The Lincoln VRD circuit meets the requirements of
AS1674.2-2007, Safety in welding and allied
processes - Electrical, for Category C environments.
Category C environments include coffer dams,
trenches, mines, in rain, etc.
The Lincoln VRD circuit also meets recommendation
of ANSI Z49.1- 2005, Safety in Welding, Cutting and
Allied Processes, for use in electrically hazardous
conditions ( in damp locations or while wearing wet
clothing; on metal structures such as floors, gratings
or scaffolds; when in cramped positions such as sit-
ting, kneeling or lying, if there is a high risk of
unavoidable or accidental contact with the workpiece
or ground ).

OPERATING STEPS

The following procedures are for using the IDE-
ALARC® DC-600 VRD 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.
CV MODE
1. Connect the #21 work lead to either + or - on termi-
nal strip (T.S.2).
2. Turn on the main AC power supply to the machine.
3. Set the Welding Mode switch to welding process
being used:
• 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 and the fan starts.
5. Set OUTPUT CONTROL Potentiometer to desired
voltage.
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.
CC MODE
1. Connect the #21 work lead to either + or - on termi-
nal strip (T.S.2).
2. Turn on the main AC power supply to the machine.
OPERATION
3. Set the Welding Mode switch to welding process
being used:
• CC STICK (for SMAW and AAC)
4. Turn the POWER ON/OFF Toggle Switch to the
"ON" position:
• The white pilot light glows and the fan starts for 1
second.
• The machine continues the 5 second pretest indi-
cated by both red and green VRD lights glowing.
When the red light turns off, the pilot light turns on
and the fan restarts, the machine is ready.
5. Set OUTPUT CONTROL Potentiometer to desired
current.
6. Set the OUTPUT TERMINALS switch to either
"ON" ( output terminals active) or "REMOTE" (out-
put terminals active when #2 and #4 is closed by
remote device such as wire feeder).
7. Make the weld.
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.
