WIRE FEED MODULE™
CONNECTION OF LINCOLN ELECTRIC WIRE FEEDERS
Shut off welder before making any electrical connections.
------------------------------------------------------------------
CONNECTION OF LN-25 TO THE WIRE FEED MODULE
The LN-25 with internal “COLD TIP” contactor requires the K2614-6
Control Cable for voltage control at the feeder.
The LN-25 with internal “Cold Tip” Contactor can be operated without
a control cable (Volt sensing mode) if voltage control at the wire feed-
er is not desired.
See the appropriated connection diagrams in the Diagrams section.
a) Shut off the welder.
b) Connect the electrode cable from the LN-25 to the positive stud of
the welder. Connect the work cable to the CV negative stud of the
welder. (NOTE: reverse the connections for negative electrode
polarity.)
c) For LN-25’s with internal contactor, connect the K2614-6 remote
voltage control cable from the LN-25 to the14-pin receptacle on
the control panel.
d) Attach the single lead from the front of the LN-25 to the work
using the spring clip on the end of the lead. This is a control lead
to supply current to the wire feeder motor; it does not carry weld-
ing current. Set the polarity switch on the LN-25 to the proper
polarity.
e) Set the “Current Range Selector” switch to the “190-120” position
for most common processes, this may be changed if a different
arc characteristic is preferred.
f) Set the “LOCAL/REMOTE” Control switch to the “REMOTE” posi-
tion. If operating an LN-25 with internal “Cold Tip” Contactor but
without the K2614-6 Remote Voltage Control Cable set the
“Local/Remote” Control Switch to the “Local” position.
g) Set the “IDLER” switch to the “HIGH” position. The “AUTO” posi-
tion may be used with some high current processes.
CONNECTION OF THE LN-7, LN-7 GMA TO THE WIRE FEED
MODULE
Requires K584-(L) input cable, K864 adapter and optionally the
K857 for remote control. See the connection diagram in the
Diagrams section.
a) Shut the welder off.
b) Connect the electrode cable from the LN-7 to the positive stud
of the welder. Connect the work cable to the CV negative stud
of the welder. (
NOTE
: Reverse the connections for negative
electrode polarity.)
c) Connect the LN-7 per the instructions on the appropriate con-
nection diagram.
d) Set the “Current Range” switch to the “190-120” position for
most common processes, this may be changed if a different
arc characteristic is desired.
e) Set the “LOCAL/REMOTE” control toggle switch to “REMOTE”.
f) Set the “IDLER” switch to the “AUTO” position. The “HIGH”
position may be required when used with some low current
processes.
CONNECTION OF THE LN-23P TO THE WIRE FEED MODULE
Requires the K350-1 adapter kit. Adapter kit provides an isolated
trigger voltage and allows connection of two wire feeders. See
connection diagram in the Diagrams section.
a) Shut the welder off.
b) Connect the electrode cable from the LN-23P to the CV nega-
tive output stud of the engine welder. Connect the work cable
to the positive output stud.
c) Mount K350-1 adapter per instructions included with adapter.
d) Connect LN-23P per instructions on appropriate connection
diagram.
e) Connect control lead marked “21” to work connection. Refer
to connection diagram in Diagrams section for routing instruc-
tions and wire size.
f) Set the “Current Range Selector” switch to the “190-120”
(middle position) for most common processes, this may be
changed if a different arc characteristic is preferred.
g) Set the “LOCAL/REMOTE” control toggle switch to “REMOTE”.
h) Set the idler switch to the “AUTO” position. The “HIGH” posi-
tion may be required when welding with low current process-
es.
