LN-7 Connection Instructions
An LN-7 can only be used with the “Factory” &
“Advance Process” versions of the 350-Pro.
• Turn the Invertec power switch "off".
• Connect the K480 control cable from the LN-7 to the
115VAC 14-pin wire feeder MS-style connector on the
rear of the Invertec.
• Connect the electrode cable to the output terminal of
the polarity required by electrode. Connect the work
lead to the other terminal.
• Set the meter polarity switch on the front of the Invertec
to coincide with wire feeder polarity used. The wire
feeder will now display the welding voltage.
• If K480 is not available, see connection diagram
S19404 for modification of K291 or K404 LN-7 input
cable with K867 Universal Adapter Plug.
• If a remote control such as K857 is to be used with the
LN-7, the remote can be connected directly to the 6-pin
MS-style connector on the front of the Invertec or use a
K864 adapter to connect the LN-7 and the remote to
the 115VAC 14-pin MS-style connector on the rear of
the Invertec. (See connection diagram S19901)
LN-10 Connection Instructions
An LN-10 can only be used with the “Factory” &
“Advance Process” versions of the 350-Pro.
• Turn the Invertec power switch "off"
• Connect the K1505 control cable from the LN-10 to the
Invertec 24/42VAC 14-pin MS-style connector on the
rear of the Invertec.
• Connect the electrode cable to the output terminal of
polarity required by the electrode. Connect the work
lead to the other terminal.
• Set the meter polarity switch on the front of the Invertec
to coincide with wire feeder polarity used.
• See the LN-10 manual for details on accessing Control
DIP Switch
LN-742 Connection Instructions
An LN-742 can only be used with the “Factory” &
“Advance Process” versions of the 350-Pro.
• Turn the Invertec power switch "off"
• Either a K591 or a K593 Input cable assembly is
required to connect the LN-742 to the Invertec.
• Connect the control cable from the LN-742 to the
24/42 VAC 14-pin wire feeder MS-style connector
on the rear of the Invertec.
• Connect the electrode cable to the output terminal
of the polarity required by electrode. Connect the
work lead to the other terminal.
• Set the meter polarity switch on the front of the
Invertec to coincide with wire feeder polarity used.
The wire feeder will now display the welding volt-
age.
• If a remote control such as K857 is to be used with the
LN-742, the remote can be connected directly to the 6-
pin MS-style connector on the front of the Invertec or use
a K864 adapter to connect the LN-742 and the remote to
the 24/42VAC 14-pin wire feeder MS-style connector on
the rear of the Invertec.
Cobramatic Connection Instructions
A Cobramatic can only be used with the “Factory” &
“Advance Process” versions of the 350-Pro.
• Turn the Invertec power switch "off"
• Connect the control cable from the Cobramatic to
the 24/42 VAC 14-pin wire feeder MS-style con-
nector on the rear of the Invertec.
• Connect the electrode cable to the output terminal
of the polarity required by electrode. Connect the
work lead to the other terminal.
• Set the meter polarity switch on the front of the
Invertec to coincide with wire feeder polarity used.
• If a remote control such as K857 is to be used with
the Cobramatic, the remote can be connected
directly to the 6-pin MS-style connector on the front
of the Invertec or use a K864 adapter to connect
the cobramatic and the remote to the 24/42VAC
14-pin wire feeder MS-style connector on the rear
of the Invertec.
TIG Module K930-2
The TIG Module connects to the K1728-1 and K1728-4
V350-Pro versions with a K936-1 (9-14 pin) control
cable. Connect the K936-1 to the 115VAC Wire
Feeder Ms-style connector on the rear of the V350-
Pro.
The TIG Module can also be used with the K1728-2
V350 Construction version. A K936-4 control cable is
required to supply 115VAC to the TIG Module from
an external 115VAC supply.
General Instructions for Connection of Wire
Feeders to V350-Pro
Wire feeders other than those listed above may be
used provided that the auxiliary power supply rating of
the V350-Pro is not exceeded. K867 universal
adapter plug is required. See connection diagram
S24985 on page F-4.
