4 DESCRIPTION OF CONTROL PANEL (Fig. 2)
AE selection key.
Each brief pressure selects the size, adjustable via the
AI knob. The sizes which can be selected are shown by
LEDs AA/AB/AC/AD .
LED AA PRG.
Indicates that the display AL shows the set program
number.
LED AB Thickness
.
The
AL
display shows the recommended thickness based
on the set current and wire speed. Active only in synergic
MIG processes.
LED AC Wire speed
.
Indicates that the display AL shows the wire speed in
welding.
LED AD Current
.
Indicates that the display
AL
shows a welding current.
During welding always shows the measured current; with
the machine at a standstill, if AG is OFF, shows the set
current.
LED AF - Globular position.
May not be selected . Active in synergic MIG process.
When lit, this signals that the pair of values chosen for
welding may give unstable arcs and splatters.
LED AG - Hold.
May not be selected. It signals that the values shown on
the displays AL and AM (normally Amperes and Volts) are
those used during last welding. Activated at the end of
each welding session.
LED AH - Voltage.
In all welding processes, it indicates that the display AM
shows the re-set welding voltage or, if in combination with
LED
AG
lit, the last measured voltage.
Knob AI.
The following values are set: welding current A , wire speed
( ), thickness ( ), program number
PRG
. In the service
functions the following are selected: TRG, SP, HSA, CrA,
PrF, PoF, Acc, bb, L, Dp, PPF, Ito, Fac .
In MIG synergic processes when a value is adjusted the
other values are adjusted as well. All these values are
shown on the display
AL
.
Knob AN.
The following sizes are set:
In synergic MIG the arc length, in conventional MIG the
welding voltage.
Inside the service menu, according to the value set
by knob AI it selects the set value, the activation or
desactivation of the same, or an additional selection to be
made inside the fuction.
