Abstract
Gun for cutting out sheet metal, of the type comprising an electrode (26) within a nozzle (19) with an outlet conduit (23) for a plasmagenic gas, mounted for free axial displacement relative to an electrode carrier (14), characterized by a drive shaft (7) for the rotation of the electrode carrier (14) and of the nozzle (19) about an external axial bearing pivot (22) of the nozzle and an outlet conduit (23) for plasmagenic gas which is eccentric relative to said axial pivot (22). This gun permits carrying out small cutouts of sheet metal by rotation of a plasma arc issuing from the conduit (25) rotating about the pivot (22). Application particularly to unbuttoning spot welded sheets.
