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

ERR UNKN
The unknown error indicates an error was

error condition is unknown. Make sure
welding power source is isolated from the
welding fixture. Press Jog/Purge button to

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.

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.
