An example fluid container fill indicator system generates an alert in response to a change in pressure at the exhaust conduit or the fluid container. In some example, the change in pressure causes a reed or whistle type device to generate an audible alert. In some examples, the alert is a mechanical and/or electronic signal based on a change in position or orientation of a valve in response to the change in pressure.

Methods and systems for fluid container volume indicator

Systems and methods for controlling an engine driven power system and/or a welding system from two or more control sources are disclosed. In some examples, multiple control devices or sources are in communication with a central control circuitry of the engine driven power system, and/or a welding system which is capable of managing commands from multiple control sources by prioritizing commands and/or limited the scope of control. In some examples, the central control circuitry controls the multiple control sources to update systems and displays to harmonize commands and/or data that originated at another source.

Systems and methods for remote control of a weld schedule of a welding power supply are disclosed. In some examples, a remote device is provided for monitoring or controlling the welding power supply, which controls and delivers power to one or more welding tools (e.g., a welding torch) and/or accessories (e.g., a wire feeder). The remote device includes a user interface to receive one or more inputs, which are provided to a control circuitry configured to transmit signals to or receive signals from the welding power supply via a remote transceiver. In some examples, the signals include data corresponding to one or more weld schedules.

Disclosed is an engine driven power supply that includes a housing having a first area that includes an engine and a second area that includes a temperature sensitive component. A fan is configured to force air in multiple directions through the housing. A temperature sensor to measure a temperature. And a controller controls the fan to force air in a first direction into the first area when the temperature exceeds a first threshold temperature value, and controls the fan to force air in a second direction into the second area when the temperature is below the first threshold temperature value.

Methods and apparatus for multi-directional fan

An example engine driven welder/generator system is disclosed that includes a turbo charged gasoline powered engine connected to an electric welder/generator. The welder/generator is configured to provide an output to an auxiliary welding system. The turbo charger system enhances operation of the gasoline engine by powering a turbine with engine exhaust to drive a compressor to increase intake of air, resulting in compressed air providing more powerful explosions in an engine combustion chamber once fuel is added and ignited. The resulting engine drives the welder/generator to provide a more consistent torque curve, while generating less noise per unit of power output in comparison to a diesel engine.
