OPERATION
B-8
c. Set NA-3 Start Board current and voltage
as close to the welding procedure current
and voltage as possible.
NOTE: The Start Board current and volt-
age should be as close as possible to the
welding procedure current and voltage,
while still getting satisfactory starts.
d. Set the start time to as low a time as possi-
ble while still getting satisfactory starts.
7. Start and make the weld.
IDEALARC DC-1000 POWER SOURCE
SETTING WHEN CONNECTED TO NA-5
AUTOMATIC WIRE FEEDER
When using the IDEALARC DC-1000 with the NA-5
automatic wire feeder, set the controls on the IDE-
ALARC DC-1000 as follows for the best performance:
1. Turn OFF main AC input power supply to the IDE-
ALARC DC-1000.
2. Connect the electrode cables to terminal
polarity to be used.
3. Set the CONTROL CIRCUIT POLARITY SWITCH
to the same polarity as the electrode cable con-
nection.
4. Set the OUTPUT CONTROL SWITCH to
REMOTE.
5. Set the IDEALARC DC-1000 WELDING MODE
SWITCH to the position that matches the welding
process being used.
a. For submerged arc welding, set WELDING
MODE SWITCH TO CV SUBMERGED
ARC position.
b. For all open arc welding processes set
WELDING MODE SWITCH TO CV
INNERSHIELD® position.
6. Set the Open Voltage Control four volts higher
than the welding voltage, and the inch speed at
1/2 the welding wire feed speed for the initial test
weld.
7. Refer to NA-5 Operator’s Manual for instructions
on how to use the NA-5.
LN-8 SEMI-AUTOMATIC WIRE FEEDER
To use the LN-8 Semi-Automatic Wire Feeder with
IDEALARC DC-1000
1. Set the IDEALARC DC-1000 WELDING MODE
SWITCH to either CV Innershield® mode or CV
Submerged Arc mode depending on the welding
process being used.
2. Set the IDEALARC DC-1000 OUTPUT CONTROL
SWITCH to the REMOTE position.
3. Set the LN-8 Welding Mode Switch to the CV
position. The LN-8 Welding Mode Switch is locat-
ed on the variable voltage VV (CC) board.
4. Refer to the LN-8 Operator’s Manual for instruc-
tions on how to use the LN-8.
LN-7 AND LN-9 SEMI-AUTOMATIC WIRE
FEEDERS OR OTHER CONSTANT WIRE
FEEDERS
To use the LN-7, LN-9, or other constant wire feed
speed semi-automatic wire feeders with IDEALARC
DC-1000
1. Set the IDEALARC DC-1000 WELDING MODE
SWITCH to either CV Innershield® mode or CV
Submerged Arc mode depending on the welding
process being used.
NOTE: These semi-automatic wire feeders cannot be
used in the VV (CC) mode.
2. Set the IDEALARC DC-1000 OUTPUT CONTROL
SWITCH.
a. LN-7: Use either an optional K775 Remote
Control Box Assembly or set the IDE-
ALARC DC-1000 OUTPUT CONTROL
SWITCH in the Local position.
b. LN-9: Refer to the LN-9 Operator’s Manual
for instructions on how to use the LN-9.
