AIR FLOW METHODS AND SYSTEMS FOR A WELDER-GENERATOR
First Claim
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; and
an 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.

Abstract
Configurations of internal components of a welder-generator are provided to improve efficiency of the cooling of the internal components. The disclosed embodiments include configurations in which a single fan, such as an engine fan, drives a single airflow path through the welder-generator. Additionally, embodiments are provided with configurations 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. In disclosed embodiments, 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.
