A system, in one embodiment, may include a welding generator having a rotor and a stator, an engine coupled to the generator wherein the rotor comprises a mass configured to provide a substantial amount of inertia to smooth operation of the engine. A system, in another embodiment, may include an engine and an electromechanical device coupled to the engine, wherein the electromechanical device comprises a rotor having a mass effective to absorb energy from the engine during firing portions and return energy to the engine during non-firing portions of a cycle of the engine. A method is provided for removing a flywheel that substantially provides inertia to an engine of a welding system and providing inertia to smooth operation of the engine without or independent of the flywheel. Another method is provided that includes substantially providing inertia to an engine via a rotor of a generator.
