ARFU (Auto-Restore FUse)
The dual input voltage machine is provided with the
ARFU device. It operates only when the input is
connected to the 115Vac mains and protects from input
overcurrent. When active, the "Power LED" blinks (see
"Controls and Operational Features" section).
Note: The ARFU device operates independently from
the machine's duty-cycle.
Output Connections
A quick disconnect system using
Twist-Mate cable plugs is used
for the welding cable connections.
Refer to the following sections for
more information on connecting
the machine for operation of stick
welding (MMA) or TIG welding
(GTAW).
Stick Welding (MMA)
First determine the proper electrode polarity for the
electrode to be used. Consult the electrode data for this
information. Then connect the output cables to the
output terminals of the machine for the selected polarity.
For example, if DC(+) welding will be used then connect
the electrode 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 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,
English
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).
