CONTROLLED POWER SOURCE WITH APPARATUS AND METHOD INCLUDING INDICIA OF CONTROL MEANS ACTUATION AT OPERATIONAL LOCATIONS SELECTIVELY SPACED FROM SOURCE, AS FOR, BUT NOT LIMITED TO, WELDING OPERATIONS

摘要

There is disclosed an operative, manipulated at a production station, and a control housing easily and readily mechanically connected to a conventional regulatable source of power, as a welding machine. The control housing has incorporated therein an actuator including circuitry, as with a fractional horse power motor being connected through a transmission to drive the means that regulates the power delivered from the source. In one form of the invention the circuitry includes a single conductor, and in another form, not more than two conductors. With conductor wire connected switch operator manipulated at his work station, he sets in actuation change of power delivered to his station, with change achieved being indicated to him in one form visually by performance, in another form by count of length of switch closure, in another form by count of successive switch closures, and in still another form by count of audible clicks or "beeps" indicative of steps effected in power regulation at source.
