Abstract: Methods and apparatus to communicate via a weld cable are disclosed. An example weld circuit communications device includes a receiver circuit, a processor, and a local communications adapter. The receiver circuit to receive a communication via a weld circuit while current is flowing through the weld circuit or after the current has stopped flowing through the weld circuit, the communication including weld voltage feedback information measured at a device remote from a power supply and remote from the weld circuit communications device while the current is flowing through the weld circuit. The processor generates power supply control information based on the weld voltage feedback information. The local communications adapter transmits the power supply control information to control welding-type power output by a power converter to regulate a weld voltage to a weld voltage setpoint.

Abstract: A welding method includes feeding a welding electrode axially from a welding torch, moving the welding electrode radially in a desired pattern with respect to a central axis of the welding torch by a motion control assembly within the welding torch, transmitting from control circuitry a signal corresponding to a position of the welding electrode relative to a weld joint or weld pool, advancing the welding torch or a workpiece to establish a weld, and transferring material from the welding electrode to a first location in an area of the weld pool. The welding electrode moves radially while feeding the welding electrode from the welding torch, the material from the welding electrode is transferred to the first location during a first cycle of the desired pattern, and the first location is controlled based at least in part on the signal.

Abstract: A contact tip assembly with a preheating tip comprises a welding power source configured to provide welding current to a welding circuit, the welding circuit comprising a welding electrode and a first contact tip of a welding torch. The assembly also includes an electrode preheating circuit configured to provide preheating current through a portion of the welding electrode via a second contact tip of the welding torch, and a voltage sense circuit to monitor a voltage drop across the two contact tips, and the electrode preheating circuit adjusts at least one of the first current or the preheating current based on the voltage drop.

Abstract: Systems and methods are disclosed that provides a helical wire for use in welding applications. A torch can be adapted to form the helical wire from a straight wire and to provide the helical wire as a consumable electrode in a welding or cladding application. The helical wire can be, for example, solid, tubular, or seamless tubular. The torch concurrently forms the helical wire and provides welding current for the welding or cladding application.

Abstract: Apparatuses, systems, and/or methods relate to a welding system that provides a field former for use in welding applications. The welding system includes a welding torch that includes one or more coil windings through which flows current that forms a magnetic field. The magnetic field is concentric to the tool center point. An arc is formed between the electrode and a workpiece. The magnetic field forces the arc in a center of the welding torch or the one or more coiled windings.
