Fault code display. The first fault to occur will be displayed for three
seconds. The display will cycle through fault codes for all faults that
persist after the initial three-second period are displayed for 1 sec-
ond each.
Weld mode is changing
If actively welding, the displays are arc current and arc voltage. If
not actively welding, the display will show work point.

blinked for 5 seconds following a weld. If the work point changes
during this 5 second period, the display will revert to the above
