DESCRIPTION

FUNCTION

1

VIEW DISPLAY LEFT

It shows the welding voltage set while during welding process visualizes 

the voltage measured by the machine.

It’s also showed, when modified, the tacking time set.
On MMA mode it shows the welding voltage measured by the machine.
It’s  also  showed,  when  modified,  the  reference  parameter  of  the  “Hot 

Start” percentage.

2

VIEW DISPLAY RIGHT

It shows the wire speed set while during welding process visualizes the 

current measured by the machine.

It’s also showed, when modified, the inductance parameter.
On MMA mode it shows the reference current set while during welding 
process visualizes the current measured by the machine. It’s also showed, 
when modified, the reference parameter of the “Arc Force” percentage.
Both displays contribute to errors viewing.

3

(PU3)

WIRE LOADING BUTTON

It allows the manual wire loading at the speed set before welding process, 
on the display appears “WIRE LOAD”.

4

(PU1)

2S/4S/MMA 

COMMUTATION BUTTON

On MIG mode it allows to set the functioning in 2 or 4 strokes. During 
2 strokes mode (2s) the machine welds for all the time long when torch 

button is pushed.

During 4 strokes mode (4s) a first pressure on torch button at start, the 

second pressure to stop.
Pushing once again the button it changes in MMA mode.

5

(PU2)

COOLING UNIT ON/OFF 

BUTTON

On MIG/MAG mode it allows to switch on or off the cooling unit in case 
of water cooled torches used.

6

EN2

WELDING VOLTAGE KNOB

It’s operative only on MIG mode.

7

EN1

WELDING CURRENT / 

WIRE SPEED SETTING 

KNOB

On MIG/MAG mode it allow to set the material deposit speed (wire 
speed); on MMA mode it allows to set the welding current.

8

POT4

TACKING/HOT START 

CURRENT TIME 

REGULATION HANDLE

On MIG mode it allows to set the welding time. On MMA mode it allows 
to set the percentage of current increase, compared to welding current, 
with whom the welding machine can force at the trigger of the arc (HOT 
START). 

9

POT3

INDUCTANCE/ARC FORCE 
CURRENT SETTING KNOB

On MIG/MAG mode it allows to modify the inductance to obtain a 
sharper (low values) or softer arc (high values). On MMA mode it allows 
to set the percentage of current increase, compared to welding current, 
with whom the welding machine can force to maintain the arc well 
trigged (ARC FORCE).
