Topic Productivity is raised, the narrow gap TIG welding equipment which can reduce production cost is offered.SolutionsIt turns among the narrow gaps in the narrow gap TIG welding equipment which does junction welding of the metal which has the narrow gap, and being the electrode melting the wire, without heating, it sends the wire where as for the electrode the wire which is sent from the front of the electrode of eccentricity form in thing, and two wires which possess two wires which are sent from the front and the rear of the electrode of eccentricity form in thing, and the narrow gap TIG welding equipment which are the electrode of the eccentricity form which grinds with angle of the 30 - the 45, welding traveling direction as standard, is heated, is sent from the rearThe both wire of the wire which is sent from the wire and the rear which are sent from the front of the electrode of eccentricity form being the wire which is done, furthermore, in two wires, heating, it is the wire which is sent.
