WaRNING
Connection of the LN-25 to the VaNtaGe® 400
(aU) shut off welder before making any electrical
connections.
------------------------------------------------------------------------
The LN-25 with or without an internal contactor may
be used with the VANTAGE® 400 (AU). See the
appropriate connection diagram in Section F.
NOte: The LN-25 (K431) Remote Control Module
and (K432) Remote Cable are not recommended for
use with the VANTAGE® 400 (AU).
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 VANTAGE® 400 (AU)
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 VANTAGE® 400 (AU)
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.
CaUtION
If you are using an LN-25 without an internal con-
tactor, the electrode will be energized when the
VaNtaGe® 400 (aU) is started.
