Remote Control Connection - Lincoln Electric INVERTEC V205-T Operator's Manual

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. Connect the
water hoses to the water connectors on the front of the
Coolarc if the machine is completed with a Coolarc
water-cooler.

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.
Assembly of the Coolarc 20 or Coolarc 30
A Coolarc water-cooler can be mounted below the V205-
T AC/DC or V305-T AC/DC and will convert the machine
to a water-cooled system. Use a Coolarc 20 with the
V205-T AC/DC and a Coolarc 30 with the V305-T
AC/DC.
Disconnect the machine from the power line. On the
V205-T AC/DC, remove the small excess door on the
bottom of the machine and put the electrical plug of the
Coolarc 20 in the connector. On the V305-T AC/DC,
remove the left side panel of the machine and put the
electrical plug of the Coolarc 30 in the connector located
above the hole on the top shelf. Place the machine on
top of the Coolarc and ensure the correct position in the
prepared holes. Attach the machine to the Coolarc with
the supplied screws.
Controls and Operational Features
L1 - Voltage Warning Light: This green indicator is ON
when the machine is switched ON with the main switch.
L2 - Safety Warning Light: This yellow indicator is ON
when a thermal overheating or incorrect supply voltage
error occurs. When this indicator is ON, an alarm code
will flash on the display (D1). In this condition the
machine does not supply power, the output is OFF. If a
thermal overheating error occurs, leave the power
source ON and allow it to cool. Or, in the case of a
supply voltage error, press any button to resume
operation.
V205-T AC/DC only: L3, L4 - VRD (Voltage Reduction
Device) Status Lights: Voltage reduction device can be
enabled from the set-up menu and an output voltage
limit can be set that reduces the output open circuit
voltage when not welding to that limit. If enabled when
the machine is sitting idle the Green VRD on light will
illuminate to indicate the voltage is reduced below the
set limit. If the VRD device is not enabled (factory
default) from the set up menu or while welding the red
VRD off light will illuminate. Enabling VRD will sacrifice
stick welding performance when using E6010 type
electrodes.
D1 - Display: Shows the welding current or the value of
the welding parameter chosen with pushbotton S4. It is
also used to display alarm or error messages and to
adjust the set-up parameters.
F1 - Current and Function Control: Pre-setting of the
welding current, welding parameters and set-up values.
This allows you to continuously adjust the current both in
TIG and in MMA welding. This current stays unchanged
when the supply and welding conditions vary within the
allowed ranges. In MMA welding, the presence of HOT-
START and ARC-FORCE means that the average
output current may be higher than that set at some
stages of the welding process. Allows you to change the
value, shown on the display (D1), of the parameter
selected with pushbotton S4. Allows you to specify the
required set-up line and to vary the value.
S1 - Mode Selection: Process selector. The LED
beside the symbol will light up to confirm the selection:
Stick Welding (V205-T AC/DC only: Soft Stick, Crisp
Stick), DC TIG Welding, or AC TIG Welding.
S2 - Trigger Selection: Trigger mode selector. The
LED beside the symbol will light up to confirm the
selection: 4 Step operation or 2 Step operation. Refer to
section below on TIG Trigger Sequences for a complete
explanation of these operations.
S3 - Local/Remote Switch: Current control selector.
The LED beside the symbol will light up to confirm the
selection: Local Current Control (F1) or Remote Current
Control.
S4 - Set-up/Parameter Switch: Allows entry into the
set-up menu and parameter selection.
Parameter Selection
By pushing the pushbutton S4 (after the start up
procedure) you can select the following TIG parameters:
• Start Current (A)
•
Upslope Time (sec)
•
Weld Current (A)
• Downslope Time (sec)
•
Finish Current (A)
•
Postflow Time (sec)
Press and hold the pushputton S4 for 2 seconds to
select the following AC parameters:
•
AC/DC TIG Frequency (Hz)
• Wave Balance
