Patent number: 11931832Abstract: A welding system includes a power supply configured to generate a welding waveform. A wire feeder conducts the welding waveform to a wire electrode, and includes a drive motor that drives the wire electrode bidirectionally, a motor current sensor that senses a current level of the motor, and a controller that receives a current level signal from the motor current sensor and controls operations of the motor. A welding current sensor senses welding current level, and a welding voltage sensor senses welding voltage level, and the sensors are located with the power supply or the wire feeder. The controller is configured to determine a contact event between the wire electrode and a non-workpiece object based on the current level signal from the motor current sensor and one or both of the welding current level and the welding voltage level, and automatically retract the wire electrode upon determining the contact event.Type: GrantFiled: October 1, 2020Date of Patent: March 19, 2024Assignee: LINCOLN GLOBAL, INC.Inventors: Bruce J.

Patent number: 11504788Abstract: A welding or additive manufacturing system includes a power supply having a controller which controls operation of the power supply. The power supply provides a current waveform to a contact tip assembly having a first bore terminating at a first exit orifice and a second bore terminating at a second exit orifice. The first exit orifice is configured to deliver a first wire electrode and said second exit orifice is configured to deliver a second wire electrode. The exit orifices are separated from each other by a distance configured to facilitate formation of a bridge droplet between the wire electrodes while preventing solid portions of the first wire electrode delivered through the first bore from contacting solid portions of the second wire electrode delivered through the second bore, during a deposition operation in which the current waveform is conducted to both of the wire electrodes simultaneously through the contact tip assembly.Type: GrantFiled: January 27, 2020Date of Patent: November 22, 2022Assignee: Lincoln Global, Inc.Inventors: Matthew A. Albright, Matthew A. Weeks, Steven R. Peters, Andrew R. Peters, Bruce J. Chantry
