INVERTEC® V350-PRO (CE)

LN-15 Connection Instructions

• 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

• 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

"CE" version of the V350. The 6-Pin (K444-1) and 14-pin
(K444-2) remotes can be connected directly to the 6-pin
& 14-pin MS-style connector. The 42 Volt Remote
Voltage and Output Control (K624-1) Kit can be connect-
ed to the V350’s 14-pin MS-style connector using
Remote Control Cable assembly K627- [ ]. LN-25s with a
K431-1 remote kit can be connected to the V350’s 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 connect it to
the V350’s 14-pin MS-style connector.

LN-742 Connection Instructions

• 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

• 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.

CONNECTION OF WIRE FEEDERS TO V350-PRO (CE)

Wire feeders other than these listed may be used pro-
vided that the auxiliary power supply capacity of the
Invertec

is not exceeded. K867 Universal Adapter

Plug may be required. See connection diagram
S24985 on page F-4.

REMOTE CONTROL OF INVERTEC

Remote Control K857, Hand Amptrol K963 and Foot
Amptrol K870.
