These indicate the actual voltage and current
readings at the output terminals of the welding
machine. The current meter should read ‘0’ except
when welding is actually taking place. The voltage
meter will indicate output voltage during welding
and the welding open circuit voltage when the
machine is powered up but not welding. In MIG
mode the open circuit voltage will only appear
once the torch is triggered to activate the circuit,
LCD Current & Voltage Display Meters
in MMA and Lift TIG mode, the open circuit voltage
will show on the display continuously. The digital
meters are very sensitive and accurate, so it is not
abnormal to observe some small uctuations on
them when the machine is at rest.
