Lincoln Electric INVERTEC 170TX Series Operator's Manual page 12

Remote LED:
This indicator will turn on when a Remote command is
connected to the machine via the remote control
connector.
If a Remote command is connected to the Machine, the
Output Current knob operates in two different modes:
STICK and TIG:

STICK mode: with a Remote command
connected the output of the machine is ON. A
Remote Amptrol or Pedal are allowed (trigger is
ignored).
Connecting the Remote command excludes the
Output Current Knob of the Machine's user
interface. Through the Remote command is
available the full Output Current Range.

TIG mode: in Local and remote mode the
output of the machine is OFF. A Trigger is
necessary to enable the output.
For 170TX/TPX: The Output Current range
selectable from the Remote command depends by
the Machine's user interface Output Current Knob.
Eg.: if the Output Current is set to 100A with the
Machine's user interface Output Current Knob, the
Remote command will adjust the Output Current
from a minimum of 2A to a maximum of 100A.
For 220TPX: The Output Current range selectable
from the Remote command depends by the
Machine's user interface Output Current Knob. Eg.:
if the Output Current is set to 100A with the
Machine's user interface Output Current Knob, the
Remote command will adjust the Output Current
from the minimum current to a maximum of 100A.
The output current set by Output Current Knob is
shown for 3 second whenever the knob is moved.
After the 3 second the value shows is the current
select by the Remote command.
Remote Pedal: For a correct use, the "option 30"
must be enabled in the setup menu:

2-step sequence is automatically selected

Upslope / Downslope ramps and Restart are
disabled.

Spot, Bi-Level and 4-step functions aren't
selectable
(Normal operation is restored when the Remote
command is disconnected.)

Thermal LED:
This indicator will turn on when the machine is
overheated and the output has been disabled. This
normally occurs when the duty cycle of the machine has
been exceeded. Leave the machine on to allow the
internal components to cool. When the indicator turns
off, normal operation is again possible.
VRD LED (enabled on Australian Machines only):
This machine is provided by VRD (Voltage Reduction
Device) function: this reduces the voltage at the output
leads.
The VRD function is enabled by factory default only
on machines that meet the AS 1674.2 Australian
Standards. (C-Tick logo " " on/near the Rating Plate
applied on the machine).
The VRD LED is ON when the Output Voltage is below
12V with the Machine at idle (no welding time).
For others machines this function is disabled (the LED is
always OFF).
Mode Pushbutton:
This pushbutton changes the welding modes of the
machine:

Stick (SMAW)

Lift TIG (GTAW)

HF TIG (GTAW)

Spot TIG (GTAW)
The Spot TIG feature is selectable only if the "option
10" is previously enabled in the Setup Menu. See
"Setup menu" section for options enabling / disabling.
Each welding mode is is detailed in the Operating
instruction section.
Trigger Mode Pushbutton:
This pushbutton changes the trigger sequence in TIG
welding mode:

2-step / 4-step with restart This option is not
selectable by the Trigger Pushbutton and, if
enabled, operates with 2 or 4 step mode:
This indicator will turn on if the restart option is
enabled for the current TIG trigger mode. Restart
can be enabled separately for 2-step and 4-step
modes from the Setup Menu. More information
about restart is available in the Operating instruction
section.
