Introduction 

 

 

REHM Operating concept 

The TIGER has an entirely new operating concept; this enables setting up the 
machine  very  simply,  quickly  and  safely.  The  numerous  options  can  all  be 
accessed from this single control knob The settings are all done via a single 
control  knob,  this  can  be  turned  to  select  or  alter  the  parameter  and  then 

pressed to confirm the setting. Using the combination of LED’s and the 3

-digit 

digital display the setting can always be accurately set and reproduced for all 
welding applications. 

 

REHM Noise Reduction System for AC 

The noise is significantly reduced during the welding of Aluminium, by means 
of a patented noise reduction process. 

 

REHM Automatic Frequency Control  

Low stress and long service life combined with optimum economy by means 
of patented Automatic frequency control. 

 

REHM Wave Balance Control 

Improved welding speed by the use of a small diameter electrode, combined 
with optimum penetration.

System 

The processor control system makes this generation of welding units ready to 
face  the  future.  New  process  variants  and  application  developments  can 
simply be retrofitted by means of a software updates. 

 

REHM Dual Wave 

The  Dual  Wave  is  a  newly  developed  welding  process  for  the  welding  of 
Aluminium  or  its  alloys.  This  process  enables  a  much  more  controllable 
welding pool and better welding results. 

 

REHM INTIG-Energy (Intelligent Ignition Energy) 

INTIG-Energy results in an intelligent control sequence for both TIG and stick-
electrode  welding.  The  ignition  process  takes  into  consideration  the  welding 
process  that  has  been  selected  and  is  controlled  via  the  processor.  This 
results  in  a reliable start  every  time with  a  stable arc,  cleaning  the  electrode 
and the workpiece. 

 

REHM ELSA-System (Electronic Stabilised Arc) 

The  ELSA-System:  The  optimum  welding  performance,  even  with  mains 
supply cables up to 100m long is ensured. 

 

REHM EPC (Electronic Power Control) 

The  EPC  continuously  monitors  the  mains  supply  voltage  and  protects  the 
machine under critical situations.
