LN-10 Connection Instructions
An LN-10 can only be used with the “Factory” &

Advanced Process” versions of the 350-Pro.

• Turn the Invertec power switch "off"
• Connect the K1505 control cable from the LN-10 to the

14-pin MS-style connector.

• 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-15 Connection Instructions
(Factory, Construction & Advanced Process versions
can be connected.
• Turn the Invertec power switch "off".
• Connect the electrode cable to the output terminal of

polarity required by electrode. (See Figures below)

• Set the meter polarity switch on the front of the Invertec

to coincide with wire feeder polarity used.

LN-25 Connection Instructions
(Factory, Construction & Advanced Process versions
can be connected.
• Turn the Invertec power switch "off".
• Connect the electrode cable to the output terminal of

polarity required by electrode. Connect the work lead to
the other terminal.

• LN-25 with Remote Control options can be used with the

Factory and Advanced Process version of the V350. The
6-Pin (K444-1) and 14-pin (K444-2) remotes can be con-
nected directly to the 6-pin & 14-pin MS-style connectors.
The 42 Volt Remote Voltage and Output Control (K624-1)
Kit can be connected to the V350ʼs 14-pin MS-style con-
nector using Remote Control Cable assembly K627- [ ].
LN-25s with a K431-1 remote kit can be connected to the
V350ʼs 14-pin MS-style connector using a K432 cable and
K876 adapter. (See connection diagram S19899). Or the
K432 cable could be modified with a K867 Universal
Adapter Plug (See connection diagram S19405) to con-
nect it to the V350ʼs 14-pin MS-style connector.

LN-742 Connection Instructions

An LN-742 can only be used with the “Factory” &

Advanced 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

14-pin MS-style connector.

• 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 14-pin MS-style connector.

Cobramatic Connection Instructions

A Cobramatic can only be used with the “Factory” &

Advanced Process” versions of the 350-Pro.

• Turn the Invertec power switch "off"
• Connect the control cable from the Cobramatic to

the 14-pin MS-style connector.

• 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 14-pin MS-
style connector.

TIG Module K930-2
The TIG Module connects to the Factory and Advanced
Process V350-Pro versions with a K936-1 (9-14 pin)
control cable. Connect the K936-1 to the MS-style
connector.

The TIG Module can also be used with the V350-Pro
Construction version. A K936-4 control cable is
required to supply 115VAC to the TIG Module from
an external 115VAC supply.
