The stationary machine is designed for seam resistance welding with cross joint of the products of low-carbon steel with galvanic coating and without coating, and alloy steel, as well as for welding on of the heads and shells of coated steel.
The machine is made with a roller drive and inclined at an angle of 6 ° to each other using electrodes to weld on the heads and shells of sheet steel, both with galvanic coating and without coating.
The machine is equipped with a welding process control system built on a programmable controller, which provides automatic stabilization of the set parameters with indication of the actual values.
Controller type SERRATRON 1А or SERRATRON 1В (Spain).
