Database Export Screen

•

Export All

This option saves the current databases to
archive databases, backing up all system and
weld data. An

Export All

command should be

executed periodically as system settings are
changed and masters are developed. The
current and archive database file names are:
Current Database

Archive Database

Livco.mdb

Livcopy.mdb

Welddata.mdb

Weldcopy.mdb

WARNING

Welds cannot be monitored while

the Export All option is in use. Any remote
user interface windows must also be closed.

It may take more than ½ an hour to complete an

Export All

command. If the

Cancel

button is

used, the weld monitor must be shut down and
restarted. DO NOT shutdown the weld monitor
during this operation.

•

Export Masters

This option saves the current masters to an
archive database, backing up all current
masters. An

Export Masters

command should

be executed periodically as masters are
developed. The masters archive database file
name is

masters.mdb

. This command will

overwrite any masters written by a previous

Export Masters

command.

WARNING

Welds cannot be monitored while

the Export Masters option is in use. Any
remote user interface windows must also be
closed

. If the

Cancel

button is used, the weld

monitor software must be shut down and
restarted. DO NOT shutdown the weld monitor
during this operation.
