The suspended machine is designed for resistance spot welding of overlap joints of low-carbon and corrosion-resistant sheet steel, as well as cross-shaped joints of reinforcement bars of types BI, AI, AII, AIII.
Working fluid of the hydraulic drive — oil.
The machine is made with three types of controllers:
— РКСМ — produced in Ukraine
— SERRATRON 1А or SERRATRON 1В — produced in Spain.
The controller 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 of the welding current during welding.
The machine can be equipped as a pincer spot welder or a push welder with a manual compression drive.
The welding process control system allows setting individual welding modes for each weld gun.
