OPERATING STEPS

The following procedures are for using the IDEAL-
ARC DC-600 in the local control mode of operation.
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. Set the CONTROL CIRCUIT POLARITY SWITCH
to the appropriate position.
- Set toggle to "Electrode Negative" position if the
electrode is connected to the negative (-) output
terminal.
- Set toggle to "Electrode Positive" position if the
electrode is connected to the positive (+) output
terminal.
3. Set the WELDING MODE SWITCH to welding
process being used.
- CV Submerged Arc
- CV Innershield
- CC Stick
4. Push the ON/OFF PUSH BUTTON to the ON
position
- The red neon light glows.
- The fan starts.
5. Set Output Control Potentiometer to desired volt-
age or current.
6. Make the weld (NOTE: Terminal #2 and #4 must
be connected together to energize the machine
output).
OPERATION
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/Other Open Arc Processes:
Use the CV Innershield mode.
2. Submerged Arc Welding: 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 pro-
duces the best welding results.
3. Air/Carbon Arc Cutting / Stick Welding / High
Current, Large Puddle Submerged Arc Welding:
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 car-
bon being used or the process, turn the poten-
tiometer 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 cir-
cuiting pulses.
