7-2. Diagnostics
The following error messages are shown on the upper and lower displays to indicate specific errors. Explanations are in the text below:
ERR
TACH
Indicates a tachometer error.
ERR
MOTR
Indicates a motor error.
ERR
WFS
Indicates a wire feed speed error.
ERR
STRT
Indicates an arc start error.
ERR
STOP
Indicates an arc stop error.
ERR
FLOW
Indicates a gas flow error.
ERR
COOL
Indicates a coolant flow error.
ERR
GND
Indicates a ground current error.
ERR
STUK
Indicates a wire stuck error.
ERR
TEMP
Indicates a temperature error.
ERR
LINE
Indicates a line error.
ERR
ARC
Indicates an arc error.
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 error, 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.
