IDEALARC® DC-600
GENERAL DESCRIPTION
The IDEALARC® DC-600 is an SCR controlled three
phase welding and cutting power source. It uses a
single range potentiometer to control:
• Submerged Arc Semi-Automatic or Automatic
Welding
• Open Arc Semi-Automatic or Automatic Welding
• Stick Welding
• Air/Carbon Arc Cutting (Carbon Rod Sizes up to
3/8” Diameter)
The IDEALARC® DC-600 has a three-position
Welding Mode Switch to enable the user to operate in
one of three modes:
• Constant Current (CC) Stick (also used for AAC)
• Constant Voltage (CV) Submerged Arc
• Constant Voltage (CV) Innershield (also used for
FCAW/GMAW)
Three models are available:
• Domestic - all 60 Hertz models except
230/460/575V.
• Canadian-230/460/575V 60 Hertz models
• Export-50/60 Hertz models
The optional Multi-Process Switch allows the user to
switch between semi-automatic or automatic welding
and stick welding or air/carbon arc cutting without dis-
connecting the wire feeder equipment control, elec-
trode,and work leads.
RECOMMENDED PROCESSES AND
EQUIPMENT
The IDEALARC® DC-600 is designed for GMAW
(MIG), FCAW, and submerged arc (SAW) within the
capacity of the machine. It can also be used for stick
welding (SMAW) and for air carbon arc (AAC) cutting
with carbon rods up to 3/8" diameter.
The IDEALARC® DC-600 is provided with a three
position mode switch that selects CV Innershield, CV
Submerged Arc, or CC Stick.
The IDEALARC® DC-600 can be easily connected to
wire feeding equipment, including:
• Semi-automatic wire feeders LN-7, LN-7 GMA,
LN-742, LN-8, LN-9, LN-9 GMA, LN- 10, LN-15
LN-23P, LN-25, and DH-10.
• Automatic wire feeders NA-3, NA-5, and NA-5R.
• Tractors LT-56 and LT-7
DESIGN FEATURES AND
ADVANTAGES
• Excellent arc characteristics for optimum constant
voltage submerged arc and Innershield welding
performance.
• A control circuit designed to provide good starting
for a large variety of processes and procedures.
• Output Control Potentiometer that provides easy
single range continuous control.
• Output Control Switch that provides simple switch-
ing from local to remote control.
• Output Terminals Switch to energize output termi-
nals either local or remote.
• White neon pilot light to confirm that the Input
Contactor is energized.
• DC Ammeter and Voltmeter
• 42VAC 10 Amp auxiliary power available for the
wire feeder, circuit breaker protected.
• Single MS-type (14 pin) connector for wire feeder.
• 115VAC 15 Amp auxiliary power available for the
wire feeder, circuit breaker protected.
• 115VAC 15 Amp duplex plug receptacle available
on 60 Hertz models, circuit breaker protected.
• Multi-functional terminal strip for easy connection
of wire feeding control cables.
• Recessed output terminals to avoid any person or
object from accidentally coming into contact with
the output terminals and labeled " + " and " - " for
easy identification.
• Thermostatically protected power source.
• Electronic protection circuit to protect power
source against overloads.
• Input line voltage compensation to provide an
essentially constant output.
• SCR electronically controlled welder output pro-
vides extra long life, especially for highly repetitive
welding applications.
• Solid state 2 and 4 circuit for extra long life.
• Two circuit solid state control system provides
maximum performance and circuit protection.
• Low profile case provides maximum use of space.
• Convenient access to all controls.
• Output lead strain relief loops to prevent terminal
and cable damage.
• Easily removed case side, even when stacked.
• Outdoor operation because enclosure is designed
with air intake louvers that keep dripping water
from entering the unit. Transformer, SCR bridge,
and choke have special corrosion resistant paint
for added protection.
