DIGITAL VOLTMETER AND AMMETER.
W hith "contactor off". Voltmeter display PRESET voltage and ammeter is turn off.
W hith "contactor on". Voltmeter and ammeter display actual output voltage and
amperage, ammeter remains off if current is zero amperes.
W hile 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. W hile welding this
control can be adjusted.
