Vrd(Voltage Reduction Device); Output Remote Control - Shindaiwa DGW300MS Owner's And Operator's Manual

negative( ) dial side and Strong (Crisp) welding arc can be obtained with Arc
Control Dial positive( ) dial side.
(4) ROD SELECTOR (for CC mode)
The equipment incorporates Rod Selector feature.
When the CV/CC Selector Switch is positioned at [CC-STICK, GOUGING], the
welding characteristics can be switched by changing Rod Selector Switch.
[CELLULOSE] mode is suitable for the Cellulose Rods and [OTHERS] mode is
suitable for the Gouging Rods and ordinal rods except cellulose.
5-3. Voltage Reduction Device
The equipment incorporates VRD (Voltage Reduction Device) feature, for the
purpose of protecting an operator from electric shock with welding output.
When the VRD Selector Switch is turned to [ON], the voltage changes to 35V or less
during no welding period.
The equipment is incorporated with
monitoring function of VRD.
When the VRD Selector Switch is turned to
[ON], Green VRD Lamp will be automatically
turned on at [BELOW 35V] side.
When the Red VRD lamp will be turned on at [AT OR ABOVE 35V] side, the welding
voltage is exceeded more than 35V or while the VRD Selector switch is at [TEST]
mode.

5-4. Output Remote Control

The equipment incorporates Optional Output Remote Control feature.
(1) 14-Pin Connector (Wire Feeder Control)
Wire Feeder Control operation is available by connecting the Optional Wire Feeder
to the 14-Pin Connector
(2) Welding Terminals Switch
Wire Feeder Control operation is available by turning the Weld Terminals Switch to
[REMOTE CONTROL] position.
When the Weld Terminals Switch to [WELD TERMINALS ON] position, the welding
voltage is always supplied from machine's welding terminal.
When the Weld Terminals Switch to [REMOTE CONTROL] position, the welding
voltage will be supplied from machine's welding terminal by pressing the wire feeder
torch trigger.
(3) Wire Feeder Voltmeter Selector
The Wire Feeder Voltmeter Switch can change the voltmeter indication polarity
which is equipped on the optional wire feeder.
(4) 42V / 115V Selector
The 42V / 115V Selector Switch can change the supply voltage for the required
output voltage based on the optional wire feeder specification.
