OPERATION
B-6
Bi-Level Current –
(If Enabled from
the Setup Menu) Depressing an arc
start switch and releasing will initiate
the arc to current level A1.
Depressing and releasing the arc
Start switch again will toggle to cur-
rent level A2. Each depressing and
releasing of the switch will toggle
between A1 and A2. Depressing and
holding the switch in will initiate the
down slope to the finish current level
and finally releasing the trigger will
extinguish the arc.
Spot Timer -
(If Enabled from the
Setup Menu) Selecting this trigger
mode will enable a spot timer para-
meter setting to be displayed as a
welding parameter. Once the arc is
establish the machine will weld for the
time period set by the spot timer para-
meter setting. The machine will follow
the functionality of two-step in that
start current, up-slope, down-slope
and finish current can all be adjusted.
STICK TRIGGER MODES
Local -
In this mode the machine
ignores any remote that is plugged.
The machine will weld at the preset
value set at the panel of the machine.
Remote -
Allows the amperage to be
set with a remote potentiometer.
C. TIG PULSE MODES
Pulse On -
Turns on pulse welding in
TIG mode. Changes the sequence
diagram to Pulse TIG and allows the
adjustment of the following added
parameters:
• Pulse Frequency
• % Peak Time
• Background Current
Pulse Off -
Turns off pulse welding in
TIG.
D, E, & F. Memory Operation –
Pressing and releas-
ing the memory location
(D)
button will scroll through
memory locations 1 through 10. When a memory is
recalled or saved the memory location display will
change to reversed text indicating that the current
memory parameters are active.
Normal Display Reversed Display
(Unselected)
(Selected)
Saving to Memory
• Press and hold Memory Save Button
(E)
until the
memory location display indicator
(D)
changes to a
reverse text indicating that the current parameters
are the ones in the actively selected memory.
Recalling from Memory
• Press and hold the memory recall button
(F)
until
the memory location display indicator
(D)
changes
to reversed text indicating that the stored parame-
ters are actively recalled.
When memory parameters are actively selected,
the display indicator will remain reversed until a
welding parameter is changed with the encoder
knob or until the memory location button is pressed
to scroll to a different memory location
Local/Remote Operation –
The Invertec® V311-T
AC/DC, when in TIG mode, will automatically sense
when the machine has a remote device plugged into
the 6 pin MS-type connector-like a remote pendant or
a foot amptrol. If a remote device is plugged in, the
machine will automatically function in remote mode. If
no device is plugged in, the machine will function in
local mode.
In remote mode, the operation of the machine is
slightly different depending on whether the remote
device is a foot amptrol or a remote pendant. To let
the machine know what type of device is plugged in,
the operator must select the appropriate device from
the trigger mode button. (See Trigger mode descrip-
tions above for details on the difference. In stick
mode the second button on the control panel selects
local or remote operation manually. This is required
so that the user does not need to detach a foot amp-
trol to use the machine in STICK mode.
