A torch for use in welding operations during which smoke and/or fumes are created has a nozzle and a handle connected to a conduit extending between the handle and the nozzle. A fume extraction duct extends from the nozzle and through the handle. An annular member surrounds the axial end of the nozzle and has a plurality of openings oriented such that fumes and ambient air are extracted in a direction substantially parallel to the longitudinal axis of the nozzle. A switch is provided to control fume extraction between a full flow rate and a partial flow rate.

The invention claimed is: 1. A torch for use in welding operations during which smoke and/or fumes are created, said torch comprising: a nozzle having a longitudinal axis, an outer diameter portion and an axial end adjacent which welding occurs; said nozzle comprises a wire electrode, terminating in an arc tip; a handle connected to a conduit extending between said handle and said nozzle and through said handle; a fume extraction duct extending from said nozzle and through said handle; and an annular member having a portion with an outer diameter surrounding said axial end of said nozzle wherein said portion of said annular member is parallel to said outer diameter portion of said nozzle; said annular member comprising a flared wall portion extending radially outward from said axial end of said nozzle, said annular member flared wall portion having an outer diameter greater than said outer diameter of said annular member, said annular member comprising a plurality of openings formed on an outer surface of said flared wall portion outer diameter around a periphery of said annular member, said openings are oriented perpendicular to said longitudinal axis of said nozzle oriented such that fumes and ambient air are extracted directly into said annular member in a direction parallel to said longitudinal axis of said nozzle prior to entering said nozzle. 2. The torch of claim 1, further comprising a vacuum pump assembly connected via said conduit to said fume extracting duct and said nozzle. 3. The torch of claim 1, wherein said handle of said torch further comprises a switch for controlling operation of said torch. 4. The torch of claim 3, wherein said switch controls a fume extraction flow rate between full and partial flow. 5. The torch of claim 1, further comprising an outer wall surrounding said fume extraction duct and said conduit. 6. The torch of claim 5, further comprising a wire guide tube extending within said outer wall and through said nozzle. 7. The torch of claim 6, further comprising a manifold which comprises a plurality of gas passageways for directing shielding gas into the weld. 8. The torch of claim 7, further comprising a chamber formed at said axial end of said nozzle. 9. The torch of claim 1, further comprising a goose-neck shaped portion of said conduit formed between said handle and said nozzle. 10. The torch of claim 1, wherein said annular member forms a ring surrounding said axial end of said nozzle. 11. The torch of claim 1, wherein said openings are evenly spaced apart. 12. The torch of claim 1, wherein said openings are circular. 13. The torch of claim 1, wherein said nozzle comprises a second axial end, said second axial end comprises at least one tab formed on an inner diameter of said second axial end. 14. A torch for use in welding operations during which smoke and/or fumes are created, comprising: a nozzle having a longitudinal axis and an axial end adjacent which welding occurs; a duct found in said nozzle for extracting fumes from an associated work surface; a means for cooling said fumes, said means comprising an annular member having an outer diameter and a flared end wall having an outer diameter greater than said outer diameter of said annular member and a plurality of orifices oriented around said duct, and positioned on an outer surface of said flared end wall outer diameter perpendicular to said longitudinal axis of said nozzle; wherein said orifices extract fumes along with ambient air directly into said flared end wall, said orifices are oriented such that fumes and ambient air are extracted in a direction parallel to a longitudinal axis of said nozzle prior to entering said nozzle; and a vacuum pump which creates suction to extract said fumes and ambient air into said nozzle through said orifices. 15. A torch for use in welding operations during which smoke and/or fumes are created, said torch comprising: a nozzle having a longitudinal axis and an axial end adjacent which welding occurs; a fume extraction duct extending through said nozzle along said longitudinal axis; an annular ring comprising a body having an outer diameter and a flared end wall having an outer diameter which is greater than said outer diameter of said body and a plurality of orifices formed on an outer surface of said flared end wall outer diameter perpendicular to said nozzle longitudinal axis for extracting fumes and ambient air directly into said annular ring such that fumes and ambient air travel in a direction parallel to said longitudinal axis; a handle connected to said nozzle via a conduit; and, a switch mounted to said handle for controlling fume extraction flow rate between full and partial flow through said conduit. 16. The torch of claim 15, further comprising a valve connected to said switch, said valve having a first opening and a second opening spaced from said first opening, wherein said first opening is larger than said second opening. 17. The torch of claim 16, wherein said switch is in an off position, said valve first opening is aligned with said conduit extending from said handle and said nozzle, resulting in a full fume extraction flow rate. 18. The torch of claim 16, wherein when said switch is in an on position, said valve second opening is aligned with said conduit extending from said handle and said nozzle, resulting in a partial fume extraction flow rate. 19. The torch of claim 16, wherein said second opening has a first portion and a second portion having a diameter about half the diameter of said first portion. 20. The torch of claim 16, wherein said valve comprises a solenoid valve.
