Abstract
The present invention is directed to an apparatus and method for controlling a wire feeder. The wire feeder includes a wire feeder motor configured to drive delivery of a welding wire at an actual wire feed speed (WFS) according to a welding-type process. The wire feeder also includes a processor configured to adjust motor calibration parameters such that actual WFS matches a desired WFS.
Claims20
A wire feeder comprising:
- a wire feeder motor configured to drive delivery of a welding wire at an actual wire feed speed (WFS) according to a welding-type process;
- and
- a processor configured to adjust motor calibration parameters such that actual WFS matches a desired WFS.
A method of calibrating a wire feeder comprising the steps of:
- entering a calibration mode for a wire feeder motor;
- setting a desired WFS;
- measuring an actual WFS;
- comparing the actual WFS to the desired WFS;
- if the actual WFS varies from the desired WFS, modifying a calibration profile until the actual WFS is within a desirable tolerance of the desired WFS;
- and
- storing a modified calibration profile.
4 more elements
A wire feeder calibration system having a processor configured to operate according to:
- a control mode to control a wire feeder motor during startup;
- a feedback mode to determine an accuracy of wire feeder control after startup;
- and
- a calibration mode to adjust a motor control profile to increase control accuracy when in the control mode.
1 more element
A wire feeder comprising:
- means for receiving a desired operational speed;
- means for controlling a wire feeder motor based on a calibration profile of the wire feeder motor;
- means for determining an actual operational speed of the wire feeder motor;
- means for comparing the actual operational speed to the desired operational speed;
- and
- means for adjusting the calibration profile of the wire feeder motor if the actual operational speed substantially deviates from the desired operational speed to calibrate the means for controlling the wire feeder motor.
3 more elements
A wire feeder comprising:
- a wire feeder motor configured to drive delivery of a welding wire at an actual WFS according to a welding-type process;
- and
- a processor configured to monitor wire feeder motor operations during a first welding-type process and adjust a motor calibration profile during the first welding-type process such that wire feeder motor operations in a subsequent welding-type process matches a desired wire feeder motor operation profile.
