Publication number: 20220032386Abstract: Systems and methods are disclosed for integrated compressed air cooling for welding systems. In particular, the disclosed systems and methods may employ compressed air to implement one or more welding processes (e.g., a gouging or cutting processes), with the compressed air being conveyed through such welding systems. In some examples, the compressed air is routed within the welding system to provide cooling for one or more components therein. For instance, components such as power conversion circuitry may heat up during the welding process. Routing compressed air to or near the components will introduce relatively cool air to the environment. As the passing compressed air heats in response to interaction with the heated components, heat is drawn from the components and/or the nearby environment.Type: ApplicationFiled: June 25, 2021Publication date: February 3, 2022Inventors: Adam E. Anders, Daniel J. Mortensen, Caleb M. Rosera

Publication number: 20220032389Abstract: Systems and methods are disclosed for automatically activating or deactivating a gouging torch. In particular, the disclosed systems and methods activate and/or deactivate a gouging torch based on a valve operation selection. For example, for welding power supplies and/or welding wire feeders configured to operate both wire welding processes as well as gouging, a valve can be integrated with a gouging torch, which can be adjusted to allow or arrest the flow of compressed air to the gouging torch. In response, the welding power source and/or welding wire feeder automatically changes one or more output characteristics, to switch between a wire welding process and a gouging process without requiring the operator to interact with either the welding power source or welding wire feeder.Type: ApplicationFiled: July 29, 2020Publication date: February 3, 2022Inventors: Adam E. Anders, Caleb M. Rosera
