ABSTRACT:
A method and apparatus for wire feeding in an arc welding system includes a wire feed motor and a controller. The controller has an input circuit and an intermediate control signal. The input circuit includes a user selectable wire feed speed input, and the intermediate control signal is responsive to the user selectable wire feed speed input. The user selectable wire feed speed input includes a nonlinear potentiometer, that may be an arcuate, trimmed, potentiometer and provides either step or varying changes in the nonlinear first response, to produce at least two slopes or a varying slope. The intermediate control signal has a first response relative to the user selectable wire feed speed input. The wire feed speed has a second response relative to the intermediate control signal that is undesiredly nonlinear over a range. The wire feed speed has an overall response relative to the user selectable wire feed speed input. The input circuit includes a nonlinear stage resulting in the first response being nonlinear over the range that corrects the undesired nonlinear second response over the range, to produce a desired overall response over the range that is, preferably, more linear than the first and/or second response, or is substantially linear.
