M1
The 0 (zero) value corresponds to the manufacturer preset
impedance.
By means of knob M2 it is possible to increase (positive
values) or reduce (negative values) it in a -9.9 ÷ +9.9 range.
Knob M2
The values selected through key T2 are adjusted
according to the process type selected by means
of this knob
In synergic MIG/MAG welding processes, when led L4 is
on (welding voltage), via this knob the selection switches
automatically to led L5 (arc length).
Display D2
In all welding processes, it numerically displays the selec-
tions made via the selection key T2 and adjusted via the
knob M2.
Led L7 Globular position
In MIG/MAG synergic processes, this signals that the
pair of current and voltage values chosen for welding
may give unstable arcs and splatters.
Led L8 Hold
It lights automatically at the end of the welding process
to indicate that displays D1 and D2 show the two most
recent current and voltage measured values.
Led L9 Safety
Signals the lock function for some keys. The operator
may adjust only the welding parameters included in the
control panel. To activate the function, press the T5 key
fi rst then, while holding it down, briefl y press the T2 key.

The led L9 lights to indicate that the function is active. To
exit, press similarly keys T5 and T2.
Key T4 Wire test
It allows the progressive wire feed up to 8m/min
with no voltage present in the torch and no gas
fl ow.
Key T3 Test gas
hen this key is pressed, the gas fl ows out for 3
seconds. f pressed again the fl ow stops.
6.2 SETTINGS PANEL (FIG. 14).
Allows a quick access to the welding machine menu and
to the additional functions that are displayed and imme-
diately available. It consists of a matrix display D3 that
shows all information re uired to program the surfi ng keys
(T10, T11, T12 and T13) used to surf inside the menu; it
also consists of function keys (T5, T6, T7, T8 and T9) that
allow access to the different menus that make up the fi rm
ware and a series of leds that signal the type of process
in operation (L10, L11 and L12) and a few additional func-
tions (L13L14 and L15).

When the welding ma-
chine starts, the display
D3 shows for about 5s, a
few information about
machine status (see par.
7.4 Information menu)
including the fi rmware
version.
