For connection diagrams and instructions for connect-
ing an NA-3 Welding System to the AIR VANTAGE®
500 CUMMINS, refer to the NA-3 Welding System
instruction manual. The connection diagram for the
LN-8 can be used for connecting the NA-3.
• Set the Wire Feeder Voltage Switch to 115V.

The LN-25 with or without an internal contactor may be
used with the AIR VANTAGE® 500 CUMMINS. See the
appropriate connection diagram in Section F.
#$): The LN-25 (K431) Remote Control Module and
(K432) Remote Cable are not recommended for use
with the AIR VANTAGE® 500 CUMMINS.

2. 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
electrode Negative, connect the electrode cable
from the LN-25 to the "-" terminal of the welder and
work cable to the "+" terminal of the welder.
3. 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 control lead to supply current to the wire
feeder motor; it does not carry welding current.
4. Set the MODE switch to the "CV-WIRE " position.
5. Set the "WELD TERMINALS" switch to "WELD
TERMINALS ON"
6. Set the "ARC CONTROL" knob to "0" initially and
adjust to suit.
7. Set the "IDLE" switch to the "AUTO" position. When
not welding, the AIR 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.
8. When the gun trigger is closed, the current sensing
circuit will cause the AIR VANTAGE® 500 CUM-
MINS engine to go to the high idle speed, the wire
will begin to feed and the welding process started.
When welding is stopped, the engine will revert to
low idle speed after approximately 12 seconds
unless welding is resumed.
