Remote Control Connection - Saf-Fro PRESTOTIG 315DC Bedienungsanleitung

Connect the electrode cable to the (+) terminal 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 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.
