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 current 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 theSetup
Menu)
Selecting this trigger mode will enable a spot
timer parameter 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 parameter
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.
Push button B: Trigger Modes

(Unselected)
Saving to Memory
•
Press and hold Memory Save Button (E) for 3
seconds to save to memory. The Memory location
display indicator (D) will change 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) for 3
seconds until the memory location display indicator
changes to reversed text indicating the stored
parameters 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 V270-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 pedant 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 descriptions 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 amptrol to use the machine in
STICK mode.
