Patent number: 11618097Abstract: A resistance welder, which includes a clamp for supporting a detachable arm, the arm being constituted by a fixed part supporting a fixed electrode and a rotationally mobile part supporting a mobile electrode. The electrodes are intended to be crossed by an electrical current. The mobile arm of the clamp is pushed in its rotational motion by a thruster so that the extremities of the electrodes approach each other and grip the elements to be welded. The clamp further includes a shift measurement sensor, the value measured by this sensor being proportional to the distance between the extremities of the electrodes. It is thus easy to measure the distance between the electrodes and the measurement made on the piston can be used for other types of arms.Type: GrantFiled: July 21, 2020Date of Patent: April 4, 2023Assignee: GYSInventors: Bruno Bouygues, Mickaël Gabillard

Patent number: 11597027Abstract: Some examples of the present disclosure relate to welding torches having a thermal insulating plate (400). The thermal insulating plate is comprised of a thermally insulating material, and is positioned between a front housing (302) and a drive gearbox (324) of the welding torch. The front housing (302) is connected to a gooseneck that conducts electrical energy to a torch tip (i.e. front end) of the welding torch. The drive gearbox (324) includes a gear assembly configured to drive a drive roll that moves a wire electrode through the welding torch (e.g. toward the torch tip of the torch). The thermal insulating plate (400) acts as a heat dam to decrease and/or reduce thermal energy transfer from the torch tip of the welding torch (e.g. via the front housing) towards the rear of the welding torch (e.g. through the drive gearbox), where the thermal energy may heat the welding torch handle and/or damage some of the more expensive and/or sensitive components in the handle (e.g. a motor of the drive gearbox).Type: GrantFiled: February 27, 2018Date of Patent: March 7, 2023Assignee: ILLINOIS TOOL WORKS INC.Inventor: Craig Matthew Bondy
