Voltage regulation wrt resistive and inductive loads...

In a portable generator. Does one type of load vs the other make it more difficult for a typical portable generator to maintain constant voltage? Yes, of course. The arc-generation of a welder (and its internal control switches) is a very difficult load, even for a full electric power grid let alone a small generator. This is because the so-called 'power factor' is indeterminate. Computer power supplies are also somewhat troublesome (but for a different reason: they respond to brown-out by increasing their current demands). The most reliable way to drive a welder from a generator, is to buy a welder that's gas-powered. |

Gunner The methodology of the left has always been: 1. Lie 2. Repeat the lie as many times as possible 3. Have as many people repeat the lie as often as possible 4. Eventually, the uninformed believe the lie 5. The lie will then be made into some form oflaw 6. Then everyone must conform to the lie |
