Apparatus and Method for Manual Metal Arc Welding

The present invention relates to a method and apparatus for providing additional shielding to a weld site when welding with a consumable self-shielding welding electrode. The method comprises the steps of producing a shroud gas curtain spaced radially outward from the electrode and substantially controlling the axial position of the shroud gas curtain relative to the distal end of the welding electrode during consumption of said electrode during use, wherein the shroud gas curtain comprises a radially outward component of velocity. The present invention also relates to a welding method and apparatus for providing fume extraction in a manual metal arc welding process.
