ANTI
‐
STICK
FUNCTION
During
initial
arc
striking,
the
electrode
can
stick
or
be
tacked
to
the
work
piece.
Many
functions
of
the
machine
resist
this
occurrence,
but
it
is
possible
nevertheless,
first
leading
to
overheating
and
eventually
to
damage
of
the
electrode.
In
such
a
case,
this
machine
actuates
the
built
‐
in
Anti
‐
Stick
function,
which
is
constantly
operating
in
the
MMA
mode.
Within
0.6...0.8
s
after
detection
of
this
condition,
this
function
reduces
arc
current.
In
addition,
this
function
helps
the
welding
operator
to
separate
(detach)
the
electrode
from
the
work
piece
without
risk
to
burn
his
eyes
with
accidental
arc
striking.
Once
the
electrode
is
separated
from
the
work
piece,
the
process
of
welding
can
be
readily
resumed.
3.5
FUNCTION
OF
SLOPE
ADJUSTMENT
FOR
A
CURRENT
‐
VOLTAGE
CURVE
This
function
is
primarily
designed
for
convenient
welding
using
electrodes
with
different
types
of
coating.
By
default,
current
‐
voltage
curve
slope
[CVS]
is
set
to
1.4V/A,
which
corresponds
to
the
most
commonly
used
electrodes
with
rutile
coating
(
АНО‐
21,
М
Р
‐
3).
For
more
convenient
work
with
basic
‐
coated
electrodes
(
УОНИ‐
13/45,
Л
КЗ
‐
70),
it
is
recommended,
although
not
required,
to
set
the
slope
[CVS]
to
1.0V/A.
On
the
other
hand,
cellulose
electrodes
(ЦЦ
‐
1,
В
СЦ
‐
4А)
even
require
for
setting
the
slope
[CVS]
to
0.2...0.6V/A,
and
sometimes
it
is
also
necessary
to
rise
trigger
level
of
the
Arc
Force
Function
[u.AF]
up
to
18
V.
See
paragraph
6.1
for
sequence
of
changing
the
value
of
any
function
in
the
current
welding
mode.
3.6
SHORT
ARC
WELDING
FUNCTION
This
function
is
especially
important
for
overhead
welding,
when
very
long
arc
is
undesirable.
For
this
purpose,
the
machine
provides
the
possibility
to
set
the
Short
Arc
function
[Sh.A]
to
"On"
position.
By
default,
it
is
set
to
"OFF"
position.
See
paragraph
6.1
for
sequence
of
changing
the
value
of
any
function
in
the
current
welding
mode.
3.7
FUNCTION
OF
AN
OPEN
‐
CIRCUIT
VOLTAGE
REDUCTION
UNIT
When
performing
welding
works
in
vessels,
tanks
and
applications
requiring
for
enhanced
electric
safety
system,
one
can
enable
the
function
of
open
‐
circuit
voltage
reduction.
In
0.1
s
after
the
electrode
is
detached
from
the
work
piece,
voltage
on
the
source
terminals
drops
to
safe
level
below
12
V.
To
enable
this
function,
an
open
‐
circuit
voltage
reduction
unit
[BSn]
is
required.
This
unit
is
envisaged
in
this
equipment
model,
but
is
set
to
"OFF"
position
by
default,
i.e.
disabled,
since
it
is
known,
that
enabling
of
any
function
of
this
kind
