Displays

Description

Scrolling dash

Appears at power up while the machine is going through its self configu-
ration

"Err" "####"

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

"----" "####"

A constant voltage weld mode is selected, machine output is off.
The numeric value in the right display is the workpoint.

"####" "----"

A constant current weld mode is selected, machine output is off.
The numeric value in the left display is either the workpoint or a
workpoint limit, depending on the weld mode and remote configura-
tion.

"####" "####"(on steady) machine output is on. Left display is current, right display is voltage.

If actively welding, the displays are arc current and arc voltage. If
not actively welding, the display will show workpoint.

"####" "####" (blinking)

weld just finished

–

the average arc voltage and current will be

blinked for 5 seconds following a weld. If the workpoint changes dur-
ing this 5 second period, the display will revert to the above mode.
