When the mode switch is in the Lift TIG position, the
stick welding functions are disabled and the
machine is ready for Lift TIG welding. Lift TIG is a
method of starting a TIG weld by first pressing the
TIG torch electrode on the work piece in order to
create a low current short circuit. Then, the
electrode is lifted from the work piece to start the
TIG arc.
The last mode switch position, HF TIG, is only
available on the V160-T machines. When the mode
switch is in this position, the stick welding functions
are disabled and the machine is ready for HF TIG
welding. During the HF TIG mode, the TIG arc is
started by HF without pressing the electrode on the
work piece. The HF used for starting the TIG arc
will remain on for 6.5 seconds; if the arc is not
started in this time limit, the trigger sequence must
be restarted.
E. Trigger Mode Switch (V160-T machines only): This
switch changes between 2-step and 4-step trigger
sequences. For an explanation of these trigger
sequences refer to the trigger sequences explained
below.
F. Power LED: This indicator will flash on and off
when the machine is first turned on. After
approximately 2 seconds it will stop flashing and
remain on to signal that the machine is ready.
G. 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.
H. Remote LED (V160-T machines only): This
indicator will turn on when a remote control is
connected to the machine via the remote control
connector. Using a remote control will change the
function of the output current control, refer to the
output current control section below.
I. Output LED: This indicator turns on when the
output of the machine is on. Both the type of
machine and the position of the mode switch
determine when the output of the machine is turned
on.
V160-S: In both welding modes, selected by the
mode switch, the output of the machine is always
turned ON.
V160-T: In stick welding mode, the output of the
machine is automatically turned on. However, in
both of the TIG welding modes, the output of the
machine is turned ON and OFF by the TIG torch
connected to the trigger connector on the front of
the machine.
J. Arc Control (V160-S only): In stick welding mode,
this controls the amount of current used during any
intermittent short circuiting of the electrode during
welding. In TIG welding mode, this is not used.
K. Output Current Control: This controls the output, or
welding, current of the machine.
For V160-T machines, the function of this control
knob is changed if a remote control is connected. If
the Remote LED is ON, this indicates that a remote
control is connected and the function of the output
current control will be:
Stick Welding Mode: The remote control will
adjust the output current of the machine from 5 to
160A. The output current control knob on the
display panel is not used.
TIG Welding Modes: The maximum output current
of the machine is set by the output current control
knob. Then the remote control adjusts the output
current from the minimum output (5A) to the value
set by the output current control knob. For example,
if the output current control knob on the machine is
set to 100A then the remote control will adjust the
output current from a minimum of 5A to a maximum
of 100A.
L. Downslope Control (V160-T machines only): In the
TIG welding modes, this control knob will adjust the
downslope time from 0.5 to 20 seconds. (The
upslope time is always 0.5 seconds.) Refer to the
trigger sequence section below to understand how
downslope is activated. In Stick welding mode, this
is not used.
M. Postflow Control (V160-T machines only): In the
TIG welding modes, this control knob will adjust the
shielding gas postflow time from 0.5 to 30 seconds.
(The preflow time is always 0.5 seconds.) In Stick
welding mode, this is not used.
N. Meter (V160-T Pulse only): This meter displays the
preset welding current before welding and the actual
welding current during welding. Like the output
current control, the function of the meter is changed
if a remote control is connected. If the Remote LED
is ON, this indicates that a remote control is
connected and the meter will display the following
information before welding (during welding, the
meter always displays the actual welding current):
Stick Welding Mode: The meter displays the
preset welding current but this is adjusted from the
remote control as explained in the Output Current
Control section.
TIG Welding Modes: The meter displays the
maximum output current which is set by the output
current control knob. The preset welding current is
then adjusted by the remote control, but it is not
displayed on the meter.
O. Pulsing Mode Switch (V160-T Pulse only): In the
TIG welding modes, this switch turns the pulsing
function ON and controls the pulsing frequency
range (20Hz or 300Hz). In Stick welding mode, this
is not used.
P. Pulsing LED (V160-T Pulse only): This indicator
shows the pulsing frequency when pulsing is turned
ON. With this indication, the operator can adjust the
frequency to the desired value before welding.
(Note: At higher frequencies the LED flashes very
fast and seems to be continuously ON however it is
pulsing.) If pulsing is turned OFF or if the machine
