Abstract
A fume extraction system is designed for metal working and other applications. The fume extraction system includes one or more motors and/or adjustment devices to control fume suction airflow. One or more sensors may monitor a condition of the welding torch to determine if a welding arc is present. Control circuitry is operable to receive signals from the one or more sensors and/or power supply in order to determine the presence of the welding arc. The control circuitry can control the fume extraction system to adjust suction airflow based on the presence of the welding arc.
Claims18
A fume extraction system, comprising:
- one or more sensors configured to monitor one or more arc characteristics of an arc from an arc welding torch;
- a motor configured to generate airflow suction to extract air from a work space;
- and
- control circuitry configured to:
- receive information from the one or more sensors corresponding to the one or more arc characteristics;
- and
- activate the motor to generate the airflow suction based on the one or more arc characteristics.
A fume extraction system, comprising:
- one or more sensors configured to monitor one or more arc characteristics of an arc from an arc welding torch;
- one or more conduits arranged at a work space;
- one or more valves coupling the one or more conduits to a manifold of the fume extraction system;
- and
- control circuitry configured to:
- receive information from the one or more sensors corresponding to the one or more arc characteristics;
- and
- adjust a position of the one or more valves to connect the one or more conduits to the manifold based on the one or more arc characteristics.
