Abstract: An arc welder designed to receive its principal source of power from a vehicle's alternator which is controlled by a special controlled battery charger. This welder has a 36 volt battery system that is used as a supplement power supply. The principal power source only can be used in welding or the supplement power supply can be used in welding or both principal power source and the supplement power supply can be combined at the work load in welding, and during the time when the arc is not generated the battery system is being re-charged. Inductors and a switching system are used to control the current flow from the battery system to the work load in welding. Also, the battery system can be used direct for heavy duty cutting and/or for extra-heavy duty welding thus giving the operator an extremely wide range of current to fit his needs.

Abstract: An inductor generator for welding in which: a plurality of generator elements are combined and incorporated in a single generator and respectively provided with excitation windings to render the generator elements self excitable; a constant-current control circuit is inserted between each excitation winding and corresponding field winding in order to stabilize the field current which has been once set. The constant-current control circuits are so mutually connected that compensation operation is possible so that, when the field current of any of the generator elements is varied, fluctuations of the output values of the other generator elements are prevented, these fluctuations otherwise being due to various effects acting mutually between the generator elements, particularly magnetic effect, in spite of the fact that the field currents of the other generator elements are being maintained at their set values. As a result the above described problems of the prior art are overcome.
