Abstract
An example fume extractor for a robotic welding torch includes: a neck clamp configured to attach to a neck of a robotic welding torch; an intermediate mount rigidly attached to the neck clamp; a fume duct coupled to the intermediate mount and extending over the neck of the robotic welding torch toward a nozzle of the robotic welding torch; and a fume manifold rotationally coupled to the intermediate mount and coupled to a fume hose, wherein the fume manifold, the intermediate mount, and the fume duct are configured to communicate a negative pressure from the fume hose to an end of the fume duct closest to the nozzle of the robotic welding torch.

A fume extractor for a robotic welding torch, the fume extractor comprising:
- a neck clamp configured to attach to a neck of a robotic welding torch;
- an intermediate mount rigidly attached to the neck clamp so that the neck clamp is positioned between the intermediate mount and the neck;
- a fume duct coupled to the intermediate mount and extending over the neck of the robotic welding torch toward a nozzle of the robotic welding torch;
- and
- a fume manifold rotationally coupled to the intermediate mount and coupled to a fume hose, wherein the fume manifold, the intermediate mount, and the fume duct are configured to communicate a negative pressure from the fume hose to an end of the fume duct closest to the nozzle of the robotic welding torch.
