3.OUTPUT CONTROL

This control provides continuous control of the machine’s output voltage and current from mini- mum to maximum (typical full pot range between 15 to 44 volts and 90 to 750 amps) as it is rotated


clock-wise.	Voltage or current control is deter-
mined by setting of Mode Switch (CV or CC).
4. OUTPUT TERMINALS ON/REMOTE Switch
When this switch is in the REMOTE “			” posi-
tion, the IDEALARC® DC-600 VRD’s output termi-
nals will be electrically “cold” until a remote device
such as a wire feeder closes the #2 and #4 circuit
in the MS-receptacle or terminal strip (T.S.2).
When this switch is in the ON “		” position the

machine’s output terminals will be electrically energized all the time.

5. LOCAL/REMOTE Switch

When this switch is set to the LOCAL “ “ posi- tion, control of the output voltage and current is via the OUTPUT CONTROL on the IDEALARC® DC- 600 VRD’s control panel. When this switch is set

to the REMOTE “ ” position, control is through a remote source such as a wire feeder via the #75, #76, and #77 leads in the MS-receptacle or terminal strip (T.S.1).

6.Mode Switch

This switch allows for selecting the welding process to be used:

CC STICK-for SMAW and AAC

CV SUbMERGED ARC- for SAW

CV INNERSHIELD- for FCAW and GMAW

7.115VAC Duplex Receptacle (60 Hertz Models) This receptacle provides up to 15 amps of 115 VAC auxiliary power.

8.115VAC 15 Amp Circuit breaker

This breaker protects the 115 VAC auxiliary cir- cuits located in the duplex receptacle, terminal strip (T.S.2) and MS-receptacle.

9.42VAC 10 Amp Circuit breaker

This breaker protects the 42VAC auxiliary circuits located in the terminal strip (T.S.2) and MS-recep- tacle.

10.14 Pin MS-Receptacle

This connector provides easy connection for a wire feeder control cable. It provides connections for auxiliary power, output switching, remote out- put control, wire feeder voltmeter sense lead and ground. Refer to 14 Pin MS Type Receptacle in the Installation Section for information about the circuits made available at this receptacle.

11.Terminal Strip Cover Panel

Rotate this panel to gain access to the circuits made available at the two terminal strips (T.S.1 and T.S.2). These terminal strips contains the same circuits as the 14 pin MS-receptacle. There is a box connector adjacent to this cover for rout- ing leads to the terminal strips.

12.Negative Output Terminal

This output terminal is for connecting a welding cable. To change welding polarity and for proper welding cable size refer to Electrode and Work Cables in the Installation Section.

13.Positive Output Terminal

This output terminal is for connecting a welding cable. To change welding polarity and for proper welding cable size refer to Electrode and Work Cables in the Installation Section.

14.VRD Lights

When VRD is active, in CC mode, these lights illuminate based on the stud voltage while weld- ing. The green light will be on when the welding voltage is under 30 volts and the red light light will turn on when the voltage is 30 volts or greater.

15.Thermal Protection Light (Only on Codes 11707 and 11725)

An amber light on the machine control panel indi- cates when either of the two protective ther- mostats has opened. Output power will be dis- abled temporarily. Thermostat will automatically reset when the machine cools to an acceptable operating temperature.

42 volt AC auxiliary power, as required for some wire feeders, is available through the wire feeder MS- receptacle. A 10 amp circuit breaker protects the 42 volt circuit from overloads.

On Codes 11598 and 11613, IDEALARC® DC-600 VRD machines supply 115 volt AC auxiliary power through the wire feeder receptacle. A 15 amp circuit breaker protects the 115 volt circuit from overloads.
