Systems and methods for automatically regulating the flow of fumes suctioned through a welding fume gun are provided. In certain embodiments, an automatic flow control assembly includes a vacuum system configured to suction a vacuum fume flow through an internal passage of a welding fume gun. The automatic flow control assembly also includes a sensor configured to measure a parameter related to the vacuum fume flow. The automatic flow control assembly further includes a flow regulation device configured to regulate an ambient air flow introduced into the vacuum fume flow. In addition, the automatic flow control assembly includes control circuitry configured to control the flow regulation device based at least in part on the measured parameter related to the vacuum fume flow.
