REMOTE CONTROL OF MACHINE
OPERATION
The toggle switch on the control panel labeled
“Remote - Panel” gives the operator the option of con-
trolling the machine output from a remote location. If
in the Remote position a wire feeder with remote con-
trol capabilities or a remote control device such as a
K775 must be connected to terminals 75, 76, and 77.
Refer to Accessories Section for wire feeder remote
information.
WELDING PROCEDURE
RECOMMENDATIONS
Select Welding Mode Switch position based on type of
welding to be done.
1. Innershield Welding (FCAW)/MIG (GMAW)
Welding: Use the CV INNERSHIELD mode.
2. Submerged Arc Welding (SAW): Use the CV
SUBMERGED ARC mode. If performing high
speed welding, switch between the CV
Submerged Arc and the CV Innershield mode and
use the mode that produces the best welding
results.
3. Air/Carbon Arc Cutting (AAC) / Stick Welding
(SMAW) / High Current, Large Puddle Submerged
Arc Welding (SAW): Use the CC STICK mode.
When the IDEALARC® DC-600 is used for
Air/Carbon Arc cutting, the OUTPUT CONTROL
potentiometer should be set to "9" initially. Based
on the size of the carbon being used or the
process, turn the potentiometer to a lower setting
as required by the process. You can use carbon
rods up to 3/8" in diameter at currents as high as
750 amps with excellent arc control. The welder
protection circuit protects the machine from
extremely high short circuiting pulses.
SEMI-AUTOMATIC AND
AUTOMATIC WIRE FEEDING WITH
THE IDEALARC® DC-600 AND WIRE
FEEDERS
When using the IDEALARC® DC-600 with semi-auto-
matic or automatic wire feeding equipment and for
stick welding or air/carbon arc cutting, it is recom-
mended that the optional MULTI-PROCESS SWITCH
be used. This switch permits you to easily change the
polarity of the connected wire feeding equipment or
switch to stick welding or air/carbon arc cutting.
B-6 OPERATION B-6
The power source circuitry is protected from faults on
leads 75, 76, or 77. If any of these leads are connect-
ed to either the positive or negative output leads, the
IDEALARC® DC-600 will either shut down completely
(input contactor opens and white POWER light stays
illuminated), or will operate at minimum output thus
preventing any damage to the IDEALARC® DC-600. If
IDEALARC® DC-600 shuts down, it must be manually
started by resetting the POWER ON/OFF toggle
switch.
OPERATING STEPS
The following procedures are for using the IDE-
ALARC® DC-600 in the local control mode of opera-
tion. For remote control of the machine, see the
Remote Control of Machine Operation section.
Before operating the machine, make sure you have all
materials needed to complete the job. Be sure you
are familiar with and have taken all possible safety
precautions before starting work. It is important that
you follow these operating steps each time you use
the machine.
1. Turn on the main AC power supply to the
machine.
2. Connect the #21 work lead to either + or - on ter-
minal strip (T.S.2).
3. Set the Welding Mode switch to welding process
being used:
• CC STICK (for SMAW and AAC)
• CV SUBMERGED ARC (for SAW)
• CV INNERSHIELD (for FCAW and GMAW)
4. Turn the POWER ON/OFF Toggle Switch to the
“ON” position
• The white pilot light glows.
• The fan starts.
5. Set OUTPUT CONTROL Potentiometer to desired
voltage or current.
6. Set the OUTPUT TERMINALS switch to either
“ON” ( output terminals energized) or “REMOTE”
(output terminals energized when #2 and #4
closed by remote device such as wire feeder)
7. Make the weld.
