PRODUCT DETAILS AND APPLICATION

 

 

 

Advanced digital control mode  

The Jasic plasma cutting machines JP-61 and JP-81 incorporate MUC intelligent digital control technology,   
and all its major functions are performed using software controls. The digital control plasma cutting machine 
offers many improvements in function and performance when compared with the traditional type plasma 
cutting machines.  
With PWM technology and high power component IGBTs, it inverts the DC voltage, which is rectified from 
50Hz/60Hz input AC voltage, to 30K~50kHz AC high voltage. The voltage is dropped and rectified to output the 
DC power supply for cutting. This inverter technology provides a machine which is smaller and much less 
weight than the traditional style machine. The technology provides a high efficiency unit and a switching     
frequency which is outside the audible range.  

 

Good consistency and stable performance  

In traditional machines consistency and performance is often governed by the tolerances of the components 
used in manufacture and environmental such as temperature and humidity. In some cases the same machine 
brand and type can vary in performance due to tolerance differences. One of the characteristics of digital   
control is that it is not sensitive to the change of these parameters. The performance of cutting machine will 
not be affected by the change of the parameters of individual parts. Therefore, the consistency and stability  
of performance of the digital control cutter is better than that of traditional cutter.  

 

Powerful cutting performance  

The Jasic 61 and 81 plasma machines provide economical cutting of metals using compressed air as the      
plasma gas source. The cutting speed is 1.8 times when compared with oxy acetylene cutting. These machines 
can cut steel, stainless steel, copper, cast iron and aluminium easily and quickly. The arc is an easy to ignite  
arc and uses a non HF arc ignition mode. There is a postflow function operates to cool the torch after cutting. 
The simple operation and high cutting speed, smooth cutting surface make the plasma process and excellent 
cutting method.  
 

Product features 

The Cut 61 and 81 cutting current can be accurately preset with seamless adjustment which is achieved  
through the preset current function. Thus, the machine can be used to cut work pieces of different  
thicknesses. 
Low current is used when cutting thin plate and high current is used when cutting thick plate to ensure  
good cutting quality and energy savings. 
With protection function of over/under-voltage, thermal overheating and low gas pressure inside the  
machine; gas-check and 2T/4T function. 
Also as standard is the automated interface with remote start/stop, arc established ok to move signal  
and a divided arc voltage output for a torch height controller making it suitable to connect to most CNC  
cutting tables when fitted with a 180° cutting torch. 
 

Application 

The non HF pilot arc of the Cut 61 and 81 combined with the PT100 plasma torch offers excellent arc  
ignition which can cut through rusty and painted metals along with ferrous and non ferrous easily which  
can effectively prolong the lifespan of the electrode and nozzle of the plasma cutting torch. 
It can be widely used in various industries involving metal cutting such as boiler and pressure vessel  
manufacturing, chemical container manufacturing, power plant installation and construction industry,  
metallurgy, chemical engineering, aerospace, automobile and engineering vehicles manufacturing and  
construction etc.
