CONNECTION OF AN NA-3 AUTOMATIC

WELDING SYSTEM TO THE VANTAGE®

575 CUMMINS

For connection diagrams and instructions for connect-

ing an NA-3 Welding System to the VANTAGE® 575

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 Voltage Switch to 115V.

CONNECTION OF MAGNUM SC SPOOL

GUN TO THE VANTAGE® 575 CUMMINS

(SEE SECTION F)

Spool Gun (K487-25) and Cobramatic to VAN-

TAGE® 575 CUMMINS.

• Shut the welder off.

• Connect per instructions on the appropriate connec-

tion diagram in Section F.

CONNECTION OF THE LN-25 TO THE

VAN-

TAGE® 575 CUMMINS

Shut off welder before making any electrical con-

nections.

--------------------------------------------------------------------------

The LN-25 with or without an internal contactor may be

used with the

VANTAGE® 575 CUMMINS

. 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® 575 CUMMINS

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

VANTAGE® 575 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.

8. When the gun trigger is closed, the current sensing

circuit will cause the

VANTAGE® 575 CUMMINS

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

VANTAGE® 575 CUMMINS

is started.
