IDEALARC® DC-600 VRD

GENERAL DESCRIPTION

The IDEALARC® DC-600 VRD includes a proprietary design which is
available  in  certain  arc  welding  power  sources  such  as  the  DC  600
and 400. This internal circuitry applies a high frequency, low voltage
signal through the Electrode and Work terminals, while disabling the
output  of  the  power  source.  The  OCV  (  open  circuit  voltage)  during
this  period  is  approximately  2  Volts  RMS  at  70kHz.  When  an
Electrode to Work load of 100 ohms or less is applied, the output of
the  power  source  is  enabled,  allowing  normal  welding  operation.
When  the  output  load  is  removed,  within  0.3  seconds,  the  output  is
again disabled reducing the OCV to approximately 2 Volts RMS

The  IDEALARC®  DC-600  VRD  is  an  SCR  controlled  three  phase
welding and cutting power source.  It uses a single range potentiome-
ter 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  VRD  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 Air Carbon Arc Cutting

Process (AAC)

• Constant Voltage (CV) Submerged Arc
• Constant Voltage (CV) Innershield (also used for FCAW/GMAW)

Two VRD models are available:

• Domestic - 230/460/575V 60 Hertz model
• Export-415V   50/60 Hertz model

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  disconnecting  the  wire  feeder  equipment  control,
electrode, and work leads.

RECOMMENDED  PROCESSES AND  EQUIP-
MENT

The IDEALARC® DC-600 VRD 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  VRD  is  provided  with  a  three  position
mode switch that selects CV Innershield, CV Submerged Arc, or CC
Stick.

The IDEALARC® DC-600 VRD can be easily connected to wire feed-
ing 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

• No large output mechanical contactors or Solid State switches such

as SCR’s, etc; are added to the Electrode to Work output circuit.

• “Tamper Resistant” design. Circuitry is built into power source, not

an exterior package which could easily be tampered with.

• No reduction of power source output rating. This feature does not

affect the rating of the power source.

• Self diagnostics upon machine power up.  Indicator lights are test-

ed. 

• Green lamp on when weld voltage is less than 30 volts. If weld volt-

age exceeds 30 volts, Green lamp turns off and Red lamp turns on.

• Output is disabled if OCV > 50 volts is sensed.

• Excellent  arc  characteristics  for  optimum  constant  voltage  sub-

merged 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 con-

tinuous control.

• Output  Control  Switch  that  provides  simple  switching  from  local  to

remote control.

• Output Terminals Switch to energize output terminals either local or

remote.

• White  neon  pilot  light  to  confirm  that  the  Input  Contactor  is  ener-

gized.

• 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 mod-

els, 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 acci-

dentally 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  over-

loads.

• Input  line  voltage  compensation  to  provide  an  essentially  constant

output.

• SCR electronically controlled welder output provides 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  perfor-

mance 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  dam-

age.

• 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.
