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.
