ALTERNATIVE POWER FOR ENGINE DRIVEN WELDER
First Claim
1. A welding device, comprising:
- an engine-driven generator having a stator and a rotor coupled to a shaft rotatable through operation of an engine to generate a first electric current;
an energy storage device configured to store electrical energy and output a second electric current;
a renewable energy device that generates a third electric current based on a renewable energy source; and
a controller configured to;
select at least one of the engine-driven generator, the energy storage device, or the renewable energy device as a power source for a welding operation; and
select at least one of the engine-driven generator or the renewable energy device as a source to charge the energy storage device.

Abstract
The invention described herein generally pertains to a system and method for a welding device and, in particular, a hybrid welding device, that leverages a renewable energy source for a source of electrical current. The welding device can include one or more renewable energy kits that harvest renewable energy sources for performing a welding operation or a powering at least one of a device or component external to the welding device. The welding device includes renewable energy component that collects an input to convert to an electrical current that can be used as a replacement current, a supplemental current, or a complimentary current.
