MESSAGE EXPLANATION
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
operator 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
welding will stop the message from being displayed. Pressing any incre-
ment or decrement arrow keys or gun switch while welding will temporarily
stop the message from being displayed (approximately 1.3 sec. ) allowing
the operator 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. Pressing any key or gun switch when the operator is not
welding will stop the message from being displayed. Pressing any incre-
ment or decrement arrow keys or gun switch while welding will temporarily
stop the message from being displayed (approximately 1.3 seconds) allow-
ing the operator to view the increase or decrease in that setting.
Only displayed at power-up. Displays the part number of the ROM
ASSEMBLY 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 connected and the Manual key must
be pressed to enter any Spool gun welding procedures.
Reminder that the Spool gun has been removed and the Process key must
be pressed to enter SP-250 weld settings. This message may also be dis-
played if there is an open lead in the spool gun 6-pin plug assembly.
