SET mode button with a control light for selection of function parameter.

 After pushing this button we enter 

mode, 

which 

allows 

us 

to 

change 

the 

values 

of 

individual 

functions.

5. If the button is activated, the LED control light 

will go on. 

5.

 

Selector for setting of welding voltage and switching between functions in the SET mode.  

6.

 

Controls showing the display mode. 

7.

 

Controls showing the value unit on the display. 

8.

 

Selector for setting of feed speed and values in the SET mode. 

9.

 

Gas  test button.

  By  pushing  this  button  countdown  for  setting  of gas  flow will  start. The  time  is shown  on 

display 13 (pic. 5). The countdown can be terminated by repeatedly pushing the button 9 (pic. 5) or the weld-
ing torch button.  

10.

 

Wire  loading  button. 

After  pushing  button  10  the  loading  of  wire  is  started.  The  loading  process  can  be 

stopped by pushing button 10 again or by the welding torch button. 

11.

 

The SAVE button.

 This button allows saving of the set parameters into pre-selections PrG1 to PrG20. 

12.

 

PROG  button  with  control.

  This  button  serves  for  programs  display.  By  pushing  this  button  we  enter  the 

program  selection  mode.  The  programs  are  chosen  by  selector  8.  The  chosen  program  is  confirmed  by  re-
peatedly pushing button 12 (pic. 5). 

13.

 

Display showing the wire feed speed, welding voltage/value and the functions status.

 During welding the 

display shows the welding voltage value. After termination of welding this value remains on the display for 
approximately three seconds.  
In an idle state the wire feed speed is  displayed. During setting in the SET mode the status of the selected 
function is displayed – either off or the selected function value.  

14.

 

Display  showing  voltage  value  or  the  selected  function  type.

  During  welding  and  three  seconds  after  its 

termination  the  display  shows  the  welding  voltage  value.  After  welding  termination,  the  value  remains  on 
display for another three seconds. In the SET mode the abbreviation of the function currently being set is dis-
played.  

15.

 

The temperature indicator light.

 The temperature indicator signals the machine overheating.  

16.

 

The input voltage indicator.

 The indicator light is on when the input voltage is out of range. 

17.

 

The indicator inverter ON.

 The indicator is on when the output part of the machine is running.

 

 

 

Function SYNERGIC 

 
Activation of synergic function 

Press button PROG (pos. 12) and by switch 8 choose one of synergic programs. 

 
Description of synergic programs is on page 82.
