connector with the key lining up with the keyway and
rotate approximately ¼ turn clockwise. Do not over
tighten.
For DC(-) welding switch the cable connections at the
machine so that the electrode cable is connected to (-)
and the work clamp is connected to (+).
TIG Welding (GTAW)
This machine does not include a TIG torch necessary for
TIG welding, but one may be purchased separately.
Refer to the accessories section for more information.
Most TIG welding is done with DC(-) polarity; connect
the torch cable to the (-) terminal of the machine and the
work clamp to the (+) terminal. Insert the connector with
the key lining up with the keyway and rotate
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 /-TP 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
English
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
