I have a maxstar 350. The post flow is set to auto. How does it determine how long to kee the gas flowing before it turns it off?

Post flow set to Auto
POST FLOW [POST] - If the TIG process is active (see Section 5-7), use control to set length of time gas flows after welding stops.
AUTO POST FLOW - Creates a post flow time scaled at 1 second per 10 amps of the peak weld amperage for a given weld cycle. Auto post flow is limited to a 8 second minimum, or to the maximum preset post flow time.
Application:
Postflow is required to cool tungsten and weld, and to prevent contamination of tungsten and weld. Increase postflow time if tungsten or weld are dark in ap- pearance.
