Patent number: 10702942Abstract: An arc welder produces a weave pattern between workpieces. Each weld run comprises a center portion including a joining region between the workpieces and edge regions spaced apart from the joining region. The welder includes a power source that provides a welding waveform to a welding electrode to generate an arc to achieve a desired heat for welding, a welding torch, and an oscillator for oscillating the torch between the welding edge regions. A controller causes the power source to operate in a first mode utilizing a first waveform during welding within the joining region, and in a second mode using a second waveform, having a greater positive component than the first waveform, during welding within the edge regions. The controller determines a stickout value based on the first waveform but not the second waveform, and performs seam tracking based the second waveform but not the first waveform.Type: GrantFiled: March 30, 2017Date of Patent: July 7, 2020Assignee: LINCOLN GLOBAL, INC.Inventors: Steven R. Peters, John Benjamin Schaeffer, David A. Fink

Patent number: 10198591Abstract: Devices, systems, and methods for performing particularized encryption of confidential information within real-world data files that are subsequently stored within a cloud environment are described. Specific rules/logic are executed in a local computing environment to identify the type(s) and/or magnitude(s) of confidential information contained within each real-world data file. The identified type(s) and/or magnitude(s) of confidential information is thereafter specifically encrypted using various encryption processes. Once encrypted, the data is packaged and stored within a cloud environment without the need for further encryption at either the local computing or cloud environments.Type: GrantFiled: February 20, 2018Date of Patent: February 5, 2019Assignee: MASTERCARD INTERNATIONAL INCORPORATEDInventors: David A. Fink, Gang David Sun, Moira McCauley, Lisa Paulette Navarrette

Patent number: 5225661Abstract: A consumable welding element for arc welding comprising a steel sheath surrounding a compacted core containing metal alloying powders and an essentially 100% basic compound in an amount less than about 1.60% of the total weight of said element. The basic compound is calcium fluoride powder which is preferably in the range of about 0.1% to about 0.9% calcium fluoride powder by total weight of the element. As another feature the core of the element contains a specific agent for decreasing the amount of diffusible hydrogen in the weld metal. This new element may be a filler metal for TIG welding; however, it is preferably a consumable electrode for MIG welding.Type: GrantFiled: December 12, 1991Date of Patent: July 6, 1993Assignee: The Lincoln Electric CompanyInventors: Chang-Shung Chai, David A. Fink, John Gonzalez
