PURPOSE: To reduce a system size maximumly by rapidly connecting and disconnecting an electrically driven motor module having a rotation output shaft being a separate body to a welding head module via a driving module driving a rotor. CONSTITUTION: A first driving shaft is connected to a second driving shaft with a flexible driving shaft means, and a rotation driving power is guided from the first driving shaft to the second driving shaft while freely adjusting relative orientations of first and second housings. An electrically driven motor is supported with a separate and independent third housing, and a power driven motor module A having a rotation output shaft is formed by that. A freely releasable connecting means is arranged so as to connect and disconnect the rotation output shaft of the motor module to and from the second driving shaft by rapidly connecting the third housing to the second housing. Therefore, the welding head welding tubes having various sizes is rapidly switched in the same motor module or power unit. |
