ASPA ZPm-80 spot welding machine

ASPA ZPm-80 spot welding machine manufactured in 2015 in Poland, is designed for resistance spot or projection welding of workpieces made of among others aluminium, stainless steel, brass and black steel. During the process, the machine heats two metal sheets of a maximum thickness of 6 mm until they reach a plastic state in order to join them into an inseparable whole after cooling. The joining of the workpieces is performed by electrodes through which pass a maximum current of 191 kVA for spot welding or 197 kVA for projection welding. The ZPM-80 spot and projection welding machine is equipped with an OMI CHW M21 chiller for electrode cooling, foot control and electrodes. The total weight of the machine is 690 kg.
