CONNECTION OF THE LN-25 TO THE
VANTAGE 500 CUMMINS
The LN-25 with or without an internal contactor may
be used with the VANTAGE 500 CUMMINS. See the
appropriate connection diagram in the DIAGRAMS
section.
NOTE: The LN-25 (K431) Remote Control Module
and (K432) Remote Cable are not recommended for
use with the VANTAGE 500 CUMMINS.
• Shut the welder off.
• For electrode Positive, connect the electrode cable
from the LN-25 to the “+” terminal of the welder and
work cable to the “-” terminal of the welder. For elec-
trode Negative, connect the electrode cable from the
LN-25 to the “-” terminal of the welder and work
cable to the “+” terminal of the welder.
• Attach the single lead from the front of the LN-25 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.
• Set the SELECTOR switch to the “CV-WIRE” posi-
tion.
• Set the “WELDING TERMINALS” switch to “WELD
TERMINALS ON”
• Adjust the “ARC CONTROL” knob to desired crisp-
ness. Generally, welding is best if the “ARC CON-
TROL” is set to SOFT for MIG and CRISP for
INNERSHIELD. You may however, want to start in
the middle and adjust (as needed) from there.
• Set the “IDLE” switch to the “AUTO” position. When
not welding, the VANTAGE 500 CUMMINS engine
will be at the low idle speed. If you are using an LN-
25 with an internal contactor, the electrode is not
energized until the gun trigger is closed.
If you are using an LN-25 without an internal con-
tactor, the electrode will be energized when the
VANTAGE 500 CUMMINS is started.
------------------------------------------------------------------------
• When the gun trigger is closed, the current sensing
circuit will cause the wire to begin to feed and the
welding process is started.
CONNECTION OF AN NA-3 AUTOMATIC
WELDING SYSTEM TO THE VANTAGE 500
CUMMINS
For connection diagrams and instructions for connect-
ing an NA-3 Welding System to the VANTAGE 500
CUMMINS, refer to the NA-3 Welding System instruc-
tion manual. The connection diagram for the LN-8 can
be used for connecting the NA-3.
• Set the Wire Feeder voltmeter to the proper polarity of the
electrode.
CONNECTION OF MAGNUM SC SPOOL
GUN TO THE VANTAGE 500 CUMMINS
(SEE SECTION F)
CONNECTION OF PRINCE XL SPOOL
GUN TO THE VANTAGE 500 CUMMINS
Connection of the Prince XL Spool Gun requires the
use of the K1849-1 Adapter Module.
• Shut the Welder off.
• For electrode Positive, connect the electrode cable
to the "+" terminal of the welder and work cable to
the "-" terminal of the welder. For electrode
Negative, connect the electrode cable "-" terminal
of the welder and work cable to the "+" terminal of
the welder.
• Connect the Control Cable of the Spool Gun to the
Adapter Module and connect the Control Cable of
the Adapter Module to the Welder.
• Connect the Gas Hose.
• Set the MODE switch to the "CV-WIRE " position.
• Set the "WELD TERMINALS" switch to "WELD
TERMINALS ON".
• Set the "ARC CONTROL" knob to "0" initially and
adjust to suit.
• Set the "IDLE" switch to the "High" position
