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 "V -S" machine, connect the gas hose from the
###
TIG torch to a gas regulator on the cylinder of gas to be
used.
For "V -T / -TP" machine,
###
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
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.

WARNING
Arc Striking Machine Usage Information
(ASG machines only)
The EN 60974-3 Standard specifies that the "ASG"
equipment is intended to be used with mechanically
guided torch.
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.
