Lincoln Electric AIR VANTAGE 500 CUMMINS IM826-A - Manual (Page 17)

CONNECTION OF THE LN-25 TO THE AIR
VANTAGE® 500
The LN-25 with or without an internal contactor may be used with
the AIR VANTAGE® 500. 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 AIR
VANTAGE® 500.
• 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 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.
• 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” position.
• Set the “WELDING TERMINALS” switch to “WELD
TERMINALS ON”
• Adjust the “ARC CONTROL” knob to desired crispness.
Generally, welding is best if the “ARC CONTROL” 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 AIR VANTAGE® 500 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 contactor, the
electrode will be energized when the AIR VANTAGE® 500 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 AIR VANTAGE® 500
For connection diagrams and instructions for connecting an NA-3
Welding System to the AIR VANTAGE® 500, 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.
