Spot welding machine by direct (rectified) current -80.02-1


Machine -80.02-1 is designed for spot welding by direct (rectified) current of various parts, including large ones, super duty products such as shell rings, trusses and other supporting structures. Maximum dimensions of welded parts are determined by electrodes stick-out, opening (span) of welding contour and upper electrode stroke.

Machine construction allows using it in all industrial spheres for aluminum and titan alloys welding, stainless, heat resistant and carbon steels, as well as some grades of brass and bronze.

The machine is equipped with programmable microprocessor control unit.
