DESCRIPTION
This
weld
control
has
silicon
control
rectifiers,
diodes,
and
transistors
in
the
timing,
speed,
and
brake
circuits
for
pre
cision
control
and
dependable
service.
The
printed
Circuit
board
can
be
easily
replaced
as
a
unit
if
required.
This
weld
control
is
designed
for
use
with
a
constant
potential
welding
power
source.
This
weld
control
includes
controls
for
gas
metal-arc
spot
welding.
A
simple
jumper
relocation
Converts
control from
one
process
to
the
other.
Ten-foot
interconnecting
cords and
gas
hose
are included.

that
need
special emphasis
to
obtain
the
most

operation
of
the
equipment.
A
proper
installation site should
be
selected
for
the weld
control
if
the unit
is
to
provide
dependable
service,
and
re
main
relatively
maintenance free.
A
proper
installation site
permits
freedom of
air

3-11. RUN
IN
CONTROL
(Figure
3-11
The RUN
IN
Control
provides
a means
of
determining
the
rate at
which
welding
wire
will
be fed into the weld
prior
to
arc
initiation.
After
arc
initiation,
the wire
feed
speed
is
governed
by
the
WELD
CURRENT
Control.
Rotating
the
RUN IN
Control
in
a
clockwise
direction
will
increase the
rate
of
the
wire feed.
When
the RUN IN
Control
is
set at
0,
wire
will
feed
at the
slowest
speed;
when set at
10,
the
wire
will
feed
at the fastest
speed.
The
scale which surrounds the
RUN
IN
Control
is
calibrated
in
increments of
one
ranging
from 0
to
10. Due
to
this
cali
bration,
it
should
be
noted
that
if
this scale
is
being
used
to
select
a
wire
feed
speed
setting, only
a
fraction
of
the
range
in
use
is
being
selected
and
not
an
actual wire
feed
speed
rate.
3-12.
PRE
FLOW CONTROL
(Figure3-1)
An
adjustable
shielding
gas
PRE-FLOW
Control
is
provided
for
controlling
the
period
of
time
shielding
gas
will
be
allowed
to flow before the
welding
wire
is
fed and subse
quent
arc initiation.
The PRE
FLOW
Control
governs
the
operation
of
a
Pre-Flow
Timer
within
the
weld
control.
Rotating
the
control
in
a
clockwise direction
will
increase
the
pre-flow
time. The scale
surrounding
the
PRE
FLOW
Control
is
calibrated
arbitrarily.
As
soon as
the
WELD START
Switch
(or
Remote
Start
Switch)
has
been
closed,
the
Pre-Flow
Timer
will
begin
to
time
out the
selected
period
of
pre-flow
time.
Once
the timer
has
timed
out,
the
gas
valve will remain
open,
the
welding
wire
will
begin
to
be
fed,
and the
contactor
will close
pro
viding
weld
power.
The
timer will
then
automatically
reset
and
be
ready
for
another
weld
cycle.
3-13.
POST FLOW
CONTROL
(Figure
3-1)
An
adjustable
0
to
1
second
shielding
gas
POST FLOW
Con
trol
is
provided
for
controlling
the
period
of
time
shielding
gas
will be allowed
to
flow after
the
arc
is
extinguished.
The
POST
FLOW
Control
governs
the
operation
of
a
Post-Flow
Timer within
the weld
control.
Rotating
the
control
in
a
clockwise
direction
will
increase the
post-flow
time.
The
scale
surrounding
the
POST
FLOW Con
trol
is
calibrated
arbitrarily.
As
soon
as
the
arc
has
been
extinguished,
the Post-Flow
Timer
will
begin
to
time
out the selected
period
of
post-flow
time.
Once
the timer
has timed
out,
the
gas
valve will close
and
thereby
terminate
shielding
gas
flow.
The
timer will then
automatically
reset
and
be
ready
for another weld
cycle.
3-14.
WELD
TIME
CONTROL
(Figure

A.
Spot
Weld
Mode
Of
Operation
An
adjustable
03
to
ZO
second
WELD TIME Control
is
pro
vided for
controlling
the
period
of time weld
power
will be
available for
spot
welding
in
this mode
of
operation.
The
WELD TIME Control
governs
the
operation
of
a
Spot
Timer
within the
welding
power
source.
Rotating
the
control
in
a
clockwise
direction
will
increase the
spot
time.
The
scale
surrounding
the
WELD
TIME
Control
is
calibrated
arbitrarily.
The
Spot
Weld Timer
will
begin
to
time
out
as soon
as an arc
is initiated. When the time
set
on
the
WELD
TIME
Control
has
elapsed,
weld
current
will
cease
and
the
Post-Flow
Timer
will be started.
B- Full
Automatic
Mode Of
Operation
The WELD
TIME
Control,
in
this mode of
operation,
adjusts
the
crater-fill
time from
0.3
to
2.0
seconds.
The crater-fill
time is the
time between
the
applied
signal
for
weld
cycle
stopping
and
the actual
welding
wire
stopping.
Rotating
this
control
clockwise
will
increase
the
crater-fill
time.
The
scale
surrounding
the
WELD TIME
Control
is
calibrated
arbi
trarily.
C.
Semi-Automatic
Mode
Of
Operation
The
WELD
TIME
Control,
in
this mode of
operation,
is in
operative.
3-15. OPERATIONAL

should
be
used
when
portable

FUNCTION
OF
CONTROLS
3-1.
WELD START
SWITCH
(Figure
2-2)
Rotating
the WELD START Switch
to
the
ON
position
will
apply
115
volts
ac
to the unit and
thereby
place
it in
an
operational condition,
ready
to
energize
the weld
head and
permit
shielding
gas
to
flow.
Rotating
the
WELD
START
Switch
to the
OFF
position
will
shut
the weld control down.
CAUTION__.!
Even
though
the
WELD START
Switin
the
OFF
position
and
the unit is
apparently shutdown,
115
volts will still
be
present
at
the
input
terminals of the
WELD START
Switch for
as
long
as
the 115 volts
cable
is
connected
to
its activated
source.
Depressing
(closing(
the WELD START Switch
push
button
(or
Remote Start
Switch) when
the
WELD START Switch
is
in
the
ON
position
will
commence
the

I is
depressed
when the

but
must
be
opened
and

2. WELD CURRENT
CONTROL
(Figure
2-2)
The WELD
CURRENT Control
provides
a means
of
deter
mining
the
rate at
which
welding
wire will
be
fed
into
the
weld
exclusive of
the
run-in
wire
feed
speed
as
governed
by
the
RUN IN
Control.
Rotating
the WELD CURRENT
Con
trol
in
a
clockwise
direction will increase
the
rate
of wire
feed. When
the
WELD CURRENT
Control
is
set
at
0,
wire
will
feed
at
the slowest
speed;
when
set at
10,
the
wire will
feed
at
the fastest
speed.
The scale which
surrounds the
WELD
CURRENT Control
is
calibrated
in
increments
of
one
ranging
from
0
to
10. Due
to
this
calibration,
it should
be
noted that if this
scale
is
being
used
to
select
a
wire
feed
speed
setting,
only
a
fraction of the
range
in
use
is
being
selected
and
not
an
actual
wire feed
speed
rate.

SWITCHES
(Figure
2-2)
Depressing
the
INCH
UP
Switch
energizes
the
weld head
motor to retract
the
welding
wire from the weld
at
the
run-in
speed
established
by
the
RUN IN
Control.
Depressing
the
INCH
DOWN
Switch
energizes
the weld head
motor
to
advance
the
welding
wire
to
the weld
at
the
run-in
speed
established
by
the
RUN
IN Control.
In
both the
inch-up
and
inch-down
modes,
the
contactor
in
the
welding
power
source
and
the
gas
control
circuitry
remain
deenergized.

PURGE SWITCH
(Figure

The
PURGE
Button is
a
normally
open
momentary
contact
switch. This
switch will
energize
the
gas
solenoid
GS1
and
purge
the
shielding
gas
line
of
the
gun.
The PURGE
Button
also allows the
shielding
gas
regulator
to be
adlusted
without
energizing
the
welding
circuit.

3-8.
CIRCUIT BREAKER
(Figure
2-2)
The
circuit breaker
provides
protection
to
the
weld control
and weld head
motor.
In
the
event
the
weld control
or
weld
head
motor
should
be
placed
in
an
overload
condition,
the
breaker
would
trip
and
suspend
all
output.
Should
this
breaker
trip,
the
reset
button
would have
to be
manually
depressed
in

METERS
(Figure
2-2)
This
weld
control is
equipped
with
a
dc
ammeter
and
a
dc
voltmeter.
These
meters
are
connected
to
the
welding
power
source
output.
The
voltmeter will
indicate the
dc
voltage
at
the
welding
power
source
secondary
terminals,
but
will
not
necessarily
indicate the actual
voltage
at
the
welding
arc.
If
the
welding
cables
are
excessively long,
or
have
poor,
loose
connections,
the
difference
between
actual
arc
voltage
and
the
voltage
at
the
welding
power
source
secondary
terminals
may
be considerable.
3-10.
BURNBACK
CONTROL
(Figure
3-1)
The BURNBACK
Control
regulates
the
amount
of
welding
wire that
protrudes
beyond
the end of
the
contact
tube
at
the
completion
of
a
weld
cycle.
In
other
words,
the BURN-
BACK Control
adlusts
the
welding
wire
burnback
time
from
0
to .5 second.
By
adjusting
this
control
properly,
the
weld
ing
wire
will
neither freeze
in
the weld
puddle
or
the
contact
tube.
Rotating
the BURNBACK Control
clockwise
increases
the
amount
of
welding
wire
burnback
towerd
the
contact tube.
The scale
surrounding
this
control is
calibrated
arbitrarily.
