- 23 - Abstract of the Disclosure Title: WELDING TORCH WITH FUME-EXTRACTION HOOD The torch is of the kind which includes a hollow handle, attached to a goose-neck. Smoke etc is drawn through the hollow body of the torch, ie the goose-neck and handle, and into a vacuum hose attached to the handle. A fume extraction duct is attached to the body, and the duct is in several movable parts which can articulate. The combersome vacuum hose is attached not to the fume extraction duct, but to the body. O-rings are provided at the various joints and connections in the duct, to provide friction. The friction is such that the articulation movements are light enough that the welder can manipulate the duct with his hands, without tools, and without breaking the arc, and yet the duct is stiff enough to hold itself in the as-set position, after the welder releases the duct.
