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 

LCD Current & Voltage Display Meters

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, 

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 fluctuations on 

them when the machine is at rest.
