INTRODUCTION 

 

THIS DEVICE must be used exclusively for cutting on any electrically conductive material (metals 
and alloys).  
PLASMA cutting takes place due to the high temperature generated by a concentrated electric arc, 
and thus highly dangerous situations may arise; it is therefore essential to pay the utmost attention 
to the chapter entitled SAFETY PRECAUTIONS.  
This manual must be kept carefully in a place familiar to everyone involved in using the machine. It 
must be consulted whenever doubts arise and be kept for the entire life-span of the machine; it will 
also be used for ordering replacement parts.  
 
 
 

NOTE 

 

Only use original spares.  
Always replace any damaged part of the unit or torch with original material.  
Do not use any torches other than the original one.  
Do not let the unit work without covers. This would be dangerous for operator and for those who are 
surrounding the work area and would prevent the unit from cooling efficiently.
