Resistance Welding Gun with Motorized Arm Drive for Precise Electrode Positioning

Simple SummaryContent extracted from patent full text and abstract with AI.

The invention is a welding clamp (Schweißzange) specifically designed for resistance welding. It features two arms, each equipped with an electrode, where at least one arm is driven by a dedicated actuator. This actuator can move the arm from an open to a closed welding position using a linear force-controlled stroke.

Patent Abstract

The invention relates to a welding gun for resistance welding with two gun arms, wherein each gun arm has an electrode and with at least one welding electrode drive, wherein at least one of the two gun arms (2) is drivable with a welding electrode drive in the form of a second drive unit (3.1) and with this from a mutually spaced position of the gun arms (2) is movable with a translatory actuating movement in the form of a power stroke into the welding position.
