current error.
ERR TACH
The tach error occurs 2 seconds after the
loss of tachometer feedback. The motor
speed is regulated through the monitoring of
voltage and current. Press Jog/Purge
button to clear error.
ERR MOTR
The motor error indicates 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. Press Jog/Purge button to clear error.
ERR WFS
The wire feed speed error indicates actual
wire feed speed does not match wire feed
speed command. Press Jog/Purge button
to clear error.
ERR STRT
The start error occurs if the user has the
trigger held for more than 3 seconds without
striking an arc, or if a valid arc voltage and
current is not detected. The 3 second arc
start error time can be changed using an op-
tional PDA with File Management software.

temperature error.
ERR STOP
The stop error occurs as result of
obstructions in the wire feed system or a
faulty wire drive system. Check wire feed
and wire drive systems. Press Jog/Purge
button to clear error.

reestablishing gas flow to the gun, and then
pressing the Jog/Purge button.
ERR COOL
The cool error indicates no coolant flow in
water flow switch option. The error may be
reset by reestablishing coolant flow to the
gun, and then pressing the Jog/Purge
button.
ERR GND
The ground current error occurs if weld
current is detected in the earth ground
connection. May be caused by a conductor
making contact with unit chassis. Check
and repair feeder weld connections. Press
Jog/Purge button to clear error.
ERR
STOP
Indicates an arc
stop error.
ERR
LINE
Indicates a line
error.
ERR STUK
The stuck error occurs if the welding wire
sticks to the workpiece at the end of a weld.
May be caused by poor weld conditions.
The error may be cleared by cutting wire
from workpiece, and pressing the Jog/
Purge button.

ERR LINE
The line error indicates input power is
outside of unit operating range. Check and
correct input power. Press Jog/Purge
button to clear error.
ERR ARC
The arc error indicates an arc outage
occurred possibly from a wire feeder error
or power source error. Check wire feeder
and power source. Press Jog/Purge button
to clear error.
