Abstract

The present application relates to a submerged arc welding machine and a submerged arc welding method, the method including: preparing a plurality of tables (22a, 22b) in which two or three manipulation parameters and function values are associated with each other in order to associate a plurality of the manipulation parameters for manipulating an AC waveform of a current output from a welding power supply (1) and parameters for determining the AC waveform in combination with the plurality of manipulation parameters with matching between an effective value of the output current and a predetermined current set as a constraint condition; receiving the plurality of manipulation parameters; and calculating the parameters with reference to the plurality of tables (22a, 22b) by using the plurality of received manipulation parameters.
