INVERTEC® V350-PRO
LN-10/DH-10 Wire Feeder Compatibility Note:
The LN-10 and DH-10 feeders can be used to pulse weld
and in the power mode with the panel. The displays on the
LN-10 & DH-10 do not show the wire feed speed or power.
8. HOT START and ARC CONTROL features have different
functions depending on the welding Mode that is active.
Each feature is described under the welding mode head-
ing. (See Item 7 or 7.A for specified Mode Operations)
(See Figure 1 or 2)
LOWER CASE PANEL (See Figure 1)
The output studs, line switch and remote connector are
located on the lower case front.
9. Both terminals are "Twist-Mate" connectors.
The Negative terminal is configured to accept the pass
through gas system except Code 11445 , which has no
gas pass-through and is equipped with “Tweco” connec-
tors).
10. The METER POLARITY switch is located above the out-
put connectors. The switch provides a work connection
for wire feeder voltmeters. Place the switch in the posi-
tion of the electrode polarity indicated by the decal. The
switch does not change the welding polarity.
11. 6-pin MS-style connector for remote control.
12. 14-pin MS-style connector for wire feeder connection
and remote control.
REMOTE CONTROL of the OUTPUT CONTROL and
WELD TERMINALS
The Invertec V350-Pro has auto sensing of remote output
controls. If after connecting or removing a remote, the
Invertec V350-Pro did not configure the way you would like
the local or remote control settings can be changed by
pushing the OUTPUT CONTROL or WELD TERMINAL but-
ton. (A user cannot select between the 6 and 14 pin MS-
style connectors.)
CV modes
• The remote will default to the 14-pin MS-style connector if
a remote is connected. If no remote is connected to the
14-pin MS-style connector then the remote will default to
the 6-pin MS-style connector if a remote is connected to it.
• In all of the CV modes, the WELD TERMINAL control will
default to REMOTE.
TIG mode
• The remote will default to the 6-pin MS-style if a remote
control is connected to the 6-pin MS-style and to the 14-
pin MS-style connector. If a remote is not connected to the
6-pin MS-style connector then the remote will default to
the 14-pin MS-style connector if a remote is connected.
• If a remote control is connected to any of the MS-style
connectors the WELD TERMINAL control will default to
REMOTE. If there are not any remote control devices
attached the WELD TERMINAL control will default to ON.
CC -Stick modes
• The remote will default to only the 6-pin MS-style connec-
tor if a remote is connected to it.
• The WELD TERMINAL control will default to ON with or
without a remote connected.
Types of Remote OUTPUT CONTROL
• The Invertec V350-Proʼs Output Control can be controlled
by either a potentiometer connected between 77 & 75 with
the wiper connected to 76 or a 0V to 10V DC supply con-
nected between 76 & 75. (76 needs to be positive)
• 14-Pin Ms-style connector lead 75 is pin G, lead 76 is pin
F and lead 77 is pin E.
• 6-Pin Ms-style connector lead 75 is pin C, lead 76 is pin B
and lead 77 is pin A.
Potentiometer Control
• The total resistance should be between 2000 ohms (2K)
and 10,000 ohms (10K)
• The machine output will be at minimum when lead 76
(wiper) is at the end of the potentiometer that is connected
to 75. The machineʼs output will increase as the wiper of
the potentiometer is moved to the end that is connected to
77. (Note: In TIG mode, moving the lead 76 (wiper) to lead
77 would produce the current that has been set by the
Invertec V350-Proʼs front panel Output Control.)
• Remotes of this type offered by Lincoln Electric are the
K857, K812 and K870.
Voltage Control
• The supply should be an isolated supply. (Not referenced
to earth ground, any auxiliary power from the Invertec
V350-Pro or the welding output) The supply should be
capable of supplying at least 20mA.
• 0 volts supplied to 76 will set the Invertec V350-Pro to
minimum output for the mode that has been selected
while 10 volts supplied to 76 will set the Invertec V350-Pro
to the maximum output for the mode. (Note: In TIG mode,
10 volts supplied to lead 76 would produce the current
that has been set by the Invertec V350-Proʼs front panel
Output Control.)
Types of Remote WELD TERMINAL Control
• The Invertec V350-Proʼs Weld Terminals can be con-
trolled from each of the MS-style connectors. The circuit
has a nominal OCV of 15VDC and requires a dry contact
closure (less than 100 ohms) to activate the output of the
Invertec V350-Pro.
• 14-Pin MS-style connector, the Weld Terminals are con-
trolled from pin C (lead 2) and pin D (lead 4). Pin C is posi-
tive.
• 6-Pin MS-style connector, the Weld Terminals are con-
trolled from pin D (lead 2) and pin E (lead 4). In the 6-pin
MS-style connector pin D is positive.
