In this review, we dive deep into the technical specs of the Sequre SQ-SW3, a high-power capacitor energy storage spot welder designed for professional battery pack building. Unlike cheap battery-powered units, the SQ-SW3 uses two massive supercapacitors to deliver a peak output current of 2500A and 14kW of power, making it a serious alternative to the kWeld or expensive transformer-based welders.
