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 shown
here. If DC(+) polarity is necessary switch the cable
connections at the machine.
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.
Finally, 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. The required
fittings are included in the package. Connect the TIG
torch trigger to the trigger connector (A) on the front of
the machine.
TIG Welding with a Water Cooled Torch
A cooling unit can be applied to the Machine:
COOLER-3 for 315DC
COOLER-4 for 415DC
If a COOLER unit listed above is connected to the
Machine, it will be automatically turned ON and OFF in
order to ensure the torch cooling. When Stick welding
mode is used the cooler will be OFF.
This machine does not include a cooled TIG torch, but
one may be purchased separately. Refer to the
accessories section for more information.
WARNING
The Machine is provided with an electrical connection for
the COOLER unit on its rear side. This socket is ONLY
for the connection of the COOLER unit listed above.
WARNING
Before connecting the cooler unit to the Machine and
operate, read and understand the Instruction Manual
supplied with the cooling unit.
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
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.
Rear Panel
A. Power Switch: It turns ON
/ OFF the input power to
the machine.
B. Input cable: Connect it to
the mains.
C. Fan: Do not obstruct or
filter the fan inlet. The
“F.A.N.” (Fan As Needed)
feature automatically turns
OFF/ON the fan. When
the Machine is turned ON the fan is turned ON only
for the startup time (few seconds). The fan will start
with welding operations and will continue to run
whenever the Machine is welding. If the Machine
doesn’t weld for more than 7½ minutes, it will go in
Green Mode.
Green Mode
The Green Mode is a feature that puts the machine in a
stand-by condition:
The output is disabled
The fan is turned OFF
Only the Power ON LED remains ON.
A moving red dash is shown in the “V” and “A”
displays
This reduces the amount of dirt that can be drawn inside
the Machine and the power consumption.
To restore the Machine restart to weld or push the TIG
torch trigger or push any button in the front panel or turn
the encoder knob.
NOTE: Green Mode long time condition: each 10min of
continuous Green Mode the fan runs for 1min.
NOTE: If a COOLER TIG torch cooling unit is connected
to the machine, it will be turned ON/OFF by the Green
Mode feature.
D. Gas Inlet: Connector for the TIG shielding gas. Use
the supplied connector to connect the machine to the
gas source line. The gas source must have a
pressure regulator and flow gage installed.
E. Power supply socket for COOLER: 400Vac socket.
Connect here the COOLER cooling unit.
