CONNECTION OF THE LN-25 TO THE AIR VANTAGE® 500.

WARNING

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. See the appropri- ate connection diagram in Section F.

NOTE: The LN-25 (K431) Remote Control Module and (K432) Remote Cable are not recommended for use with the AIR VANTAGE® 500.

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 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 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 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 AIR VANTAGE® 500 is started.
