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. If condition persists, contact nearest factory authorized service agent.
PLS WAIT
•The uim communication error indicates user interface board lost data communications. Press Jog/Purge button to clear error. If condition persists, contact nearest factory authorized service agent.
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.
ROBT MEM
•The robot memory error indicates robot lost memory data. Press Jog/Purge button to clear error.
E STOP
•The emergency stop error occurs if the user presses an emergency stop button. Reset the emergency stop button and press Jog/Purge button to clear error. Only applies to units equipped with E stop option.
RMD DONE
•The RMD done message indicates the RMD demo is completed. Pressing Jog/Purge button will change the screen to CYCL PWR on the display. Turn unit power off and back on again.
OVER AVG
•The over average error indicates that current is outside the average range for the set program parameters. Check and correct program parameters. Press Jog/Purge button to clear error.
UNIT COMM
•The unit communication error indicates the data bus on the PCM board is not functioning properly. Press Jog/Purge button to clear error.
OVER CRNT
•The over current error indicates welding power source primary current of the inverter is too high. Turn welding power source off and disconnect unit for servicing. Attempting to reset the display to continue welding may further damage internal components. A complete prepower check of the unit is needed including resistance measurements of R1 and R8 resistors on welding power source Interconnect board. Resistors should measure 30K ohms. Visually inspect electrolytic capacitors C1 and C2 for any possible damage. In the event of an over voltage condition, R1 and R8 could open potentially causing an imbalance in the power circuit. This condition would create excessive current in the inverter primary transformer and result in the OVER CRNT error.
