Attachment for the nozzle of an electric welding machine for welding with use of welding bar (3) under the supply of protected gas. The welder nozzle is designed with the end of a supply hose (2) for welding bar, protected gas, electric current and containing an outer casing (1) with a control pipe (7) set up for the wire bar to be fed out of, at which the outer casing connects a space (5) for the flow of protected gas. According to the invention, a cylindrical body (8) set up in the mouth of outer casing (1), in addition to which the body is equipped with a central hole (10) for the welding bar (3) and a number of canals or holes (13) for the discharge of gas from the inside of the outer casing to the welding site. The cylindrical body consists of an electrically insulated material that is also heavily resistant against the high temperatures which occur at the nozzle during such welding.<IMAGE> |
