500(AU) KUBOTA
For connection diagrams and instructions for connect-
ing an NA-3 Welding System to the AIR VANTAGE
®
500(AU) KUBOTA, 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.

CONNECTION OF THE LN-25 TO THE AIR
VANTAGE
®
500(AU) KUBOTA.
Shut off welder before making any electrical con-
nections.
--------------------------------------------------------------------------------
The LN-25 with or without an internal contactor may
be used with the AIR VANTAGE
® 500(AU) KUBOTA .
See the appropriate connection diagram in Section F.
1. Shut the welder off.
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 elec-
trode 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(AU)
KUBOTA 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 sens-
ing circuit will cause the AIR VANTAGE ® 500(AU)
KUBOTA 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.
If you are using an LN-25 without an internal con-
tactor, the electrode will be energized when the
AIR VANTAGE
® 500(AU) KUBOTA is started.
