OPERATION
B-6
IDEALARC DC-600
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 pre-
cautions 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 Innershield
- CV Submerged Arc
- VV (CC)
4.
Push the ON/OFF PUSH BUTTON to the ON posi-
tion
- 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).
REMOTE CONTROL OF MACHINE
OPERATION
The toggle switch on the control panel labeled “Output
Control at DC-600” — “Output Control Remote” gives
the operator the option of controlling the machine out-
put from a remote location. If in the Remote position a
wire feeder with remote control 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 produces
the best welding results.
3.
Air/Carbon Arc Cutting / Stick Welding / High
Current, Large Puddle Submerged Arc Welding:
Use the VV (CC) mode. When the IDEALARC DC-
600 is used for Air/Carbon Arc cutting, the OUT-
PUT 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 cur-
rents as high as 750 amps with excellent arc con-
trol. The welder protection circuit protects the
machine from extremely high short circuiting pulses.
