CONNECTION OF THE LN-25 TO THE VANTAGE 500 CUMMINS

The LN-25 with or without an internal contactor may be used with the VANTAGE 500 CUMMINS. 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 VANTAGE 500 CUMMINS.

•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 elec- trode 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” posi- tion.

•Set the “WELDING TERMINALS” switch to “WELD

TERMINALS ON”

•Adjust the “ARC CONTROL” knob to desired crisp- ness. Generally, welding is best if the “ARC CON- TROL” 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 VANTAGE 500 CUMMINS 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.

CAUTION

If you are using an LN-25 without an internal con- tactor, the electrode will be energized when the VANTAGE 500 CUMMINS 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 VANTAGE 500 CUMMINS

For connection diagrams and instructions for connect- ing an NA-3 Welding System to the VANTAGE 500 CUMMINS, refer to the NA-3 Welding System instruc- tion manual. The connection diagram for the LN-8 can be used for connecting the NA-3.

•Set the Wire Feeder voltmeter to the proper polarity of the electrode.

CONNECTION OF MAGNUM SC SPOOL GUN TO THE VANTAGE 500 CUMMINS (SEE SECTION F)

CONNECTION OF PRINCE XL SPOOL GUN TO THE VANTAGE 500 CUMMINS

Connection of the Prince XL Spool Gun requires the use of the K1849-1 Adapter Module.

•Shut the Welder off.

•For electrode Positive, connect the electrode cable to the "+" terminal of the welder and work cable to the "-" terminal of the welder. For electrode Negative, connect the electrode cable "-" terminal of the welder and work cable to the "+" terminal of the welder.

•Connect the Control Cable of the Spool Gun to the Adapter Module and connect the Control Cable of the Adapter Module to the Welder.

•Connect the Gas Hose.

•Set the MODE switch to the "CV-WIRE " position.

•Set the "WELD TERMINALS" switch to "WELD

TERMINALS ON".

•Set the "ARC CONTROL" knob to "0" initially and adjust to suit.

•Set the "IDLE" switch to the "High" position
