Engine Driven Welders incorporate a gasoline, diesel, or propane fueled engine coupled to an electrical generator to produce power for Stick, TIG, MIG and Flux-Cored welding. Engine driven welders are typically transported on a truck or trailer and are primarily used outdoors. The electricity generated by an engine driven welder powers fans, pumps, air compressors or other electrical tools commonly found on jobsites. During power outages, an engine driven welder can also be used as a backup generator.
