approximately ¼ turn clockwise. Do not over tighten.
For V160-S machines, connect the gas hose from the
TIG torch to a gas regulator on the cylinder of gas to be
used.
For V160-T machines,
connect the gas hose
from the TIG torch to
the gas connector (B)
on the front of the
machine. If necessary,
an extra gas connector
for the fitting on the
front of the machine is
included in the package. Next, connect the fitting on the
back of the machine to a gas regulator on the cylinder of
gas to be used. An input gas line and the required
fittings are also included in the package. Connect the
TIG torch trigger to the trigger connector (A) on the front
of the machine.
Remote Control Connection
For V160-T machines only, refer to the accessories
section for a list of remote controls. If a remote control is
used, it will be connected to the remote connector (C) on
the front of the machine. The machine will automatically
detect the remote control, turn on the REMOTE LED,
and switch to remote control mode. More information on
this mode of operation will be given in the next section.

Controls and Operational Features

A. Power Switch:
Controls the input
power to the machine.
Make sure the
machine is properly
connected to the input
supply before turning
the machine on.
B. Fan: The cooling fan
will turn ON when the
machine is turned ON
and it will continue to
run whenever the
output of the machine
is ON. If the output of
the machine is OFF
for more than five minutes, the fan will turn OFF.
This reduces the amount of dirt that is deposited
inside the machine and reduces power
consumption.
Refer to the Output LED section below for more
information about conditions when the output of the
machine is ON. The V160-S always has the output
turned ON so the fan will not turn OFF. Additionally,
when the V160-T machines are in Stick mode, the
fan will not turn OFF because the output remains
ON.
C. Gas Inlet (V160-T machines only): Connector for
the TIG shielding gas. Use the supplied gas line
and connector to connect the machine to the gas
source. The gas source must have a pressure
regulator and flow gage installed.
D. Mode Switch: This switch changes the welding
modes of the machine. The V160-S has two
welding modes: Stick (SMAW) and Lift TIG (GTAW).
The V160-T machines have three welding modes:
Stick (SMAW), Lift TIG (GTAW) and HF TIG
(GTAW).
When the mode switch is in the Stick position, the
following welding features are enabled:
•
Hot Start: This is a temporary increase in the
output current during the start of the stick
welding process. This helps ignite the arc
quickly and reliably.
•
Arc Force: This is a temporary increase in the
output current during normal stick welding.
This temporary increase in output current is
used to clear intermittent connections between
the electrode and the weld puddle that occur
during normal stick welding. The amount of arc
force can be adjusted on the V160-S, refer to
Arc Control, described below.
•
Anti-Sticking: This is a function which
decreases the output current of the machine to
a low level when the operator makes an error
and sticks the electrode to the work piece. This
decrease in current allows the operator to
remove the electrode from the electrode holder
without creating large sparks which can
damage the electrode holder.
