ARC
FORCE
FUNCTION
Advantages:
‐
enhanced
short
‐
arc
welding
stability;
‐
better
transfer
of
metal
drops
into
the
weld
pool;
‐
better
arc
striking;
‐
reduced
risk
of
electrode
sticking;
however,
it
is
not
the
Anti
‐
Stick
function,
which
will
be
explained
in
the
next
paragraph;
‐
manual
adjustment;
allows
setting
the
function
level
to
minimum
value,
thus
reducing
power
consumption
(although
insignificantly),
as
well
as
heat
input
concentration
when
welding
thin
metal
pieces.
This
reduces
the
risk
of
burn
‐
through,
but
also
reduces
stability
of
short
arc
burning
(the
machine
becomes
similar
to
a
transformer
source).
The
function
can
also
be
increased
to
maximum
value
for
even
better
stability
of
short
‐
arc
burning,
but
this
requires
for
better
supply
mains
and
increases
the
risk
of
work
piece
burn
‐
through.
The
result
is
achieved
by
the
following
means:
Due
to
reduction
of
arc
voltage
below
the
minimum
permissible
voltage
of
stable
arc
burning,
arc
current
increases
by
the
default
value
of
+40%.
In
the
additional
settings
you
can
change
both
Arc
Force
magnitude
[Ar.F]
and
trigger
level
of
this
function
[u.AF].
Do
not
set
Arc
Force
magnitude
and
trigger
level
to
unnecessarily
high
value,
because
at
high
limit
values,
especially
during
welding
with
thin
electrodes
less
than
Ф
3.2
mm
in
diameter,
affects
actuation
of
Anti
‐
Stick
function,
which
will
be
explained
in
the
next
paragraph.
See
paragraph
6.1
for
sequence
of
changing
the
value
of
any
function
in
the
current
welding
mode.
