Air flow methods and systems for a welder-generator

摘要

Configurations of internal components of a welder-generator are provided to improve efficiency of the cooling of the internal components. configurations are provided in which a single fan, such as an engine fan, drives a single airflow path through the welder-generator. Configurations are provided in which a primary engine fan drives a first airflow path and a secondary generator fan drives a second airflow path through the welder-generator. Internal components are thermally aligned such that air circulates first through components with low critical operating temperatures and last through components with higher critical operating temperatures.

1. A welder-generator system comprising:
a welding device comprising:
an engine with a first side and a second side, wherein a fan is integral with the first side;a generator;a muffler;weld components; andan airflow path established through the welder-generator system such that when the fan generates airflow it flows from a front of the welding device to the weld components, to the generator, to the engine, to the muffler and out a back of the welding device in the recited order.
