Claims

[Scope of utility model registration request]

A movable block 5 is pivotally connected to a fixed block 3, which is biased toward the mesh pipe A by a pressure spring 2, with a shaft 4 disposed in a direction perpendicular to the mesh pipe A, and a contactor 3 is connected to the movable block via a shank 6. In the power supply device for the high frequency resistance welding method of the electric resistance welded mesh pipe, in which the welding current is supplied by press-contacting the contactor to the mesh pipe A, there is a wire parallel to the mesh pipe A between the movable block 5 and the shank 6. A power supply device for high-frequency resistance welding of electric resistance welded mesh pipes, characterized in that a shank 6 is pivotally connected to a movable block 5 with one shaft 8 interposed therebetween.
