ABSTRACT:
A moveable welding station. An exhaust hood mounted atop a pair of depending legs with a welding curtain extending downwardly from the hood and defining the work area. An exhaust fan mounted to the hood pulls air upwardly from the work station through a bottom slot and then radially into a plurality of cylindrical air filters. An air passage is provided from the hollow central portions of the cylinders upwardly through a pair of charcoal filters exiting into the ambient air surrounding the welding station. A second source of pressurized air is directed via air tubes into the hollow central portions of the cylindrical filters in a direction opposite of the normal air flow in sequential pulsed fashion dislodging foreign particulate matter from the cylindrical filters. A dust pan removably mounted to the hood receives the foreign particulate matter allowing for the automatic cleaning of the filter.
