Abstract
PURPOSE: About equally spaced negative terminals surround a welding portion which is made the center positive terminal. So arranged electric circuit causes no stary current.
CONSTITUTION: A welding portion of material to be welded is made a positive terminal. Two or more of negative terminals are installed at about equal space around the positive terminal as the center. This forms an elctric circuit for the material to be welded, circulating between the positive and negative terminals. When a small diameter pipe is welded, it is preferred that about equally spaced bands are used as negative terminals to be placed at two locations around the pipe as the center. When a curved or flat portion of plate material is to be welded, about equally spaced plural negative terminals are preferably installed on the curved or flat surface with the welding portion as the center. In some case, magnetic material can be advantageously used as the negative terminal to be attached to the welding material. Preferably, electric welder grounding should be disconnected when welding.
