OF
CONTROLS
The
TIME
RANGE
switch
provides
the
WELD
TIME
control
with
two
ranges.
When
the
TIME
RANGE
switch
is
in
the
upper
position,
a
range
of
.2
to
2.5
seconds
is
available
to
the
WELD
TIME
control.
When
in
the
lower
position,
a
range
of
2.5
to
5
seconds
is
available.
The
SPOT
TEST
button
provides
a
means
of
measuring
the
length
of
wire
that
will
feed
during
a
spot
weld
cycle
without
electrically
energizing
the electrode
wire.
To
operate,
first
place
the
SPOT
TEST
switch
in
the
SPOT
TEST
position
and
then
depress
the
switch
on
the
gun.
Wire
will
now
feed
for
the
amount
of
time
set
on
the
WELD
TIME
control.
~imperative
that
the
SPOT
TEST~ch
be
placed
in
the
SPOT
TEST
position
first
before
depressing
the
gun
switch.
Failure
to
comply
with
this
procedure
will
result
in
an
electrically
hot
electrode
wire
which
could
î‚•
cause
a
severe
or
fatal
shock
to
the
body.
The
INCH
SPEED
control
determines
the
rate at
which
the
electrode
wire
will
feed
from
the
moment
the
gun
switch
is
depressed
until
the
wire
initially
touches
the
workpiece.
The
INCH
SPEED
controlî‚’s
variable
rate
will
be
the
same
as
the
rate
that
can
be obtained
by
the
WIRE
SPEED
control
on
the
control/feeder.
~he
elect
rode
wire
touch
es
the
wo
rkp
iece,
the
INCH
SPEED
control
becomes
inoperative
and
the
rate
that
the
wire
feeds
is
determined
by
the
setting
of
the
WIRE
SPEED
control
on
the
control/feeder.
î‚•
Once
the
WELD
TIME
control
becomes
functional,
.
the
gun
switch
may
be
released.
The
CS-2
unit
goes
through
the
complete
weld
cycle
regardless
of
the
position
of
the
gun
switch.
If
the
gun
switch
is
released
prior
to
the
WELD
TIME
control
becoming
functional,
the
CS-2
stops
and
re-sets
to
the
beginning
of
the
weld
sequence
(start
of
pre-flow).
3-5.
BURNBACK
TIME
CONTROL
The
purpose
of
the
BURNBACK
TIME
control
is
to
prevent
the
electrode
wire
from
sticking
to
the
workpiece
after
the
weld
time
is
complete.
The
BURNBACK
TIME
control
prevents
this
by
providing
an
adjustable
time
period
(up
to
a
maximum
of
.25
second)
that
the
electrode
wire
remains
electrically
hot
after
the
wire
has
stopped
feeding.
If
the
welding
wire
freezes
in
the
weld
puddle,
the
BURN-
BACK
TIME
control
setting
should
be
increased,
thereby
keeping
the
welding
wire
electrically
hot
for
a
longer
period
of
time
after
wire
feed
has
stopped.
This
in
turn
will
permit
the electrode
wire
to
burn
free
of
the
weld
puddle.
If
the
welding
wire
freezes
in
the
contact
tube,
the
BURNBACK
TIME
control
setting
should
be
decreased.
Decreasing
the
setting
will
permit
the
welding
wire
to
be
electrically
hot
for
a
lesser
period
of
time
thus
permitting
the
welding
wire
to
stick
Out
of
the
contact
tube
at
the
conclusion
of
the
weld.
3-6.
PRE-FLOW
&
POST-FLOW
CONTROLS
The
PRE-FLOW
and
POST-FLOW
controls,
located
on
the
rear
of
the
CS-2
unit,
provide
a
means
of
adjusting
the
period
of
time
that
shielding
gas
will
flow
before
the
weld
cycle
begins
and
after
it
has
been
completed.
34.
WELD
TIME
CONTROL
&
TIME
RANGE
SWITCH
The
WELD
TIME
control
determines
the
period
of
time
that
the
electrode
wire
is
allowed
to
feed.
The
WELD
TIME
control
begins
to
time
out
as
soon
as
the
electrode
wire
touches
the
workpiece.
The
pre-flow
time
is
adjustable
from
1/10
to
2-1/2
seconds
and
will
begin
to
be
timed
out
as
soon
as
the
gun
switch
is
closed.
The
post-flow
time
is
adjustable
from
1/10
to
10
seconds
and
will
begin
to
be
timed
out
as
soon
as
the
BURNBACK
TIME
has
elapsed.
