TROUBLESHOOTING & REPAIR
An attempt was made to recall a setup from memory that has improper set-
tings due to excessive electrical interference. The SP-250 will recall the
setup and reset the improper data to within machine limits. However, all
settings should be checked, properly set if needed, and then resaved to that
memory. This message alternates with the second message until the
Process key is pressed.
Unit shut down even though trigger was closed. There is an excessive cur-
rent draw on the motor. Check for proper size tip, liner and drive rolls, for
any obstructions or bends in the gun cable, and any other factors that would
impede the wire feeding. To resume welding, simply pull the trigger.
Indicates that an error has occurred due to excessive electrical interference.
All of these error types turn off the arc voltage, wire feed speed, and sole-
noid. Press the Process key, per second message, and check all settings
before continuing to weld.

DATA
Reminds the operator that the gun switch is being used to toggle between
memory 4 and memory 5 and, therefore, is not able to control IPM or arc
VOLTS.
Reminds the operator to change the electrode polarity to negative when
Innershield wire type is selected.
Indicates to operator that the input line voltage is too low to obtain the out-
put set on the machine. 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 less than 75% of nominal line or if the voltage level set on the
machine is not obtainable at that line voltage and load current. The opera-
tor should check if the reconnect panel is wired properly. Lowering the set
VOLTS and/or IPM can eliminate the message. 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.) allowing the operator to view the increase or
decrease in that setting.
