with

on
the

machine
(~

and
average
source
voltage
(~19

for
any
diameter
of
installed
wire
(Ф0.6...1.2
m).
This
configuration
may
be
not
optimum,
but,
under
condition
of
correct
work,
even
wire
feeding
(without
jerks)
and
correct
connection,
this
"source

FUNCTION
OF

FADE
‐

IN
THE
END
OF
WELDING
This
function
is
designed
for
smooth
filling
of
a
crater,
which
is
formed
in
the
weld
pool
by
the
action
of
electromagnetic
draft
of
the
electric
arc
and
subsequently
becomes
a
source
of
weld
defects.
Release
of
the
torch
button
in
the
end
of
welding
becomes
the
signal
to
start
the
function.
Once
this
happens,
stop
moving
the
torch
and
weld
the
pothole
(which
is
a
crater)
in
the
weld
with
fading

voltage.
Smoothness
of
this
process
can
be
controlled
through
