DIGITAL VOLTMETER AND AMMETER.
Whith "contactor off". Voltmeter display PRESET voltage and ammeter is turn off.
Whith "contactor on". Voltmeter and ammeter display actual output voltage and
amperage, ammeter remains off if current is zero amperes.
While welding, the meters measure and display the output arc voltage and amperage.
once extinguished the arc, the digital meters retained the arc values approx 4 sec.,
subsequently shown PRESET value.

* VOLTAGE ADJUSTMENT control.
To increase arc voltage output, turn control clockwise.
Voltmeter value changes as control is turned. While welding this
control can be adjusted.
