9.1 SERVICE MENU

Our machines have a Service Menu and it is reachable by a combination of buttons. This menu allows to 

modify some parameters to improve and/or customize Your machine depending on Your needs.

9.2 ENTERING IN SERVICE MENU

 + 

In the starting phase of the machine, it is necessary to push both wire charge (PU3) button and “2S/4S/

MMA” (PU1) button until the “MENU SERV” appears on display to enter the service menu.

By release the two buttons You will see the first changeable welding parameter.

9.3 NAVIGATE IN SERVICE MENU

To scroll the service menu it will be enough to rotate the voltage setting knob (EN2) and the parameter 

with its default value will be showed.

To modify this parameter value You can only  turn wire speed/current setting knob (EN1).

After setting  the parameter value You will have to push “2S/4S/MMA2” button to memorize it (PU1).

Pushing the button You will see on the display, where there is the parameter value, the script SAV  for 

few seconds to indicate that the parameter has been saved.

9.4 MENU LEGENDA

The settable parameters in service menu are different depending on MIG/MAG or MMA mode.

In case of MIG/MAG mode, the parameters are:

• 

Pre-gas time:

 “PRE” script is visualized. It is showed in seconds. Default value is 0,1s.Changeable 

interval (0,1-5) seconds.

• 

Post-gas time:

 “POST” script is visualized. It is showed in seconds. Default value is 0,1s.

Changeable interval (0,1-5) seconds

• 

Hot start:

 “t C” script is visualized. It indicates the trigger current expressed in Ampere. Default value 

is 370A. Changeable interval (150-400) Ampere.

• 

Hot start time:

 “TCS” script is visualized. It indicates the time of trigger current. It is expressed in 

milliseconds. Default value is 8ms. Changeable interval (1-40) milliseconds.

• 

Trigger voltage: 

“TV” script is visualized. It indicates the trigger voltage expressed in Volt. Default 

value is 18V. Changeable interval (5-30) volt.

• 

Motor ramp:

 “M r” script is visualized. It indicates motor speed variation from stopped to reference 

speed. Default value is 50. Changeable interval (1-100).

• 

Detach current:

 “d C” script is visualized. It indicates the set current for drop detach at the end of 

welding. It is expressed in Ampere. Default value is 400A. Changeable interval (370-420).

• 

Detach current time:

 “dCS” script is visualized. It indicates the time needed for detach current. It is 

expressed in milliseconds. Default value is 4ms. Changeable interval (1-10) milliseconds.

• 

Minimum welding current:

 “M C” script visualized. It indicates the minimum settable current. It is 

expressed in ampere. Default value is 15A. Changeable interval (5-50) ampere.

• 

Water cooling unit mode setting:

 this parameter appears only if the machine is equipped by  water 

cooling unit inside the torch. Starting the unit with on button, it can work in two modes: “ON” mode
