A baby cow is called a calf. Adult male cows are called bulls. Adult female cows are called heifers until they give birth; after they have given birth, they are called cows.
As long as there is a fuel supply of natural gas or propane, a well-maintained backup generator will keep running. If the Generac generator is running on propane, with a 500-gallon tank, it should run 24 hours a day for over a week. How loud are they? Generac generators are very quiet.

Assuming that I wouldn't need to run a welder at high amperage output for the light welding that I do around the house, I bought a Millermatic 211 welder that is rated at 20 amp input. The Generac generator has an electronic speed sensor and a circuit board that controls the throttle according to load.
