Claims

[Claims for Utility Model Registration] (1) The flange of the object to be welded is held between a pair of electrode rollers, and the entire object is moved along the flange by holding the handle while applying a voltage between the electrode rollers. Accordingly, in the manual seam welding machine which sequentially welds the flanges while rotating both electrode rollers, the pair of electrode rollers are respectively attached to the tips of rotating bodies, and the pair of rotating bodies are respectively attached to these. The rotary body is pivotally supported by a cover body that covers the rotary body, a rotational drive source is connected to the other end of the pair of rotary bodies, and each of the pair of cover bodies forms a head case together with each cover body. An arm extending in a direction away from the electrode roller is integrally provided, and the pair of head cases are rotatable through a central axis at an intermediate portion of each head case so that the pair of electrode rollers can move toward and away from each other. An air cylinder having an end of a cylinder body attached to one arm and a piston rod connected to the other arm is interposed between the rear portions of the arms, which are connected to each other and are opposite to the electrode roller with respect to the central axis. 1. A manual seam welding machine, wherein the handle is provided on the head case. (2) The flange of the workpiece is held between a pair of electrode rollers mounted on a trolley, and a secondary voltage of a welding transformer mounted on the trolley is applied between the two electrode rollers, and a rotational drive source is activated. In a self-propelled seam welding machine that sequentially welds the flanges while moving the entire electrode roller along the flanges by rotating each of the electrode rollers, the pair of electrode rollers are each attached to a tip of a rotating body. each of the pair of rotating bodies is pivotally supported by a cover body covering each of the rotating bodies, a rotational drive source is connected to the other end of the pair of rotating bodies, and each of the pair of cover bodies is provided with: An arm extending in a direction away from the electrode roller, which forms a head case together with each cover body, is integrally provided, and the pair of head cases are arranged so that the pair of electrode rollers can come into contact with and separate from each other at an intermediate portion of each head case. The ends of the cylinder body are attached to one arm, and the end of the cylinder body is attached to the other arm, between the arms that are rotatably coupled to each other via a central axis, and which are on the opposite side of the electrode roller with respect to the central axis. A self-propelled seam welding machine, characterized in that an air cylinder connected to a piston rod is interposed, and the center shaft is connected to the truck.
