Gas Purge
After changing gas types, the gas lines must be purged in order to ensure that a dangerous
gas mixture does not exist. The gas console can be manually purged by setting the Gas
Test/Run switch to the three test modes for a minimum of 10 seconds each. NOTE: If
the Gas Test/Run switch is not set to test mode after power is restored to the system, the
gas console will perform an automatic purge prior to initiating a cut.
