摘要： A method for controlling the speed of an engine driving a generator supplying electrical current to a load includes the steps of monitoring the current, increasing the speed when the current increases and decreasing the speed when the current decreases. The governor apparatus used to carry out the method includes a microcontroller having a current and frequency look-up table embedded in it. For some part of the monitoring step, the engine runs at a first speed, e.g., idle speed, or some moderate speed above idle speed. The increasing step includes detecting an increase in the current to a value, determining from the look-up table the frequency corresponding to the value and increasing the speed of the engine until the frequency of the current is the frequency corresponding to the value. To state it in other words, the new method and apparatus control the engine at a modest speed when the generator is unloaded or lightly loaded and increases engine speed and current frequency with increases in generator load.

摘要： A relay is provided for a transfer mechanism which transfers power between a utility source and a stand-by electrical generator. The relay incorporates contacts formed from two distinct materials. A backing portion of each contact is formed from copper and a contacting portion is deposited on the backing portion. The contacting portion is formed from tungsten. The arrangement of the contact minimizes the potential for failure of the transfer mechanism when the transfer mechanism is exposed to significant current and/or heating during operation thereof.

摘要： A "hot start" method for arc welding includes selecting a first weld current, setting a time interval, striking an arc, flowing a second, higher weld current through the welding rod and then, after a brief time interval, reducing the current through the rod to the value of the first weld current. Also disclosed is a new arc welder stator having two groups of slots around a core. The group of larger slots contains the weld current windings and slots in the group of smaller slots contain windings for timing, gate voltage, battery charging, auxiliary power and the like. A new cooling apparatus for an arc welder has an air duct and a "double-bladed" fan for flowing air along several paths and cooling both the welder control section and the generating section. A new method for electronically controlling engine speed in an engine-driven arc welder is also disclosed. Such method includes manipulating a current-selecting device, contacting a work piece with a welding rod, accelerating the engine to an elevated speed and then either maintaining such speed or reducing it, depending upon the value of weld current selected.

摘要： A transfer mechanism is provided for transferring the supply of power between a generator and utility source. The transfer mechanism includes a monitoring system for monitoring the power supplied by the utility source. The monitoring system starts the generator in response to a power outage from the utility source and stops the generator in response to the restoration of power from the utility source. A power relay has a utility input connectable to the utility source, a generator input connectable to the generator, an output connectable to a load, and a movable contact for selectively interconnecting one of the inputs to the output in response to the generation of power by the generator.

摘要： An air flow structure is provided for controlling the flow of air through an enclosure of a generator. The enclosure has first and second opposite ends and the generator includes an alternator and an engine driving the alternator. A first air flow generator draws ambient air into the chamber through the first end of the enclosure and directs the first portion of air in the chamber across the engine. A second air flow generator draws a second portion of the air over the alternator, and thereafter, combines the first portion of air directed over the engine and the second portion of air drawn over the alternator. The second air flow generator urges the combined air from the enclosure through the second end thereof.

摘要： A method is provided for exercising an engine-driven, electrical generator. The generator has a first operation mode wherein the generator generates a predetermined output voltage at a predetermined frequency with the engine running a predetermined operating speed and a second exercise mode. The method includes the step of running the engine at a predetermined exercise speed with the generator in the exercise mode. The predetermined exercise speed is in the range of 40% to 70% of the predetermined operating speed of the engine. In addition, in the exercise mode, the generator generates an exercise voltage that is less than the predetermined output voltage.
