Abstract

PURPOSE:To provide a measuring method of the discriminating resistance of an electrical fusion welding coupling, by which the discriminating resistance is surely measured and consequently fusion welding condition can not be erroneously judged. CONSTITUTION:The method concerned is for judging fusion welding conditions on the basis of the value of the resistance, which is measured with a controller 2, of a discriminating resistance 11 provided in an electrical fusion welding coupling 1 by connecting the terminals 10 of the electrical fusion welding coupling 1 with the terminals 10 of the controller 2 at fusion welding operation. Concretely, the value of the resistance 13 of a coupling main body 12 is measured. After the resultant value is confirmed to be below the setpoint, the value of the resistance of the discriminating resistance 11 is measured.
