Seam welding machine by direct current ÌØÂ-48.01, ÌØÂ-48.02, ÌØÂ-48.03
Description
Machine is designed for resistance seam welding by direct current with crushing strip edges made from low carbon and low alloyed steels with carbon content up to 0.35% and electric (dynamo) steels with silicon content up to 1.8%, as well as steels with coating (ÌØÂ-48.02.1) as a part of metallurgical aggregates. It is acceptable to weld transition seams of strips which differ in thickness two times.
