DIGITAL VOLTMETER AND AMMETER.
W ith "contactor off". Voltmeter display PRESET voltage and ammeter is turn off.
W ith "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
Use this control to set the arc voltage.
