ABSTRACT:
A system and method of controlling a wire feeder of a welding-type system is disclosed. A wire feeder including a controller capable of accepting a user input that includes desired mode, desired current output and desired voltage output. The controller then causes the welding-type system to operate according to the user input. The controller is also capable of acquiring output conditions of the welding-type system and determining a difference between the user input and the output conditions. The controller is further enabled to automatically adjust a speed of the wire feeder according to the user input mode and the desired current output or the desired voltage output.
