B.1 for the location of each control and connection.
FIGURE B.1- CV-300 Operator Controls and
Connections.
1. ON/OFF POWER SWITCH
- Two position
toggle switch that controls input power to the
machine.
2. WIRE FEEDER VOLTMETER SWITCH
-
This switch selects the polarity of the wire feeder
voltmeter, if so equipped. When welding electrode
positive (MIG, Outershield and some Innershield
processes) set the switch to "+".
When welding electrode negative (most Innershield
electrodes), set the switch to "-".
NOTE: This switch has no effect on the welding polar-
ity. In fact, if the wire feeder being used does not have
a voltmeter, the setting of this switch has no effect.
3. LOCAL/REMOTE SWITCH
- When switch is
in the LOCAL position, the welding voltage is con-
trolled at the CV-300. When the switch is the
REMOTE position, the welding voltage is con-
trolled remotely by a remote output control.
4. VOLTAGE ADJUSTMENT CONTROL
KNOB
- Controls the CV-300 output voltage.
