3.  Cut off the curved or damaged end of welding wire and lead it through the 

inlet liner 

E3,

 and the roll into the liner inside the EURO torch connector 

(about 5 cm). Make sure, that you use the suitable groove. 

4.  Put the pressure arm 

E2

 down in that way, that the teeth or the gear fit and 

fix it by setting the lever 

E1

 into vertical position. 

5.  Adjust  the  pressure  nut  that  way  that  it  provides  constant  movement  of 

wire but it does not deform wire. By pressing the button 

A10

, placed in the 

space  of  the wire feeder, turn on  the  motor of the feeder. The adjusting 
screw is located under the plastic screws 

E1

6.  The spool brake is set by the manufacturer. If necessary, the brake can be 

adjusted  by  a  screw 

D1

  so  that  while  stopping  the  feed,  spool  will  be 

stopped on time (it will avoid excessive release of wire). However, too tight 
brake  needlessly  strains  the  feeding  mechanism  and  thus  slippage  may 
occur in the wire rolls.

ADJUSTING PRESSURE FORCE OF FEED ROLLS  

Important  thing  for  reliable  operation  of  the  feeding  mechanism  is  the  size  of 
pressure force of feed rolls. 

The amount of force depends on the type of welding wire, for aluminum or tube 
wire, we choose a smaller pressure force. 

If  the  pressure  force  is  too  small,  slippage  may  occur  and  thus  irregular  wire 
feeding speed.  

If  the  pressure  force  is  too  high,  it  will  lead  to  increased  mechanical  wear  of 
bearings and it can damage the machine. Before  putting into operation,  clean 
the rolls from preservative oil.
