INSTALLATION

CONNECTION OF LINCOLN ELECTRIC
WIRE FEEDERS
Shut off Welder before making any electrical con-
nections.
-------------------------------------------------------------
The LN-15™ Across-the-Arc model, LN-25™ with or
without an internal contactor, and LN-25™ PRO may
be used with the BIG RED™ 600.
1. Shut the welder off.
2. For electrode Positive, connect the electrode cable
from the wire feeder to the “+” terminal of the
welder and work cable to the “-” terminal of the
welder. For electrode Negative, connect the elec-
trode cable from the wire feeder to the “-” terminal
of the welder and work cable to the “+” terminal of
the welder.
3. Set the CV/CC mode of the wire feeder to CC.
(Refer to wire feeder operator manual for details on
setting the wire feeder in the CC mode and for set-
ting welding parameters).
4. Attach the single lead from the front of the wire
feeder to work using the spring clip at the end of
the lead. This is a sense lead to supply current to
the wire feeder motor; it does not carry welding
current.
5. When the gun trigger is closed, the current sensing
circuit will cause the wire to begin to feed and the
welding process is started.
NOTE:
The LN-25™ (K444-1) Remote Control Module
(K431) and Remote Cable (K432) cannot be
used with the BIG RED™ 600 See the appro-
priate connection diagram in
Section F.
If you are using an LN-25™ without an internal
contactor, the electrode will be energized when
the BIG RED™ 600 is started.
-------------------------------------------------------------
The Wire Feeder sensor has full OCV potential
between spring clip and work return. Turn
machine off when attaching spring clip.
-------------------------------------------------------------
Lincoln Electric does NOT recommend constant
current semiautomatic welding for applications
which need to meet specified weld metal chemical
or mechanical property requirements or weld
quality requirements.
