Title:
ENGINE DRIVEN ARC WELDING MACHINE
Document Type and Number:
Japanese Patent JP2763500
Kind Code:
B2
Abstract:
PURPOSE: To obtain two kinds of output with different voltages with the operation of a selection switch by connecting two sets of three-phase stator coil windings whose phases are mutually matched in a star and connecting the one-phase output terminal of the second stator coil winding to the neutral point of the first stator coil winding via the selection switch for making connection/ disconnection.
CONSTITUTION: A first stator coil winding 1 and a second stator coil winding 2 are subjected to three-phase star connection and U-phase output wire of the second stator coil winding 2 is connected to a neutral point 0 of the first stator coil winding 1 via a selection switch SW. Also, each phase output terminal of the first stator coil winding 1 is connected to input terminals (a), (b) and (c) of a first rectifier R1 and the phase output terminal of the second stator coil winding 2 is connected to input terminals a', b' and c' of a second rectifier R2, thus obtaining two types of high and low rectification output voltages by operating the selection switch SW and switching welding output to be low and high without using any complex switcher.
