An integrated welder, generator and compressor unit that includes a housing that
at least partially contains components of a welder, generator and an electric compressor.
An engine, an electric current generator, and an electric air compressor are at
least partially mounted in the housing. The electric current generator is at least
partially connected to the engine to be at least partially driven thereby. The
electric air compressor can be at least partially powered by the electric current
generator during the operation of the engine. Alternatively, the air compressor
can be powered by an external source of power without the use of the engine/generator.
