OPERATING
INSTRUCTIONS
DESCRIPTION
The
\!?l4
Solid State
Wire
Feeder has been designed to feed
a
range of hard, soft, and flux cored
wires
for the
(2s
MetalA-cc
Process and
is
suitable for connection to a
30
volt
50
hertz
single phase supply. The
well
proven
V.I.A.
2
Roll
Drive
As-
sembly
is
coupled to
a
Low Inertia Printed Circuit Motor/Gear-
box. This Printed Circuit
(P.M.)
Motor
is
controlled by
a
full
wave silicon controlled rectifier motor circuit, which ensures
constant motor speed and. torque over any pre-set speed range.
The motor control circuit and the
electric
function circuit
are
on printed circuit panels with
all
components,
test
pins,
etc.,
clearly
identified.
The
electrical
function control panel incorporates an infinitely
variable burn-back control, whilst the motor control panel has
a
torque feed back circuit, and
a
controlvoltage stabilisation
circuit.
The
Kire
Feeder
is
suitable for either spooled
or
coiled
wire.
Vire
alignment between input
wire
guides, feed rolls an6 gun
cable
is
pre-set and. maintained over the complete range
of
wire
sizes.
A
range
of
light weiuht qun and cable assemblies
are
available,
to
suit the
wire
types and
sizes
being used.
The
Wire
Feeder can be used. in both horizontal and vertical
positions, swivel mounted, or suspended overhead with stand-
ard easy fitting adaptors available for each installation
sit-
uation.
The welding current rating
of
the
Wire
Feeder
is
unlimited,
as
the welding current by-passes the
Wire
Feeder
and
is
determined
by
the power source, gun cable, and
size
(dia.
)
of the weldins
wire.
SETTING
UP
F7IRE
FEEDER
The
Wire
Feeder
is
shipped as
a
complete, stationary mounted
unit fitted with one
set
of feed rolls,
wire
guides and
spool

The
following accessories
are
available
as
standard

ALIGNMENT
As
referred to
earlier,
the
drive

input guides and gun cable
liners
are
prealigned when assembled in the factory and, therefore,
no
additional alignment
is
necessary when using any
of
the drive
rolls.
However ensure gun cable liner ferrule
is
adjusted
as
close
as
poss-
ible to drive
rolls
without touching.

Roll
Drive:
Release
the
pressure adjusting

and open
the
top
feed
roll yate assembly. Cut the end of the
wire
clean-
ly
so
it
is
free
of
all
burrs
and
kinks, and
is
perfectly straight.
Insert
the
wire
by
hand
through the input guide over the bottom
feed roll and enter
it
into
the
gun cable, ensuring
wire
fits
in
groove
of
feed roll. Pressure
is
then applied to the top feed
roll by lowerinq the top gate and adjusting the knurled
screw
until the
wire
is
gripped snugly by the feed roll.
NOTE:
Do
not exert undue pressure on the drive
rolls.
Examine
the
gun cable
liner
and
tip if
wire
is
not feeding correctly,
as
excessive drive roll pressure
will
cause
the
wire
to
deform
and "pick up"
with
resultant
wire
kinks which
will
cause uneven
wire
feed.

CIRCUIT
Iir14-C2
The
30
v.a.c.
supply
is
coupled to the control rectifier brid-ge
14-D9
and the SCR hybrid bridge
14-DIO.
Diodes
14-D1
and.
14-D2
form
a
negative supply point which
is
electrically common with
the negative control voltage.
Resistor
14-R9
and zener d.iode
14-D7
form
a
clippinq circuit
to
supply the unijunction oscillator
com-
prising 14-R5,?4-Hl,Tl and
14-Cl.
T1
is
a
pulse transformer
having two secondary windings which provide the appropriate gate
voltage
to the two SCR's
14-D1.1.
It
is
the unijunction oscillator
which facilitates phase shift control
of
the hybrid bridqe. Vhile
the motor relay
K1
remains de-energised,
14-C1
has no charging
path, hence the unijunction oscillator cannot operate, and the
SCR's are not triggered.
When the gun switch
is
closed, the gas valve
is
energised via diode
ll-D8.
Contactor relay
K2
is
energised
via
transistor
11-Hl,
and
the burn-back timing capacitor
ll-C2
is
charged.. The
motor
relay
K1
is
energised
via
diodes
11-Dl,
ll-D3 and resistor
ll-R3.
Diode
11-D4
with resistor-capacitor network
11-R6
and
ll-C1
ensures
that
K1
is
the
last
relay in
the
sequence to energise.
With
K1
energised, the output
of
the SCR hybrid bridge
is
connected
to the
wire
drive
motor.
Capacitor
14-C1
is
now provided with a
charging path,
via
transistor
14-H2
and
resistor
14-R6.
When the
charge in capacitor
14-C1
reaches
a
pre-determined
level,
the uni-
junction transistor
14-H1
conducts, dischargiqthe capacitor into
the primary winding of pulse transformer
TI.
This causes
a
voltage
pulse
to
appear
at
the gates of the
two
SCR's. The SCR which
is
forward biased (anode positive)
will
turn on
at
this point. The
motor
now begins
to
rotate, building up
to
the pre-set speed. The
amount of phase-shift
is
determined by the charging
time
of
14-C1,
which in turn
is
determined by the
level
of
conduction of transistor
14-H2.
The
base
voltage of
14-H2
is
controlled
by
the speed pot-
entiometer setting, while
its
emitter
voltage
is
in proportion
to
the back e.m.f. of the drive motor. Moving the potentiometer to
increase the motor speed makes the base
of
14-H2,
more negative.

On
release
of
the
gun switch,
the
gas
valve
is
de-energised, motor
relay
K1
opens, and
its
normally closed contacts place a
low
res-
istance
across
the
motor
armature, providing dynamic braking.
Contactor
relay
K2
is
held energised for
a
short
time,
determined
by the setting
of
potentiometer
ll-R5
which
forms
the discharge
path
for
capacitor
ll-C2.
This
is
called burn-back
time,
and
has the effect of preventing the welding
wire
from "freezing in
the weld puddle
at
the end
of
a
weld.

effect immediate repairs
to the equipment in the event of failure. The following faults,
however, can be checked.

Press
Inch Switch,
if

be
in

or
the switch

If
motor
does not turn visually check both printed circuit board's
and make sure that
all
componentry, wiring, and
electrical
connections
are
secure. Check motor relay

on printed
circuit board and ensure
it

POINTS
TO
WATCH
FOR
MAXIMUM
EFFICIENCY
Good
wire
feed
is
more
than dependent on good gun and cable main-
tenance, and the following points should be checked
at
all
times:-
(a)
Blow out gun
cables
and liner with dry compressed
air
at
regular
intervals
and, preferably,
after
each
spool
or
coil
of
wire.
(b)
Contact tips should
be
kept
clear
of spatter
and
hole size
should be checked regularly.
(c)
Regularly check gas lines and connections
for
tightness to
prevent porosity occurring in
weld.
(d) Keep gun cable free
from
sharp bends and loop
same
in
a
''C"
curve in preference to an
"S"
curve. If
Wire
Feeder can be
suspended overhead, this greatly improved consistency of
feed
rate.
(e)
For
C02
gas, use
gas
preheater
at
all
times
to
eliminate gas
flow irregularities caused
by
gas "freezing" of the regulator.
Full maintenance and operation instructions
for good gun cable
maintenance
are
set
out in Operation Manual
on
W.I.A.
Gun Cables.
