Error Indications

Error conditions are indicated by a "HLP" message on the display, or by the blinking of the Red LED on Motor
Board PC1. To view the Red LED, turn Off power source, remove shroud, and turn power source On. The Red
LED blinks in a 2.5 second cycle. The number of blinks in this period indicates the type of error. If an error condi-
tion does not exist on the motor board, the Red LED is on steady.

Communication Error

The communication error occurs 2.5 seconds after a loss of communication between the motor board and the
meter board. The user may continue to weld with this error. The error may be cleared by turning power Off, wait-
ing a minimum of two seconds, and turning power On.
Motor Overload Error
The motor overload error can indicate that the motor has been drawing too much current for too long, To remedy
this, reduce the wire feed speed or the wire feeder torque load/duty cycle. The error may be cleared by turning
power Off, waiting a minimum of two seconds, and turning power On.
Bus Bar Overheat Error
The bus bar overheat error can be caused by the arc drawing too much current for too long. To remedy this, re-
duce the weld amperage or duty cycle.
