The Bernard Clean Air Fume Extraction Gun has been redesigned to be lighter and smaller than many standard fume extraction guns, providing welding operators with a more comfortable option for reducing weld fume and smoke, according to the company. To optimize weld fume capture, gas flow and weld access, the Clean Air Fume Extraction Gun offers an easy-to-slide nozzle shroud on the front of the gun that adjusts to one of four fixed positions. This gun has a crush- and snag-resistant vacuum hose that maximizes maneuverability and limits hang-ups on nearby equipment or fixtures. This gun is offered in 400-, 500- and 600-amp models with a 45- or 60-degree neck bend to maximize wire feeding.
