7. Power Switch: It turns ON / OFF the input power
to the machine.
8. Input cable: This machine is provided with a
plugged input cord. Connect it to the mains.
9. Fan: This machine has a F.A.N. (Fan As Needed)
circuitry inside: the fan is automatically turned ON
or OFF. This feature reduces the amount of dirt
which can be drawn inside the machine and
reduces power consumption. The F.A.N. operates
in different modes, it depends by the selected weld:
• Stick mode: When the machine is turned ON the
fan will turn ON. The fan will continue to run when-
ever the machine is welding. If the machine doesnʼt
weld for more than five minutes, the fan will turn
OFF.
• TIG modes: When the machine is turned ON the
fan is OFF. The fan will turn ON only when a weld
is started and it will continue to run whenever the
machine is welding. If the machine doesnʼt weld for
more than five minutes, the fan will turn OFF.

OPERATION
AUTO ADAPTIVE ARC FORCE
(WITH STICK WELDING)
The Auto Adaptive Arc Force function is activated dur-
ing stick welding. This function increases temporary
the output current, used to clear intermittent connec-
tions between the electrode and the weld puddle that
occur during stick welding.
This is an active control feature that guarantees the
best arrangement between the arc stability and spat-
ter presence. The feature "Auto Adaptive Arc Force"
has instead of a fixed or manual regulation, an auto-
matic and multilevel setting: its intensity depends by
the output voltage and is controlled by the micro-
processor.
The control determines the amount of current to apply
to break the metal drop that is being transferred from
the electrode to the workpiece to guarantee the arc
stability, but not too high to minimize spatter around
the welding puddle. That means:
• Electrode / workpiece sticking prevention, also with
low current values.
• Spatters reduction.
The welding operations are simplified and the welded
joints looks better, also if not brushed after the weld-
ing.
This feature is available in both the Soft Stick and
Crisp Stick operating modes. The Crisp Stick feature
also increases the Hot Start action, facilitating the arc
striking.
With the Stick welding are also enabled the following
features:
• Hot Start: This is a temporary increase in the initial
7
• Anti-Sticking: This is a function that decreases the

welding current. This helps ignite the arc
quickly and reliably.
output current of the machine to a low
level when the operator makes an
error and sticks the electrode to the
work piece. This decrease in current
allows the operator to remove the
electrode from the electrode holder
without creating large sparks that can
damage the electrode holder.
