4.6 Weld Cycle State Displays and Alarms
When the welder is turned on, it performs a number of internal system
tests. If any errors are encountered, the welder will not enter the READY
state. If no errors are encountered, the welding parameters are set to those
stored. An error in reading the settings will cause cold start values to be
used.
Upon successful completion of the internal tests, the welder enters the
READY state and you will see READY displayed on the numeric display.
At this point you can set weld cycle parameters (as described in
Section 4.2 "Setting Weld Cycle Parameters"), or start a weld cycle.
If the welder does not successfully complete the internal tests and you
receive an error message, refer to 4.6.2 "Weld Cycle Alarms and Error
Messages" for a definition of the message.
4.6.1 Weld Cycle State Displays
During a normal weld cycle, the eight-digit NUMERIC DISPLAY shows the
current weld cycle state as indicated below.
