FUME MITIGATION SYSTEMS AND METHODS FOR ARC WELDING SYSTEMS

Abstract

A fume extraction system is designed for metalworking and other applications. The fume extraction system includes one or more motors and / or adjustment devices to control the fume extraction airflow. One or more sensors may monitor the welding torch to determine if a welding arc is present. The control circuitry is operable to receive signals from the sensor(s) and / or the power source to determine the presence of the welding arc. The control circuitry can then control the fume extraction system to adjust the extraction airflow based on the presence of the welding arc.
