Cooling for inverter-based engine-driven welding-type power supply

Abstract:

A welder-generator comprising an engine operatively coupled to a generator, weld circuitry, and a cooling system. The generator is configured to produce an electrical signal. The weld circuitry includes inverter circuitry configured to control characteristics of the electrical signal. A cooling system is configured to substantially block heat generated by operation of the engine from being transmitted to the weld circuitry.
