MACHINE DESCRIPTION

 

The welding machines are rectifiers adopting the most advanced inverter technology, which can apply in plasma cutting 

system of using pressing air. 

The development of inverter welding equipment benefits from the development of the inverter power supply theory and 

components. Inverter cutting machine I-PLAS25 

. Inverter current firstly commutates the working voltage of 50/60 Hz 

to  Direct  Current.  (DC).  Then  inverter  welding  power  source  utilizes  high-power  component  IGBT  to  transfer  50/60Hz 

frequency up to 20KHz, then reduces the voltage and commutates, and exports high-power voltage via PWM technology, 

resulting  in  the  great  reduce  of  the  main  transformer’s  weight  and  volume  and  the  efficiency  increasing  by  30%.  Arc 

initiation system adopts HF surging theory. It is easy for arc initiation and has function for early feeding air and shutting 

air and its characteristics are arc stable, reliable, portable, and power saving and no electromagnetic noise, high speed of 

cutting, the glabrous shear-out and without polish.   

Plasma  Cutting  Machine  series  can  product  the  stronger,  the  more  concentrated  and  the  more  stable  arc.  The  arc  is 

pressed fiercely by the quickly flowing air and the temperature can be up to 10000-15000 centigrade degree. That forms 

the  electrolyte  estate  and  then  form  strong  plasma  arc.  It  has  the  functions  of  arc  initiation  current,  arc  stop  current, 

welding  current,  basic  value  current,  current  ascending  time,  current  descending  time,  gas  delay  time,  continuous 

adjustment. What’s more, pulse frequency and pulse duty can also be adjusted independently. It has the characteristics 

of automatic control of arc initiation, arc stop and stable arc, which make the best result for shape and inner quality of the 

welding surface. Its exclusive design is especially suitable for bicycle industry. 

Compared with the others cutting machine, the cutting machine series are using the advanced electron circuit to supply 

the  quick  power  and  control  it.  Moreover  they  have  top-ranking  cutting  operation  and  the  extremely  high  transfer 

efficiency.   

The  welding  machine  series  can  easily  design  into  different  cutting  power,  and  the  output  current  is  constant  and 

adjustable as well as excellent operation performance. In common situation its transfer efficiency is above 85%. 

The machine is used widely; it is easier to design into welding machine with different dynamic characteristics. And it can 

weld stainless steel, carbon steel, copper and other color metal, and also can be used for traditional electric welding.   

Thanks  for  purchasing  our  products  and  hope  for  your  precious  advice.  We  will  be  dedicated  to  produce  the  best 

products and offer the best service. 

 

WARNING

 

             

The  machine  is  mainly  used  in  industry.  It  will  produce  radio  wave,  so  the  worker  should  make  fully 

preparation for protection.
