7-2. Diagnostics (Continued)
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.
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.
ERR POL
• The polarity error indicates the polarity is
different than the selected polarity. Check
and correct weld cable connections. Press
Jog/Purge button to clear error.
UNIT MEM
• The unit memory error indicates the PCM
board lost memory data. Press Jog/Purge
button to clear error.
UIM MEM
• The uim memory error indicates user
interface board lost memory data. Press
Jog/Purge button to clear error.
MOTR MEM
• The motor memory error indicates motor
board lost memory data. Press Jog/Purge
button to clear error.
WELD WAIT
• The weld wait error indicates unit was not
ready for a weld sequence. Press Jog/
Purge button to clear error.
MOTR COM
• The motor communication error indi-
cates motor board lost data communica-
tions. Press Jog/Purge button to clear error.
PLS WAIT
• The uim communication error indicates
user interface board lost data
communications. Press Jog/Purge button
to clear error.
OVER CRNT
• The over current error indicates welding
power source primary current is too high.
Check and correct input power. Press Jog/
Purge button to clear error.
LOW WFS
• The low wire feed speed error indicates
actual wire feed speed is lower than wire
feed speed command. Check for
