source output.

DIGITAL METER SWITCH - Select either "A" for amps
or "V" for volts to display welding current or voltage on
the meter.
When welding current is not present, the meter will dis-
play the set current for the CC modes or the set volt-
age for the CV modes. This set reading is an indication
of machine control setting. For a more precise process
reading, read meter during actual welding.
