Abstract:
An example welding wire feeder includes: a push motor configured to feed welding wire from a wire source; a first sensor configured to provide push motor velocity feedback; and control circuitry configured to control the push motor and a pull motor of a welding torch coupled to the welding wire feeder by: controlling a push motor velocity of the push motor and a pull motor velocity of the pull motor based on a target wire feed speed; and compensating each of the push motor velocity of the push motor and the pull motor velocity of the pull motor based on the push motor velocity feedback and based on pull motor velocity feedback, wherein the push motor velocity and the pull motor velocity are based on a target wire tension.
