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 obstructions in the wire feed system or a faulty wire drive system. Press Jog/Purge button to clear error.
