Output Connections - Lincoln Electric INVERTEC V270 Bedienungsanleitung

Output Connections

A quick disconnect system
using Twist-Mate cable
plugs is used for the
welding cable connections.
Refer to the following
sections for more
information on connecting
the machine for operation of
stick welding (MMA) or TIG
welding (GTAW).
Stick Welding (MMA)
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. For example, if DC(+) welding will be used then
connect the electrode 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 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; 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 V205-S / V270-S / V405-S machine, connect the gas
hose from the TIG torch to a gas regulator on the
cylinder of gas to be used.
For V205-T / V270-T /
V405-T 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.
Controls and Operational Features
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.
If a Coolarc 20 is connected to a V205-T / V270-T, it
will be turned ON and OFF with the operation of the
fan. When Stick welding mode is used the Coolarc
20 will be OFF.
If a Coolarc 30 is connected to a V405-T, it will be
turned ON and OFF with the operation of the fan.
When Stick welding mode is used the Coolarc 30
will be OFF.
C. Gas Inlet (V205-T / V270-T / V405-T only):
Connector for the TIG shielding gas. Use the
supplied gas line and connector to connect the
machine to the gas source. The gas source must
have a pressure regulator and flow gage installed.
D. Mode Switch: This switch changes the welding
modes of the machine. The V205-S / V270-S /
V405-S have two welding modes: Stick (SMAW)
and Lift TIG (GTAW). The V205-T / V270-T / V405-
T machines have three welding modes: Stick
(SMAW), Lift TIG (GTAW) and HF TIG (GTAW).
