ERR TACH

Tach error for Tach A 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.

Tach error for Tach B 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 erro r, when enabled, occurs if the
trigger is held longer than three seconds
without an arc start. The error may be
cleared by releasing the trigger, and
pressing the Jog/Purge button.
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.
ERR FLOW

The flow error indicates no gas flow to the
gun. The error may be reset by
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. Turn
power off and back on to clear 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 TEMP

The temperature error indicates welding
power source has overheated and
shutdown. The error may be cleared by
allowing unit to cool down, and pressing the
Jog/Purge button. If problem persists,
check fan motors and thermistors for proper
operation. If unit is not overheated, check in-
put line voltage. If input line voltage is okay,
contact nearest factory authorized Service
Agent.
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.
