Where one of the TIG welding modes has been selected, the right-hand display
reads "0.0" before the start of welding. Where the "Rod electrode (MMA) welding"
mode has been selected, there is a 3-second time lag before the value for the open-
circuit voltage "50V" is displayed.
Important! The value of 50 V indicated where the "Rod electrode (MMA)" process
has been selected refers to the mean value of the pulsed open-circuit voltage.
