Sunstone’s Dual Pulse Capacitive Discharge Fine-Spot Resistance Welders provide the ideal resistance spot welding equipment. The 200, 400, and 600 watt second fine-spot resistance welders provide ample power for a large spectrum of applications, including battery pack manufacturing, at an affordable price. The welders’ dual pulse feature aids in the welding process. The first pulse heats the weld area to eliminate contaminants and then seats the weld electrodes. The second pulse is a higher energy weld that performs a clean, strong weld. Both pulses occur within milli-seconds.
