We present a professional automatic line for the production of welded mesh for fencing panels or gabions. The device is based on 4 inverter 1000Hz transformers with 200kVA power at P-50% and 51 three-chamber welding cylinders with a pressure of 330 kg at 10 bar each. The device is designed for welding mesh with a maximum dimension of 2500mm x 2500mm from rods of diameters 4-6 mm. All rods are automatically fed through 3 trays: transverse, elongate and lateral to feed an additional transverse bar. At the end of the receiving table there is an automatic pickup and palletizing station.
