Gas system purge cycle
When the system is turned on, or the operator changes from one process to another, the system automatically goes
through a purge process. The purge process has 2 stages; a preflow purge and a cutflow purge.
The preflow gas is turned on for 8 seconds with an auto gas console, or 12 seconds with a manual gas console.
The cutflow gas is turned on for 8 seconds with an auto gas console, or 12 seconds with a manual gas console.
There are 2 exceptions to the process described above.
Exception 1 – if the operator changes from a non-fuel gas process (O
2
/Air, Air/Air, or N
2
/Air) to a fuel fuel gas process
(H35/N
2
, or F5/N
2
) or the reverse, there will be 3 stages to the purge process. Nitrogen will purge the
gas system first, for 12 seconds. The preflow and cutflow purges will follow the nitrogen purge.
Note: error code 42 (low nitrogen gas pressure) will be displayed, if nitrogen is not connected to the gas system. If
error code 42 is not resolved in 3 minutes, it will be replaced by error code 139 (purge time-out error).
Exception 2 – no purge process will occur if the operator changes from any process to a nitrogen marking process.
