  SAFETY 

INTRODUCTION: 

WE LEARN BY EXPERIENCE Learning safety through personal experience, like a child 
touching a hot stove is harmful. wasteful. and unwise. Let the experience of others 
teach you. 
 

SAFE PRACTICES DEVELOPED FROM EXPERIENCE 

in the use of welding and cutting are

 

described in this manual. Research, develop-

ment, and field experience have evolved reliable equipment and safe installation, 
operation, and servicing practices. Accidents occur when equipment is improperly 
used or maintained The reason for these sole practices may not always be given. 
Some are based on common sense, others may require technical volumes to ex-
plain, it is wiser to follow the rules. 
 

READ AND UNDERSTAND THESE SAFE PRACTICES 

before attempting to install, operate or service the equipment. Comply with these 
procedures as applicable to the particular equipment used and their instruction 
manuals, for personal safety and for the safety of others. 
 

FAILURE TO OBSERVE THESE SAFE PRACTICES  

may cause serious injury or death. When safety becomes a habit, the equipment 
can be used with confidence. 
 

GENERAL: 

The plasma cutting machine is simple and safe to operate under normal circum-
stances. If the unit is to be used under unusual circumstances, e.g. in wet or damp 
conditions, on boats or oil rigs, or in an elevated position.  Then extra thought must 
be given to any possible hazard introduced by the situation. 
 

ELECTRICAL: 

A. DO NOT operate the machine with any of the panels removed. 
B. DO NOT attempt any repairs unless you are a competent electrician. 
C. Ensure that the machine is connected to the correct supply voltage through the 
recommended fuse. 
 

NB: This unit must be earthed. 

D. DO NOT dismantle the protection nozzle from the torch without first switching off 
the machine. 
 

ELECTRIC SHOCK 

Either AC or’ DC voltages associated with the cutting environment can cause 
severe burns to the body or fatal shock. Severity of electrical shock is deter-
mined by the path and amount of current through the body.
