Error Indications - Error conditions are indicated by a "HLP" message on the display, or by the blinking of the Red LED on Motor Control Board
(PC1). To view the Red LED, turn Off power source, remove shroud, and turn power source On. The number of blinks in this period indicates the
type of error. If an error condition does not exist on the Motor Control Board (PC1), the Red LED is on steady.
Communication Error - The communication error occurs 2.5 seconds after a loss of communication between the Motor Control Board (PC1) and
the meter board PC20. The user may continue to weld with this error. The error may be cleared by turning power Off, waiting a minimum of two
seconds, and turning power On.
Trigger Error - The trigger error occurs if the user has fed approximately 35 feet (10.7 meters) of wire without striking an arc. The error may be
cleared by releasing the trigger.
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, reduce
the weld amperage or duty cycle.
Tach Error - May indicate motor is overloaded. If a tach error occurs, feeder will continue to function. When the trigger is released, a tach error
will be indicated on the front panel, or red LED blinks on Motor Control Board (PC1). The tach error will be cleared when the feeder is re-triggered.
If error persists, have feeder serviced. Tach error may also be generated if DIP switch SW1 on Motor Control Board (PC1) is set incorrectly (See
Section 5-8).

If a welding arc is not established in 3 seconds, after the gun trigger is activated, the unit will feed wire
without energizing the contactor or gas valve. The unit will feed approximately 35 feet (10.7 meters) of
wire, then stop feeding. This is to prevent complete de-spooling of the wire, as in the case of a damaged
gun.
Have Factory Authorized Service Agent check Motor Control Board (PC1).
Replace meter board PC20.
Replace meter board PC20.
Arc voltage on the meter board PC20 will show weld voltage at the feeder. Due to voltage drops in the
weld cables, arc voltage at the feeder will not match arc voltage at the welding power source. Due to aver-
aging of arc voltage, if weld time is less than 8 seconds the displayed arc voltage at the feeder may not
be accurate.
Check Motor Control (PC1) and connections, replace if necessary.
Amperage displayed at feeder is approximate. Refer to power source for actual amperage
(see Section 5-9).
Check DIP switch settings on meter board PC20 (see Section 5-9).
Check transducer HD1 and connections, and replace if necessary.
Check Motor Control (PC1) and connections, replace if necessary.
Check DIP switch settings on meter board PC20 (see Section 5-9).
Check Motor Control (PC1) and connections, replace if necessary.
