OPERATION
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 dis-
played. Pressing any increment or decrement arrow keys or gun switch while weld-
ing 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 (7.0m/min.). Lowering the WFS will reduce the output requirement
and allow operation within the machine ratings. Pressing any key or gun switch
when the operator is not welding 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.) 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.
Indicates a fault in system RAM. Turn power off and back on again. If this mes-
sage 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-255 weld settings. This message may also be displayed if
there is an open lead in the spool gun 6 pin plug assembly.
