Abstract
An arc welding system and method where burnback time (BBT) is correlated to wire feed speed (WFS). Means for feeding a wire electrode toward a workpiece and means for selecting a wire feed speed (WFS) are provided. Also, means for automatically adjusting a burnback time (BBT) of the wire electrode in response to the selected wire feed speed (WFS) is provided.
Claims20
A method to automatically adjust a burnback time in an arc welding system, said method comprising:
- selecting a first wire feed speed of a wire feeder of said arc welding system;
- and
- automatically adjusting an initial burnback time of said arc welding system to a first adjusted burnback time in response to said selected first wire feed speed.
An arc welding apparatus, said apparatus comprising:
- means for feeding a wire electrode toward a workpiece;
- means for selecting a wire feed speed of said means for feeding a wire electrode;
- and
- means for automatically adjusting a burnback time of said wire electrode in response to said selected wire feed speed.
1 more element
A method of establishing a burnback time in an arc welding system, said method comprising:
- correlating each of a plurality of burnback times to each of a plurality of wire feed speeds of said arc welding system;
- electronically storing said correlated burnback times and wire feed speeds within said arc welding system;
- and
- providing means for automatically adjusting a burnback time of said arc welding system to a correlated burnback time in response to a selected wire feed speed within said arc welding system based on said electronically stored and correlated burnback times and wire feed speeds.
