TROUBLESHOOTING & REPAIR
Indicates to operator that the line voltage is too high, and the output voltage
has been reduced to protect the capacitor bank voltage rating limits. The op-
erator can continue to weld, but the voltage will be less than what is set on
the machine. This message occurs when the line voltage is greater than
121% of nominal line. The operator should check if the reconnect panel is
wired properly. Pressing any key or gun switch when the operator is not weld-
ing will stop the message from being displayed. Pressing any increment or
decrement arrow keys or gun switch while welding will temporarily stop the
message from being displayed (approximately 1.3 sec. ) allowing the oper-
ator to view the increase or decrease in that setting.
Indicates to operator that too much current is being drawn from the machine,
and the output has been reduced to prevent the current from exceeding safe
levels. This will typically occur in Manual mode using .045" (1.2mm) wire
and WFS greater than 275 IPM (0.7m/min.). Lowering the WFS will reduce
the output requirement and allow operation within the machine rating. Press-
ing any key or gun switch when the operator is not welding will stop the mes-
sage from being displayed. Pressing any increment or decrement arrow keys
or gun switch while welding will temporarily stop the message from being
displayed (approximately 1.3 seconds) allowing the operator to view the in-
crease or decrease in that setting.
Only displayed at power-up. Displays the part number of the ROM ASSEM-
BLY currently on the PC board.
Indicates a checksum error in the software. Turn power off and back on
again. If this message persists, then replace the ROM assembly on the PC
board. Earlier units did not display the SXXXXX-X ROM ASSEMBLY num-
ber.
Indicates a fault in system RAM. Turn power off and back on again. If this
message persists, then replace the control PC board assembly.
Reminder that the Spool gun has been switched in and connected and the
Manual key must be pressed to enter any Spool gun welding procedures.
Reminder that the Spool gun has been switched out or removed and the
Process key must be pressed to enter SP-255 weld settings. This message
may also be displayed if there is an open lead in the spool gun 6-pin plug
assembly.
