Meter Functions For Invision 456P
1 Power Switch

The fan
motor
is thermostatically
control/ed and only
runs
when coo/mg is
needed.

Voltage/Amperage Control Switch
For front
panel
control,
place
switch in Panel
position
and
use
the V/A Adjust
control.
For remote control,
make connections to Re
mote 14 receptacle, and place
switch in Re
mote position.
In most modes,
remote
control
is
a
percent
of the V/A
Adjust
control setting.
Value selected
on
V/A Adjust
is maximum
available
on
remote. In the MIG
mode, remote
control provides full
range
of unit output
re
gardless
of
V/A Adjust
control
setting.
6 Mode Switch
The Mode switch
setting
determines both the
process arid output On/Off control (see Sec
tion 3-6). Source of control (panel
or
remote)
for the
amount
of
output
is selected
on
the
V/A
Control switch.
For Air Carbon Arc (CAC-A) cutting and
goug
ing, place switch in the Stick position. For best
results, place Inductance/Dig
control in the
maximum position.
7 Inductance/Dig Control
Control
adjusts Dig when the Stick
or
CC
mode is selected
on
the Mode switch. When
set towards minimum, short-circuit
amperage
at low
arc
voltage
is the
same as
normal weld
ing
amperage.
When set towards maximum,
short-circuit
am
perage is increased at low
arc
voltage to
assist
with
arc
starts
as
well
as
reduce sticking while
welding (see volt-ampere
curves
in Section
2-3).
Select
setting
best suited for
application.
Control adjusts inductance when MIG
position
is selected
on
the Mode switch. Inductance
determines the wetness of the weld
puddle.
When set towards maximum, wetness
(puddle fluidity) increases.
When Pulsed MIG,
or one
of the TIG modes is
selected, this control is not functional.
N OT E
The
meters
display the actual weld
output
values for
approximately three seconds
after the
arc
is broken.
