  • Patent number: 10537957
    Abstract: Systems and methods for wire feed speed control are disclosed. An example welding power supply includes a control panel comprising one or more input elements, and control circuitry. The control panel is configured to receive a first input relating to a material thickness and receive a second input to place the welding power supply in a first mode of operation, wherein the first input relates to a wire diameter. The control circuitry is configured to place the welding power supply in the first mode of operation when the first input is received from the one or more input elements; determine a coarse wire feed speed when the welding power supply is in the first mode of operation; receive a third input to fine tune the coarse wire feed speed; and fine tune the coarse wire feed speed based on the received third input.
    Type: Grant
