Direct (Rectified) Current Seam Welding Machines MSHV-4801, MSHV-4802, MSHV-4802.1, MSHV-4803
These machines are intended for use in melting facilities and are designed for rectified current seam welding with edge squeezing of steel strips made of low-carbon and low-alloyed steels with up to 0.35% carbon content, and electrical-sheet (dynamo) steels with up to 1.8% silicon content, as well as plated steels (MSHV-4802.1). The machine can weld transitional seams using strips of twice as different thickness.Technical description:
