Abstract
An integrated welder and air compressor combination includes a housing having an engine, weld current generator, and a belt-driven air compressor. A pulley arrangement is coupled to the engine, with the centers of the pulleys in a co-planar arrangement to enable driving the air compressor and engine accessory pulleys with a single belt. The engine accessory pulleys can drive, for example, one or more of an alternator, fan, or pump.
Claims19
An engine driven welder combination comprising:
- a welder housing;
- an engine mounted within the welder housing, the engine coupled to drive a crankshaft pulley and to an electrical generator to generate an arc welding current;
- an air compressor coupled to an air compressor drive pulley rotated by the engine;
- an engine accessory coupled to an engine accessory drive pulley;
- and
- a belt in driving engagement with the air compressor pulley and the engine accessory pulley, wherein when the engine rotates the crankshaft pulley, the belt drives the air compressor to produce compressed air and the engine accessory.

An engine driven welder combination comprising:
- an engine coupled to a crankshaft pulley;
- an alternator drive pulley coupled to the engine and to an electrical generator configured to generate an electrical current when the alternator pulley is rotated;
- an air compressor drive pulley rotatably coupled to the engine and coupled to an air compressor,
- wherein the crankshaft pulley, the alternator drive pulley, and the air compressor drive pulley are mounted to the engine such that the center of each of the pulleys that is configured to receive a belt is co-planar with the centers of the other pulleys that are configured to receive a belt.
