PREVENTION OF BURNS  

To  protect  your  eyes  and  skin  from  burns  and 
ultraviolet rays: 
- wear dark glasses. Wear suitable clothing, gloves 
and footwear. 
- use  masks  with  closed  sides,  having  lenses  and 
protective glass according to standards (degree of 
protection DIN 10). 
-  warn  people  in  the  vicinity  not  to  look  directly  at 
the arc. 

 
PREVENTION OF FIRE 

Welding produces splashes of molten metal. 
Take the following precautions to prevent fire: 
-  ensure  that  there  is  a  fire  extinguisher  in  the 
welding area. 
-  remove  all  inflammable  material  from  the 
immediate vicinity of the welding area. 
-  cool  the  welded  material  or  let  it  cool  before 
touching it or putting it in contact with combustible 
material 
- never  use  the  machine for  welding  containers  of 
potentially inflammable material.  These  containers 
must  be  completely  cleaned  before  they  are 
welded. 
-  ventilate  the  potentially  inflammable  area  before 
using the machine. 
-  do  not  use  the  machine  in  atmospheres 
containing  high  concentrations  of  powders, 
inflammable gases or combustible vapours. 

 

GENERAL 
CHARACTERISTICS 

This  new  series  of  welding  machines  with 
electronic 

regulation 

controlled 

by 

microprocessor  ,allows  you  to  achieve  excellent 
welding 

quality, 

thanks 

to 

the 

advanced 

technologies  applied.  The  microprocessor  circuit 
controls  and  optimises  the  transfer  of  the  arc 
irrespective  of  the  load  variation  and  of  the 
impedance of the welding cables. 
The  controls  on  the  front  panel  allow  easy 
programming of the welding sequences depending 
on the operating requirements. 
The  inverter  technology  used  has  allowed  the 
following to be obtained: 
- machines with extremely low weight and compact 
dimensions; 
- reduced energy consumption ; 
- excellent dynamic response; 
- very high power factor and yields; 
- better welding characteristics; 
- viewing of the data and of the set functions on the 
display. 
 
The  electronic  components  are  enclosed  in  a 
sturdy  structure  that  is  easy  to  carry  and  cooled 
with forced air by fans with low noise production. 
N.B.  This  welding  machine    is  not  suitable  for 
thawing pipes.
