This is an active control feature that guarantees the
best arrangement between the arc stability and
spatter presence. The feature "Auto Adaptive Arc
Force" has instead of a fixed or manual regulation,
an automatic and multilevel setting: its intensity
depends by the output voltage and it is calculated in
real time by the microprocessor where are also
mapped the Arc Force levels. The control measure
in each instant the output voltage and it determines
the amount of the peak of current to apply; that
value is enough to breaks the metal drop that is
being transferred from the electrode to the
workpiece as to guarantee the arc stability, but not
too high to avoid spatters around the welding
puddle. That means:

Electrode / workpiece sticking prevention, also
with low current values.

Spatters reduction.
