VANTAGE 400
Connection of the LN-25 to the VANTAGE 400
Shut off welder before making any electrical
connections.
----------------------------------------------------------------------------
The LN-25 with or without an internal contactor may be used
with the VANTAGE 400. 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.
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, con-
nect 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 VANTAGE 400 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 VANTAGE 400 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 weld-
ing is resumed.
If you are using an LN-25 without an internal contactor, the
electrode will be energized when the VANTAGE 400 is started.
