LN-10 Connection Instructions

• Turn the EX350i power switch "off"

• Connect the K1505 control cable from the LN-10 to the

EX350i 24/42VAC 14-pin amphenol connector on the

rear of the EX350i.

• 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 EX350i to

coincide with wire feeder polarity used.

• See the LN-10 manual for details on accessing Control

DIP Switch

LN-742 Connection Instructions

• Turn the EX350i power switch "off"

• Either a K591 or a K593 Input cable assembly is

required to connect the LN-742 to the EX350i.

• Connect the control cable from the LN-742 to the

24/42 VAC 14-pin wire feeder amphenol on the rear

of the EX350i.

• 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

EX350i to coincide with wire feeder polarity used.

The wire feeder will now display the welding volt-

age.

• If a remote control is to be used with the LN-742,

the remote can be connected directly to the 3 pin

amphenol on the front of the EX350i or use a K864

adapter to connect the LN-742 and a K857 remote

to the 24/42VAC 14-pin wire feeder amphenol con-

nector on the rear of the EX350i.

Cobramatic Connection Instructions

• Turn the EX350i power switch "off"

• Connect the control cable from the Cobramatic to

the 24/42 VAC 14-pin wire feeder amphenol on the

rear of the EX350i.

• 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

EX350i to coincide with wire feeder polarity used.

• If a remote control is to be used with the

Cobramatic, the remote can be connected directly

to the 3 pin amphenol on the front of the EX350i or

use a K864 adapter to connect the cobramatic and

a K857 remote to the 24/42VAC 14-pin wire feeder

amphenol connector on the rear of the EX350i.

INSTALLATION

TIG Module K930-2

The TIG Module connects to the EX350i with a K936-

1 (9-14 pin) control cable. Connect the K936-1 to the

115VAC Wire Feeder Amphenol on the rear of the

EX350i.

General Instructions for Connection of Wire

Feeders to EX350i

Wire feeders other than LN-7 and LN-25 may be used

provided that the auxiliary power supply capacity of

the EX350i is not exceeded. K867 universal adapter

plug is required. See connection diagram S24985 on

page F-4.
