A.POWER SWITCH

-A two-position toggle switch.Controls the input power to the CV-400-I.

B.VOLTAGE ADJUST

-Controls the CV-400-I output voltage.

C.THERMAL PROTECTION INDICATION LIGHT

-Indicates that the protection thermostat has activated. The digital meter will display "E10" when this occurs. When the light turns off, the machine will be capable of supplying welding output power again.

NOTE: Leaving the power switch in the "ON" posi- tion will result in the most rapid cooling.

D.VOLTS/AMPS SWITCH

-Selects either output current or arc voltage to be displayed on the digital meter.

E.DIGITAL VOLTMETER/AMMETER

-Displays the CV-400-I output current, or the arc voltage.

NOTE: Due to voltage drops in the welding cables and at cable connection points, the actual arc voltage may be lower than that displayed on the voltmeter. Use welding cables of the proper capacity and make sure all connec- tions are tight to minimize this effect.

F. 42 VOLT CIRCUIT BREAKER

-Protects the 42 volt 41-42 circuit in the wire feeder receptacle from overloads and shorts. If this circuit breaker opens, the CV-400-I will work normally. However, any equipment powered by the 42 volt circuit will not work.

G. 115 VOLT CIRCUIT BREAKER

-Protects the 115 volt 31-32 circuit in the wire feeder receptacle from overloads and shorts. If this circuit breaker opens, the CV-400-I will work normally. However, any equipment powered by the 115 volt circuit will not work.

H. LOCAL/REMOTE SWITCH

-Determines whether the welding voltage is controlled at the CV-400-I, or controlled remotely by a remote output control (such as a K857).
