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. Shown
here is the connection method for DC(+) welding.
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
Power Switch: It turns ON / OFF the input power to
the machine.
Input cable: Connect it to the
mains.
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.
