Apparatus and Method for Welding
The present invention relates to arc welding torch and a method of extracting fume gas from a welding site. The torch comprises a metal electrode and at least one shield gas port adapted to direct a shield gas curtain around the metal electrode and a welding site. At least one shroud gas port is spaced radially outward from the shield gas port and adapted to impart to an exiting shroud gas a radially outward component of velocity. Fume gas is preferably extracted from a position radially intermediate the shield gas curtain and the shroud gas curtain.
