CONNECTING THE LN-7 TO THE IDEALARC
DC-400 (14-PIN AMPHENOL)
1. Disconnect main AC input power to the Idealarc
DC-400.
2. Set the POWER toggle switch to the OFF (0) posi-
tion.
3. Connect the electrode cable from the K584-XX
Input Cable Assembly to the “+” terminal of the
welder and to the LN-7 wire feeder. Connect the
work cable to the “-” terminal of the welder.
Reverse this hookup for negative polarity.
NOTE: Welding cable must be sized for the current
and duty cycle of the application.
4. Connect K584-XX Input Cable between the DC-
400 and the LN-7. See Figure C.7.
5. Set the welder VOLTMETER toggle switch to the
desired polarity, either DC (-) or DC (+).
6. Set the MODE switch to a CV (constant voltage)
position at the welder.
7. Adjust wire feed speed at the LN-7 and set the
welding voltage with the OUTPUT CONTROL.
NOTE: If optional remote control is used, place the
OUTPUT CONTROL and the OUTPUT TERMI-
NALS switch in the “Remote” position.
