INVERTEC® V450-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.
9. SERIAL PORT FOR SOFTWARE UPDATES
10. 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 heading. (See
Item 8 or 8A for specified Mode Operations) (See Figure
B.1 or B.2)
LOWER CASE PANEL
The output studs, Meter Polarity switch and remote connector
are located on the lower case front.
11. Both Output terminals are "STUD" connectors.
12. 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 position of
the electrode polarity indicated by the decal. The switch
does not change the welding polarity.
13. 6-pin MS-style connector for remote control.
14. 14-PIN MS-style connector for wire and remote control.
15. AUXILIARY POWER
• 115VAC, 42VAC and 24VAC power is available from the
14-pin MS-style connector.
• 42 VAC supply is rated at 10 amps.
• 24 VAC supply is rated at 10 amps.
• 115VAC outlet rated at 15* amps.
* Earlier models used a 10 amp circuit breaker.
REMOTE CONTROL SELECTION
The Invertec® V450-Pro has auto sensing of remote output
controls. If after connecting or removing a remote, the
Invertec® V450-Pro did not configure the way you would like
the local or remote control settings can be changed by push-
ing the OUTPUT CONTROL or WELD TERMINAL button. (A
user cannot select between the 6 and 14 pin MS-style con-
nectors.)
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 con-
nector 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 con-
trol devices attached, the WELD TERMINAL control
will default to ON.
CC-Stick Modes
• The remote will default to only the 6-pin MS-style
connector 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® V450-Pro’s 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 connected 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 2,000 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 machine’s 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 cur-
rent that has been set by the Invertec® V450-Pro’s
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 refer-
enced to earth ground, any auxiliary power from the
Invertec® V450-Pro or the welding output) The sup-
ply should be capable of supplying at least 20mA.
• 0 volts supplied to 76 will set the Invertec® V450-Pro
to minimum output for the mode that has been
selected while 10 volts supplied to 76 will set the
Invertec® V450-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® V450-Pro’s front panel Output
Control.)
