI  emissions  during  the  arc  start.  Therefore, 
non-HF  arc  ignition  with  pilot  arc  should  be  used  when 
higher  requirement  on  electromagnetic  environment  is 
needed,  e.g.  in  CNC  cutting.The  CUT25  is  designed  for 
such  high-end  application.  In  addition,  CUT25  adopts  a 
single  PCB  structure.  An  external  air  source  connection  is 
unnecessary,  since  it  is  equipped  with  an  internal  air 
compressor.  Both  contact  and  non-contact  mode  is 
available  for  successful  arc  ignition,  and  the  3s  pilot  arc 
time auto control inside the machine e

ectively reduces the 

wear of torch nozzle. The machine has such advantages as 
simple  internal  structure,  small  size,  easy  to  ignite  arc  and 
convenient to use.

Product functions

Internal  air  compressor  is  equipped,  and  external  air 

source connection is unnecessary.

Fixed current output

Product performance characteristics

Economical  and  practical  by  using  compressed  air  as  the 

plasma gas source. 

The cutting speed is increased by 1.8 times when compared 

with oxy-acetylene cutting.

It can cut thin steel plate conveniently and quickly.

Easy  to  ignite  arc,  pre-flow  and  post-flow  function 

available.

It has a wide range of use, especially for cutting stainless 

steel, copper, cast iron and aluminum, etc.

Simple operation 

Excellent cut quality 

Both  contact  and  non-contact  mode  is  available  for 

successful arc ignition.
