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.

An apparatus for winding coils onto a spherical body includes a frame, a feeder spool, a first hemispherical bobbin, a second hemispherical bobbin, a first spring-loaded pin, a second spring-loaded pin, and a motor arrangement. The feeder spool is rotationally mounted on the frame, has first and second wires wound thereon, and is configured to rotate about a first rotational axis. The first and second hemispherical bobbins are rotationally mounted on the frame and configured to rotate about a second rotational axis that is parallel to the first rotational axis. The bobbins are spaced apart from each other to define a wire-feeder gap through which the first and second wires may be fed. The motor arrangement is coupled to the first and second hemispherical bobbins and is configured to cause the first and second hemispherical bobbins to rotate in opposite directions about the second rotational axis.

Disclosed are systems and methods for feeding welding wire for welding-type applications. The wire-feeder system comprises a base platform, a spool hub, a drive roll assembly, and a wire guide assembly. The spool hub can be mounted to the base platform perpendicular to the base platform and configured to support a wire spool. The drive roll assembly can be mounted to the base platform, and having one or more sets of drive rollers configured to feed wire from the wire spool toward a welding torch. The wire guide assembly can be mounted to the base platform separately from both the wire spool and the drive roll assembly.

A rebar tying tool may include: a reel comprising a bobbin and a wire wound around the bobbin; a reel attaching part to which the reel is rotatably attached; a feeding unit configured to feed the wire from the bobbin around rebars; a twisting unit configured to twist the wire around the rebars; a type detector configured to detect a type of the reel; and a support supporting the reel attaching part, the feeding unit, the twisting unit, and the type detector. The type detector may include a movable member configured to move with respect to the support. The movable member may be at an initial position when the reel is not attached to the reel attaching part. The movable member may be at an attaching position according to the type of the reel when the reel is attached to the reel attaching part.

A wire processing system includes a tray having at least one tray surface configured to sequentially receive a first wire and a second wire from a wire feed system of a wire processing machine. The tray surface has a surface feature configured to provide a wire-to-surface coefficient of friction between the tray surface and the first wire higher than a wire-to-wire coefficient of friction between the first wire and the second wire laying on top of the first wire. The wire-to-surface coefficient of friction reduces movement of at least a portion of the first wire relative to the tray surface during movement of the second wire relative to the first wire.
