The SARPO line has been conceived to insert a strip on each panel edge and to attach it to the panels through a spot welding system.
By means of spot welding, a reinforcement strip of the fin is inserted on the corrugated panel, just next to external base: these reinforcement strips permit a better welding of the components of the transformer tank.
The machine SARPO NT 1000 is equipped with 2 spot welding clamps and controlled from the central computer
The SARPO line permits to obtain each panel length with high precision and an easy welding on tanks frame.
