Abstract:
A method of controlling a welding system includes controlling a weld current supplied to an electrode at a current ramp rate and determining an arc length based at least in part on the controlled weld current and a changing arc voltage. The arc length includes a distance between the electrode and a workpiece, and the arc voltage includes a voltage between the electrode and the workpiece.
