change.
This
is
a
very
important
condition
for
the
user
when
he/she
needs
to
estimate
the
exact
change
of
heat
input
into
the
weld
pool,
for
example,
when
he/she
compares
this
current
with
another
base
current
without
the
pulsed
welding
mode.
These
parameters
are
set
differently
in
different
situations
in
accordance
with
welding
operator's
requirements.
See
paragraph
6.1
for
sequence
of
changing
the
value
of
any
function
in
the
current
welding
mode.
5. SEMIAUTOMATIC
METAL
INERT/ACTIVE
GAS
WELDING
(MIG/MAG)
The
machine
can
serve
as
a
semiautomatic
welding
source.
For
this
purpose,
it
provides
the
required
current
‐
voltage
curve
on
the
output
of
power
terminals
in
case
of
switching
to
this
mode.
Any
independent
feeding
unit,
which
is
operated
by
specific
supply
voltage
of
the
in
‐
built
motor,
can
serve
as
the
external
wire
‐
feeding
machine.
In
order
to
do
that,
it
must
have
its
own
supply
source
or
be
supplied
by
the
source
voltage
(this
option
is
less
desirable,
because
such
systems
rarely
provide
good
and
stable
wire
feeding).
ATTENTION:
In
the
most
general
case,
carbon
dioxide
"СО2"
is
used
as
shielding
gas
for
welding
of
iron,
and
aluminium
is
welded
only
using
inert
gases,
such
as
argon
"Ar"
and
sometimes
expensive
helium
"He".
For
stainless
and
high
‐
alloy
steels,
mixtures
with
different
ratios
are
often
used,
such
as
"80%Ar+20%CO2".
Other
gases
can
only
be
used
upon
approval
of
the
equipment
manufacturer.
Procedure
for
preparation
to
welding
with
solid
wire:
‐
insert
the
"earth"
cable
into
the
source
socket
B
"
‐
"
;
‐
connect
the
"earth"
cable
to
the
work
piece;
‐
connect
one
end
the
premanufactured
power
jumper
with
cable
cross
‐
section
of
at
least
16
mm
2
to
the
source
socket
А
"+",
and
the
other
end
to
power
terminal
of
the
wire
‐
feeding
machine,
which
is
case
‐
specific,
so
there
is
no
point
in
listing
all
possible
options;
‐
connect
the
semiautomatic
welding
torch
to
the
wire
‐
feeding
machine;
